Hey guys was around at C&V just then and saw the Hypertune civic just make 365KW at the front wheels just with boost, no gas!

They said it was with only 24psi.

The car is still 1595cc and revs to 11,000RPM!!!

They may up the boost more tomorrow at C&V's Dyno day. I'm going out to see it run next wednesday night.

Cheers

Now thats some serious vtec yo

The power curve would be interesting, civics are gutless in the low rev range in NA form, lowering the compression so you could run a decent amount of boost would kill it.

My money is on it coming on full boost at 10k :O

why are we even discussing about a honda. I hate honda and everything about it. I have even heard some honda dudes day vtec is like boost,can you believe those idiots. i say rev all u want bitches, i know when we stand side by side on a drag strip i know that ill Be putting my power to the ground ;). stay on one place and burn your tires.

Yeah - this shows how good your knowledge of turbocharging is! Car still runs a high CR (9.4:1) This thing has a powerband that is over 5000rpm wide - no boost drop off between changes at all. Similar power delivery to an RB26 with a big single.

Yeah BLRCRX (james) here in Melb did similar things/numbers way back when, although i dont know the full specs, its a mighty feat without a doubt

James originally built his car to Hypertunes specs, his engine build was based on this car. This little civic is running on a 6 year old bottom end (been over 320kw at the wheels for this length of time too) and is still going strong!

I was back at c&V today(holden Vs Ford)dyno day.

They got the little civic out again, this time with c16 and some new plugs.

They started to get the car going again but they blew a tyre, then they got some new ones on to only pop a drive shaft.

They left it for now but they will be running the car this wednesday night still they said.

I hope all goes well for them and they get the MPH that they want(140).

Marks car from hypertune is crazy i have seen alot of work they have done over the years some of the custom work the do is crazy so if any of you guys need soom work done get them to do it they know there shit.

haha I won't deny that one :)

In all seriousness, how can you compare a 1.6L engine to a 2.6L?

You can't tell me VTEC would make that much difference (if any at all) to a conventional engine running a high lift cam when it comes to high rpm power delivery.

Or is it just cause it can rev higher?

If all other things were equal a 2.6L would flow 62.5% more exhaust gas at the same RPM right?

so having a 1.6L at 11k RPM would be the same as a 2.6L at 6750 RPM?

In that case I wanna see a 10k RPM RB20 running a TO4Z :(

Your are missing something important frost...Its called Volumetric efficiency!

Otherwise by your equations we'd all be trying to stuff 454 big blocks in our skylines :)

BTW top effort on the figures must sound insane on the dyno at 11k :)

    • 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
