Changing Turbos

[335]

Hello

I just took a RB 25 turbo off for my first time, of a junked R33. It wasn't hard. Most of the piping was off, so it was easy. I took off the afm tube, the turbo. I had problems with some of the line bolts, mainly the water line(the one that goes to the back of the engine. I just cut that one. The other ones were not too hard just hard to get to as far as reaching. I spent 6 hours mostly because I did it outside and it was freezing. But the line bolts were what slowed me down.

I have the elbow and down pipe for the turbo. The pieces were kept on.

Any suggestions for when I put it back onto my car, a GTS-T R32? I have read the tutorial on the Project 32 website but wanted to make sure that there wasn't anything else I need to do when I put this on my car.

make sure you do the bolts up tight (turbo to manifold) and use locking tabs to prevent them from coming loose.

Try using some maniseal on the old turbo flange gasket it should hold fine.

i've done this a few times and its easier if you do up the water line that faces the block before you mount the turbo on the manifold.

I thought u cut the line on YOUR car for the water line!!

Re read it a few times.....phew

You'll be right, all in reverse order. Schweeet !

Keep your old actuator for the nice 10psi istead of 5.

You mean behind the engine where the back of the coil pack cover is?

Do I have to take off the manifold? I would really dont want to take off the manifold.

Oh the RB25 turbo I pulled out has a HKS aftermarket actuator on it. Should I keep that on or put the RB20 one on it?

[Birnie]

The HKS actuator might be set to 1bar (14.5 ? psi)

That's near breaking point of these turbos.

Better off using 10psi actuator and bleeding up to about 12psi.

if it's adjustable, keep the HKS one on and reduce the psi.

Either way, it's worth $100+ so keep it for later upgrades or sell it for some buckaroons

nah, dont take the manifold off. i mean, lower the turbo into place, then do up the water line banjo bolt that feeds the turbo, then mount it on the exhuast manifold. i find it easier to do it this way, easier to get a spanner of socket onto the bolt.

Oh I understand. Will try that way. Well now I have a choice, I can put the replacement RB20 turbo on to replace my blown RB20 turbo, or I can put the RB 25 turbo on. Only thing is I don't have a fmic on now and I don't have a piggy back computer to tune. So should I wait to put the RB25 turbo on until I have a fmic or is it ok to put on now and don't tune it?
