May 20, 201510 yr Hey guys. My 2003 blob currently has the following... TD04 Turbo. 255 Fuel pump Fully de-cat Exhaust (2.5") still has a cat in the up-pipe High flow panel filter and I am looking at getting ... Second hand VF35 Second hand Pink injectors Second hand De-cat Upipe. 1. is it okay to get these parts second hand? 2. is this a wise upgrade path to get to a fun level of power without having to compromise reliability? Please help me :) thank you !
May 20, 201510 yr Pretty typical up grade path, as long as you find decent second hand parts you'll be fine. brakes would be a good upgrade before though, on a wrx they aint great
May 20, 201510 yr Author How do i know if the turbo and injectors are good? They are from an STI that's being broke down, with around 67K Miles on
May 20, 201510 yr Or you can get much much more fun if you put money on handling. I had some test run with different Impreza`s so I can tell you the handling part really does make a difference ;) Upgrade the followings: ( yes I know this doesn`t sound as cool when you tell this the other guys as your engine is still stock but if you give them a ride with the below stuff installed they will think twice before they upgrade something in their cars :D ) Bushes to poly Engine mount/Transmission mount ( you can get this as a kit ) Strut braces Anti roll bars ( front, rear ) Coilovers Quick steering rack ( just for fanatics ) And you get a totally new car from the fun point of view and a top of that you can put a more powerful car to shame. If you get 50 or 80 BHP more you will enjoy that for less than 2 weeks and you are done ;) ( after that you probably will get used to it )
May 20, 201510 yr Author It has quite a few of the handling mods, plus the most important, good tires :) will do the rest at some point :) love the handling mods, its what really turns my passengers from "Subaru's arnt that quick" to "Stop the car! JESUS, you're not gonna make it !!! AAHHHH"...

May 20, 201510 yr Must admit I was looking to up my power to around 400 ( currently have 355) but think pound for pound I'll get more out of suspension upgrades such as mentioned above. If I can save enough on my next trip away for work I'll go for the tein coilovers possibly with the active pro edfc.
May 20, 201510 yr that's a normal list of upgrade parts and that's what I have had fitted to mine. I've been running 330bhp for 5 years and I haven't got bored with it. yes I'm used to it, but I don't think it needs to be any faster in a straight line. the std brakes are poor, I've got uprated discs and pads and new fluid, I've got some braided lines, but not got round to fitting them yet I agree with the handling upgrades, but it depends if you like going round corners really fast. since my accident I don't like going round corners fast :(
May 20, 201510 yr Author Thanks guys, what would I expect to pay for second hand pinks and vf34, found a guy wanting 120 for pinks and 380 for turbo. Also what would I expect to pay to have them fitted?
May 20, 201510 yr Does any internals need to be changed/uprated to run a vf34 turbo? What bhp would you be looking at with them engine upgrades?
May 20, 201510 yr its the gearbox thats the weak element, budget for a clutch as well, : 320mm Discs front and back minimum EBC greent stuff pads. Airfilter (Cone filter are best) Maffless remap Alcatek ecu or Simtek ( best overall ability to map the engine, Launch Control, Anti Lag, Maffless) some if not all can be added to ECUtek which is cheaper, however a standalone gives the option for mutiple maps, for meth, low boost, ETC Vf34 or VF30 ( make sure there is no play in the turbine, side to side and in and out,slight movement is normal as oil takes up some slack) Injectors, make sure rubbers arnt clean, if there cheap, they are so for a reason, get them ultrasonic cleaned and rebuilt will last ages and give best performance. Spark plugs, fresh set of Iridiums Exedy Pink Clutch Alloys front and rear Drop links, Or anti lift kit depending who you ask Coilovers , get these properly set up, height, toe in, and camber ( mines set up for fast road so has slight camber) DV ( vent to atmosphere, sounds good and gives swifter gear changes) STI Top mount Intercooler, good for 400bhp Metal Y pipes for top mount 3" Full decatted stainless exhaust Stainless Uppipe 280 Uprated fuel pump. With all the above and depending on your engine you should easily get over 350
May 22, 201510 yr Author That's a great guide and full of useful bits that I needed to know ..... now i just need to save a sh*t ton of money :') Thanks Ash!!!
May 22, 201510 yr I think the vf34 is a roller bearing turbo and are generally more expensive than the vf35
May 22, 201510 yr VF35 and VF34 are both based on a vf30. VF35 has a smaller exhaust side improving spool but slightly dropping peak, VF34 hs a roller bearing core but retains same exhaust. 35 and 34 have pretty much same spool but vf34 tends to have 10bhp ish more peak, cos of its better peak tends to hold its value better second hand as well as being bigger cost from new
May 28, 201510 yr Author Which feels faster ? Quicker spool, or an extra 10bhp top end... on our British roads?
May 28, 201510 yr Go for quicker spool, got to think will you be runing into 5-6k rev range on the road regularly or would you want it to get there faster without the need to be smashing it everwhere ?
May 28, 201510 yr tbh not huge amount of difference in but VF34 is the better turbo. Could always go for a SC36 billet, 360bhp and will outspool 35 and 34, but more money
May 28, 201510 yr Which feels faster ? Quicker spool, or an extra 10bhp top end... on our British roads? Lower spool = more midrange torque = not needing to redline it
May 30, 201510 yr Think the vf35 is based on the td05 16g (journal core ) here's a td05 16g on my brvs classic for comparison
May 31, 201510 yr Vf43 is a good,turbo newer than a 35 slightly bigger seen 370 plus on them has a slightly re designed exhaust housing etc
June 1, 201510 yr Author Seeing Dave's lovely car yesterday as persuaded me to upgrade :3! well that and being overtaken by a A45 AMG Merc ¬¬ if i had that turbo it would'nt have happened haha! Booked to be in, in 2 weeks from today :D
