Who makes a good, true CAI. Not a WAI, but a real CAI. Also, is it worth it? I have heard on a lot of cylinder engines, most of the time a CAI on a N/A engine kills the air velocity and it is better to leave the stock setup on there. And, is there anything I can get to replace the small MAF on the car? I remember having one of those on my 626 and i always wanted to replace it with something else. Any info would be great, thanks.

I bought a cone filter and fabricated my own CAI out of aluminum flashing and heat insulation material. The more intrepid amon us have actually cut holes in the wheel well and located the filter outside the engine compartment. My opinion (and you know what opinions are like) is that if you do find a CAI package, its going to be overpriced and probably not work well for what you want. Invest in a good K&N filter and an adapter, if you need it and build the CAI yourself.

Yeah, it's not very difficult.

Is the CAI for the T2 ever going to be done?

Not enough intersest to make it financially sound.

I've offered group buy situations in the past with little response. I get 2-3 people. That isn't enough for me to fabricate the parts. I don't make much on them when you calculate all the direct and indirect costs involved in making them. If you can get a medium sized group together PM me for details and we can take it from there. 5+ people willing to put down cash.

Was this a true CAI? How much lag was there with the long tubing?but like you said, there is no interest, I dont even know 5 people with rx7s let alone t2s.

The CAI re-design I did made it uni-sex so N/a and TII will be the same model. This was as true of a CAI as you can get. The Filter sits up where the bumper is so it gets a nice and large shot of fresh air from the opening. There wasn't any lag because the AFM is already the biggest restriction in your car and the PIPE is 3" which is much larger than the inlet to the AFM.

I can also make them in 2.5" size(more practical for N/a's) which will increase response and need less cost and fabrication(you save money)

Like I said. If ANYONE can get a group of five people or more that will PUT DOWN the money I WILL make them for you. Otherwise its a waste of my time. I make more money selling used parts.

Cost-wise...what would we be looking at for about 5 or so people?

It depends on what each person wants. Its difficult to say. I can get inexpensive K&N filters($35ish) 3"/2.5" Aluminum, Regular Steel, SS. All these combo's were available but noone shows up with cash. For just the CAI itself in SS I think I could do 150+s/h Aluminum is higher and regular steel is a little(very little) lower. 3" is more expensive than 2.5" obviously. Then if you want silicone couplers or rubber and worm gear clamps or T-bolt.

Its a large variety of options that affect price. But you could be out the door with a CAI for around 150. Full on silicone 3" T bolt Aluminum pipe might be closer to 200.

Well i bought a cheap ebay intake for another car and a POS fake "ram air"system . ill be piping the cone filter from the stock location and then running the ram air thingy (its a sheild for the filter and a section of tubing to a rectangular inlet) ill be piping straight downand under the car. I figure while moving this is the best location since i cant put a hole through my radiator. is there anyway to bypass the MAF or wire it open without horrible side effects?

Old pics of my setup, easy to do.

I have the same cai as above. It seemed to give a great boost in power. Not any noticeable lag either.

got any pics, Im just interested in the difference of routing from the turbo instead of the TB

I couldnt find the pic, either that or I didnt have my true CAI on long enough to take a pic. But I used to have my K&N filter sitting directly in the bumber mouth. You'd be suprised at how dirty the filter would get just in a couple of days. My reaction to having the cone right in the bumber, in the direct path of the incoming air, not worth it. It felt no different from when I had the filter just in the engine bay. Theroretically, the air going to the filter is much cooler than the engine bay air, but it didnt feel like it made a significant difference in hp.

Yes I did cut a hole to get the 3 inch pipe down there. I would never do it again, for a possible 2 or 3 hp.

I would compare this mod to the TB mod. It is theoretically better, but on an NA, you might get 1 or 2 hp at higher rpms. On a TII, maybe 5 at most, if your lucky. www.1300cc.com has an great write up on a CAI for a TII, but the guy also installed a FMIC, E-fan, TID, and Rad ducting...so there is no solid hp gains from just the intake, on THAT WRITEUP.

If all that doesnt make any sense to anyone, just know that even the slightest drizzle caused an engine check light.
