Built 26, Best Single/mani Combo For Around 370Kws ?

The ECU was in the car when I bought it, could've been to the bottom of the ocean for all I know...

Fingers crossed mate! Hasnt been the smoothest start BUT at least you know you have killer performance to look forward too! A nice eye opener for some

Oh dammit, I had assumed it was a mostly fresh build. Back to my initial sentiment, I hope it isn't a major - this is probably my favourite GTS25t build I've caught wind of and is going to be a potent race car when it's sorted, so close!

[bri73y]

Thanks Lith, it's my favourite GTST build too!

Gotta say, I actually prefer the look of it to my 32 when side by side in my shed. It's really starting to appeal to me.

I think my son my have his hands full getting it off me once done!

I actually drove it last weekend at SMSP South in a club day. Still on run in tune and oldish tyres. Enjoyed it, handled well, made it through the whole day without any issues, all good!

Managed a 1:03 which given the power, tyres and the fact I'd never driven the South Circuit before was not too shabby. Reckon it'll be fairly quick once finished.

Thanks again for your help.

[34GeeTeeTee]

That is awesome! So the run in tune was still the 390hp or whatever it was? I assume it feels fairly responsive as per the dyno print out?

I really want to try the South circuit, looks like fun!

[bri73y]

VCT was off, another part of the glitch. Not really responsive to be honest, needs more powah!!!

I wasn't revving it particularly hard though, nothing over 6000rpm, that wouldn't have helped.

I hated the South Circuit after the first run but kind of warmed to it's little challenges throughout the day. Would go back.

[34GeeTeeTee]

Ah OK, well at least you know good things are soon to come! Oh and you KNOW more powah is there too

[Lithium]

A bit surprised it doesn't seem that responsive, though 6000rpm and no VCT will be keeping it from sharing its best - as you indicate. Hopefully with more rpm, more boost, and it's proper cam timing in effect it will become a different beast

And awesome to hear it has had a bit of an outing, well promising!

[bri73y]

Well I now know why it felt sluggish last week. It had a hole in the silicon joiner off the turbo. Was only making 225kw.

I drove it again last week on 16psi/280kw and managed a few 1:44s around EC full circuit. Looking forward to a high boost run when it stops blowing up silicon. Managed to destroy 3 hoses in 3 sessions.

[Lithium]

That's frustrating, but good to know its not an indicator of the turbo's performance. How was it's response without the leaks? Granted at 280kw it still won't be showing its full magic - but its got to have been a bit better!

Thanks for the updates, looking forward to hearing how it goes with the wick wound up a bit - those sound like really sharp times already! What times does the GTR do there?

That would explain a few things... I'll keep the silicon joiner thing in mind now

That is a damn quick time for EC mate! Wow!

[discoPumpkin]

what about the T04z?

They make that power and then some all day, infact it's what Denzo has on his drift s15/RB30 so its good for response

It's an RB30..... Different story!

The numbers and response this turbo is producing will be impressive... If not the HTA3582 would still be considered responsive and make more power again...

If you see the times already done as per the post about you will realise this is one fast and well setup car! That sort of time on low power is a good indication of things to come!

Guys,

About to build another track car and want to go down a different route to my current R32.

This one will be a rear wheel drive GTT

I'm looking for a single turbo/manifold combo that will net around 370kws.

Motor will be kept pretty simple with a built bottom end, drop in poncams, very little headwork, running on E85.

Looking for 20psi by say 4000rpm.

Give me your thoughts please.

If I were building exactly the same thing, going by the things I've seen out and about these days - I'd go for a single entry FP GT3076R HTA with .82a/r hot side on a 6boost manifold.

I'd say your 370kw on E85, and 20psi by 4000rpm should be pretty achieveable with that combination - potentially with change.

I'd like to take this opportunity to say BOOM! headshot. Can confirm the above setup is capable of 20psi by 3700rpm and 391rwkw, so plenty of change - courtesy of R34GeeTeeTee doing everything mentioned bar the built bottom end, and E70 instead of E85. I like being right, especially when I would look like a right douche if I wasn't

See the attached dyno plot - has his 360kw GT3076R result to compare with the new HTA result, the old faithful GT3076R has no answer for the HTA anywhere.

[discoPumpkin]

thats awesome!

148000kms = original?

[34GeeTeeTee]

thats awesome!

148000kms = original?

100% original including the headgasket mate! Car ran 200kw for a while up too 115000km, 250kw up to 150000km and then 360kw to where it is now... The 391kw starts at 148000km with its first actual drive tomorrow...

During the turbo swap we kept this quiet and say back to see what people had to say, it is now proven twice that these turbos are more than capable and as Lith said the old GT3037 had nothing on the new HTA76... That 3037 was maxed 100% too...

It certainly was a good call lithium, wish id of gone TS HTA now, but im still happy,

looking at the printout, the HTA is running more boost than the GT3076 so is this because the GT3076 is out of efficiency and cant run that same boost?

We tried more boost in the 3037 bit it had nothing left to give...

[discoPumpkin]

how would the HTA 3076 compare to the HTA GT3582R that lithium was advising in another thread

[Lithium]

If I were to extrapolate from what I have seen elsewhere I would say prepare to see around around 400rpm more lag and maybe up around 460-470rwkw on E85 with the right setup and the end result shouldn't be too surprising.
