hey guys just a question ive got a few mods done at the moment,i was just wondering who remaps standard r32 ecu's i will be gettindg an aftermarket computer round the end of the year when i have finished building a rb24 the only reason i want to remap the standard computer is that i want to be able to drive my setup as it is at the moment and need to save for other more important things like getting it engineered blusliped and registered so im just after a cheaper solution to the prob for now but i still want to make some desent horsepower till then atleast i hope you all understand what i mean ive had this car for 12 months and im getting desperate i need to drive it so bad mods are: 1..bigger turbo unknown size bigger than a T4 apparantly? only slightly i can post pics if ppl want 2..custom made high mount turbo manifold 3..externall gate with 12psi spring 4..front mount 5..3inch turbo back 6..GTR pump 7..adjustable fuel pressure reg 8..i think thats bout it in about 6 to 8 months i hope to have a RB24 in,ported polished head 3 cut oversized valves and heavy springs, cams, rb26 injectors possibly bosch ignighters and a wolf 3d ver 4 fingers crossed its a huge list but thats why i dont want a after market computer straight away i just want to drive what i have know so if anyone knows who chips or maps or whatever you do to standard R32 ECU's in between sydney and coffs harbouri live 1 hour north of Newcastle any help will be aapreciated thanks matt

its been a long time between drinks at the moment i have finally driven the car ....whoo hoo but... smashed it :Oops: well not my fault it had been at the auto elects for three months forgot the bonnt latch was not on the car and yep you guessed it on the way home doing 50 after boosting only 1 min earlier the wind picked up and flipped the bonnet smashed the screen and roof well 1500 later all good again anyway engine came apart found that the head gasket was all good just recently changed head sent for check came back 100% could not be better so must be the bottom end pulled the rest of engine out of car pulled bottom end apart hping all i needed was a set of rings nope looks like that when the previuos owner did the head gasket they left it to late water had pitted the bores thats why i was losing compression and had a broken ring in three so a new bolt in replacement is being sourced at the moment matt

all turbos have some sort of play this play dissapears when the turbo is full of oil ie.... the shaft sorta floats on the oil although i would have someone look at the seals in case they are cooked hope this helps

i had same prob but much more severe 5 cyls were at 115psi instead of 160psi and cyl #3 was at bout 55psi chacked like 6 times head came off head gasket fine bottom end looked like just rebuilt head sent off for check came back 100% looks like rings are craped

ok here they are torque specks for manifold studs or torque settings whatever you want to call them are as follows 18 - 24 N-m (1.8 - 2.4kg-m, 13 - 17 ft-lb)

i mean if you having that much trouble tell me how many you need ill send you some for nothing thats if you cant get them of course dont exploit my generosity!!!!!

thank god someone listened to me i mean this should not be such a big deal geno8r you just need to go to a knowledgable parts store and tell them what i have told u if they dont know what you are talking bout go round the corner these people should not be behind any counter simple as that

like i said it dont have to be nissan i got these from repco M12 x 1.25 manifold studs ask them to check on the thread tester must be M12 x 1.25

hey guys you dont have to go genuinne nissan just take the part of the thread that is left to any parts shop and they can match it i took just one bolt to REPCO and they had them in stock you dont need a part number im pretty sure like 99% sure that they are M10 x 1.25 head studs or manifold studs what ever you want to call them and i tried to find my torque settings but cant help there sorry

hey guys i just did this the other day broke all but three of them i did not have the tools to take out the others was told that if i was taking out some i should replace all of them but some were stuck in the head and didnt brake was told i need a special tool that removes studs its not a ezi out kit but it was big and went over the stud wound it opposite direction while grabing the stud any way i tried the easy out on the others but did not want to brake the others that would not work was told to spray inox on them for the next three days and so morn and night i sprayed them and they came out so damn easy it was not funny as soon as it broke free from the head i could finger screw them out the spray makes a hell of a diff trust me

thanks to slide i have at least what my turbo is from a 98 GMC/ chev pick up a 6.5l heap off yank shit oh well it looks beeter in my engine bay i think so any way http://www.turbodriven.com/en/productsearch/index.asp

thanks guys link to BW helps didnt even know they had a site thanks heaps as for lag the car has been built for the last 8 months first drive the other day and the lag was.... well.... how do u say ....BIG!!! boost hit 6 psi at 4000 didnt even make gate at 10psi and just wanted to break out the car has ****ed compression like 50 psi on cyl 3 and 115 on the rest so the head is off at tthe moment actually the day i drove it i took it off getting the head looked at the bottom end rebuilt id say a bout 2000k ago but the car has not been an the rd for at least a year and half cuz of crash i bought and fixed and took it from standard to this so looking forwrd to seeing how it really goes

someone must know???

oh well if it only lasts that long it will do ill prob have the stupid head off again in bout 6 months anyway so ill do it with some better shit then and thanks for the info on the gate i dont have a boost controller so i guess it didnt even cross my mind thanks anyway man!

yeah here is a pic of the pack what did you use?? i have a feeling this will prob do the same it was only cheap.

hey guys just a question what are the two nipples on the top off my wastegate? what do they do? where do i connect them to? and are they both needed??? here is a pic

hey guys just wondering if anyone knows what size this turbo is i have no idea i know it shares the same flange as a t3 but the front apparantley is bigger than t4??? but i dont know here are some pics any info would be great thanks guys

also what is the usual cost of a full rebuild i can get forged pistons for bout 800 dont know if that includes rings what else do i need and approx cost me and a mech friend can assemble but what are the usuall costs of what ever else i need to do?????
