Can any of you guys with access to TIS provide information on Bore & Stroke for the IS350?


-Thanks

 

I don't have access to TIS, but I do have access to google!

Bore and stroke on the IS350 is 3.70x3.27 or 94mm x 83mm if you prefer (compression is 11.8:1 if you're curious)

 

GOOGLE!!

Thanks a lot! I'm busy working on a project and doing a lot of research for other stuff and for some reason google never came to my mind for this issue.

 

Just FYI you know you can pay 10 bucks to have access to TIS for a day right?

 

Yes, I know. I worked at Toyota. I just needed this info. Usually, I don't need TIS so, I don't bother to pay.

 

Anyone know the rod ratio for the is350 (even better would be ConRod length & Crank radius)? OR. Do you know if TIS will have it (Although, I doubt it)? Maybe it's time to join up.

 

Radius is 1/2 stroke. Main journals are 61mm and rod journals are 53mm. TIS does not give a rod length specification, only a twist specification. Typical Toyota is 1.65 rod ratio, but without measuring, that's just a SWAG.

 

Thank you.

I guess 1.65 should be good enough. And it should knock of a few HP from my analysis...
