THROTTLE BODY SWAP NO CEL!!!! - Toyota Yaris Forums

kou · 06-20-2010, 05:19 PM

So i did the swap without getting a cel ever. THANK YOU jkuchta for the info.I ordered a new intake manifold, a yaris and a corrola throttle body.Step one was to fill in all the cavaties on the manifold with JB weld then port the opening as much as i could. swapped the chips over on the throttle bodies and removed the epoxy from the idle adjustment screw,then switched everthing over, did a pre adjustment on the idle screw and made a paper gasket which is siliconed in place.

how much were you able to open up the stock manifold?

kou · 06-20-2010, 05:36 PM

I ported the top to about 2.4" then i tappered down as much as i could, the plastic is thinner the further you go.the factory opening is 1.75".

not too shabby

notice a difference then?

Nice and clean. Very good job!

I opted for a custom adapter instead of porting the IM. How much did the IM cost? Just curious.

There is a difference at all rpms but more after 2250rpms.more engine power with the ac on which is a big plus. my ASStermater says more tourqe than hp.definetly worth the $250 in total spent.

should be the same...only different item on the 2nz is the pistons/rods (and therefore the displacement)?

nicely done. I've always thought that this mod, done carefully, is a good one.

Thanks, definitely can't rush this one.

d1nzfe · 06-21-2010, 10:26 AM

what do u fill up those 'holes' with? the purpose to 'strengthen' the frame for porting?

Nexus1155 · 06-21-2010, 11:34 AM

NICE WORK, very good thinking on how to get it done, as long as you let the JBWeld cure and it stays that is a nice for DIYers. Just hope nothing ever happens where a chunk might come off of that and go into the engine

kou · 06-21-2010, 12:49 PM

Thanks Nexus.I am not to worried about the JB weld it's now a solid ring.Any way if something did happen engines are pretty cheap.

I used JBweld the slow curing type.Mainly to make a flat mating surface for the throttle body.Because of the intake manifold design after porting you have to put JBweld on the inside to get a smoother slope.

Nexus1155 · 06-22-2010, 12:33 PM

Drive a full cycle, usually 80miles on most ECU's and let us know if there are any CEL then? I would love to do this.

YarisSedan · 06-22-2010, 01:06 PM

Wow very nice. If your gona do something do it right. For the price of the intake manifold its not that bad.
