Yeah, it was great having an exhaust probe in there tracking things - and spotted some shady boost behaviour etc. It lays everything out on the table for you. I'm just using an S-AFC2

Yeah, cheers Its quite funny, because I'm (obviously) really stoked and I was talking to someone recently who realised what my new power figure was and didn't see why I was quite so happy. The power figure is good, but getting up and going - and pulling through the midrange is meaty as anything. Feels like the 2.5turbo has been pulled and a big NA motor that revs to 7000rpm has been put in, 10-11psi is being reached by 2400rpm (lower than I expected - not sure what normal is). The area beneath the curve makes it feel to me like an all around much faster car, and just more pleasant to potter around in too I definately rate dyno tuning as a very important step - even without trying it at the strip... its obviously made the car more responsive etc, which has to be worth something in practical terms.

One step closer, raised the boost to 11psi and got it dyno tuned - feels like a completely different car. With the current setup I figure very solid 13s should be achievable, I think a bit of work including other-than-power stuff will be needed for a 12 .

With a tear in my eye, I can honestly say - thats beautiful :wassup: Very nice setup there, look forward to hearing about how it actually works out!

I know its clutching for straws, but check all your piping which gets pressurised - you could have blown an intercooler hose or something like that, car is throwing in fuel for air it isn't receiving when it comes on boost. Just adding a possibility to the mix :headspin:

Its all about traction with FWD NAs, one of my friends did 13.7 with the above mods + semi slicks on a non-TypeR 1.8VTEC Integra. The VTECs go very well for NAs, my old VTEC Prelude managed 141fwkw with basic bolt on modifications + dyno tuning - which gave it pretty respectable (even by turbo standards) acceleration, though bare in mind in NZ most of our cars seem to be Jap versions - which go better than the non Jap ones right from the start. Obviously, no way near as much fun as a Skyline - missing the RWD factor primarily, but if you have to worry about insurance etc they are definately a good idea. I bought the Prelude to keep me happy until the expense of a turbo was something I could live with A normal VTEC Integra with basic mods will even make a very good car to blat around in until a turbo is doable.

Very difficult, but possible - I have watched an R32 GTSt w/ RB20DET run an 12.2 in NZ, but that was using NOS and slicks. Esp. if you want to do it with a road car/street tires, I'd guess an RB25 would make it heaps easier - just because of the response/turbo driving ability.

Settle Gretal, he was sticking up for you from the people changing the topic to a vs. conversation. Worded differently - "All he wants to know is who has done a RB22DET, or how is a good way to go about- because that is what he wants to do".

That would be cool But yeah, realistically in NZ people more often than not short change R33s - so they have hardly been bothered with... most people prefer the R32s, and see them as a better performing car - so thats where more of the knowledge lies, and there is a lot of assumption. Obviously in Oz you guys are more keen to mod R33s and research ways of getting the better results... so its always good to look where the proven information is, rather than ask people who more often than not don't even like R33s, and in many cases havent even been in them how to mod them - so aren't exactly reliable sources

No, not at all - I haven't had any problems with mine at all... but so far I have only been running around on stock boost, untuned SAFC and a catback exhaust - so no real stress for it YET I run 255s on the back so I am a bit worried that after the car is tuned with a bit more boost - it might get a bit more upset. Anyway, keep up the good times guys! I'll watch with interest how you guys are going and see if I can get an R33 representing a little in NZ as well

Awesome! Congratulations, thats very impressive without heaps of mods. In NZ the quickest R33s are barely touching into the 13s I'm just a n00b here, but I have been quietly tracking your progress and soaking info, because I have been building up parts for my R33 - and your car for a while had very similar to the mods I decided to do for my "first stage" (cold air intake, cat back exhaust, and S-AFC2) and read quite a few posts re: your car and S-AFC tuning which looked very positive for the direction I was heading. What clutch are you running?

All I was doing there was setting the facts straigtht - the only R33 you have officially raced you got beaten by, and the R34 did an ok job considering how few mods it had relative to you given it won the first race - you both had the poor traction disadvantage to contend with. The difference in mods thing (in favour of the R33) is part of my point, you said yours is faster than most of the 33s around - all of those are a lot more stock than yours, and yours is also quicker than the equivalent r32s.... it was a pointless comment. Also, the GTSt that ran low 12s - you said in your post low 11s (so even if you were told high 11s, you were twisting facts), and ask him yourself why he was using the NOS - and he was using NOS all the way from what I remember him saying. Ask him yourself, he posts as Trust Dunn on Skyline forums. I didn't realise you already had a RB25DET crank - if you do, then I the 2.2 idea sounds very cool.... if you don't (the only RB25 cranks I know of at your place belong to Mark and Jeff)... I'd considering the RB26 crank, as you dislike Rb25s so much - and given the amount of work you'd have to do etc, a 2.4 would be a lot more rewarding. You can borrow my HPI mag on their build up ideas of an RB24DET (rb20det based) - basically in concept the RB24 would be at least as torquey as an RB25, and still be based on the RB20DET block- so you get your cake and eat it too

I hear some whale defending necessary! You have hardly any other RWD skylines around which can keep up with yours, and from memory the ones that have at all are 33s or 34s (ie, RB25 powered). From memory the only R33 you have raced at the drags beat you - and all the other 33s around here are virtually stock (at the moment), and all this is with the RB25 in the heavier body. Also, dyno figures wise - the R33s on average are way higher powered at CF than the R32s, yours with bigger turbo, S-AFC etc was in the middle of the cat-back exhaust and pod filter R33 brigade - so the RB25s are actually making more power too. An R33 with a road tuned S-AFC and bigger turbo would be in a whole different power/performance class. The GTSt you mention was doing low 12s on slicks, and needed NOS because with the RB20 was unable to spool the turbo well enough for a decent launch - and has a built RB25 now.
