    Paul Newman Championship Racecar on Sale!

    Hmmm, make an offer.... And it's not even complete, where did the passenger seat and the radiator fan go?? (/s duh) I bet Jay Leno gets it.

    T3/T4 Turbo that spools like stock?

    300hp is easy with the internal wastegated turbo, 15psi and the MSA downpipe. I'm running a very similar setup, low tech, dynoed 313 to the wheels with stock motor and 12:1 AFR.

    Ford Super 8.8 irs swap thread. Rear brakes too

    What a cute kid. My son had a similar condition, had surgery at 4 months. He's 17 years old now, doing well.
  4. Thanks for that link, very informative and encouraging. The silvermine kit looks great, but it requires 16" wheels, and I already have all the parts but rotors and pads for the rear. I've got about $200 spent on this so far so I will definitely try it before changing parts again. Interesting about the Porterfield equipped shoes, I would not have thought that would be supported. I've already been driving for years with the 280ZX front calipers and vented rotors, so I'll probably have to mess with proportioning in any case, and I really don't like drums. Ah well. I do appreciate the input. If I ever get this thing back on the track, I will give some more feedback, and eat as much crow as necessary.

    280Z Restomod Progress

    Proper fuse selection is based on the current rating of the wire in the circuits, so the wire can be protected in case of a short to ground. You are certainly picking your fuse correctly by finding the lowest rated part that won't blow in your circuit, but keep in mind fuses wear out with use, either through surges when the power is applied or through temperature rise by using the accessories in the circuits. Just to make sure you don't oversize your fuse, here is a guide for maximum fuse size by wire gauge: AWG 12 - fuse up to 20A AWG 10 - fuse up to 30A AWG 8 - fuse up to 50A http://bdfuses.com/fusesnwires.php

    Wow, that looks stout.
  7. As I said above, I have not had to modify the trans mount, just slot the T5 mounting ears, and it bolts in. There are several trans cross members out there that bolt in, at least on a 280Z, of course the 240Z is probably different. You can run a shortened version of the 280ZXT driveshaft, I've got a 280ZXT rear diff as well, but the input flanges on the R200 can be swapped out if you want to run a 3.54 from a 280Z.
  8. Yes, 3.54 R200. The 280ZXT T5 is more difficult to install than the Nissan unit, and I know lots of people have had great success with the Nissan unit, but I didn't have one. I like the way the T5 shifts, especially with the Mustang aftermarket short shifter with the hard stops, and I know it handles 400ft-lbs and 11 second 1/4 mile times reliably.
  9. For my 280Z, with L28ET and T5, I managed to find a transmission crossmember that almost lined up with the T5 transmission mount. I don't remember which Z or ZX it came from. I still had to slot the ears of the T5 to get it to fit. I don't know about a factory driveshaft, I had a custom one made for about $250.

    T3/T4 Turbo that spools like stock?

    I ran a 3.90 in my 280Z, and first gear was essentially useless, so I went back to the 3.54. I cannot attest to the "spooling", but I believe the reason I was able to get a faster ET with the 3.54 is I had one less shift to get to the end of the 1/4 mile. My best was a 12.89 at 110mph, 5600' elevation.

    T3/T4 Turbo that spools like stock?

    I've been running a T3/T4 with V1/V2 trim for years. Stock turbine, upgraded compressor, bought it from either Motorsport or Jim Cook, and I dynoed 313hp to the wheels at 16 psi.
  12. Yes. Make sure your thermostat is working, your radiator is in good condition and your radiator and reservoir are full. It's easier to keep the engine cool at speed due to the air flowing through the radiator. If you have a coolant flow issue, it will tend to overheat when your engine is working, at speed.
  13. Lowering RPM or changing coolant will not fix an overheating issue. If you are overheating at speed, you may have a closed thermostat or plugged radiator.
