No noise day = PIARC day?

Yep! :)

The thing was maxxing out its GTR injectors with a belly full of corn syrup so not a lot of time was spent trying to get a result, just a few dyno pulls to see how it behaved. So its hardly an exhaustive test and tune with E85, its just a little disappointing that other cars fill up with E85, load more fuel and ignition and they readily show signs of making more power vs my car that seems a little more stubborn.

Fark Garret fluff..i have a an army of Mitsubushi turbos that will go on before I soften up and go roller girl bearing

Just need to sell a few more parts so that I can play with the R32 whilst rebuilding the Sierra :)

We knew it was going to happen, just wanted to try the corn juice to see if the engine liked it and whether it helped its tendency to ping. I think if nothing else this test has told me there is nothing magic about E85 and if you are out of compressor flow then you are out of compressor flow and E85 will only give you a few more killerwasps :(

I have not bothered as the 20G with a 10cm housing was too big for an RB20. So I am betting a 25G would be rather ordinary on a 20. Would probably make a good number, but would make less than 200rwkws at 5,200rpm :( If i had a freshly built RB20 that I knew was well balanced and had a good oiling system it would be probably a decent enough thing to spin up between 5,500-9,000rpm.

If I can sell some of my fluff laying around I could quite possible give the T67-25G a nudge. The crime will be is if I run it with E85 and the 10cm housing I will instantly losing $300-500 as it is brand new. Think I will have enough trouble selling them with the Kando things running around but not fussed. Some of the gear I dont really want to sell, just need to move enough to clear up some funds for further work on the R32 and Cossie rebuild

The 25G wheel is 15% bigger than the 20G wheel, so with the little 69.7 mm stroke of the RB20 and 8.5:1 compression, like i posted above I dont see the RB20 doing a bang up job of getting the most out of the T67.

That's why I grabbed the 73HTA wheel, it is only 7% bigger but is lighter so stands a chance of spooling as well, if not better than the 20G wheel.

But for now I have decided I am going to shelve the plans for the 73 HTA and see if the lil std motor can handle the corn syrup and the power it makes with the 20G for a few track days.

I figure 306rwkws is a decent enough step from the power I was previously running and now getting into the area where I am less confident about how well a std engine with at least 60,000kms (i have put those 60,000kms on the wrecker engine) will do with that sort of grunt, boost and revs

I'd say its the turbo. they are only a 450hp turbo arn't they?

The way the boost trails off means the engine is taking more air than the turbo can produce. If you have a smart enough boost controller you can get around it. But the turbo will hate life

    • 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
