what fuel pump are you running? I highly recommend not using the C5 pressure regulator - it will dead-head the pump at higher output levels.

Aeromotive Stealth 340lph. What do you mean it will dead head?

Not planning on having more than 500hp to the wheel for now.

I've been pretty burnt out on taking pictures lately.

Latest progress:

Radiator/Fan assy and hoses installed. Had to tap a fitting for steam tubes. Sealed it with JB weld.


Drive shaft installed, U joints greased

Added Integra speedo, not perfectly centered but itll do.

Sway Bar relocated

Roughly aligned the front end

Sanded/primered fenders and installed.

Trans cooler and lines installed.

OPS had broken off prior to engine install. Since im not using it, i cleaned it with acetone and sealed it with JB weld.

Aftermarket FPS, OPS, and CTS installed.

N2O Solenoids wired and fully functional

Brake switch wired to relay and fully functional

Lots of other stuff too. Only a few things left to do to get this thing on the road. Need to figure out how im going to install my intake. Theres not a lot of room behind the radiator/fan shroud. Need to install the hood and modify the hood inner panel so it will shut. Need to shorten the trans dipstick. Need exhaust.

Drove it for the first time since the swap last Thursday. Due to open header, and the O2s being 2-3 inches from the atmosphere, the engine loads up in closed loop mode. But when I punch it, this thing rips.

Oh yeah, new water pump. Went to fill the cooling system, and water was pissing out of the weep hole. Swapped the water pump in under an hour.

Got the exhaust done last Saturday. I've been rippin around town all weekend. This thing goes! Im able to light up the tires all the way through 3rd gear, and theyre gummy bears (Proxes R888s).

The 4.10s keep the rps kinda high on the freeway, but im not complaining. Very happy at this point.

Didnt connect a ground on my front harness for the headlamps, and smoked my headlamp switch. So ill need to fix that and I also need to do an intake, which is in the mail now.

Snapped a pic of my exhaust before my phone died. Took them 4 hours. Tough to go over that grannys trans x member.

I haven't updated in a while because I've been out enjoying the car. Oil pressures have been good. I had a harness pin issue that was throwing two 5v circuit codes, that's been fixed. Had to relocate trans cooler. Haven't seen trans temps over 120f. And I burned a M5. Enjoying the car so far. Working on getting the smog done.

Used a combination of https://www.thirdgen.org/forums/ltx-lsx/544768-ls1-harness-start-finish.html and the Ucandoit2 YouTube series
.
Good luck.

thanks for the link. I'm comfortable around the LS wiring. I was thinking the merge to Mazda. Looks like straight forward from what I saw on norotors and rx7 club quick research. A very clean convertible (I think 88 or 89) popped up locally by me, so I'm tempted as I've got a spare motor/trans sitting in the garage.
