If you roll back through this thread you will find a thread about some guy 'back-to-back'ing a range of turbos on some kind of Audi.. Posted by Lith.

From memory the test list is as follows:

- GT3076

- 3076HTA

- GT3582

- 3582HTA

- Some PT thing

So putting my understanding of those results together with results I have seen elsewhere; the 3582HTA packs the usual 35R punch for outright power but brings response back towards the realms of a garden variety 3076R.

Elsewhere I have noted that a 3586 seems to keep things on the '35R' playing field in terms of response but packs a heavier punch with more outright power.

So in your case you could make the following generalisations:

- 3582HTA = better spool than stock FG turbo, as much power (if not a little extra due to larger comp housing) as BA/F stock turbo

- 3586HTA = BA/F stock like spool with more outright power

(for the uninitiated following this topic the FG turbo is a 3576R and BA/F is a 3582R, both with .50ar comp housing)

I hope that helps.

Beat me to it, GTScotT :-D Comparing response between the HTA3582 and a HTA3586 is not like comparing with a normal 3582

Cheers for sharing that juggernaut, good info. Any thoughts?

Is the order in your list is a bit arse about - you've got the HTA3582 after the GT3582?

Yeah I wasn't comparing the HTA's to the GT3582 I was comparing like for like. If the HTA3586 was say 200rpm laggier than the HTA 3582 I might have considered it. But 500rpm is a bit more than I was expecting. The HTA3586 is GTX3582 territory both flowing 75lbs from memory - but i do realise from this thread that the HTA would be the better thing.

I keep coming back the the HTA3582 as the weapon of choice as I prefer response over outright horsepower (my other car is an S15 with twin scroll 3076 52 trim)

Will pick a Barra tuner here in Perth.......thinking either Monsta Torque or Extreme Ford Tuning and get their opinions.

Oh yeah, I expect that the HTA3582 would have a pretty big flow advantage over the stock FG turbo... Or even an edge over the normal 3582

The stock FG turbo is no slouch in the real world with bolts on's - approx 11 seconds neat with ZF - according to the Nizpro website - which ain't bad for a heavy family car.

The HTA3582 can only be better though!!

The list was in no particular order, the comments are where the data is.

Id be definately goin the 3586hta on a falcon 4litre, with motor that size i dont think ud notice the spool much. U gota remember when FP say 500 rpm difference most of their turbos go on 2litre evos, id guess ud be very gard to notice when actually driving the car on a 4litre.

Also the hta3586 is more responsive than a gtx, there is a guy who had a similar setup to mine, we both had gt35r and i switched to hta3586 and gained 200rpm im spool, he switched to gtx35 and lost around 300rpm spool. Both were without any other changes.

Haha, if u can get the thing off the manifold u can, id say its near impossible with out an oxy torch. Lol.

I nearly went the gt35/to4z hiflow before i decided on the hta, aparantly a fair bit of extra lag

Is what put me off, is that the case with steves?

Btw, how does steve get away with running in the 10s without andra approved car? Or has he had it passed? They were straight onto me last meet

apparently..f**k me, a 3540 is faster with a manual...as it makes way better"average" power, comp wheels to big!

auto with converter, yep would be faster..think the 67 wheel only make another 30 rwkw more ...way up top

Don't think Steve does get away with it..last meet he did one 10.5 and then put it straight on trailer, before they asked him

He at least has a 1/2 cage with front door bars..so they are going to be more lenient maybe, you have nothing though

cheers

Yea r32 gts4. Unfortunately at adelaide you cant run under 11sec without a cage so only get one shot at it.

I did do a 1.67 60' on my first run but got off it at half track coz i thought it wasnt a very good launch. Have done 1.58 at another track before but was only 1/8 mile.

Just so you know..the adelaide four/rotary turbo nats in 11 weeks, has got special insurance

Just like heathcote you can go as fast as you want with no cage, meaning for this one meet you could go as hard as you can

be your chance to do your best!, it won't happen again

cheers

Finally found a result for an HTA3794 on an engine a bit closer to the RB world in displacement and behaviour - someone did a "budget" high power build with an Audi A6 using one on pump gas, following mods:

Stock 2.7 with more than 100k miles only upgraded with IE rods (stock piston)
Running stock 2.8 heads (no 2.7 hardware) they were OEM factory rebuilt units.
Rs4 intake with 75mm BBk throttle body
Custom Single turbo HTA3794
034 IIc standalone Tuned by Dynodoc
Aem water Meth

Spool actually looks not really any worse than a T04Z from what I can tell, and these turbos are known to be able to make much more power than this on E85 - can clearly tell that it's not struggling with flow looking at the dyno plot, too. A built RB30, E85 and hearty boost and I reckon one of these things would be almost scary :)

Stands up like i was hoping it would, now to find someone to be a a guinea pig..lol

If you know anyone who might be that way inclined, let them know about this:

Super94 HTA: http://store.forcedperformance.net/merchant2/merchant.mvc?Screen=PROD&Store_Code=FP&Product_Code=NTFPSUPER94&Category_Code=Turbo-FP

Super99 HTA: http://store.forcedperformance.net/merchant2/merchant.mvc?Screen=PROD&Store_Code=FP&Product_Code=NTFPSUPER99&Category_Code=Turbo-FP

The T3 Super94 and Super99 HTA turbos are currently at US$1725 which is getting near standard Garrett GT turbo price, they are doing a clearance (and also looking like they are digging the boot into Precision as they said let on EvoM to them know if you are looking at getting a PT BB and they'll price accordingly...) as the new generation HTZ turbos will be coming soon.

Thats a good deal.

Darren, u should twist steves arm to get one, probly still more responsive than his hiflow thing and tell him he will bewt corran and run in the 9s.

i bet the .82 3794 would be closeish enough response wise to the 1.06 67/3540..and a massive increase up top...

I am trying,

but even a 3586 put in his 1.06 internal gate housing would work ...

ive been twisting for months..lol, its hard work

but because he can't.... or doesn't want to work on cars like us, hes up for all the labour aswell, so its a expensive exercise for him, for us it would be fark all

its a pity, as with a rebearing and rering, one of those turbos and use the nitrous he has on it..it would kick ass..

cheers

    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
