Rb26 Zorst Pipes

[7yphon]

I have been told they use a diffrent patten so I was wondering what I should do if I want to use the twins on the engine allready?

[N1GTR]

Um, what?

[bubba]

Do what now?

^_^ sorry was on a mates laptop and it started to get too me,

Im doing the 26/30 to my GTR and I have been told the twin turbo manafolds use a diffrent patten to the RB30 block.... I was wondering what other ppl have done to get around this?

[N1GTR]

I think you've been misinformed.

Mine fit fine. But, you have to add a small spacer to the dump pipes to make them fit. Nothing hard though

[7yphon]

I take it you just need to re stud the turbos for a longer bolt??

Also what about clarence in the engine bay? is there anything I need to move or watch out for?

My bottomend gave up on me and im am really wanting to do this conversion.

was thinking about S2 Block from a R31.

I would like to try and get the block to rev to around the same as the GTR 26 block but not too sure on what is needed to be done....

The engine from the R31 runs as it is now so eveything should be in somewhat of a working order.

so yer any help would be very cool

also I'm aiming at 400ish hp would like to get 450 if possable as thats a nice round figure.

If you're using a 26 head then your manifold bolt pattern hasn't changed..

It may be similar to the 25 head where I had to cut off a little bit of the bottom of the manifold as it clashes with the block.. is this what you were talking about?

[R32 Driver]

are we talking stock block or rebuilt with the good stuff?

i dont think a stock rb30 will rev like a 26

even when built people seem to take then to 7500-8000rpm

you also need an adapter plate to get the awd working

The exhaust manifolds bolt to the head mate, not the block, you are using an RB26 head so there is no change.

That what I thought but cheers.

Also im trying to decide as to what I will need for 450 or so HP do I need to put the good stuff in or will he stock block handle it??

I have seen ppl EG. RIPS do some nice HP figures on just the stock bottom end so they seem to handle a little bit of power

Mate there is two threads about rb30 conversions, i would recommend you read both of them before you even remotely consider doing this.

the RIPS gear does use stock parts. however, they do not just take a stock block and slap a head on it, there is lots of prep to the bottom end to get it to do what they want.

I have read both threads but it's a little hard to try and sort through would be better if we could combine all the answers into a page or something.

Anyway I now have the answers I was looking for cheers guys sorry if I wasted some time but I really needed to know 100%

Also to titan cool didnt know that... But I guess they have to protect there research lol

stock gtr dump pipes wont clear the 30 block as there is a big overhang section on the top section of the block that Bubba also mentions. I have done the 30 into a 4wd car (stagea) and just used a 2wd sump for the time being and pulled the cv joins out of the front axles so i could bolt them back into the wheel hubs to hold the wheel bearings together. The dumps do need to be lengthened and not just 38mm added as they need to be spaced 38mm down but the dump flanges are on a 45 degree angle so u really need to make some new dumps. All the stock water and oil lines can be bent to fit on and the oil drains need to be remade and plumbed into the single oil drain on the 30 block. bonnet clearance is also an issue in a gtr from what ive read too. I also used a set of rb25 headbolts and that means u dont have to tap the 30 block headbolt holes bigger.

Most of the stuff is easy and cheap if your willing to get stuck in and also have abit of mechanical knowledge but if your paying a workshop it might be rather pricey.

Rather than starting a whole new thread why don't you just post your questions in the conversion sticky thread?
