RB30 reconditioned to an RB30ET.....

[Scotchy88]

I have a 1990 GQ with an 3B30E (also runs on gas) and want to recondition and turbo it...

What are your thoughts??

[Scotchy88]

Was just informed that there is no turbo kit available for the RB30 and the best thing to do is put a VL engine in and build it up from there.... answered my own question lol but for anyone who was interested...

[YNOT]

What part of Brisbane are you in?
Reco the RB30 bottom end and put an RB25DET top end and turbo on it.

or just put a rb26dett in it, stuff frigging around with old school RB30's

Im from the northside, cheers fellas i'll look into.

I have the RB30et in mine, i like it, but i'm going to go a VQ30dett:wink:

This is quite an easy and cheapish conversion, and the specs of the stock VQ are only JUST lower than a LS1, but are a LOT better than an RB30et:bananarock:

Mind you a well sorted RB30et has enough power to keep up with most 4WD's:bigthumbup:

VQ30DETT-nice! How hard is it to adapt this to the Patrol driveline?
Will it be a custom twin turbo set up, VQ30DETT was only used in Nissan race cars?

It is pretty easy as far as i've been told, all Nissan not a single bulldust adapter in sight:049:

And there is 1 too may T's in there it should be VQ30det:redface:, but you never do know what's around the corner:049:

Even with one turbo it's still a nice engine - post '98 VQ30DET 210kw @6000rpm, 386Nm @3600rpm on 7 psi boost.

Its apparently quite easy to turbo the RB30 in the GQ's by using parts out of a VL turbo. All the injections gear is pretty much a straight swap, as is the turbo gear. Gq block already has the oil and water lines in the block, good to go.

Im planning on doing a turbo conversion in the next six months or so.

Yeah but from what I've heard they are an a$$hole engine to work on.

Nar I've worked on a lot worse.............. Like all engines thay have there good & bod points but the biggest thing is dealing with the height & reach you need when working on a Patrol so when you get used to that its not to bad at all.

[YNOT]

I've never worked on a VQ motor, but in a big engine bay like the Patrols have it should be a lot easier to work on than say a Skyline that had the engine bay built around the motor.

I thought the VQ's were in the 300zx's? Along with a maxima I think

[YNOT]

300ZX's had the older cast iron block VG30. Later Maxima's did get the VQ30, earlies still had the VG30.

Do you plan to post a blow-by-blow (pun intended) of the process here. I for one (and perhaps the only one) would be chuffed if you do.

He hasn't been on the forum since the middle of October so I doubt it.

Sure. I thought it might be worth a try. Just in case...
