That's one of the next steps... also a longer intake.

Finally got a picture of my valve cover. Had to clean it up first...

^ shit that's a lot of rubbing! The tooter would compliment that nicely.

[Bluevitz-rs]

Yeah a nice polished one :D

Really? The tooter adaptor gradually transitions to the slightly smaller stock yaris throttle body diameter from the larger Corolla diameter. since all of the other CNC information is exactly the same, it would be a simple matter to just make one with a straight through bore.

Is the Corolla throttle body also drive by wire? If so, is the electrical plug compatable?

[Bluevitz-rs]

Plug and Play.

Only issues I've read about are ppl needing to swap the chip on it from the one on the yaris. But others have just slapped it on, readjust the throttle plate idle screw and go.

That's awesome, blue!

If you do decide to polish and cut the nubs off, this is actually a Prius valve cover. I discovered the nubs on the rear are hollow and had a hole in it so had to replace it. The Prius uses those rear ones to hold something.

Can't be said enough, mad props for finishing the project in such a short time. Better than that asshat Holdener....

You can keep tossing parts at it, but until you can tune it you are not going to see the big gains.

this. and also, bolt-ons for such a low powered motor are kinda pointless imo... i'm new to the yaris and toyotas in general, but in honda land, if you wanna make big power, start with the head.

Thanks... I willingly chose to risk my own time and money just to find out for myself what would happen.

This is only a wild guess from reading the Holdener thread because I was really curious how that would all play out... but Richard's manifold might have yielded similar dyno results to mine which also produced an unsaleable product. That could have been why he pulled the plug on it even though he had $695 purchase orders for it.

That's about 80% true. If you get the 1ZZ TB whose part number ends in 031, you won't need to do the chip swap, just have the ECU re-learn the intake volume. At worst, you'll have a slightly higher idle until the engine warms up. This is what I'm dealing with, and don't mind, but I know thebarber took his off because of the same problem.

[4/20 NEVER FORGET]

From reading I've done on this forum, a couple of threads have expressed you need a Corolla TB ending in 030 otherwise you need to do a chip swap. (mine is from a 2005) I bought one and it has a noticeably larger air path than the stock TB.

The only other difference I notice on the TB is that the coolant lines are at different angles than the Yaris TB, but that is an easy fix.

I wish we could nail down this information. I have no plans to install the TB on the stock manifold, I'm waiting until I get a new intake manifold. I'm excited to see what MicroImage is going to come up with, but my current plan is to buy a xB weapon-r and have a local fabricator design a new plenum and a 1zz TB flange. The weapon-r manifold is just a starting point really.

[tooter]

It's nice to know that I might have inspired others to explore on their own. The Weapon R Xb manifold you want is presently selling for $469 including shipping on ebay... but I haven't yet been able to find any actual dyno run results even though Weapon R claims their intake manifold makes 15 to 30 horsepower in a normally aspirated engine.

[suckerface]

4/20 is right, it's part number 22030-0D030 that I got. Personally, I completely bypassed the coolant lines.

Hit up eBay or a junk yard now and then. You'll probably be better off at the junk yard as on eBay they're all around $150.

Can't wait for the MI manifold! It's going to be ported for the 1ZZ TB, correct?
