a few pics of my project so far

Recommended Posts

Spent a bit of time cleaning off the old three bond liquid gasket from all the mating surfaces with a Stanley blade, as the engineers hot wash doesn't break it down .Then cleaned up the timing  belt belt tensioner bracket and p.s pump bracket .

When stripping the v4sti heads down one of the spring seats (washer that stops the spring wearing the ally head casings) was slightly damaged , so I've removed one from the v1sti heads to replace it with once I'm ready to fit the heads .

I've got loads to do but until the new pistons arrive pat wont start work , as they run 3 thou (3 thousand'th of a inch) clearance. subaru have different A and B sized pistons from the factory.  So even though the mahle 2186 stroker pistons are well made , he wants to measure each one and machine the bore to suit .

Hopefully by midweek the pistons, 2.5 nitrade crank ,king bearings ,bottom end gasket set ,oils ,filters and fluids should be here 🤞

Then I can drop the cdb ,pistons, crank and bearings off to pat and he can fit in the 93mm overbore, hone and thrust conversion. 

Arashi have updated me on the new ball bearing tdo5 20g billet and they're waiting on some bearing cases too assemble it 😏. So it's still not been posted yet but they'll send me the tracking info once it's on it's way 😊.

I'm looking forward to seeing how well a bb 20g on a 2.1 ltr as I was impressed with the journal core version.... well right up to the point it started blowing smoke everywhere 🤐

Once the blocks in Pat's shop , I can then concentrate on cleaning all the threebond and oil off the sump , clean and inspect the oil cooler and teardown check ,clean and reassemble the rcm oil pump . I just hope the engineer can find the time too squeeze me in , so I can make a start on the rebuild soon  😊

Did you go for the new coated King bearings?

Tbh I asked for acl but Alyn's delivery got returned back to the states before it arrived at his  , so he's waiting for his acl stock to come back again lol .

I have used king race bearings before, on the v7sti ej207 rebuild , they measured up and performed fine and I only chose acl as I've used them more often over the years .

Are you on about the high spec king bearings? (Possibly called "ultimate") 

 

As most race bearings are at least tri coated to protect and aid bedding in,  hence why not many engine builders do a long 1k + mile running in period anymore 😉

I rushed home hoping to find a big box of scooby stuff when I got home ,even though it's not due till Wednesday 🙄😏

Did get a email from arashi ,saying that my ball bearing 20g cartridge is in in transit though 😊

Yes the pMaxKote, was doing a comparison between the Mahle option and King, like the idea of the coating and the increased oil way.

looking forward to seeing how that new turbo performs

Think Alyn at Asperformance has a few options of bearings ACL , king ,mahle and even old skool  race clevite for big boy toys 😊 acl or king race bearings are fine for the 750hp rated rods in mine ,as I'll never want anywhere near that amount of power anyways 

As for the bb 20g cartridge I'm sure it will perform well and hopefully for longer too, lol .

I'd be happy with a responsive 380hp on the 2.1 stroker , although I doubt my 565cc nismos will allow it 🙄

Already got the stuff to fit the heads but I think this lot is the last of what I need. 🤔

so I'm gonna find the time to drop the pistons, block ,bearings and crank off to Pat segar tomorrow . Then hope he can fit me in soon 🤞

2x millers running in oil .

Premixed coolant 

Millers cfcs .

4 jdm black oil filters n sump washers. 

Mahle 2186 stroker pistons. 

2.5 sti end thrust crank. 

Full set of King race bearings.

New crank sprocket & key .

Although the previous mahle pistons had fresh scratches on them , they were recent and nothing to do with the pistons themselves and looking more like debris in the chamber being the cause of the marks.  So I'm still impressed with the quality and it looks like they've widened the bore of the piston ring oil feeds compared to the ones I bought 8 years ago .

Dropped the cdb , 2.5 crank ,king bearings and pistons off at the engineers.  Hopefully he'll fit me in within a fortnight to complete the thrust conversion and 93mm overbore 🤞

Had another parcel turn up yesterday with the arashi upgraded ball bearing 20g core 😊 seems to spin much more freely than the journal core .

Screenshot_20200312-224754_Gallery.thumb.jpg.b057313cdda6f145b8279ed431fec4d4.jpg

On the journal core 20g they recommend a 11 blade hotside wheel , as this aids spool but looses a bit at top end . The ball bearing core has a 9blade hotside wheel to flow better at top end .

