Cool Chicky's "Girl-Powered" 2.4 S/C'd Adventures

Hey guys, thought it was about time I make one of these threads as I am steadily/finally getting started on the unbolting process and already feel slightly anxious. lol

The "Beast" as I'm calling her for now, is a 2008 Black 2.4 Coupe 5 spd currently sitting on jackstands IMpatiently awaiting her newfound power.

Parts attained for this build thus far:

M62 blower
LSJ Intake Mani
Brand new gaskets for both^
LSJ Throttle Body
Bosch/LSJ Intercooler pump w/ pigtail (coming this week some time)
LSJ Radiator
42# injectors (coming Tuesday)
Idler pulley (not sure which one, need some clarification on this)
3 diff size pulleys (unsure of sizes, will have to measure and confirm)
Coolant reservoir tank
NGK Laser Iridium platinum spark plugs
Injen LSJ intake
LSJ dipstick
LSJ oil pan (for bonus +1 quart size)(thanks Mongo!)
Assrtd. hoses

Parts still needed for completion + tune:

_____<-- This is the blank I need YOUR GUYS' help to fill in. I've been reading all over this forum for weeks just to be sure I'm not forgetting anything but it's nerve racking feeling sooo unsure. I'm open to suggestions as far as getting this done. I'll be hard at work for the next 'however long' til my baby is back on the road again.

Sounds almost complete. Just a few more odds and ends. Finding some of the metric bolts can be fun

I got most of those included in my kit, luckily. And very nicely labeled in ziploc baggies even :-O so hopefully that shouldn't be too much of a problem.

TOO damn funny, LMAO! Where do you think I got my inspiration from?? ;-) My build is going to be strikingly similar to his but with my own touches here n there as I figure stuff out.

I just thought I'd open my own thread so I don't steal someone else's.

Intercooler pump mounting bracket
lower intake manifold bracket
LSJ 2.5 Bar MAP sensor (optional but reccomended)
Heat Exchanger
Wideband (optional but STRONGLY recommended)
stock LSJ belt ( cut one rib off)
Upper raidator hose
LSJ belt tensioner and bracket
LSJ windshield washer tank
Hardware (bolts etc.)


I see you have an LSJ radiator on your list. You will also need the LSJ rad fan assembly, because yours wont fit with the LSJ rad.
look at Becks Build for lots of reference material and supplies and tools you will need.

I'm pretty sure I have most of this stuff. Took some pictures just now, getting them uploaded so you guys can see what else I have that might complete the list a bit more. I've had my eye out for a decently priced wideband for a few weeks now, ever since I found the lovely Mr. Tjolley and his tuning awesomeness. No luck yet but I will definitely be getting one before I even start the Beast up once this is all finished.

I know that last one is an intercooler pump but I don't know how to tell if it's the right one. I assume because it came with my kit that it's a stock LSJ pump?

I believe I might have been mistaken with the mention of a radiator. I believe it's a heat exchanger that I have, I guess I'll take more pics lol. I only know I'm doing the pan swap for the benefit of having the +1 quart of oil. When you say 'yes it is!' do you mean it is a ic pump or that it is the stock LSJ pump? I ask because I just tonight ordered a Bosch pump off eBay because Beck's thread mentioned you needed one and a stock one would not work. Not really sure why the seller sent me a stock IC pump with the kit if you can't use one :-/

It works..and yes it is a stock IC pump. Not sure why it wouldn't work.

Yeah the radiator looking thing is a heat exchanger more than likely lol. What is the benefit of another quart of oil? Just wondering lol

I have the rubber piece you mentioned to go with the IC bracket. Good to know about the IC pump being usable, I guess I'll be retracting my purchase on eBay and saving myself $100 :-)

I read somewhere in Beck's thread a discussion about how having the additional cooling benefits of the LSJ pan with an S/C in the 2.4's being a bonus. Extra precaution I guess when I thought to purchase this.

Injector harness? So I got the harness but no injectors. How do I know which size injectors they will fit. I already have #42's coming on Tuesday with harness included. Hopefully I don't end up with 2.

If you want to run the stock heat exchanger, you will also need the LSJ rad fan. I know because that's what I had to do.

Thank you! No one has mentioned that thus far, didn't even have a clue I'd be needing that. I guess I'll be on the lookout.

What do you mean? like putting the stock h/e where the lsj have theirs? or putting it in front of the stock radiator. I just swapped a buddies h/e to the front of his radiator a few days ago. Wish I had a stock one so I could get rid of the zzp one lol

So this swap to the front can be done in my situation as well you're saying? I'd much rather do this if it'll save me monies and still benefits me just the same.

Not sure...my buddies is an lsj and I don't really know the differences between their cooling system and ours. Don't know if we actually need a extra fan for the radiator if we stick a stock lsj h/e in front of it.

Beck informed me that I'll be needing an intercooler. With the h/e, radiator, AND intercooler, doesn't it get a bit crowded up there in the front? I'm officially overwhelmed lol

Let's see if I can clear this up. I have the LSJ heat exchanger exactly where the LSJ's have it. So starting from the front it's: AC condenser, Heat exchanger, radiator. It might be possible to mount the heat exchanger in front of the AC condenser, but i can't be sure. Either way i think you need the LSJ rad fan to accomodate the tubes on the heat exchanger.

Also, the LSJ rad fan has two fans, where the 2.4 has one. You will have to source plugs and wire the fans so they each get power.

An intercooler is the same as a heat exchanger.

Easiest option: front mount heat exchanger.
Harder option: Stock LSJ heat exchanger.
Hardest option: both - that's what I have.

Space isn't a problem, as long as nothing is bent. All the LSJ stuff bolts right up.
