Hey guy need some help I've got a t28 turbo off a skyline on my calais. I no what your all gunna say too small, won't run, run out of puff, buy something bigger but this is what i got so work with me. The prob is it won't hit full boost till 4,000 rpm. comes on like a shower of **** when it does though. could it have a boost leak somewhere I'm running a front mount too by the way. I don't under stand it i would have thought it would be on boost at 2,000 and stop pulling about 5,000 please help it's giving me the poo's.

id piss it off and get a decent t3 high flow

skylines have T3s and if its from an R33 then its bigger than a VLT

Do you have an exhaust leak? Is the spring holding the wastegate fully shut?

thanks for the ideas i did see that one of the fins on the exhast side is missing could that be a cause

yes that is gonna be your problem. new turbo is needed by the sounds of it, and just for the record a r33 turbo is smaller than a vl T3. cheers

i wanted to get the largest standard nissan turbo rebuilt and hiflowed. i thought it was the VG30DET but i rang GCG im pretty sure and emailed the tech guy at HPI and both said RB25DET was the biggest which suprised me being bigger than both 3 litres.

vg30dett is a t25, they are shhhh1t trbos and very weak

.....I'm sure you can find a standard T3 somewhere, f*ck it's not that expensive. Too many people on this f*cking forum screwing around with sh*t that sucks and is "cheap" or they "just happen to have or were given for free". Do it right!

if you need a new blade on the turbo, a milo tin lid and a stanley knife work ok for a temporary fix, strengthen it with heaps of solder.

milo lid hey got a couple lying around might try it thanks lol ****

rb25det turbos are definately not bigger than t3's lol. And cant believe you put a turbo on with a missing fin. Its just not gonna work mate new turbo is what you need.

Its just not gonna work mate new turbo is what you need. The wheels are similar but the exhaust housing are definately not the same, i think rb25 is a .58 vs .63 for VL a VL or rb25neo/VG30DET ball bearing T3 is the best to highflow the latter having the wastegate in the housing which is a bonus
