my mate has just bought a ver 3sti and i have a ver 2sti so i want to know what is the differance and is his going to be faster the swine
thanks matt

 

Amongst other things the V.3 will have a front entry turbo (90 degree on yours) 440cc injectors (380cc on yours) larger TMIC, probably better internals as V.2's are a grey area, some hove forged pistons, some don't. The version 3 comes with the molybdenum coated low-friction pistons (I think!)

Your V.2 Sti is rated at 275bhp, his 280bhp, would be about the same I think in the real world.


Somebody will be along soon if I have forgotten anything!

 

so he will have bigger injectors and a larger intercooler that would all help the performance,his ecu can be mapped aswell cant it

 

No the only remappable are the 1999-2000 cars STi3/4 wernt mappable athough power engineering did get round this with a piggy back device

 

Basically, he has a better base car to tune from. For you, tou'd need to upgrade your injectors, fuelling system and TMIC to get over 300bhp safely with an ECU.

He'd just need a fuel pump, fuel pressure reg and the ECU.

 

I wouldn't agree with that. My STi Ra ver2 makes 308bhp @ 1 Bar with only a full decat exhaust, induction kit, boost controller.

The ver2 also has the advantage of having a TD05 turbo as std.

 

thought all scoobs mappable using apexi fc commander...??? been saving up !!! for mine...!

 

If you wanted to go above that you'd need to upgrade your injectors and intercooler. A V.3 would already have the capability to go higher just through an ECU.

 

i have full decat ex ,kn induction kit,walbro fuel pump,

i have a z4 in my car and it will boost up to about 0.9/1 bar, if i put a electronic boost control on my car will i be able to raise boost just below fuel cut,would it make much differance

 

A V.2 map sensor only reads to 1.2 bar, this means you would only be able to go to around 1.1 bar.

A cheaper way would be to get a Dawes Device and adjust it according to your boost gauge (if you have one).

 

i bought a cheap one from ebay and i could not get it to work,i think the spring was to weak,it was not a dawes but a similiar thing, i have not got any knock link or afr meter,would it be ok to fit one and what sort of boost do you think i could go to
thanks matt

 

Actually, Power Engineering won't tough the sti 3/4 with a piggy back chip. I know, because they wouldn't do mine. Something to do with the sti3/4 having a weaker engine! Or could it be that they had one blow up on the rollers once??

 

my mate picks his up 2mow,ive not seen it yet but he says that it is standard and only just been imported, so any advice on it would be good

 

The STI 3 has a higher revving stronger engine. His will redline at 8,250 rpm as oppossed to yours at 7,500rpm. The reason mapping is difficult on the version 3 is that they only used that chip for around a year and no-one can be bothered doing all the work mapping them, when they will not have much future demand.

Now we are a few months on, how do the 2 compare, does he beat yours?

 

he had to spend £1200 pound on his as soon as he bought it
it is bloody quick,
havnt had a race with him yet would be close,but ive got a z4 in mine witch wont boost as much as a proper sti ecu
matt

 

i was referring to standard ecu's aftermarket units like apexi are fully mapable

 

just trying to contribute bud... (wrxtreme 96 makes mental note to read post more carefully !!!)
Anyways thought my contribution had been ignored..

 

As said above, Apexi ( and other aftermarket ECUs - Pectel, Autronic, GEMS etc. ) are fully remappable.

1999 IIRC, certainly 2000 on are ECUTek mappable, 1992-1996 ECU's ( std ) can de modified by a Scooby ECU or other Japan / Australia add on chip devices, or some Uk companies like IIRC Scoobyclinic and Powerstation/power engineering can do them too, and 1997 cars are hard to do although again some companies can do those too for a fee...
