Na Rb30/26 Manifold Help

[Snoopy Performance]

hi guys how r u all ???

i was just wondering if anyone could help me with some advice with finishing off a car a friend of mine has brought and wants me to finish for him. he recently brought a vl from a old couple who were clean out the yard of their sons stuff that was left there (he passed away a few months ago) and it trun out the car has fully re-built stock rb30de with a rb26 head fitted and wired almost ready to run (no manifold). my question is could i use the following parts to finish it off for him.will a stock NA RB30 Intake and Exhaust manifold bolt to the rb26 head ??? (It has to stay NA and look stock as he is only on his P's and can't drive a turboed car {we're in NSW} ). also where can i get a fully enclosed timing belt cover to suit a RB30/26 as it has no timing belt cover at all ??? any help will be muchly appreciated

thats a pretty amazing find.

The only stock manifold that will fit the rb26 head, is the stock rb26 manifolds, they arent interchangable with the rb30.

You could just use the stock rb26 inlet and have the afm on the drivers side of the car instead of the passengers side, but a custom exhaust manifold (extractors) will need to be made up at an exhaust shop. There arent any n/a rb26 so theres no aftermarket support for na extractors.

Are you sure it was built with n/a in mind? it seems like a waste for such an engine to be n/a haha

For the timing coverside of things, a rb26 cover needs to used but you will find there will be a gap where it meets up with the bottom timingbelt cover, since the rb30 block is taller than the rb25/26 blocks. To do the job properly you need to weld a piece of sheet metal to extend the cover so it meets with the bottom cover. I wouldnt recommend driving around with no timingbelt cover, you dont want dirt floating around in there.

doesnt the rb25 timing belt cover fit in a pinch with slight mods???

i would buy the RB26 intake & timing cover from the yahoo japan auctions.

exhaust manifold/extractors would need to be a custom job; buy some coby extractors and get the flange modified to fit

to get the rb25 to fit you would need to use the backing plate from the rb25 otherwise it wont bolt up, but you would still be left in the same postion with the gap where it meets with the bottom cover (cause the rb30 is a taller block the covers wont cover the whole belt). Just use the rb26 cover and modify it to cover the whole belt

As said all above..

get a set of rb26de headers and change the flange around to mate up with the rb26 head..

how did enlargening the wholes for the head studs go?

*sigh*.. its not a set of rb30 headers.. maby a set of 26 headers!?!

You could always get the Autech ones..

lol..

Get the coby's. There is some flanges to suit the 26 on eBay. Or is it in the for sale section?............

That would be one wicked beast!
