stevotype_r

just wondering which is the best turbo to put on my 97 type r that will take around 400bhp as its got an ihi turbo on at the moment and the car is pushing 334bhp with the wrong fueling so bigger injectors,fuel pump and a new turbo on there way (just fitting exual length headers and new up pipe as well) also looking at fittinf an afm from a skyline which is 10 mm bigger than standard its a q45 i think which some tuners in japan are putting on there cars.

You will also need to consider intercooling to achieve 400bhp. I'd recommend a mimimum of an Sti7-9 top mount or a front mount. The Air flow meter on your car is not a restriction at this level but the std airbox may begin to be.
Regarding a turbo, the TD05-20G will make "around 400bhp" Results of 360-440bhp have been achieved depending on the spec and fuel octane.

Dare I suggest you look at the various threads on Projects, as it has all been detailed there.
I run an AndyF turbo with several supporting mods which resulted in a RR result of 407 x 340 engine.

AndyF TD05 20g
550cc injectors and walbro pump with SX regulator + parallel fuel line mod
Optimax with full dose of NF booster
Apexi Fc ECU with AndyF map
Engine breather mod
Gruppe S headers and flex up/pipe
3'' decat down pipe and system
Stock inlet tract/MAF with Green Cotton filter
Cold air from inner front wing, all air vents cut open to max air to inlet
Sti V8 TMIC

The engine is a stock Sti V3

Hope that helps you.
The car has a host of chassis mods to to enable the engine to be 'used' so to speak but stock brakes(!)

How much boost do you run, Graham?

The turbo can muster (iirc)

1.1 bar at 3500
1.4 @ 4000 through 6000
1.2 @ 6000 to 6.5
1.1 @ 6.5 ish on
I have seen a peak on the FC of 1.5 once (lovely cold day and 'caight' the turbo just right in third...wow!)
