The EFR 8374 took a few minor mods to fit... But sits well! Gate pipes, dump pipe etc were all completed over the weekend and are off getting coated. This was from one of the test fits on Saturday! Looks like heaps of space but once everything started to go together with both gates etc its quite tight.

HTA made a peak power of 524whp or 391kw @ 28psi On track we have been running between 15 & 22psi so more like 400-450hp to keep everything safe. The engine is the factory engine and has last 10 years in my ownership so far, it is beginning to get tired and i will have another fresh NEO lined up to go in soon! Hoping to run the 8374 and a nice sedate 500-550hp on track if all goes well!

Old setup removed from the car... New setup well underway! Quick video from last night -

Well i should have the new EFR turbo test fitted on the new manifold tomorrow, we can then fab the new dump and position the twin gates etc... Will get some pics and video of the setup coming together... Hopefully the parts will get coated quickly and we can have the car running in a week or two ready to go to Jez to tune... RB25NEO internally stock engine with EFR8374 1.05ewg... Dedicated circuit car so should be an interesting swap from the HTA3076 that has served me well for years... Here is a fab vid from last night -

Hi Mate, Geoff was very quick to respond when i was enquiring. He said to contact this guy for pricing - Jon Guerra in our front office <[email protected]>

1.05 TS yes... Twin 40mm turbosmart gates... Its not setup yet... Whatever Jez says goes in terms of setup

Well ill let you know if i like being in this thread in a few weeks The HTA was an epic turbo for the past 4 years as an all rounder but its time to step it up a notch... The 8374 should do that

I researched as much as i could and the EFR seems like a good solution for a dedicated track car... The current setup was creating a lot of heat and was somewhat restrictive.I looked at changing to a V band rear housing and redoing the dump pipe etc but figured if i was going that far i might as well make everything fresh. The turbo failure came at a good/bad time, bad because it failed and stuffed my day at the track BUT good so it didn't make me look like an ass if i sold it to someone used and it failed first time out for them... Its all shiny new now! Gen 2 GTX look great... But being new i don't know anyone that has pushed them on track for extended periods, EFR on the other hand i know have... I'm not saying this will be the right choice, i wont know until we run it... But so far it looks like a good one

Correct and correct! Last run for the mighty HTA yesterday and it did not disappoint! Going to miss it to be honest... Someone has a LOT of fun ahead of them...

Yeah mate, back to Jez in the next few weeks once its all back together! Plan to be back on the track for Round 4 in 4 weeks Be interesting to see how it performs!

Probably just because mine was already in stock? Who knows... But yes, you have the answer lol! Updates will follow over the next week or two...

What turbo was it? I nearly took up the sparesbox offer on mine but ended up getting the same pricing through my fabricator... I can check with him if you like?

Remind me not to stand near you in the dark anytime soon

Mine have been in for 6-7 years with the car doing around 15-20 track days a year on top of many KMs of street driving before it was made into a dedicated track car. Never missed a beat with the Performance Valve Springs! Good gear

Cheers mate! Whoever buys it will have a LOT of fun... Its fast and responsive enough to get yourself into trouble So am I Nope, i like women too much! 2 of the big ones

Hard to criticize someone for getting in and having a good go! I wish i had the patience and knowledge to mess with some of the DIY aero and body stuff, keep it up!

So the famous HTA turbo that caused quite a stir back in 2013 is finally up for sale, the original thread will all performance info and comparisons can be found here - This turbo has just had a full overhaul and is now like brand new... I don't think these turbos are available anymore but if they were they are around the $2.5k-3k mark by the time you ship them in and pay the taxes etc... And as far as i was concerned when i first did the exercise they were worth every cent of it. The GTX just had nothing for this turbo in terms of response and all round drivability on the RB25 setup. I am selling my whole combo as a package deal. It will save the buyer thousands in additional costs as it is basically a bolt on and thrash setup. The rebuild was quoted at $880 through GCG Turbochargers for new bearings and seals. It will include - Forced Performance HTA3076r with 0.82 rear housing. *As new - just rebuilt* 6Boost T3 single scroll high mount manifold Tial 44mm MV-R External gate with 1 bar springs fitted Speedflow fittings in turbo and braided oil and water lines setup for RB. Custom intake pipe with silicon joiners and 4 inch pod filter GFB Response BOV which has full plumb back option and is plumbed into intake pipe (Legal for street use) Alloy elbow welded to front turbo housing with cooler piper and silicon joiners supplied. Custom 3" dump pipe with plumb back or screamer capability, additional pipe supplied for either. 3" decat pipe in place of standard cat. 3" exhaust with Apexi Super Megaphone muffler (RARE) for street use AND 3.5 inch straight pipe for track use. Most reading this thread will know this turbo has made a peak of 391kw on JEMs dyno at 28psi on a stock RB25NEO with supporting mods. It ran most of its life on low boost and on track majority of last year it sat on gate pressure as i was setting up the car so power was not required at that time. This turbo setup is ideal for street or track, it just does everything well for what it is. It is one of the best sounding setups on full noise although it does lack the turbo whistle the old GT3076 had See above video for what it currently sounds like, this was from the 4th June 2017. Car ran a 63 at Wakefield on low boost The cost for the whole setup above is $3750.00 firm... Already have some interest just from mentioning the sale to a few mates so not splitting the setup or taking offers at this stage. Keep in mind the turbo has just had $680.00 spent on it with a reciept from 2 weeks ago. The 6Boost manifold also had a crack repaired under the collector, this was professionally repaired by Fabtech while the turbo was off getting rebuilt... PM me through here for more details if required. More pics can be taken if needed however here are a few off my phone -

Update, AUS TIME ATTACK at Wakefield Park we managed to shave a bit off our time and now have a 1.034

