Hi hotscar
My brother had one absolutely brilliant car never let him down he had a corolla gti 16v before.
I don`t know what your brothers like, but mine slightly modified it
lowered the point the vtec came in and changed the exhaust made a huge difference.
Fantastic to drive when he let me for a big car comfy and not to bad on juice.
hope this helps
Hi mate
just out of interest, what did he set the VTEC point at? I ask as I used to be pretty active in the Honda clubs a few yrs ago when I had my CRX VTEC.
I spent a fair wedge moddin it. I tested various VTEC points with the DTA remappable ECU I had & it was a total waste of time lowering below 5k rpm as all it did was actually bog the car down. Even by adding more fuel lower down the rev range to go with lower VTEC point it still didn't help.
I've heard a lot of people fitting VTEC controllers & just lowering the VTEC to 3.5k rpm. You get the benefit of the nice VTEC growl much earlier but it does sod all for performance. If owt in hinders it. The engine needs to be higher up the rev range for it to make use of the VTEC & extra fuel
Any proper tuning company with good experience with VTEC will same the same. Originally John Noble Motorsport, as in, Noble M12 GTO etc etc mapped my CRX.
VTEC was set where it is by Honda so you could cruise on the motorway without having to have the VTEC cam lobes screaming their nuts off at you & wasting all your fuel
Oh & if you're wondering my CRX didn't just have the usual filter & exhaust mods. It had a 1.8 VTEC block with oversized JDM ITR pistons, reworked crank, 1.6VTEC ported head with ITR cams, valves/followers, JUN Ti retainers & springs, cam gears, inlet manifold, bored out throttle body, 2.2VTEC injectors, etc etc etc
In the end i'd spent roughly £20k & it was 236bhp. Would have cost less but i'd bought & tried various cams, exhausts, chips etc etc
