He must have also run one on an SR......it was a 3071 .63 with external gate and Unigroup cams. Posts 83 & 85 (where Dave chimes in). http://www.nissansilvia.com/forums/index.php?showtopic=413229&st=60

Not directly on point but it is my understanding this is a GT35 .78 TS hsg on an RB26. If it's legit I'm personally surprised the .78 TS hsg was capable of that power. http://img.photobucket.com/albums/v482/str8e180/dyno2.jpg

Here's a dyno of a GT3071 with a .63 hsg on an SR with small Unigroup cams (pretty sure it is BHdaves setup). Full boost arrives at 3,600rpm and made 285rwkw. It would seem that the GT3071 would have fitted your requirements. Nevertheless, I would change the rear hsg on your setup to a .63 for a better match to the compressor and desired use of your car. Perhaps a different tuner may also be able to fully exploit the potential of your setup.

I faced the same issue with the SR version of the full-race twin scroll manifold too back in 2008/09. I had a 6061 10mm ali plate made up which bolted onto the block at the original location and then had the plate heli-coiled about 25mm lower down (from memory) to accept the compressor bracket. Obviously you will need to adjust the positioning of the bracket to suite your compressor line clearance. I also put heat sleeve over the aircon lines too. Six years later and no issues......well except for loss of licence

Perth dyno's always read lower Yep just throw more boost into it once the control issue is sorted.....as it one thing the GTX's seem to thrive on. Please post up pics.

Nismo close ratio 6 speed box. Standard diff gearing. This dyno run (run no. 42) was done in 5th (1:1) - despite the dyno printout showing 4th.

@ Mark - here was my previous GT3071 setup revved to 8,000rpm so 4,000rpm would be around 112klms

Your confused with stock-ish

Great result for a mild setup.

All good

Judging by the thread responses this thread is about a 3067 vs other Garrett variants. I'm only offering my experiences so people can make an informed decision about turbo choice.

For reference purposes - boost graph of a 52T 3076 on an SR with twin scroll .78 hsg. Note that 150kpa is a tad over 21psi - which as you can see is made at around 3750rpm and positive pressure at approx 2300rpm with big Hypertune short runner plenum. At the end of the tune it went on to make 389hhp on BP98 with 240hhp at 4000rpm. Very torquey (for an SR20) and revvy setup. I changed over from a GT3071 on the same setup but with larger dump 3.5 inch up from 3 inch and the 52T 3076 is superior in every way. I expect it would work equally as well (if not better) on an RB with .5 litre larger capacity in a single scroll format with standard intake manifolding.

Its not the welds - but rather the pipe to flange fitment i found the 6Boost to be better. I spent some time with a die grinder blending on the full-race. No such "tidy-up" was required on the 6Boost. Interesting observation....the 6Boost also runs a shallower angle merge collector compared to the full-race and the above billet collector. Better.....who knows? The full-race runs cast stainless pipe whereas the 6Boost does not. Perhaps the cast stainless is heavier. On the jig On the car

I've had both 6Boost and full-race (as mentioned above) in the sr20 configuration. The pipe diameters were the same and quality were both excellent but would sway towards the 6Boost for a better quality finish (this is back in 2008). The full-race is a heavy bugger being cast stainless and comes with lifetime warranty to the original purchaser....as I think the 6Boost does too.

I've had a full-race twin scroll dual gate sr20 manifold since 2008 (probably one of the first in Australia to try this full-race setup) - no issues and great quality. http://www.skylinesaustralia.com/forums/topic/249832-my-sr20-build-pics-inside/?hl=+twin%20+scroll%20+sr20%20+build%20+thread http://www.skylinesaustralia.com/forums/topic/260427-my-sr20-build-twin-scroll-3071/?hl=%2Btwin+%2Bscroll+%2Bsr20+%2Bbuild+%2Bthread#entry4501892 I've had more problems with the Hypertune Intake manifold.

You can opt to have them built with metal cages though.

3 months - strewth!!

Whats the current wait time on the FP turbos?

Thanks - I was specifically looking at the HTA3582 or HTA3586. Given that Forced Performance offer their comp housings up to the 3794 (90 lb turbo) I'm guessing they'd cope on either of the above turbos without issue.

Apologies if this has been covered in the previous pages (I've read most but not all) - but has anyone ordered a HTA turbo and optioned the proprietary Forced Performance 3.25in in / 2.00in out anti-surge compressor covers. I only ask if there are any real world downsides to the performance of these covers which may fitment advantages over the physically larger 4in in / 2.5 in out covers. Cheers in advance.

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. 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!!

Yep if i were to go the metal cage route I would deal direct with FP so there is nothing lost in "translation". I just though that link up there for others who might be interested in a local dealer. In responding to my email questions - FP also advised that, although heavily dependent on the setup, their 3586 is about 500rpm laggier than the their 3582. Further, the turbo's can also be bought without the ex housings and are $175 cheaper without the housing (in the case of the 3582 and 3586 anyway).

Email confirmation received that the FP turbo's are built with the GT bearings but can be built with metal cages if desired. In other news I noticed that Alpha Omega are dealers in Forced Performance turbos - scroll approx 3/4 down the attached link. http://www.ao-ps.com/fullrace.php

Correction...the F6 turbo was pushed to 442 on 98 with 21-22 psi....with just over 400 daily at 17 psi ...post 102 http://www.fordxr6turbo.com/forum/topic/79417-post-your-max-3540-3582r-and-gtx3583r-power-figures/page-3

430rwkw on the GTX3576 is E85. Think the F6 Turbo made 450rwks on E85 from memory. All other numbers pump. Yep HTA 3582 and HTA 3586, depending on your preferences, would suit the Ford turbo crowd.
