Modding

[aaron_mckay]

Guys would appreciate a bit of help. Thinking of going down modding route with a scoob for fast road / track use.

Currently have a P1 which I know people have gotten to circa 400bhp on stock internals, but I currently have it for sale and not sure I want to mod it.

 Been looking at uk Turbo 2000 or early JDM STI (v2 / 3).

Question is if I go for the uk or JDM StI what will I have to do to get to 400? Is it going to require a rebuilt with stronger internals?

Off top of my head and limited knowledge I know i'm looking at:

 FMIC / Bigger Turbo / 550c injectors / New clutch / Walboro fuel pump / decat exhaust / Remap

 
Have I missed any of the bigger things? Gonna be looking to do most of work myself ( completely new to this but keen to learn!)

 Thanks for help

First of all you need to decide what you want it to be like, track car, driven on the road only really to get to the track or road car with the odd track day. Also what sort of power delivery your after, lazy, torquey drive or revvy peaky power.

I know of a couple of early sti's that ran up to 400 on stock internals but iirc they didn't last long.

Car wise, if it's just a track toy then, depending on budget, i would go for an sti2 or 3 ra, but for road and track a sti2 or 3 etc.  To get 400 reliably i would get the engine rebuilt with forged internals.

Personally i'd get a 2ltr cdb with modded 2.5 crank as i like a revvy engine but a 2.5 bottom end is a cheaper option.

You'll also need to look at brakes and chassis mods to cope ( which i'm sure you knew).

The box would prob need seen to aswell.

Obviously there are loads of options open to you these are just a couple.

 

Good luck, it sounds like an interesting project.

Thanks Johnny appreciate the input! Need to decide before I spend monies on brakes which car i'm keeping!

Seen some lovely D2 8pot brakes on ebay would look mint on a white sti!

I know of at least 2 UK Turbo engines that got beyond 400hp with no problem and 1 early WRX RA engine that got 430hp.

All engines had stock internals.

Maybe 400 would be pushing the stock engine too far. Not afraid of the rebuild when it happens but at same time not actively looking to sprint towards it as fast as possible you know!

Maybe 350 - 370 might be a more realistic figure?

Gonna need to invest in some tools! This could get messy given my very little knowledge of car internals! Keen to learn though!

Cusco thanks for pm.
