    Lapping Compound...which grit?

    I just talked to him today. The answer is "medium".

    Transmission shift forks rounded

    I agree. That's my assumption as well, but I don't know what new ones look like. It would be great to see a picture of some new shift fork shaft ends! I wonder what could be causing the catch...

    Transmission shift forks rounded

    For anyone disassembling the transmission like I have, the torx bolts are all size T40. Any opinions on the shift forks? Anyone else have pictures they could post up? Thanks

    Rod shortening as an alternative to a thicker headgasket

    Well I've just remembered to say: Thank you everyone for your input! I ran that 8 thou from rods + 1.6mm HG by my machinist and he said that's exactly what he would have recommended himself. That's a GOOD SIGN to me! :-)))

    Transmission shift forks rounded

    I have my transmission partly disassembled to have a look at what may be causing a "catch" when going from 2nd to 3rd gear. Sometimes, particularly when shifting fast and hard, the shifter will catch inbetween the 1st and 3rd positions. I've found that with the shift lever housing in a...

    Uh oh.... high idle. 3k RPM high!

    Rod shortening as an alternative to a thicker headgasket

    You mentioned Squish earlier... I'd be very interested in understanding how I can optimize for that at this point. Variables like cylinder head protrusion from the block, (FYI I'm using the stock GTE pistons) headgasket bore size, etc. As for rod resizing/shortening, there is zero extra cost to...

    Rod shortening as an alternative to a thicker headgasket

    My crank appears to be perfect. This engine has never seen rodknock, and all bearings were within spec when I took them out, with no spinning. I checked all the journals with a micrometer and they are all perfectly round and in spec. So I wasn't planning to do anything to the crank. When you...

    Rod shortening as an alternative to a thicker headgasket

    I believe the bearing thickness should not be affected by a rod resize. The diameter of the rebored/lined hole can be made to the exact size as it was before. I think that's the whole idea of a rod resize... to make the hole the right size and perfectly round again, after the rod bolt...

    Rod shortening as an alternative to a thicker headgasket

    First off, I'm in the middle of a rebuild from the bottom up. I just got my head and block back from the machine shop. They needed to take off 8 thou from the block (fire rings, corrosion) and 8 thou from the head (warpage) so I'm looking at a total of 16 thou (0.4064mm) to make up. I'm...

    Deciding on a particular compression ratio

    I'd like to add a different angle here, which also demonstrates why 10psi on the ct-26 is not the same as 10psi on a larger turbo. It is the mass of the air entering the engine that determines the amount of fuel that can be added, not the pressure of the air. The same volume of air at 50...

    Radiator flush at thispoint

    He's talking about the hose that comes out the top of the heater union (not pictured in his diagram). There is an arrow in that diagram labeled "To Heater". That's where the hose is. You want to disconnect it at the other end. Here's a diagram of the hose...

    They're both out there... http://www.artsautomotive.com/GenuineFluids.htm (halfway down the page). I actually found that page when I was researching Toyota FIPG.

    maftpro questions

    As far as I know, this is normal behaviour. When you release the throttle completely (IDL contact closed) and the engine is above idle speed, the ECU will cut all fuel (I do mean 100%) to the injectors until the IDL contact opens again or the engine revs come down to idle. Since your AFR...

    maftpro v4.8 issues

    I've never had the VF issues you're describing... maybe some other people can chime in on that. For 4.8 quick setup, browse around the fullthrottletech.com forums, specifically here: http://www.fullthrottletech.com/showthread.php?t=3116 As for getting a bin file, if you reset the Maftpro and...

    MAFT-Pro VE Table

    My adapter is DC-DC. It's a car-specific 90w unit made by HP. Input: 10-32v 11A Max Output: 18.5v 4.9A I use ALDL all the time and I noticed it would screw things up the most when I was doing things like doing a data upload to the maftpro, or when I was stopping and starting replays of my log...

    MAFT-Pro VE Table

    If you are tuning with a laptop in the car, and you have an AC adapter that plugs into the power outlet in the car, make sure you unplug this and run the laptop on battery only when you are tuning for idle! I've found that the intermittent power draws made on the system with the AC adapter...
