Hi there, first let me say thank you for being part of this forum. Now I just bought a 95 wrx import with the 260bhp engine ( I think?) and would like to know if possible how much bhp I have as I have a few mods so mods are: fmic, apex induction with hks mushroom filter, straight trougth decat exhaust and td05 20g turbo so what you guys think about the bhp surely is got to be 280bhp?? It does go very well

 

Depends if its been mapped or not, might be anywhere from 240-300

 

I'm going to bet it's running this map...

 

 

Thanks mate well it has a standard z4 ecu I'm not sure if is mapped but I have been in a few fast cars and this really pulls is doing like 16 psi boost and I looked on Subaru specs typed my engine full engine code and it says is 260bhp standard but not sure how accurate is this Subaru site that I went on

 

i doubt it, that looks a very detailed map.....

 

It's running a 20g (not a 16g???) on a standard map?

 

It might go well, but it might also go bang without correct mapping.
The mods all increase air flow (turbo, filter and exhaust) but still standard injectors, so will be running lean, poss detting

Get it on a rolling road for a health check, it could save you a lot of money

it could be 280ish bhp, but with correct mapping it could be 340bhp

 

thanks for the reply and sorry for the long reply yh is a standard map I'm sure I say this because is fuel cuting at like 5 or 6000 rpm I will get it mapped also I forgot to mention that it has a 2005 sti bottom end which I been told that is a lot stronger then the old block so you guys think a map will sort it out?? I have the car off the road now to kind off restore it so will be done soon.

 

yeah its a tdo5 20g they guy I bought the car off didn't have a clue about what he was doing so it's off the road now to get it spot on body work and engine.

 

Not the worse ive seen, Saw a guy at a rolling road day with a standard-ish UK turbo 2000 running a GT30 turbo on standard ecu(no remap),his run had to be aborted and the dyno operator refused to test it a 2nd time!!!

 

Dont forget there are a lot of cheap copies of the TD05 20g, just type it in on Ebay to see the cheap Chinese copies, A genuine one from Andy Forrest or Harvey Smith will make 380bhp with the right cooling/fueling/mapping!!
