T Montague's 2zr swap - '08 m/t sedan some extra info

[CrankyOldMan]

Yeah, kind of a bummer. If I had the 1.5L it would be just over 2000. Not sure if the loss of HP is worth the lower competition weight. Makes it all the more interesting though to look at higher redline or different cam profiles for the 2ZR, so I'm very interested to see what you come up with on yours.

To stay in the 1.5L bracket, have you ever thought of Frankesteining a 1NZ with FXE internals, to increase the compression ratio to 13:1 and having forged rods. Also the FTE's redline is 8K, with that information, you can safely get the rev limit moved to maybe 7500 in the 1NZ, and put that in you HB? And then use the xB1's transmission, which has a final drive ratio of 4.31 vice the Yaris' 3.72. The gear ratio for 1st to 5th and reverse are all the same.

There's some restrictions on internals and compression ratios that I haven't delved too deeply into, mostly because that's outside the scope of the build for now. It has a C60 gearbox in it now, not sure what final drive offhand. My DD hatch has the 4.3 final drive in it (and a custom configuration of OEM gear sets) and it's a real detriment on long tracks because I lose a LOT of top end speed.

Wait, wasn't this thread about someone else's car? =P

OOPS! I had to look at who the OP is, sorry I got you two top notchers confused...

Restriction on internal swap to change compression ratio? Where's can I look for the handbook for these kinds of events? How much do you guys invest into this? I might dive deeper into this hobby once I retire from the military.

I'll start a thread about my other questions.

On with the weight reduction thread.
