Cyclone intake Manifold

Ok I just got the manifold i bought back in october from this guy. Now i know that you all said that its a waste of time, and you need the ecu to run it the way it is suposed to work, this however is not true. But anyway that is not the point I know that i need to have a 1g head to put it on and i am looking at one now. If any one has one that you are selling just tell me how much and i will compare. I was wondering where i could find a few parts to run this manifold. It came with the tb and sensors for that and the vac canister that controlls the butterfly valves. Now i need to know Where i could find this white canister that also connects to the set of vac lines that controlls the second set of runners and how much is it. And some of the other parts from this site and i need to know where i can get the and about how much they are going to run all together. I only paid 40 for the manifold shipped so i would say i got a good deal on it and its cheaper than a sheet metal

this is the site i found so i just need to know about how much these items are going to cost and where i can find them if you could help that would be great make my day easier.. If anyone know were you can get gaskets for this thing please tell me if it has any

:nono: you need the damn ecu, and second i hope sobody will conferm this or disprove it but dont you need a 6 bolt block to run a 6 bolt head???

No, you can run a 1g 6bolt head on a 2g 7bolt no problem. In fact, it's a quite common swap (coupled with a 1g intake manifold) with 2g's.

Did you go the site and see how he had it set up on his galant vr4 he says you dont you just need something to controll the second set of runners to open at a certain time I believe that he called it a normally closed;or normally open pressure valve. So there are other methods of doing so. It is just ran on a set of vac hoses and a pressure switch of some sort he has it under some napa part# blah blah blah. But According to V-faq you can run it without the ecu.

Whats the point? Having extra clutter in your engine bay for better throttle responce that some guy says he gets?

Until there is proof of dyno results or something that shows me numbers and facts, I'm not even going to look at them for any reason! 1st gen manifolds are just as good and take no work to put them in our cars. I'd also rather have 4 big ports to flow more air smoothly than 8 small ports and a plennum. Thats just another place for boost leaks!

I have a 1G Head for sale. toss me an e-mail

Better or not that is not what i am going for at this moment i want to see what it can do? I just need to know where i can find these parts and roughly about how much they are going to cost This is all I want to know. There are several forums that say what you are saying. So if someone could tell me i would appericate it. And i will tell everyone wether it was worth the trouble of doing it.

Well if you are looking for info on where to get that stuff I suggest emailing the guy that did it! No one hear has done it so we dont know!

i know that keydiver sells chips with cyclone mani controllers built in. but you still need to buy the solenoids somewhere

Yeah i don't know where i can get all of the parts but my friend is going to sell me his 1g head for 20 bucks i have to replace all of the valves because he sliped his timing and fucked them all up so now i need to find some valves also but all of the lifters are new.

Better hope the valve guides arent fucked up!

all of the lifters are in the down postion I couldnt really see them because it was dark but as i said its only 20 but im pretty sure everything else is fine

instead of buy a whole new set can i just transfer all of the stuff from my 2g head to the 1g head?

If you have the head I still have all the valves and lifters and cams if you want them. You have my e-mail address

So.. how do you remove the valves and lifters from the head i know that they just dont pop out?

u need a valve spring compressor i think and you have to make one your self or buy one off dsmtuners, i think i saw a couple off there, i dont know what else you need but kevin will probally comment soon and tell you, or jake

i hope you were joking about that last post. if they just "popped out", how in tht hell would your engine run? you can make a "home-made" valve spring compressor. www.vfaq.com shows how but i would just take it to a machine shop and they should be able to do it in 15 minutes for you, although it might cost some $$, at least it will get done right.

yes i was kidding i know they just dont pop out would the mechanic have one i was going to let him do the head and all I need my car back in one day and I don't have any of the tools to perform the swap

yeah i would let your mechanic pull out the valves and stuff, he should have the right tools for it.

Well i have good news and bad news the bad news is that as i said before the valves are toast there is nothing that could be done for them how the hell do you break one. Good new the head it self is in great condition. More bad news i can't find a gasket for the manifold anywhere so i guess i will have to make one that kinda sucks but it could be worse. Good news the two parts together cost me 60 bucks.

Alright I now have all of the parts to run the manifold i found a sheet of gasket stuff that can be cut to whatever shape needed. I found the hobbs pressure switch. I couldn't find the vacuum canister but i got a vacuum ball from ford and it is supose to have the same affect as the canister. All of the parts are cheap so that wasn't a problem. It was hard as hell to find them but i figured it out. So tomorrow i will get the 2g head pulled off and monday I will get the 1g head set up for use... So I will soon see how much power this thing adds. I'll try to get it on a dyno and give you some numbers. As of now the car has this on it


cone air filter
flow master muffler
type s bov
autometer boost
autometer a/f
autometer oil pressure
greddy turbo timer
est hp 230-240
boost guage reads 18psi

Are you using the stock turbo?


If you are going to look for how much power increase there is you should dyno it before hand instead of guessing that your at 230-240 which even at 18psi it would be the most at the crank you could probably get out of that little T25.

