v1/2 ej20g block limits
Gents,
I have a v2 wrx ra engine in my classic, and I am wondering what the proven limits in terms of bhp are of this engine. I'm speaking mechanical only, the tuning I have is only knock capable at silly conditions such as 5th gear at 30mph wot
Over here, on the identical tuning via rom, guys hit 292,297,301 to the wheels, or roughly 375bhp.
This is with the td0516g, a proper slanty, and a 7300 rev limit. As well as 1.25 bar.
Just concerned with the capacity before things go BOOM

If its a cdb then its good for silly power, saying that even the odb blocks can do over 500bhp easily, its the internals you have to worry about, those are chocolate tbh 
start pushing your luck at over 330bhp.

mechanically the open deck standard turbo engines can be tuned to 400 reliably with a decent rev limit with meth/water injection have this on a super reliable source
on standard equipment though eg a slanty etc id say youd be hard pushed to extract even 300 to 320 honestly

SAE Mustang brand Dynomometers.
It has been done over and over.
Anyway, I got one of the few odd ducks that did not get cdb for a sedan wrx ra. The rods are the weakest I assume? Quickly followed by the forged pistons?

again, I think our bhps mean different. when a yank says bhp, we are talking at the engine/block/brakes
wheel horse is what we attribute to the power hitting the ground

Hi there
if its OBD i would say you will invest money to better pistons(Wiseco,CP,Cosworth etc.) and forged rods,ACL racing bearing set and you should be all right at 400-500bhp(at 500bhp i would say you will need at least 12mm head studs)
CDB are generally better engine for start tuning,with right spec you will not have problems at 600bhp.
About the RR figures,this has been several times covered,in USA is mostly used SAE,in EU are used DIN(mostly)
