are you still running the stock fuel pump they can cause all sorts of trouble when there on the way out may want to check fuel pressure particulary when its idling funny see if the pressure is jumping all over the place.... either way an ungraded fuel pump is a smart mod to do as well.

the stock ecus on 33's are very tempremental things they dont like being taken outside much past stock without causing some sort of issues sort out your plugs first see what happens may wanna check the ignitor module to make sure it dont have dirty connections and such. failing that if it doesnt feel like a missfire look into ecus and piggybacks to tune it out.. cheap way to check if it is plugs is buy the copper ones as a test set they are about $3 each quick easy way to eliminate any plug issues BCPR7ES gapped to .8 is what i use no probs so far.

does it pop and fart around or just fall in a hole then pull itself out if it pops and farts regap the plugs to .8mm see how it goes factory gap is 1mm way to big for anything other than stock, what plugs are you using by the way? if it feels like it falls in a big hole then pulls itself, with the mods you have and the especially if your running more boost with stock ECU i would put money on rich and retard. time for aftermarket mangement or a piggyback like SAFC do a search on thses there are heaps of old post with others having your problem....

anyone got one

after an AVCR display screen the bit that usually sits on your dash dont need any other parts just the screen thanks

hi just received my avcr this afternoon was bought from another SAU member wired it up then went to check it and the screen does not work the little orange lights for the buttons light up but no screen. i have wired up several of these and SAFC's before have the two earths in the correct places all wiring was double and triple checked its all perfect as per the APEXI instructions is there anything that could stuff with it or is it a dud, it does look used because it is but what are the chances that i have been sold a dud any ideas would be greatly appreciated.

where abouts are you so i can pick up the turbo thanks

just stock ones will be fine

hi ill take that vg30 turbo off your hands if it is still for sale

one thing you can try is take the wastegate arm off the flapper and wire open the wastegate you should make no boost if it does create boost then the wastegate hole is to small. if so whip the turbo off and port out the wastegate hole either yourself if your feel confident to do so, or get some one to do it for for you. also take off the lever/arm off the flapper with the dump pipe on and operate it by hand see if it catches anywhere. BATMBL dump pipes in my opinion are the bomb but are designed for a stock turbo your hks one although is made to be the same may have a suttle difference in the flapper i dare say it may actually be larger so check what i said above and make sure it doesnt foul on the dump simple fix for that is to get out the die grinder. if you have alook at my old posts ive gone through all this before so you may find some help in there

what sort of dump pipe do you have if its an ebay special i can tell you that its most likely fouling on your wastegate flapper and not allowing it to open i had this happen to me either way whip the dump pipe off and see if can see any marks were the flapper may be hitting. as well check the usuals splits in hoses and that they are connected properly and maybe try wacking on the rb20 actuator as the 25 one may just be stuffed. i have also heard of people using a bashed out cat which actually creates more of a a restriction as it causes alot of turbulance in the hollow housing. i had this same problem but in the end it turned out i had a lot of none standard 25 gear in my engine which created alot more gas to try and get rid of thorugh a stock turbo

im after rb25 crank and rods and also Apexi AVCR anyone got these lying around thanks

hey mate you in brisbane im interested in the turbo and would you sell the 26 crank and rods seperate if so what condition they in. thanks scott

ive got a 25 in my s13 can really speak for the 1js and 2js havent dealt with them much for a pretty a stock motor with a couple of the usual bolt ons my car is a whole lot of fun to drive nice amount of torque and power in a reasinably light car. other thing you may whant to consider is if you wanna keep A/C its very easy to bolt back in instead tryin to fit up toyota gear ive found alot of stuff is interchangable from 32s and 33s which makes life alot easier

SOLD PENDING PAYMENT....... for sale 1 rb25det forward facing plenum, it is just the standard one which has beed cut and welded looks neat for what it is. is only the top half and is pretty bare no acc valve or anything like that whats in the pics is what you get. looking for something around $160ish am in brisbane south side 0403530367 scott

whip the covers off the front and wind the engine over and see if your marks are still lined up, just to rule out any chance you have the belt out a tooth

i have a set of hks cams for a series one laying around and am looking at buying a 33 in the near future so am wondering if they could be fitted to a series 2 engine if i ended up buying a series 2 33

quick question what the difference between rb25det series 1 and 2 cams are they interchangable

Engine/Car:13 rb25 with rb26 crank rods pistons, hi flow and a few other goodies Type of failure:worn main bearings and totally rooted number 6 big end killed the crank and one rod Factors influencing the failure:good old gtr crank snout failure, ending up just turning in the oil pump an not pumping oil State of tune of the engine:tuned safc Suspension and tyres:stockish Oil used and service interval:shell, mobil 1 tried several oils changed every 2000 or so General comments:pulled engine down found the flats on the crank snout starting to round and also on the flats of the oil pump drive hence the poor oil supply especially all the back at number six

cmon its late and ive been pulling my motor apart since 5 this arvo number six big end bearing is waffer thin. thanks champ

ive searched im obviously alittle blind tonight will keep looking thanks

is there any difference between the r32 rb26 crank and the r33 rb26 crank, are they pretty much interchangable when putting them into a rb25 block.

im looking for an rb26 crank anyone got a spare lying around, would like it to be in good nic too thanks all

thanks champ you just made me a very happy man
