Hi All,

After some help - not sure which of these engines to get - the TQR or the XXL9 with the 14.5 crank

Seen that the xxl9 has higher top speed but is this the only difference - and i guess that comes at expense of bottom end?

Would really appreciate some insight + what max tuned pipe would be best to go with it....

Thanks

The TQR should be slightly faster with more top end. If you are looking for reliability, the XXL9 with 14.5 crankshaft should be better in this department. I am not too familiar with MAX tuned pipe but NOVA 2015 or 2052 should mate them nicely.
