how much bhp
 

i have 1998 sti type r and have never had it on the dyno, would i be right in assuming it to be 300-320bhp with the mods on my car?

mapped apexi power fc
Walbro 255 fuel pump
full de-cat blitz nur spec exhaust
apexi induction kit

320 could be about right, it depends on what settings the apexi has been mapped to, and who mapped it :)

agree with above

I thought so too.. I was qouted 375bhp by the last owner but i am sure you cant get more than 350 on standard 440 injectors.. It also doesnt feel like 375bhp, my previous car was an 380 bhp evo 6 RS and the type r Feels nowhere near as fast as that..

also has in ihi turbo..
