Gt35r Vs Garrett T04z - Discussion (just Post In This Thread To Create A Database)


Recommended Posts

i was comparing simons 625hp not my own setup nick.

cerbera thats something i expected from you on a forum, just your style lol

borg warners are where its at :P

come on its a matter of personal preference i think, everyone has there own ideas of lag/power/fast.

pretty much the same engine/turbo but one has 6-boost twin scroll and one has china manifold and a dodgy gate

shows what a well set up manifold/gate/boost controller combo can do...

Would it be possible to overlay a stock curve for those following at home?

Ah ic ic - makes more sense now :P

Would be interesting to see the GT35 on a good setup i think, one thing that's missing from the comparo's haha ;)

Here is a graph of my GT35 with .82 rear on a decent manifold setup

also i plotted it on brockas graph to compare, its the black line.

diff ratios dont seem to be the same and isnt yours a RB30 therefore totally useless comparison?!?

lol ye exactly - twice in as many days... stand back george :)

Thanks sky30 - but kinda... not really relevant unfortunately :(

Didnt realise that its a RB26, for some reason i thought brockas was a RB30det, That would explain why it seems so laggy to me. Oh well interesting comparison between rb30 and rb26.

Its a r32 gtr diff, 4.11 ratio, what are the ratios in the other graphs?

Car should be running in a week or so. And i'll head to the plex again see if it can go decently into the tens on street tyres. To4z has the top end to get decently into the mid 130mph's. With the small things its had done to it this time round 650rwhp should be enough for mid tens on street tyres.

I'd love to see a GT4088R compared with these things :D

lol give my bank balance time to recover after this change in setup first!!

I've now taken 2 people for a spin in my car. They both saw the graphs before going for a drive, and said the exact same thing. "It doesn't feel as laggy as it looks on the dyno plot".

Would love to have it snapping on boost hard, but I don't think my gearbox would like that...

Just looking at Pauls Graph compared to mine as a t04z to to4z comparison seems to be quite a bit of difference in response. They are both roughly based on speed vs hp and at say at 130kms pauls is making 220hp ish and mine is making almost 400hp at the same speed. Just an interesting comparison as mine didn't really feel laggy at all and should be better with the new setup of bigger valves and bits and pieces. As a comparison mine was running 27psi and i think pauls is 25psi so pretty close.

I think you can put it down to the boost control.

You can see in your graph the boost comes on hard where as Brockas is a bit lazier. A good boost controller makes all the difference.

LOL

no chance you will have it running in a week or so!!!

Indeed arguable. Effiecent range on the GT35 is probably 28 - 30psi and 35 + on t04z.

Brockas like most probably not keen to push to those levels.

All your graph comparo proves is that brockas china manifold / setup is crap compared to 6boost and your setup.

GT35 on your setup would have rocked.

LOL coming from the guy that never raced his 26 !!! Simon N has times you got wannabe ......

Final word

IN PERTH GT35 smashs the t04z on RB26. Best single t04z time is like 10.8 on a fully built motor ??

There is more then one GT35 RB26's quicker then that IN PERTH.

RockoGTR's 10.4 on Nexan Radials is a GT35 and China manifold. We are going to put it on E85 and MT Drag radials and try again.

I now have one of the best boost controllers on the market, the Blitz Dual SBC Spec R.

Unfortunately, it's my wastegate which is letting me down.

Simon, we overlayed yours versus mine and yours destroys my setup everywhere. It's on earlier due to the head porting, but yours snaps on boost so much harder. I think once I sort this wastegate issue it will change the midrange dramatically and also carry a few more HP to the top.

For now though, I'm going to see how long this $300 2nd hand box lasts... the fact that it lasted the dyno run means it's been good value so far...

Natto it will be interesting for me to see if your car can repeat the 627. That is a 4 year old dyno graph your clinging on to. Dyno's get worn, software updates and re-calibrated over that time.

    • I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.  
    • Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days
    • It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
    • I assume clearances were all a-okay?
    • Shock tower brace is in +5Kw....LOL
