I have been running *very* lean in the 3-4k range under part throttle, the dangerous spot that we are told shows itself when you remove your EGR system and run a USDM ECU. Vf always seem to be normal when the off-the-chart lean condition shows itself. To fix this, or so I hoped, I purchased a...

Hey Guys, I'd like to ask if you could listen to my video recording of my 7M-GTE's new head noise and see if we can come to a consensus on what it might be. I need to flat-bed it a few hundred miles soon and I'm trying to get as much of the diagnosing out of the way before I put it up for...

Hi All, Over the summer I had a valve seat fall out into cyl 2 and trash the piston, fortunately it was only at start-up and the pieces did not go far. The walls are pretty clean, and while I can barely catch a nail on the wall of a scar I believe I should be able to hone some of it out. I...

What is the TCCS doing ~3500 RPM that causes a huge lean spike that is extremely hard to tune around? I initially approached the lean area with VE tables, and later with adjusting the Low/Mid User Tunes, Have tried different fuel pressures. I can effectively tune every other RPM/Load range but...

Over the last few weeks after work I’ve been installing the standard upgrades into my 1990 Supra GTE. I’ve installed a Walbro fuel pump, Aeromotive AFPR, RC 660cc injectors and a new turbo. I’ll be running Speed Density with a GM 3Bar MAP and IAT sensor. I’ve wired in a MAFTPRO running version...

I placed an order on June 6th with Supra Sport and have not had any communication to date with the company after the order. I have called several times and emailed them as asked on their website. I have had no response at all from the group. Is anyone in the know about the status of these...

Can we get a showing of Vermont/New Hampshire Supras by posting on the forum? Since there are no posts I have found yet and have not met any supra owners in the Burlington VT area yet I'd love to see if any are out there. I frequent the Lakes Region in NH and live in Chittenden County...

Problem Cannot build any boost at all. Car can be driven only if very careful not getting into the turbo. Has a hard time even getting up to 30mph because it will throw codes described below. Specifically 34 which we all associate with Fuel Cut as a result of High-Boost levels. Car runs...

Hello Everyone, I’ve gone through the forums and tried all the major first steps for diagnosing this problem, and am looking for your help to further narrow it down. Symptoms: Smokes at Idle (blue), but does not appear to while driving UPDATE: Now smoking on deceleration, seems to smoke...

We got the car running and it would not boost at all. Code 34. Found a loose intercooler clamp and tightened it. The car seemed to run better but was still running to rich 10.0 at WOT. Pressure checked the system. Found some more leaks. The clamps we got with our intercooler kit where to...

So my 7M Supra build of the past two years is just about come to completion, and only a few small bugs remain to be worked out before it's ready to be broken in, and had some miles put on her. My current problem arises when building boost. The boost controller is turned way down, and I’m...

My engine is going together, and the head has been mounted and torqued. The Valves and guides have not bee changed on this head, it was checked by a machine shop and certified as straight and good. I bought a set of used cams from a 7MGTE that were in better shape than the ones I had...

We are building a 7MGTE and have an extra hex plug. We had a total of two, but are unsure if the second came as part of the other parts bought, or if it is missing from a location in the block. It is a HEX style plug, the only location we could find was in the back of the motor, where one of...

I am having a hard time determining if my 7M GTE Head is good…or not. I had it sent out to Pittsburgh Crank for a rebuild, they cleaned it up, decked it, and mailed it back saying it was ok. My other shop who did the engine work, says it does not look good. He says…“the cam journals are...
