  1. Don Potter Racing Cam?

    Here is my 3.0 liter dyno with Isky 490 cam and SU carbs. I have a later dyno that I can’t locate where I had the timing and carbs tuned much better. It looks pretty much the same but peaked 13hp more. And for Sh!ts and giggles my new LS1/T56 combo on the same dyno.
  2. Too many choices, HELP RB VS L28

    Getting that much RWHP out of 3.2 NA liters is going to be tough. It will be a high strung high compression engine that will probably require race gas. Going the turbo route makes things a lot easier but that is still asking a lot from 2.6 (guessing here as you didn’t state which RB) liters but completely doable and driveable but the RB’s I’ve seen making that much power have significant turbo lag. I also hate turbo lag but love the power. I use to poopoo the idea of putting a V8 in the Z chassis but after seeing a few beautiful LS1 swaps and riding in one I decided to go that route and have no regrets. It is so well mannered that it could be daily driven and power is instant, no turbo lag at all. I have more torque at 2000 rpm than my 3.0 liter had at full song. It put down 397 RWHP. It’s addicting! Maybe the Datsunworks head and twin turbos could get you there but your going in uncharted territory. I’d do it if I had the cash!
  3. Depends on how much you want to deal with the wiring. I got a wiring harness from http://www.wiringspecialties.com/ls1wihaforda2.html and it was literally plug and play...started on the first try. It was really well made. The harness that came with my LS1 was hacked a few times and really brittle. I probably could have used it and even got a book to help figure out what I need and didn’t need but I figured by the time I replaced all the damaged connectors and wiring and added my time in I would be better off paying for the new harness.
  4. Oh, the exhaust manifold/Headers. Just looking at it sure looks like the stock one will be a problem. It dumps right where our steering shaft exits the firewall.
  5. I just looked up the crate LS3 and it listed the hp at 435 and tq at 425 so I’m not sure if your getting something different than that but all of the LS stock style and FAST intakes will fit except possibly the truck intake which a crate engine wouldn’t come with unless you specified it. You will need to change the oil pan as the one pictured is too far forward. Here is a picture of mine with the strut bars showing how low the engine sits in the chassis.
  6. I used Hoke Performance 240Z mounts for my late 260Z (280 chassis)with an LS1/T56 and it works fine. Hoke's new 280Z mounts offer more room for the exhaust system, I used Hawks (American Racing) headers and had to downsize the exhaust from the header 3" out to 2 1/2" then back to 3" to feed through the mounts. The 280 mounts should easily fit a full 3" system. It didn't seem to effect my power output though. The steering shaft is a tight fit through the headers too. As far as I can tell it doesn't rub. The other problem I had was the LS1 alternator is different than the LS2 I had to trim the back plastic cover on the alternator just a bit to clear the motor mounts.
  7. LS1 260Z Project

    Made to dyno tuning. Ended up with [email protected] and 352 lb [email protected]
  8. After losing a valve seat on my 3.0 liter L6 I decided to go with an LS1/T56 combo after seeing Austin Hoke's (Hoke Performance) beautiful LS2/T56 build and the mounts that he designed to do it. I really think he did a nice job designing these and the workmanship is top notch. There was a question about which mount to get with the low mount alternator and it turns out the standard mount works fine for the low mount F-body alternator. I had ordered the low mount bracket that he designed to install the LS2 out of the GTO and that mount screws into the alternator replacing the bracket on the back of the alternator. So if you are using the F-body LS1 get the standard mount.
  9. LS1 260Z Project

    Hawks/American Racing Headers 1 7/8” long tubes. 3” duals to Y to 3” single to Magnaflow straight thru MF Performance muffler.
  10. LS1 260Z Project

    Finally! First and second start. A few things left to iron out but it runs and drives.
  11. Nearing completion of my LS1/T56 swap and I'm having problems locating a 92mm 90 degree elbow to fit my FAST 92 throttle body. They all list 4 inch elbows but I measure 4 3/8" outside diameter. Any suggestions?
  12. Almost finished with my LS1/T56 swap and have a question about the final wiring hookups. I have a Sikky wiring harness that made it really simple to integrate everything but a I few questions. The harness has a "Charge Cable" that hooks up to the back of the alternator as well as the single "sense" wire that is plugged into the alternator. The Camaro battery cables have an extra wire that looks like it connects to the alternator also. Do I need to have a connection directly from the battery to the alternator like that?
  13. Cold Air Induction

    Thanks! That works!
  14. Spray bar MIA

    Adlusting my valves today I noticed the spray bar was missing the piece that oils #6 valves. There doesn't seem to be any damage but where could it have gone? Could it possibly fit down the rear oil return? Does anyone know where I can get a new one?
  15. L28 dual duty build

    Honestly you will have way more trouble dealing with tuning the triple Weber's than a big cam. I had Isky 490 lift 290 duration and it was totally fine for street use. I used a pair of bored out SU carbs and all my friends with triples said not to change to triples as mine ran so well and triples would just be a headache. I would highly recommend a well set up set of SU carbs for the street. As for the ignition I would go with one of these 123ignition datsun.

    Holly Red fuel pump and regulator. $65.+shipping
  17. Holley Red fuel pump

    Yes, to still available.
  18. I've been debating on weather to sell this or not because the cam will need to be re polished on the 3rd, 4th, 5th lobe but I've been assured that it can be done. The damage happened when my valve seat fail on #2 cylinder. The springs and retainers are in excellent shape. $100+shipping
  19. Billet aluminum oil spray bar for L6 with clean out on the ends. $120 + shipping
  20. Billet aluminum oil spray bar

    Sold
  21. Billet aluminum oil spray bar

    Should work with all heads but you got me with the "drilled cam towers himself". Do you mean he tapped the oil feeds? I could include my cam towers...I'm installing an LS1 so I won't need them.
  22. Holley Red fuel pump

    It's for a carb. 7 psi @ 97 gph.
  23. Billet aluminum oil spray bar

    Yes, it's from Larry. I made the original thread on this that is a sticky now in the L6 forum.. I don't have a picture of it installed but I could screw it on the head in my garage if you want. What would you like know that having it on the head would help?
  24. Strange dying issue....Take a shot..

    I had the same issue with my 3.0 liter but I had SU carbs. It would restart but it wasn't pretty. I went from dead head fuel system to return line then added heat shield with heat wrap and wrapped all the fuel lines. Every little thing helped but the return line was the biggest help.
