More like your friend is either a shite driver/you're a good one, or maybe his engine is sick as a dog. An I/H/E SOHC VTEC will not keep pace with a stock B16A.


I have both engines in different cars. Done CAI and headers on the SOHC VTEC and at some point I'll do a hi-flow cat and cat-back, but I'll do it on the cheap and only because I enjoy it.
The B16A is a D-killer pretty much and worth your penny several times over by comparison.


For you I'd consider some cheap Ebay extractors but other than I/H/E don't mod your D any further - no ECU. Personally I love the D for what it is, but it's not really supposed to be a 'fast' engine (yes obviously you can turbo it) and to be honest you can spend all the money you want but ultimately you can't turn crap into gold at the end of the day.
