This may sound like a stupid question but what the heck is monitoring the VF mean? I haven't gotten to trying anything yet as it has been raining and work, but I will as soon as I get a chance. I am currently running the vacuum source to the afpr through the VSV like it is factory. Is that a...

The reason I said 10.2 is normal is because it is abnormally normal for my motor since I put it back together. Its been running rich since I finished reassembling everything back in August. The ecu will not lean the air fuel ratio out any further then 10.2:1. I know the tps problem won't fix the...

Yes to the j-tube delete. What do you mean by my foot is on the gas or the a/c button is pushed during the test? Are you meaning when I am checking the check engine light, the a/c button is depressed or my foot is pushing on the throttle? Also a buddy of mine was mentioning that the afm...

I forgot to mention the bov vents to atmosphere and AEMs 320 lph in-tank fuel pump.

The injectors are brand new from Rockauto as of June or July. The mods to my motor are as follows: Brian Crower stage 2 cams with 264/264 degrees duration advertised and .336"/.336" lift compared to stock cams of 256/256 degrees duration advertised and .297"/.297" lift. Titanium springs and...

7M4EVR - Since you want to be a douche, these cams from Brian Crower are plug and play cams designed specifically for the 7M-GTE motor. According to BC, one can even run the STOCK springs with these cams. They are .008" longer advertised duration and .019" longer duration at .050." With that...

For an update and to see what you guys think... I tightened up all the t-bolt clamps this afternoon and dropped the fuel pressure and took the car out for a test drive. I drove roughly a mile with out really getting on the throttle with the afrs reading the normal 10.2. I came to a stop and then...

Thats the sad part about all this. I am only topping at 6 psi right now. Whats a good way to do a boost leak test?

So I am hoping someone can help me shed some light on this issue of mine. I recently got my 91 back on the road after an extensive rebuild to the front half of the car including the motor. I put BC stage 2 cams, a 57 trim ct26, Evo 8 560cc injectors, and a Lexus AFM housing for performance...

Correct me if my logic is wrong, but could the turbo cause an issue because it is drawing in more air. The computer uses coolant temp, air flow, rpm, timing, and throttle position as inputs for changing the amount of fuel being added in at any given RPM. Being that a larger turbo would draw in...

I got my 91 MKIII back on the road around four months ago after a ten month rebuild and I didn't notice any problems then. But as I drove the car, I noticed that when the car would roll backward either from being on a hill or putting the trans in reverse, it would take a lot of effort to get the...

7M - The boost gauge would be fluctuating as the pressure bleeds off. It hits 6 psi and holds it until the engine hits fuel cut. The other thing is, how can a boost leak only be dramatic in the higher gears? What is a good pick up point for a boost gauge just so I can make sure that at least is...

I realized shortly after I posted the first post that I forgot some information. I am running the fuel pressure at roughly 45 psi at idle. Not sure what it is when I'm doing a hard pull. I can't see the gauge. Secondly, I am only running 6 psi for breaking the engine in so I am almost certain...

Yes. Think about how you have changed the geometry of the steering. When you lowered the car you lowered where the rack and pinion is in relation to the ground but you have not changed where the tie rod ends are located on the steering knuckle. The angle of your tie rod ends will cause some...

Since a lot of people in here are or have run the 57 trim CT26 with upgraded afm and injectors, I am wondering if anyone has had the problem of hitting fuel cut? I have the same swap with Brian Crower stage 2 cams and I am still hitting fuel cut around 3100 rpms if I am in third through fifth...

I can speak from experience on this having just put my Supra back on the road after roughly a ten month build. I highly recommend upgrading anything inside the engine as I am sure you are wanting to do. Do lots of research on what other people are upgrading and to what brands. Also, figure out...

I ended up finding a thread from three years ago about someone else having the same problem I am. 1J highly recommended taking off the head and redoing the whole thing. Not looking forward to doing that since I literally put the last piece on before being able to fire up the motor two days ago...

Yeah the block and the timing cover were decked together. I finally uncovered the front of the motor enough to see that the leak is coming from the side above one of the bolt holes. It looks as though the gasket didn't stay in place when I put the cover on the motor. I forgot to mention in my...

I was trying to start my freshly rebuilt motor today and it sprung an oil leak. It is coming from the timing cover where it seals to the engine. What is the best way to replace that gasket? I am more concerned with causing problems with the head gasket if anyone can give me some advice on...

I am nearing the end of my rebuild and I was getting ready to install the stock accordion hose onto my lexus afm housing and discovered the hose will not fit over the housing. For those that have switched to the lexus afm housing, how did you fit it to the accordion hose?
