hey great write up and pictures! i am using this thread for my own install, but i am having problems with removing my up pipe bolts. i have heated them and pb blasted them and i cannot seem to loosen them at all, also i am having issues with the down pipe because i removed all bolts and nuts and un hooked the exhaust and the down pipe still refuses to come off the turbo..... and yes I'm positive all bolts and nuts have been removed. any help would be greatly appreciated!

robbyh · 11-12-2012, 11:00 PM

Use a piece of pipe or longer ratchet to get more torque on the bolts that will break them free

And for the dp try a rubber mallet. Few wacks will pop the seal it has to the exhaust housing

Looks sweet hope it runs well

Smallhashbrown · 02-25-2013, 11:29 PM

How's the car holding up today with the turbo? I just bought vf48 and DW 565cc injectors. Going to use your write up for sure

txl146 · 02-25-2013, 11:49 PM

Car's holding up great @ 301whp w/ original 5 speed transmission.

Good luck with the install.

Thanks man! How many miles are you up to these days? I'm worried about my glassbox... What clutch you running?

txl146 · 02-26-2013, 04:31 PM

105k miles, roughly about 30k miles @ >280whp and 60k miles @ >220whp. You'd better stick with OEM clutch to be safe, which is what I have.

Awesome! Thanks for the write up and info!

SammyJankis · 04-03-2013, 08:53 AM

I just got my vf34 and pink injectors and I'm swapping everything onto my 03 wrx in early May. I was wondering if anyone could provide a list of small items that it would be beneficial to go ahead and replace while I have the turbo off. Hoses, clamps, etc. I want to make sure I get everything ordered/bought before I start the swap.

Also, how necessary is upgrading the turbo inlet hose? Is the Perrin worth the money or is the stock unit fine?

This write-up is awesome. Gave me the confidence to go ahead with the swap. Thanks!

Upgrading the inlet is not necessary...however, the stock one becomes very brittle with age and if it cracks during the install you'll be SOL if you don't have a replacement on hand (stock or aftermarket). Personally, if I'm gonna end up replacing the inlet anyways I would rather spend a little bit more money on an aftermarket one.

Would anyone recommend a jdm turbo?

What do you think a VF34 is?

my '03 only has 50k miles...any way i can judge how weak the stock inlet might be?

there are lots of options for a turbo upgrade. depends on what model year your car is, STI or WRX, how much you wanna spend, how fast you want it to be, etc...the vf34 is a JDM turbo but a vf39 from an American market car would be fine as well. theres a great turbo sticky on here somewhere that explains all turbos for these little rockets. good luck.

Unfortunately it's a roll of the dice kinda thing - if it's a DD I wouldn't risk it without a new inlet handy. If you can afford a few down days while you order a new one, then I don't see a problem with trying to save $$ and reuse the stock one.

rgr that. i have an alternate vehicle but im doing the injectors and fuel pump at the same time and then trying to drive to my tuner an hour away for some pro dyno time. might just order the part and if i dont need it return it....kinda dick i know but whatev

txl146 · 04-03-2013, 05:05 PM

I'd recommend replacing stock inlet with upgraded hose (seen many stock hoses leak). I have the latest version from Perrin and found it to be very good in terms of fitment and quality. With stock hose off, it only took me 30 minutes to install the hose.

It's very important to spray hose with soapy water during install, which will make putting hose back much easier. I cut nipples off stock hose to make removal easier.

jhayesvw · 04-05-2013, 12:37 AM

I keep wondering if my car would be significantly quicker down low (3000-5000rpms) if I just went to some pink injectors and vf34.

I have a blouch td05 16gxt, STI TMIC, 3" cobb turbo back,grimmspeed uppipe, grimmspeed 3 port EBC, walbro in tank, FIC 1100cc injectors, K&N intake, 91 octane protune and E85 protune.
The problem is that I dont want to run E85 as its very inconvenient for me. So the 1100cc injectors are probably overkill and may be possibly costing me low end HP (I think).

So my question is where do you get boost to start and where do you get the full 16psi.
Your HP numbers are as high as I would want. I havent even dyno'd mine.
If my turbo is comparable to the vf34 and 39 then perhaps just the injectors should be changed out and retune?
