Not trying to prove anything. It was and still is a test to see what these engines can handle in standard trim and how long they will last. There have always been guestimates as to what the limit is for any given year of impreza. This was an update for people interested in whether the car was still running and what it has been used for.

You see a lot of posts from people asking "will it be reliable" when they are thinking of tuning. At least if they see this it will give them a good idea that say a 400bhp conversion should be bullit proof on a similar year car.[/QUOTE]
good points there

Surely longevity is dependant on engine to engine, amazing what you have done so far but I'm sure another engine would have give up long before.

Very true that I may just have a "good engine" but then I'm not suggesting that everyone should go out and try to run over 500bhp on their engine. If a good engine can ran at over 500bhp then no one should theoretically have trouble running 400bhp. Infact I would hazard a guess and say 450bhp should be pretty reliable.

You obviously do have a good engine. Everyone seems to be very 'soft' when it comes to tuning and ask mummy if an extra .01 bar of boost is OK.

Nice work!

RA Dunk

maybe everybody dosent want to blow their engines up by adding an extra 0.1 bar of boost though

^ x2 i will be keeping a close eye on this thread

stealthy55

is this a uk engine? if it is its even more impressive as there has been a lot of threads stating the jdm engine is much stronger than a uk, well done

IRC450STI

I was told the uk STI8 was the strongest & bullet proof

jamesgrd

standard unopened uk sti8 motor..... gearbox and ecu also original as a note

Pete

Is that the Bug version?? i,ve read and been told they hold the strongest internals..

CAN OF WORMS TIME...............

IRC450STI

not sure, ive herd that also

Pete

That,s this site for you.... Bug is the STI 7 anyway isn,t it??

IRC450STI

Anyway i was told that its the strongest sti8 engine you can get as standard, but how can you tell if its a JDM or UK version

GazTheHat

Has there been further development on the Anti-Lag?

Is the ALS now a switchable option that be offered to ECUTek cars?

jamesgrd

the cars a MY2003 UK sti blobeye

jamesgrd

Its switchable on the jdm sti's, uk's require an ecu wiring mod, no unfortunatly its not available for general use by ecutek dealers

stealthy55

james, now you have upped the ante where do you think the limits of the standard uk 2.0 is now? also do you think you will try for more on this car? cheers

jd5217

nice to see the bar being kept high with these standard motors.

jamesgrd

We are currently running the smallest .63 gt30r turbo exhaust housing, we have a .82 on the shelf we could try running or even a gt35r... but both these would have a negative effect on the drivability of the car and imho not really worth anything other than to try and get bigger power figures which misses the point of having a high powered road/track car! We are currently making 1bar of boost by 3500rpm(on the road) So personally I think on this setup the .63 gt30r is the acceptable limit!

The only other option we have looked seriously at doing is another vp109 racefuel map, as when the last one was done we ran slightly lower boost and had a leak on the uppipe(since corrected) and see what it runs then

ian.b

hummmm think you need lessons on the track, not being roude lol

jamesgrd

well if youve done better than 3rd place in a time attack club class final(running a standard turbo), 2nd fastest time scooby shootout handling(again standard turbo) and have a national B race liscence, then im all ears

wrxmad

great info. 507hp thats amazing!!! on standard engine and ecu. good work chaps now
wheres that garret gt 30 turbo and monster front mount )

Hi mate,

Is the car still going strong?

I'm running a md321h on my sti8 at the moment, I am about to purchase a S206 to replace it
