Roo Posted November 1, 2007 Share Posted November 1, 2007 Hey guys and gals, i've just recently joined the the forums, and I'd like to introduce myself. My name is Roald, but you can all call me Roo.... its easier Now, I don't drive a skyline, but i do have a RB30DET (25/30) in my VL Calais, and I figured this would be a good place to get some good info on the newer nissan tech, as the VL sites i've become accustom to are more 'SOHC oriented'.... I have some Q's regarding my setup etc. but I'll get to them at a later date (studying....) Looking forward to getting involved, Regards, Roo Link to comment https://www.sau.com.au/forums/topic/191734-new-act-member/ Share on other sites More sharing options...
S04R3R Posted November 1, 2007 Share Posted November 1, 2007 Welcome champ. I haven't been on here too long but everyone seems pretty decent. Sounds like your car is a bit of a weapon. Do you have any pictures of the setup? Link to comment https://www.sau.com.au/forums/topic/191734-new-act-member/#findComment-3448767 Share on other sites More sharing options...

Bullet32 Posted November 29, 2007 Share Posted November 29, 2007 (edited) 148rwkw? Are you sure that figure is correct? You should be making a lot more than that... No offence intended.

datto260Z Posted November 29, 2007 Share Posted November 29, 2007 But what a torque figure, forget kws. For 6 psi, thats sweet as. Link to comment https://www.sau.com.au/forums/topic/191734-new-act-member/#findComment-3505600 Share on other sites More sharing options...

Roo Posted December 1, 2007 Author Share Posted December 1, 2007 148rwkw? Are you sure that figure is correct? You should be making a lot more than that... No offence intended. None taken .The reason for such odd Power vs. Torque figures is due to a rather restrictive intercooler. Between about 2100-3300 rpm I have access to full boost (10p.s.i), but by the time I've reached 4500 rpm its all the way back at 6 p.s.i You can see on the dyno sheet where the boost really falls off. Once its gets up on the revs, the cooler simply can't flow enough air. Correct me if I'm wrong, but I think this setup should really start singing at around 4000/4500 rpm, right where its all over.... I'm condisering sending the cooler to Garrett for a recore (Nizpro tanks are good as far as I know?) and getting the turbo high-flowed/steel wheels. Any other recommendations? Will I need a fuel cut defender (sometimes it surges/cuts under boost at lower revs - i.e. full boost to manifold) or rising-rate reg?

GeeTR Posted December 1, 2007 Share Posted December 1, 2007 Welcome, love the purple! Get a 4" IC with decent end tanks. Leave the fuel reg. Get a 044, inj's, ECU and GT35R and ram some boost through that thing Link to comment https://www.sau.com.au/forums/topic/191734-new-act-member/#findComment-3508276 Share on other sites More sharing options...

Well if you want to get the most from your engine set up (RB25 / 30DET) then I would suggest a fairly large low mount turbo such as a Garret GT30 / 82R, dont bother high flowing the one you have. Im using a GT30 / 71R (slightly smaller than the 82R) and it is good for about 250rwkw, the larger GT30 / 82R will be better for your engine because you have more down low power because of the larger capacity and it will probably spool a larger turbo pretty quick. If youre going for out right power then you will need a fuel pump - go for a Walbro in tank or Bosch 040. You'll also need to upsize your injectors as the standard ones will max out pretty quick, go for some SARD 550cc brand new squirters, dont bother having the standard ones high flowed. As for your intercooler, I have been using a Just Jap / Cooling pro 300 x 600 x 76 front mount for a while and Ive never had a problem, I would highly recommend one for the price. Get in contact with GCG in Sydney for the turbo, Powerflow injection for the pump and injectors and Just Jap for an intercooler. Im using similar equipment in my RB25DET (550cc injectors, 040 pump, GT30 / 71R and JJR front mount) and my car makes 230rwkw and 550nm at 18psi, very conservative AFR and it has bugger all lag.

Roo Posted December 10, 2007 Author Share Posted December 10, 2007 Great, thanks for the info For the moment its on hold due to a matter of funds, but I will definitely take your advice into consideration. I have been considering dropping the whole lot into an R32, but again this is more likely to happen later rather than sooner, once I finish my apprenticeship BTW, anyone know what a good R32 rolling shell might be worth, just out of curiosity?
