Hi Guys. I've just dropped an RB30 into my 280zx. The intake manifold only JUST fouls on the bonnet.

Anyone know where/how I can get an intake that will have either a slightly shorter mounting height?

Im considering using the bottom half of the plenum and having a box welded on top.

Thanks in advance.

Im doing the conversion on the cheap.. Im not looking at making big power yet, just trying to build something that works. Ill be changing over to a DET head a bit later on.

I dont know much about aftermarket parts for the RB30 - Every aftermarket intake manifold seems to have siamesed ports at the end to feed a DOHC head, not SOHC.

I cant seem to find anything to suit the RB30E head?

Cheers.

edit - just searching those names you mentioned.. thanks - waaaaay pricey though :P

Sorry missed the bit about SOHC. If you don't want a power bulge in the bonnett I guess you could get a fabricator to modify your stock plenum. When you do get the twin cam head - you can get good and bad Greddy copies - mine was only around $300 and appears to work fine.

      Did you panel beat the dents or have you tried to repair this only using filler?  Is your sanding block soft/flexible and is following the shape of the panel rather then just knocking down the high points?

      I haven't knocked them down yet. I think I made the repair more complex than it should have been. I had rock chips combined with waviness and dents and I tackled it all in one because it was near each other and just end up wasting a bunch of bog lol. I'll knock down those areas and see how I go. And yep what you are saying at the end is correct. I think I might be sanding the top of a steep hill then my sanding block falls into the dent and gets rid of the guidecoat if that makes sense. Though shouldnt unless I'm covering too big of an area with not a long enough block. I'll try something new and provide some updates. Getting there though! Thanks as always.

      Yeah makes sense, hard to comment on your situation without seeing what your doing. I was talking generally before, I would not be looking to randomly create low spots with a hammer to then have to fill them.  It's hard without seeing what your doing, it sounds like you are using the guide coat to identify low spots, as you're saying the panel is still wavy. I don't see how you're not ending up with patches of guide coat remaining in a wavy panel? Once the high spots are knocked down to the correct level, surely to have a wavy panel you need low spots. And those low spots would have guide coat still in them?

      So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?
