  1. I was thinking a 12psi on a conservative tune with ign timing adv 2 degrees would be ok,

     

    You need to know total timing. 2*advance doesn't mean anything if you are running stand alone. I'd run more boost, 16-18psi. Try 22* total. I would'nt run less than 20* at full boost. You can run higher boost and be reliable as long as you aren't on the edge of deto or running too muach timing. I run alot of boost and have reliablity.

  2. http://www.microtechefi.com/ http://haltech.com/ You can use your stock sensors and coils with either. Go into downloads and it shows the wiring.http://www.microtechefi.com/html/WIRING.htm Haltech also makes this http://haltech.com/interceptor.htm. for the SR20. What ever you get you will need a wideband to tune it properly. I would get whatever turbo and injectors you will be using before tuning. A T25 won't move nearly as much air as a T3 or larger turbo at the same boost. So sense in tunning twice. I know Microtech will put a base map in it for your application to get you running. You can probably find someone with a similar setup and use there map and fine tune from there, with whatever system you end up with.
  3. hahaha... I like this guys opinion of this diff

     

    "Why pay $250 for a "Phony Grip"?

    ( or is that phantom-slip ? )

    When you can have a Helical !!

    Or worse yet' date='

    Pay anything for a chinese LSD !

    Oh we-Be junX

    They can't get their 1.6 Honda LSDs

    to stay in one piece,

    Just what is a 2.4L KA, or a 2L SR

    going to do to one of them !

    Do you want a JDM Spec car,

    Ha, ha. He's a "good o'l boy" from Texas. Seems he doesn't like people from

    Syria, Iran, N. Korea, or - france either.

     

    So does anyone know if these work in the long diffs? I don't see why they won't if it's for a 12mm ring gear.

  4. have you seen them perform? or been told about it?

     

    I played with it. I haven't personly seen one on a car though. I know the GT series turbine a/r's are typically larger compared to the T4 a/r's for the same application. If they will work for someones particular application though, they are a good deal. There are a few 7M MKIII guys running gt4082's and gt4088's. Don't remember the a/r's but they are on Supraforums.

  5.  

    Just be very aware that just because it has GARRETT on the casting' date=' by no means does it say for sure that its a genuine GARRETT turbine. The real mccoy Garrett GT40 sells in Oz for about AU$2000.00 so do your exchange conversions and see what it is in US$.

     

    Cheers,

    These are genuine Garrett turbos. I've seen them in person. They have the garrett sticker on the backplate with a part/serial number. They are standard bushing type bearing with 82mm compressor (gt4082).

  6. You don't need to pull your crank to have a flywheel balanced. It would be no different than putting a flywheel from another L on your car. They are balanced seperate from the engine. Just like your wheel and tire is balanced seperate from the hub. HKS sold flywheels that were balanced. They never required a crank sent in.

  7. Everyone drives their car "hard"' date=' by their interpritation. However, there are different degrees of HARD. Clifford's got a track car and I assume does track days, so I can draw some assumptions that his street car, making big HP and torque numbers, isn't just a trailer queen. However, not seeing chassis flex is just strange, based on my personal experience. Maybe he doesn't drive it often? I don't know.

    I drive the street Z every weekend and some weekdays after work. Have been doing scca solo with it too as it's alot cheaper than road racing. I can't remember ever driving it without doing a full boost (26 psi) pull in atleast one gear :D before shutting it off. It does have 275mm R coumpound tires too.

  8. The compressor wheel and turbine are balanced individually. Only Turbonetics that I know of balances as an assembly. When they do they take the weight off the nut. I have replaced turbine wheels on T netics turbos and used a new nut without problems. It's the one on my car now. I have never had a turbo leak or come apart that I have rebuilt or swapped part on and have never balanced any of them. Of the 2 local turbo shops I get parts from, neither have a balancing machine and will tell it's not necessary.

  9. I think it's because I have to look at my boss' 700hp procharged nova every day.

     

    Get a ride in that Nova and then it will be easier to toss the L. An LS1 is not any heavier than an L and will make power power than 95% of the turboed L28's out there (on pump) while being completely stock. Ad a turbo or SC if you need more. If you want a 12 sec car keep the L. If you want to run with fast cars and 1 liter bikes ditch the L.

  10. I would look for a cheap electric vac pump if you plan to do this often. You can find them on ebay. The cheap venturi ones work but take some time to pull it down. I don't know about 280's but 240's have marginal a/c when over 100* outside. I would also stick with R12. R134 was gone up in price, atleast here. My system only used 2 cans. It cost me less than $20 to use R12 over R134. Look on ebay for it. The more you buy the cheaper it is. Replace the dryer and all schrader valves too.
