Yeah, I know I am going to be banned for my TW in the PPB. But I figure if we group thread turbo's and setups instead of everyday we have a new turbo and tune then it will make the PPB less cluttered.

Back to the Top.

Your thoughts,
Car model year and WRX or STi
Power made (Dyno's please)
relevant mods
if you know boost, timing, afr's the better.

Swapped from the original green to the HTA, small increase in lag, tons more top end, night and day.

It's a good compromise between the green and red, and from my experience is pretty close to FP's claims.

Car made ~375whp with the original green @ ~20ish psi, (trap speed calculator), after the HTA, I made 20-25 more whp on the spreadsheet than before, on a relatively less aggressive timing tune with similar boost and AFR (11.5-11.0)

However, it's not exactly a fair comparison. With the HTA, I also threw on a FMIC and EWG. Full supporting mods, both were 3" inlet 8cm turbos.

06 WRX

swapped from the FP 20g td06 8cm w/2.4 inlet

spool is actually a bit quicker you can see this in the "official data log thread" Phatron started, a few variables are outlined in that thread as well

power is good, look at the "official road dyno" thread I made 420 whp with a half ass home tune, Phatron made 427 with a we are the top 2 in that thread both HTA greens, this is a lower reading dyno off of logs

power is good on meth, never run it on pump, don't have the $ to do a full fuel system overhaul to run e85 so 93+meth is what I am at for now

relavant mods: Outfront motorsports shortblock, turbo w/IWG, Perrin FMIC, headers, AMR maf, TGV del, samco 3" inlet, MBC, Meth, grimmspeed uppipe, maddad downpipe, 750 DW inj, fuel pump, Romraider tune, blah blah

boost around 24-25 max tapering to what ever my IWG gives me about 21-22, timing I have gone big timing and have gone less, not much difference in the 2 really

well, i havent really tuned mine out yet. i put the hta on and did a couple pulls on 91 and a couple on 100+meth and it was pretty good, but nothing startling as it only made 10 whp more than my og green.

I was having several problems tuning it on the 16 bit ecu
- My MAF was maxing at 5500 rpm
- The target boost limit in the ecu is 24.75 psi

I purchased a css fmic kit (big PITA dealing with them), then i added on a perrin blow thru maf, and then added a hallman mbc to get around the boost. But the car has been sitting for months cause my room mate is using my optoma battery in his truck.

im not in any hurry to get it done now since its so hot here. i wanna have it ready for october and get into the 10's

Stames, are you looking for a turbo that spools better or makes more power than your DOM 3?


Or both?

he already had a dom3 tuned on meth and race gas.....

dom3 to an hta green is too small a step imo.

need at least a stock location gt35 or red......the red would be my choice since its the same price as the hta.

Still waiting for my turbo in the mail. I will post my logs with the rest of the information...

No track on Oahu so no time slipThis will be on 92 with no meth. But I am looking into the hfs-6 maybe we can get a vendor to have a group buy for this item

In 4th gear maybe. But surely not 2nd or 3rd gear where you have less load.

Also, according to the dyno chart above your HTA Green is only making like 335whp - I think you might have an axis labeling problem.

that chart was on 91+meth with an ebay tmic. my 427 whp in the road dyno sheet was on 100+meth with the css fmic. for the road dyno thread i did not make the graph, i provided the log to the Leslie and he makes all the charts.

the graphed log doesnt match up with that chart.

the dyno chart was to show the hta vs gt12 vs 16g

the log was to show the boost.

my 2.2L with HTA Green and 6 speed doesnt feel that much laggier on the street than my 2.5L with OG Green and 6 speed. I mean its really all about what the individual wants. if you want low end put a freaking td04 on, mid-range use a green, top use a gt35.....every turbo isnt for everyone.

here are the charts leslie made. HTA Green first, OG Green second

My HTA Green is going on my car as we speak. I'll be sure to post up my plots when it is done. I'm anxious to see what it does vs the SZ55 I had on the car. I didn't swap to make more power, it just kinda happened. The SZ55 with the motor set up I have in the car right now made 350 on 93oct with a conservative tune.

