Re: Project "Rock Bottom" rebuild

Ok so these are the plans I've been thinking about for the additional mods for the jeep...hopefully to be complete by this late fall...

Of course the 3.7 rebuild...
3.73 rear gears
Front axel from a 4.7 with the 3.73 gears
OME HD lift kit
RR upper control arm kit
Bwoody sway bar links
180 thermostat
RR adjustable ball joint
Spidertrax 1.5" spacers
Fastman big bore throttle body
Strongjeff port and polish
Rotors and brake pads(slotted crossdrilled
3" exhaust (have to research more)
Super 44 muffler
Catch can
Magnum "stingers" balanced injectors
Jeep SOS coils
Stongjeff tune
JBA headers
Nitto Grappler G2 285/70/17
CAI

Not sure if I should go ahead and get a full suspension set from bwoody or not..

Any suggestions or modifications needed to be made to this list let me know...I am on pain killers so I maybe not thinking completely clearly...

Any other mods anyone can think of to get more powa outta the 3.7?

I'd avoid the stingers bro, go with a Ford 4.6 injector from the early 2000's. I'm running 4.6 cobra injectors from a 99 N/A cobra which are a 4 hole 24# injector. That's better then the stock 2 hole 21# ones we have. Plus airram themselves said to avoid the stingers. They are garbage.

I wouldn't do a full bwoody setup if you plan on being an off-road build. Most of their stuff is street oriented.

Have you considered getting the ATI Super Damper w/25% under drive? I feel it complements the 3.73's well.

Here's my feelings on the FM S44 muffler. Its garbage. I ran one for 6 months before the welds started rusting out. The black finish wears off after a few months. If you run it catless like I did, it just sounded hollow and soulless lol. It just wasn't a good sound. You can get a cleaner sound from a good glass pack.

If you keep it single exit, 3 inch will be perfect. Especially if you bump the compression

Re: Project "Rock Bottom" rebuild

Good advice..I'll amend my list, those injectors can be had for super cheap too!

I'm still torn with the exhaust situation though...I'm going to listen to some more sound clips... I know I'm not going to get that deep rumble like I would if the jeep had a v8 but I just want something close....

I haven't considered the under drive dampener yet, but since the engine will be turning more rpms at highway speeds with the 3.73's it makes sense....

What do you mean by "bump the compression"?

Lol...man I've been youtubing 3.7 exhaust just to hear the different setups, and sometimes how the guys put their cameras down just makes me lol....I don't know why just makes me laugh...sitting outside drinking coffee, smoking a cig and my neighbors think I'm crazy I bet...lol

Are you raising the compression from the stock 9.7:1 is what I mean.

Just YouTube my channel, I have a few different setups I've ran that have plenty of drive by In them. (Wot flybys)

Re: Project "Rock Bottom" rebuild

Here's a serious question, anyone try to retrofit an old powerdyne style supercharger to the 3.7?

Nevermind, read about the rings on the pistons and the pistons themselves...it's a no go...just a random thought I had...

Unless you go with forged ones......

sorry for the late response bro, just got back from the field and well my phone about blew up a few days ago....so I'm without a phone till tomorrow when I get paid....

take a look on airram's page, they carry forged pistons and rods for the 4.7. they will work in a 3.7 as they are the same parts. only difference is that the 3.7 has a touch longer stroke as this is due to the 3.7 having a split pin crank shaft. (meaning the crank pins are offset to each other. this is needed in a 90* V6 for smooth operation)

let me know when you want the manifold ported. I can also shave it to improve the look and do paint work on it

Re: Project "Rock Bottom" rebuild

It's all good man, I remember you saying you were going out into the field, hope all went well..

I'll look into the pistons, problem that I guess I'm really going to run into is the MAF...and adapting it to boost or might have to get something different...do you think that plastic intake will handle 5 to 8 psi??? That's another issue I'm thinking might come up..

I think it could handle 15# easy. its pretty thick material. and since our jeeps don't run a maf setup (MAP= "Speed desnity) we use a map setup which is actually easier to tune for. however, our factory map sensor is only .5 Bar (7-8 psi mark) I need to look into possibly a GM map swap. I'm planning a 10-14 psi build, shooting for 450-550 rwhp lol

Re: Project "Rock Bottom" rebuild

Damn...I'm not sure I'll need that much power myself...but if I could push mine to about 300 or more that would be more around my goal. And I feel like 5 to 8 psi would get me close to my mark.

Yes I would want you to port and shave it...I'll think about the paint..
