Thought that sounded familiar. My roommate is a ecotec fanatic. If you're gonna build one of those skip the LNF and LSJ. Just grab an LE5 from a scrapyard and drop a stock turbo setup from an LNF onto it. Will be plenty of fun for an exo car without being expensive at all.
I already have a Cobalt SS with a LNF so thats what I would use as the donor. No way I would do a 2.4L with a LNF turbo. Thats a horrible combo. They peak power at like 5K and then drop hard. And they blow up past 300 whp. Ecotecs are my specialty. I have built over a hundred of them. The LNF is the way to go.
Ya I dont like the mac strut rear either... I really dont think it would be too hard to add in a top arm to keep it IRS but I would need to have the chassis here to figure out arm length, geometry and possible mounting points. It would pretty much be the same rear suspension as my Bug which honestly wasnt too hard to design.

The Ecotec is a great engine. It's used as a spec engine in a few small buggy offroad racing classes. They run them bone stock and kick the **** out of them without much issue.

You nailed it. 90% of my customers race class 5 and 10. They just now moved on to the 2.5L which is the next gen Ecotec but they are having issues with them blowing up. The gen before those were the bullet proof ones. Its pretty easy to get 300 whp out of a NA 2.4L too while keeping it reliable.

Ya in the older Atoms they put the LSJs in them. They dont make the most power but are super torquey. Thats why the last Ecotec I had in my Bug I put on the LSJ blower. Flat TQ curve from 2500-7000 rpm. Was awesome! The LNF in bone stock form holds 90% of its TQ from 1800-5300 rpm which isnt bad either. Its just you are limited on how much power you can make cause of the DI system. No one really makes aftermarket injectors for them and the HPFP cant keep up either. E85 is not an option....

Another motor option is also the LHU which was flex-fuel capable as well.

Magazine game is a lot different these days, especially with most of them being defunct or digital. I'll probably snag another one this year on my X actually. Changing up a few things on the car right now.

I read that somewhere, but the specifications don't match.
Torque claimed wet/dry boiling points of 683F/439F ( http://www.torquebrakefluid.com/comp...ke_fluids.html )
Prospeed RS683 claims boiling points of 583F/394F ( https://www.pegasusautoracing.com/pr...sp?RecID=10510 )

That's a typo on Pegasus Auto's website. I guess I can notify them to update their description. If you look at the picture of the bottle it clearly says 683 degrees Fahrenheit. I can see if I have a bottle laying around. I already have tested it on multiple track days and the pedal feel is streets ahead better than any other fluid.
