XJ turbo idea

that sounds porn right there!

Well, from what I understand, researching the interwebs, the I6 in the XJ was an after thought. The XJs body just wasn't designed for an I6. Even with a stock car, a sub par cooling system will give trouble. There is no built in safety margin.
Turbos are, by their very nature, a hot bit of gear. The XJs engine bay cant really deal with this extra heat. Hence why a blower was suggested.

But, in saying all that, I have seen yanks slip jap turbo 6s into XJs. Dunno how they fair heat wise though.

And in answer to your original question, yeah, the HO 6 doesn't mind a bit of blow..... from what I've read....

Intentions are good but gotta agree with the heat issue.That will be your biggest killer especilly in the warmer months.After marker radiators and bonnet vents and even lifting the rear bonnet only help get under bonnet temps were they should be.Adding a turbo will be a big ask not just for engine cooling side of things but also the electricals under there would also suffer.

If it doesnt owe you much fab away, would love to see the results

tbh, i havent really thought much, if any of it, out as to where things would go/layout of the whole shebang.

so, basically im thinking the turbo would live either directly next to the intake and throw boost straight into the TB, or, low mount it underneath the plenum (heat shielded of course) and run some sort of FMIC but, that creates lag. so... its all thoughts and ideas at the moment.

post up some pics if anyones got any hey??

Mmmmm sweeet, sweet turbo


Okay, well as space and heat (reduced airflow) are your opposition I'd be suggesting you say goodbye to the A/C system entirely, that'd free up space around the manifold for the turbo assembly whilst reducing the radiator's airflow obstruction

Where were you thinking of fitting the inter-cooler?

i know it would be small, but the jeep isnt exactly a race car, so would be ideally chasing quick spool off idle and low rev type response.

what do ya reckon? worth trying or should i just not bother?

Its a different engine but the ford 4.0L XR6 Turbo only uses around 5 psi of boost in stock form and works great

I think this is mainly due to the straight 6 torque although the ford 4.0 does flow much much better than a Jeep engine

To the post super vs turbo it is all down to how both systems are set up, a smaller turbo that spools up fast will give low down grunt and with the jeep not reving much the loss in top end HP is not a big concern

Having said all that I keep looking at the super charged commodore and think they would make a great donor and apart from plenum which would have to be custom 90% of parts would be from the donor
