Question 400-450whp on 93 pump turbo suggestions

Looking for a quick spooling stock location turbo that can hit around the 400-450whp range.

Obviously including all supporting mods and on 93 pump gas what are my options? Was looking into the FP Green HTZ but it seems people can barely crack 400whp on pump gas.

You want a bolt-in or stock location turbo kit that uses a Tial turbine housing? This will give you the widest powerband per turbo size, but the downside is that there are modifications to the block necessary for fitment.

Yeah I’m looking for a direct bolt-in no modification like the FP Green I mentioned. Thanks for the info though.

I would check out the newer Cobb turbos then. They seem to be getting excellent reviews.

Yeah they only turbos from Cobb I found were for 2015+ Subaru’s. I got a 2005 Sti but don’t see why it couldn’t work.

Yeah I kinda figured. Only reason I questioned it was because on Cobb’s site it says it wasn’t compatible.

I have a 2.5L and am using a ATP 3582R. It is a stock location and would recommend the external waste-gate setup. I am making 468 whp on 93 and 508whp on 103. Dynoed by Jermaine at Turboxs in Gaithersburg, MD. Good luck with your build.

How’s the lag on that thing? Those are some really good numbers.

I'd ask Justin North about the FP turbos, if you are considering oem style mounting. Lag is going to depend on the entire setup, no way to get an close comparison for that unless you are doing an identical build with all same parts and tuner. Turbos that size are a big jump from the oems. You really need to use the most efficient intake and exhaust path possible, to help minimize lag. I recommend the KillerB header if you're staying stock location, the path from the exhaust ports to the turbo are designed to keep the gases moving quickly and keep turbulence to a minimum. I have the spoolinator kit, which requires some grinding on the rear corner of the block to clear the compressor housing, but it's not a huge deal.

so. if the fp green will barely get you to 400 then you need something bigger. problem is there is no magic turbo that will spool quick and give the power you are looking for. its kinda the compromise that we all have to deal with. if you are thinking of doing a spoolinator I would also consider going rotated, I think there is more potential there. The spoolinator is a really cool kit, I do have one by the way, but in hind sight, I think a rotated kit would have done the job as well

1000cc injectors, 450 pump intank. A slight mod and it fits . The amr t60 with 9 blade turbine and gtx billet compressor wheel, 26 pounds boost, stock location no mod needed. Full spool at 3500 ish. Turbo is a little bigger then a 3076. 65 to 70 pounds a min with the 9 blade turbine and 30.1 compressor wheel. Its basically a modified Mitsubishi turbo. 20g . If you want a little better spool put a 25 shot of nitrous on it. Turbo lab has mjthe turbine wheel and compressor wheel.
With the turbo all stock . No modifications to it. 1000cc injectors, dw 35c intank, stock header. 22 pounds boost. Car made 352hp on conservative iag tune. Only a cold air intake on the car ,turbo inlet, and p&l exhaust. Cated downpipe.

I never dyno the second set up when it was on 26 pounds. I changed the header, uppipe and went catless. Went externally gated. Change pumps to the 450. Then modified the turbo. All the numbers looked good s o i did not change the tune. The car had to have over 450 hp or close. I raced alot of cars over 500 hp and won. So i really have no clue what kinda power i was making.

I have had extensive head work done and am using JUN 270 camshafts. Its a hybrid and has been stroked to 82mm. The torque is 488 ft lbs on 103 with WHP at 508. The ATP 3582R is all in at 4000rpm and I am running 21 lbs boost I have attached my Dyno chart for you to see the 93 and 103 numbers. Of course the mods required to support this level of whp have been done also.

Correction. All in at 4500 but with the setup you are already back in the seat from the massive torque.

My fp green put down 450/400 on a Dyno jet with 94.5 octane. Put a splash of torco in your 93 to make your goal if needed. Fp green is hard to beat for the dollar. I took a cobb off to put the green on. I've since upped the octane to 99.5 and got 520/460 out of 27.5 psi, 11.5 afr and 10/20 timing

HTZ Green will get you there if the right supporting mods are there. I made 433/401 on a MD at 25-26lbs. Next motor took a ton of timing out of it for safety and made 401/373. This thing really likes high boost and ethanol though. I made another 100wrq and 80whp on E70 at 30-31psi and the tuner said he barely touched timing. I'd 100% go with the Green.

I'll ditto going with the FP Green HTZ. It's a good stock location turbo and is rated to flow 61lbs/min. I have it on my hybrid engine and it does full spool around 4k RPM with UELH. On ELH, it's probably around 3.7k RPM.

Yeah I talked with my tuner yesterday we settled on a green with the Cobb flex fuel kit. He said he’s tuning a blue soon so that will be interesting to see results. But thanks for all the info guys.
