302,000 here, but three engines; One BHG, One bad head, (cylinder coolant rot), one rodknock. Now completing the build of engine #4.

Spray down the pistons/ walls with some sort of heavy lubricant that won't drain off. seal the fuel lines somehow- even if you just plastic wrap the ends.

Agreed. A bit shorter and it'll be great. Why do you put down the duct tape first, does that allow you to remove the flare? Does FG not stick to duct tape??

Do they have any part numbers on them at all? I'm sure someone on here has a set of stockers that they can check for you.

I agree.

I'm pretty sure the Lotus exige has a variant of the 2ZZ motor.

You can clean the ex. valves(it's just carbon buildup), but it takes alot of grinding. I got tired after only two valves, and got on Ebay and bought a new set for $60 shipped.

Werd. I have the crap Autometer mech. boost gauge, and it reads 2psi when off, meaning I've got 18in. vac when it shows 16, and 12psi boost when it shows 10.

will a wideband O2 sensor last a good long life like the stocker?

Yeah, my car surges a bit under moderate to hard acceleration when very cold. That being said, I no longer try to run it hard till I see the temp needle starting to rise off the peg. As for the AFR's; as mentioned above, the AFR should occilate slowly at idle, and rapidly through full range at...

I misread your original post. You shouldn't put post 88 injectors(high impedance) on a pre-88 car(low impedance), because the injectors will be slow to open/respond(though you can put low imp.'s into a later car). If you want 550's in your 90 car, best to go buy some.

Hella rich at idle through highway cruising could also be a defective CSI. But you should try testing for boost leaks as Grim says.

The plug and play injectors are Denso's, and possibly some HKS units. The Denso's have a pinkish red color to the top area.

Until you get a set of 550's, I'd say add 5 more psi to the AFPR.

Well, he said that the relay is clicking, so it doesn't sound like that's the problem.

no?

Yes, but only if you're using the NA tranny- A.K.A. W58. PS- If you're using an old OEM clutch, it will slip at anything above ~220RWHP.

Check the wires on the CPS, they sometimes get crossed or poor contacts. Try moving them around a bit. Also, If you did the valve cover gaskets, you messed with the coil/igniter connection. try wiggling that a bit.

The starting issue is the solenoid on the starter. You CAN replace the faulty contacts inside the solenoid, but it's easier to replace the entire starter, and only costs about $60-75 for one w/ warranty. The CPS has an o-ring around it's base. If you get one from the dealership, you can...

The front one has to be dimpled- aka pounded in the center, as it's made convex. That drives the outer edge into the block seat. I got a brass set on Ebay, packaged specifically for the 7M (all metric).
