DETurbine

Seeing if anyone knew if the R34 Neo 5spd manual transmission will work on the R33 RB25DET?....I have an S13 right now with an RB25 in there and had the stock R33 5spd, but it gave out and cant find that many R33 transmissions around. Found this R34 Neo transmission that I can pickup, but wanted to make sure that the bell housing would bolt up to the back of the block without a problem and also check to see if it is the same general overall size so that I wouldnt have any troubles with the tranny tunnel or driveshaft that I had made for the R33 setup. Thanks

Does anyone know if the internals on both the Z32 and R33 Rb25 transmssions are the same. I have heard from others that they are the same, only differance is the shift linkage, outer casing, and the bell housing. I have a RB25 trans right now that the cyncro had went out. I was wondering if I can take the 300zx internals and put the outer casing, shift linkage, and bell housing on and make it work... Help would be great, Thanks... ***I live in the USA and RB trannies are very hard to come by, if you find them they are upwards of $1k usd....the 300zx can be found here for $250-300 on average.

Has anyone done this or can confirm that this can or can not be done?

We are not running the power fc, so we do not have the capability of adjust it. We need to totally take it off or disactivate it.

I am running a new stand alone that is some what a DIY setup. I have known that you can take this out and disactivate it, but is it more then just wiring or do you have to physically take it out some how? Or is it something that we could trigger with a new stand alone? How is it triggered with an on/off at a certainor RPM or does it use a pulse width modulation? We will not be using the stock coil packs or ignition system....we are actually using a Ford Edis 6. Help would be greatly thankful.

ok thanks for the reply and info. Now the next question is are the internals of the transmissions the same?....could I use a VG30DETT 3/4th syncro gear in my RB25DET transmission?

I have heard that this can be done, but am not sure if it is the true or false. If it does work work what tranny can you use (VG30DE and/or VG30DETT)? My RB25 tranny has gone out and I can get ahold of a VG30DE tranny here in the states for $200. If I were to get ahold of a RB25 tranny it would at least cost me around $800+. Help would be thankfully blessed.

Is the ignitor actually inside the ecu or is it in the coilpacks? I have heard both about equally and am trying to figure out which location is true. I am throwing together a stand alone system that has not been done before on the RB's and that is one thing I need to figure out. Thanks,

Well I am just getting my motor done and have kinda put off my RB25DET manual tranny which the 3/4 syncro started to go out. I have heard from others that the Fairlady/Z32 300zx VG30DETT tranny internals are the same. I can get the syncro from Nissan out here in the states for $130usd, but want to make sure that they are the exact same before I spend the money. Can anyone confirm that these are the same internals?...has anyone done this yet?

I wanted to find out what is an average of what the stock RB26 444cc injectors will support (HP)?....I was figuring it out myself and was thinking that they could probably handle 400hp with an aftermarket fpr....and crank up the fuel pressure a little. Help would be great.

I am wondering if Supra 2jz injectors will work on my RB25? To me they look like the same size and connector size. From what I have kinda put together they are just like the RB25's and 13B Rx7 injectors, but I am not totally sure. Just wanted to find out if anyone else has done this or know if it can be done.

Just wondering if anyone has tried these exhuast manifolds out. If so how are they holding up and how do they flow?

I will not be using my car for the autocross or anything like that. I am using it for drag and that is it, so getting the best response is not my number one goal. My setup is going to be working perfect for me and I am not going to spend that much more to get a little bit more response and a few more horse. Not sure about over there, but people over here in the states are into building their own and I have seen the exact same design plenums as what I am doing and they have got great results. I too am building my own motor, just taking it to the machine shop to get all the machine work done, then me and a few friends will be putting it back together, fixing my tranny, and fabricating all the parts for my turbo setup and so on. I guess you can just call me a cheap DIY kind of guy, but it has been working for me and my friends for some time now.

Was thinking more on the lines as if they were welding their own plenums. I can get one made as I had stated....for less then $500. Just need to go ahead and ask them if they will draw back the price if we get a group buy from them. Will talk to them allot more this week, as I have not talked to them for a few months about some things.

Give me $500....and I will make you a peice just like theirs that will flow just as much and even come with velocity stacks to help out the flow even more.
