Just a few quick questions for boosting a E36 328i (with warranty replacement block)
1, What is the very maximum safe boost on a totally standard engine (no spacer gasket)
2, Limit on standard fuel pump?
3, Oil Pressure at 2000RPM and 6000RPM?
4, Max RPM limit on stock valvetrain
I am building my own turbo kit for this car and with working out pressure ratios, volumetric efficiency (VE) and cubic feet per minute (CFM) I have got the perfect turbo to be at it's most efficient, well within RPM limits and without surge and/or choke from 10psi to 25psi based on an engine at 87% VE and a rev limit set at 6500.
Looking at possible power gains this could range between 320-550bhp - obviously this depends on modifications.
I will be using:
Custom tubular collected manifold (non-equal length) with a T3 flange
Honeywell Garrett Turbocharger
Stainless Steel Oil and Coolant lines
Custom downpipe to suit to OEM cats
Custom intercooler and alloy pipe work
Forge Recirc valve
Custom air intake
And I think that is about it
Let me know what you all think
