T4 will be a waste of time if you cant get the engine to be able to flow the amount of air the t4 will be supplying,are you on a standard head and cams?

crumpet

well i havent bought one yet, Il be after over 350bhp anyway, what turbo is good for 400+? t34's are only good for 380 arnt they?

il have b14 inlet and std bd8 exhaust cam iirc?

i would personally go for a T34.63 you should see a gen 370-380 bhp fit either black Siemens (55 ones will be fine!)or bosh light blues(400's) or greys (403's)although i think if u have a 2wd inlet plenum she will struggle to cope with this flow rate!

i presume you have the other bits in peices ready?like grp a fuel pump and rewire (for peice of mind!)500 type intercooler etc

crumpet

il have a 044 pump mate and rewire, 403 injectors, Wrc headgasket,sweedish plenum, rs500 cooler, 2wd manifold, -34 actuator, 3" exhaust, 3 bar map etc etc and the chip sorted my stu at msd...

What about cams? what should i get?

I like the sound of a solid 370-380bhp, do you think my internals will take this? and what clutch do you recommend? cheeRS!!

mechanic28

standard cams mate!standard engine is good health will handle this power mate!

Clutch i would either go for a alcon/ap 6 paddle with heavy duty cover!not that different from a standard cltuch tbh mate

They will run 380 with ease no need to change internals or cams, but as said go for a paddle clutch.

Also check your fuel pump and fan looms if not already rewired.
