Has a Grimm Speed Turbo and pushes 20lbs boost. I'm deciding what to buy for more hp. Any Suggestions?

Not much. Just has the turbo and a deleted resinator. The car has 220,000 with no lights on the dash. There could be other mods because I'm the 4th owner. But I don't see anything other than the turbo being aftermarket.

If it really is just the turbo... anything you do to improve breathing is going to help... intake, exhaust, up/down pipes, etc. The turbo might be getting choked off a bit by the stock bits.

Look at upgrading the intercooler maybe..? Something larger to help cool the volume of air... possibly consider going front mount if you really want to open up the power?


Otherwise a good dyno tune is your best bet.
