Also depends on your budget. Lots of pistons and rods out there. Some suppliers charge a fortune as they pistons/rods will take more abuse than you need.

Also budget for brakes/clutch and if running wrx, get ready for gearbox

25 August 2008, 16:02

hi money its a 95 wrx my gearbox needs changing anyway so thats what got me thinking lol. iam going to buy all the bits a little at a time or just use the plastic lol. so my budget is what ever it costs if that makes any sense. ive just bought some red stuff pads and drilled discs ive yet to fit them but if there no good i could always upgrade them at a late date. but the car already has 4 pots on not the billet type did these come standard on a wrx or do you no if they are off another version.

The 4pots are ok. I think when you start pushing or near 400bhp you will want to change to maybe brembo 4pots (assuming your 4pots are from 98-00 scoob) or better 6pots like ap racing setup.

Gearbox will last but i found with mine at 400bhp that after a few launches, 2nd gear started to whine so will eventually go.

Plastic is a dangerous thing! haha

You would need a mapable ecu. I used motec which was good but switched to Autronic which was quality

I have a 380 BHP STi Classic, my spec as follows:

Forged Wossner pistons and standard STi rods
850cc Injectors
FMIC
Td05 18G
Apexi Power FC mapped By Andy F

Striaght through exhaust, turbo back.
Fuel pressure reg

I would also add to this:

Headers
Maybe a larger turbo

We have just started selling built forged 2.1 short motors using your existing block for £1700 inc vat...
With your CDB you would end up with a very strong engine capable of far more than your intended output...
I would recommend raising the inlet manifold and converting to a front entry MD turbo , MD555 or MD321H ...
For a sub 500hp build a cheap flea bay Autobahn intercooler will do you fine saving a few hundred quid towards your ecu..
The SimTek ecu would be my choice (£995 supplied fitted and mapped inc vat) and allow a bit extra to have the map sensor upgraded for a 3 bar unit , usually £75 ish...
740cc Nismo or Power Enterprise injectors would suit , avoid the cheap Venom injectors as they can be very poorly flow matched...
As for the gearbox , 6 speed boxes seem to be appearing second hand more and more and work very well...

Definitely NOT worth the saving! The high quality hybrid is shy of 300 squid now, is a proven quality product with decent ancillaries etc.. that will not pose any fitting problems.

When having my hybrid fitted by an independent garage, they commented that they had installed several hybrids and Autobahn FMICs and the latter were significantly inferior in terms of both quality and ease of fitment, the labour costs incurred as a result of the latter would more than negate any saving you made buying the inferior product.

The hyrbid is one of those few tuning decisions that really is a "no brainer" IMHO. That comment is not intended as a dig at you Martyn, just testament to just how much I, and many others, rate this excellent value for money piece of kit!

No offence taken NS , and to answer you I agree that the hybrid is a very good piece of kit...
That said I have seen some very good results on the Autobahn kit , 500hp + in a few circumstances and the quality of fit isn't bad when done correctly ..
We have fitted loads of Autobahn kits over the last couple of years , the only one that posed any fitting issues was due to the car in question being damaged from a badly repaired accident ....
P.S. We are entirely independent on the intercooler front as we stock neither brand and have sold both on many occassions ....

Deep pockets for a reliable 400 & its a slippery slope when you get started.

So far I have acheived your target with this:
MD321T
2.5 SHORTBLOCK
WEISCO PISTONS
LATERALPERFORMANCE RODS
LATERALPERFORMANCE HEADERS
SIMTEK ECU
740 FLOW TESTED INJECTORS
3" FULL DECAT SYSTEM

with other odds & ends it has cost me about £9k this year.

Oh and 6-SPEED BOX & EXEDY PADDLE CLUTCH to be fitted.

BUT WHAT FUN

398bhp on a 96 wagon with a forged 2 litre, 20g turbo, 6 speed box, 740cc injectors and ESL Live as a more affordable option.
