I think my WRX is a V2?? If so i think i have a Closed deck block. Im only going on the research i have done. V3, V4, V5 are open.

Correct me if im wrong

 

is it a wrx or and sti. there is a vast difference. standard jap import wrx are open deck blocks mate, i used to have a 95 wrx jap import.

 

Yeah its a Jap WRX. What are the differences with the WRX blocks and STI blocks?

 

look at the pictures in the link mate

 

It doesnt matter what type of engine block you have, open or closed on classics, it just depends what your putting in there followed by what gearbox/gearset/clutch/brakes etc etc etc your going to put with it so the car wont tear itself apart

tony im just wondering whats the limit bhp wise of a open deck block has mine is all forged internal and is an open deck running 390 now ive been a bit worried to push any further as i was under the impression that open deck blocks didnt like runnign more than 400bhp is this true

 

People have run over 500bhp on the open deck blocks with no issues, think harvey runs an open deck with about 480bhp, most people dont want more than 400bhp anyway, thats more than enough for the road

thats ok then as i was think later in the year to try an hit around 430 mark with another turbo as my 20g is good but there is better out there just not sure what to go for to hit around that mark an i dont want it to be to much turbo lag, i need to get some bigger injectors as well, i have been toying with the idea of having a twin scroll set up running around the same as what i have now but just quicker on the up take
