    Lauching the SC400, quickest way!!!

    Fear not BUDzsx- These SC's are built like tanks, a torque converter will put a little more stress on the drive train but on coming from the stock motor with 230hp you should have absolutely nothing to worry about. Trust me I have that and more in addition to a 125hp nos shot, and have been...

    nitrous on a 92 sc400?

    Man, I have had my nos for over a year, my heater core can now be turned on or off manually from inside the car and also I had wired it to where the heater core will power off when the ignition is shut off. I did that for safety precautions. Bottom line is NOS is safe...or else it wouldn't be...

    How much wheel horsepower to aim for?

    Really WDoherty? Wow, lesson learned, thanks, I should have known that..... :27: No FWHP, with all the front wheel drive cars out their you would think that term would be used.. hhhhmmmm... Back to subject 330whp out of an 4.0l IUZ.. without air forced induction or nos.. I still think that...

    How much wheel horsepower to aim for?

    Yes Aaron, I see you dumped the 240 off your screen name..? Pro sounds better anyway.... Ok 330rwhp from 8 tb intake and cams on a 4.0L? Maybe....I still would think that would be hard to achieve but I believe you.. That 8 throttle body intake is for track use only, from what I am...

    How much wheel horsepower to aim for?

    Pewee- I thought we were talking about whp or hp at the crank... I didn't even think the stock cams could flow at 260 rwhp. These Iuz.. engines are rated 250-260hp at stock new on the soarer or SC and all I am saying is with a complete performance exhaust, intake, and ECU and a good tune you...

    TH 400 Adapter

    Another alternative is a company called www.boostlogic.com. They have built sc automatic trannies to run 9's in the quarter for $1800. Wdoherty gave me this hookup. I am still working with them, looks promising... Again this also is out of State...Texas Also the build up of the stock tranny...

    TH 400 Adapter

    Cribby - I talked with John at your tranny shop and he can definetely build up our stock Lexus trannies..the only problem is that he is located in New Jersey and we are in California.. I had discussed shipping costs but after it was all figured out I thought it would be way too much money and...

    How much wheel horsepower to aim for?

    ParaDoX667 - I am not so sure you will be able to squeeze 330whp out of an 4.0 liter 1Uz.. stock engine. Getting just to 300whp is tall order on a stock motor. With a good ECU (stand alone), full Intake and full Exhaust and some fine tuning you may be able to reach 300whp. I have been trying...

    TH 400 Adapter

    That's the problem I was facing when looking into the Th400 tranny swap on my SC400 was the adaptor plate find...Impossible it doesn't exist in the States. The biggest adapter shops in the US couldn't come up with an adaptor to fit...I looked into a company called American Adaptors, nothing...

    Two Trannies in 4 months

    Sorry to hear that, as RDM..., and Cowboy Bebop said in prior posts at or around 400 to 450whp, you can give up the ghost, or blow second gear... I fear the same may happen shortly with my tranny.. The Th400 is an interesting choice... harder shifts...is there an adaptor even made yet for that...

    nitrous on a 92 sc400?

    Yeah, I am sure you can find a couple of car engine fires or gas tank blow ups too if you search hard enough. If you really want to play it safe with nos and you live in place that has hot summers then don't get a bottle heater at all. Without a heating Element a nos bottle should never ever...

    Supra TT Big Brake Upgrade for SC400

    I have been to the LEXUS and TOYOTA dealers and went thru all the studs for all cars and could not match up any longer ones. That includes the IS300, 80 seies landcruisers, supra, etc...all of them are the same length...Kragen Auto Parts in the US was the only store that had the longer studs...

    nitrous on a 92 sc400?

    QCA - You are absolutely correct... It is a non-flamable dry chemical.... The Ka boom is from overheating. I have had my bottle peged at 1500psi+ and it was fine... My regular pressure is 1200psi most of the time... I may never push it to 1500psi+ again unless racing a monster and I need the...

    nitrous on a 92 sc400?

    No way, nos bottles don't blow unless really stupid efforts are made to blow them up, like over heating, not watching the pressure gage. Can be just as unsafe as any other gas related part in your car it unattended too.... I talk to the nos pro's they tell me it is safer then gasoline and your...

    Need longer wheel studs?

    I just went to the Toyota dealer and went into their warehouse and tried to match longer studs to any of the Toyota cars, and neither LEXUS or TOYOTA makes longer studs in the US for the SC400's this info coming from both dealers.... I found Kragen Auto Parts is the only place I can find the...

    Need longer wheel studs?

    IS300 wheel studs are the same as the SC's no change in length, the BMW longer studs are like $40 each from the dealer I am not that rich.. People I need some help on this I am coming up dry at every corner...I even checked BMW junk yards, nothing.. APR studs are again hard to order on line and...

    The Egr Block Begins?

    I am glad to hear everyone is happy with their EGR block and have had no reported problems too speak of... I must say who would of thought to recycle already combusted exhaust back thru the engine to help with emmisions? I would have thought that there would be no O2 or any other reusable...

    The Egr Block Begins?

    I just want to be clear on this one thing before we end this discussion ... This question is directed for Zir, and jtjerry, who have both already blocked off their EGR's on your IUZ..'s for some time now.. Have you guys experienced any ill effects so to speak from blocking the ERG? Any...
