Has anyone sucessfully done this swap...everyone keeps shuttin down my idea cuz they say it cost too much money and the vg30dett is better which may be true about the money but is horse**** in regards to the vg being better. I want somethin different and i understand that it wil bel a costly investment and parts are hard to come by but im willing to look past that for the sake of the "wow factor". Please dont tell me that "anything is possible with enough money" and please in the name of all that is holy dont ask why... cuz i already told you.If anyone can give any kind of advice or if you've done the swap and care to give a basic layout of what you did to make it fit, and what to watch out for, etc. Thanks for any kind of advice that you can offer, even about the motor alone is helpful. All i need is a starting point. Thank you

ive never seen those in a 300, though ive seen a rb20 in one.

youre gonna have to get tons of custom stuff done to fit it, so might as well put in the rb26.

i agree. unless you are planning on putting it into a Z31. otherwise, we put the motors into S chassis cars cause they're cheap and light. the power/weight ratio alone in a Z32 would be enough to turn me away from the swap. it has been done, but theres a reason you hardly ever see it. you save money buying a stock TTZ, as opposed to swapping, fabbing up parts, finding all the correct parts, etc for an RB25. you have more power from the VG30 stock for stock.

dont get me wrong, i would love to have a Z. i would have bought one if i had the $ for one. doing this swap, ive spent more than enough to buy a Z. but my timing was ****. so i have a non-running S.....

I can't seem to find any pictures right now, but it is a tight fit. In most of the pictures the harmonic dampener appears to be protruding past the core support. Stealth-Z might be the person to talk to on the forums about this swap.

Now if you are just getting away from the VG, I have seen several Z32s with SR20s in them. Plenty of working room but I am unsure how the motor performs day to day in a 3600lb car.

What exactly are your goals for the car?

Edit: I thought it was Stealth-Z, but I can't find the thread now.

Its possible and has been done.

I helped on one of these swaps at a local shop here. The customer had some problems, and the car sat at the shop for a long time.. Eventually he came and picked it up.. My guess is lack of funds lol.

There is a lot of custom work involved! If your not doing this yourself it will be very very expensive. I'm sorry I dont have more specific info on this swap, but we didnt get very far.

didnt one of the Z32 non turbo models come with an RB25DE? I'm fairly certain...if so, that would make it almost easy to drop in an RB25DET.

It wasnt an RB20DE it was an RB20DET the car chasis was a z31 and the car was called the 200ZR which WAS released in japan, also following a VG20ET, VG30E, VG30ET, and a few other models with a total of about 5-6 models all named differently.

My neighbor just finished a rb6dett swap into his 90 TT Z. I'm not sure if he posts here or not but I'll get him to get on here and post some pics. It's a snug fit and he had to do some custom work but it's a nice setup. If anyone is going to SEZ In Reynolds, GA this weekend me and him will both be there with our RB Z's.

I'm interested in this swap as well, can anyone tell me how this will affect my weight ratio. I'm looking to increase my cars drifting ability, and have been tossing around a lot of ideas. Being a 2+2 it is longer than the 2 seaters, and it has the gas tank behind the wheels. The weight from what I've been able to learn is close to 50/50. To swap into this I would not want to screw with the weight to much, so the vgdett is probably out.

RB series motors into Z chassis is nothing new.

Has it been done, yes. I dont know how intensive the labor is or what is required but has been done, in Z31,32, 33. and older Datsun's 280z and such.

Here is a video of one of the Japanese tuners Esprit, RB26DETT into Fairlady Z33, this is a build I would like to do in the future. Love the body of the Z33 and RB26 motor sound insane. Enjoy , from what I can read its a stroker 2.8L with HKS cams and other supporting mods, still 2 snails. 600ps http://www.youtube.com/watch?v=RrjNHHBGSXo

Seen a black Z32 with RB26, single turbo I think on youtube but cant find it now.
