LFX 3.6/F23 option (Page 11/13)

If there's interest, I'll look into it after I confirm that it all works as intended.

any updates?
mender MAR 22, 11:58 PM
No updates so far. Mainly wiring and exhaust to do at this point then it'll be time to see if it fires up and everything works. I need to find the time to work on it and it takes about an hour to get stuff out from underneath it so I can lower the hoist. Not easy when my shop is already crowded with customer projects and spring right around the corner.

I've been working on some of the smaller items like the Koni coilovers, Wilwood brakes and updated control arm bushings. Rear bumpsteer changes are in place but again need the car on the ground to check how well it worked.

sorry.. I sent this as a PM but meant to send it as a post..

Are you using the LFX ECU? Just FYI, V8Roadsters can provide an LFX ECU and harness without the dependence of a BCM, etc..
(disregard, just saw from another post that you got your ECU from Overkill)

What fuel pump are you using as from what I've been able to ascertain, the LFX ECU needs a PWM fuel pump.

Thanks for the heads-up, I was going to run a 255 Walbro but will likely check into a proper Camaro or Impala pump.

are you still going with the redrilled aluminum cobalt SS flywheel? or did you find a different solution?

I assume you're still rolling with an upgraded fiero pressure plate and clutch (spec or clutchnet)?

Unless you're okay with noisy pumps, that can't take the same abuse as a stock pump through my personal experience with a Walbro, stay away from them unless they have addressed that issue. Humming away in the tank at the back of the car is one thing, but right beneath your elbow may get old fairly quickly.

I had a Walbro in my Pontiac 6000 SEAWD back in the day. It was perceptible, but not noisy.
I have one in my Formula. It makes no more noise than stock and I've run it out of gas several times without hurting it.

Then you probably got an anniversary pump. Mine was loud and when run down to about 2 gallons at the usual refuel stop between FL and GA where the OE style pump was always trouble free, it overheated at the filling pump and wouldn't restart the car for about a half hour and by then I had already started putting my new inline pump on the car, which I finished in the station parking lot after a cop helped me push the car into a parking space. The noise level was night and day compared to the Deatschwerks pump that replaced it which except for listening closely, I could hardly hear.

There's also the balance between exhaust noise, if your exhaust is loud relatively speaking the pump is not. The only pump I used in a Fiero that was louder than the Walbro and not by much, was a Carter pump from PepBoys back before this website existed. It used a similar metal impeller system to the Walbro and was complete garbage, one was bad at install and another blew out its O-ring seal at the top of the pump. In the decades I've done this stuff, the older I get, the more I appreciate OE comfort and noise levels along with my horsepower and torque increase. It's just a heads up for those who are sensitive to it.

Yes to the Cobalt aluminum flywheel with six puck clutch disc and upgraded pressure plate. Another solution is a redrilled 3800 flywheel, I used that for some of my mocking up.
