a few pics of my project so far

Recommended Posts

I'm happy with how well the bits n bolts came up but a bit gutted I still haven't got the wishbones back yet and it's still in bits 😏

Unfortunately you can expect a few pipes under the bonnet to get brittle ,after 25 years of heat cycling,  I do have a few spare pipes from my oe v1 inlet kicking about but couldn't tell you which ones or what condition they're in . As they're all 26 years old too 😊

 

Might give my mate a nudge this evening,  see if he's pressed out those old bushes yet 🤞

Got the wishbones ,trailing arms and lateral links back with the bushes pressed out .  Brass wheel , wire wool and a coat of metal polish later ...

Looking much better , guess I'd better get the other one done   seal them up and get em fitted 😊

Although I couldn't hear any difference in noise from the crack in the headers , it's definitely been blowing bad and has cooked the paint on the underside of the cam cover 🙄

Ideally I'd like another decent set of headers but this years budget is fubared, due to the stroker build .   Haven't made the prettiest job of wrapping the oe ported headers but I did leave the oe crossover heat shield on and double up the wrap where the headers pass around the oil filter 😉

Headers and trick up pipe fitted .

Both wishbones sealed with dynax and fitted loosely,  as I need to refit the downpipe before fitting the H brace to the wishbone mounting bolts 😉

Screenshot_20200825-160843_Gallery.thumb.jpg.e452eec6ce7c8b92e5098c3a37bb1f55.jpg

Unfortunately the original o2 sensor on a v1 is pre up pipe (in the header collector) and I think the excessive heat in that area has cause it to weld itself into the old cracked headers. 

Completely ripped the o2 sensor bung outta the old headers trying to remove it , so I need to find a oe replacement 🙄

But shes about 3 hrs work from booking a geo now 😎

Cheers chap,  will admit the dynax has given them a more matt finish but tbh I'm hoping once it's back together....

I won't have the car up on axle stands for a while , so I won't see them very often 🤞

Its turning out to be a bit of a pita to source a genuine early o2 sensor and I've been quoted nearly £170 😏

Mind you the early o2 sensors don't tend to fail often , I'm fairly certain that the one that's stuck in the bung is the 26yr old original. 

So hopefully once I get a new one , i won't have to replace it anytime soon

I had to spend £150 for my version 3 o2 sensor being a WRX and not a turbo 2000 😬

Its only 2 years old however it’s helped it pass emissions both times. :biggrin:

My mapper tends to spend a lot of time mapping off boost and part throttle,  so my emissions have always been good . Even managed 310 miles from a tank , admittedly it was mainly motor way miles though  .

V1/V2 set up has the 02 sensor pre up pipe and they seem to never go wrong. Not sure if when they moved the o2 to the neck of the downpipe (v3 onwards) whether they changed the sensor type as well as position and loom plug .

Either way , it's made finding a new oe subaru o2 sensor for a v1/V2 quite difficult.  

Looks like Alyn as Asperformance has sourced one 😎 but it won't be here till next week, due to the bank holiday 😏

Mind you even once it's all back together and the o2 sensor fitted , I wont be driving anywhere until I get the 4 wheel alignment re done . As I don't want to scrub my front tyres to bits 😉

Had a call from Alyn at Asperformance yesterday afternoon , saying he'd sourced a new subaru early o2 sensor 😎

Screenshot_20200829-092059_Gallery.thumb.jpg.1a96db5e370d89a3c871cd58563fc1a5.jpg

And it landed on the door matt at 9am this morning 😊

So just need a break in the weather to get the old girl back together, then book in a geo for early next week 😎

Great result!

I’ve not tried Asperformance before.

Are you going for a fast road setup?

I spent some time scouring the threads for solving starting up issues. Great wealth of information that helped me to narrow down the issue to a faulty MAF connection.

His website was a bit "button moon" last time I looked but phone him and he'll take the time to discuss options that suit you best .Rather than just selling you anything and everything expensive 👍

Unfortunately I've lost my tried n tested fast road set up but think I've found one similar to try .

As for the scoob , it's back together at last 😎

Anti lift kit ,bushes ,wishbones (not tacky anymore ) headers , new o2 sensor , harvey trick up pipe and cusco H brace fitted .

