Guest Kaiyin Posted July 9, 2005 Share Posted July 9, 2005 Well, I'm going to try and swap in a RB20DET into my Z32 300ZX. Has anyone done this before? Links? Advice? Warnings? Thanks. Quote Link to comment Share on other sites More sharing options...
Guest Battle Pope Posted July 9, 2005 Share Posted July 9, 2005 Why an RB20? Doesn't that seem a little... underpowered? Quote Link to comment Share on other sites More sharing options...
Guest Kaiyin Posted July 9, 2005 Share Posted July 9, 2005 Why an RB20? Doesn't that seem a little... underpowered? Yeah, kind of a weird swap, but there's a RB20 sitting at the shop I go to and they'll give it to me if I want to try and swap it in. But I can upgrade turbos and build the motor up. I just want to try the swap out. Quote Link to comment Share on other sites More sharing options...
Guest Battle Pope Posted July 9, 2005 Share Posted July 9, 2005 Give it to you as in for free? Free is good. It will be pretty underpowered untill you build it quite a bit though. Basically, just get the engine, an RB20 5-speed RWD trans, a custom driveshaft, and go to town. Build the mounts and wire it up. Quote Link to comment Share on other sites More sharing options...

It came with a trans. to. I found some figures on the Silver top RB20 which is what I got. r32 (Sliver top) Nissan RB20DET 2.0L Straight Six Capacity: 1.998L Induction: Garrett T28 Turbo charger, 7psi Valvetrain: Double Overhead Cam, 4 valves/cyclinder Bore x Stroke (mm): 78.0 x 69.7 Compression ratio: 8.5:1 Maximum Power: 160 kW @ 6400rpm Maximum Torque: 263 Nm @ 3200rpm Redline / Cutout: 7500rpm Quote Link to comment Share on other sites More sharing options...
2003z Posted July 10, 2005 Share Posted July 10, 2005 thats 215hp/193 ft lbs to us non metric folks, almost as good as the NA z32 Quote Link to comment Share on other sites More sharing options...
240Z_Master Posted July 10, 2005 Share Posted July 10, 2005 Well, I'm going to try and swap in a RB20DET into my Z32 300ZX. Has anyone done this before? Links? Advice? Warnings? Thanks. Well i'm assuming your Z32 is N/A I hope. I would definately go for the RB25 if you were planning to do this. There is going to be some major fitment issues, be careful of the turbo and downpipe on that side. However, I have seen a 2JZ into a Z32 but this was in the Middle East from those TopRpm.com guys. If it makes you happy, go for it, but try at least going the RB25, RB20 seems a little too weak. I mean the 200ZR came with the RB20, but do as you please. Good luck!

The reason I'm going with the RB20 is I'm getting it for free with a tranny. So, I'm going to try my luck and see if I can get it to work. I do have a back up plan though because I'm picking up a 300ZX TT front clip on monday. Quote Link to comment Share on other sites More sharing options...
Clifton Posted July 12, 2005 Share Posted July 12, 2005 A VG30DE makes as power as an RB20DET. For all the work you will do it will not make any difference in perfomance and drivabilty will be worse with less torque. Turbo the VG. I would never give up displacement.

b__sosick Posted July 12, 2005 Share Posted July 12, 2005 it would be a cool swap, just because I don't think it's been done. Plus I'm the biggest RB series fan boy that there could ever be. I'd defiently bore/stroke it, as it's horribly underdisplaced for a six cylinder. and free is free!

Guest PROJECTRB240SX Posted July 12, 2005 Share Posted July 12, 2005 Swap In The Rb20det Silver Top.... Get Used To It Then Later Down The Road Build A Rb25de Non-vvt Headed Rb30det. This Uses All The Same Sensors, Wiring, Manifolds, Etc. As The Rb20det So It Would Be The Most Direct Swap And Can Make Some Awesome Power Figures. I Recommend If You Go This Route To Use The Rb30e Block And A Rb25de Out Of A R32 Gts. Quote Link to comment Share on other sites More sharing options...

BIZERK Posted July 12, 2005 Share Posted July 12, 2005 I know there is a rb26dett swapped 300zx and i think HKS did it. It is quite a ridiculous looking peice of work due to the huge tear drop in the hood to accomodate the exhaust manifold. If i can find a link to it i'll post it up but as of right now i cant seem to find it. Also, rb20det's run 10 psi stock. Quote Link to comment Share on other sites More sharing options...

240Z_Master Posted July 12, 2005 Share Posted July 12, 2005 With the specs of the RB20, why not go with the 25? I know its free but might as well do it right.

Guest PROJECTRB240SX Posted July 12, 2005 Share Posted July 12, 2005 I Personally Like The Rb20 Over The Rb25... I've Owned Both. The Rb20 Just Seems To Rev Easier And Feels More Racy On The Topend, While The Rb25 Has Alot Of Grunt Between 3k-and 6.5k Rpms. It All Depends On What You Want.... I Would Just Build A Rb30det And Call It A Day If I Was To Do Another Rb Car. Quote Link to comment Share on other sites More sharing options...
