i think smoothing it out is a damn good idea, but make sure the valve still closes properly

i have found a way to help with this mod but it requires a bit more elbow grease. or should i say degreaser.
oh and i found grinding stones for drills and dremmels at a dollar store and the came in sets of 5. i think it would be worth the trip to find the deal i did.

Be sure to clean the part thouroughly after your done. You dont want any shavings flying into your engine!

I cleaned off all the grease before I started with cleanup solvent. After it was done, I hit it with the garden hose.

I cleaned with throttle body cleaner before and after grinding. It really cuts through the grime nicely.

I want to take off my intake plenum and throttle body to clean them out thoroughly. Will I need to get new gaskets for them if I do? Also, does anyone know where that adjustment screw with the yellow paint on it is supposed to be set? After I took that part off for cleaning and polishing, I noticed that the valve was not closing flush and that that screw adjusted the amount that the valve moved. Is the valve supposed to be closed flush or is it supposed to have a partial gap when fully activated?

You will need a new gasket if you remove your entire intake.

That screw you speak of does adjust the clearance on the acis valve and it should close without any gaps. Just turn it till the valve closes flush.

i more or less just cleaned mine ... about how much should you grind around it? i look off about 1/2 mm. i think more of what i see for performance is from cleaning mine but then agian i dont think i ground out enought. could we get a close picture of the ground out area?

Marvelicious · 08-05-2004, 01:00 PM

I took a sharpie and made a line next to the butterfly with it in the closed position. Then I knew I could grind up to the line with no problem... Ground a radius with that as my limit. MUCH more than 1/2 mm.

***2wickedtoyz*** · 08-05-2004, 01:13 PM

sorry dude but my digi sucks. just make the edges as round as possible. that way you can get better flow.

***Your Uncle Moe*** · 08-05-2004, 01:48 PM

Oh now, for all the people who have done this, do you feel an difference in performance? Because if you dont then this whole thread is useless.

***2wickedtoyz*** · 08-05-2004, 02:05 PM

have you tried it? when i go to nopi i'll be hitting the dyno and we'll see what my car has improved in. if i gain tq then that's cool if i gain hp that's good also if i gain both that's great. but you do know sometimes not all mods give you "seat of your pants" performance. like it was said before due to the production and the little time and money to do this to every car toyota makes it wasn't cost effective. the ports on the intake manifold don't even match to the heads or the plenum even the tb doesn't match to the plenum. so tell me fixing these "problems" wont help in performance? if not someone better tell all the people who race and build motors to stop since it's not worth doing.

Marvelicious · 08-05-2004, 05:32 PM

Exactly. I've heard it stated (no I don't remember where) that anything less than like 7hp is imperceptable to most people. Does that mean that it isn't worth having? For an hour's work? FREE horsepower

Besisdes it did make a subtle but perceptable difference, so 7hp? And as 'toyz pointed out on the first page, his wife noticed the difference without being told about it. That pretty much proves to me that the gains are real and not wishful thinking.

Yet again I say this is EASY and WORTH DOING!

wontonjohnny · 08-05-2004, 07:27 PM

doesnt the ACIS close at 4000 rpm??

im pretty sure on my car it closes, so porting it shouldnt do shiet...

most likely you guys who have done this mod do your butt dyno tests right after completing the mod, right???

i think the gain is there but not from grinding, its from test driving a cold engine... my car has always pulled the hardest on the first or second WOT pull

next time your out testing see if it still kicks after 15 mins of driving...

but putting a CAI will indeed help inhance the kick
