Modding my car :)

So you guys all drive better looking cars with more usable power on tap do you? ;) Nice car op, out of interest what mpg do you get on those? My only experience of of Scoobs was I once went out as a passenger in my old boss's P1 Impreza. We were 4 up in the car and I still remember thinking it was neck rippingly quick in first and second. The 4WD just puts it all down. Amazing.

Yup, I have a blob eye WRX :p

(ok it's hardly modded but until his bits are fitted mine's got more power lol)

The car could have 1000bhp and people would still find it ugly, the amount of power it has doesn't come into that equation :) People aren't saying it's slow, just they don't like the looks which is fair enough.

I don't mind the spoiler, but I wasn't a huge fan of the bug eye WRX. The STi with the prodrive bumpers etc was better looking.

Surely you need to factor in a new fuel pump if your fitting a larger turbo?

Also what about the injectors in the WRX will they be able to handle that level of power as you don't want the engine running lean.

What is the VF35 turbo capable of been pushed too, could you push for 400+ if you did other mods around the car to support it. Will the car still be quite laggy with the VF35 or will it improve that with a good map?

330-350BHP should be very nice and will totally transform the car Id say 3rd gear upwards, will make it keep accelerating hard even way into three figures. :)
 
Nice power increase. Not knowing these cars I am genuinely surprised they only have 225 bhp to start with. Thought it was more.
 
Dude.. you still haven't told me who is mapping it? Plus you need a fuel pump and injectors for the VF35 turbo. It's the same turbo I have.. you will also need an intercooler. Did you buy a decat uppipe as well as the downpipe, centre cat and back 2 sections? Even for the remap on the standard turbo you need a fuel pump ,walboro preferably. And with an upgraded intercooler (top mount anyways) you will need the bigger scoop and undertray etc.

I feel like you've missed a few vital things here..have you even had the car checked properly for the poor running or just decided yourself about the downpipe leak causing the problems? Sorry.. but I'm just a bit dubious!

This.

Also what's the gearbox in the WRX? Is it the same as the STi, or is it a weaker one and gonna cry with the extra power and torque?
 
My old P1 had 400bhp and the list of items changed to get it there was nearly 2 A4 pages, surely there is more than an exhaust, turbo and re-map needed..? If so that is a very good performance gain to cost..
 
I think the gearbox on these is reasonably strong, enough to handle a modest power increase anyway.

Would think you'd almost definitely need the fuel pump and most likely injectors as a minimum.

Stock WRX intercooler will also be a bit limiting I'd have thought.

Still tempted to get mine ecutekd to finish off the DIY PPP thing, got the backbox and Y pipe on it already. Wouldn't go much further though as I'd just sell it and get an STi.

Gotta admit I was surprised when the garage Lee took it to said his poor running was due to a leaking downpipe, to me it just don't add up, would a leaking downpipe cause such vast power losses, surely it would just make it sound like a tank but not make it feel like it had lost 100BHP.

Again agree with what your saying a bigger turbo normally means injectors, fuel pump at least and as you've confirmed those are required plus an intercooler.

From what I know walbro 255 pump can be had £70-£110 so shop around, the injectors I'd take a stab at £200-£300 and an intercool well about £400ish so plus all the other bits, well over 1k, but if such mods do fix the car and the result is close to 350 horses it will certainly go.

But I agree there is no chance of 335BHP with those parts on the OPs list, or certainly not for long before something goes BANG.
 
Where did you take it to get it checked out of interest? Gearbox is ok..ish at 330bhp and similar torque. Weak at anything above that. Clutch will take it for a bit.. there's a few factors to consider..
 
I have taken it to Pole Position in Wolverhampton, they specialise in Scoobys.

Chris from JDM Motorsport advised that the clutch in mine should be good for 330 bhp. I know that a better fuel pump is needed, I can get a brand new walbro one for £96, already researched this. Injectors are something I need to research more, but I have already read that the "pink" injectors are the best for my car :)

Scoobydoo, maybe I didn't paint the full picture with the extra's I need, as I haven't fully researched it yet.

Apparently the mechanical fault of the leaking pipe is causing an electrical fault on the o2 sensors reading badly and thus having a knock on effect on the fuel mix, thus causing lack of power.

The garage also said it common when the downpipe goes for the CAT to move around causing a minor blockage thus not letting the engine breathe properly, the garage did a compression test to ensure the pistons were not damaged as a result - they are fine, but they recommmended to take it easy till exhasut is fitted, hence why I have not broken 3k rmp since. Godd job the new exhaust is being delivered today :)
