Better Acceleration????

yea thats what i meant with the vtech with forced induction, i just did not go into detail. there is too much overlaping in order for the car to have forced induction. yea if you got less aggressive cams plus lowered the compression, the car would deff. be a beast.

i was comparing the motors stock vs. stock. thats not fair to change the crap in the k20, thats hurting my argument, lol.

Get a 1993 + Honda del Sol with the d16z6 (1.6L) motor. It's 125hp Stock with VTEC around 5200-5800 rpms and it seems to help the turbo. A guy on my old site used to have one, and he was throwing down 433whp (SOHC engine btw), and in a light car thats amazing! And it would have cost less then what my p5 did. I personally loved honda engines, once i figured out what VTEC was and how it works, the engines are a breeze to work with, and can withstand a beating.

your talking about vtec from 1993. vtec in the k20 motors are completely different. k20 motors call it i-vtec. the difference is, on old vtec, at a certain rpm, the extra lobes on the camshaft will be activiated and therefore open up the intake and exhaust valves up alot more and therefore raising the lifts on the camshaft.

i-vtec, or new vtec, changes the cam angle on the entire camshaft. therefore, that allows more lift in duration to take place, and since the cam angle is changing, it will allow the cams to overlap creating more power.

old vtec is alot easy to tune and take advantage of with forced induction, but i-vtec is a different story

i-vtec still has the cam lobe change. Its just had variable valve timing included.

variable valve timing, if CORRECTLY tuned for a turbo application could be quite handy..... but yeah, MoTeC or Hondata is going to be about the only solutions to being able to control these.....

Either way... K20 (unfotunatly) smacks the FSDE in just about every way you could possibly think up ... damned hondas....

btw...12's with minimal mods? don't think so. not even the b5 s4 with chip. only thing left on the s4 was a turbo swap. far from minimal. a4 2.0? naw. you have a b5 right? 1.8t? slow as balls even with chip. turbo swap isn't minimal. a4 2.slow(8). slow...s/c isn't minimal either.

Well I have stock internals I run a gt28r, a rather small turbo at 24psi. I also utilize meth injection. There are handful of bolt on chipped S4's in the 12's on the B5 chassis. I think my work is minimal. I feel big work is gt30r and bigger, built internals, worked tranny and gutted interior......But everyone has their ideas as to what is mild and what isn't. I've built cars much crazier than this that have hit low 10's....I love the car to death however the power just doesn't do it for me. I'm not wowed by it I guess. Also the 2.8 is a slow car even with the S/C.......It's not a VR6, just a V6 that you can't even get tuning for. Also, an A6 with a 3.2? That's almost a 4,000lbs car....I would hope you could pull on it. Just realize that Audi has many versions of each car generally with at least 3 engine choices, even 4 in many cases.......You could have race a base 180 quattro TT which is indeed slow as balls. A 225 is different, a 3.2 is different.......Not trying to preach the Audi thing, just realize there are many options and that street racing is for those who aren't mature enough to keep it on a track.
