  1. Looks like tripple mikuni's, 6-2-1 headers, and mallory plug wires. It says built internals do you know the specs? If its the 10:1 that most people do should be good for a high 14's car. Yeah the bumper/rear valance is too square for my taste. Good luck with your build and make sure you know what engine you want before you start. Many a time including myself do hybridz members change what engine we are going to put into our cars mid project costing us some extra money. The most popular swaps in our z's, in no particular order are... l28et (280zx turbo), sr20det (silvia), rb25-26det (skyline), 2jzgte-7mgte (mk4-mk3 supra), 302-351 (Ford motors), ls1-lt1-350-383-454 (Chevy/Gm motors)

  2. Sounds like somebody is having almost as much fun as me. I think its either a broken camshaft or something with the cam gears or timing chain. Open up the oil cap and check to see if both cams are rotating if they are then its must likely the cam gears are wrong. Good luck

  3. That would not be a legal SP car. You must run a glass windshield (and all other stock glass), full interior, and stock metal body panels.

     

    Well knowing my memory he probably wasn't in csp. Not sure what group he was running then maybe CM. Thanks and back to you local hybridZ forum.

  4. "Typical" SP legal weight reduction is around 15% of the original vehcile weight. I'll be corner weighing the car on Wednesday 7/12.

     

    Wow never heard about that. I knew someone running in csp at the national level (I think) running a really stripped early miata. It was fully stripped and didn't even have a front windshield. I remember him telling me it weighed 1800lbs and the stock weight was 2250 on those. He might not have been running at the national level though so is this a local rule kindof enforced are is it in the rule book that is too long to read at the moment? Thanks and good luck.

  5. I always wondered what those things could weight if fully stripped. If it could get below 2900lbs that would be nice. Aren't they 3300lb stock? Even when the car has stock suspension are you going to run in BSP? And then see how the suspension does. Or are you going to run in BS then upgrade to bsp when you have to you?

     

    I just read that the stock Z base model weights 3188lb. And some people have removed 300lbs. So looks like 2900lb should be doable. Maybe even 2800lb if you go more drastic.

  6. So you've lost 20lbs by punching holes in all those panels? So if 100lbs of weight savings equals about 10HP' date=' you've gained 2 HP by doing this? Seems like a lot of work for not much of a reward?

    I agree 20lbs isn't that much of a difference in any way breaking, acceleration, and turning. But if you remove 20lbs from that then remove the interior panels 10lbs. Sound deadening 15lbs, and etc... It can easily add up to 100lbs or more which is a big difference in not only acceleration, but also but in how the car drives. I would rather drive a 500hp 2000lbs car than a 1000hp 4000lb car. Sure theoritically(sp) they would accelerate the same but what one would be more fun to drive? The lighter one. I know I know not comparing apples to apples but you get why I love to make my z's lightweight. Then I add the extra power anyway and its all gravy.

  7. engine is from a MR2 with a distributor ignition supercharged 4agze

    going into Jover's 1985 ae86 corolla' date=' from Driftstar.com

     

    him and I are building the car.[/quote']

     

    One thing you need to remember when swapping from the 4age to the 4agze is the alternator on the 4agze is externally regulated while the 4age is internal. The external regulator is located on the passenger side of the rear trunk. Good luck I had fun with that swap:lol:

  8. Drilling a vent hole in the mbc will not fix a overboost/boost creep problem. It will fix a boost spike or boost drop but not boost creep. Your boost creep is the same problem 73turbo240z and I had. The wastegate isn't flowing enough air to lower the boost. Remember this turbo was used on a 5.9l I6 running at 18psi stock. I ported the wastegate just about to the max. I don't know if you can port it more. Your only two choices is try to port it more or go external. Its weird that it was ok on my car and its creeping on yours. The either means your engine is flowing less air than mine, your exhaust is more free flowing, or your engine is burning more exhaust from a more efficient burn than mine. What exhaust are you running right now?