Screenshot_20200312-224813_Gallery.thumb.jpg.df27f7688379874f0154c69936c6b53d.jpg

Got a few things to do , "de threebond" the sump , disassemble, check ,clean and reassemble the rcm oil pump  , then a few bits of ally to polish and bits to paint , to keep me busy .

But I can't wait to get stuck in with the build and see what this arashi uprated core is like

Still keep an eye on this thread Savage 5 years later!

 

Great work Sir. Hope all is well 👍

Lol , think I should've called it something like ...."a few pics of my never ending project " 😊

I'm all good thanks fella , considering the current situation with the virus 😷

Hope you n yours are well and keeping your distance from everyone else. 

I'm self employed and lucky enough to have at least 2 month's work converting a couple of ww2 office's on a disused air field,  there's only 2 other people I see every day .So social distance isn't getting in the way of work but works getting in the way of my scooby stuff 🙄

The over bore is done and hopefully pat Seager will have the thrust conversion and light deck clean done this week. 

Seeing as the pubs are shut , I spent most of yesterday cleaning the bay with a toothbrush to keep myself occupied 🤪

Not exactly filthy in the first place but it looks good for a 26yr old car .

Still got the 6 speed bellhousing and sub frame to clean , then I'll probably prep and paint the cam covers  .

It's only day one of uk lockdown and I'm starting to run out scooby things to do 😏

The wife is chasing me around waving a list of "diy jobs ,I've been putting off for ages " 🙁

so although I originally wanted to get a few things powdercoated, I've found some hi temp enamel paint and made a start on painting the cam covers. 

Screenshot_20200324-112006_Gallery.thumb.jpg.38f5d863543d1643b326cfa3a2cf75b7.jpg

Not the finish I wanted but better than making a start on the diy list lol .

On a plus note , pat Seager does a lot of one off's and makes stuff that is out of production now .he has a few bits to make for a london power station, that can't be imported atm , so is currently still working as a "necessity business " .

 

Which means He seems to think that my block will still be done this week , not all heroes wear capes 😊

Well just over halfway through the first week of uk lockdown and living with 3 female's is starting to do my nut in .

So big thanks to Pat Seager for making a slight detour on the way home and dropping the overbored and thrust converted cdb ,2.5 crank and bearings :backofnet:😊

Screenshot_20200326-142720_Gallery.thumb.jpg.92e04a9aa46432c27a0c70ff9abca4f5.jpgScreenshot_20200326-142707_Gallery.thumb.jpg.28942d8014ab4b569148a37dc6f2a9f1.jpg

It's my birthday tomorrow,  so might make a start then pending on how early I start drinking 🤔

But at least for the next 2 weeks I now have something scooby to do 😎

Will you be soda blasting before assy?

If it was a pre planned build I might have considered soda or vapour blasting but seeing as it went from "just fit these better v4sti heads " to a 2.1 stroker 🙄

I doubt my "scooby fund " or marriage will stand much more expense atm 🤔

I've had to put my link g4+ ecu on hold for now 😏

I'm probably just gonna use ath ally etch primer and brush on hi temp block paint again , after all it lasted 8 years and 60k miles last time . Plus Bare ally furs up quite quickly ,so if I did get anything blasted I'd have to at least lacquer it anyways 😉

I see - think I will need to look at a clear lacquer myself 👍

I've been at home since Tuesday at the start of the uk lockdown ,so had a few (to many) beers at home on Friday celebrating my birthday and didn't do anything scooby till sunday 🙄 Screenshot_20200329-201825_Gallery.thumb.jpg.b7c5812ec2940d9069418be0db0e838b.jpg

Although most of the parts have been through the hotwash,  there's no such thing as being too clean prior to assembly. My teenage daughter's like to get involved so I put them to work cleaning parts , while I dried them with a heat gun 😊

I trust Pat's work but I will still dry build the mains with plastigauge, to triple check the crank clearances . I also want to check that the longer throw on the 2.5 crank hasn't caused the piston skirts to contact the grub screws ,that I used to delete the oil squirters 😉

Screenshot_20200329-173704_Gallery.thumb.jpg.efab4ab8ab444dc0cd5c1e34ad2d2847.jpg

