Ive gots a '90 beretta INDY with the 3.1/5 speed. im looking into a 3.1 tgp top end and computer swap. anybody have an engine they are selling and computer PM me and or email me ASAP! ive been looking forever, cant find a thing!

It might be easier to find a complete car for parts.   I just bought a TGP with 81 k miles for a grand.  IT needs some work, but they pop up for sale every couple weeks.  If you don't mind cutting up a car, for the motor, then you should be able to find one within a couple months or so.  Where are you located???

yeah i agree, but every time i see one, its always on the east coast or mid west and i figured it would be easier to get an engine shipped here than to try to pick up a whole car. im in Ritzville, Wa, near Spokane.

may have what you are looking for, just totaled my 89 and had the motor rebuilt 2 years ago.  What are you looking to spend?  Top intake manifold is aluminum ceramic coated, lower intake manifold is aluminum ceramic coated, new stock cam, lifters, etc.  All was blueprinted when rebuilt in 04.  Turbo is aluminum ceramic coated compressor side, exhaust sided is ceramic coated in black.  No  turbo blanket needed with this coating.  Exhaust manifolds are also ceraminc coated in black.  Crossover is a Jeff M. fabricated ($400)with ceramic coating in black.  Leave me a message--Located in Omaha, NE. 

Ii will be parting out 2 1990 tgp grand prixs with in the next month . 1 car has 224.00 with about 60.000 on the turbo The other has 144.000 on it Both cars run ex. I am in butte mt Perty close to you
