The 1JZGTE has .2mm shorter stroke, or 71.5mm vs 71.7mm for the RB25DET and they both have 86mm bore... RB25DET > 1JZGTE In the cases I have seen so far RB25DETs keep making more power with untouched (ie cams/porting etc) heads than the 1JZGTEs. On stock turbos the 1JZGTEs do better however, but thats because the 1JZGTEs come with better turbos. There is no questioning the 1JZGTE is stronger, though having said that I have been running mid/high 200rwkw for a couple of years ago in my daily driven R33 with no issues whatsoever from the engine and I don't expect it will start so I guess it depends on what you are looking for.

Not agreed, in my experience the RB25s seem to flow a bit better - ie more power on less boost. But yeah, the 1JZ is a stronger unit. The exhaust note is because of the exhaust design, get a tubular exhaust manifold on both and you'll find the engines are very very similar sounding... 6boost manifolds make RB25s sound pretty wicked

Gotta love the "Taxi" spec cars that will scare a lot of punters. One of my mates has an old 3litre Maxima he has managed mid 13s (13.5 I think is his PB) out of an NA running only bolt on modifications! Absolutely

Ahh I've seen a lot of this kind of thing, and I suspect I might possibly know what the deal is - someone who knows how to drive/willing to thrash their car racing against people who don't. Street racing can mix things up a lot as well - you don't get elapsed times and reaction times to work out who went when etc. It does sound a bit like your car goes ok and you know how to drive it, and particularly it must have a good amount of available torque. The funniest car I had was a Honda Domani (1.6litre single cam non-VTEC) which I used to have the odd run on the road with mates of mine's cars - up to 100kph or so it was able to hold off if not keep ahead of some of these high rev NA "monsters" such as 20v Levins, 1600vtec Integras and in one funny case a 4door Type-R Integra. Above 100kph it suddenly looks like I am not fully committing though despite being hard on the throttle People still were bemused at how well it went against things up to 100k, so we put it on a dyno somewhere along the line and instead of discovering it was a magic ZC it turned out it was just a normal one but had been holding off things with 60% more power up to 100kph due to every ounce of its power being used up to that speed while others are wheelspinning/doing poor gearshifts etc and then when it comes down to the power game just dying. No need for apologies, nothing is personal in such threads - its all in good fun

Carby, I presume? One of my mates have cracked into the 13s with a not overly modified VTEC CRX. In NZ we have a scoreboard of the quicker times done by NA Hondas, before anyone gets excited about stripped out/slicks cars - they have to race as "pro import" otherwise they have to be legal tyres, interior, exhaust so this score board has it listed. Times on the board have to be proven, so its not just made up stuff. There is a cut off below 14.4 because otherwise the list would be way too big... most virtually standard VTEC Hondas with a decent driver will do 14s. http://nzhondas.com/forum/competition/4411...core-board.html

Its in the wrong area, its blatently turbocharged. There is nothing remarkable. There are RB30DETs based on NA RB30 bottom ends running around all over the place making >300kw @ wheels on the stock internals and you don't see any of those guys posting their NA dyno results in this thread. The reason is, they are no longer NA. Much like you. Have people played around with decent cold air intakes, using ram air or anything?

This is true, but thats not the fault of Honda owners. You may get it more often with Honda owners as the entry level "performance" Hondas are cheaper than the entry level "performance" Skylines so you end up with younger and more predisposed to that kind of behaviour people owning them. There are an aweful lot of Honda owners who do not think that way.... I would say the vast majority of the ones I know are some of the more switched on people I know.

Not 100% sure what your point is - those types of threads appear in all sorts of forums. I couple pick any, hell this one is pretty sad. Someone even implied their NA R34 can deal to 1.8 VTEC Integras, that kind of talk belongs alongside a thread about a dude claiming his VTEC Integra can smoke GTRs. As usual in those threads there are some with wool over their eyes and others who are saying "WTF mate?"

I feel there is probably something missing from this story - like his car being auto, or you have already got 20kph on him before he floors it, or something along those lines. I remember a dude with an RB30DE R33 that used to be convinced he was catching a mate of mines Integra track car on the straights etc - he had in his head his car was quicker almost everywhere yet somehow the Integra was around 10s a lap faster (for ~1:20 laps) and to everyone watching the Skyline may as well have been cruising around the track. Horses for courses, people seem to be acting like Honda guys think their Civic would smoke a modded GTR or whatever but I haven't seen that mentioned anywhere in this thread. Here is a vid taken from a good mate of mine's non-Type-R Integra car taken at the local race track at an open day, the two Skylines you see in it are a grey one (RB20DET with a TD05 - making about 200wkw) and a Burgundy one (RB30DET with T3/T4 making about 250kw @ wheels at the time) are other mates of mine. The blue KP Starlet in the vid runs a turbo 4AGE.

No one ever said the Hondas are better than the Nissans - especially an RB26DETT. That comment means nothing - what sounds better, an RB20DE with a fart cannon or an RB26DETT? Hell even the VTEC sounds 10,000,000 times better than an NA RB. R33s just adjust the cam timing, Hondas have two stages of lift as well which is what makes the real difference. A base model VTEC Integra with a turbo on the side of it running 8psi of boost will make power comparable to your typical RB25DET using only a 1.8litre engine, take into account that its in a light car it makes for a seriously fast little car for not a huge amount of money.

