Because the wheel base is the same, i don't think there's any difference between the two, but i'm not 100% sure on that. Is your car already turbo? I think all you should need is a turbo manual tail shaft. I think the only difference is from turbo to n/a and auto to manual but not from 2 door to 4 door, but i could be wrong.

Having said that, personally, i would still make sure i had a 2 door and a 4 door tail shaft when it came time to do the conversion.

Some one else may be able to provide some more insight. :happy:

  • 2 years later...

where would i find this info as i just bought a 2 door tailshaft. the only difference i no of is yes between auto and manual and the 4 doors have different boot lights and rear bar and the 4 door is only 50mm longer than the 2 door. if anyone can concrete confirm this it would be greatly appreciated.

you will need to modify the gearbox bracket. The 4 bolt holes that are in the body for the bracket are further forward in an auto, the hole in the floor is also in a different position but thats ok.

what will happen is regardless if you use an auto/manual bracket (they are the same anyway) you will go to bolt up the bracket and only one hole on each side will line up, you will need to either modify the bracket like I did to make it longer and drill 2 new holes for the other two bolts..

OR

get two flat steel bar peices and bolt them to the underside of the bracket, recess the head of one of the bolts into the chassis and drill a hole at the other end of the bar to mount into the body.

you will then need to bridge the neutral park switch circuit so it thinks its in park all the time, otherwise it wont start

cheers for the reply mate. couple of questions

1. if you say the holes in the floor are further forward in an auto that would make them 2 different chassis auto/manual correct? as you said only 2 of the holes line up so is this with the gear box mount connected to the steel plate that bolts to the floor? is there anywhere on here that has a diagram of where to bridge the neutral switch?

thanks.

that is correct.. if you look under your car the 4 holes in the floor are actually a metal panel that has been spot welded around the tunnel. They positioned this peice in one spot for auto and one spot for manual. So yes the bodys are different, but this is the only difference. Auto/Manual tailshafts appeared to be the same length too.

I did find a thread on here on where to bridge it, its a peice of piss. Where the fuse box is in the engine bay there are some grey plugs on top of eachother. I really cant remember which one you do, but basically you splice into one of the wires on one of those grey plugs and you bridge it into another one of the plugs there.. Search and you will find, thats how I worked out what to do

    • GTSBoy on your suggestion on another thread I had a look at those injectors and ended up getting them because of the quality.  Got the expensive ones.  
    • Hey guys been looking everywhere to try and find the correct gtr hood latch support part number but only found the first half and when I search with that number it sends me to an r34. The first part I found was 62515. If anyone could help me with the rest then I’d really appreciate it. Or if there’s some alternative hood latch support that would work even better cause I can’t find any for sale. (Searched on upgarage, partsouq,buyee,rhdjapan) 
    • If you've only done the upper control arms on the rear, AND you have changed their length (by more than about 1mm) to set the camber you want, then you will definitely need/want to install traction arms also. Adjusting the camber arms on their own WILL introduce bump steer and make the car unpleasant to drive. Most owners have no idea that their car could behave infinitely better than what they put up with. I'm not entirely sure what the Stageas need, but I am thinking that unless you have massive front spring rates and pretty soft rear springs, you have waaaay too much rear bar. Oversteer city, in my estimation. Combined with possible excessive bump steer from maladjusted arms, that could be a recipe for nastiness. ATR43SS2 is not a highflow. It is an outright replacement turbo. It's a little bit bigger than the largest highflow profile that Tao does. Probably a solid 300rwkW turbo where the bigger highflows will be about 30-40rwkW less. Nevertheless, we're only talking about ~300 rwkW, which is well within the abilities of the stock ECu to run with a Nistune on board. I would do so without hesitation - and I will be doing so when I get my finger out and actually get the injectors and AFM installed. But, if you would prefer to drop a whole lot more money on the ECU side, then I suspect you're looking at Haltech. The Haltech fanbois here will all spout on about all the available engine protection you can have, that you can't have with the Nistune option. And they're right. But it doesn't really come for free either. You will spend more money on extra sensors and the like, plus the work to install them. If the engine was built and therefore represented a big investment to protect, then I'd say definitely do it. If you view the current (and forever into the future) shortage of replacement engines as something to prompt similar protection, then also, do it. If you see a destroyed RB25 as an opportunity to put in a Mercedes or other V12 (like I kinda do)... then your perception of the risk/reward might differ. These are good injectors. You can also get a "better" set of the same with more flow matching, for more $$. 1000cc is where you will want to be. You will need an R35 AFM and adapter tube if you want to stay with Nistuned stock ECU. Otherwise, if going Haltech, you can ignore. As for intercooler. Just about anything will do. You're only talking about ~300rwkW. Just put a big core in there. Be aware that return flows do add significant pressure drop and will cost power and will make the turbo work harder to achieve the same goals. If you can manage a proper crossflow, do it. I'm keeping my very good return flow because I'm only expecting to be in the ~250rwkW range, and will live with whatever outcome I get.
    • I have a heap that i have collected if you want some authentic ones still. Pm me if your interested!
