Re: how much BOOST? (VR6'n)

I was told that a G60 motor was designed to handle 30 psi. As far as a stock set-up, it really depends on milage, PO, etc. Most will take a solid 15-18 w/minimal problems if tuned right.

Not completely true. The stock pistons are cast Mahle units, not forged. The motor is pretty bulletproof though.
Kinda of off topic, but if ya want a motor that is so bulletproof and durable that it is silly, go get yourself a classic Saab 900 turbo. I've spent at least as much time learning about and working on them as on g60 Corrados, and I never heard of ANY bottom end problems with the 900t motors. Where it seems like we get people in here from time to time talking about pistons with holes in them and shot rod bearings.

Hehe yeah both Sam and I are proof that these motors arent quite bullet proof....

Re: how much BOOST? (David L)

Yes, the gearboxes are very weak in the classic Saab 900's, bot the automatic boxes and the manual boxes. That's why I eventually got rid of my Saab, I didn't like the prospect of having to get the gearbox rebuilt. The turbos are perfect sized for the stock boost level (plus or minus 10 psi depending on the year and stuff) and up to about 15 psi. The turbos are well sized for those power levels, and they don't have much lag at all. Power comes on pretty smooth.

To give you an idea, I sold my 1987 900 Turbofor $2,800. Nice SPG's can go for around $4,000 or $5,000. More or less, they are about the same as a 60 Corrado, maybe a little cheaper. Similar maintenance and parts costs though, but the Saabs may have some slightly more expensive parts. They are definitely very fun cars. Very nice looking too, imho, and waaay more cargo and passenger room than a Corrado. they are about as tuneable as a g60 Corrado, but probably have a bit more potential - when I used to hang out on saabnet.com a lot, there were at a handful of people approaching the 250 whp level.
quote:[HR][/HR]Ditto on the Saabs. I've had two 9000t's and those cars fall apart around the engine. Sweet sleeper.[HR][/HR]​
If you wanted a nice Saab and didn't care much about body style, I'd say get a 9000t. Their drivelines are different due to a different engine layout, and they have stonger trannies, so you miss one of the big bad points of the 900t.
quote:[HR][/HR]A friend of mine have three Saab 900 T16 Aero...crazy guy[HR][/HR]​
FYI, The 900 Aero was known as the SPG in the US. The really early 900 turbos were 8 valve, I'd recommend staying away from them - they don't have the same potential. Later turbos were 16 valve. The SPG (or Aero) was a special model, with a nice body kit and wheels with three wide spokes. Later years of the SPG had a sportier suspension and a slightly different APC (the computer that controls the turbo) to give slightly more power.
You can start out tuning a 900t for literally pennies - soldering a couple buck worth of bits into the APC and adjusting the wastegate a bit can give you several pounds of additional boost. After that, the program of usual mods is very similar to what we do to g60's.
