yeah it was preety much like that lol am not really pissed off its just it came at the wrong time i was always wanting to build an rb30 that can withstand a real punishment. maybe this is my time, SPOOL has got a preety good stuff that he sells. but finding a trusted builder in adel is a bit hard u hear stories of other people and it just makes u wonder thats y i do as much as i can, i am a car sparky but have a broad mechanical knowledge

yeah well they are supoused to be Je pistons, have shotpeened rods, all acl bearings, cometic multilayer head gasket, arp bolts, etc etc but honesly i dont believe a thing he said, my friend did inspect the engine before he put it in and it all looked that its been properly built, but d question is, did he put that engine in it or a standard rb30 cos he did have few rb30 blocks there will find out the hard when i pull engine apart

well guys today was the sad day for me i found out y i only ended up mking 320rwkw, ill start at the beginning My friend had the car i have now, he has had the engine built by SMD workshops in sydney and had it tuned there too only a run in tune though. i decided to buy the car of him and get it tuned there too, by the same guy using ems stinger ecu. becuase i was buying the car i had to ask him what was done to the engine what pistons rods other things he used. fuel system etc he said he had a 50mm greddy , external gate, greddy 850cc injectors, the whole ignition loom was changed blah blah blah, but little did he know that i have a bit of knowledge about cars unlike my unfortunate friend. when i went through the whole car i figured it was starting funny, noise was a bit different which put a question mark in my head, i realised its got nismo 555cc injectors, cheap $110 ebay external gate, ignition loom is original as its a ser 2 loom. and all the other bulshit he said was not right, i then ended up putting an external fuel set up surge tank 044 etc. nismo reg, with a real 850cc injectors, turbosmart 45mm pro gate etc etc he couldnt get it tuned it was overboosting then it was just runing gate spring pressure boost and all other dramas including timing which he said it was ok but when i checked it the base timing it was 30 degrees in advance, and i said just leave it cos the car was going on a truck to adelaide the next day. i ended up putting haltech plug in platinum series ecus and had it tuned everything finally fixed, new plugs etc etc everything done properly and ended up making only what i made. now to cut the story short i realised my oil catch can was filling up with oil it overfilled and spilled everywhere on my driveway and along the LH headlight i knew something was wrong so i did a compression test 1 cylinder was good 2nd, 3rd, 4th,it all went fine until i checked the cylinder pressure on 5th cylinder where i found only 60psi of cylinder pressure hmmm an engine that has done less then 5000km has gone ka boom suprisingly the car doesnt blow white smoke at all well who is to blame tuner, builder, myself???? but ill not point a finger at anyone cos shit does happen although i wouldnt trust the guy from SMD workshop in sydney thats all he made me realise that he talks a lot of bull crap, anyway the car still drives awesome with pleanty of power lol but i just know what i have to do, head off to figure out what went wrong other thing i found rear exhaust muffler the inside diameter is only 2.5inch

injectors sold

yeah i spoke to my tuner today he said at the same boost level (19psi) using e85 we should see somewhere within 350-360rwkw mark using the same fuel set up that i have now but bumping up the fuel pressure a bit. He highly recommended it. if i do decide e85 and 25psi boost then my future intensions are 1000cc injectors like you said earl braided fuel line and another 044 thanks all on your inputs

anyone??????????? lol

you just made me more depressed lol

ill speak to my tuner and see to bump up to 25 psi, other thing i am considering is running E85 like BMYHOE but will my fuel set up be enough for the E85????? the only think that sort of draws me back from e85 is the octane level does change from season to season, the blend falls down to about 70% -30% in colder seasons thoughts????

396rwkw using e85??? what boost if i may know

point well made, yep its exactly how u described it you do lose cylinder trapping efficiency at lowish revs and it does feel like a lil daggy down low and i probably would have made the same power with d 3076 using a bigger exhaust housing. Being a 3 L- it still is drivable but sometimes when you just want that lil extra pull at lower revs it just lacks it, but it doesnt bother me as much as i dont drive the car everyday, its just a weekend car. Power wise i wanted a bit more, maybe i shouldve done my homework a bit better but too late now, or just simply run 25psi i can still drop the head gasket thickness down a bit to bump up static CR, not sure what it is at the moment, have to find out. thank you for your imput

yep timing is 100% correct now, it was off before the tune but we corrected it as sometimes its a bit harder to get the timing positions right with the relocated idler/tensioner, all lines up ok now

way to big for street use and my liking

here is one of the dyno pulls, we ended up printing this one, the boost controller am using is elect. HDI, high boost is set at 20 it just drops off to about 19 but holds steady

hey i asked him already : but i sold it anyway injectors only left, suprised no one is interested

thanks bud ill have to book it in for another tune but i really dont feel like runing more than 25psi of boost i know the engine is built and all but i do want to keep the car for a bit longer and reliability is my no1

i didnt have cams when the engine was built, the builder told me that compression is going to be 8.5;1 so just going by what he said

yeah thats what i was thinking about, yeah more boost it will be i reckon lol

yeah its been checked with pressurised smoke machine there was a small leak but a new hose clamp fixed it

r33 gtst mods are built engine rb25/30 with neo head cr 8.5:1 cams are 270 9.11mm garrett gt3788 0.89 exhaust housing turbosmart hypergate 45mm wastegate haltech platinum pro plug in PE 850cc injectors nismo adj fuel reg 044 external/surge tank, 2x walbro internal pumps 3.5 catback, 3 inch dump, no cat trust intercooler 600x300x76mm thick 320rwkw @19psi power is a bit lower than some on here not sure why really would like to hit 350ish with these mods

Hi guys just wondering if this is sort of normal power figure for a built RB25/30 neo head car r33 gtst mods are built engine rb25/30 with neo head cr 8.5:1 cams are 270 9.11mm garrett gt3788 0.89 exhaust housing turbosmart hypergate 45mm wastegate haltech platinum pro plug in PE 850cc injectors nismo adj fuel reg 044 external/surge tank, 2x walbro internal pumps 3.5 catback, 3 inch dump, no cat trust intercooler 600x300x76mm thick now the question is that i only made 320rwkw on 19psi, i was expecting of somewhere of 350-370rwkw is this sort of normal power figure or should be a bit higher i had a look on forums here all dyno results and guys with my sort of mods are making in excess of 350ish with a gt35r any ideas thoughts much appreciated

hi guys here i have couple of things for sale EMS stinger 4424 came of a R33 gtst, will fit other cars but please do your research asking $400 - in good working order, there is a wire that has been soldered on to the plug as in picture NISMO side feed 555cc injectors to suit RB25det asking $500 there is a bit of plier markings on the injectors as i was pulling them out, they just wouldnt come out easy turbosmart plumback BOV with rb25det adapter to fit straight on where the original BOV goes can be used as atmospheric and is fully adjustable by hand, painted in black asking $80 located in adelaide can post at buyers expense please feel free to ask any questions or sms on 0415 466 726 for faster reply
