Hey guys,
I just purchased a 1990 Sunbird GT with the 2.0L turbo and a 5 speed tranny.
Engine seems to be in great shape despite the milage (195,000 km's), and there are no oil leaks or blow by on the stock boost setting on that tiny turbo.
I was wondering, what are some good upgrades for these cars? Any good bolt on turbos, and do they use the standard T3 flange?
I have a couple Daytona Shelby's that I've upgraded, one for drag racing, and one for a daily driver.
My plan is to install a mandrel exhaust, straightpipe (help spool up), install intake (done... was super easy, gotta love K&N cone filters), mount an intercooler up front, and get a BOV to make sure there is no compressor surge...
It has pretty good power, has new clutch, brakes, etc, etc, and was very well maintained mechanically. What are the options for retuning, do these ECU's use Eproms? Or is there anyone that makes cals? I have an Eprom burner and eraser, could easily install a new chip if someone knows of a good programmer or program to use to write new chips.
What about options for turbo upgrades?
Thanks!

Doesn't anyone here modify these cars? Performance wise?
You're talking about an engine and car that are 17 years old and one that was forgotten while it was still new. The LT3 engine just wasn't all that popular, and an "econobox" car which cost 12-16k didn't have many fans. But it's not completely ignored. Problem is, there aren't many bolt on parts. I'd try the search button.
