tooter's next manifold adventure...

Bypassing the coolant flow through the throttle body, probably marginal lower intake air temp.

Guess i should get this spacer rather than a exhaust header, more practical to have the same torque at lower rpms (everyday driving RPM).

My guess is Id save a little gas by being able to be in 5th doing 25mph in Residential area. Also probably can stay in 5th and still have passing torque on freeway.

**So this spacer moves the same profile curve to the left. And the tooter manifold with 1ZZ TB just gives higher max numbers. Between those two, the spacer is better for a normal day to day use car?

I don't know... that TRD header in the For Sale section is a really good deal . And from looking at it's design with the slightly longer runners, it would also add bottom end torque. I just don't know how much.

The spacer makes it easy to short shift at 2,000 rpm around town without lugging the engine. It's also really easy to take off from a standing start without a lot of clutch slipping or revs. It generally makes normal everyday driving more pleasant.

Now that the ECU has settled in and the car is all gassed up, I'm ready to log some mileage readings. I'll let you know the results, for better or for worse.

For regular transportation driving... the tooter I.V spacer beats the hell out of the tooter manifold!

I'm going to experiment with the tooter et manifold by taking off the top of the plenum, and see if I can lengthen the runners from the inside.
