who ever you buy it from dont tell them if you are putting bigger turbo's or aftermarket anything on it or your warranty will be void.
just tell them you need it as a stock replacement for your GTR.
yes u can, aslong as its not 4wheel drive.
take the filler plug out of the side of the gearbox and fill the oil through the gearstick hole and watch for when the oil dribbles out of the filler hole on the side,
try to have the car level when filling it up.
rewiring the fuel pump is easy with R33's or any car that has a battery in the boot. just need a relay and and decent fuse holder with some good thick wire, plenty of DIY info about it.
if you do the rewire and your worried about the tune i can throw my wideband on it and we will go for a little run and check the AFR's
When it drops a cylinder 1 by 1 disconnect the coil packs till u diagnose which cylinder is misfiring. Then turn off and swap that coilpack with the next one. Restart and recheck if the same cylinder is misfiring or if the same coilpack is misfiring.
of course its more accurate but its not practical,
if i have to tune my GTR then throw another GTR on the rollers, then the next day do a silvia etc its just not practical to have a probe setup, dont get me wrong it would be good to have the probes.
i just got a 1000degree infrared thermometer, i need it for when i tune cars not just mine, mine is a pain in the butt cause with the stock position twin turbo setup on my GTR i cant gain access to the manifold or dump pipes easily,
but on silvia's etc its going to be useful to check individual runner temps,
my old tuner set my stock AFMs like above on my old GTR and it made 419KW
if my AFM's max out on my current GTR im gonna try this, much cheaper,
why doesnt everyone do this instead of buying Z32's? i understand the sizing difference of the body but surely the sizing of the stock AFM's could handle pretty big power.
and also the added weight.
do you have a dyno sheet with your current setup?
you could try adjustable cam gears to bring the power on earlier although if your max torque is at 4400RPM 520NM thats already pretty early, my RB26 has max torque around 5500
my Bad, sorry, i mis read the boost.
just read the build you went all out, well done, so are the turboes definately -5's? you will need atleast 20 psi to see some big numbers,
What compression did you build the motor too?
make sure you drain the gearbox oil. and be prepared to still make a mess when you pull it out, it all runs out the extension housing where the tailshaft was
