Mender, are you concerned about the strenth of the F23? Rated torque is 100 ft/lbs less than what the LFX makes. Also, is the bell housing bolt pattern of the LFX the same as the 2.0 liter Ecotec?



If you want a manual trans, you're basically going to have to ignore the stated torque ratings. FWIW, people are running 600+ HP 3800 turbo cars with the F23 just fine.

As for the bell housing, no, the High Feature V6 is a unique bell pattern. The Ecotec is yet another different bell pattern. The F23 mender is referring to though, is one that came paired with a Quad 4, I think. This pattern is also different, but close enough that it's theoretically possible to make it work with some fancy fabrication of brackets.

Mender, et al...

I am also considering this swap. You're going about it about the same way that I had planned, except that I'll be using a Beretta Getrag instead of the F23. (I posted in your LFX/F23 thread. Thanks for any info that you have shared.)
I may try to do the PCM myself. The Impala engine, with a manual Camaro tune. The worst that will happen is that it won't work.
I already have the victim, errrr.... car. It's an 88 coupe.
I won't likely be starting the swap until spring at the earliest. We are planning a move, and I don't want to take another car apart in our basement before that happens.

And yeah... the intake valve coking is something that has crossed my mind as well. Did you have to remove the heads? Or did you just remove the intake?
I've read accounts of people just blasting the ports with walnut shells, but that sounds like a bad idea, unless the valve is closed, and you can ensure that all of the debris can be vacuumed out. Afterwards, catch cans were highly recommended.

I took the heads off and disassembled them, glass beaded the valves, checked the guides (good of course), put in new seals, head gaskets, head bolts. I ported and blended the entire air path through the engine, from and including the throttle body and intake to the exhaust flange. I also baffled the oil pan and resealed it, after checking the bearings (new connecting rod bolts).

I build racing engines so I have all the equipment needed, and I consider working through a new-to-me engine fun!

The walnut shell thingy works, just make sure the valves are closed and you clean up thoroughly after you're done.

I have the opportunity to acquire a 2013, low miles, engine and transmission from a Chevy Impala, with ecm, harness, alternator, starter and some other misc. parts for really cheap. The engine seems to be a bit tall for the engine compartment, but a raised rear deck should be a simple fix. Anyone have input?



Centreline of crank to top of engine is 19.5".

The closest would be the Saab 2.8t (LP9 high feature engine) swap that bmwguru did on his car. I'm not sure if he's finished it yet though.



I have been so consumed with my shop over the past two years, I put the project on hold. I did shoot this video the other day when I blew the dust off the project. I plan to get it over to the dyno shop in a week and actually enjoy the car in the very near future. I love the way the car sounds and the engine really likes to respond to the throttle with minimal mods. I couldn't get the video to embed.

Nice! Hope it makes good numbers and you can enjoy it soon. Would love to see video of it on the road.

So what is the secret on this electronic solution to adapt this engine? Not much info out there on getting it to work. These motors are finding their way into miatas and classics. I called v8 roadsters (miatas) today. They want 1300 for their harness and ecu. He said they are making tons of them and they are behind. About 6 weeks to get a set. He said it should work in a Fiero. Just FYI.

That one was when I was running the stock Saab ecu, but I couldn't get the ecu to control the mixture and throttle the way the AEM does. It became a new car with the AEM ecu
