Vtec E madness!!!!
okay well guys i got the deal of the century. i picked up a 95 eg coupe EX 5 speed for 300.00! perfect interior, exterior juts needs a quater panel and thats it.its got ur standard rice intake,header,exhaust. the reason i got it so cheap bc the guy put the shift linkage in wrong and thought the tranny was garbage.somebody has done a swap into it, that being a d15Z1. i guess from what ive read its the economy version and vtec kicks in at 2500 rpms.thats doo doo, so what im askin is what do i have to do to make it like run like a d16z6? i dont know what ecu it has in it, but what would i need to put in there for vtec to kick higher? i already have a single cam turbo kit that i got brand new for 300.00 and a set of free dsm 450's courtesy of the dumbass people at my local junkyard for not checkin my toolbox 
so basically my goal is to have a high 13 sec single cam slam for less than a 1000.00!! thanks for the help in advance guys

That particular head casting has small valves, small intake ports, and a small chamber. You'd need another cyl head. But it's not that easy. The stock pistons in a z1 have a HUGE dish in them because the chamber is so small (cc-wise). What this means is that when you put on a z6 head, your compression is so low it's barely useable.
Long story short, get a used z6/d15b/sohc-vtec zc and boost that. The power potential is greater. And then, you could sell me the cam/rocker assembly for 20 bucks.

Re: Vtec E madness!!!!
well for one when i said vtec to kick higher i meant around 5500 rpms, not 2500. and not bullshiting u, i have a daily driver 11 sec twin turbo mustang, so NO i dont know how that vtecE bullshit works; so enlighten me vtecE master. and how but i just boost the ---- out of it and not go through all the crap of changing heads or motors. i got less into a running car than most of the people have into there turbo/injectors on here so it really doesnt matter to me. its gonna be a shitbeater thats good on gas thats all i care about.if i wanna go fast ill drive my mustang. thanks

Re: Vtec E madness!!!!
If you want vtec-e to "kick" higher then you don't get it.
It's not your conventional vtec where it switches to a slightly more aggressive cam profile upon activation. It switches from 12 valve mode to 16 valve mode. If you want more power keep it on all the time (which ricers try to do with regular vtec, it's much different)
Personally I have my vtec-e engage at 2600 rpm under hi-throttle, and never under lo-throttle. It gives me 45 mpg on the highway and when I open up the throttle the extra power is there. You have a z1 head though which I've *heard* has crappy flow. I use a y5 head which I have no complaints about on my turbo setup at all. Runs **** and gets me awesome gas mileage.
