You answer your own question the h has a bigger turbine wheel I had the td06h-20g on my 20 and was seeing full boost at 4200 18psi so it's only a few rpm if you want bigger numbers

Not really. Ill word it better this time lol.

In terms of 350KW going the 12CM housings on the TD06SH 25G and the T67 25G both can do it but would the TD06SH bigger wheel (more lag) would it be worth it for the extra power it make. As if it makes say 15more HP with much more lag then it wouldnt be worth it?

But i cant find much info comparing the 2 or in 12cm housings, so im just asking opinions.

My 30DET is now running TDO6H 25G, budget build with Hybrid manifold and 50mm Turbosmart gate. Turbine is the 11 blade option with 12cm housing. Tighe camshafts correctly dialled. Track car, chasin

And r33_racer or whatever also had around that figure too? Maybe it was 380? (struggling to recall)

If you were looking for a easy 350KW on 98 would it be better to go as TD06SH 25G 12cm or T67 25G 12cm?

Is that a fair statement? An easy 350rwkws on 98? I suspect it would take 20-22psi on a well tuned RB25 to make that power....I still go by Dyno Dynamics numbers...I dont know if that makes a difference but I think you can say the T67 and TD06H-25G will both make an easy 310rwkws at 16-17psi. The "H" version may make in the vicinity of up to 10-15rwks more?

I am not sure that going to a bigger exhaust housing will also give you significantly more power as the 10cm doesnt appear to be a restriction. Agree that if you went from a restrictive housing to a more free flowing housing you would bet results.

I suppose I am a bit of a scratched record but think we should all be careful about throwing numbers around, especially numbers that may be a little high

The td06 is a good turbo fairly responsive yet gives good top end the td06h-25g is bigger then the t67

Well I noticed one of the guys is making 400+ kw off his t67 and my aim is around 300-350. So maybe I need to look at the 20G instead of the 25G?

Simon's car is an animal and makes whatever power it does...its a big number because the thing runs 11 flat on the quarter and blitzes around race tracks. He has various dyno sheets from various shops where the car has been run. He runs a 50:50 E85 mix, so that helps with power, but still not a full E85 tune (is there much difference in outright power? I got no idea...but I know its helping his power over std 98)

I think it was a dynapak that put it at 410rwkws. A dyno dynamics put it at 480rwhp (or 360rwkws)...so as BSA GTScoT and others have been saying...do your own research and look at other sources rather then just SAU. If you want 350rwkws from an RB25 I think you need to push a 25G based turbo.

the way I see it, the last thing the h wheel will do is add power anywhere in the band. What it will do is add a little more scope to the compressors maximum flow.

Simon has already noted that his compressor has maxed out before the hotside, what more do you need?

that being said its no science to see the h wheel will be application specific. For example if i wanted blitzing 350kw and i put a t67 on a bad ass rb34 but the thing maxed out at 5500rpm, i would know the restriction was in the hotside. I would then try move to a larger housing, and if that did not yield the result inwas after I would then move to a h optioned unit.

Obviously the idea is bring the thing on later and keep it on longer. It would be trial and error between 10cm H or 12cm L2 in my eyes.

And again Simon is reving his to 8 with no sign of turbine cap. Now lets all forget about the h turbine until someone builds that bad ass rb34 i mentioned.

Roy is pretty much spot on here... 410kw at the hubs on a happy hub dynapak 360rwkw on a dyno dynamics roller.

My mix has a huge advantage over a 98 tune. It probably would not make any extra power with E85 as we can wind as much timing as we want in without detonation as it is

I think it may be maxed out, don't know that for sure... May be another issue, either way I don't really need any more power

In saying that, I may be going from Nistune to Vipec and dropping some cams in soon... Someone stop me FFS

24-25psi and that would the least amount in that turbo sizing..

Why the change from Nistune to Vipec? I Interested to know what cams you are looking at as well. I would be tempted to stick with the std inelt cam and go baby 256 exhaust cam

Remove the AFM from the equation... The Z32 is out of its depth already and makes the cooler piping a lot better!

Cams would most likely be a set of poncams.

      WGNC34 - floor mats

      By soviet_merlin · Posted

      I'd be very surprised if you can buy new OEM mats. But if you can, I want some too!  Do you have links to the variations you found? Also, where are you located? I found that Nengun is happy to list items to purchase but when you do buy them you'll get an email that it's actually discontinued. As far as I know the variations in floor mats are different colour schemes as well as automatic and manual having a slightly different shape. The automatic ones fit into a manual car without issues, but I think you'd have trouble fitting the other way around. I have photos that show the shape difference if you care. FWIW I bought sets of used floor mats in decent condition at yahoo auctions.

      WGNC34 - floor mats

      By Marek · Posted

      Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏

      Hi, Marek here 🙋‍♂️. I finally fulfilled my longtime dream - recently bought Stagea and now waiting for it to arrive in Poland. There's only few of these in my country, and one of the owners  recommended mi this forum as a source of all the info i'd need since now i own one  so here i am.

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.
