How hard to change turbo?

[JH32]

How hard is it to change the standard RB20 turbo for a VG30 item?

Is it a difficult job?

What's involved?

Cheers!

[skyr31]

I had it done on my rb20, it bolts straight on, the only thing that had to be done was rotate the housing slightly, it only took a couple of hours! Good luck !

Same goes to putting turbo on RB25DE! How hard is it?

jimi: easy man, we can do it one afternoon. just need a couple of cans of WD40, those manifold bolts are bitches to get off!!

joe: hard, you need new manifold, turbo, intake piping, will kill your gearbox and clutch after a while cos of extra power. just buy a turbo'ed car

:uh-huh:

Keep us updated on how you go jimih, might be looking at doing the same thing (or maybe a late model rb25 turbo) in a few months.

I am also very interested in seeing if oil feeds and other anciliaries bolt back on without a hassle. So basically on an RB20 all you have to do is buy new gaskets and rotate the housing? Sounds too simple to be true. I have access to a VG30 item and I'm very interested to hear the how to and any problems anyone has encountered, before I roll my wallet out and my sleeves up.

Waiting patiently

p.s also safe boost level on VG30 snail with stock R32 apart from cat-back and bleed valve. thanks

[adam 32]

thats the other thing i was gunah say jimi

theres a few things u might wonah do before bolting on the turbo... a good pod filter/panel filter, boost guage, possibly intercooler. id say get a boost guage, pod filter, boost the std turbo then wait til uve got a FMIC and fuel pump to take full advantage of the VG30...

[MrMayhem]

VG bolts diretly onto a HR31 turbo setup

the 25 bolts directly to the R32 RB20

your going to need to use flexable feed lines to put teh vg on a R32 RB20

[skylark]

Oil feed lines? Do I need new fittings/ banjos? Sizes if you have them on fittings and/or hose, I would be very appreciative. Rather than pull it all apart and then find out, reassemble then attempt again.

Any info would be received with open arms.

heheh mmmm looks like I'm gonna need to do some things before leaping into this hehehe

well I was gonna fit the bleed valve and boost guage after exams and then hopefully find a FMIC somewhere too.

guess I'll just wait a little while for this turbo.

R U serious Joe?

RB25DE and DET arent the same engine really as such..

The DET has stronger internals and lower compresion, totally different exhaust manifold setup to just name a few...

It would be easier to sell yours and buy a turbo like you should ov done to start with rice boy!

JimiH as in turbo upgrades the T3 vg30 is not a hard upgrade compared to alot of others, altho u have to check oil and water lines match up and dump pipe is the same bolt pattern as the guys have already mentioned..

T3 wheels are a fair bit bigger than the standard T25 ya cant go wrong!

[JH32]

I'm now thinking maybe I should go for something a little bigger?

What do you reckon?

[adam 32]

well it depends on how much power you want to make and how much lag you want to deal with!

the VG30 should make 280-300rwhp. is that enough for u?

[JH32]

Shit!

Didn't know it could handle up to 300rwhp!

Yeah that'll be fine for me!!

[macka]

And that comes from the LagMasterAdam32

2 choices that u can do.

Hi flow your existing turbo and no other mods

or Buy a T3 and rebuild it then posible mounting issues because T3s come from VL Turbos and 300zxs or the like.

The T25 has to go

You can run a modified turbo with no other mods such as FMIC and Retuned fuel curve but u wont get much benifit until these are both done + u will be running minimal boos without a fmic if u whacked on da turb first!

300rwhp is is really maxing the VG30 out!!

Go for sumthing bigger where u wont have to have it runnin at its peak.

I agree

Youll be running up towards the 18psi mark to get that

[MrMayhem]

so 18psi with a vg30 turbo makes 300rwhp on a rb20

is this correct?
