I'm sure yes since it's the same design, initial impressions based on looks... The quality is awesome

Good projects for the weekend.
While the manifolds are off, closely inspect the row of freeze/welsh plugs on block. That's the time for replacement if needed (with brass).

Headers are in, manifold is in, and injectors are in!
Stripped the bolt on the FPR, oops... So need to fix that then install the steering pump.
I did get all the vacuum sensors hooked up and replaced the AIT.

So here's how it started, after I yanked everything out.
Old Headers were cracked in to places...

New Flow Daddy Headers... I test fitted them OFF the Jeep against the manifold. Then I proceeded to tweak them with a 9oz hammer. Numbers 1 & 6 both needed a little flatting.

Here she is with the Manifold in, I rerouted all the lines and hooked up the sensors, good to go.

Just one problem...
Here is the Old Fuel Rail

I learned about these things called pental caps and how my new 703's don't have any... So I found some online and should have them by Friday.
I'll be hooking up the new steering pump this week as well, going to use the Old Pulley vs a New One. The old one is about .25" smaller in diameter so a little fast flower rate.

Cool build!
I just ran into the same problem with the pintle caps on my 746 swap. Had everything ready to go and realized that no one local had what I needed. So I had to order the Bosch Type 3 kit online :/. In the end it was worth it and everything runs wonderfully.
Lastly, did someone say URE!?!

When I pulled my 703s from the JY I made sure to get the pintle caps as well. They weren't pretty but were still solid. Those injectors with a good cleaning have lasted me 3 years now and I'm averaging 17 mpg. Engine idle and throttle response are also better.
The plan is for URE this friday and saturday. Weather might not be the best but I'll be there either way. Hopefully your pintle caps will come in and you'll be able to make it

Could you post a pic of the pintle caps? I'm hoping to do the injector swap later this summer and that would be much appreciated so I know what I'm looking for at the JY.

Last night I spent a bunch of time trying to get the old pulley of the pump.
Got it off then realized I can't use it...
So just placed an order with Advance to pick up some new pulleys. (Replacing the Idler while I'm at it)

Well got the Jeep Running around 11pm on Friday Night:

All thanks to this package I got from:
http://www.bonanza.com/listings/Bosc...m_source=email
Bonanza.com , Seller: TurboCity, Bosch-Type-3-Fuel-Injector-O-Rings-Pintle-Caps-Ev6-Ev3-6-Cyl - $16 Shipped
They actually sent me enough parts to do a V8:



Here is everything bolted in and running:
99+ Intake Mainfold
703 Injectors
Higher FPR
Flow Daddy Header
96+ Power Steering
60mm Bored TB & Spacer


I'm thoroughly impressed, still have a few kinks to work out. I think the Flow Daddy Came with a not so quality Gaskets. It Seals at Idle but when the throttle opens up it sounds like a REALLY Bad Exhaust leak.
Didn't stop me from taking a trip to Uwharrie:
