Any more progress with this setup? :D

nope... havent even driven the car im in thailand atm :D and ill most likely return to australia broke as a joke to be able to do any thing to the car

ive also got to focus most of my money on my 180

Edited by STR8E180
are the oil pump gears a replacement for the standard pump ?

how actually makes them ?

yep they are a replacement for the standard pump

they wont fit the early model R32 RB26 crank shafts, this is the reason why im using a R33 RB26 crank shaft

how actually makes them ?<----- u mean who actually makes them?? its a CNC machine shop in sydney but its heated treated by another mob also in sydney

Fcuk man, surely everyone is getting sick of the twins V's single debate.

Anywhoo, im really interested in the oil pump you have. Any chance of PMing me with some contact details and a price?

Thanks mate,

Shaun

PS; Single all the way.

I thought I'd read through this whole thread , backwards as it turns out , to see the original spec sheet .

I'm reasonably sure that the "T3" flanged twin entry turbine housing is a modified GT32 casting which you can see at the turbobygarrett site under GT32 .

Geoff Raicer (FR) has mucked around with a few TS housings on GT3582R's and that one sort of works (sort of) ok on the 35R but he thinks and I agree that it's a bit small for the compressors capacity . Don't quote me but I think I remember reading that he thought that GT32 0.78 A/R TS turbine housing became a bit flow challenged at figures approaching ~ 500 Hp .

Now it depends on your vews of the TS system but he thinks that when changing from single to twin entry turbine housings the best idea is to go up on A/R size to benefit from lower turbine inlet pressure for about the same or better turbine response .

The modified GT32 housing has been used on GT3071R's and GT3076R's with some success and this may be because the exhause flow capacity is more in step with those compressor wheels airflow capacity , 440-540+ Hp .

I've often wonderd how a set up like yours would go with a GT3076R substituted for the GT3582R but you don't tend to see 3076R's as singles on RB26's .

Back to the TS GT3582R , in the US some have fitted modified "T3" flanged TS T04 turbine housings though some think the ports through the "T3" sized flanges are not big enough for the sort of exhaust flow a 3582R can generate on a well set up engine .

Garrett were supposedly going to do a TS T3 flanged turbine housing in I think 1.06 A/R for these turbos this year but nothing on the shelves yet that I know of .

Best of luck with it , cheers A .

TS T3 GT3582 would definately choke. Thats why Geoff is currently developing T4 TS for the 3582 and 4088 turbos. Even the modified GT32 in TS .78 is marginal for a 3076 thats probably why they really make no more power than the 3071 in this format. If going to a 3076 TS I would use the .82 A/R TS housing.

The whole twin scroll thing is really about broadening your power band. It does this by pulling the torque and therefore power curve to the right because of the improved VE from reduced back pressure. You can then step up the ex A/R and this gives you back the top end as well.

I'm not up with what he's doing ATM but he did try the hard to get the "Tractor" TS turbine housing but it's a screwy T4 flanged casting with T3 sized inlets in it . I think it's ratio was 1.06 A/R but its based on a dinosaur T3 turbine (no kidding VL T3 type) so lots has to be machined out to get a 68mm GT35 turbine into it . I think he did test one but the ports were really too small for a 35R .

The one he used to like a while back was a Turbonetic thing called F1-35R . From the pics it looked like a large frame Garrett ? center section with no water cooling and whatever Turbonetic calls an F1 35 turbine .

I'm not sure if the ball bearing pack is Garrett or some Turbonetic ceramic (caged) bearing system .

Garrett is really letting us down by not developing TS turbine housings for the petrol spec BB GT30 and 35 based turbos .

Twin integral gates ones like IHI and Mitsubishi do would make life really easy for us but they must not think there is much of a market for them .

Cheers A .

The new T4 setups Geoff is currently developing have T4 TS inlets not T3 - i've seen the pics of the bare manifold and with the turbo's on the manifold.

In the case of the SR's this new range of manifolds also have dual gates for true twin scroll much like the rest of the Full-Race range (previously only single gate gate for the SR's). Looks like there will be a range of T4 based Borg Warner turbo's as well. Check out the Full-Race website.

im not looking at making 500hp which is why i went with this exhaust housing

i dont intend on doing any bottom end internal work apart from the oil pump and new bearings just to freshen up the bottom end just so its abit more of a reliable daily

im running a GT3076R with the same .78 divided exhaust housing on my 180SX SR20 but its got a P12 SR20V cylinder head conversion getting done as we speak

the exhaust manifold is also a twin scroll manifold but it doesnt run twin external gates it has outlet's coming from both side's of the collector merging together at the gate

CIMG0289.jpg

runners 1 and 4 are divided from 2 and 3

manifold is design with very close to even runner lengths while trying to keep the runners as short as we could

havent got results on this setup yet because its taking alot more time to finish then i once thought due to the amount of work going into the engine and fuel system but once ive got some results ill be posting them up

Where abouts on the website is the details? Just had a bit of a look and didnt see anything

Funny thing i did see was - you can run 700rwhp through a stock bottom end with a "conservative" tune... i think they be tripping personally :whistling:
