  1. So are you planning on doing any of your engine work or just contracting that out? Displacement and rpms are king with NA, so most move on from the L24 unless restricted by rules of racing or something . Or your like me and you what to learn and practice on your 24 before you spend bigger money on a 28! I am currently building a L28 and have a stroker by Rebello in the works. Hopefully I make most of my mistakes on the 24 before I get to the 3.2

    Like I replied on your other post, CZCC is a good site for resto stuff also!
  3. Don’t over look that L24 for a fun ride. Glad to hear others are staying true to Nissan NA ! Though Hybridz is an excellent site, don’t overlook CZCC. come up with a proposal of your specific build and guys here will help tweak it. As far a relativity , my L24 stays keeps my car just ahead of my sons BRZ, so 50 more HP should be real fun.
  4. Then there’s the theory of relativity ! How much HP do you have now at the rear wheels ? Have you ridden in a 250 HP Datsun? How did you come up with your desired numbers ? Have you ridden in a 150 RWHP 240z with some good gearing ? Striving for goals that are just numbers with out relativity ? My car is dyno’d 155 at the rear wheels. Is it fast -not really - compared to today’s numbers. Quick and fun - yes by any standard.
  5. I think you measured right for coil overs . They buy you a lot more room inside . I run 17x8.5 +4 and wish it was +10. That would have allowed 245’s on the rear with stock springs. +4 was really close on the front perch, so I actually flattened that side of perch slightly. Coil overs would have been no problem. I am currently running 225/45/17

    SCCA ITS built L engines?

    Good thing TonyD doesn’t get on here much anymore or you would get schooled on this. I believe I’ve read 208 hp on an ITS motor in its day, but I could be wrong . Voodoo and secrets that builders won’t ever give away. I believe in the rules there’s allowances for removing metal in certain places - head ! CR would be for race guess I’m guessing . Hell- maybe I’m talking out my ass
  7. I’d do it! Just put them back in same order and plastigage . Of course clean and inspect them. If everything spins freely your good

    L24 build, I need help!

    car-part.com used car part market . I saw a bunch in your area all day for 150$ Lots of them around . Cheaper and the Z guys don’t think about them You can’t open the ports as much as the earlier heads, but your just filling L24 bores so ...

    I’d say shoot for the most you can without forged slugs . The most CR with pump gas and the most cam that’s makes sense with cast pistons . Im anxious to do these pistons I have , but alas the next engine will be the L28. Time to move on from the 24, but I do love this motor. I’ve beat on it A LOT,and she keeps giving !

    Welding chambers is for seasoned veterans I think, but doable. You could shop for a maxima cylinder head which already has small heart shaped chambers . They would also be cheaper to obtain. I’d do a budget build first to experienced on these motors . Your not going to get a lot of knowledgeable help easily . Do a regrind for your cam. Cheap and reliable. I’d do a drilled cam and ditch the spray bar . Bottom ends are about bullet proof, so don’t spend a lot of money there.

    Search is your friend. I have a set of 86mm pistons on L24 rods available if you really want to punch it out. You have a sonic tester available ? Go big or go home on the cam . Later versions of the E88 aren’t the best combustion chamber , but maybe learn to weld close those chambers ? Running 490/290 and still very street friendly. Youll be limited on rpms with cast pistons , but still get 7k plus. Bump compression for sure. My e88 is shaved .050 to get some more compression . Lots of of ways to get power, but spend the time and money on that head, or find a different head with a better combustion chamber

    L24 block question

    Stock HG should be fine

    L24 block question

    So you should be able to shave the block quite a bit. Just make sure you bolt the timing cover to the block so you shave both.

    L24 block question

    Measure deck height on your pistons . I believe the L24 engine the deck height is closer to zero. You have more room to shave then in a L28 block. This is based on what I found on my engine when I rebuilt it. Now these weren’t stick pistons , but pin height should have been the same. How much is shaved off the head? My engine is a 71 with e-88 Head . Block is shaved close to .010 and piston was only out .005 ,and head is shaved .050 with bigger valves . No metal contact yet with a 490/290 cam

    .480"/280 cam and EFI intakes

    Not with the EFI- I was at 150 RWHP with the Mikunis and th butt dyno feels about the same
