STL - what's going to be hot?

[Rabbit07]

For those of you who would like non USDM engines. Please write letters. these letters are heard and could sway the decisions one way or the other based on quantity. As I said before there are those of use for and against it and we need a strong business case. We also need thoughts on how to police it. Remember boys and girls, STU is a National class with RunOffs eligibilty. That means it must be able to be policed.

I would be for non usdm motors for everyone. I know atleast in the Honda world JDM motors have more availability,lower price, and better performance than USDM.

I'm sure this would help out others wanting to be in the class.


I have a question about using a non vtec 1.8, what if my power levels are way off compared to the 1.8 vtec motors? Assuming both motors are built to their fullest potential within rules specs?

Non vtec motor gets a slight drop in weight?

Just curious.

...what if my power levels are way off compared to the 1.8 vtec motors? ... Non vtec motor gets a slight drop in weight?

Negative, not at this time. However, theoretically, VTEC in and of itself is of no value to power, given both engines are allowed the same limits on compression and valve lift. The differences will come down solely to differences in head design, intake manifold, and throttle body.

Thanks Greg, I know vtec is not the difference in power but the head flow, intake manifold, and superior flow compared to the non vtec motors head which is where a lot of the power difference comes from.

I won't know until I finish my non vtec build within current specs and with the better torque numbers the non vtec motor makes, maybe it will balance out. The one advantage the non vtec motor has is the fact you can run a decent cam with the .425 lift max which is where the vtec motors are already close to stock at around ~.417 intake.


I would assume there are other manufacturers with similar situations.

I wrote mine in August. #2428. Looks to have been tabled for the most part. Do I need to start writing once a month?
