What would a good mod list look like for making 330 awhp on a version 8 EJ207

Mustang Dyno

93 oct Pump

35-45 degress outside w/centeral connecticut elivation

I am not opposed to a FMIC but would prefer to leave the $$$ in my pocket and the JDM sti tmic I think is able to get me to my goal

Current mods.
Invidia n1 race catback
Custom 3" bellmouth catless downpipe
Ngk irridium 1 colder
Shell 93 oct. Winter gas
Walbro 255lb/hr
JDM Version 8 EJ207
TwinScroll IHI VF37

I was thinking at 22psi 300awhp with this setup. So maybe SMC meth kit, 850cc injectors, and a big MAF/intake will get me to 330awhp???

Voice your opinions all please! Thanks alot

Its depends. On the Mustang near me you would be looking at somewhere in the 270-280 range, maybe slightly less. Dont be sad, it takes a 20G+FMIC and 22PSI to break 300whp on that dyno, and stock STIs make @210whp.

Most Mustangs read a little higher. The BIGMAF will get you nothing if you arent maxing out your stock MAF, and with that turbo, no headwork or cams there is almost no chance you will.


A TurboXS/Perrin/APS tmic will make a good bit more power than the JDM STI tmic, honestly the JDM STI tmic is barely any better. Its the exact same core with like 3 more rows. That only makes it flow a LITTLE better, not cool any better to speak of. The power difference between that and a USDM sti tmic is pretty close to impossible to measure, and is well within the error of margin of a dyno.


You will make a little more power on that setup than you would a comperable single scroll setup, so compare it that way. You will however, make a lot more low end power and have better throttle response, slightly better than the 2.5L single scroll STI.

22PSI will be ok, but its pushing the limits of that turbo, sort of. At 22PSI I would absolutely recommend the SMC meth kit, but you dont need to spend the money on 850cc injectors, 750s will be plenty. Especially with the meth.

SMC is gone, and the AEM kit is cheaper anyway and has a few more and nicer features (including they VERY cool new pump system)

A FMIC is ALWAYS going to outperform a TMIC, but a quality TMIC will work very nicely with your setup, and is a little more New England winter friendly. TurboXS's tmic is cheap too, while still having a very nice core. Sell the JDM sti tmic and it offsets that cost a LOT.


I would HIGHLY recommend running copper plugs. You will only get say 10-12k out of them, and many people recommend replacing them when you do oil changes (3000-3500) but they are dirt cheap and have a stronger spark, that will hold up to the high boost better. I have yet to see a platinum or iridium plug outperform, or even perform as reliably as a copper plug. Plus you can run a stock heat range copper, which will perform better when warming up and I believe low rpm light throttle and cleaner emissions (dont quote me on that part about low throttle and emissions) Because a copper plug by its very nature will perform like a slightly cooler plug when compared to an iridium or platinum.

I would go with

TurboXS TMIC
AEM alcohol injection kit
750cc injectors
22PSI (Actually, I would do 23)
Replace everything in the intake tract in front of the turbo. You dont need a big maf, but if you can get one cheaper than a normal sized one, go ahead. Its not needed but it wont hurt anything.

I definitely wouldnt count on 330whp, and would place you more in the upper 260s, but trust me, it will be VERY fast, capable of an 11 if you drive it VERY well, especially if you drive to NJ and do it at ATCO. On a dyno like Andrewtech/TurboXS has, plan on 330-340 easily.

Amen Brutha! I got 275 whp with stage 2 on one dyno, then went to stage 3 and got 265 whp on a different dyno. But car is a hell of alot faster with stage 3, I dropped 6 seconds off my lap times at Willow Springs. Go figure??? Dyno numbers are just for bragging in the garage. What really counts is results on the track!!!

You will not make that power with that turbo on pump gas. Also, any turbo with a 7cm hotside on your motor is a mistake. If you want that power on pump, go with a 3076 or equivalent.

