EMWHYR0HEN Posted February 14, 2006 Share Posted February 14, 2006 I dont know if this is just a 25 manifold cut and welded on butterflys or RB26 intake manifold cut, but Anyone know what needs to be done to fit RB26DETT intake manifold on an RB25 Head?

christiansagun Posted February 14, 2006 Share Posted February 14, 2006 Does the rb20det drop right into a 240Z engine bay using stock skyline mounts? Quote Link to comment Share on other sites More sharing options...
Ed260Z Posted February 14, 2006 Share Posted February 14, 2006 You'll probably want to go with the 4.11 rear in the car. It will give you a better launch, and good on road characteristics. Should knock off over 1 sec from your time. I'm pretty sure you won't be able to fit the 26 intake on the 25, with out some serious fab work. That intake looks custom, or may be JUN, MINES, GREEDY, ect............ Quote Link to comment Share on other sites More sharing options...
twistex Posted February 14, 2006 Share Posted February 14, 2006 i have a 1984 nissan maxima .. datsun maxima i should say! rwd... it comes with a 2.4 liter inline 6 l-series .. you all probably know that! also the other cool thing is it is a front sump motor like the rb.. and xmember looks similar to a z but just for a front sump .. anyways i think it would be sweet to toss a rb20det into that thing .. it has irs and rear disc. i also put a 4:11 r200 in it. problem is i never see anyone drifting or racing those things. i have searched all around under datsun 810 datsun maxima .. dont find verry much. anyways another thing is when i pulled the motor from the maxima the soft motor mounts looked identical to rb20det rubber mounts .. it was werid Quote Link to comment Share on other sites More sharing options...
christiansagun Posted February 14, 2006 Share Posted February 14, 2006 Sorry guys... Is my question really that dumb? My motivation to do this RB swap just went down. <--EMO... hahah. Quote Link to comment Share on other sites More sharing options...

All of the RB's have the same block. you need the mounts from a 200ZR (JDM 300ZX) to drop it into the S30. But this does not mount the engine in the ideal location. There are several posts on this subject already. Quote Link to comment Share on other sites More sharing options...

But this does not mount the engine in the ideal location. There are several posts on this subject already. Yeah thats what I mentioned before on the other page. the static weight might be ideal, but I have read that the kenetic weight (into the corners) cause the car to understeer because of the center on gravity being high.

z_cars_rule Posted February 15, 2006 Author Share Posted February 15, 2006 It might be a different story in the S130 though, I have not noticed any increase in understeer, even though i have no powersteering hooked up at the moment. Quote Link to comment Share on other sites More sharing options...
Ed260Z Posted February 15, 2006 Share Posted February 15, 2006 The big problem is the the S30's aerodynamics SUCK in a big way. So the car is inherently unstable to begin with at speed. The lower you can make the CG the better. Rick Wong and Q (240Z Master) both make mounts for the S30 that will put the engine as low as possible. But I think the Q is still refining his design.

z_cars_rule Posted February 15, 2006 Author Share Posted February 15, 2006 Yeah i noticed my 280zx was just a lil light at the front when i hit 143 mph with the old motor. not doing that again until i get new suspension and maybe a front lip.

The mounts are pretty much done, just have to finish getting them made from my guy, which is taking a lot longer than usual. Quote Link to comment Share on other sites More sharing options...
