gema Posted December 7, 2003 Share #1 Posted December 7, 2003 Hello all!I'm considering rebuilding and refinishing my L24 engine. I want to add Fuel Injection and convert it to a 5spd, and leave plenty of room for horsepower expansion. Race pistons and whatnot. I'm just curious as to your suggestions on what to do. I considered doing an RB swap, but I'd rather keep it stock but souped up. Thanks in advance.

Ed Posted December 7, 2003 Share #2 Posted December 7, 2003 If you are going to keep the L24 block and are going to replace the pistons. You should consider boring out the block as much as you can.

JEFF Posted December 8, 2003 Share #3 Posted December 8, 2003 gema - When I put the '78 FI on my 240 block I punched it .030 over and put in TRW flat top pistons ( true flat tops ). Compression went from 140 psi To 185 psi. The throttle response is awsome!- Jeffhere is the link I was trying to give you earlier:http://www.hammondsplains.com/zclub/techtips/index.html Link to comment https://www.classiczcars.com/topic/9213-engine-rebuild-questions/#findComment-59816 Share on other sites More sharing options...
280zx Fever Posted December 8, 2003 Share #4 Posted December 8, 2003 F54 Short Block P90 Head L20E Pistons = Nice combination But if i was you id shave the head heaps port and polish, race cam, flat tops, oversize valves.. and the list goes on If your going to do something do it right the first time Link to comment https://www.classiczcars.com/topic/9213-engine-rebuild-questions/#findComment-59851 Share on other sites More sharing options...

gema Posted December 8, 2003 Author Share #6 Posted December 8, 2003 Okay...thanks for the responses thus far. I want to keep the rebuild lower-budget, so no adding a block. I'd add the new head for FI, and rebuild/strengthen the existing block. I want to keep it as close to stock as possible, but simply make it better. Maybe turbo in the future, who knows. And sadly, I don't know chassis/engine codes that far back...P90 and F54 mean nothing to me, so please offer an explanation when you use carspeak (I'm learning, though!). Thanks again guys, and keep em coming. Oh, and by the way...anyone know much about the Nismo line for the 240z?

gema Posted December 9, 2003 Author Share #7 Posted December 9, 2003 Aaaand being the noob I am, I went and googled the sweet bejesus out of last night. If I go with the N47 head, I will go N/A. If I go P90, I'll turbocharge it. Either way...can someone draft up a parts list? Gotta call my local junkyard, and I need details for them. I'd hate to not get a piece I need and then be screwed when it's gone later. Quicker is better, as I'd like to have the FI done asap. Thanks!

Ed Posted December 9, 2003 Share #9 Posted December 9, 2003 First you need to make up your mind on what your gonna do. FI, TURBO or N/A?? This way we could point you in the right direction as to what will work and what you need to get. So far the only thing we know is that you are going to stick with the L24 block.Let us know.

gema Posted December 10, 2003 Author Share #10 Posted December 10, 2003 Okay, fuel injection is a must. And turbo is so....turbocharged and awesome. So a fuel injected, turbocharged engine, sticking with the L24 block to keep things at least half original. Thanks for the help thus far!

Ed Posted December 10, 2003 Share #11 Posted December 10, 2003 A turbo charged L24. I'm sure someone here will point you in the right direction. But I'm thinking that with all the parts you will need to do this metamorphasis you might end up using the entire turbo engine. Good luck.

JEFF Posted December 10, 2003 Share #12 Posted December 10, 2003 Take the original engine out ---- stick it in the shed --- Install a turbocharged L28 from a salvage yard, it's a lot less headacheto rework one out of the car then do the switch.
