Had a friend with a APR stage 3 ask if it was possible to upgrade his GT28r to a HTA version. So after making a phone call yesterday to Full-Race(FP dealer) I was told today that FP will in fact do upgrades to the GT28r. I guess this is good news so the GT28r owers since they wont need to change their turbo inlet setup after getting it modified to a HTA.

Quicker spool up then a GT28r and power like a GT2871r.[:D]

this is pretty sick, practically a 2871r with K04 like spool

So if this is done to GT2871R would you get spool like a GT28RS and power like a 3071R?

So this means they'll do the upgrade on the 28r, 2871r, 3076r, and 35r?

If it can be done to the GT28R, can it be done to the GTRS? And yes, this is good news as I was contemplating on peicing a GT28R kit together if my turbo ever calls it quits (or just get a used one). But if it can be done to an eliminator kit, even better. Can you maybe ask Full Race if they do it to an eliminator kit? Actually, I am about to email FP and inquire that info.

they will also upgrade a 3071r to an HTA3076r [up]

Yes, they replace the compressor wheel and compressor housing just like they do when they upgrade a GT3076r. So basically you go from a GT3071r to a full blown HTA3076r with the .70 a/r housing.

I am sure they could since they said they would do the GT28r. Problem is that the eliminator already hits a huge wall as it is, with a HTA 68 wheel it would hit that wall even faster because the exhaust side is going to be choked really bad. So the restriction is going to be the ATP elim exhaust housing since it has really restricted flow as it is.




So if this is done to GT2871R would you get spool like a GT28RS and power like a 3071R?

Not exactly. If you were to upgrade the GT2871r at this time the flow would not increase but the spool up would. So you would end up with a GT2871r that spooled like a GT28r but still make power like a GT2871r. This is because the HTA 68 wheel they offer at this time is slightly smaller then the wheel in the 2871r. If quicker spool but the same power is what your looking for then that would be an option. FP says that they plan on offering a full HTA upgrade for the GT2871r in the very near future, that setup would give you quicker spool up and power like a GT3071r.

Would the exhaust housing of the gt28r choke it off too? How much power would it be worth on a gt28r?

I dont think it would be really choked on a standard GT28r.

I think I always miss the point on this.. but any upgrade path for the 2876? It's going this winter, so looking at any new options... replacement obviously still the best one, haha.

Mike,

So you're saying it wouldn't improve power considerably but will improve spool?

imo seems like a waste of money to do on a turbo smaller then a 2871r.

Yeah. But at this point we wont really know till someone does it.

back from the dead...so let me get this straight going with a "HTA turbo" benefits would include: faster spool? currently have a 1.8T with gt3076 was considering getting this if it helps my turbo spool faster currently get 15lbs(only have my mbc set at 15lbs, because i'm on a stock block) at 4800-4900rpm. How much sooner would i spool with a hta3076 on a 1.8?

When I was running stock cams I was getting 20psi by bought 4200-4300rpms running a HTA3076r .82a/r

probably 500rpms sooner, but just a guess as that is what happened in the evo forums with the hta35r vs the regular...of course the 35r is a bigger turbo and on a different engine..nevermind, I'll shut up now.

There is a person on here whom runs the HTA GT30R (Militant-Grunt) and he said that it spooled 500rpm quicker compared to before he did the upgrade. I am not sure what RPM he hit full spool, but you can PM him to inquire.

BTW this post is a month old. I beleive Mikes account is still terminated. Here is the video of Militant Grunts pulls. I can't say exactly when he hits full boost, but you get an idea. On top of it he is not even bored out to 2.0. Very impressive.

I am definately going to be running an HTA3076.

at 15psi, you probably won't notice a big difference in power, only spool. Do some rods and bump it up to 22-25psi and you'll have a damn stout DD.

I was actually responding to the guy whom posted a couple posts up (the person whom bumped this thread)[cool].

I think he actually saw spool 700rpms faster. Nice upgrade if you ask me! Whatever turbo I decide to do here in the future it will def be an HTA!![up]

Wait till the Garrett GTX-R units are out[cool].

Hopefully, they will make them in the GT30xx series.

I've been hearing about these...aren't they just going to be HTA equivalents?

They look like they might flow better than the HTA units. Not only that, but these are manufactured by Garrett themselves (I am sure much more R&D went into it). Pretty sure they saw the HTA units, and would only want to make their own units better than another company did.

not only do you get a quicker spool. but you also get a more effecient air charge at the same PSI as you would with a non billet 6 blade wheel. which allows you to run more psi than an off the shelf GT turbo.
