  1. Has anyone used one? I'm wanting to switch out all my smaller gauges (clock does not work) I've already got Depo water temp and oil pressure gauges, looking to use the 3rd spot for some kind of fuel gauge if possible... anyone done anything neat looking for their fuel gauge if they removed the stock one?
  2. Serious, I've got them just sitting here... Why not try it? Engines not going to be left stock, obviously. Have headers on it now, looking getting one of my P79 heads worked on to increase airflow.
  3. So I picked up a bunch (6) of 240sx throttle bodies for basically nothing and was playing with them when I realized I could chain them all together and use them as individual throttle bodies for an L28. Would need custom runners made with injection ports, but that's fairly easy to fab up... I could also maybe do 1 intake per 2 cylinders and use the 3x mikuni carb intake... That's all stuff we're going to play with... My question to you smart people is how is the air metered in an EFI ITB? I've looked at a bunch of pictures and install guides and have not seen any indication of intake O2 sensors and obviously you can't use a MAF.
  4. Thanks for the info, I was going to use the N42 intake manifold (pre egr) and find a 60mm throttle body to put on it, if I go with the P79 head I'll use my 6-1 or 6-2-1 headers (they're both round). As for the actual induction I was thinking running the stock airbox without the top half (the flat flute) with the filter held in place by a custom mounting bracket. I'd think the larger rectangular body into the hole design would put more pressure into the intake than a "ram air/cold air" tube would when moving, but I'm going to play with that I guess. We've taken L28s apart before, for valve and cylinder wall repairs; I'm not to worried about parts getting miss matched. Also I have so many gasket kits... really want to use them... lol I'm wanting to put a Megasquirt 2 in the NA at some point, have a wide band O2 sensor and some other misc parts sitting around that could be put to good use. Mainly I just wanted to get as much out of an NA engine as I could and since I had all these misc parts I know people have done some crazy combos and gotten interesting results. Needed to know if it was worth doing a high CR on an L28 (read a few forum posts on it, and agree retarding the timing to get high cr engines to not knock kinda defeats the overall goal.)
  5. The engines are all being torn apart, regardless of if we plan to mix and match them. 4 of them have been sitting for 5+ years and the one that was running is a franken engine already and we're wondering how well it was put together so we're taking it apart (it was originally going in a different Z than the one it came out of, I got a rust free one a while back and my current one is about 99% rust, so it was going to be pulled anyway.)
  6. I mentioned that I was open to the idea of getting flattop pistons, but later in the replies I also pointed out that I have located a L28 out of an '83 ZX that should have a F54 with flattop pistons as well.
  7. How would an increase from 8.8:1 to 10:1 not be worth it? I'm legit wondering, since you are one of the pros on here Tony. I have no problem getting a different cam if I need to or having one of my stock ones machined.
  8. Well the turbo cam is 270intake/260 exhaust, could it be used in the NA engine with N42 + flattops? I've tried to research how all the different measurements of a cam shaft play into dynamic compression ratio, but it's just not something I'm comfortable with yet. Also I just got informed I can grab an '83 280ZX's L28 for cheap, which should be a flattop F54 block.
  9. Complete engines that have been disassembled due to sitting for years, we're replacing gaskets, checking seals, etc. Just want to make the best engines out of all the parts (one of the engines is not going back together)
  10. Well I was looking for a bit more theory craft... Why would you suggest dished pistons instead of getting flat tops for the NA? I was aiming for higher compression, but I'd probably need a new cam right? Also if I could get an F54 block with flat pistons would it make more sense to use than the N42 with flat pistons, being I'd have to buy pistons for the N42?
  11. Sooo I've got 3 L28 engines now all out of cars and wanting to mix and match them to make the best 2 I can. I'm building one turbo engine and one na engine. Blocks: 2x N42 (dished pistons) 1x F54 (brand new dished pistons, recently rebuilt) Heads: 1x N42 1x N47 1x P79 Cams: 2x stock 1x Schneider 270-60F-14 1x Schneider 270-60F-14H (I think this one is for a hydraulic head.) Turbos: 1x Stock L28ET Turbo Any suggestions for pairing? Also I'm aware I probably should get some flat top pistons for the NA since all of these engines have dished ones.
  12. So I'm playing musical cams this week and pulled my stock cam out which had 0.16" lash caps with 0.04" sinks (so they're effectively 0.12") is that stock? I can't see anyone selling anything close to that thin. My other engine has 0.16" lash caps but they're not sunk. What is the stock lash cap thickness? Do they have a sink?
  13. Well the plan is to run it EFI for now, but switch it over to 4 barrel carb in the future.
  14. EFI and I forgot to mention we have rocker arms out of the engine one of the cams came out of, so we're switching to those since they are already worn in for that cam.
