Turboing An Rb30

[R31Nismoid]

Well yes, the absolute cost generally isn't realised initially. But to answer the topic - it can be done and 'reasonably' easy.

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

LOL... What are you on about?

If you JUST want to bolt on your standard "VLt" kit, you can run 5psi no problems. There isn't an issue at all on a N/A motor.

You don't need decomp plates, you dont need to rebuild the motor etc etc.

If you add an intercooler then you can run 200rwkw without even a worry in the world. Countless people have done it now.

I bolted a turbo kit onto my x-trail, makes over 200awkw which is more than double standard power, motor and driveline has been perfectly fine for 50,000kms now... jussayin'...

decomp plate? do you still dress like this?

would a decomp plate still help you run more boost though? I know its f**ks with other things, but on the cheap could it work?

[JonnoHR31]

yer more boost for the same/tiny bit more power up top but less everywhere else

[Shane_954]

Stock n/a rb30 engine will handle 300rwkw all day if the tunes on the money.

The heads never been off my engine and still goes strong, makes 303rwkw@17psi on 98.

Only things changed inside engine are camshaft and springs.

Even the stock n/a camshaft is good for 250rwkw.

so tyres, clutch, intercooler. manual gearbox, all the pedals and crap, LSD diff, brakes etc are free?

you really do need all the above otherwise you might as well just buy one with it all for $5k

He didnt mention he wanted it to handle or slow down ^.^

That also is a lot of effort to go through to have a standard turbo in the car.

Only to no doubt want to upgrade later, in which case you would need to replace all the standard bits again anyway.

not alot of effort... its as much effort as replacing a turbo on a turbo car...

Drilling and tapping oil feeds and returns, water feeds etc

You do all that with a factory turbo car?

[luvpsi]

well that is what i was going to do for a while til i read plenty of threads on calaisturbo mentioning they couldnt handle much but hey do whatever you feel is right

[JonnoHR31]

31 rb30s have all the oil and water feeds and returns tapped with bungs in them, the standard vlt lines bolt straight up

Plenty of information on th 31club champ. I bought my coupe over 3 years ago non turbo, I done brakes, suspension, visual mods etc.. Then I bought a rb25det and it all started.. I'm only 1/3 of the way through getting it up to my power level goal but in total I would have spent over 20k, and currently in the process of a 3071, power fc, injectors, tune etc.. If I bought another coupe with some of the bits in it I could have been slot further.. But I have learnt slot as I have done everything apart from making the exhaust so it's a great learning curve.

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.

yer i know, im kind of put off the idea of turboing an old motor tho because i dont reckon it would cope to well with allll the extra power.

and the looks of a 31 are a bit offputting haha but its only 1200 bux and in pretty decent cond. but auto too

[luvpsi]

if i was you i would save a little extra cash and buy a r32 i beleive you can pick them up for around 5-8k

[zebra]

Also if you are not a Nissan fanatic, you could get a twin turbo Soarer for similar money.

I paid 7.5k for mine which was pretty mint.

[Shane_954]

Of course the engine will cope, its all in the tune.

[luvpsi]

yeah it should cope but not for long

My old slapper had around 220,000kms on it before the previous owner decided to throw a GT35, ecu and a few other things at it. He went easy on it, and only made 210kw to start with. This was about 7 years ago.

I then purchased the car, made a few changes and retuned it. Made 255kw and had a hard time every time it was driven. I ran 12.0 @ 117 on street tyres. This was 3 years ago.

Last year i slid a camshaft into it, changed valve springs, made a new dump pipe etc and retuned it again. Made 303kw, 680nm (17psi) on DD roller with mixtures fat at 11:1 to keep it alive. I ran 11.6 @ 122 in a manual 31 being fairly gentle with a 1.79 60.

Now the heads never been off this engine, so the gaskets nearly 23 years old and it doesnt push a drop into the catch can. Obviously i could make more power but its at its limit of reliabilty now, and i cant be bothered fixing it at the moment.

Id rather push an old rb30 thats been babied around by an old fella than a stock 25 thats had every dickhead and his boyfriend rape it.
