my car is a L15 the project started out just trying to do something different and over the yrs other things have come up so i havent had the means to really tune it to its full potential. i have heard very positive numbers for the jazz but at the end of the day its still a 1.5l sohc. it is a good drive and u canfeel the bost kick in but atm my set up is abit laggy bcz of the fmic size and length of piping.

as kungfu said, it us personal preferance and circumsances which will determine the power gain and durability on the drive chain and engine, additionally driving style and use.

understandably i have 2 young children and i'm a conservative driver which is why i have it at low boost.

the degree you choose to modify ur car is up to how much of an enthusiest you really are. money wise, if i wanted performance on a bugdet, i would've bought a r33 if i wanted big numbers.
