Converting a cav gsi to a turbo
I have access to a turbo motor out of a cavalier - i was just wondering about the amount of work needed to transplant it into a 2wd cav gsi with regard converting it to 2wd etc
Any idea's or isnt it worth it.
Well I nearly bought a 2WD drive Cavalier Gsi that had been converted to a turbo. Just think... 204bhp... no 70bhp 4x4 losses. so 174bhp at the wheels, yummy.
Thing is I'd prefer the 4x4 version even with it's individuality. If I'm having a turbo cavvy I want the leather and the extra grip! Might make it look like a GSi though cos they look better!
Is this 70 BHP loss correct? Can someone who has Dyno'd the CavT answer this???
Richie will doubtless tell you a similar figure.
Yup, F28 gearbox is about 40bhp loss, rest of train is 30 ish.
Between 60 and 70BHP is the norm for the Cav/Calibra Turbo's
The 4WD GSi will be slightly less (say 45-55) as the F28 gearbox takes a whopping 40-45BHP as standard due to the heavy duty internals and other stuff.
The 2 dyno runs done 5 months apart show a 69BHP loss and a 67 BHP loss.
Ok, so a Gsi might have 130 BHP at the wheels and a Cav Turbo has 135BHP at the wheels but the turbo will still leave the GSi due to the sheer torque available to it.
A lot of ppl get too wrapped up in figures when practical "tests" can prove otherwise
Yeah but Richie... a 2WD turbo if it can get the power down has all that torque you torque about and less of it's bhp lost on that 4x4 gubbins. So won't it be faster in a straight line 1/4 mile situation?
We all know a standard cav GSi would die at the hands of a Cav turbo... all apart from when i raced that sick cally turbo But that's not the question and as u can see above. I'd have the 4x4 any day!
