Engine swaps

The K-swapped NSX I think is owned by STMPO? And a v8 NSX has been in the making for many years now here. The main issue being how the drive train will be setup since the motor sits right in front of the rear axle. The JGTC NSXs used a longitudinal v8 with the transmission mounted in front of it, with a shaft that came back past a modified oil pan to the rear differential. Very complex in terms of a swap. This would limit someone to have an easier time with a transverse engine like the K20, or if someone wanted to, a transverse v8 from maybe a cadillac seville? Just theorys.
I think the key would be a built K-series. There is a Lotus Elise with a built K that is making 383 wHP, NA, on 91 octane.
That would work very nicely in an NSX. The engine could be placed lower, which would lower the center of gravity. Plus, there would be at least 300 lbs of weight savings.
The biggest expense would be the (custom) fabrication of motor mounts, proper shift mechanism and drive axles.
The engine build itself would be expensive, but a lot less than a comparable C30.

Yikes 383? How??? I need to know this secret!

383 na on 91 octane is impossible on any k series.
The motor is/was a 2519 cc (90 x 99) sleeved K24.

Its possible, just not on 91 octane with natural aspiration.

That isn't really an NSX anymore, that's something different entirely...
Not to say it isn't cool or awesome. Because it is both of those things. :biggrin:
Does anybody have a link for the K series NSX? I am very interested in learning more!
The LS4 in theory should be able to fit in the NSX. It will bolt up to the GM F40 6 Speed transmission http://en.wikipedia.org/wiki/GM_F40
If for some reason my engine ever pops I'll probably go that route.
Of course any mods that you can do to an LSx engine can be done to the LS4, so you could go well north of 300hp with ease.

I think a K Series NSX will be awesome once someone has a completely sorted setup. I drove the STMPO NSX at a Redline event. The car wasn't really ready and we didn't get a chance to compete. I did get to do some straight line tests and did all of 3/4 of a lap. The ECU had an issue and the car would fall on it's face shortly after hitting decent boost. For the brief couple of seconds I had at decent boost, it was very impressive. I'm also sure that it helped that the car was 2,000LB.
It would be nice to see Ross finish his car and get it running. I think money is pretty tight right now for him.
I've heard rumors of someone else working on a K series NSX. Hopefully we will see one running late this year or early next year.
Not without major modifications to the chassis, no.
You do have transverse trans-axles for the LS engine though.
We are fitting a dry sumped LS1 into the Pikes Peak NSX. All suspension geometries will be left alone, and the engine will be mounted 100% via subframes. With the use of a Porsche transaxles, a "kit" is entirely possible, though major fabrication is involved with clearancing the firewall and trunk areas, let alone wiring, exhaust components, etc. We have had interest in this, and are likely going to covert our "street" NSX into an LS-powered, fire breating monster.
I assume your going to run a Porsche transaxle with that?
Yes. Here's a shot while I'm configuring engine location. Dry sump pan allows excellent COG possibilities 
This excites people ??? (K20 crap)
A 4-cylinder engine NSX........... that excites some people here??????? - Give me a break, If I was American, I'd be swearing alot right now..... please go back to your civic forums and discuss k20 swaps there, there is NO place for 4 banger talk here.

As if the number of holes in the engine block was the only thing that mattered... or maybe you forget that 'we' can be on the lotus, 0-60 mph in "less than 2.3 seconds"Ariel atom, Track record breaking Radicals, and many more forums.
Are you aware of what formula one motors have in them? let’s keep that discussion to liters not cylinders?
And I’m an Italian American and I swear all the time… almost every sentence to be exact
Ian Palmers GTP(Australian race series) NSX had a transverse mounted Formula 3000 V8 engine in it for a short time. They blew the engine up in a big way & went back to twin turbo v6.
I'm with you. I can't get excited about a 4 cylinder NSX.
If I was to swap a motor out of an NSX it better be a much better V6 motor OR a V8 motor. I don't see how you can go from a 6 to a 4 .
