Pentastar V6 in a TJ

[Head Lice]

Pentastar V6 . . . Has anyone done this re-power to a TJ?
Wondering the pro's & con's of a transplant into a 5sp. TJ.
Keep your TJ 'all Jeep' . . .
Thoughts . . .

If I was going to put another 6 banger in a jeep it certainly wouldn't be that one

I'd ask WHY???? For the amount of work you coulda had a V-8....

In all seriousness are you talking about the 3.6?

Who rev's their engine to 6,400 RPM's on a normal basis? And the torque peak is way higher than most would rev to also.

Keep it all Jeep with a 392!

Don't forget about his little brother 354 ci.....

6 cylinders I'd use instead of that minivan motor:

Stroker 4.0
The GM inline 6 for the trailblazer
Toyota 2GR (this one's also a minivan motor but a way better one)

You two!!!!

As previously stated, why?

For the amount of work you're going to go through to install one you'd be better of swapping in a V8.

We have to remind @Head Lice of this fact every now and again...

I just highlight it with my mouse so I can read it, no biggie...

I can think of a V6 I'd like to have in my Jeep. Not sure that the front suspension can be beefed up enough to support it though.

I can think of a mechanical inline 6, that’s heavy, that I would entertain drooping in.

No “V”6, though.

Pretty sure Zorba is thinking of old GMC 305 V6

I've had the Pentastar V6 in a JLU and JT. I think they're pretty good engines but don't think I would put one in a TJ.

If I had a notion to do something it would probably be a 4.6L stoker. Maybe with the Edelbrock head to save some weight.

Here's a company that is offering the swap with an auto.

My 4.6l is a blast.the aluminum head almost makes it like the the winch isn't on there.

Starting with a gutted tj or 4cyl,I would be very tempted to do a GM 4.2l/4l60e with a low boost turbo. 100+ hp more than I have now and probably better mileage.

Though honestly I'd rather use a sprintervan 2.7l/nag1 diesel combo. I know of several near me with over 300k miles going strong and getting 20mpgs

If I'm paying that much for a swap it's gunna have 8 cylinders... Using the 8HP is a good idea...

Or at least something SICK like a 4banger with a turbo

I wonder what the difference is between a 3.6 & Hellcat is price wise?
