So i got a 96 XJ with a 6" lift 35's and a rack lol. not much mechanically done since doing a engine swap was my thoughts from the beginning. So long story short I got a 85 corvette for pretty much free. its got a L98 in it and i was looking to swap it in place. I searched on here (not hard) but I'm looking for advice on this build.

4x4 trans used?
any special motor mounts?
Tips and Tricks for the swap?

I have the whole vehicle so i was going to research more to see if any other parts are usable from the vette for Le JEEP

what trans in the vette ?

I'm not sure. if your asking if its a manual or auto, its a auto. its not a 4x4 so i havent put to much focus in it

ok, thx. i am looking for an early c4 manual car rear dif, that’s why i’m asking

Beatngyou27

do you know what 4x4 Transmission is compatible?

Have looked here yet? http://www.novak-adapt.com/knowledge...ick-gm/xj-swap
There is a lot of informtion there and they talk about the different transmissions and what is compatible.

thats a good Link I appreciate it. I'm thinking between the 4L60 and the 4L60E. the only reason im debating is because im not sure if having electronically controlled transmission would be compatible with the L98 ECU. I still have loads to research before i buy.

I also need to be sure that those transmissions can handle my goal HP. stock engine sits at about 230HP after I redo the heads, cams, etc.. I should be sitting about 330-345HP then headers and intake polish and bolt ons "should" be sitting 360-380HP possibly up to 400HP depending the route I go with everything. but once again this is just projected at this point.

I'm also trying to figure out how to get it mounted in the bay. I know its possible It's just rare.

I would like to do a LS swap some day. Going to drive the 4.0 till it either dies first or I decide that I need more power.

Don't quote me on it but I thought that I saw somewhere that a stock 4L60 was good up to 350hp. Otherwise you could rebuild it with stronger components to handle more.

I know that there are different adapter kits to get everything mounted up. I have only looked at this briefly as I am not looking to do it any time soon. Can't wait to see what you come up with.

Have you done any research on getting the fuel injection system to work correctly? it could be a real pain. not saying dont go for it im just saying thats the first thing that comes to my mind. its not exactly modern technology

Beatngyou27

if im using the corvette ECU and wiring harness how would it be a pain?

Beatngyou27

yea I read that its limited on HP stock, too but the 4L60 was highly recommended and also highly modifiable to my needs. so it was a good base.

I wanted to do the LS1 initially but I got the L98 at a steal. and complete at that.

with the xj or the engine? if you are going to swap a tpi motor in just to modify it...you’d be light years ahead doing an lsx swap right off the bat. also i would not suggest a 4L60 trans. i’m unsure of available space but at minimum i’d put a 4L80 behind any gm v8 i wasn’t keeping 100% stock and planned on driving like an old lady.

Beatngyou27

I read that the numbers weren't a direct correlation to the advancement of the transmission and that the 4L60 was better then the 80. LSX?

5-Speed

No the 4L60 is not better then the 80. I would take a bone stock 4L80 over a built 4L60 any day.

Beatngyou27

did more research and no im leaning more towards 4L80 for future projects. however since I already have the 4L60 with a stock engine I think im just gonna run it til it blows then I'll have my 4L80 on standby. but for now to save money im gonna run the 4L60.

I need to research now the transfercase that will work best.

L98-4L60-?-

And It's also a 4L60 not 4L60E.