Screenshot_20200830-124458_Gallery.thumb.jpg.b5f27b8e8d93e607d6e1198c561dc41a.jpg

Gotta find some new split pins for the bottom balljoint nuts , before dropping it on all fours but rest of the bay is back together too 😎

Screenshot_20200830-232922_Gallery.thumb.jpg.59962033f625c459f86daf02db5f5bd4.jpg

So hopefully I'll get booked in somewhere this week to get the alignment done

Missed that flat 4 roar but she's back on all fours , waxed and ready for the geometry set up tomorrow afternoon 😎Screenshot_20200901-175122_Gallery.thumb.jpg.c1f9bcee735e8a80fe18a25109785e0c.jpg

Fast road Geometry now done and happy to say that it's back to cornering like it is on rails  ,rather than driving like a crab lol .  There seems to be less nose lift under boost and nose dive under braking too 😎

20200903_161120.thumb.jpg.087cca5491f2e4cec2c0d72d1ed51af5.jpg

So it seems the anti lift kit ,bushes and H brace are doing their thing 😎

Trick up pipe seems to have made it spool slightly quicker , which is nice but probably means it will need a map tweek again 🙄

Or a full remap on a new link g4+ ecu 😉

Been enjoying the new geo , seems to work well 😊

Went to a local scooby scooby meet last sunday , sensibly socially distant with a nice selection of scoobies to walk round while chatting.  Only took a few pics and they don't do the cars justice tbh 1188967972_Screenshot_20200913-165314_SamsungInternet.thumb.jpg.f600d7db072c6d00e0fd42c14dbf9594.jpg1996889657_Screenshot_20200913-165231_SamsungInternet.thumb.jpg.79a2210aef2b7d131775d6e84d7c4191.jpg724201937_Screenshot_20200913-165411_SamsungInternet.thumb.jpg.7074fbe495524fe1e7378c1dbe2d4aca.jpg1601564971_Screenshot_20200913-165136_SamsungInternet.thumb.jpg.01af2bd49af7bf4297bbf873cf1334af.jpg

 

Even with the boost and duty targets backed off on the avcr , I'm still getting a bit of overboost 😏

I'd love to think that the trick up pipe and my self ported headers are out performing the old grouppe headers but it could well be that the ported headers haven't got a crack in them and are not leaking 🤔

Either way I either need to turn the boost duty down more or get the map tweeked again 😏

Then these popped up for sale ...

Screenshot_20200917-152508_Gallery.thumb.jpg.b522f3f0ad4fee8f8a0f106d03203660.jpg

Genuine 740cc nismos ,that should be good for 440hp ish 😊

I know the 20g won't make that sort of power and I've never got caught in numbers but it will hopefully allow it to just break the 400hp barrier 🤞 

Although the apexi f.c has done its job well for years 😎 I'll be ordering a link g4 plug in ECU tomorrow .😊

I had 3 parcels turn up today 😎

Linkg4x v1/V2 plug in ECU , link 3 bar map sensor,  ramair filter with spun trumpet and a air intake temperature sensor 😊

Screenshot_20200922-175127_Gallery.thumb.jpg.76c7d618483142f4b1b165cab0933d8a.jpg

So guess I'd better familiarize myself with the new link g4x software and swat up on how to wire in the a.i.t and my aem wideband to a link g4x 😉

Did think about fitting the 740cc's before I have everything for the install but , I don't want the scoob off the road for too long as I'm still enjoying driving it. 

After trawling the net and watching hpa /link tuning videos till my eyes hurt 🤓

   I finally think I know how to set the 740cc injector latency , wire in and calibrate the aem wideband , air sensor and link 3 bar map sensor 😎

I'm far from capable of mapping a ECU but the link g4x software seems quite user friendly . So hopefully once it's all wired in and calibrated , i should be able to tweek the base map enough to make it run well enough to drive the 60 miles to Attowes for him to map it 🤞

I bought the ECU from Martyn Jeffries at enginetuner,  as he spent loads of his time talking me through the link g4x set up . 

