Hey EvoM,

I don't know if there's been a specific discussion on this, but I'm building a MAP Stage 2 LR 2.4L with GSC S2 cams, Ti Springs/Retainers, JMFab 02 Dump, Nisei FMIC, Nisei/JMFab IC Pipes, Curt Brown Ported Exhaust/Intake Manifolds, rebuilt head from MAP, 3" DP/Exhaust, Hallman Pro, etc.

With that said, I'll be running a stock IX turbo for the break in period of the build, just because I have it lying around.

Before owning an Evo, I've built several Mustangs, and thus like torque.

My goal is to be around 600/600 on E85, and around 500/500 on pump.

Ideally, the goal is to make above 500whp, and have torque greater than or equal to.

I can't help but cringe at all of these graphs of a 3586 setup or something of that sort making 200ft/lbs less than the HP output.

I know the obvious answer, ie. a Green (or stock IX turbo), but would like to hear other opinions.

How much of this is dependent on turbo choice and setup choice?

What turbos/setups have proven successful for you guys in making ample TQ through a 4g63/4?

Hta green is one the main Torque monster turbos I know of. I, for one, love the little lag my hta86 has compared to my old hta green. Up top, this hta83 blows the green out of the water!

From what I know, its the stock frame turbos that bring on the higher tq numbers. My guess would be the green. red or black??

Remember too, there are a lot of dyno results threads with 35r turbos on stock block, so the tq is purposely kept lower.

Im having MAP build a motor similar to yours and im using the EF3, going for maximum response/torque over 550WHP.

Your on the right path Medium sized cams, stockish head, Keep porting all your stock crap, No long runner exhaust manifolds, or aftermarket intake manifolds, Stock ported is generally the best options for torque.

If you go Bigger then an EF3/tred sized turbo theres a good chance the HP will be greater then the torque number.

Most of the stock frame upgrades will get you about equal hp and tq. The 2.4 will really be a tq monster too. Any T3 is gonna have a lower, flat tq level, esp on pump gas...unless you go with like a 30r lol. I'm the same way tho...I like the neck-breaking tq snap, and smaller turbos are where ur gonna get that from

This is one of my favorite power curves. Shape is like a stock turbo but the numbers are up where you're looking for...and it doesn't look like its at full potential for 93 oct either. Check out Curt Brown's HTA green results too...he broke 600 on e85.

You might wanna check out the CBRD turbos. They are really designed with quick response in mind. The bbk full will prob be too small for your power goals, but the bbk-b is the next step up. It's a bit bigger than the green, but prob won't spool much later.

I would start searching 2.4L results...there are plenty out there that are running on stock frame turbos of all sizes and they usually make tons of tq...good luck!!

It really is about the tune rather then the turbo. If your tuner knows how to make tq then reguardless of what turbo you put on there you will make the #s you want.

definitely keep in mind all the stock frame turbos. the BBK-B since its ball bearing now it can spool really quick and provide nice torque and power. although the bbk full made good power on AWD's Bastard (552hp/552tq) with e85. i say stay with stock frame turbo!

That sounds like a winner there!

I have 490wtq on e85 with my stock frame bb 7460r. More tq then I had on my jb Fp black!

Fantastic information. I suppose I'll just sell my T3 35r Kit and upgrade the IX when the time comes. I'll just have to decide whether I want an EF3 or EF4, or, Red vs Black. From what I've seen, even the EF4/Black can't keep even TQ and HP numbers.

Those numbers are great on that 3076, but I'll be on pump 90% of the time, and on pump the 3076 seems a bit lazy for my taste from the graphs I've seen on here.

^The graphs posted from Buschur were also done in 4th gear, which gives the impression of earlier spool then most graphs were used to looking at in 3rd.

I had a 3076 TS on my evo9 and the comparison to a stock frame as far as LAG and Low end torque isnt even close. For your goals a stock frame is your best option, glad to see you realize this already!

600+hp

iTrader: (5)

I had an AMS 50 trim turbo kit, did 175ft/lbs at 3000rpm, 350/ 4000, peaking at 450/4400.
final figure 470hp/450 with 28.5lbs boost. A/R .63
Swapped to 3076 HTA with ATP .82 A/R housing and MAP 3 manifold, everything else is the same. Dynojet diagram shows curve to be near identical with some spot differing by 50-100rpm with the HTA being a smidge slower.
519hp/47xtq at 30lbs
560hp/505tq at 34lbs. Tq is dialed down a bit because of my ACT 6 pucks which is currently the limiting factor. Gas is 92oct premium mixed with unleaded race gas with meth injection on top.
Motor is regular BR 2.3 with stage 3 head.
cams HKS 272/272. DO NOT want bigger cams
