Oh I will for sure, I'm undecided on injector choice, I have Siemens 650's now and I hate the drivability of them and the idle quality but I can't afford new ID1000's so I'm gonna try and source a used set, and I'm doing everything off the wastegate. No boost solenoid/controller, so it's not like I can turn it down to 9 and say I lasted 100000 miles on 12psi lol
It's not "fake" VTEC. VTEC = Variable Valve Timing and Lift Electronic Control. Doesn't matter if it's two lobe or three lobe or any lobe. VTEC is VTEC. Also, it engages at 2200 RPMS on K24A1/4/6/8 and K20A3/Z2. Quoted from Wiki:
"VTEC was initially designed to increase the power output of an engine to 100 HP/litre or more while maintaining practicality for use in mass production vehicles. Some later variations of the system were designed solely to provide improvements in fuel efficiency."
And yes, it makes power faster below 6000RPMS because the profile for the secondary lobe is larger than the primary lobes on the three lobe VTEC engines.

Also flips over at 2200rpms....
All that was repostings that were posted almost 10 years ago when the 02-03 Si came out.

Why try to push the a3 to 350 whp and worry every time you go wot... well you have plans already if it blows so why not just test it out and prove us all wrong.. they just mention swaps cuz its gonna be more reliable than the a3..
if anyone were to attest to the struggles of the a3 i can testify to that.. i bought my car with 38k on it, drove it untuned with bolt ons to 50k, bought kpro.. beat on it some more .. turbo'd at 60k made 263 on 7psi, ran the car at 10psi on the street.. drove it half way across the country and back, took the turbo kit off at 75k, beat on it some more til 90k, and went vtec killer with six speed trans after that up til 106k when i pulled the motor, still strong, sold it to a friend who is gonna put it in a civic coupe. the motor is def strong in terms of taking a beating, i think the biggest thing on why people have seen soo many fuck ups is because of tuning. tuning makes everything legit and if you dont have an on point tune you're just gonna be motherfucking the motor even more and more.. seeing that the OP has been boosted for 4 years alone puts that talk to rest, and i've heard of stock blocks making excess of 380whp.. i'd say to give it a go, i know Dan is gonna try the same and see what happens
i went through a couple a3's when i was on a turbo setup.
it is a very underrated torquey motor when on boost. however the rods are a definite weakpoint when moving into the mid-300s. low 300hp and a safe tune though you should be good to go no worries.
wait, a3 parts are sub-par though...
I'm with the original poster...when I blow up my a3 I'll be doing a motor swap, just can't explain to the wife why I should swap the motor if it's still running fine. Good luck and keep us posted on how the car's running.
