Whats the largest set of factory mounted.. or there abouts twin turbos for Gtr?

i was going to go single route and T/s but since i have everything to use twins i might just get the car back together and be done with it..

I got tomei dumps, amuse titanium front pipe, stock/ported manifolds hks hard pipe kit from turbo outlet to cooler.

some of it i guess may need to be modified to fit to the turbos but wont be a problem..

All to go on a fully built Rb26 with Tomei 11.2 270 degree cam's

i searched for an answer but my search contained too many words

It's between the T617Z and the Garrett dash10 with the large rear option

GTRS's are not the largest, the Garrett dash10's are 60hp more per turbo.

I can't think of the figures on the T617Z, but yeah the dash10's are larger than GTRS: GTRS pair is 800hp, Dash10 pair is 920hp :banana:

If in the future I need/want a larger lowmount, dash10's will be the choice but if an oversize front fan could be fitted that would be ace

Ahh shit i didnt realise -10's were 920hp

looks like thats the path i will look down then. since its probably the cheaper option out of all of them..

i was thinking something not from the gt28 range

I would give the t618z 10cm2 a go. they would give some mighty big top end with a good engine, your big cams and don't forget to run them at 25psi+. :banana:

Its between the -10's and trust.. but i can get the garrett alot cheaper.. and already have the gaskets and braided lines for them....

i would love to do twin highmount but my sexy titan front pipe wont get used.

I have a 3.* litre full counter stroker in the pipeline...ill look into using the large rear housing -10's. Ill let you know how they go.

i was only thikning of this the other day, good time for the post to be revived. Does anyone have any real world results using the larger AR rear housing garret -10's on rb26, stroker or rb26/30?

Are the larger housing options known to shuffle like their gtrs equivelants?

Edited by blue_vl_t

When I built my rb2630 with -10's at the time, I was strongly advised to stay with the smaller rear housing (.64) so I did...the larger rear which was .82 from memory and was not recommended due to the fact that the larger rear is designed for single applications and if the larger rears were run as twins would require a 4.0ltr minimum.

To put into perspective, my mate bought my long engine for his circuit car and the .64's were still too laggy for his application, although, on the street it had PLENTY from about 3500rpm :)

i went for a drive in a 400+kw r34 gtr with a hks 2.8ltr and gtrs (big track car build from japan, big brakes ect ) on it and i absolutly couldnt wait to get in it, id been in and driven a few cars including a track prepped 2.6ltr with 2530s but never such a wild build like this, altough the r34 pulled like a train once past around 5000rpm, in all honesty it wasnt really exciting at all, nowhere near as exciting as the track r33 with 360kw, i mean the r34 had to back off at about 180( on a private road of course) as he was running out of road but i guess it all depends on what your after, im sure on the track this 34 may have been a different story all together, but i personaly think that the gtrs turbos he was running were way to big for his application(2.8ltr and street car), let alone a 2.6ltr, i mean im not sure what your after but by the time the power is unleashed its going twice the speed limit,

im sure there would be proven setups on the gtrs on 2.6s out there, but im just goin by my own experiences ,

but if its a drag car or set up for big tracks then by all means, i cant remember if twoogle was a 2.6 or stroked, but that pulled a 9 so depends on your application i guess

    • 2 does "sort of" applies, maybe......but looking at what parts would be needed for the swap to get engineered, registered, and insured, and basically that's everything under the car, the modifications the make it legal would be problematic and horrendously expensive, all for a street car that just cruises around and hits a few twisty roads on the weekends Also, from looking at the NSW rules and Regs, with all modifications that is required just to make the car safe and not twist itself to pieces, and then actually get registered for street use, may still be impossible nowadays As for 1, when you add in a fresh engine, fresh transmission, rear cradle and diff, tailshaft, suspension, brakes, cooling, and all the other fabrication required, your probably looking at up to $100k to do it right, all for a 20 year old MX5 that is over engineered and you would never be able to actually use the power it has on the street, much like your beastie, which I love, but you actually track that thing and can use all of its powers in anger, in a safe environment  Hell, the old Bogan Cruise Ship had more power than I could use on the street, and in hindsight, I went a bit silly on that thing, it didn't really need the 500hp it had for what I actually used the car for, it was fun, but basically unusable on the street if you value your licence  As for cams, yeah, I'll probably book it in for them to get installed and tuned soonish, like next month after MX5 Mania are back at work....... and yes, I've already sent a email to bin the turbo quote and quote instead to install cams and a new Fluidampr balancer that will suit the 2.5 better than the OEM 2.0 balancer that is swapped over for the 2.5 install, as the balancer needs to get pulled to time the cams it's a while your in there sort of thing I did think a bit about flex fuel for a laugh, but being na, and no where really around locally anymore to get E85, I've binned that idea, so no sweet sweet corn smells are set for the car I wish E85 was more of a standard fuel, it's better for the environment, better for tuning, plus that sweet sweet smell we all love As for fitting in the family, that's not needed, as everyone in the family already owns a car that can seat 5 humans comfortably enough, the MX5 is "my toy" As for buying a car that is already built, nah, I would rather pick and choose my parts, I enjoy the process, and in the big picture, the additional cost is well worth the enjoyment, and the occasional frustration, I get out of doing it, albeit with other people spinning the spanners, and me, just paying the invoice 🤣
    • Excuse me, but 2) does apply 1) Would also apply if you consider how much is spent in the alternatives. Also there's the option of 3), buy one pre-built that you can put your family in (it's me, it's my car)   That said, I went on a ~500km drive the other day. I didn't use anything more adventurous than 3rd/4th gear at about ~3000RPM and 50% throttle and I was going as fast as anyone has any sense doing on a public road, with enough grip to the point where I didn't want to go any faster. I was obviously under the limit of the current car etc etc. MX5 with 2.5 N/A to achieve the same speed would be more fun for any road scenario. Maybe consider cams. I wouldn't boost it. The use case is just not there and it won't actually make the car more enjoyable unless you really do plan on wringing gears from 1st to 3rd (at least) at 100% WOT on a public road to 150+kmh.
    • Great if: 1. You had all of the money for everything else that is required  2. Lived in a country where you could actually do this and drive it legally on the road Sadly, neither applies to me As for the turbo, I am having second thoughts, mainly for engineering/registration legality reasons and insurance  Not saying I've finished doing stupid things that I probably should do to the MX5, but boost, and V8 engine swaps isn't on the cards Strange, but true
