sorry didt got back to the topic..
@mani1
if you have been through his whole car..then said change was gear box and vitara pistons..but yet lets take them as stock
all setups along with dave r running high internals just around 380sss
and Gonzales video here i posted way back

car was for sale for 14k USD....thats expensive then 2005 Porsche in USA
then fueling such car with 116octane fuel.... still u think it was stock
He claims it...and only will tell if some 1 buy it from him
otherwise when 2.4L Na F1 cars can do 750bhp and rev 19k
and way back 1.5 turbo doing over 1300bhp....in F1
then Money can do anything ......for sure these G13bs and G15s or vtec or 4efte can do that ....but all that matter is how much u can tune and maintain
My g15 after few races need alot of care...and you are talking about 400bhp....
Man like dave have been having issue dealing with a good gear box to hold just 350hp
