Modding my car :)

Basically you are fitting all STI parts into your WRX. You should seriously consider just buying an STI. You can pick up bugeye STI's for very little money, and if fitted with the PPP kit it will be a massive improvement over your WRX.

That would be my feeling. I had my WRX for nine months and then traded up to the current STI when I realised what a bag of worms modding the WRX was going to be. Be aware that 335bhp, if you get it, is near the limit for both engine and gearbox: expect one or either to give way on more or less spectacular fashion within a year or two. They might not, but there's a fair probability that the might.

I also agree with ScoobyDoo69 - and you (Ace Modder) seems to be aware - that a load of supporting mods are required: that's a big power jump for a WRX, which really isn't designed for it. My first feeling is: just replace the whole exhaust system from the turbo back and then get it looked at again. If the problem has deffo gone away, then plan the mods carefully.

If you're going to do this then just buy the STI in the first place. Seriously, scoobynet and all the other many, many forums are filled with posts like this.

Save yourself the heartache, worry, trepidation that it might all go bang and just buy the car you should have bought in the first place.
 
Don't get me wrong, there is definitely nothing wrong with modding a WRX, you do get to a point where it's just stupid expensive to go further. Just like in a classic. But I wouldn't say don't mod one because of that.

All I'm trying to get at is that it appeared as though Lee thought he could just slap on a VF35 and get it mapped.

Having just seen a picture of the exhaust Lee has aquired, I would still say he needs the following:

Walboro fuel pump
Decat up pipe
Remap

This is before changing the turbo. By all means buy the VF35 but hold fire fitting it for a bit. You want to make sure that with all the above mods that your car is actually ok and there isn't something that needs replacing, e.g clutch etc.

When you do come to fitting the VF35, get yourself a set of STi injectors (the pinks ones like you said) and get it mapped again. The problem with changing your injectors is that it's not a cheap job to pay someone to do, and ideally (well pretty much a MUST) is that you get it mapped straight away - like the same day. As different injectors obviously run completely differently.

Don't take any of what I'm saying as a stab or laying into you btw Lee, I just want to make sure you don't end up wasting a bag of money only to find there's something else wrong - or to have your expecations too high of what you can achieve for a certain price.

P.S - I would definitely definitely say change the up pipe, as I have seen the cat melt in these when they get mapped.. you can just buy an STi up pipe as they don't have the cat in them and are made of cast iron like the manifold, saves the expense of a stainless steel jobby.
 
I'm being a hyporcrit a bit as I used to mod but thats why i'm going to say it, dont waste your money and just get the faster car, breathing mods are ok but changing turbos and injectors etc etc etc, its just an expensive ball ache

It's not all that expensive though. With the mods I suggested, pre turbo replacement that is, the WRX will most definitely be faster (straight line) than the STi with similar power due to the difference in weight (circa 100kg), and response gained by decatting etc.

A sensibly modified WRX is a great car. It's when you stop being sensible that the WRX no longer makes sense and an STi is required.
 
FYI - my old WRX with just a decat exhaust system and no remap. The car had me and my brother in, and also had my 40+kg subwoofer package in the boot.


The car also ran a 13.2 @ 102mph at Santa Pod. The difference an exhaust system makes to a WRX is well worth it. Hence with a remap, Lee may be comfortable with it is it is then.

I just dont see those mods as sensible if you're paying someone else to do it

He's fitting the exhaust himself I believe. And it's not like he can map the car himself..

Are you sure STI pinks are necessary? I thought the bugeye wrx's run 440cc injectors which should be good for 340bhp with an adjustable fpr. My classic has 440cc injectors and I'm planning to fit my vf35 without changing them. I agree with the fuel pump though that will be essential and I should think the clutch will last little to no time with a vf35 fitted.
 
Like I say breathing mods are all good, especially if you're fitting them yourself, remap to get the benefit of those mods as and when you can afford it, also fine. But the other stuff just seems a bit daft when you could sell up, buy the quicker base car and then do the breathing mods to that with the added bonus of reliability
 
With an FPR you can yes, but it is not as easy I would say ? I personally would rather change the injectors first. Either way works :) But you definitely need more fuel getting in there!

dont you lose a lot of the scooby 'sound' when you change the DP? or is that just equal length?

I know a guy who was miffed after he did that and lost his burble hehe

Those are the worst headlights I've seen!

Disagree totally I think those headlights look good. Really set off the front of the car
 
You guys make me laugh. You would much rather someone spent an extra £5k to buy a new car, as opposed to spending £1k on some very worthwhile mode, which he could reuse once he finally has the funds and is in the position to buy a nice STi. Those few mods would make his car much nicer for now.
 
Or he could take that grand, sell his WRX, chuck on a few extra hundred quid and end up with a better base to start modifying things.
