Hey all, since the 2.0 exploded in my eclipse I've decided to build up my 2.4. Here's what i have so far:

98 eclipse gsx automatic
7 bolt 2.4l block/crank
7 bolt 1g head/intake manifold
Wiseco forged stroker pistons (9.3:1 CR)
Eagle H beams
ARP head studs/main studs and dowels
Fluidampr crank pulley

For the time being the engine is going together with an Evo 3 16g that I had for my old car. I'll be running it on the FP race manifold. But I know thats a little on the small side for what i'll be running, so I was looking at suggestions as to what i should save up for in terms of an upgrade. My goal with the car is it to be a street car, and have as low of a spool as possible while not taking some monstrous injectors or something. My current fuel system upgrades are 780 PTE injectors, FuelLab FPR and a Walbro 255. I plan on running pump gas only. Any suggestions are appreciated. I like the idea of the BW EFR 7064 but it's pretty expensive and i'm not sure if that'd spool quickly on my setup or not. The t3 single scrolls are much more affordable, but again i'm not real sure about the ideal size.

I'm open to any suggestions really, obviously I may need to upgrade other things for a turbo upgrade but I understand that. I just like to see what kind of turbos would be best for my needs.
 
2.4L should help spool a little quicker, and you want to stay within 780cc injectors, walbro 255, and pump gas. At 80% duty cycle, those 780s can support you up to 45 lb/min of turbo flow and keep you just under 400 hp.
Fp Black is going for around 800 bucks and can handle that for example. You can get ball bearing or other turbos, Depends on your budget and future goals. Keep in mind there are other turbos, but i figured you want to get max potential out of your fuel setup, with a proper tune. You will need more fuel if you plan to go higher boost from these turbos. Many choices out there but FP has great deals right now, check em out. As for spool, is this mostly a street setup and daily as well?

That 2.4 is gonna be a sweet setup man :thumb:

FP black is a bit overkill. An old school Fp green would probably suit you a bit better in terms of spool and hp!
 
I would not stay standard bolt on mitsu housing with a 2.4. It will choke up top regardless of compressor housing. A T3 or FP hta 30r would be the smallest I'd do and even then your looking at 450 to 500whp on pumpgas.
 
I'll check some of these out. To answer the question Phantom asked, yes this is a daily/street vehicle at the moment. I do plan on picking up another beater as soon as I can though because i only have 104k miles and I dont want to rack up a ton of mileage on it.

I have heard that the mitsu exhaust housing is a limitation. But in regards to that, would a t4 be too large?

Cam wise I was looking at GSC S1's, or possibly saving up for awhile and getting a Kelford 272/264 combo.

Depends on the turbo :ohdamn:

As for your cam choices, you can get away with far longer duration than that. A 264/272 combo is going to be restrictive on an engine with that much VE.

Get a set of the Comp Cams that were the FP3's. That should make a nice breathing beastly motor.
 
It's a shame they stopped offering those directly, now FP's offerings are either too small or too big for what i'm looking for. Not a huge deal i guess though.

I think it was because too many people were just buying them from Comp, so they stopped selling them. Call up Amber and ask what the comp part # is for the FP3 profile.

Just remember, you'll have to upgrade your valvetrain to a higher spring pressure to be able to not float valves, due to the high ramp rate of these cams.
 
Im running a T4 HTA3076 on my 2.3 and have enjoyed it this far (just got it back). I dont know that the 1.06 A/R (twinscroll) was really necessary but Ill say that the car runs damn good and is pretty gnarly on the street. My power numbers are slightly decieving but honestly I dont mind, the area under the curve speaks for itself.


FWIW:
Im all for a HTA3076 with a 2.4, you will love the spool, but of course my opinion will be bias. You might really enjoy the evo 3 / 2.4 though, it makes for one hell of a kick, but it likes to eat transmissions too. My evo 3 16g on my 2.3 produced a bit better torque (~20 ft-lbs more) between 3-4k rpm and similar power to my hta3076 in that range, thus the transmission eater comment, but after that the hta3076 kills the evo 3 in every way, the area under the curve is fantastic with the hta3076. I would definitely urge you to look at the bare minimum of some larger base hta3076 if not something like the hta3582.

