Can you put up a photo of how you have it connected now?
I am curious to see what you have done?
 
What do you mean by right hole?

Ill post a photo when I get home,
In about 10 minutes

Well there's a hole in the same vicinity of the csi hole on the old manifold

So I figured it went there but a thinner injector to suit the manifold

Because I can't see a suitable reason for that hole to be there other then for a csi

I don't like doing things dodgy I want to sort this out ASAP so it goes back to the way before the new manifold
I'd like to keep the ported manifold so maybe a custom hole.

If the hole you are referring to on the new manifold to is threaded it may be for one of those screw in filter things for vacuum line to connect to?
 
But yeah put it back the way it was. Most likely a fire hazard the way you have it now.

Ahh that makes a lot of sense.

Can I custom machine a hole into the manifold? Or not really?

Also am I able to bypass the csi unit, and delete it completely ill do some research on it, but if any can help me out in custom making a hole or even deleting it that would be great :)
Thanks so much mate you have been a great help
Ill get that photo soonish

If you get the jdm fuel rail to suit, then it won't have the feed forthethe csi.

  If you can't plumb the complete injector unit (see pic)
into the new manifold post the throttle body properly,  best to block off the fuel line to it and not have it operational at all.

Failing that, as Mrskylighter says,  refit the old manifold, at least you'll have proper cold starting.

Yeap,
Ill just fabricate a hole big enough to put it in using the threaded hole that's drilled already then make a bracket up to fit it to. I think Is my best option or yeah remove it for the old manifold.

Thank you to everyone big helps :)

UPDATE;
So today I unbolted the manifold then attempted to drill out the hole I had the fuel line plumbed into but the hole wasn't even going into the manifold it was just there I would say for a braket or to bolt the manifold down to the head not to go Into the manifold at all so
I drilled the hole into the manifold then started going up sizes .5mm at a time until the injector fit finally at 8mm I had some luck it got perfectly
I bolted everything back together started the car checked for leaks there were none but just incase I
(for now) used selastic to seal it to avoid any air sneaking through

So got to keep the manifold and do a pretty decent custom job at the same time and the csi is still doing its job
Everyone's happy :) thanks to everyone for there input on this. Hopefully this can provide a guide if anyone else decides to do this..

Picture time: (where the csi is bolted into.)

It looks like you've just drilled a hole large enough to stick just the end of the CSI into it???
What you want to do is replicate a similar mounting method that the old manifold had. In the old setup the body of the injector was inside the manifold as well as the end.
And how have you secured the injector to the manifold? Have you just pushed it into the hole and are hoping it doesn't come out?
 
If it falls out and you don't realise there's a nice fire hazard.

That's exactly how far it was in the old manifold it goes all the way into the manifold ATM it's just in there won't drive it until a bracket is made up/ it's at least selastic it in.

But the only thing different on the old one it there's two screws either side of it..

Also there is no way it will come out because the metal fitting at the end of it that connects into the fuel line is pressed up against a bracket that looks like it connects to an engine mount/anchor point to get the engine out

It was a very tight squeeze.

Sorry mate completely understand what you meant by its just the end,
Will pilot out the hole more until the brass section fits, in sorry about that, but yeah then it should be fine :) thanks mrskylight

No worries mate. I'm only trying to help stop a potential engine bay fire.
On that, have you installed an extinguisher?
 
Every now and then an MR2 burns and everyone runs out and buys extinguishers. For about $30 its cheap insurance.
 
Most mount the bottle in front of the passenger seat where it can be reached easily in the event of a fire.

+1 for fitting a fire extinguisher.
About $30 for the 1KG type with metal mounting bracket.
I also fitted mine to a metal strip between the front passenger seat bolts.
If you mount it low it should not interfere with seat sliding forward.
