Has anyone here used a 2.0 LNF to power another vehicle? Particularly, a RWD vehicle?


Right now I am just at the concept stage, but as I am slowly crawling towards the completion of my current project (See signature), I'm growing more and more impatient about building something else.


I've settled on the next project to be a LMP. While the current LMP1's are a wee bit advanced for garage-builds, I think something to look similar to a close-cockpit Porsche RS Spyder. Some points considerd are:


- inboard suspension
- LNF power train
- 2 seats
- center lock wheels/spindles
- internal jack system?
- steel square or round tubing frame design
- fiberglass body


I considered a few other motors, such as the Hayabusa 1.3l, 4G63, and a few others, but from looking around, the 2.0 LNF appears to have a pretty good aftermarket supply, and can handle moderate modification without replacing internals. On the negative side, I'd much prefer to use a longitudinal engine placement, with a transaxle, but the Porsche G-series transaxles aren't exactly cheap.


Before I start working out framework on SolidWorks, does anyone have accurate measurements of the entire engine/trans/front suspension? I have not been able to locate measurements between engine mounts, correlation between engine mount points to the engine itself, dimensions of the suspension mounting points in correlation to each other and the engine mount...


Any information on that would be great. The other option would mean that I would have to wait until I could purchase a salvage Cobalt, and measure from there, but I suspect that to be about 6-12 months away.


Thanks

You have heard of the goblin kit car correct. There are a couple of threads on it in here. Basically you reuse the whole motor/trans/cradle of suspension and it becomes the rwd of the car. It also uses the brakes all the way around and a few other things. Might check it out if you haven't as they have a web page. If Someone rear ends my car that's the direction I will probably go.

 

Solstice, and i know one guy did a buggy with lnf

 

That goblin kit looks amazing I would buy one

 

3-up on here has done it with a smart car. Rwd transaxle setup with LNF and F35.

 

If I didn't have a 406 for my nova I would try the motor bolted to a built automatic. That would be fun and lightweight.thinking someone else already has done that.

 

Ive always wanted to put the LNF or even the LSJ in a fiero myself. Seems easy enough if you take the harness and ecu with you.

 

I think he wants to use a longitudinal transaxle

 

Id imagine the Sky or Solstice transmission would be the best, maybe the ATS and 6th gen Camaro 2.0T Transmission as well.

Regal, cobalt, verano etc are all FWD transaxles.

Edit: All of those transmissions would require a drive shaft and a differential, but would be cheaper than using a porsche transaxle, and could allow for the engine to be mounted slightly farther forward (or the differential and rear drivetrain farther backwards, which would help with weight dist but require more moving parts and a longer car or farther forward driving position.

 

No, I'll be content with transverse. I was stating I'd prefer longitudinal, but the cost would be much higher.

I looked at the goblin, and I'll have to talk to the guy and see what he did for rear suspension.

 

If I'm not mistaken the rear suspension is the front suspension on a cobalt. I think the whole carriage along with control arms bolt to the rear.

 

If that's the case, it'll work nicely.

 

I hope you can make it work. It will be a very efficient setup compared to longitudinal. Try to keep the stock LNF axles if you're able. They're nearly indestructible.

 

That'd be the intention--this would be as low-cost as possible, utilizing as much from the donor car as I could, although that would probably end at power train, spindles, and wiring/ECU.

 

I believe an lnf uses the ar5 transmission in the solstice

 

Don't forget about the Auto 5l40E. Can be built for for more power with 500$ in parts. Modify stock control module programming via HPT.
Although, these trans types would need much more real estate for rear/mid engine fitment
