The 703s flow 22.7lb/hr @ 43.5psi and are too big for a stock 2.5.

I know the bolt spacing is correct but I haven't tried them on my XJ. I don't think the backspacing will be a problem 'cause the rims are big enough to easily clear the brake calipers.

Yup.

You need these: Bosch 0280155712 19.4lb/hr @ 43.5psi

In my XJ, the screaming demon is usually the person sitting in the driver's seat. ;)

In that case check the TPS & MAP sensor.

My first thought was that the distributor might not be indexed correctly so I'd check that again. http://www.angelfire.com/my/fan/dist_index.html ___________________________________________ 1992 XJ - 4.6L Stroker - AX15 202rwhp 258rwtq (248/311 crank) Jeep Performance, Jeep Tech, Junker to Stroker

Chris Jensen is definitely still tuning Jeeps but he's apparently been very busy so a slow response isn't unusual. You could shoot another e-mail to [email protected] as a reminder.

Only do that on the intake ports & manifold runners. DON'T gasket match the exhaust ports 'cause they'll become too big and you could get reversion of spent exhaust gases back into the cylinders during valve overlap.

Yeah, I probably would have been cussing her with every expletive that I know. :laugh:

Stupid woman!

You'll need to have one custom made. Any competent exhaust shop should be able to make a mandrel bent 2.5" pipe for you. ____________________________________________ 1992 XJ 4.6L "Poor Man's" Stroker 202rwhp @ 4700rpm, 258rwtq @ 3400rpm 1/4 mile: 14.63 @ 94.38, 3450lb curb AX15, NP231, D30/D35...

Under WOT you'd need the AFR to be somewhere around 12.5-13.2 (0.85-0.90 lambda). An AFR of 14.7-15.4 (1.00-1.05 lambda) is the desirable range for light throttle cruise, and an AFR of 14.0-14.7 (0.95-1.00 lambda) is where you need to be for light throttle acceleration. ________________________...

Now that's interesting. Is it possible that the Renix computer isn't smart enough to adapt to the modifications?

That's probably true on '96+ models with OBD II and especially on '00+ models with DIS, but Renix and OBD I models shouldn't have any problem. The original 4.6L stroker build with the Crane 753905 cam ran absolutely fine in my '92 XJ with nothing more than larger injectors and a mild adjustment...

You'll have to build your own but it's easy enough to do with a few $ worth of Radio Shack parts, some automotive wire, and a soldering iron: http://www.angelfire.com/my/fan/MAP_adjuster.html

It seems clear that you have a fuel delivery problem so that rules out the PCM. Have you checked the fuel lines to see if any are kinked?
