Guest Tom Scala Posted June 11, 2002 Share Posted June 11, 2002 I turboed the stock 70K mile block in my 78. I've got over 10,000 miles since, running up to 17 psi without a problem yet. I could be on borrowed time but it has lasted longer that I thought it would and is no worse for wear. I did bolt a P90A head on top to lower compression and a turbo oil pump though. There really aren't that many differences between the turbo & n/a shortblock. Rods,bearings & crank are virtually the same. Mainly the pistons & rings are different. They are still cast on a turbo but have the rings a little furher down on the skirt probably to keep them away from the extra heat & pressure of the boosted chamber.

Lockjaw Posted June 11, 2002 Share Posted June 11, 2002 The rings would be thicker also, on the earlier model 280z pistons if memory serves. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 19, 2002 Share Posted June 19, 2002 I have been wondering the same thing....I have a stock 77 280z 2+2 that is rust damaged to much to do the v8 conversion. I think givin it a turbo would be the best way to spice it up a bit. Gotta have fun before the thing falls apart from rust Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 20, 2002 Share Posted June 20, 2002 I know that some people recommend not turboing your car, since there is an engine that was engineered for a turbo, but I am planning on turboing a 280z this summer, with the N/A block, pistons and rings, but a 2mm headgasket P90A head, and ZXT fuel parts (to make sure I have the right A/F mixture) dist. and oil lines. Hope this helps in any way, shape, or form Mark Quote Link to comment Share on other sites More sharing options...
yo2001 Posted June 20, 2002 Share Posted June 20, 2002 Get you a set of good pistons with good ring land and should be good to turbo some. the F54 block would be prefer for the turbo because there are more support around the cylinder walls.

Tony240ZT Posted June 22, 2002 Share Posted June 22, 2002 My turboed L24 should be inspiring enough to have others turbo a non turbo block. It's a stock bottem end with around 100K miles with a P90 head. T3/T4 turbo, intercooled, `83 ZXT electronics, and I'm pretty sure I'm running high 13's right now. My CR is 7.54:1. The turbo pistons are better setup for the forced induction, but as long as you keep an eye on your air/fuel ratios and make sure not to ping (very much) then all should hold together for more than a few thousand miles.

Guest Tom Scala Posted June 22, 2002 Share Posted June 22, 2002 If you have a P90A don't use the 2mm Hg. It will lower compression too much. Quote Link to comment Share on other sites More sharing options...
