From what I have heard, the quad throttle bodies do not all line up. Actually, I think the bolts do not all line up to be more exact. Also, are you planning on running the stock MAF sensor, or a different setup? I think you will need the GTi-R plenum if you plan to run the MAF. I could be mistaken though.

I am also going down this road with my fwd sr20de. From what I have seen you need to port match the throttle bodies and drill new bolt holes for the bottom row of bolts for bolting them to the head (the top holes already line up). You will have to use rb20det injectors if you are using a stock ECU and you can use the stock AFM. My car is a 1991 n14 and the TPS, AAV and IACV all plug into the existing loom. And you will have to use a gti-r rocker cover + throttle bracket or make up your own throttle cable bracket.
All good. You need the iR rocker cover because the end throttle cable bracket bolts to it and the oil cap is out of the way of the throttle cable, or if you custom make the cable bracket and mount it some other way you can use the original rocker cover. And rb20det injectors are needed if running a stock ECU because they are the same cc and impedance as the sr20de ones but they are top feed so will fit into the gtir fuel rail.

i didnt plan on changing the fuel rail, just the throttle body. the ITB's should be here within the next week or so. ill have a look about and see what i can come up with and keep the injectors and rocker cover.
its not that im not listening to the advice, just want to try something differnt and without having the ITB's at hand i dont know exactly what they will fit like etc etc
The stock injectors/rail don't match up without the GTi-R fuel rail if I'm not mistaken. It might be worth getting what he suggests instead of trying to do it with the bare minimum since it sounds like he knows what he's talking about. If you wind up NOT needing it, you can always sell the parts after you get your running.
Yea the reason you will need the top feed injectors is because that is what the manifold is set up for, and you won't be able to run gtir injectors on a de ECU because they are too big and the wrong inpedence.
As for the throttle cable bracket, you can make something up like on this car and retain the original rocker cover. (which I would like to do because I'm not a huge fan of the gtir rocker covers):
This is what the factory throttle bracket and rocker cover set up looks like
You will have to re-drill the lower 4 holes where it bolts to the head, the top 4 line up but the bottom 4 don't. And yes use the gtir fuel rail and rb20det injectors. you will most likely have to change the plugs on your loom to match the injectors, and since rb20det looms are damn expensive over here I'm going to get the plugs off an rb20de loom because I think they are the same. You might need to port match the throttle bodies because they aren't quite the same shape as the ones on the head. And you might have to swap around the outer two wires on the TPS since it works in an opposite way to a standard highport TPS.
I have done this and got it running. None of the holes line up. I made a custom cable mount and used rb20det injectors. Some of the wiring needs to be altered. Overall it was easy, for me, as I have all my own welding and machining gear in my garage. There is a lot more to it than 'just drill 4 more holes'!!

Reason: Wanted to add picture.
Was your one the nicely polished one? I have nearly got all the bits to install mine, just need the injectors + injector plugs. Did you have to swap over the TPS wires to run the gtir TPS?
I am using the GTiR TPS with the wiring reversed. I got the sockets for the top feed injectors and cut plugs from old side feed injectors and wired them together to make adapters, saves altering the loom, in case you want to go back.
So you pulled apart side feed injectors to...(holy sh*t earthquake)... make up adapters for the top feeds? I am planning on chopping the top feed plugs off an RB loom but wasn't too keen on chopping up my loom. Have you got any pics of how you did them?
That's awesome. I have a spare set of side feeds in the garage, now just got to figure out how to get them out of the rail. Lol you're not keen on making up another throttle cable bracket are you? I don't have the tools to make one and I'm not too keen on using a gtir rocker cover.
I have been trying to get a whole set of quads from a member of the NX forum, with no luck. I was going to do a whole setup to bolt straight on. What parts do you need? Just the plate, or the threaded cable mount, too?
To remove the injectors, unscrew the caps, replace the screws and use them as pivot points with two screwdrivers/small prybars in the holes in the side of the injectors. Screw the screws out bit by bit for extra height. That is the easiest way!!
Does the threaded part of the stock cable not fit the gtir mount? I have a gtir mount but it requires the rocker cover that matches it to fit. And as for the old side feed injectors, I can't even undo the screws on them lol. I might have to fish out a bit for the power drill and attack them this weekend.
You need the GTiR cover for that mount. You can see in my pics why. My setup was done that way as I didn't have any other parts, apart from the quads, not even the rail or injectors!!
