Question on replacing a blown motor......

[TimH]

This is on a '98 Jeep TJ. Currently has a blown 4cyl engine it. How difficult would it be to swap in a 6cyl from the same year?

I would be concerned the transmission would not be a match.

good point... i guess that's one of the things i need to research.

It's alot of work. The motor mounts have to be cut out. You need another vehicle to rob parts of frame and graft back in. Once u get the motor set in then there's the tranny. The one in it right now is made to handle the 4cyl not a 6cyl. So your gonna need one of those. Then working our way back we come to the lil rear end they put in the 4cyl. It's got to go too. If you can find a rolled jeep or one that's totaled it would help alot. The up side is that you can have your lil 4 cyl rebuilt for about 1200 bucks.

Long time ago, but i had a CJ5 that blew the 4 cyl in it and i had a Chev 350 dropped back in it. Not a lot of problems with parts from Advanced Adapters. Talk about a CJ that would haul it!

I like the idea of $1200 the best at this point.

Sounds like the best option to me too.

A buddy and I did the same thing back in '99. We dropped an LT1 from a '96 Impala SS into it, kept it 4WD, and kept the suspension the stock height. Swapped in the auto tranny from the donor car, put the transfer case on to the transmission with an adaptor (advanced adaptors), put a Ford 9" out back, and did a few minor tweeks to the engine.

Once it was all said and done, a LOT more money was spent than what was originally budgeted, but it was scary fast (good power in such a short wheel base raises the pucker factor when you nail the go fast pedal), and gas mileage actually increased to 17 mpg (up from 15 mpg highway).

the actual reason for my original post and the number one thing i'm hoping to avoid right now.

but very cool though and would be fun to build i'm sure.

Just get the stock 4 banger rebuilt. It's a LOT cheaper. When my buddies Jeep was finally done, it had taken almost 3 years to get it reliable.
