1badtgp Posted September 12, 2003 Report Share Posted September 12, 2003 Here's the deal. I'm going to mod the hell outta my car, because it's rare and fun. But I need to have the car runnig while I build an engine. I have a 2.8 v-6 out of my old 89 SE that I turned into a parts car. The oil pump went and it spun a rod bearing, but othersie it's in good shape. Can I use this to build the engine for the TGP? I mean, is the block and heads the same? That's really all that will get re used. Thanks. Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted September 12, 2003 Report Share Posted September 12, 2003 i'm not 100% sure, but i'm guessing they are the same. sorry i can't give you a 100% sure answer tho....i think Shawn would know - this topic was discussed a little last week or the week before.... also, while we're on the topic of 2.8 vs. 3.1 --- i wondering the rod/stroke ratio on the 2.8 vs. the 3.1. would a turbo 2.8 rev higher/faster? or would the increased dispacement of a 3.1 outweigh any better rod/stroke ratio advantages the 2.8 may have? joshua Quote Link to comment Share on other sites More sharing options...
TurboZ24 Posted September 12, 2003 Report Share Posted September 12, 2003 The only difference between the 2.8 and 3.1 (as long as both are post 86') would be the crank and pistons. Otherwise, the blocks are the same. The injectors might be different, I'm not sure about that, though. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted September 12, 2003 Report Share Posted September 12, 2003 A turbo 2.8 would rev a little faster due to the shorter stroke, otherwise the 2.8 and 3.1 are the same 'cept for what Curtis said. Robby Quote Link to comment Share on other sites More sharing options...
The Burning Rom Posted September 12, 2003 Report Share Posted September 12, 2003 Look for the topic from a few weeks ago about a TGP block. It'll tell you the differences between a normal 3.1 and a turbo 3.1. The NA 3.1 and the 2.8 are pretty much the same, except for the shorter stroke length. But that thread will tell you most of the differences. Of course if you're not going to run the turbo on the temp. engine, then it's not that big of a deal.
