Nismo280zEd Posted June 5, 2006 Share Posted June 5, 2006 Ok, so i know the 200sx 300zx and maxima all have the VG30E engine, as well as the altima I believe, so my question. Will the camshafts made for the 300zx VG30E engine... work in the maxima VG30E engine? Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted June 6, 2006 Share Posted June 6, 2006 I'm going to say yes. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted June 6, 2006 Share Posted June 6, 2006 They'll swap but to my knowledge they are all the same, even the turbo ones. Over seas they had different options like the "Euro" cams, which were supposed to add roughly 10 hp on turbocharged VG's. I'm pretty sure the ones in the US never really got any sort of cam change. I've never seen anyone post specs though so I'm not 100% sure. Quote Link to comment Share on other sites More sharing options...
Guest Jason84NA-T Posted June 7, 2006 Share Posted June 7, 2006 They do interchange, but yes, they are in fact different. The truck and maxima cams are lower duration. The euro cams (not j-spec, only euro) had a 12 degree longer intake duration and 10 exhaust, with the same lift resulting in a 10HP gain on a stock engine, the early cars also came without a cat speculated to be yielding another ~16HP... hence the 226hp rating in europe. I've also heard the turbo specs are a little different on those cars, but that has not been proven. This cam information was pulled from various versions of FAST (for OE specs) and took a while to compile: http://www.redz31.com/pages/caminfo.html Quote Link to comment Share on other sites More sharing options...
mtcookson Posted June 7, 2006 Share Posted June 7, 2006 Going by your link, all of the US W-block engines had the same cams. The truck and Maxima cams have the same specs as the later Z31. That's how I always thought it was. Quote Link to comment Share on other sites More sharing options...
Racinjitter Posted June 7, 2006 Share Posted June 7, 2006 what about the villager/quest? are they the same as the Z31's? Quote Link to comment Share on other sites More sharing options...
Guest Jason84NA-T Posted June 9, 2006 Share Posted June 9, 2006 what about the villager/quest? are they the same as the Z31's? I would assume all W-series VG's (4/87+) are the same. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted June 9, 2006 Share Posted June 9, 2006 Actually.. I bet the cams in the Villager/Quest VG30E changed. From what I can find the bore, stroke, and compression ratio are all the same however... it is non-interference. From what I hear, Ford basically told Nissan to make it non-interference for the van. This explains why the overall specs of the engine are the same except for power output: 151 hp @ 4,800 rpm 174 tq @ 4,400 rpm Quote Link to comment Share on other sites More sharing options...
Racinjitter Posted June 10, 2006 Share Posted June 10, 2006 MAF was completely different than our style, I was just wondering. Come to think about it one of the villagers that I had to work on broke the camshaft pulley pin and no damage was done to the valves or pistons. ran perfect once I fixed it though! I compared the heads once off and couldnt see any differences in combustion chamber or valve sizes. Quote Link to comment Share on other sites More sharing options...
Guest pete 308 Posted June 10, 2006 Share Posted June 10, 2006 Ive got a Nissan Navara with the VG33E.What would be the best supercharger for it? Quote Link to comment Share on other sites More sharing options...
mtcookson Posted June 10, 2006 Share Posted June 10, 2006 The best supercharger would be a Lysholm or Whipple screw s/c (Whipple being the better of the two). The Whipples are very efficient and give nearly instant boost. The only downside to them is they can be very expensive. The Lysholm is the same type of s/c but isn't nearly as efficient as the Whipple. Their 1.2 liter units have an adiabatic efficiency difference of 17%. My next supercharger pick would be an Eaton roots supercharger. An M90 would probably fit best with the 3.3. They are very inexpensive but at the same time are the most inefficient of the superchargers. You can also use a centrifugal supercharger like a Vortech, Paxton, etc. They can be very efficient like a turbo however boost is linear so you don't reach peak boost till redline, which to me is a major downfall of the centrifugal supercharger. So... basically if you can find one I would use a screws supercharger. If not, an Eaton M90 roots. The overall most efficient setup would of course be a turbo due to having a high adiabatic efficiency and not having the parasitic losses an s/c has, but if you absolutely want to go with a supercharger I'd go by the above.

I guess that's one way to do it. Quote Link to comment Share on other sites More sharing options...
mtcookson Posted June 14, 2006 Share Posted June 14, 2006 From what I can tell... yes. The bore, stroke, and compression ratio all appear to be the same from what I've found so that leaves either changing the timing of the cams or the lift.

bigal Posted September 26, 2009 Share Posted September 26, 2009 I know this is an old thread, but the non-interference motor on a quest has slotted piston faces, so even if the piston all the way up and the valves are all the way down, they never make contact I guess its a safety mechanism for all the soccer moms who are to busy to have their timing belt replaced Quote Link to comment Share on other sites More sharing options...
hoov100 Posted September 30, 2009 Share Posted September 30, 2009 dude, its gonna take more then valve reliefs to make a non interference motor, you would need one seriously dished piston or have a very small lift cam, someone needs to go to the junkyard and pull one apart completely and compare it part by part to a regular vg.
