id rather just buy a bigger performance intake manifold thats used on drag engines and what not because the cyclone intake manifold isnt a direct hook up, i hear you have to do ecu mods and wiring to get the butterflys in the manifold to open right or theyll just open all at once and be like a regular stock manifold.

Your correct on forged internals, just as the 4g63t without the cyclone intake, they have them too, with out forged internals and still having a turbo, youre digging yourself a hole. I'm sure you knew this, maybe i just read it wrong.

You, sir, should stop speaking. The JDM 4G63 motor does NOT come with forged internals, period. Our cars don't come stock with forged internals, and the stock motor has produced some hellacious HP numbers, on CAST internals. Don't speak anymore until you actually have some knowledge of DSM's .

If you have DSMLink the Cyclone is wicked easy to set up. If you don't, you would need an EPROM ecu and a Keydiver chip to CORRECTLY actuate the butterflies. There have been several people who have simply used a wastegate actuator from a T25 to open the butterflies, but this somewhat defeats the purpose, as the system is designed to operate from load/RPM's as opposed to opening off of boost.

Also, some of us don't want a "performance intake manifold" as it kills your off-boost performance. I'd rather sacrifice the 1CFM of flow that the cyclone loses to the straight 1G head, and get great around town off-boost torque, than just have a track monster.

That is completely correct.

there are alot of threads about the cyclone on tuners and as far as i am concerned i am with keymaster cause the 1CFM loss won't make a bit of noticeable difference and there is also a very good thread that details how to set up the cyclone in 3 different ways so that the butterflies actuate correctly. all in all the cyclone is a sweet manifold if setup correctly and is much better for a street car then a racing sheetmetal manifold would be

well looks like i got my self into some trouble, i put the cyclone intake manifold on my 2g GSX and looks like the throttle body don't clear the black thing what i believe is the ISC is hitting the fuel rail and there is no way to squeez it in there(Picture below).... also the manifold does not have brackets for the ignition do i make a custome on or what?**

The black "plug" is actually the TPS (throttle position sensor).

Not sure why it's so close to the fuel rail, I went outside to look at my engine and there is a lot of clearance between the TPS and the fuel rail. Of course this is also a cyclone IM which has different runner length probably.

Is a 1g throttlebody different enough to clear? Fabricating an IM manifold spacer would probably be expensive. Cyclone installs aren't very popular.

Here is another thread on TPS clearance:

Can i relocated the TPS or does it have to be there ... the throttle body is also from a cyclone engine just like the manifold so that might also be the problem it might be too big...

TPS= throttle position sensor= needs to be at the throttle plate/body

GOOD LUCK

It's just a thought, but can you remove your fuel rail, finish off putting your TB on and then put your fuel rail on after?

Do you happen to have a 1g fuel rail on there? I know when I put a 91-94 throttle body on my car I had that exact same problem and just went and got a 91-94 fuel rail and rubber line from filter to rail, it all bolted right up dandy.

right now the fuel rail is off a 90 gst but i'll get the one that i had on it back and try again or i'll try my old throttle body although its a little smaller but i'll take the loss to get it running for now...do you guys think if i go back to my stock fuel rail it'll clear? or should i try my old TB?

The rail is your problem, its got a different angle on it at the end thats why your tps wont fit. Along with that you have to get the line from filter to rail because its angled to fit the 90 rail.

So you think that the 95 fuel rail is going to do the trick or do i need to get on off a 91-94? and what about the ignition do i need to make a custom bracket for it or what?

I'm not sure of the angle at the end of the 95 rail, but I would assume it would work fine.

As for the coil pack I'd get some 1/8" x 1" steel from your local hardware store and fab something up and mount it on your strut tower.

Did you port the head to match the larger ports on the cyclone manifold?

Yes the head is match ported to fit the cyclone in fact that was the major problem i ported it and then decided i would stick to stock intake manifold however the ports were so much bigger that it leaked air out everywhere so now i had to take it off and put the cyclone on.... i'll try the other fuel rail and keep you guys updated thanks for the input!

you could also just pick up a stock 1g IM for cheap and see if that repositions the TPS until you can figure out a way to get the cyclone/TPS issue worked out

Are you using the 1G or 2G TB? That will make a big difference too. For the coilpack, 1G or 2G? I used the one that came with my motor (6-bolt JDM w/cyclone mani) and just left it in the stock position on the IM. You would have to buy some 6-bolt spark plug wires to reach though.

Okay i changed the fuel rail with a 2g (95) and it clears perfectly...so that problem is solved !

Okay so now i changed the fuel rail and the TPS cleared and everything is in place however i noticed there is a sensor on the stock fuel rail (2g GSX) that is not on the cyclone intake manifold.... check out the pics they both are of the sensor that i don't have on the cyclone.

Awesome!

thats the map sensor, 2gs have it, 1gs don't.

run a vac line to the tube sticking out of the bottom and your fine. (make sure its a manifold pressure source and not a pre throttle body source)

there is a bracket for the coil pack on the side, the person you bought it from probably took it off ### they are a douche, the one I have has a bracket on it.

AMS sells the peice that you are looking for. It's called a missing link, It is made by Synapse i beleive. And it's usually for a true complete 6-bolt longblock swap ::

Solid

DSMparts also sells it.
