  1. Don't want the flakspeed kit as its too much wonga!!!!!!!!!

    Are there any uprated conrods available for the 1GFE to work with the original pistons??

    Want to turbo my engine up to about 250brake and we all know the the std conrods give up their ghost at anything over 220/230brake. Also I dont wish to go over 250 brake as I will have to uprate the fuel delivery too - maybe in the future when I get bored with the power.

    What about the 1G-GTE conrods - where can they be got from?? Part numbers

  2. I think turbo's the way forward. I have done a lot of research on this and feel that this is best forward for very high 200's / low 300's. I know about the choclate con rods. Pistons are ok for mid 200's. I will be going with a rebuilt 1GTE bottomend with a mildly flowed head, a Garrett GT28BB turbo on a cast manifold when I can get my hands on 1 and a 3" turbo back exhaust system with a sports cat. Management will be std ECU with a Greddy Emanage - works well on the Supra's, so why not with the IS200's. Idea is to get it mapped in stages upping the boost a little every time so that the final map will be clean and smooth.

    thanks lexuxIT and Yeldarb

  3. Helix uprated Clutch, 1G-GTE bottom end, Mildly ported head, Uprated injectors, Custom ex-manifold, Garrett GT28 ballbearing turbo, 2.75" turbo back system with sports cat, Good front mount intercooler, Grooved discs with uprated should be good enough for mid 300 brake with braided lines.

    Have to look into injectors for sensible priced ones or can go for extra injector with its own control unit.

    Decent ECU or is Greddy E-manage up to the job??

  4. As said, both blocks are the same, but heads are different.

    The 1G-FE is 24V but narrow angle head, better for economy and lower down torque. On the IS200 addition of VVTI has added some higher RPM torque.

    The 1G-GTTE is also 24V but a wide angle head, better for power and higher RPM torque (long with twin turbos). At least thats what Mr T says.

    So you should be able to use the 1G-GTTE engine, but dissable the VVTI in the ECU. Your standalone ECU or Piggyback ECU should thake care of disableing the VVTI and sort out your fueling and ignition - providing you can get the manifolds for the engine. But you will have to use the crank sensor from the 1GFE and block off the distributor hole on the 1G-GTTE head.

    I would say std gearbox is ok if not for all out racing.

  5. My IS200 sport does not give me much more than 25 - 27 MPG. Plugged in a OBDII scanner and other than the P1349 code, there was nothin else. That code was erased and a rescan was done - all clear. Is there anything else to check/adjust as the car should do just over 30 MPG??

  6. Now I'm really confused.

    I always thought that the IS200 is an OBD II type car.

    I recieved the OBD II reader today and went to check for codes. Looked in the usual places for the diag plug but could not find it. So Looked in the engine bay and found the old type plug that Toyota uses, where you have to bridge 2 points to read the code off the flashinf ECU light.

    Enlighten me, what do I do?
