My M10 turbo setup, what boost and what power???
Hi, I'm almost ready to start my BMW 2002 turbo project, and when I mean start, I mean start assembling/tuning, as I have been colecting the required parts for two years now.
My setup is the following...
-BMW M10 block, stock bottom end
-stock E12 euro head
-Stock compression ratio (8,5 , 8,3 ?)
-2002 turbo head gasket
-new water pump
-new oil pump
-new timing chain/tensioner
-E30 bigger aluminum radiator
-Garret T03 .48 turbine, 50 trim, 0.4 bar wastegate from a Saab 9000turbo
-Megasquirtn'Spark programable Fuel injection/spark controler
-Bosch 315 cc(30lb) injectors
-custom intake manifold
-60 mm Porsche 944s throttle body with TPS
-Intercooler (the only part I'm still looking for)
This will be a street setup, think it will be ok with 0.4 bar (the Saab had 185hp from 2.0L) but how much more can I go up in boost reliably? And what kind of power should I get?
Re: My M10 turbo setup, what boost and what power?
Saab isn't getting 185hp from 0.4 bar, try 0.85 bar The 0.4bar is <i>base</i> boost, the APC system can <i>lower</i> the boost to 0.4 but normally runs 0.85bar. If you don't mind tapping the block for a knock sensor you could adapt the APC from a Saab 900 as an inexpensive electronic knock sensing boost controller (A number of Volvo folk have done this, I don't know of an BMWs).
The level of power and boost depend on the overall configuration. With a T03 50-trim you should be able to stay in the reasonable area of the compressor map into the 250-300hp range, the 30# injectors should be good to 220-240hp (0.5-0.55#/hp, a Rising Rate Fuel Pressure Regulator [RRFPR] would bump that up) which depending on the specifics of the engine could be anywhere from .7-1.4bar [assuming somewhere in the 100-130hp range for the unboosted engine]. Start low and tune up but 200hp should be easy and quite safe to achieve.
I've been runnig an APC system on my car >>>
how hard to install???? Instructions?? thanks
