You're right... the engine pulls strong right up to the top now!

Congrats on getting those numbers. You've worked hard for it! I'm glad it all worked out in the end, 110 whp isn't bad at all for a car that was rated 108 hp at the crank, with only bolt-ons!

Now I really can't wait to get a manifold and stick on this 1ZZ throttle body I have.

Just be sure to break off the epoxy and turn out that little idle screw about one turn before you even install your 1ZZ. It should work just fine as long as the butterfly can close enough for a nice slow smooth stable idle.

I'm so pleased how this has all worked out. The combination of the larger manifold and larger throttle body added up to doing more than each component could do alone.

...and I'm still not done yet. I have some other experiments I'm going to be trying out in the near future.
