Use the GT2540s, give the GT4088R to me... I won't fluff around making my mind up, I'd just put it on because someone bloody has to

Very nice, love the styling and the wheel choice is hot. Not too sure of the Maxima (!?) Nissan badge in the front though.... Very similar style to a mate of mine's old R33:

The only chance the R33 has is if something goes seriously wrong with the Aristo's run, they really don't mess around. Almost any single one of those mods on the Aristo would have been sufficient.

Or Rob will

The thing busted out four 7second passes today too, not bad for a stock crank!!

I will post vids if or when any become available

Congrats Rob and Co! You must be rapt He ran 4 7s at a meet today at Meremere NZ, all at around 176mph and the fastest of which a 7.89 @ 176mph (basically in limiter in top gear) after tuning the car for a bit more boost this week. Still running the Nissan crankshaft! What is the fastest RB30 powered drag car anyone knows of?

Yeah I can see that it should do, just find it interesting that although I haven't seen a huge amount of results for Neos running upgraded turbos etc - none of them so far have been that flash. Definitely not anything substantially more than R33 RB25 results, people have even given examples in this thread.

To be fair though, you've generated a bit of a strange bunch of variables to have to meet. I am sure there are plenty of standard R33 RB25s that have made around 270rwkw with an HKS GT-RS, they just haven't decided to go and get runs on different dynos as most people stick to a single tuner. I remember years ago when I was researching turbo upgrades for R33 RB25s 270rwkw seemed like the number to go for with one but I decided the GT-RS would start wrecking the fun when I got more power hungry. I'm not sure what you are trying to prove, its known that R33 RB25s are well capable of going over 270rwkw with a standard head so the engine is not your limiting factor in this case.

The RB30DET takes the credit really, which is the first thing I went to. That R33 RB30 conversion thread is quite hard to manage.

OK my apologies, I could swear I had read the RB30DET guide and that it talked about space in an R32 GTSt - not an R33. I had another read and it answers my questions perfectly. Maybe I did something blonde like interpreted a useage of "GTST" somewhere as meaning an R32, over here R33 "GTSt"s tend to be referred to as "25T"s. Either way my bad. Cheers for the help guys

Edit: I guess I have my answer, it can be done with with effort. Thanks Guilt-Toy, kinda.

Hey guys, sorry if this has been covered somewhere - I have done quite a bit of trawling and there is HEAPS of information on building RB30DETs and even information on squeezing the RB30 into an R32 in such a way as to not get clearance issues but I've not found anything specific on the R33 (which obviously has a different engine bay and factory deck height), and I figure there are bound to have been people who have tried here so someone should be able to provide an easy yes/no answer and I am sure someone else would do the same search. Are there any clearance issues when putting an RB30 bottom end under the stock RB25 head in an R33 GTS25t when retaining the stock plenum/cross over pipe, are there any basic mods to make it work, or is getting a forward facing plenum imperative to making it work? I quite like my turbo setup etc, the stock plenum and exhaust manifold are definitely capable of making the power I want... I am more looking at the 3litre for reliability (addressing oil control and having a fresh engine as well as the fact the 30s are tough) as well as the obvious huge boost in power delivery of having a 3litre are the big motivators for looking into this as the car is primarily daily driver vs drag/track. The added cost of having to change manifolds, piping etc would sway my decision on whether I'd go RB30 or not. Cheers, Lith0r. PS, I just realised/remembered there is an RB30DET area and this probably should be in there but can't move the post myself

I'd try doing a compression test.

How are you testing the EGT? Any chance you have a leaky blow off valve or some other intake leak forming?

If you look at the title it said "No chit chat, just results". I think its very fair to have assumed he had no intention of providing much more information. If it was "My new drag car" with the same attachments then it would have seemed more like a teaser. Either way good luck with the car, looks very serious and look forward to hearing strip results - cool to see someone is using one of those auto setups, a lot of GTR folks seem to have a grudge against them despite them making a lot of sense.

No question of that, it looks like something if the setup is right should go into the 8s very quickly.

Haha can you elaborate on which one is your choice?

^^ Does nothing for me

Initial track results are in for 370Zs, on Tsukuba they bust out a 1:06.6 compared to an R34 VSpec2's 1:06.3 so the V-Spec JUST nudges it out but it'd be a good race.

Yeah its starting to look at it that way. I'd treat it as an equivalent of a GT3076R, or roughly a 500hp turbo.

There's a pretty neat new number added to the RB30 dyno results thread - more power, no methanol in a car which had already done 8.05 @ 173mph with its old tune: http://www.skylinesaustralia.com/forums/Rb...0&start=60# At least gives a bit of info and you can easily find videos on youtube as well Fingers crossed the weather is fine in Auckland this weekend, then there should be a bit more of an update on the car

You did look at the comments on GT2835s on a Neo and a R33 RB25? GT2835 is barely different to your GTRS. A bigger turbo doesn't magically tend to add more power on the same boost level unless the smaller one was becoming inefficient on the particular motor its on. At 270rwkw you are pretty much getting into "outflow the GTRS" type territory, as such you never know - with your bigger cams/"race porting" you could have been elevating exhaust pressure to the point the turbo was choking and causing reversion and your tune may have had to have been pulled back to make it safe, and a stock R33 head may have actually been better for you. If you were talking GT3582R and tried that on both your car and the R34 (and whoever did your "race porting" did a good) then maybe the results would have been vastly different. Your results are at odds with a lot of stuff I have seen. The reason I asked if you got a before and after is not for our benefit, if I were going to invest the money in doing a whole pile of head work I'd seriously be trying to get a before and after comparison with no other changes to make sure it has worked as I had intended. Messing with the part which dictates how the whole setup works is a good way of making or breaking a setup, quite frankly I take "Years of research" etc etc with a grain of salt. It doesn't mean they didn't have a bunch of monkeys doing the R&D, spending lots of money doesn't necessarily make something work and having a head with big cams and flow numbers doesn't mean its going to work optimally with the other parts you have bolted up to it.

Nice power, whats the setup? Where are you based?

Did you get any before and after cams and race porting dyno plots?
