GoatBlower, I think I have heard you say that you are detuning yours, are you going to keep with the 2.4L and if so whats your setup are you going with, if you don't mind me asking?

Nope, scrapped that idea, I just simplified things for better streetability. I swapped my AEM EMS for a DSMlink and 2G mas and added about 300 lbs of creature comfort back into the car. The rest is the same:

-2.4 Eagle/Wiseco, no oil squirters
-1G head self ported, 1mm over ss valves, HKS 272 cams, Crower springs and retainers
-FP 3575
-FP race manifold
-Venom SMIM
-IRC race IC and my 2.5 - 3" piping
-3.5" Bushnut exhaust
-DSMlink
-1600cc primary injectors, 720cc secondaries(not really needed anymore)
-air
-power steering
-heat and AC
-navigation system
-blah blah :)

Andy, how much power are you shooting for? There are several of us with pretty good sized 2.4 setups on here. I am running an SCM61 on mine and can give you my setup if you want. I made 450 awhp on 25 psi and E85 at the last dyno day. Act quick and I could take you for a ride sometime soon.

I Just built a 2.4 last winter This is what I used:
2.4l 4G64 block
Wiseco Pistons
Eadle Rods
Main Gridle
ARP Mains
ACL Race Bearings

I used Motors by Gosh. He is a great guy to work with. The crank was out of spec so I had to get it ground down 10 under and re nitride coated. Regrind and recoating cost I think $400 plus I had him assemble the shortblock(I have had BAD experiences assembling engines). All in all I spent $1000 at motors by gosh and another $1000 at MAP for parts.

Like JET said, I also have a 6bolt 2.4 with over 20,000 miles on it. Stock mains here. PTE 3561 17psi on e85, no idea what power but based on a dyno from a couple years ago and my new mods and higher boost I would put it at at least 400+whp on a dynodynamics.

You people are a bad influence on me!!! all these high horsepower numbers are just getting me exited. It would be fun to ride in one to see the difference.

Since I just found this on Saturday, I really don't have plans for it yet. If I were to rebuild it, I would go with all forged internals (Eagle/Wiseco) just because then I would have a SOLID base to begin with. After that it is all bolt ons. I would want to keep it streetable and the reason I wanted to go with this engine in the first place is because it can handle a bigger turbo without so much lag time. Also the improve torque!

I don't know what to do with the head. I think that would be a key factor for this engine. I would think making the valves 1mm OS would help the 2.4L breath. I don't think OS valves hurts drive ability at all.

There was another thread on what cams to buy for a 2.4L and then after that I was surprised that Goatblower is running on HKS 272 which I thought would be a smaller cam for this size of engine. Maybe not with the OS valves.

Then after I hit a high HP I need to beef up the transmission, rear end, bigger breaks, Better bolt ons, SMIM, figure out if I can control this thing some how with a computer system (DSM link maybe).

Also I haven't done much research. However everyone is giving really good advise. Nice thing about this site, there are people here that have done this Hybrid and no one is spitting out complete BS on what I should do.

I will look into motors by Josh. Those prices sound really reasonable! Minnesota has a good Mitsubishi support.

You can always do the block and not put on the bigger stuff until you can afford it too. The 272's are the minimum cam I would recommend in a 2.4, Steve just had them from his 2.0 and transfered them over. The stock cams would work, they are just going to cost some top end.

I am still on stock intake mani, so that isn't even a must have. I say swap the block when you get it built, find a nice used SCM61 (or a new one), upgrade the fuel system if you haven't and drive it around.

I have 1mm over valves in mine, I am sure they help power a bit, but the stock head flows well. I would leave it stock until you are getting around 400 awhp or so, unless it needs a rebuild anyway. If you get up by fridley at all, give me a yell and I can take you for a spin.

I had HKS 272s in my car back when I went 10.4 and still had them later when it made 700whp at Elite.

I've had some FP3's sitting on the bench for months, just haven't gotten around to getting better valvesprings so I can put them in.

IMO, the oversize valves aren't really needed, but my goals were high when I started this project, plus I needed new valves anyways.

To upgrade to a 2.4, you really don't need to change anything else, but upgradeitis has a way of rearing it's ugly head. Weekly in my case.