You definitely want to go with a different turbo on your 2.5L motor. The "body" of the HTA68 simply is too small and will choke off your motor.
Also you want a turbo with an 8cm hot side, and a large compressor housing. The 8cm hot side allows the 2.5 to breath, which not only makes more power up top (which is what people think is the only point) but MAKES MORE POWER DOWN LOW and improves throttle response everywhere, low, mid, and high. Its all about volumetric efficiency. You need a turbo that not only has a compressor wheel big enough to push the amount of air you want (the amount of air you want is directly proportional to the amount of power you want to make) but that the body is large enough to physically allow the volume of air through.


Also, the numbers you are looking to hit, simply are not going to happen unless the dyno you are on is so incredibly high that it is essentiall lying to you. The shop you choose can blow smoke up your ass all day about it being real, but I assure you that if you come up against a car that ACTUALLY makes that much power, you will get pooped on HARD.


Honestly man, TD05-20G 8cm will make you a LOT happier than that HTA68 for your goals. I would also HIGHLY recommend an EWG and maybe even meth injection.

That's a pipe dream. You're looking at slight over 350 on E85. On 93, you won't even come close to your goal. You're looking at an FP Green or larger to get what you want.

OK, Hi everyone just need advise/suggestions on how to at least reach a hit of 400whp on a dyno dynamics. My goal has always been to see a 400 whp # and so far I have always tried with only 91. I am throwing away my GT14 that only gave me 330 on 91 and changing to smaller TD05 20G 7cm2 which I plan on using higher octane/race gas on. Why, because I miss being able to drive my car on the streets LOL.

My mods are
04 STI swap engine, trans, rearend, axles,
TGV deletes
PE 850 injectors,
TD05 20G 7cm2 PNP/coated
APS 70mm CAI
APS 3 in inlet
Tomei unequal length headers
HKS EVC 6 boost controller
38mm waste gate
walbro 255
electronic 3in cutout
PNP throttle body
PNP intake manifold also Reversed
Custom FMIC for reversed mani
And at least 100 octane more if needed.
I am planning on getting a new block soon but am in no rush to let this one give the ghost. lol

Please let me know what else If anything I need to just see a SPIke of 400.

Thanks

That is also a pipe dream. Dyno Dynamics read low. You're gonna need at least a 50-55 lb turbo and higher octane gas to graze the 400 marker.

OK, great thing I posted it on here when first thing is to tell me a different turbo.

Lets do this........ Forget the dyno, what else on top of what I have do I need to hit or get even close to 400?

Come on! cams, meth,

You can't forget the dyno, everything depends on that if you are looking for a specific number of whp. For an example, I made 342whp with 29psi and E85 on a dyno dynamics with a 68hata. My dom 3xt-r is making 392 whp at 27psi, E85 and my 1000cc injectors are maxed, at altitude none the less. You need at least a dom 3, fmic, injectors, fuel pump, high octane, and high boost.

If you want to be over 400whp, I'd say go rotated gt3076 or dom 4 or higher and run E85. Of course to run E85 you'll need huge injectors (might as well go 2000cc), swirl pot, and prolly Bosch inline pump fed by one (preferably two) walboro's, new fuel lines, and a fpr perhaps. 400whp on a dyno dynamics is no joke.

A better answer? Seriously? Did you read the thread you posted? It was a freak, he's never seen a 20g make that much power before.

I understand this is the newbie section so I'm going to say this in the most non bashing way I possibly can. Since you clearly can't understand common sense, multiple educated answers, or any kind of research, I'd simply say throw a vf39 on there and crank the correction factor to 2 or 3 if you want a "500hp" car.

Ya, on an Dynojet that's reading even too high for a Dynojet. That thing made 377 on 91 octane.

400 is not a number you should set your goal at with a 20G. Why are you actively choosing to restrict your own setup and preventing yourself from using the easiest way to achieve your goal?
