You are running a bit rich there. Are there ANY modifications to the engine or have you put it completely back to stock? Check for codes.

Are you positive that it has a Lexus AFM? The stock AFM housing and the Lexus AFM housings both look almost identical. One way you can tell is that the round outlet of the AFM is larger on the Lexus unit when compared to stock.

What color are the plastic tops of the injectors?

This isn't the first case of ARP flywheel bolts backing out that I have seen on this forum...not to say the OP isn't at fault but I've never heard of stock bolts backing out while its becoming quite common to see ARP bolts back out.

Just peel or scrape off the green insulation and you can solder strait to them. I have done it without any issues for the same reason.

Looks amazing!

Ah thanks, I just re read your first post and I had read it backwards for some reason, that makes sense.

Intuitively I would think the battery/chassis ground would be more noisy than the E2 sensor ground, is this incorrect? Do you think it is important to keep them separate or would it make a negligible difference?

K thanks JJ. Any idea why the AFM is chassis grounded? Either there's a lot more going on in there than the schematic illustrates or I just don't understand how it works. It looks as if vref comes in, goes through a diode, then goes strait to ground, without anything else using the vref.

I know this is an old thread, but is it alright for both the karman vortex unit and the air temp sensor to be grounded to the ECU sensor ground (pin E2)? I suppose it wouldn't be a problem but then again, Toyota ran two different grounds, probably for a particular reason that I can't think of.

Are you talking about the widemouth one? I have one and it is pretty decent. It is not perfect. I found it was a tad bit longer than the stock downpipe, but everything still fit. Also the flex section is touching the engine block in one place, but not a big deal. Other than that it fits and...

Awesome thanks for the input. I may have an extra regular wire injector clip sitting around, if so I will use that for the number 1 injector. If not I will either do what you did or rotate the injectors so the clips are underneath like someone else suggested in that thread. The RC's came with...

Just bought a set of RC injectors that came with the push release style injector clips (rather than the snap in wire version) and it looks like it is going to be a tight fit on the 7m. I am just wondering if anyone has used this style of clip and does it fit between the rail and the head/valve...

The additives and viscosity will vary from ATF to power steering and also from one brand to the next, but destruction of a system (ours) from using one vs the other is unlikely, the are both designed for use as hydraulic fluid. Using ATF or engine oil in your brakes is certainly destructive. On...

What exactly do you mean by ATF does not have oil? ATF is petroleum based. Also, the seals in a brake system are specifically engineered to be used with brake fluid, using anything besides a DOT approved brake fluid is a bad idea. If my system was ever contaminated with a petroleum fluid I...

They are both hydraulic fluids, so running either one shouldn't be a big deal, in fact you could probably get away with running many different kinds of oils. One issue is that there may be certain requirements for different materials used in the system, such as rubber hoses or seals. Honestly...

Out of curiosity, where did you send your parts for zinc plating? Been wanting to get some misc brackets and things zinc plated but wasn't sure where to send them. And FYI some 7m's came with a heater pipe that has no RHD fitting on it. I think it might be the 89+ versions. I have one on my...

I have used the Taiho bearings from napa a couple times, they are fine. Taiho is the same company that supplies Toyota as far as bearings go (their symbol is stamped right onto the factory bearings). They will need to be clearanced.

1. Take some pics of the head and post them. I think you are referring to pitting around the water jacket openings. This won't be a problem as long as they are not large enough to compromise the seal. 2. No, nothing special needs to be done. If the flywheel has a step (don't remember if the 7m...

Nice work. I was under the impression that the biggest restriction was the pulsation dampener itself. I took a look at it and its a strange connection, doesn't work like a standard banjo fitting/bolt. There are four openings on the underside of the sealing surface of the dampener, and fuel flows...
