i habe a stock 89 xj limited, inline 6, 4.0 L. i just ordered a turbo kit but i was wondering, do i have to get a new crankshaft, camshaft, etc or can i use all those stock parts? i was planning on putting just 6 psi of boost in it.

any help would be greatly appreciated!!

 

Where did you find a turbo kit ?

 

No. You can keep your stock long block. Those probably aren't the questions you should be asking though...

 

i found a turbo that would fit and everything else. i have ordered it yet but im planning on it. just seeing what help you guys could give

 

If its one of of those cheapo ebay specials don't waste your time.If its from a big name company that is known like boostwerks i would trust it.But before you do anything sit down and do the math on how much its gonna cost you in the end?Theres a point where a v8 swap makes more sence,HP pre dollar can be a evil thing sometimes.

 

I thought about doing this or a supercharger, honestly as cool as it would be i would engine swap it and go from there.

 

Not sure if you're ordered it or not yet, because it's nearly impossible to translate your writing style. But it may be helpful for you to share a link to the "kit" you're looking at if you truly want advice. My guess is you never get close to doing something like this but please do attempt to entertain us. Also, I'd love to know how many miles are on the 4.0 you have now.

 

Im one of those people who started a thread looking to do it but have yet to do it, got the supercharger just have yet to make the leap.

 

OP should check this thread out:

This is what it takes to turbo a 4.0.

 

I'm curious as to what turbo it is also. Can we get the specs to how big or small the turbo is?

Ebay turbo kits are garbage, stay away.

 

Just dreaming.........................

 

We get at least 10 of these dreamers a year. I doubt even one in 10 ends up getting completed.

 

I rather have a blown ls but thats just me.

 

So true, they dont stop to think "Hey will my high mileage Renix era 4.0L blow up if i add this turbo to it with out fuel management or other needed mods?"

 

Actually, that wouldn't be a huge concern.

How the heck can they build and tune it if they have to ask about it?