Anyways, when you do get the manifold on you are still going to max out the turbo so the manifold really isnt going to do much for you, maybe make spool up a little faster but its not going to give you any more power unless you have a bigger turbo. Even if you do have a bigger turbo, I have yet to see anyone make a substantial amount of power that makes it worth doing the swap in the first place. You might gain 3-4hp but for the trouble you went thru and the clutter in your engine bay, just isnt worth it IMO.

I would dyno my car before but its not running right now and the 1g head alone should give me more than 3-4 hp. Especially since the 1g ports are twice the size than the 2g. This clutter that you speak of is 2 parts and there is alot of space to work with so I'm not to worried.

What you dont understand is you are already pretty much maxed out on the T25 the way you are right now... So you probably wont see much of an improvement. Also the bigger ports take more time to for air to be compressed in them...

I see what you mean about being maxed out. But that is the purpose of the cyclone to spool the turbo up faster but when both ports are opened up there will be more air flowing in. Even though i can't push anymore boost My high end power should improve just from the port size difference. But the reason im putting it on is for when i get a bigger turbo i will be able to spool faster. On that site the guy who has it installed with a 16g he makes 5 psi below 2500 rpms I don't. I plan to go bigger than the 16g so I will need the turbo to kick in as quick as possible. I know that have a better exhaust will help that but I need to do the timing belt anyway and its only an extra 300 bucks for the head to be machined so. I was already planning to get a 1g head put on so it set me back 85 for all of the parts

I'd also rather have 4 big ports to flow more air smoothly than 8 small ports and a plennum. Thats just another place for boost leaks!

I just had to quote this.... I agree on that 100% &

(gsxeclipse97) If you're going for something bigger than a 16G and you wan't to cut down on spool time then maybe you should try finding a new ceramic ball bearing Turbo, T3/T4 Hybrid or Custom T04E. Avoid a used one because once it goes they're basically done for.

I wouldn't buy a used turbo but im testing out the cyclone and seeing what it will do on the 2g motor also it will give me more highend from what i have now from you. I know what the 1g intake manifold feels like but i want to see what kind of power it will produce..

you dont understand. it doesnt matter right now what you do to let your engine take in more air. your turbo is still maxed out. the turbo can only flow so much air and the t2small is almost maxed out stock. adding the bigger ports and intake manifold will just lower your horsepower since you are adding more volume that needs filled and pressurized. the only benefit of a cyclone mani is the better spool and mpg on a street car. it actually flows 2cfm less at high rpms then a 1g manifold.

I know the cyclone flows less than the 1g manifold at higher rpms, but the will flow more than the 2g manifold will at higher rpms. And thats where i loose most of my power is about 5k and on. I know that is also that is turbo is really small and that is part of the problem... You said that adding more volume will make me loose power right. So if I put the 1g manifold on my car now i would loose more power than if i put the cyclone on because it has 4 big ports instead of the 8 smaller ones. In that case i would be better off wiht the cyclone. That is how its made spool the turbo faster and keep the topend power. What would 2cfm's be to your top end hp? So as small as this turbo is basicly soon as i step on the gas i should be at boost that would mean i would have no lag until i get a bigger turbo...

I know the cyclone flows less than the 1g manifold at higher rpms, but the will flow more than the 2g manifold will at higher rpms. And thats where i loose most of my power is about 5k and on. I know that is also that is turbo is really small and that is part of the problem...


No... Your turbo is you whole problem! There are plenty of people in the 300-400hp range with a all stock 2g motor (Intake mani, head and block) and I know that they dont lose power in the higher RPM range.

Get a different turbo if you want more power... The cyclone isnt going to get it for you!

Well do to some recent discoveries The cyclone project will have to wait. The head i had was way to warped to have machined. It would have cost me the same to buy a 6-bolt motor. But i dont have the money for the install right now so it will wait. But I did find out that im am getting a 3 angle valve job and getting a new exhaust system should be here in a couple of days... I checked out how much it would have cost to get a custom job done and he told me 450 for the catback portion. So i just got the apex for almost the same price i had to pay 60 for shipping but I will see how much the down pipe will cost me and go from there...

soooooooooooo basicly what everyones been tellin u is true

its a wast of time more money then nessacery when u could just put a 1g on it......

No I would to cost more money than i have to spend to have the head reshaped and i need to weld the thermostat housing for it to hook up to mine so. Im still going to do it I just don't have the funds right now to do it and i need my car back. Its the only one I have so it makes it kinda of hard to get around but i will get back to you guys on it I will have to wait for now though. I also need a 1g tb the jdm one not going to work at all

Ok big question is the cyclone worth buying for $50 on an 1 gen gsx, and what ecu do i need for it? and whats this stupid white canaster that i hear about?

I don't know if you noticed this or not but the last post was from 03-09-2005, and your not the original poster so could you please not revive old threads especially ones that you didn't start. Thanks and welcome to AF.
