Hi my 05sti is running 414bhp i think its time for fmic but what one hdi or japspeed and do any of them give you a bit more power with a map tweek

 

HDi would be my choice and with the lower charge temps you may see a little more power from a map tweak

 

i got the jap speed one for 200 quid. on my 05 sti running 430 heard they good for 500 mark.

 

Yeah but they haven't had any in stock for ages. I got one from Ebay and my mate that has a Japspeed one said the kit I got was identical to the Japspeed!!

 

Ive ran a newage hybrid core to 540bhp and It was spot on charge temp wise, only changed as I wanted more power and got a hyperflow monster at a good price

 

As above we run Japspeed core and has been spot on at 490bhp,above that I would suspect will not cope,just due core is smaller than HDI

HDi, just work and are reasonably priced.

As for more power: well the principle reason is to get the charge temps down, but yes, after you've had it mapped it's unusual not to get a bit more poke!

You will need it mapped after getting it fitted: take it very easy until then!

 

Ok thanks guys never drive my car after parts fitted till andy f maps it

 

Was that the old core Banny? Old one was rather limited unfortunately and it took a while for them to bring one out for the newage models that matched the kits for the classic.

New Hybrid core (X0-1R) for newage is tube and fin, exceeding the original GT Spec Core on the classic and on par with the GT2 Spec core that has been used well in excess of 700bhp.
