Hey guys,

Been looking at these turbos for quite some time and have been very impressed as most people are, I have a r32 with a built 26 with a gt3582 6boost and all the rest making 460rwhp, I spun a bearing now building a 26/30 and have my eyes on a super 94, my power goals are for over 500rwkw which I now the turbo is capable of, ive ordered a new 6boost mani twin scroll t4 and was thinking of going the 1.15 exhaust housing, I have a fair bit of head work done with big cans and gears, just wanted to put it past you guys before I lay the cash out.

Hi - sounds like you are on a mission for something pretty intense :D

The Super94 HTA is an awesome turbo, and as much as I'd love to see one on an RB - it's more turbo than you NEED to surpass 500kw, over 500kw is a broad term so if you mean anything over 500kw but with maximum response then the Super94 is more turbo than you need for the job.... being that its more a 600kw+ turbo when ethanol gets involved.

In saying that, I have been talking to someone with a Super99 HTZ on his 3litre Supra road car and he reckoned even that wasn't actually that hard to get to come alive once he was over 4000rpm and the Super94 is a reasonable amount smaller on the compressor. The short of it is I don't know exactly how responsive the turbo would be on a 3litre, I don't know of anyone who has used one and got it fully tuned on a 3litre yet but have absolutely no doubt at all it will go over 500kw with supporting mods to suit - I'm just not 100% sure what response you should expect compared to other turbos which will also get you in the 500kw range on E85, absolutely not saying it will be a laggy sack... just you will have one of the most responsive turbos you can get for it's target power range, let alone for the money - but if that power range is higher than yours then you may be sacrificing a bit of response.

Interestingly enough I actually had this conversation with someone a few days ago and am still soul searching whether I want to go the exact same combination on my own Skyline or not - and if I decide to build an RB30 it's one of the most likely options I'd go for. I've been in Skylines with comparatively sized (physically) turbos and motors and found them perfectly liveable for my tastes... and even if I weren't to use the full flow, I know I have something usable that isn't straining to make 500+kw and has the option of going full retard on occasion if I want to run a hero boost level. It just depends on your taste etc.

edit: You posted while I was writing my speel. AWESOME! I am really really keen to see how this goes :D I hope it turns out well, it's certainly got the potential to be a monster. Is it a GTR? Hopefully you have a strong motor, gearbox and big fuel system :D Damn that's shit timing with the pricing, they were still cheaper yesterday... I am sure.

Haha yeah should be alright, I checked yesterday they were $1875 then this morning when I woke up they were $1999 so I bought one now they are $2299, the car was a gts4 but now rwd, its going to be on e85, 5ltr surge with twin 044, 2000cc injectors, hks rail turbosmart reg, bottom end built by lewis engines and gavin wood putting it all together, still got other bits and pieces coming but yeah I agree in going the 600rwkw mark sounds more realistic

Running a gtr box still, I know its not suited but a ppg gearset is on the list or if I find another gearbox before the engine is finished, im not too worried about that now just sorting the engine out

Got my HTA3076r the other day from a member on here.

Cant wait to get it on.. will be a month or so from it yet. but will post a spec sheet and results soon

Awesome, look forward to hearing how this goes - keep us updated :)

Was a built 26 running 18psi on bp98. It was pretty loose driving it then should be good fun with this new combo

It's going to be mental, would make for an awesome overlay for comparisons sake if that's possible! When are you aiming to have it going?

Ive just been ripped off on a rb30 shortblock so not too sure on when it will be going now. Fp told me it will take a few weeks to build the turbo so it should be ready to ship next week. I will be using different dynos and tuners.

  • 2 weeks later...

I definitely have ear to ground on results, and also all ready to give people bad ideas if the opportunity arises haha :) I would have succeeded in one case, but the person needs a T4 housing... argh

  • Like 1

my mate is after this type of setup atm, but due to no results atm, has gone for a Precision 6466 T3 .82 on a rb30 sohc low mounted./gate on stock manifold.

cheers

darren

Please share the result once done. I am throwing around ideas for a low budget race car.

    • Not a problem at all Lithium, I appreciate your help regardless. I've pulled a small part of a log where the target pressure was 28psi and it spiked to 36.4psi. I've only just begun using Data Log Viewer so if I'm sending this in the wrong format let me know.
    • Sorry had a bit of a week and haven't had heaps of time to follow this, so apologies if I've missed something - any chance of showing a log with the rpm, turbo speed, MAP, and wgdc all in one view? Definitely an "interesting" problem, and while it's definitely worth noting that there was a similar issue with the twins I'd not completely put all bets on the root cause being the same thing.  Keep an open mind, follow the data.
    • I built this engine approximately 12 years ago so my own head (brain) is a little grey on the exact hardware in the RB head, however what I recall is. Stock RB25 NEO TURBO Intake Camshaft HKS 260 degree Exhaust Camshaft (R34 GTR) RB25 NEO Turbo Springs  I ported/removed the exhaust stud humps found in the RB25 head so theres less turbulence but it wasn't ported/polished properly, just a hump removal. I've attached two pictures of the before and after to illustrate.     The ECU gets its boost reference from the nipple on the rear of the head on the intake side, behind the fuel rail. The wastegate gets its boost reference from a nipple on the cooler pipe immediately after the comp cover.  Could a decent pressure drop across the intercooler cause the wastegate to be seeing a higher PSI than what the ECU is seeing, and thus it can't control it accurately and quick enough?   We ran a line to the actuator and watched it open and close using an air compressor, while we didn't have a gauge on the line to see when it was cracking open, it was opening smoothly.  I just removed the gate now and even though the documentation says you need to open it in a vice due to preload (which I did), there wasn't any preload on the cap, which is something we noticed straight out of the box as well when new. This silver cap internally is threaded to the actuator rod that runs out the bottom of the straightgate. Not sure how I'm supposed to get this spring out to be frank.. Potentially but everyone else doesn't appear to have to stop at 500kw because of 6boosts design.  I would, but I think I'm getting to that point where if I'm going to do the head and make another 100kw, then I'm going to need a fancy gearbox and quite a few other things and 10k becomes 20k becomes 30k within a few months. I'm not necessarily sold on the idea just yet that the head is restrictive at 4000rpm (and what.. 300kw?) and yet doesn't seem to be restrictive at 7000rpm when it's making 500kw, however I'm obviously not closing the door on that theory.
    • Yeah - Half the problem is I know this sensor actually goes to 150C.. I'm pretty certain it is min of 11C. So still more data required I suppose. It's really quite hard to get the oil temp to 100+ then immediately pull over and take a reading before the temp drops. Annoyingly I suppose the range I really 'want' is likely 80 -> 120C. TBH the ecu can't really *do* anything with it, and the gauge itself is very visible... ...but you know how it is.
    • My EFR 8474 Black, made 800awhp on a roller dyno. at 25-26psi. E85. Shaft speed was around 106,000rpm 1.01 rear. The rear is maxed.  6 boost Turbosmart 60mm gate 3.5inch exhaust  Head is worked to the shithouse. Bain racing. VCam. 272 exhaust. RB28 - RB26 foundation.  You have an intake issue. Start getting proper data and I mean go back to the simple things.  - Pressure test your intake - Block off the Turbo BOV, you don't need it.  - Test pressure before and after your intercooler If your head is pretty stock, that is your issue. Especially if it is NA.  Take it off and spend $10k on it.
