Here's the deal, I have a hose leaking coolant that sits under the stock intake manifold. Since I'm going to have to take the intake manifold off and get new gaskets I was looking at just getting a new one.
I'm looking at getting the Isis intake maifold and was wondering if there was anything else I would need to get to make it fit properly. I have a Godspeed Intercooler and a SARD Fuel Rail if that helps. I did some research already and it looks like the stock throttle cable bracket fits fine on it and so does the IACV. I'm worried about the piping fitting correctly and what to do wit my fuel rail and injectors. If anyone has installed the Isis intake manifold before that could give me some advice before I buy it, that would be awesome.

I didn't realize Isis was junk. I have a lot of Isis parts and they run great. I'm not about to spend $400 more for a brand name.

ISIS is good. Don't listen to these losers that pay 2x the cost of something so they can put all the brand names in their car sigs and not actually drive their car hard.

I've got a ISIS short shifter, power steering line and RUCA and they are fine.
I wouldn't trust Ebay brand stuff, but ISIS is legit and sold by compaines that have a reputation to keep.

and this is why the import market is going down the shitter,

Buy quality parts that have real R&D Behind them.

Don't replace your intake manifold if you are still below 400whp. it's really not that useful you will loose low end torque and fuel economy. Take your manifold off, bypass all the heater hoses under the manifold, clean it up and install it with new gaskets.

Bypass all the heater hoses?

I have one and did not notice any loss in low end and the ports were all pretty smooth. it looks a lot better and it makes working on everything on that side so much easier including oil changes, iacv, coolant lines, wiring. I felt no need to spend 600 on one when I should "lose" low end power and dont plan on making over 400 so I wouldn't notice the difference in the brands, also greddy would not of gotten any of my money either way because the other option would be stay stock I could spend 600 on alot of other things

I needed a s14 cold pipe, s14 throttle cable bracket and I had to modify my throttle cable bracket slightly

You just made my day. That is every reason I want one. You just confirmed what I needed to know. Can anyone tell me how you hook up the injectors and what the heck I am supposed to do with my fuel rail since it won't be going through the top of the intake manifold anymore. Also I'm wondering if my Godspeed intercooler will hook up to it w/o having to buy the Isis cold pipe or will I have to do some custom cold pipe work to ge this work.

I was able to use the stock fuel rail the only other thing i needed was the greddy fpr swivel adaptor. and the s14 stuff i edited into my previous post

I don't have a stock fuel regulator, so that should not be a problem for me. I was planning on getting the Isis pipe that goes with it so I KNOW it will fit properly. Also I saw that you can tweak the s13 throttle cable bracket to fit. The only problem I read was that the fuel rail doesn't line up quite right and requires a dremel. My biggest concern is the cold piping. Thank you all for the help.

I had a GReddy manifold for a while. Isis is the same design, on my s13 I had to modify the throttle cable to fit properly, also had to trim a few pieces of metal off the stock fuel rail. No biggy. You also need a "greddy style" cold pipe. But it really doesn't makes any difference unless your making 400+hp if your not don't bother buying one unless you just want to semi clean up your engine bay. And yes you do loose some low end power, but gain on top end but you wouldn't notice a difference on a stock setup you might reach ur full boost maybe 200-400 Rpm later.
