Hi guys,

Just wanted to hear your thoughts on this... I used to own a Honda Accord VTEC 3.0 ... it came with a supercharger (not sure which one) but it went... the roar of the V6 VTEC engine would send shivers down anyone's spine... now that I drive a R33 beast... it too has power but if the two would be pinned side-by-side in a quatermile sprint...which would win do you think?

I noticed that with Skylines (Turbos of course)... it has highend power and no so much lowerend and the opposite can be said for VTEC Honda's... is there a way a Skyline can be tuned to have high power in the lower RPM ranges? Is there so controller or piggyback ECU that can adjust this or is this just how a RB is designed?

Thanks in advance...

Thats because you had an 3 litre V6 obviously it would feel more torquey down low than an 2.5 litre RB. More to do with displacement than anything. In this case the supercharger contributes to the low end power too.

In fact most VTEC Hondas are 2l, 1.8l and 1.6l. These are famous for their peaky top end power not torque. so VTECs in general do not have more low end power than your RB.

There are many ways to improve low end power: Increase displacement e.g. RB30 conversion:). Aftermarket cams and etc..

Cheers

i thoguht the power range in vtecs it higher in the rev range in th elower rev range ti just saves petrol doensn't it? n the revs are longer as well tahts'w ot makes vtecs have the performance they have rite?

but all in all i reckon comes down to the driver :D

...it too has power but if the two would be pinned side-by-side in a quatermile sprint...which would win do you think?

the skyline would win (imo)...if u launched both cars the 33 would be faster....

ofcourse the 33 would seem slower wen u just takin off normally, cause of turbo lag.....superchargers as u prolly know eliminate this lag + a 3ltr is gona help.

u dont have to spend much money on a skyline to get it moving faster...turbo bak exhaust, ecu, boost, fmic, done, and alot fatser than a freggin accord.

EDIT: off the line ull always struggle if u dont launch a skyline...

I have raced a Vtec integra 96ish model. He has exhaust and air intake. I had catback on series 1 33... Off the line I got him (comfortably) but top end, Was absolutely neck and neck. I Love the sound of the Vtec when it kicks in.

Although I absolutely adore and love my Skyline to bits... I have to say, if the R33 had a 3.0 litre VTEC-alike engine in it... damn... a new monster would be born... I kinda miss the VTEC yo! LOL

jesus f$cking christ, what a disgrace

    • Just had this happen to me too.  R32 GTR.   Also broke "just before going out onto the track" - someone up there is looking out for us... Very scary since I was about to do a narrow street course with zero run-off and curbs everywhere. Many people on here upgrading to billet uprights and R35 bearings?   Or buying new OEM knuckles?  I am not keen to replace with another s/h 30 year old fatigued part.
    • Top off with distilled water and see what happens. If you keep losing coolant then you know to start looking.
    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
