Forced Induction Stroker?

[FlexinCherokee]

I am considering buying a Stage 3 4.7L Stroker motor from 505 Performance some time in the near future. I have the 4.0 H.O. in my '93 Cherokee currently. I have larger LS1 injectors, with the computer mapped for the them. If I do infact purchase said stroker, how will a turbo affect the computer if I do decide to mount up 505's kit. They sell an Accel fuel management kit for 750.00 extra, but my question is. How does the computer calculate load and how will it accommodate boost? I know it's pre-MAF, how would one go about "tuning" it once installed? Hoping one or some of you guys can give me a hand. Thanks!

How does 505 do it?

Who remapped your current computer?

The MOTEC system is the best, and makes the tune easy with a laptop pc. http://www.motec.com/m600/m600overview/ On a boosted inline 6, there is nothing better, and it is so easy to tune! eace:

I personally wouldn't buy anything from 505

AEM FIC would do just fine for a fraction of the price of a MoTec.

I have read a lot of horror stories from 505. Don't think it's worth the risk.
I'd do some quick research before buying from them. Cause everything I've read is that their work is shotty and their customer service is non existent.

I got a cam from 505 performance and couldnt be happier. Customer service was top notch and the cam works great. Mabey i just got lucky?

A master tech friend of mine did the computer mapping, i'll post the specs of the motor below. Not sure if it's the path I want to go down. The turbo would be extra $$$

What are you trying to achieve? If you want a turbo, why not just turbo your 4.0L? Do you need a new rebuilt block?

I can retune the stock computer for less then the FIC setup would be.

I would like to have a stroker motor in my Cherokee, no particular reason. Just to have a little extra umph, when I get into the skinny pedal. I'm not too fond of running boost for very long on stock internals. A stroker would come first, a turbo is just an accessory.

If you are ever up near philadelphia, let me know. I think that a supercharger stock 4.0L will surprise you. Unless you need a rebuild...

FWIW, I've put 8lbs on our stock 4.0L for over 44K daily driven miles with no issues other than some gaskets and our slipping AW4. Chad @ Fringe Development however is helping us take care of that. I just wish his valve body upgrades we're available when we first turbocharged our rig.

Unless the motor is in dire need of a rebuild, the stock 4.0 is very capable of handling some decent boost if properly tuned.

I have also yet to see a 505 turbo setup on an XJ?

Stage 1 or 2 Cam Kit

Is that like a 3/4 or full race cam? LOL.

*4340 single roller chain and timing set

single roller is known to fail with an upgraded valve train.

@Talyn: LOL! their stages of cams go from mild-ish to pretty radical haha.
