Bought my first Celica GTS

[thebarber]

celica is a 1 piece manifold, the xrs is a 2 piece. its part of the reason the xrs dyno's about 10whp more than the celica.

angle of TB is different, however

Interesting.....I’m intrigued. What is the solution for the different throttle angle? XRS or aftermarket intake maybe?

Congrats on the fun car! The Celica should be a hoot to play around with.. Looking forward to seeing what you do with it.

Haha, unfortunately that’s not possible due to the bell housing mounts used in the Celica chassis. You have to use the 1zz/2zz C56 or C60 bell housing that have the starter at 10:00 vs the 2zr/1nz at 9:00

After doing a good amount of research on this I’ve found that the difference in power numbers was due to changes in how the power is measured. Everyone on all of the Toyota forums mentions this and how the dyno numbers from all 2zz cars is about the same.
