I see you are using Ross pistons. Was the stock 885 crown shape used?

Aside from weight, how are 24v rods "better"?...

The supply side is open all the way to the pump. The check valve is internal, but many people add them in-line.

Do you have a fuel pressure tester? If so, check pressure with car running,...

A stock m20b25 can easily make 400hp with a turbo. Just get the head to stay down with studs.

It's not the 8°, it's the ability for the ECU to "catch" what's going on. 8° can be the difference between going fast, and fighting detonation.To "jump" from map to map, you would...

This. Or the veins are worn if it is the fuel system.

A fuel pressure tester would make quick work of that diag.

A backyard way of kinda checking the pump and check valve is...

They aren't too short, note the spacing between the o-rings. They are just the newer style EV1.

The FPR is a simple device and easy to check. If there's fuel coming out of the vacuum line, it's done. If it hold vacuum, it's good.

That aside, you should be able to get in there, but honestly...

At WOT, the ECU is expecting the RPM's to go by very fast, so it disregards many sensors (basically open loop). I bet your AFR's were all screwy since the ECU can't keep up with the RPM changes.

Check the main relay socket. It's the three relays under the cover on the driver strut tower. If that relay loses power, the DME completely shuts off. We have to zip tie them in place in the endurance...

Not only heat expansion, but you ever try bolting a 90° gate in a rigid setup?

Everything looks great so far!

I like the tidbit about Vaseline. Typically when working on cars...

Well, after-all, he was already 28yr old in Clockwork - which was now 49yr ago......

Verify the ECU is seeing WOT maps. The difference between the higher part throttle cells (1x8 cells on the right side) and WOT (1x8 cells in it's own map) is ° of timing at MBT. If the throttle switch...

198 is a little optimistic, but not out of the realm of possibility. One of our clients is making 208/189 with our head, stock size ST valves, 288 cam, b25 crank and 12.5:1 pistons (lightened/balanced...

^^^I am going to make an educated guess with 184whp, 192wtq. :P

Ah, then there's probably a bent shift fork inside the back housing. I have a couple here in the back of the shop that are stuck in 3rd, just haven't taken the time to pull them apart.

[ForcedFirebird]

Get under there, remove the selector rod, and make sure it's the shifting mechanism, not the trans itself.

My daughter aka mini me is quite an artist. Pretty sure I will donate all my vintage circa 1998 studio equip in exchange for an upper sleeve that can be hidden behind a short sleeve biz environment....

Did you get the fuel situation sorted?...
