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.

    • No. GKTech arms have spherical bearings in them. No bushes. You will not need bushes for those arms. The sphericals are a bit of a maintenance nightmare. I have replaced all of mine several times in the 5 or so years I've had them, and I have the arms out regularly to clean and lube the balls. Worth the pain on an R32, because the standard arm design is trash. If you need the camber adjustment, there are other options (than the GKTech ones), although I would still lean towards and prefer the GKTech ones, even with the maintenance load of the sphericals. The caster adjustment is also highly valuable, allowing for setting the car up to drive straight. There are a million options for these, including the GKTech ones. I've had Tein rods on mine for 20 years and the balls are much less trouble in that location. Never given me a moment's pain. All positives, no negatives. I consider them compulsory.
    • Lol yeah I ordered the clips mentioned and as far as the amayama diagrams go i think thats all I'll need. Fogured id ask, sometimes people's first hand experience doesnt always match up to diagrams haha, i guess I'll wing it and worse comes to worse I'll just deal with it as I go
    • Thanks for all that information I appreciate it. To answer your questions: - Yep that's what I mean. These guys are professional painters to so I must be missing something. It's a bit hard to explain. - With the primer landing on clearcoat, I make sure that the surrounding clearcoat is scuffed to 240 grit as my epoxy primer says that I only need to sand the area to 240 grit. - Yeah so similar to the first question, assuming that the paint landed on the unscuffed clearcoat because I've seen that happen. - Yep I want to prep the surface in that order. Only reason because epoxy primer will protect it from rust and I need that atm with this crappy Sydney weather. I think I was worried about time, if I try to put the filler down but screw it up somehow and I don't have time to sand it off and reapply it then need to put primer later that it might start to rust again so I wanted to apply the primer as quick as possible to not deal with rust.  - I just deleted some answers, I just realised after watching a video and what you said about looking at the data sheet, that I need to read the data sheet on the specific filler I'm using. It's possible now that I put epoxy primer first was a waste of time and need to go to bare metal lol
    • I did. I went to a suspension guy and he told me because I don't have adjustable camber arms it's the reason why my car veers towards the left if I take my hands off the wheel but if I drive my other every day car and take my hands off the steering wheel it goes completely straight. I think it's common with Skyline's. In order to fix the problem, I likely need gktech camber arms then nismo bushes since I have poly bushes atm, then a wheel alignment after that. With my car if I take my hands off the steering wheel on a really bumpy road before stopping at a light I have to hold my steering wheel somewhat tight otherwise my car will legit just go completely in the other direction quite quickly and I'll slam into something lol instead of stopping straight. I Believe this YouTuber had the same issue and fixed it with gktech arms. At timestmap 6:05 he talks about how the car doesn't veer anymore after installing these arms.  
    • hello! does anyone have a schematic that shows how to test the blower motor resistor for the vac system? i believe the part# is 27761-15U00. I think the resistor is toast, but would like to be able to test it somehow before i embark on the journey to find a new one. cheers! 27761-15U00