Turbo HTA was rebuilt by Precision Turbochargers in Wetherill Park back to new condition. They did it incredibly quick and pricing was decent too. The bearing had collapsed taking out the seal but as it was shut down quickly no contact of any kind was made by the wheels or housings which meant it was a simple overhaul and back to new It performs that way too as we just ran 50 laps at Wakefield Park for Aus Time Attack and just scraped in a PB of 63.4sec with plenty left in it... We have another round to go this weekend at SMSP North Circuit and then the turbo kit is going up for sale. It will be sadly missed as its been so much fun but i need something a bit more track oriented now the car is a dedicated circuit car... Ill post some details of what is up for sale below and then do a proper add in the for sale section soon... The new manifold has been started and pics will start coming through soon... Its exciting times just like 2011 all over again... Except without the " I am NOT aiming for big horsepower or a time attack machine, i am just aiming for an all rounder that is OK on the track and the street too..." comment that i still get shit about to this day Plenty of pics being posted on our Facebook and Instagram Pages, get over and give them a like to see what we are up too!

Bump, Still available... Now with added tyre options - $1200 with brand new Zestino 240 treadwear street tyres supplied $1500 with brand new Zestino 140 treadwear Semi Slick style street/ track tyres supplied. These Zestino tyres are brand new and are amazing value for money. These are currently available from K Racing if you are interested in purchasing separately.

Still available... Was looking for the offset but found these instead -

18in Works XT7 rims - Powdercoated Satin Black Hi Guys, I have had these Works XT7 rims for nearly 10 years as they came with the car when originally purchased. The rims are 18x8.5 and 18x9.5 and sit perfectly on an R34GTT with no spacers etc... Ill have to check the exact offset but i believe it was around the +30 mark from memory. The rims have been professionally sandblasted and powdercoated in a Satin Black to match my engine bay and car theme at the time. The rims had some rash repaired back in 2012ish (Check my build thread for pics and exact dates as its all in there)... This was when the powdercoating was applied. Genuine reason for sale, i held onto these for a few years after upgrading the car as i intended on getting another GTT for a daily but plans have changed and i would rather upgrade the race car instead. I currently run 18x10.5 rims all round due to the new widebody setup so these are no longer of any use for my GTT. The rims are off the car with no tyres fitted, they have been polished and stored in the house for the last few years so they are clean! I have an old set of 275 tyres for the rear i can chuck in with the sale, they were fitted to the car at some stage. I also have the original blue alloy Works wheel nuts, lock nuts and locking key, however they were removed from the car as one or two of the nuts had a damaged thread... I can get decent pricing on tyres through a good mate, if you are interested in tyres please let me know when you enquire and ill pass on the information. On the front rims i have previously run 235/40/18 and also a 255/35/18. On the rear i have run 265/35/18 and also a 275/30/18 (The 275/30 can be thrown in with the sale at no cost as they are just sitting in a rack). The rims are located in the Newcastle area. Not keen on shipping them anywhere just yet, would prefer the buyer inspects them prior to purchasing. If shipping must be done it will be at the buyers expense and although they will be packed the best they can be i will not be responsible for any damage caused in transit. Asking price is $1000 and is not negotiable. Best method of contact is via PM as it will notify me on my phone and ill get back to you ASAP. Cheers Mat

I was actually going to ask you when it was as i forgot lol... So long ago now! A fresh new turbo setup will be its birthday present and should be significant

Finally time to start updating this thread again now that ill be making some changes to the car... Up until now i have just been thrashing and having fun and ironing out issues and finally seem to be heading in the right direction with the car setup! It still understeers like a pig but i will be sorting the car balance over the next few rounds with some changes to spring rates and bars, will hopefully finally get on top of that! Its finally time to change the almighty 6Boost, Tial and HTA combo to something a bit bigger, its been something i have wanted to do for quite a while. The 6Boost manifold ended up with a crack below the collector which has now been welded and repaired, i have been chasing a leak for a while and it was in a spot that i couldnt see while fitted to the car, when i removed the turbo and manifold i located a crack in the welds of the collector so had it repaired by Fabtech this week. Kyle from 6Boost offered to assist with the repair however i didn't have the time to wait as i have 3 track days over the next 6 weeks. To get the changes done i will be placing some stuff up for sale, ill do a for sale thread when i could be bothered but ill be selling - R34 GTT Carbon boot lid sourced from Just Jap - Brand New - Never used Works XT7 rims powdercoated in satin black in 18x8.5 and 18x9.5 - Excellent condition (pics in this build thread of them on the car) 6Boost Manifold / Tial 44mm MV-R gate / Forced Performance HTA 3076 / Dump pipe and screamer (plumb back optional) and intake piping - good for 525whp Whiteline front swaybar end links KLC 108 - Brand new in pack (Ended up with 2 sets) Standard GTT brake calipers, pads and lines front and rear with 2 sets of front rotors (DBA4000 and Endless) - rear rotors cracked and are no good. If anyone knows someone that may be interested let me know as the faster i sell this stuff the faster i can do upgrades on the race car I am sure there is a heap of other stuff in the shed i could offload and ill spend some time over the coming weeks getting them out and taking pics etc... Here is some footage from Round 1 of the NSW Super Sprints, the car was pretty ordinary to drive with the understeer as you can see - Our next track days are - 14th May - Round 2 NSW Super Sprints - Wakefield Park 4th June - Aus Time Attack - Wakefield Park 18 June - Round 3 NSW Super Sprints - SMSP North Circuit We will have plenty more track days throughout the year and will continually chip away at the performance side of things... Ill try make more of an effort to update this thread with the new build progress and results as well as Facebook.
