Russ15 Posted February 18, 2015 Share Posted February 18, 2015 Hey guys, craigslist has an engine up for sale for $200 that has a F54 block and a P79 head. I am wanting to go the turbo route and I know the flat top pistons aren't the best choice over the dished. My questions is, is it worth it to buy it and switch out the head to a P90 or pass on this one? Quote Link to comment Share on other sites More sharing options...
NewZed Posted February 18, 2015 Share Posted February 18, 2015 The P79 and P90 have the same combustion chamber volume. Swapping heads will only get rid of the exhaust port liners. Read more stuff, especially the FAQ's on the L6 engine. Quote Link to comment Share on other sites More sharing options...
Russ15 Posted February 18, 2015 Author Share Posted February 18, 2015 (edited) Sorry I meant along with switching out the pistons and etc.. I found some good links of the differences/similarities between the heads here. Think I'll hold off for a complete turbo engine (L28et) as this will be my first rebuild.

NewZed Posted February 18, 2015 Share Posted February 18, 2015 If you're "rebuilding" to specs. for a turbo engine and you're buying new pistons anyway then all you really need is a good block and head to start with. $200 for a basic 280ZX NNA engine isn't bad, if it's in decent shape. Beats the typical wrecking yard price. L28ET engines are hard to come by. Quote Link to comment Share on other sites More sharing options...
Russ15 Posted February 18, 2015 Author Share Posted February 18, 2015 I'll have to take a look at it in person to really see. The engine is being pulled from a parts car and the picture of the engine makes it hard to make out what the true condition is. He told me it was running recently but needs new injectors (would be switching those out anyway) and that the fuel pump works. Here's the picture that was sent to me.

NewZed Posted February 18, 2015 Share Posted February 18, 2015 You can't tell much from external appearance. I had a fine-looking engine (they all look the same really) that was high miles, worn valve guides and old seals, only ran well after I beat on it. If you can't drive it or hear it run, you're at the same level of knowledge as a wrecking yard engine, except that most wrecking yards have a replacement guarantee.

HowlerMonkey Posted March 2, 2015 Share Posted March 2, 2015 F54 with P79 in good shape is well worth 200 bucks. Mine puts 219hp to the wheels with 7 pounds of boost on a dyno dynamics chassis dyno with an untuned M30 ecu. Quote Link to comment Share on other sites More sharing options...
Tony D Posted March 2, 2015 Share Posted March 2, 2015 Any L28 takes a turbo slapped on it just fine. You don't need anything special. Quote Link to comment Share on other sites More sharing options...
