Ok so my current engine/breathing mod list is as follows:

Ported/blueprinted head
Cosworth M3 camshafts
Ported/coated manifold
LD19 headstuds
Manley valvesprings
HKS EVC VI boost controller
3" turboxs downpipe
hks carbon-ti catback
ARC induction box
DTM 3.5" FMIC
Wahlbro 255 fuel pump
AMS UICP and LICP piping on the way
880cc injectors yet to be installed
hks camgear for exhaust only on the way

I want to mod for now and later and later the only thing that will get done is a cosworth 2.2l stroker. The car is going to be used for road course track days so I'm more worried about area under the curve than I am horsepower. I am between the FpRed and a 50-trim type of turbo because right now my camshafts are moving more air than my turbo can keep up with.

Hp goals: I want to make somewhere between 400whp-450whp on pump gas with the 2.0l setup (if I make a little less than my lowest or a little higher than my highest I won't mind) on a Mustang Dyno with around 25lbs of boost. As mentioned earlier I'd be happy with 370whp as long as it came in at a decent rpm, however I'd be happier with 400whp at 6k rpm with a fairly flat dyno sheet.

Spool: decent tq from 3500-5k and if I get full boost by 4500-4800 rpm I'd be satisfied.

Future: I just want to to work well with my 2.0L and amazing when I go 2.2L.

With these facts which one would you choose? Alcohol/Meth is NOT an option for me. I am willing to run 110 mixed with 93. I would like one that works within my range with 93 though just in case. I am also not willing to use nitrous. If my goals are not possible you can state that as well.

red...only reason i have a 50 trim is that the kit including tubular mani/wg/turbo/etc was 600 cheaper than the red turbo alone lol

Reds rape 50trims. The 50trim is pretty much obsolete now.

I hit 30psi on my Red at 4100rpm and it pulls like a raped ape to redline. Reds are proven 9 second turbos. Reds make way more power than any 50trim I have ever seen.

This statement doesn't make sense. Either you want full boost by 4500 (which would put you into 35R or greater territory), or you want decent tq starting at 3500 RPM.

The FPRed and 50 trim are somewhat comparable turbos. I currently run a 50 trim with all the trimmin's so-to-speak, and if I had to do it over again, I'd go with an FPRed, as it is the cheaper option and potentially performs slightly better.

Correct me if I'm wrong, but if I'm not mistaken, the FP Red can flow 54 lbs/min while the 50-trim does around 450 lbs/min. Very substantial difference. The Red probably spools even a little quicker than the 50-trim so its win-win. The 50-trim is pretty much obsolete, unless you can find a killer deal on one.

kinda off-topic but be careful with those Cosworth cams. They seem to be having serious quality control issues, even reports of cams snapping in half.

A 50 trim flows about 50 lbs/min and the Red when it came out (from what I remember FP saying) was rated at 56 lb/min. I think many have showed much higher airflow than that though. So, it isn't as big a different as you quoted above, but still a different ballgame.

I would recommend an FPRed over the 50 trim.

yeahi called cosworth before I installed them and they didn't have more than 2 cams actually sent back. It was a tune/build issue with certain shops.

There is no reason whatsoever to choose a 50 trim over an FP Red. An FP Red outspools it, outpowers it, and costs far less in installation necessities.

Unless you are planning to mostly run really really short technical tracks, I'd go with something more like a 35R, especially given your stroker plans. The road course is not an autocross. You will nearly always be above 5000 rpm so having power down low isn't nearly as important as top end.

First Choice, Red
Second Choice, HTA 35R (I like the 3586)
Third Choice, PTE 6262 BB

I have a non ported Red and when I upgrade, I will be going with HTA 3586

Yeah, I think what I'll do from the advice above is buy the red for my current setup and then the 35r later. I don't want to make that huge a jump in horsepower from a red to a 35r just yet. I'll get the red and some more seat time to improve the driver, then go all out with 35r and cossie 2.2l stroker. Thanx for all of your help.