I am 110% sure. Check this link, and on that page you'll see links for the progress of each year - you'll find you are thinking of the same car and that it has just had huge progress over the last couple of years. John went from GTArt to Abbey Motorsport and from RB25 to 26 when things started getting really serious:http://projectgtst.com/index06.php

Haha yeah those things are awesome, very hoonable and light as so don't need much. There is a guy with one of those and a tinkered with B18C which has done mid/high 12s as a street car - no reliability issues again.

Actually that car is an RB26DET with a T62R and run a high 7 now Heat Treatments are the most powerful I know of, "over 1200hp"... has run over 190mph on the 1/4 mile. Considering there are ">1000hp" GTRs which have only cracked 160mph, it must be making a fair bunch.

Thats nothing to do with VTEC, thats to do with engine size - VTEC doesn't make it a bigger engine, or like a bigger engine.... it allows something to be a tractable reliable economical race motor. A 1.8litre VTEC motor for example will be no worse than a standard 1.8l 4cyl NA motor in driveability if not a little torquier/responsive due to compression head design and engine balance but also angry up in the revs. It doesn't compromise torque at all, it just means that its torque doesn't match that of a typical turbo or bigger displacement motor with the same power. Bolt a turbo onto a VTEC motor and you start making other turbo motors look average....

I tend to feel that someone who gets up on their high horse when someone else is happy with their equipment can't be too happy with their own...

Its very clear that many Skyline drivers still have tiny penises. I for one am a big Honda fan, it seems a lot of you seem to assume because someone is enthusiastic about their car means they think its better than everything or more than it is - you have to take it as all relative. Hondas are awesome fun to drive, I have actually just bought a Japanese import Honda Prelude (my 2nd 2.2VTEC one, my 5th Honda) and for day to day use it actually puts more of a grin on my face than my 280kw @ wheel RWD Skyline. These people raving on about these things having no torque, it would kill my Skyline from low revs and makes my Skyline feel more like a "need to rev" type car - albeit the Skyline would kick 7 shades of shit out of the Prelude once it gets a bit of boost on but again, I own the two cars for different reasons. The Prelude is something I can thrash around without worrying about it breaking (whoever said fast NA Hondas need regular rebuilds have been around too many bad tuners/engine builders), someone bumping into it, or going too fast to quickly. People may think that VTEC Hondas don't have any acceleration, but to be blatently honest after running around for a couple of years with a turbo Skyline with reasonable power I can still get a kick out of when the Honda winds up and goes when I need it to - there are no big risks or planning sessions required to work out how to overtake people, and more grins than frustration when thrashing it. Sure it doesn't blow me away with mighty acceleration, but its got enough that its not a waste of time revving it out and because its not a Skyline/Mitsi/whatever I can rev it past redline day in day out and can stay confident the rods will stay where they should be. Its exactly the same as when I go in a majority of other turbo Skylines out there, they have enough of a push in the back to tell you that its going but it doesn't blow me away - its still fun though. I don't take the piss out of people who have got their first GTSt with cat back exhaust and are rapt with it because my own car will shit on it from a great height, I don't see why people should do the same to someone who has got themselves a car which gives them the same jollies but they have the added bonus of not getting raped at the service station, not worries of ceramic exhaust wheels smashing, ring lands breaking, coils breaking down, etc etc.

Your criteria has got more refined every post. A privately owned full weight (+ cage) street R34 GTR did a 9.7 1/4 mile in NZ on its only run not long ago but that again was in NZ and went to the UK. Things like that aren't rare though, I'm sure there would be more like that around. I have been getting the impression that RH9 in Oz could be able to but is more of a dyno queen? To be fair, if you want to own a fastest anything that anyone is going to pay attention to you should aim at running 9s. I have heard of a few Oz R34s that would be able to do 10s if they bothered, and may have.

Whoa shit, sorry to hear

No that was a completely different event, I didn't even manage to get a run that day and it was the only time I had >200kw at the wheels with stock turbo.

In all seriousness I actually ran 14.1 with stock boost, pod filter and full exhaust. I'd expect to run in the mid/high 13s with a front mount and a touch more boost.

I've always taken the -7 to be more like an N1 equivalent... it seems the first person to be heard to say something about a topic (ie, -7s = GT-SS) is the one thats right and it takes a lot to get it set right if they weren't.

The -9 is a bolt up too as far as I understand. The airflow thing, there is no magic conversion - its all basically thumb sucks and the fact that Dynamics dynos read stupidly low probably mean the estimates go all up the wazoo. For the dynos that I am used to the calculations all seem to match up quite nicely and everything has worked out well so far - within reasonable margains of course.

14.1 @ 98mph

Thats exactly what I meant, I must have had a brain fart and wrote the CHRA # instead of the whole unit's part number - my bad

Sorry I'm not 100% sure what you mean by that question - do you mean how much more to the right can the RB be made to go, or how much more airflow can you get from one of those turbos? You should check out Garrett's GT2560R (466541-9) compressor map, quite interesting reading.