At least with everything clean, dried and prepped , I'm ready to do the dry build , if all goes well , I might even get chance to gap the rings too

Well today didn't get off to a good start 
Unfortunately, a bit of miscommunication from me and lack of experience with boxer engines from my engineer, ment the tang hadn't been altered on the center bearing case . 
I had asked him to do it and even shown him which bearing type needed to be fitted into number 3 main (old centre thrust position) but that didn't get told to the other machinist  .
This ment he'd used the wrong bearing type in the center main ,when checking everything over after doing the thrust conversion, overbore and hone .
Wrong bearing in centre main looks like it fits fine as the bearing tang holds it central. Screenshot_20200330-232609_Gallery.thumb.jpg.d1098576e618373232801035bee7f430.jpg


But the thrust type 1, 3 ,5 have the tang in a different position and you can see it pushes the bearing off centre 

Screenshot_20200330-232624_Gallery.thumb.jpg.0a45914f13fd306424fbf340e766319d.jpg

After chatting to him , I decided dust of my old metal working tools to measure up , scribe and file the casings myself to fit the tangs. Luckily enough I still have a few decent needle files ,so took a measurement off no1 main (to the right in the pic) then masked and marked up no3 . 

Screenshot_20200330-232759_Gallery.thumb.jpg.38c37884bd91c86db196c63daa81c9cb.jpg
It doesn't look perfect but it's not bad and measures up spot on 

Screenshot_20200330-232819_Gallery.thumb.jpg.31684d2141822535b3eb6263a8056214.jpg

Correct bearing location tang now makes the bearing sit central  

Screenshot_20200330-232834_Gallery.thumb.jpg.1418890c8cdf08334d70f27608f44da3.jpg

So that ate up a lot of my time  but I did still manage to check for piston skirt to oil squirter delete grub screw contact , plenty of room 

Screenshot_20200330-232905_Gallery.thumb.jpg.c2dd168639949586102665e6ec648cb2.jpg

A quick glance at deck height  .... not a wack a mole in sight (pistons don't poke out of the deck face ) Screenshot_20200330-232934_Gallery.thumb.jpg.760cb31de1e8d58d5a9e806f244010d0.jpg

And plastigauge the crank mains , which are all mid to high on standard limit 

Screenshot_20200330-233015_Gallery.thumb.jpg.bfaca54aa4af6223f5bc881905e678d7.jpg

I'll start tomorrow by gapping the rings and fitting them to each piston , then clean the crank ,bearings and bores before finally starting to assemble the bottom end

Found that I'd left a few of my better files around the farther in laws ,while working on his old skool 60's mini :oops: so progress has been painfully slow setting the ring gaps 
Screenshot_20200401-202327_Gallery.thumb.jpg.65aa4f884e20fe13b1ac0e46b1e4842c.jpg
For those who don't know , you do this by pushing the rings down squarely in the bore with a piston crown and measuring the gap with feelers gauges. 
Screenshot_20200401-202353_Gallery.thumb.jpg.8b2820809698d29f2e93f38b2aacf3dc.jpg

Then widen the gap , refit in the bore and measure again ... normally and again and again in my case :blush: as I always worry that I'll take too much off and make the gap too big . 

Screenshot_20200401-202424_Gallery.thumb.jpg.f6b8eaabaad9c7ba78bfe3ce4a72cf66.jpg
I also remembered I no longer own a piston ring compressor :oops: so had borrowed one of a mate for the last 2 builds , unfortunately he has no spleen and is on the high risk list for the virus :eek:
So I won't be popping round to see him anytime soon . The one I ordered off ebay this morning was dispatched this afternoon , so hopefully it will get here soon .

cleaned plastiguage off the crank and coated the king bearings in graphgen builders paste , then fitted those to the rods and end caps .

Screenshot_20200401-202502_Gallery.thumb.jpg.0e5dcc6094f2a4d4777f87f02d682936.jpg

coated the arp end cap bolts and torqued them down onto the crank 

Screenshot_20200401-202553_Gallery.thumb.jpg.25e640d32d81f6d2901f1b5b107474b4.jpg

Cleaned the bores in one bank and that's sat in a sealed box but will wait until the piston ring compressor is here before before fitting the crank into the block halves . As I don't want the case assembly left open (no pistons in the bores ) for too long ,even in doors and in the dry 😉
