    Thoughts on FFIM's and throttle response

    Oh, so it really does overfeed 3 & 4... I was being facetious.

    Thoughts on FFIM's and throttle response

    Cylinder three and four are the only two cylinders run off the throttle body, then. Cylinders one and two seem to be fed only from the IACV. ;)

    Thoughts on FFIM's and throttle response

    You can always just turn up the boost :) 2JZ Billet heads are already being tested. Nothing is impossible, but cash flow may involve selling a house. We are comparing oranges to apples all over the place.

    What did you do to your supra today? Pics

    http://www.myraceshop.com/Legacy_Power_Steering_Controlle.html I know it says Corvette wheel sensor, but from what I understand, the Toyota and GM sensors both output the same signal to be converted.

    What did you do to your supra today? Pics

    Removed the A/C condenser, then decided to just remove the mechanical power steering pump too... Lots of free room. I am installing a Toyota MRS electric power steering pump, and I found a nice place for it. Reusing all the Driftmotion stainless braided line kit for the standard JZ power...

    Thoughts on FFIM's and throttle response

    Close enough. Just gotta find another designer who made a better head than GM. Lots of them out there, and they may not have used a flow bench honestly.

    Right about RPMs. Keep the speed of the pistons lower, engine will live longer. The 7M has a beefy stroke as it is.

    Thoughts on FFIM's and throttle response

    Computer simulations may not exactly represent real situations. That is why you make a huge plenum/manifold so that air will always be distributed equally at a specific resonating frequency tuned towards the RPM band target (ideally), and it does with race manifolds. The amount of air flow...

    Fried 2 1jz's, Any Ideas?

    This is tough man. What oil filters are you using? Did you use new O-rings and gaskets when you put the pan, the pickup, and the pump onto the block? Basic questions, but I'd really like to find out what caused the problem.

    Thoughts on FFIM's and throttle response

    Air gets turbulent towards the speed of sound and how restrictive the pipes are. The math is on other forums. 700rwhp is fine with 2.5 inch pipes. Those shooting for more may want to go with a FFIM with a huge plenum/throttle body to accommodate larger piping for large/efficient turbos and...

    Sound performance ffim

    Part of the game. A lot of MKIV guys do the same with aftermarket intake manifolds like the Hypertune. I had to relocate the battery in my MK2. Wasn't a decision I regret at all. Just no way to fit such a huge manifold, unless you start moving other stuff around. Plenum volume, angle, and...

    Sound performance ffim

    Just call and ask. I am sure Larry and Elliot wouldn't mind making one.

    What did you do to your supra today? Pics

    Mounted the Nitrous assembly, with mechanical and electrical sensors. Installed fuel rail end and TwinsTurbo throttle cable bracket. Waiting on more fittings and parts... Bit dirty, eh?

    How is everyones 1JZ holding up after +-25 years?

    They are great engines. Pistons are moving slower compared to the 2JZ counterparts, so theoretically a lot less strain accumulated over time and mileage over the 3.0L variant. I'm rebuilding with a couple of upgrades.

    Who wants a FFIM from SupraSport? Gauging Interest

    Ah, of course. Choices are good. :)

    Fried 2 1jz's, Any Ideas?

    That sucks. I still suspect the pickups on the pans are too close to the pan itself. This is a tough one...

    Fried 2 1jz's, Any Ideas?

    Did you reuse your lower oil pan? I've been using the ACT extreme clutch on my JZ motors for years, thousands of miles, countless pulls and startups. Others have too. You have an oiling issue, not a clutch issue. I've also been using 2JZ oil pumps for six or seven years, but oil pressure is...
