It looks like boostworks

Peter did you make the header? I have a question on the location of the wastegate. Is it going to be able to hold a low amount of boost being that its at the back of the header and only dumping one cylinder.

Kenny, as Tom said-- it's made by Boostwerks. They are running it very successfully on their XJ. (Link to build thread) I don't yet know enough about turbos to say anything about it. I am just feeling my way through the dark, right now. There will also be a blow-off-valve.

I have the dump pipe half fabbed up. Getting ready for the snow tonight (digging out & getting the plow on the Willys), so no progress...

That Guy has a really nice and detailed build thread. BOV is for intake pressure. Works with the throttle blade and vacuum. waste gate is for dumping off extra exhaust gas to keep proper intake pressure. your running a log style header so it might not be a problem as there not all flowing in a direction like my mustang headers where.

Exhaust manifold is done. Look like the body is coming off tonight or tomorrow for paint prep. The engine is going to get a little attention, as well.

So awesome!!! The tubing looks great! You have the oil supply and drain worked out yet?

[Jeep-Power]

Thanks Pete. The engine is out and will be on the stand in order to do the timing cover seal, crank girdle, and oil bung.

Peter, Your engine is the 4.2? I see a fuel injectors and a fuel rail. Assuming you did the 4.0 head swap with the entire 4.0 fuel system and ECU? What needs to be done to get your ECU and fuel system to work with the turbo?

[Jeep-Power]

Thanks Phil!

Rich, yes, a 4.2 with a OBD1 4.0 head & factory EFI. I am planning on going with a Haltech Sport 1000 standalone engine management system. My nextdoor neighbor is very familliar with that system and is going to be helping with the tuning of it, thankfully. Thanks again for the help tonight!!

Thanks to Rich, the engine is back in ( crank girdle, oil pan gasket, and turbo oil return bung) and the body will be off this week!

Preppijg for the 4.0 girdle


Because the 4.2 has a longer stroke, the crank/rods make contact with the girdle. It needs to be out about 0.100 or less. Some washers took care of that.



The CJ pan needs to be massaged just a little for clearance. The air hammer quick work of this. Used yellow layout die (the stuff used to check year contact pattern) worked great to show the contact points.



Note on the bung placement. 3.5" from the gasket surface of the pan is perfect. This will give you 0.5" between the bung and the top of the oil, in the sump.

Any time thanks for having me, always much to learn working with Peter.

What kind of numbers are you expecting this engine to pull?

[Jeep-Power]

Thanks dude.

The estimation is that it will have approximately 200 horsepower and 400 foot pounds at the wheels. It'll se some dyno time when tuning in the engine, so we'll get to see some actual numbers.

LUDICROUS power!

Chip, chip, chip...

Gusseted the rear cross member/tow point


Had to shim up the rear driveline mount 5/16" (took too much out of the crossmember and the T-case was hanging below the framerails) and put a 2º taper in the shims (Due to the increase in drop, it changed the mounting surface angle-- yeah, got to use the Bridgeport :D ). It doesn't look like much, but hours of work went in here. This is all final assembly, I hope!


Motor mount in & final
