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 ;)

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

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!

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

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.

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? :D

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

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.

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!

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.

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 :O

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

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! :woot:

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 :D

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.

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...

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

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.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
