998 spec and output
Turbo Mini Forums

Thought i might start this as im still at the planning stages of my 998 turbo build and i want to know how far to take it.

What have people on here got (spec) and what are they getting from them in terms of bannas and torque (name escapes me?)

Evo 2. As above with Audi TDi intercooler and 14 psi.

These will all be dynoed and the results published. So a stock 998 basically with just the parts changed that have to be to fit the turbo.

Second 998 build is underway.

Se7en spec 998 crank. Wedged, bladed.
Hillman imp pistons 71mm bore.
Custom cam grind.
Light rods, good rod bolts.
Ported 295.
T3.
Aiming for 150+ bhp.

There is a third small bore as well, 850 turbo.

MG metro cam.

Se7en spec 850 crank. (936cc).
Lightened rods.

Who knows what power I will get out of the 850? The RR will tell :)

I have had my 998 turbo dynoed and i am getting 155hp at 14psi of boost. This is with the water/meth injection running. I am currently running 8psi with the water/meth kicking in at 7psi

Caution !!!! Slippery when boosting

cripes with these 998's popping so much out and being 277cc down on the 1275 it makes me wonder if the extra 105cc's of the 1380 will make much difference

I am not using a T2 or T3 turbo. I am using an IHI RHB5 VI13 turbo of a 1600 Mazda 323. Also using the intercooler from this engine.
I will post the dyno sheet when I manage to find it in my mess.

Caution !!!! Slippery when boosting

I am using twin delortes 45. connected straight to the compressor side of the turbo. Therefore the turbo is compressing both fuel and air. Pics are up in the photo section under "Staggy's 996 Turbo"
