Need Help Bolting My Turbo Back On.

[jahn-15]

Ok so i bought the car with the big garrett taken off and it had a aftermarket exhaust manifold and tial 38mm wastegate bolted on. Took that off and was going to put stock manifold back on with stock turbo but realized i didnt have any water or oil lines or gaskets or copper washers etc so ive ordered these but theres a few mani studs missing. after somone that can help replace mani studs and bolt turbo back on. Or a workshop etc that u guys have dealt with?

Can u put some pics up of what your talking about will help.

If u need exhaust manifold studs look at justjap.com they have them.

best way to put them in is get two nuts thread them on, then try and do one up and the other undone, this binds them together so you can finsih puting the bolt in. once done undo the nuts in the opersite way as to doing them up.

Not hard just need some tools.

thier is a few DIY threads look for RB25 turbo upgrade on R32 GTST in the DIY section.

Alright thanks heaps ive just ordered one of those rb25 turbos anyway so the thread should help witb any differences. Also the car has been rebuilt and has a 3"exhaust, 3"dump, hi flow cat, front mount, earth kit, microtech lt-12s, soon to have series two rb25 turbo, brass button clutch,

To make around 200rwkw would i need yellow jacket coils, injectors, fuel pump, ?? My mate reckons ill need a fuel pressure regulator?

But what gets me is it previously made 238.3 rwkw with the gt 3540 "dont ask me why they had this turbo on a rb 20 lol" so maybe i wouldnt need any thing else to make 200 to 210 kw??

um.......why are you removing the turbo anyway, sound better than a stock rb25 turbo???

as long as your coil packs work ok, don't bother buying new ones for under 300rwkw, not needed

fuul pressure regulators are over rated, if you have injectors large enough, no need. If you are after the last 10kw from your stock injectors, the fuel pressure reg could be of use, otherwise don't bother,

Aww ok thanks for that, i bought the car minus gt3540 but it came with the stock turbo not bolted on. The rb25 series two turbo will do for now just bought a rb25 wiring loom and am looking for a rb25det in the near future.

But a friend has a rb30 turbo motor that he wants out of his yard for the lowley price of a carton so might look at rb30det also!

Rb20 head wont fit on a rb30 mate, you'll need to find yourself a 25 head for that mate.

What ECU was it running with the old turbo?

[jahn-15]

Yeah i no another mate has a complete rb25det also so might grab that off him, it was with the microtech lt-12s

Your mate is an idiot and doesn't even know what a fuel pressure regulator does.

[jahn-15]

Yeah i was thinking i didnt need one after reading martin donnons 15 not haves in performance imports issue 132, but this particular mate owns a 5 ltr vp commodore so i thought he of all people would no lol i tryed reciting what martin wrote but couldnt remember lol

[XRATED]

To be honest, don't get too carried away with engine swaps etc..

If you don't have the skills/knowledge or tools to put a stock turbo back on, your not going to be able to complete an engine swap.

Get the turbo, manifold, dump pipe, exhust and cooler pipe work sorted out- get the ecu re-tuned. Then just drive it for a while! Spend some money on brakes and suspension before you go getting into engine swaps.

[jahn-15]

Yeah im gunna tackle it tho can only try. Ive got tools i hire a shipping container and its on my uncles property he owns every tool you can imagine ( earth moving & truck company ) so thats no drama.

I agree i wouldnt tackle a engine swap until im more confident and experienced and might wait till the rb20 gives out anyway.

The turbo should be here today or tommorow then i can take it to this shop in newy called pit crew and get my braided oil & water lines made up.

I have a high mount manifold with a tial 38mm wastegate but i didnt no if id be worth putting the rb25 turbo on that or stock manifold? Id have to get longer oil lines made ?

The dump is ok unless i wanna make a screamer!

The exhaust is some custom made 3" mandrel bent with a high flow cat. But i liked the sound of the blitz nur spec on my last 32.

The intercooler and hard pipeing kit has been taken off and am currently spraying non gloss black dont want to attract any unnecessary attention.

I definitely wanna get it tuned asap and wanna get cold start sorted.

Atm there just stock brakes painted blue :-P will look into something when i hit eastern creek up.

The suspension consists of nismo adjustable shocks, matched to some sort of red springs dare say pedders, and kkr castor rods, wanna lock out hicas and chuck adjustable everything in it. My last 32 had kei office coilovers i really liked those. Also will chuck in my nismo 2 way at some stage.

Yep

Found your problem

FPR's are only needed if your injectors are maxed out and your to tight to buy new ones, I can understand possibly if your stock FPR breaks and you want to just replace with an aftermarket one. But end of the day stock FPR and correct injectors are the best way to go

[jahn-15]

Yah if it aint broke dont replace it! Or maxed out haha

[R TUNE]

Didnt read threw rest of the post but for the power you are planing you should get a upgraded fuel pump.

i brought a walbro 500hp pump from www.horsepowerinabox.com for $160. Bosh 040 is also good just a tad more exspencive but can handle higer HP (rated to 600hp)

[jahn-15]

Yeah i wanna see if i have a stock one or aftermarket.

My new rb25 series two turbo turned up today its physically bigger than the stock rb20 turbs so thats a good sign hopefully it will handle 14 psi

[jahn-15]

Well the turbo is all bolted on etc but it is running rough heard it needs some nipple welded in to the intake pipe? Could this be the cause? Or maybe afm or a sensor of some kind not sure

[89CAL]

Did you leave a hose disconnected? (vac line)

Also run 12psi not 14 or you could blow the turbo up

[jahn-15]

Probably ill have to check it out need it going asap coz my daily got sideswiped and is now a right off and no number was left
