Nope, I use Honda S2000 '99 engine, 1st F20C gen engine, and stock chassis as I wanted to have a premium version of the F20C S2000
and this engine has enough torque in mid range, even though it's peaky at 296 ft lb/10200 rpm, but half of those are available from mid rpm. Sitting at 580HP with sports exhaust, non break in, with break in and racing exhaust, should be at least 600+HP.
Rolling in 3rd gear at 60mph/5000rpm it can pull nicely, so it's not bad, considering it has tall gearing - 3rd maxed out at just over 130mph
It also has VTEC kick yo !!
from around 6000-8000rpm then turbo kick from 8000 to 12000rpm
Just joking....
Using Spoon engine is bad IMO, it already has extreme tuning, so it's not very flexible with further tuning, using a stock engine opens more possibility, like this build, I can up the power to 700+HP by reducing rpm redline to 10000rpm and have more mid range torque as well running full boost. It's a balance of engine and turbo tuning selection
EDIT : Done
Honda S2000 F20C TT, stock chassis, F20C engine from S2000 '99, custom engine + turbo setup 600+HP,
Will be on share soon, and the next project is "going back to the past and make it the fastest"
