It sure looks like one! If the 2006 Wrangler 2.4 is a "fronty-backy" (i.e.: north-south) version of a Stratus engine, then it would stand to reason that a Wrangler block plus a Neon SRT4 engine = an SRT4 engine that can be installed in a front engine/RWD car like a TR7. Does anybody know for sure?

Reading wiki, yes. Actually doing it, I couldn't say.

I don't know about using a Wrangler block specifically, but installing a srt-4 engine in a longitudinal RWD arrangement has been done.

AFAIK, SRT-4 swap into a Wrangler has been done once or twice before.

Interesting idea. Any builds links?

See post 11.

"you can use the supra R-154 transmission for a RWD application. Look up the 2.4 Turbo Colt, I forget his username but he has an SRT swap in his colt running in the 9s. But basically you use a jeep liberty bellhousing which oddly bolts to the R-154, and that bellhousing bolts to the SRT block. IIRC you have to shave about 1/2" of material off the face of the bellhousing to insure full spline engagement into the clutch disk."

That's pretty cool, but I was thinking of SRT4 power for something small, light and RWD like an MGB or a Triumph TR7.

Completely possible. To make a SRT, just need the SRT rods and pistons. No need to rebalance either.

For another gearing option trans-wise (wider ratio spread, so not necessarily desirable for some applications), find a 2wd Dakota V6 from the 90s and take the AX-15 out of it. The Jeep bellhousing will bolt onto it. The AX-15 and the R154 are very closely related, most of the difference is in the gear ratios.

aka a $3k transmission because 2jz or 1uz all the things and a bellhousing that is super rare and usually about $750 if you can find one.

Maybe an AR5 from a Solstice/Colorado with the Jeep bell housing?

There was a super well done 2.0 Neon swap into a Midget I read about a few years back. The Liberty 2wd trans was what he used in it for his RWD situation.

The 2.0 and 2.4 are the same, a Wrangler and Liberty are similar, so I'd extrapolate to say "Yes" to your question

Yeah, an AR-5 should work too. MA-5, AR-5, R15x and AX-15 are all very closely related (and lots of internal parts swap too, so building a hybrid is theoretically possible if you can't find one with gearing you like).

Is the NSG370 six-speed worth messing with? There's a 2wd Wrangler I sometimes see in the parking lot at work and it's got the six-speed manual and I believe the inline-four. Not sure how great that trans is, but if this combination did hit the street, in theory an entire driveline swap should be doable with OEM engineering getting all the parts to line up.

A little research says you need an NSG370 for a KJ Liberty 2.4/2wd (05 - 07 should have had the 2.4 / 6 speed option), as that's the only Jeep that came with the 2.4 and 2wd (there was no 4cyl option for the JK Wrangler, and the TJ Wrangler didn't come in 2wd).

The NSG370 bellhousing isn't removable, so you can't just get one and put the right bellhousing on. And from what I can find, the 2.4 doesn't share a bellhousing pattern with anything else that came with an NSG370 behind it (Jeep 4.0 I6, Chrysler 3.8 V6, Chrysler 3.7 V6, Chrysler 3.6 Pentastar V6, Crossfire 3.2 V6).

So the NSG370 is an option, but finding the right one is gonna be tough. It's regarded as a pretty decent trans from everything I know and friends who have had them.

Internet also says that the 4wd and 2wd cases might be the same, but the output shafts are different. So there's a chance you could fine a 4wd 2.4 trans and a 2wd something-else trans and swap some guts to make what you need.