I now have a spare ECU case to fit the linkg4x plugin ECU into and I'm just waiting on some expansion board plugs, pins and wires to turn up .

So hopefully I can finally make a start on the installation at the weekend 😊

With everything now here , I was ready to get stuck in with the link g4x ECU install 😎

Screenshot_20201003-122757_Gallery.thumb.jpg.2a37aac524c7514217a47993b70fbe69.jpg

But its raining all this weekend and the mot is due at the end of the month . so I need to get the mot done before fitting the ECU and bigger injectors . As I doubt I'd get it all fitted and mapped to correct the afr for a emissions pass 😏

I still found something scooby to do in the dry ,thanks to Martyn at enginetuner sending me the canbus and expansion board header connections with pigtails

Screenshot_20201003-164021_Gallery.thumb.jpg.3542ddaf83d8c29cfbe76cb6e1714bae.jpg

Old stock ECU board removed and linkg4x fitted with pigtails plugged in .Screenshot_20201003-164110_Gallery.thumb.jpg.dc89c8205b9290d65d40597063bd6b7a.jpg

Although you can wire the wideband in via the expansion board ,Its recommended to use canbus . As it lessens ground loop , which can cause interference and slow or incorrect readings sent to the ECU.  This also frees up a input on the expansion board connection too ,which will be needed for ait sensor , map and anti lag switches 😉

Screenshot_20201003-164053_Gallery.thumb.jpg.c3bc698d05beddd774c78364c3c19472.jpg

Due to it fitting into a stock ECU case you need to cut a slot into the case to pass the canbus and expansion wires through ,along with the p.c link connector. 

Screenshot_20201003-164126_Gallery.thumb.jpg.57a4e12d95848790660f4def016fc1fe.jpg

I chose to notch a corner of the top case ,as it suits the natural bend of the pigtails. I'll be spending the rest of sunday afternoon sitting at the trusty kitchen table tagging wires and creating a pin list for wiring in the aem x wideband, ait sensor, link 3 bar map sensor and di switches .

Screenshot_20201004-123748_Gallery.thumb.jpg.dff52be4cb21bf16828e3e84d876b1a4.jpg

Although I'm gutted it's not fitted yet ,at least once I'm ready to fit it , it should make the installation easier having the prep work done beforehand.

Did a bit more prep by extending the air intake temp sensor wires , so they reach all the way to the ECU. 

Big thanks to @Jay762 for sending me some of these heat shrink wire joiners , never knew they existed 👍

Screenshot_20201010-173936_Gallery.thumb.jpg.741d1aebeb3b2353ced96f09ec87796b.jpg

So much eaiser just using my trusty zippo , rather than firing up the soldering iron 😎

Screenshot_20201010-173901_Gallery.thumb.jpg.3e2e506d135987938d0254969b168ed7.jpg

I'll slip heat shrink some bigger dia tubing over the join too before working out a route through the bay to the ECU. 

I'm currently running the apexi f.c map lead add on and 1.7 bar v3 onwards map sensor but the oe 1.2 bar map sensor is still plugged into the harness .

Seeing as the linkg4x will be running mafless and rely on the map sensor for fuelling calculations,  instead of a maf sensor.  I bought a brand new link 3 bar map sensor , then used the original v1/V2 map sensor plug and pigtail wires to connect it to the oe loom .

1.2 bar map sensor wires cut and new pins fitted .

Screenshot_20201010-173756_Gallery.thumb.jpg.5b7aab4566bf82448e7ef35cf7a21abb.jpg

It will now just plug n play into the oe loom 😎

Well hopefully 🤔 I'll just need to select the link 3 bar map sensor in the map sensor menus and check its calibrated with the linkg4x internal bap sensor 🤓

Mot booked in for Wednesday,  hope the forecast is good next weekend 🤞

Spent a bit of time trying to figure out the best position to fit the ait sensor 🤔

My Frankenstein inlet was originally from a early ra and has the 5th injector port blanked off but it's now not just after the throttle body .Due the the throttle body being on the reverse side of the inlet manifold 🙄

20201017_093933.thumb.jpg.5de1a070593742d672c49ef42d629b47.jpg

I also think that it would suffer from heatsoak and give false readings fitted directly into the ally inlet 😉

Just before the throttle body would be ideal but its directly above my "unguarded " auxiliary belt,  I've never had a auxiliary belt fail before but was worried if it did fail it would hit the ait sensor and "send it " into the inlet manifold. 

