would a hiff 44 turbo carb be ok on a stage 1 inlet manifold

[Leonard]

it should be, but the flanges maybe a different thickness to the metro exhaust manifold

[blister]

well will have to hope i guess how much bhp would i expect from a stage one 998 turbo? with race clutch? full maniflow system?

[Leonard]

depends how much boost you want to run, what head you are using, what cam you use etc. 80-90bhp on standard metro turbo boost at a very rough guess

[blister]

998 with standard head engine from b reg mini city E no cam change etc

[blister]

and i understand i cant run to much psi the t2 is max about 12 psi i think and i was going to run about 6psi and have a bleed valve to make it 12

[Leonard]

prob about 80 on 6psi then, but with a shed load of torque!

[blister]

ok much love

well i got the turbo atm and it has a whole in the acuator i got my boost gauge and i am on look out for carb and manifolds and just need to bolt it on and am i right on thinking that i run my radiator pipes into the turbo plus a oil feed?

The R5 spec T2 is efficient beyond 12psi. It's good up to around 16psi, & 20psi at a stretch with a good intercooler.

oh really i read differently thats brilliaint was plannin on using a ebay custom one large size same size as the front grill

I disagree phil, do you have a T2 comp map? T 15 psi mine was poor and the map canfirms this.

I think 80bhp is very optermistic with a standard head and cam with 6psi, more like 65bhp IMO.

And if you are planning on using the MG manifold then tou need the turbo inlet as no others fit.

All i have is seat of the pants & time on the rolling road. Mine certainly produced power up to 16psi on the rollers, with an increase of 44hp from 10psi to 16psi. On the road with better charge temps you can feel a difference from 16 to 20psi though the charge temps do start to climb so efficiency is dropping off quickly after 16 really.
