Steg33

pssiii, i've got an R33 SII turbo coming off my car through the week, it has no shaft play because i only bought it 2 months ago before my motor went bang. Selling due to motor rebuild and new bigger turbo upgrade. I'm about to post it in for sale section for $500 but would be willing to sell and send to bris for $500. Send me a PM if you want more info

Sweetr33, as RedDrifter said, that "fluttering" is the air going back into the turbo. A lot of the VLs sound like this because they didn't come out with BOVs. More boost=more fluttering and that's not real good for your turbo (turbo goes from high rpm to low rpm as the air resonates back towards your turbo). The whole point of a BOV is to prevent this so the pressure is taken off you turbo!! I wouldn't disconect the BOV for real long if you're boosted!

Not a problem Whatsisname, i was having some trouble reading the Japanese. Thanks

Xplodeskyline, MCCR is the Melbourne Car Cruise Registry. A fairly big club of all kinds of cars. When out and about there's always a few d**kheads causin trouble. Bit of a cop magnet. If too many people want to change the date because of this, then soon after would be good otherwise it will never happen.

Sydneykid, sounds like a couple of good ideas there. Do the Tomoei poncams make the car any rougher to drive normally because i'll still be doing a fair few k's in the car and don't want it to be too bad if i get into traffic? How much will it actually bulk up my power curve? There's only about $600 between going for a highflow or GT2540®/GT2835® so i'd feel a bit more confident with a new one of the second choices. Like everyone else, i'd like the boost not to come on too late, but make the power safely and easily. I'm thinking RS500's idea of the GT30 might be a bit big, and with one of the two samller ones i shouldn't have to change my dump pipe (split). Thanks again so far guys. It's been a lot of help

Steve, it should be possible to get more power out of those 440cc injectors with a fuel pressure regulator or larger pump shouldn't it?

Nismoid and Ben, i've still got the factory ECU but it's been reburnt so the fuel settings shouldn't be too bad. Can't usually run bigger injectors without some sort of remapping. Current is reduced so they don't pulse so hard. My car does run a little rich but not to the extent that oversized injectors on a stock ECU would be. The car was from Japan with a heap of mods. The motor's just s**t itself because there must have been a huge turbo on it before they sold it (was a smaller than stock turbo when i got it, R31 i think). Going in for the rebuild at the moment.

28th still sounds like a good idea regardless of other cruises on that day. SKYLINE people will turn up to a SKYLINE/sports cruise. If we have to we can always go the backway from Apollo Bay to Geelong through the hills and the other half the GOR or vice versa. There's a bit of fun either way. Camping also sounds like a good idea as long as it's set a fair way in advance. All ideas are sounding good, so assuming my car's finished and back on the road by then, count me in!!! Pick a date and i'm there!

Sounds good Benm. I guess it would be easier for people to comment if i give all my mods like you did and anyone can let me know what they think. CURRENT ENGINE PARTS: AVC-R SII R33 turbo HKS pod intake Split dump pipe Blitz 3" cat back Denso 550cc injectors FMIC Apexi Hybrid Bosch fuel pump (not sure what size but whines it's head off constantly) Re burnt ECU Blown Piston!!!!!!!!!!!!!! MODS IN PROCESS: 3" front pipe and highflow cat Full rebuild Forged pistons Metal head gasget Port, polished head Angle cut valves Machined block Shot peened rods Power FC (get rid of stock AFM) Possibly an exhaust cam pulley That's my set up at the moment. Now i just need a turbo that will give me some kick and is still streetable and reliable. 250rwkw would be ideal but open to comments for more power possibly. Should i run a highflow combination or GT2530,GT2835 etc?

Sydneykid, the mods have already been done (all Japanese before importing). The only things still to come are the engine rebuild, PFC and turbo upgrade/highflow. Unfortunately the motor is getting rebuilt only because i've got a heap of smoke bellowing out the back and low compression in cylinder 5. I would have avoided the rebuild if the oil burning problem didn't come up (was still drivable until yesterday when it started to really spit smoke). The forgies, etc, are just getting done while the motor's out, for a piece of mind and it still gives me the option for more power later. Also want to know if my current FMIC (Apexi Hybrid) is going to be efficient or big enough if i'm getting 250rwkw?

Thanks Merli. That's the kind of chart i was looking for! I might look at something like the GT2835. Anyone had any experience with a GT2835 compared to a GT2530? Wondering how early each one comes onto boost or if they are direct bolt ons to the standard RB25DET exhaust manifold?

Just wondering if anyone has any or knows of any good sites that have comparison sheets for power v's response for different turbos? I know everyone asks about what turbo to get but there's no actual comparison charts on the search. Has anyone got any recommendations for a turbo to get me up to around 250rwkw? I'm still looking for it to be streetable. I'm asking a bit but any info would help. My motor (RB25DET) is going in for a full rebuild with forgies, head flowed and metal gasket, etc. I've already got all the basics done, exhaust, intake, 550cc injectors, AVCR, bosch fuel pump and will be purchasing a PFC to run it all. Do i need anything else before i can reach this power figure?

Thanks for the reply boli, i ended up finding that site just after i posted this. I'm guessing the ND stands for Nippon Denso and they must be the same make as the sard ones. The only thing is, i've got an RB25DET and they're stated for the SR20DET. I'm assuming my fuel rail takes the same injectors as the SR20DET? Has anyone else heard of these Denso 550cc injectors or can confirm that they are 550cc? I've got my motor going in for a rebuild and was hoping i wouldn't have to upgrade when i put a bigger turbo on (GT2835 or GT3040).

Sorry, small mistake. The part number's 195500-2240 Only one 9

G'day guys. Just wondering if anyone can tell me what sized injectors i've got on my 95' R33. I've had the car for a few months and am still finding new things under the bonnet. The injectors are Denso, part number 1995500-2240 and have a pink head on them. Any idea how many cc's are these?? I've also got a mate that wants to know what colour stock R33 injectors are (his are purple) and even a part number if possible? Any help's appreciated. Thanks
