  1. No problem putting a P79 on an N42 block, or an E88 on an F54. I believe that the Felpro head gaskets have all of the possible coolant holes, so there shouldn't be an issue with holes getting blocked off. It is always a good idea to confirm when doing assembly. The Felpro oil pan and cam cover gaskets are the best IMO.
  2. When I orginally got my 240Z, it had the Crown kit on it. Modified in a similar way with ethanol injection. It's a Rajay turbo, which you can probably still get parts for. I could not get more than 5PSI boost without serious detonation on my setup. It was the original L24 with an E88 head and flat tops. If you have flat top pistons, a good swap would be a P90 head, which will lower the CR, and be less prone to detonation. Some sort of intercooling would also help. I had two float bowls on the single SU to get more fuel capacity near the carburetor. The needle was what ever came with the kit. I've attached pages from the Crown installation manual. The last photo is of my Z. I long ago replaced this setup with an L28ET, and I have never looked back. I'm now working on a new L28ET engine for the same car. Pete
  3. Bumping this. I am starting to think about this again. From what I read there is no issues having the throttlebody upstream of the IC, as long as the IC plumbing is short. I am thinking that I would weld partitions between the runners where the IC meets the intake manifold. I'm thinking that this would simulate longer runners. Ideas, thoughts?
  4. Looks like a turbo block that someone put an N42 head on. Should be a decent setup for NA. CR should be around 8.5:1
  5. If they are junk, and fail, you will end up with an expensive boat anchor, that is why . The only reason to run non stock rods is if you are running the engine at high RPMs for long periods of time (over 7k). The Nissan OEM ones are good most most all applications except extreme road race or turbo applications. The best rods are Carrillo, but for $300 each, they should be. This is what we run in in the L28 road race engine.
  6. Will be painting the CF hood. It's a beautiful piece, but it just doesn't go with the theme.
  7. They are Rota RB 17x9.5 rear, and 17x8.5 front.. I don't remember the offset. I am running 2.75 ARP studs all around with 1.5" spacers in the rear, and .75" in the front. I'll take some pics tonight.
  8. Yes, I got the car back on the ground. Gas tank, differential are in. Brakes are operational. I'm moving in 6 weeks, and my goal was to have the car as a roller by then. So far going to plan. I'd like to get the windshield, dash, and doors on before I move. I'll post more pics shortly.
  9. IF they put an internally oiled cam in, and just put bolts in the spray bar mounting holes, the oil feed holes will still be open. You need to either swap the cam towers from an L28, or make some block off plates for the oil holes. Motorsport has them too. NJ has a pretty active club, with lots of knowledgeable Z owners: http://www.njzclub.com/
  10. Did you replace the throwout bearing and collar? There are a few different collars out there, and if you put a new one in there without the proper offset, you will have the problem you describe. Been there, done that....
  11. Pulled like crazy from 4000 to 7200
  12. Here is a race motor I built a few years ago. Unfortunately it had a crack somewhere in the block that when the coolant temperature exceeded around 180F, caused the radiator to overflow, eventually pumping all of the coolant out of the system. Here are the specs: - F54 block 1mm overbore - Bob Sharp prepped E31 head, shaved, 37cc chambers, too many mods to list - Custom Isky cam - Cosworth pistons, 12cc dome - Carrillo 133mm rods - 13.5:1 CR - Fully balanced - Mikuni 44mm phh taper bored to 50mm Dyno was a Superflow engine dyno. http://i160.photobucket.com/albums/t177/psanders240/clubcar/th_VIDEO0004.mp4
  13. As usual Derek, amazing work, and the attention to detail is quite impressive.