Screenshot_20201011-122931_Gallery.thumb.jpg.26271fabad2b017e292be610922f6393.jpg

Other option was above the dump valve but that's a bit too close to the rad and might suffer from heatsoak too 😏

20201011_143017.thumb.jpg.1bb4fd929512100fc8c4f4ac3823aaaf.jpg

Eventually I settled on notching the fmic to throttle body joiner , so I could fit the ait sensor close to the throttle body but it not being above the belt 😉

Screenshot_20201017-091808_Gallery.thumb.jpg.a34ee5bff37424ef336b5dfcabb5b548.jpg

After taking a list of pins and wire colours I sleeved the expansion board and canbus wires .Screenshot_20201017-091608_Gallery.thumb.jpg.b4df064685b9349cf1ca31582e0531d4.jpg

Unwired the hako interface (for connecting  to the apexi f.c) from the wideband and ecu .Screenshot_20201017-091640_Gallery.thumb.jpg.1dee0639544de48cb13f8d93667b18bd.jpg

As it's the first time I've fitted and set up a linkg4x ECU I didn't want to totally remove the apexi f.c yet , just in case I cant get it running well enough for the 60 mile trip to the mappers 🤞

So wideband canbus connected to the ECU canbus pigtail and ait sensor connected to ECU temp 3 /sensor ground pins on the expansion board 

Screenshot_20201017-091653_Gallery.thumb.jpg.a573fd50c3689754c12482df09624767.jpg

I don't want race car looking "missile" switches with red covers and would much prefer a more stealthy look . So I'm currently waiting for a couple of classic oe foglamp switches with plugs  to turn up . 

So I've run some wire from expansion loom digital input connections to the dash , ready n waiting for anti lag n launch 😊

Screenshot_20201017-091710_Gallery.thumb.jpg.2e9e01fdcdd5f994ef4a0fbda8b81616.jpg

So hopefully I'll plumb the link 3 bar map sensor in , plug the linkg4x in , set up map , ait and switches in the menus .

Then see how it starts and runs before fitting the bigger 740cc nismos,  as the original v1 sti map would only have 380cc injectors. 

If it runs ok 🤞🤞 then I'll fit the 740cc's enter the latency in the injector set up and try again

Linkg4x finally fitted 😎

Screenshot_20201018-131217_Gallery.thumb.jpg.4f087a9fa8977e8d9e684635c124ec4b.jpg

Ait sensor, link 3 bar map sensor ,tps and canbus connection for my aem x wideband all fitted , set up in the menus and calibrated.  Maf removed and ram air filter fitted ,along with oe 3 port boost solenoid reconnected. 

Screenshot_20201018-213438_Gallery.thumb.jpg.f4cd5118208ba46d78a68b2e87ee2d05.jpg

Still got to remove the avcr sensors and apexi map sensor but they're no longer connected .

Started off just starting it on the linkg4x base map , it ran with a low pig rich idle but revved cleanly to 3k .

Added the rough 555cc nismo dead times I found on the net ....

Screenshot_20201018-213528_Gallery.thumb.jpg.cad7085e86004d22875eeb157dbb34ec.jpg

Ran much closer to target afr's and still revs cleanly but does hunt a bit on idle . I've just added the bigger 740cc nismo dead times to the main fuel settings and will fit the bigger injectors before I start it up again 😉

 

@Falcongary Ive been reading up and watching a lot of vids for a few years , as I've always been interested in mapping . Tbh it's starting to sink in now I'm actually changing settings and seeing the difference it makes to afr and general running .

As for the apexi f.c , I offered it to you first fella and was intending on p.m'ing you now its removed .

Did you just want the apexi f.c , map lead add on lead , map sensor and hand controller?

Or the 555cc nismo injectors as well , to bring the current map on the apexi f.c in closer to your mods (save some mapping time) .

 

Either way most of its removed and I'm hoping the rest will be out tomorrow , if its dry 🤞