Good luck and keep us informed!

I thoroughly enjoyed my 3582r HTA in a T3 .82 A/R format on my 2.3. Was an absolutely ORGASMIC turbo.

There you go OP, these responses give you a couple of different options to consider! I would expect that a T3 .82 A/R 3582 would be a great way to go as well. If I wanted a bit more power without sacraficing all my spool I think that is the direction I would head!

Well i was not sure about your plan, but since you are getting a daily driver soon..will you make this setup a weekend warrior? With the cam setup, and if you have about 2k for turbo and manifold setup, then i agree with the guys the 3076 would be nice. For almost the same price though you can get a 3582 or 3586. I know guys bit overkill, but with bigger injectors and management, you got yourself a killer future setup. If not the 3076 would be awesome quick spooler.
Check out michaels thread and email him and see if he can make you a badass deal:hellyeah:

There is a lot of truth there, the hta3076 isn't much better in price than the hta3582/86, good point Phantom.

Yes sir. A 3076 flows 59 lb/min compared to a 3586 flowing 75lb/min for almost the same price, you cannot pass that up. Bit of sacrifice but will pay off in future once the "more power" addiction feeling kicks in, without having to upgrade again :hellyeah:
 
If your using pump gas the 780's will do you fine. The trend now adays is to run enormous injectors on cars that make 400hp. I've never ran a 3076, but I honestly don't see the point of you going bigger If you are staying on pump. The 3076 isn't very big by today's standard, but its not exactly a little blow dryer pping hot air.

A tdo6 variant of the 20g or an hx35 would be nice too. You should probably go t3 with either of those. I really like the 20g wheel. It really blows my mind what the little Mitsubishi super back wheels are capable of compared to these newer wheels.

A 20g with the highest flowing exhaust setup(like biggest housing) you can put together would be the best for ## goals in my opinion. I have had lots of different setups on my dsm's, and some very powerful cars too. But at the end of the day the point is to have fun driving it regardless of power. And in my experience a td06h 20g is the most fun I've had with a dsm. Btw I love the td06h in a 6cm, but I don't know if that would play as nice with your big motor.

I was thinking HX35 as well. The 16cm2 twin-scroll housing in a proper twin-scroll setup would be killer spool up time on a 2.4, but still have great top end. It'd spool like a 14b/16g, and still have room for 500-600whp.
 
Some good info, a 3586 is right at the price i was assuming i'd spend and looks like it'd be a nice performer as well. Oh and I forgot to post that I already have BC springs, titanium retainers, and 3g lifters to go into the 1g head. So as far as I know i'll have the valvetrain necessary for all but the most extreme setup. I was also looking at possibly picking up some evo rocker arms, they are a good deal lighter than dsm rockers. A whole set of evo rockers weighs as much as a DSM set minus one rocker.

And I also dont get the whole giant injector trend, unless you're on E85. Arent you just sacrificing atomization for fuel volume for the most part? I know this doesnt apply to stuff like ID injectors and newer designs, but as far as I could see in my research the 780's are plenty for me right now.

I'm also running link v3 and a 3" GM MAF so i shouldnt have any issues with outflowing the stock maf or with any sort of setup I could want.
 
FWIW, I'd skip the MAF and go SD, make the jump now and never look back IMO.

Don't forget to take lag into account. The larger the compressor, the more mass it will have, and the slower it will accelerate.

I also agree that it would be best for you to switch over to SD as soon as possible.

I'll swap to sd once i'm more comfortable with tweaking v3. I ran v2 on a mostly stock car, so I dont feel 100% confident in my ability to make small adjustments to the tune on it yet. With so much of an investment into the setup I want to make sure that I know what i'm doing.
