Hey guys just got some new turbos fitted to my car and i thought id post the dyno graph up to see what u guys think. Running sort of a light tune to keep my engine alive during track days until i can afford to get a rebuild done :P . Its using a djetro pfc and still on a cat back. Plan to get a turbo back soon to try and get it to be more responsive. Any comments welcome. Cheers :D

what injectors you running?

Im running nismo 600cc ones.

3lit3 32, from what i know i should be able to easily get 500+ hp atw but i dunno about 700 heh. Yea I know im not even close to pushing the turbos but as i said, im trying to take it on the safe side for now as i do some track work. Once i get a full engine rebuild ill go all out >_< . The dyno run was on 2 wheels.

Cheers

Nice, what boost are you running? Looks around 20psi?

seems quite laggy to me. 1 bar at around 4500rpm. nice power though, but they must be fairly large low mouts as the resposnse does not look that great.

yeahh from what i know, the -5 model is slightly bigger than the -7 model, which (i think) is comparable to hks 2530s. Yeah it is rather laggy but im still running a catback so im hoping the graph shifts to the left a bit once ive got front pipes/dump pipes in.

yeah West im running slightly under 20 psi. Btw how do you know its in 5th gear? :P They are bigger than both the gt-ss and the N1s

Cheers

I was only guessing :bunny: mate.

Damn, those things are bigger than Gt-ss, mad fun their. May i ask what condition is your engine in? Did you do a low boost run? Say around 14psi?

west mate, it would not be in 5th gear. most DD dynos are rated to 200km/h only. It would be either 3rd or most likely 4th gear. Even if it was in 5th (which i can promise it wasn't) it shouldn't make much difference at all. if anything it may build a little earlier as the engine is under more load.

Thank you very much, i dont know much about Dyno thing.

Mind if i ask who or which work shop that did the tune?

Are you still running standard injectors? If so whats the percentage shown at 300kw?

D-Jetro is still very new to VIC tuning scene i think though i'd love to have it, just to get rid of the air flow meters.

Airlfow meters is what makes the PFC so powerful. D-Jetro I assume was made for the american market as they had no idea how to tune a MAF based system. If you want to go MAFLESS get an Autronic because the time/cost taken to wiring in and tune will probably about the same to plugin and tune a D-jetro and at the end of the day the autronic is better.

On a more advanced engine e.g Fully rebuilt , cams/head work and tune the lagg can be taken care of through playing with cam timing , while still not loosing any of the mid range top end punch these puppies deliver.Just take it to a tuner who knows the fine tuning insides and outs of the RB26 and you will be very rewarded.Should be able to see full boost 22 -24 psi at 4500 rpm or just under but they will start pulling hard much lower than this so are still a very streetable turbo set up.

Alot of the gtr forums I visit from around the world rate these huffers above 2530s for there response and big delivery of power in the top end.

On a fairly stock engine Id put a gtss or the 2860R -7 turbo upgrade ahead of these unless of course you are taking it further down the track,these are purfect for a hard tuned street machine.

On a fully worked engine these turbs are good for 380 - 410 awkws

Just my opinion though. :)

one questions I have always wondered is assimung ur've upgraded your turbo, AFM, injectors, fuel pump PFC blah blah and your making a good 300+rwkw...at what point do u need to consider internal upgrades or is this dependant on how hard you drive it? In a street app where you may only trash it occasionally...I'm wondering how the internals hold up over a 1-2 year peroid..on say 1bar or just a little over.

Just intrested as I have a RB25 with the same mods and similar output as this dyno i.e. about 300rwk on 1bar and all the goodies...now I'm wondering how long the engine will last hehe.

I got an r 33 GTR with a built motor and same turbos and im pushing 366 kw at all fours on 22 psi and pump fuel. My car makes 308 kw at 5600 rpm id post the dyno sheet but dont know how

    • Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes 
    • 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.
