ls/vtec swap

[rony]

whats required and how much will it run, a friend of mine has a... i belive 95 ls and was wondering how to make it fast... i heared a while back from the hybrids about turbo ls/vtec's haulin' ass... just curious... he has a decent amount of cash to spend on mods, but i don't know much about teg's... any help will be appreciated

Basic list of what is needed for the LS/VTEC motor
buildup. Maximum performance gains will
not be realized unless you bump up the compression ratio
by meaning of higher compression pistons or other parts.

1. A non-VTEC block(B18A/B).
2.A complete VTEC head from any
B'series DOHC. Must included VTEC
distributor, cams, valve cover, intake
manifold, & throttle body, along with all
other part on the head.
3.A B18A/B timing belt(non-VTEC belt) or
VTEC T-belt to match with VTEC water pump(DOHC)
4.B series DOHC VTEC head bolts(95+ GSR)
5. A VTEC ECU, or an RPM activator switch to activate the VTEC solenoid.
6.B18A/B non-VTEC headgasket.(for hight C/R use only single middle layer)
7.A threaded flat head hex screw to fill the oil feed hole on the
VTEC head or have an machine shop welded and resurface or both.




Recommmend part list to consider:

1 DOHC VTEC oil pump(DOHC B'series)
A DOHC VTEC water pump(will need DOHC timing belt)
B'series VTEC piston with higher C/R with valve relief cuts
Shot peen Rods
ARP rods bolts & head bolts
ITR, CTR or aftr mkt. cams
ITR intake manifold
(when using B16A or B18C5 heads only)
Stiffen springs for that XXXtra rev
Reprogrammed VTEC ECU(PR3, PR30, P28)
(will need to run knock sensor on some ecu)

Here are a few steps & pictures to illustrate the setups.

plagiarizing, it always makes someone sound like they know what they are talking about. haha

nah man just messing w/ you. you pretty much summed it all up. but you forgot one thing man. so important too, i can't believe you left it out: the fuzzy dice.

as far as price goes, expect anywhere from 2000-2500. i got mine done w/ my boy. i payed 2gs and got a B16 head w/ all the trimings, an ITR intake manifold, STR cam seal and blockguard. plus i got the Field's VTEC controller too. not bad, but don't expect to be as lucky as i was.

2-2.5G's? shit where'd you buy your parts? b16 head=~400-800 (intake manifold included) depending on where you buy it, ecu=~150-200, don't know about all the other crap, but i don't think the little stuff (headgasket, bolts, etc) will add up to 1.5K. this installation isn't that hard, you should be able to do it yourself. i'd strongly recommend a b16 tranny to take advtange of the high rpm power you'll be getting (another 700-800 bucks).

Dont waste your money the LS engine has a poor rod ratio so you really cant rev high and since you cant rev high you cant take advantage of VTEC. Just go turbo its easier, more reliable, and offers more power. BTW turbo and and VTEC really dont mix due to valve overlap once VTEC activates the larger cams lobes. (AKA VTEC kicks in). The LS engine has lower compression and taller gears........which are good for turbo.
