4.6 Stroker Install

[RescueTJ]

Hello,

I am new to this board but not new to Jeeps. I basically have a built-up 2000 TJ that I have invested alot of blood, sweat, tears, and $ into over the last 10 years. With only 52K on it, my 4.0L gave up the ghost and I have decided to put in a Golen 4.6 after doing alot of research. I know these engines are both loved and hated, but for what it's worth it's the direction I have decided to go in. I have the Manual so for the obvious reasons I have decided to replace the clutch also when it is all torn apart.

I do have some questions I was hoping all of you can answer, or give advice on, based on all of your combined experience.

1) I live in Colorado at about 6500 feet and often take trails that will go to 13-14K feet. I am a little concerned about the possibility of detonation and wonder if I should initially install an adjustable MAP sensor to deal with this? I know I may not need one but I would like your thoughts. I know Turbo City has several and I am somewhat intrigued by the one with a 3 position switch.

Or... would I be better off using a custom chip and leaving the MAP sensor stock? If so is there a preferred/recommended chip amoung strokers?

2) I am planning on using a centerforce dual friction clutch. Any thoughts on this set-up? The Golen website recommends using a 4.2L pilot bushing. Will I need to do this with this clutch?

3) Is there any other tricks, recommendations, or anything else I should expect as part of this installation? I keep getting told that this is a pretty straight forward bolt in swap, but I hate suprises. I am ordering the 24# injectors from Golen as well.


Thanks in advance for any recommendations...................

The '00 computer is a lot more picky than the OBD 1 that I have so I suggest you go with the 27lb stroker injectors from http://www.fiveomotorsport.com/Injector_SetsJEEP.asp , add a Unichip piggyback module, and have it dyno tuned. Steer away from the MAP adjuster.

Thanks.

I got lined up with unichip now I guess I just need to decide which clutch is best. Has anyone had any problems with centerforce dual frictions?

My CFDF2 is still doing great. I had it for a year on my 94 4.0 and now it's been a year+ on the 4.6, so at least 25K of mostly city/suburb driving and I push my Jeeps hard and it takes it in stride.

I used a dual friction, center force in my 79 CJ with a 401. I like it. I used a Luk, gold series in my stroked TJ. I figured I didn't need the Center force in mt TJ, and price also played a part in that descision. No problems so far.
