or buy yourself a rb25det half cut i did for my vl however i underestimated how much it would cost me and it ended up costing me close to 8-10gs

if you turbo a r31 skyline( stock rb30) you will need to rebuild whole motor no point just slapping on a decomp plate and turbo kit cause it wont hold much boost at all. if you want information on all of it go to calaisturbo.com.au they will tell you everything yopu need to know about the rb30

Like luvpsi said, there are 'cheap and easy' ways to go about it but they will definitely cost you the better part of 10 grand.

Get a manual one then buy a skyline halfcut and bolt it all in... is the easiest way to go by far. Even if its an RB20, it sounds like all you want is a turbo.

Be it myself, I would need a good reason to have a R31 to begin with lol... But then if it was what I wanted, I would buy the R33 or R34 half cut, then conjur up a RB2530DET hybrid by following instructions well documented on this site, then get a full exhaust, fmic, fuel pump, good injectors, good afm, tunable ecu and a 500ish HP turbo (id be willing to try an ATR43G3 on this budget project) and get it all together.

With epic torque I would saaayyy.... thats the better part of 15 grand though.

as all these guys have said, youll spend 10k doing it properly, maybe a few grand initially doing it on the cheap then when stuff breaks and you end up doing it properly it will all add up.

Just buy one already turbo'd it will be cheaper trust me, just ask anyone who has already done it. You need tyres, suspension, clutch, fuel pump, tuning etc, these are all the added extras on top of turboing the motor assuming it doesn't explode.

Firstly. f**k all the haters above...

Secondly. Easy

buy VL turbo aka 270cc hose tail injectors or any other similar type of hosetail injector.

Buy turbo manifold. Ebay used to be a good place but stock is low. Try for a 2nd hand stock cast iorn vl turbo manifold.

Buy a turbo. An rb25det turbo ia a good start for about 180rwkw

contact nistune for a custom remap. Around $100 exc postage

Custom oil+water lines are $100-150 on ebay

now. Either take the lot to a resonable performance garage and have them fit it and have the piping+dump pipe fabricated. This will cost around $1000

Or do it yourself and save around $700 labour but tou will need to pay for random pipe and joiners and also pay for the exaghust to be made.

I turboed an automatic TI r31 for around $1500 total using a KKR480 turbo $600 and mates rates on the dump pipe

    • Will have a look at that. I cant see any leaks 
    • Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.
    • Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
    • Hi Everyone I am from West Pennant Hills in NSW. Been too busy until recently to attend to my RB25DET Series 2 engine until recently. I am planning to stick it into the S15 shell at this stage, unless a nice SR20DET turns up... For now, i am going to try and get the RB25 running and working well then decide what gearbox to use. My preference is to retain the SR20DET  6 speed gearbox and tail shaft to retain as much and least modifications as i can avoid. I am an old guy and won't be doing any heavy drifting so i don't need a bullet proof gearbox Does anyone have experience with starting the RB on a stand? I got everything setup as much as I can with the info i can find... endless searching and videos on Youtube I would be great to get some pointers Cheers Songo
    • Hey all, Recently have had my s1 r33 gtr serviced and noticed my coolant reservoir was topped up to the max line. Took the car out for 1 yesterday and noticed today the reservoir is completely empty.  Any ideas? Radiator is full
