I've been running 326bhp on my classic for a couple of years now but am now in a position to increase this.

I already have a fully forged STI CDB engine, which has recently been given a clean bill of health, and am running Simtek ECU. I know I need to change my gearbox and clutch as well.

Just wondering which turbos you guys are using to achieve 500bhp and which injectors you would recommend.

Any advice would be much appreciated.

 

Andy Forest Page is yer best bet.

MDH range or Garrett I reckon, but ask the experts Andy is a top bloke.

Bolt on versions capable of 500bhp, SC50 Billet, SC54 Billet, Enginetuner S206 Billet, Enginetuner S215 Billet, Lateral MDX321V, Turbo Dynamics MDX555 and the Litchfield Twin Scroll LM500.
Few of the above are a dead cert to do 500bhp on straight pump fuel without head work and cams. If you want to be certain of making 500bhp + on pump fuel only, go for a rotated setup and a Billet 30R.

 

Thanks guys, that's a great help. Will do a bit of research on those turbos.

Tempted to go down the rotated route but have read this can be very costly due to the custom pipework required???

 

Hi, dont get too hung up on numbers , I am running a gt30 billet which was rated at 500-550 bhp , did I get the magic 500 bhp , eeerrr no ! Got 460 but it's already enough for the road as it is !! cheers Maz
