thinking of getting an intake soon so....

i go to one place and they say that no one makes one for the n/a supra... i go to another and they sell an hks intake and an akimoto intake... and i have a magazine that put apexi power intake in the n/a... does anyone know anything about these intakes... which one is the best??? or should i just put one of the k and n drop in air filters? i don't really want to get the hks intake because i saw at mkiv.com that the filtering is very poor (that picture of the towel was really dirty)... i don't want that junk getting sucked into my engine... and i heard akimoto filters are k and n filters... i've also heard that the akimoto intakes actually decrease power on some other cars but i don't know if it's true... the magazine that put the apex power intake showed only a 3hp gain...

another of my concerns is for that guy with the msb supra that did shaving to his afm... if i did this would i still be able to pass smog test? how does the sound level and performance change? and is there a wrong way to do this? what is the correct way to do it? and is there any downsides to doing this?

any help would be appreciated... thanks

to my knowledge it does not affect emissions at all. if you put a drop in filter and take the cover off the air box you will notice a sound diff. at WOT. after porting the MAF i immediatly noticed that the throttle responce was much more responsive. To do the job right be sure to take out the "black box" and DO NOT touch the sensor. other than that just dont shave it off so much you go through the housing.

I got the HKS intake a few weeks ago, and so far it has done great. Dusty of MVPmotorsports reccomended it, and i've heard really good things about him, so i trust him. I noticed the biggest difference at higher RPMS where our cars usually tend to lose power. Now it keeps on pulling.

I have the Apexi Filter and i like it quite a bit i believe it does help a little bit. As far as sound if you keep the stock intake piping there wont be a change from what i could tell. The other thing is about the Apexi filter is it rated best on that list you were talking about on www.mkiv.com and it showed a gain in horsepower AT THE WHEELS on that magazine you read so that shows you it works. If you want an improvement in sound i would suggest replacing the stock intake piping. I went to the local "import shop" and he sold me a intake pipe for what i believe is a new Accord and hacksawed of the end that didnt fit (easy to do on these metal intakes) then get a breather filter for the Bigger vacuum hose going into the back of the valve cover there and i was set. The sound is alot cooler when you have a straight flowing pipe.

thanks for the feedback

i am planning to do this to the 5-speed. are you guys auto or 5-speed?

thomsoncharm and 93msb, where do you actually feel the most power, low rpms or high rpms or throughout the whole range?

with the air filter box not there, does more dirt get into the engine bay?

has anyone else ported their maf? does anyone know for sure that this doesn't mess with emissions? i am still kind of confused on how to do it. it will probably be easier for me to understand once i take everything off. but i will ask again before i try it. by the way, what tools do i need to do it?

how about gas mileage? same?

sorry for all the questions... i just want the most info i can get before i do anything... you guys understand

thanks for the help guys

*wish* i notice a difference on i guess both i mostly noticed the sound though and a little more pickup on both ends high and low. I guess most being the top end. As far as having the the box off and gettin more dirt in the engine bay i havent noticed anything. If you have any other questions just let me know man ill try to answer em as best as i can as far as that MAF stuff i have no idea about that stuff.

Basically power comes on after 4500rpm and lasts pretty much to redline, its a dog before that rpm. Noise is increased after ~5,000rpm. BTW this is for an auto

Hi,
I just finnished porting my MAF a few days ago. Also, I am now running without the cover for the airbox with a K+N filter. I didn't do a great job porting the MAF because I didn't have a lot of time, but I will really finish the job later when I don't have so much schoolwork to do. Well, I really liked the results of the porting. The car feels stronger past 5K rpm's. Also, the sound is great. I'm not sure that this is all just in my head, and other factors could have affected what I thought was a stronger top end too (it was a cooler day). I really didn't notice that big of a difference in throttle response though. It just seemed to pull harder at the redline (especially in second).

Also, I'd like to know how many of you have removed the honey-comb grating that is at the front of your MAF's. I removed mine a long time ago, and the car seems stronger without it. I think its just for noise, since the car is quite a bit louder at WOT now. Any thoughts on this.

U know how in our cars (stock), when they hit 4K RPM, they kind of set you back a little, but they die off at 5K. well now w/ the intake it pulls a little harder at 4k, and at 5k it sets you back again and pulls hard to redline. I'm also running it w/ a no muffler w/ welded pipes which made a huge difference on low-end. So w/ the exhaust giving low-end, and intake giving high-end, i have a pretty good set up. I'm going to take it to the dyno this week to get some #'s, and tune my S-AFC and see what that does w/ the intake and exhaust.

We see more HKS SMF intakes than any others on cars & so far we have seen no actual real world proof of any damage what so ever from the filtering they do (or don't do). Sticking a vacuum cleaner to an intake & shoving it in a pile of dirt is not a very real world test IMO. I would recommend it for any NA or TT supra (along with the Max Air system for the TT).

And one more thing, the HKS are the cheapest which doesn't hurt. Unless you include the Apex filter which I have had on backorder since LAST August (yes, in the year 2000).

Hey ThomsonCharm,
Where did you get that air intake piping ?
That looks real nice !! I would definitely like to
get one of those puppies...

I was thinking the same thing!

what kind of plug wires are those?
Cam Gears?
what else you got in there?

thanks

· #15 · Sep 19, 2001

Hey guys those are actually the stock cam gears i just forgot to put my cover back on and the wires are Magnecore they are really good wires i put them on for my ignition system which i decided to have the mechanic do after getting the spark plug socket stuck in there you need a Snap on Tool for like 45 dollars if you wanna do it no hassle. And the intake pipe is from a Honda Accord i just went up to the local import shop with my old intake piping and he gave me an Accord one that i hacksawed the end off of. The vacuum hose in the back can be covered with what is called a breather (that lil air filter thing toward the back of my engine) and then run the other house into an adapter and they to the nipple on the piping. The grammets (cool red things connecting it to throttle body and MAF thingee) are from Thermaflex they got come cool stuff its silicon so it will stay shiny for quite a while. Hope this helped you guys out.

how much did all this cost you? can you give a detailed description on how you "hacksawed" the ends off? did you do the mod yourself? thanks

What about the above for 87-92 Turbo which is supposed to fit our cars with longer bolts? Is there a complete Apexi kit or just filter? Iceman kit?

ThomsonCharm

· #18 · Oct 1, 2001

money,
The whole intake thing cost me hmmm well it was like $30 or so for the piping and around $150 i think for the Apexi air filter kit and the breather in the back is like $5 and the nice silicon connectors there i got from Therma flex for like $8 or so i think. The pipe is from an Accord and it is longer then it needs to be so i put it in the car and kinda compared how long it needed to be to fit the MAF with the filter on the end correctly. Then i marked a line across the pipe of where it needed to be hacked off (there was originally two nipples on the pipe and the first one was hacked off with the piece of pipe i cut). So i just cut off the excess pipe and was left with one nipple for the one vacuum hose and the second THICKER vacuum hose you put the breather on. So yes i did the mod myself, it is simple all you need is to hacksaw the piece you dont need off and it should fit just fine. Then connect it to the MAF with the filter on it and your all set.
Hope this helped.

ThomsonCharm, thanks for the reply...

any changes in performance? what did you have on the intake side before this mod? stock, drop in, cone?
