The 68HTA is basically a billet 18G. You're never going to get far on pump gas with any turbo using a TD05H turbine.

Definitely won't be the Black.



Figure you'll need turbo capable of 52-55 lb/min to make 450whp on pump gas without meth in order to keep from melting things down. Unfortunately you can't have a quick-spooling DSM bolt-on pump gas turbo that is capable of 450whp....it just doesn't exist. You have to be able to sacrifice something:

- You can have a 450+hp DSM bolt-on turbo that spools fast, but you're not going to get away with running pump gas. (Example - FP 71HTA)

- You can have a quick-spooling turbo that works great with pump gas, but you're not making 450+whp. (Examples - Evo III 16G, TD05H 20G, FP 68HTA)

- You can have a 450+hp DSM bolt-on pump gas turbo, but it's not going to spool fast. (Examples - Bullseye S256, Holset HX35/HX40, FP DSM 76, Green XL, Red)

I figure a 2.3 should help spool things a bit faster than a 2.0 would.

I would be interested in seeing some dynos of the FP DSM 76 or 71HTA's.

Scroll to the end of the description:

Forced Performance Turbochargers: DSM Green XL

Honestly, now that I've seen those I may withdraw the DSM76 / Green XL as a serious contender. Under 400hp at 25.5psi on pump gas while spraying meth (which was apparently required to get above 22psi) is nothing to be proud of after shelling out $1400 on a new turbo.

Sometimes not as much as one would hope....and what you gain in spool you tend to lose in high RPM pull as you won't be revving as high as a 2.0.

My vote for a 2.3: Big t3 hotside. 37 series, 86 or 94. Maybe a 35 but i would still ditch the mitsu flange. Wont have to hit super high boost to come up with big pump gas numbers on a 2.3.

I am thinking that if I am going to start from scratch it might just be better to go T3, more specifically the 3076. I can get a good tune on pump and a nasty tune on e85, a set of fic 2150s, double pumper and go from there. The 3076 sure looks impressive. I won't opt for that ceramic coating though, that shop rubbed me the wrong way.

Justin while I won't argue with you because you know much more about this than I do but don't you think that writing off the 73 and 76HTA because of one dyno result is a bit quick.

AK Maniak said:

I know that on paper and real world results can vary greatly but with that being said those numbers seem incredibly low and not what one should expect from that turbo.

JusMX141 said:

Apparently FP was proud enough of that result to publish it on their site.

I wasn't as concerned about how low the numbers are as a whole because dynos do indeed vary; I'm more-concerned with the fact that the user needed meth injection to get to 25psi on pump gas while continuing to make power. That definitely shocked me a little.

If you weren't so hellbent on staying DSM bolt-on, the HY35 is totally capable of your goal.

ECMTuning User Support Forums

^ For those who can't view the Link forums, it's a 2.4L Evo which made 566whp/525tq with a HY35 running pump gas, no meth injection, and tuned by Link with a 2G ECU. Runs 10's on street tires.

Well this is all according to memory....for starters I was contacted by him and he said he wanted to do all of my coatings for free as long as I would kind of advertise for him. I agreed but stated that my car was still in Cleveland and that it would be a while before I got it back. I was asked how long it would be and I said that I did not know and that Ron had full control and that was fine by me. Ron Shearer and I are friends and he has my full confidence and cooperation. He said that was fine and to send the parts to him when I could. I got the car back about two months later and informed him that I would be sending the parts and was told to go ahead. I was then told he would no longer coat them for free as it had taken to long. I said I would pay for them but I should receive some type of discount as they were in the mail. Remember we are talking about some rather large/heavy parts so shipping was not cheap. I was told that there might be something he could do. i think the end result was a savings of like $50. I found the coatings to be so so in rearms of quality. I will now only have Swain do my ceramic and I use Justin at detective coatings for powder coating. He is in VA now, he used to be about an hour or so from my house but that will not deter me as his work is first rate.