I want a Z06... but that isn't happening. It is a struggle in my mind whether I want a little better transient response and sacrifice a little power or chill for 2-300 rpm and have a bit more top end. The Dom 3 spools faster than the HTA green ever so slightly. Nobody locally has the ATP 3071R and it was the turbo I was debating with when I eventually purchased the D3.

Here is my d3 up against the HTA Green. I am the dotted lines, Green is solid. Blue = torq, red = poewr, green = boost



Both tunes were done on the same dyno, same tuner, both pump 91+methanol, similar timing and AFR's and done within a week of each other. As you can PLAINLY see, the Green spools roughly 250 rpm later (big deal) but makes nearly 50 lbs/ft more torq and 40 whp. I am going to be getting the green, I am just very curious as to the ATP Turbo is all.

the 3071 would be lower and left of your dom3.
I think both tunes are conservative regarding peak boost and boost in general. Maybe kept down because you have a stock map sensor, but I push both my greens 4 psi higher on 91+meth. They both keep making power and still take 14-16* at peak

I know the 3071 would be another 300 rpm spool faster than the Dom3 and make less power. less rotational mass and lower lbs/min. I agree that both are quite conservative tunes on Methanol. We did do some pulls on 24 psi peak and tapering slightly on my D3. I made 363 torq and 382 whp. I just didn't feel that 2 psi was worth 20 lbs/ft and 15 hp so we backed it down a bit.

I liked the performance of my D3 and that is why the two turbos I was looking at are in the same ballpark. But I know I like a bit more power, so the Green is the choice.

so all you have to do is raise the dom3 2 psi and you have the hta performance....then why switch?

I initially like the turbo, but then experienced a failure, and after a lot of back and forth with FP (it was one of my worst customer service experiences ever) they finally sent me the upgraded HTA Green as a replacement - the results were more lag than the original Green and a bit more power but the DOM III performance was much better than both of the Green versions...

Ron, you could say the same about the HTA. No matter how you slice it, the HTA will give you a big increase in VE with negligible spool penalties.

Also, why are there 10 votes on the poll and only 4 posts from owners?

I'm gonna have to disagree with the DOM3 outperforming the HTA. Having ridden in a tuned DOM3 car and my HTA, both running 20psi with low timing on my car, the DOM3 will not outpower the HTA, but it will spool faster. I wish FP would do a BB HTA.

In theory that should work. We put in 104 octane race fuel and Methanol injection. Boosted 26.7 psi tapering to 24 at redline. Timing at redline was 29* and I made 398.5 whp. So the HTA Green with Less boost and WAY less timing (19* at redline and pump 91+ WI mind you, not 104 race fuel and WI) made 15 lbs/ft less torq, but 8 more hp.

The Green poo'd all over the D3

yeah, i understand that the hta will beat the dom3.

its just that on your comparo the hta was only at 380whp, which you said you achieved with 2 more psi on the dom3 and chose to take out the 2 psi and run it at 360whp.

i was just saying that if you just want the 380whp that the hta put out on that comparo to just add your 2 psi back to the dom3 and not hassle with changing turbos.

but with that said, i'd put the hta on too.

The Dyno comparison is a bit deceiving. It looks like the HTA is at or near 380 whp, but it is really 406 whp and 391 lbs/ft torq. You will notice the scaling is from 383 to 425 and that the peak power is about in the middle of the box between the two. with Peak boost 22.5 tapering to roughly 20 psi. Where I hit 340 torq and 367 whp with the same boost. That is quite a difference.

+ I have been a huge Advocate for the D3 and now it is overwhelming how many people have it. Which is fine, it does make good power and for the DD is a fun turbo. I just want to have something new-ish. Locally nobody has the HTA green. The consensus locally is that greens are garbage.

it is also funny cause I am an owner and posted and did not even vote lol

so there are 3 owner votes and 7 people who did not post if they really own one or not

I wanted a red, needed it with in 2 days, FP had the HTA in stock so I went that route, I am happy with the performance, it as you can see on your Cobb dyno comparo will handle a 52 lb turbo with ease, it was a great gain over the 20g I had
