Please help with Cyclone

[Pure92TSi]

I would say so. I know the one dejon tool makes you get gains of around 30-45 hp. And the price on it is much less than a BJ or other ones. I haven't seen any of the ebay ones but i would say they would work just fine and better than the cyclone intake manifold.

 

[Spydergst97]

Well the one i seen on ebay looks just like the awd talon car i seen at nopi i mean they look identical. i didn't know it gave out that much hp!! cool thanx

Do your research, there are tons of threads on the cyclone intake manifold.

The cyclone gives you better low end torque and spool up IF you have the right chip in your ecu. The chip runs about $130. If you don't already have a cyclone intake just go buy a custom intake.

FWIW, the JDM cyclone motors do have upped compression to 8.5 instead of 7.8. That is about all.

 

[gsxeclipse97]

From what ive read in other places they come with forged internals. That what i was told the evo motors there came with.

So i just bought a '91 TSi AWD with a JDM cyclone engine in it. I was wondering what the difference was between this engine the stock engine in my '91 TSi FWD . Also the timing belt slipped. Wondering who makes good replacement heads. The clutch is also bad and was wondering of a good clutch to put in to handle moderate mods. Thanks.

 

[Jeff_Ferrara]

excedy makes great clutch setupss... stock heads flow great.. most guys on here are probly all about act though

 

[95blackGsTurbo]

I prefer the SBR 3500 clutch myself but have been really pondering trying one of Fidanza's new clutch's. With the quality of there flywheels, I would imagine there clutch's would be pretty good too. Exedy also makes good clutch's as well as ACT. For moderate mods, there are a lot of clutches that will get you by. As far as replacement heads I would just buy a new set of valve's for your head and put them in. It will be a lot cheaper than finding a head. Slowboy also has some good replacement heads though if you are really looking for one as well. www.slowboyracing.com

I am really in a twist. I have been reading through some of the other threads and have myself scratching out and rewriting my mods list like crazy. I need so guidance. My goal is over 350whp for my fwd 91 gst. I have been thinking of getting a cyclone motor, doing a solid rebuild, then work with the tuning. After reading some threads, I figured I could just stay with some beat-up usdm motor and rebuild. With the turbo situation, I don't know what way to go. I am on a bit of a budget and don't want to spend a whole lot having to a bunch of work changing things out. I have been thinking of the evo3 16g but I don't know. I really don't know what to do with the boost controller or fuel computer either. There is just so many choices. I already posted a thread about the maf. I also don't know what to do for a datalogger. Does the DTEC system double as a datalogger? I dont think it does. Well guys and gals. Reply with your opinions and give me a little direction to work with.

Sounds to me you don't have the knowledge for what you are trying to accomplish. Take baby steps. You can't just throw stuff on your car and wish for 350 hp. Unless of course you pay someone who does know what they are doin to build it up for you. If you are tryin to learn by yourself, spend time on here reading through all our tech articles. Even though I know a decent amount of things for the 4g63t iI still read everyday I can to learn something I didn't know before. It helps out greatly. O and there is no cyclone motor. JDM motors have a cyclone intake manifold(which you can read bout if you search for it) but it is a 4g63t just like the rest of them.

 

[nightracer91]

Thanx. That is what I needed. Some Direction and information. I'll keep looking through the tech articles trying to gain more knowledge of it all. Actually a buddy of mine just drop in a jdm motor in his talon. He didn't use the intake manifold off the jdm though. Would it ge wise to get it off of him or is the stock mani fine?

 

[importboost]

Well see the JDM intake manifold has a two runner system that is controlled by the computer. US spec computers can't control them without a chip. So its a better idea to use a US spec intake IMO. I have one, got ride of my JDM one. Its pretty complicated system that i dont want to type it all out . Just search for it and read.

 

[nightracer91]

Okay, that's cool. Thanx for your help.

So i bought a cyclone intake mani. i heared it is suppost to give extra torq. and it's going on a 2g head the port on the 2g head was ported to match the intake but my question is does anyone have instruction on hooking it up to work correctly?
Also i have a JDM throttle body is that basiclly same hook up as a 1g throttle body in a 2g?

 

[kottyking]

Not true. The cyclone mani flows less up top. The 1g usdm intake mani is the highest flowing stock. The cyclone must be set up correctly w/ butterfly valves to get it to work. It's for low end torque, it uses "dual runners". I'd ditch it and buy another one.

 

[L'ville]

i know the 1g flows more but i am running this on a 2g head in a 2g car and i really would like to run the cyclone and i have heared of people running it correctly it's one of thoes 50-50 debate thing half people seem to like the idea and half don't....

 

[alex]

Take that manifold and sell it. Trust me. Your only hurting yourself, or the person your selling it to. I've had bad expeirence with those manis.

 

[pinder91]

The Cyclone is a GREAT manifold for people who don't have high horse, top-end monsters... it's all about the city driving with a Cyclone.

A friend of mine had one working properly on his car and it was amazing. It sounds like everyone that complains about them never had them working properly in the first place.

As soon as I find the right deal on a complete one, I'm picking it up.

 

[94awdcoupe]

My good friend has one on his mirage and he is making 567awhp & 511awtq. He is making over 500whp till 7600 rpms so whoever says this manifold is junk just doesnt know how to set it up properly. We have several cars down here using them with great success.

 

[94awdcoupe]

He also post under my name from time to time so when I see him again, I will have him chime with his thoughts.

 

[alex]

Just sharing my past expeirence with you.

 

[L'ville]

yeah i heared that they are a good upgreat but i am not sure how to hook it up i have a idea but i really don't want to just try it like that i really would like some imput on the installation.

 

[pinder91]

Send a PM to Agent11br... I drove his car once it was working correctly. Gotta love the low-end torque.

 

[DROOPY209]

I have one laying around in my garage from the JDM 4g63t I bought back in 2002.
The first time I read the instructions on it, it sounded kinda complicated to get it to work.

From the hundreds of posts that I have read about it, it helps your low end torque basically. If you plan on driving it on the street mostly, and want better low-end torque, the cyclone intake mani will work very well for you once its set up correctly.

How is the cyclone intake mani bad for top end? I've read many posts that said that their top end felt the same after installing the cyclone intake. All that air still has to go somehere, into the cylinder head.

Once I find a good tutorial and a free day, I'm gunna install my cyclone intake mani.

You forgot that it makes min 520whp from 4800-7800rpm. I have overlays of other cars making 565-575 on sc61 or 35r with sheetmetal intakes. From the graph you cannot tell which car is using a sheetmetal and which is a cyclone. I am still on a low compression 7.7/1 block. I will be swapping in a high compression block this year. I expect it to make well over 600whp on the cyclone. The current numbers where made on 93/alky at 33-34psi.

Also what you dont see on a dyno graph is the cyclone 35r spools 1000 rpm faster than a sheetmetal in 1st and 2nd gear. And 5th gear torque on the highway is just downright nuts. I wouldn't part with a cyclone from my setup for nothing. They just plain rock.

Does it work on small turbos? local here swapped in cyclone on his 14b car and his topend went from 150mph to 165mph with no other changes.

Exactly 4G63-gst.....If set up correctly, it is VERY beneficial, especially on a street car.
I think the main point that deters people away from the cyclone intake is the installation, wiring, and tuning of the cyclone mani.

Everything has its costs and time.
