Ok, what exactly do I need to have an ls/vtec motor that runs well? I was thinking about doing it this week, until I began to realize how expensive it might be. I already am running on a LS motor, and was going to do this in preperation for my final project of ls/vtec turbo set up. Besides the b16 head, what else do I need for the car to run well and fast????

Cost:
Here are the parts you need for a great setup..
B18b/a block.... $600
B18C1 Head...... $1000 VERY hard to get..
ITR pistons..... $250
ALL new bearings.. $300
Block assembly..... $400
Balance crank...... $200
Head gasket....... $55
Re-tap oil line... $100
Skunk2 intake manifold $320
Type-R throttle body.. $250
Wire harness... $200
Shift linkage... $150
ECU.. GSR.... $300
GS-R tranny... $750
Fuel Regulator + Guage $175 installed.
Cam Gears... $250 installed.
Type-R cams.. $450 installed.
Valve Adjustment.. $50
Motor installation... $800
Intake manifold gasket..$25
Oil/filter.. $15
Axles... $200
Header...4-1 $297
Cold are intake.. $225
New timing belt. $80
New oil pump... $150
New water pump... $150
Dyno Tuning.. $100
270 CC Injectors.. $200 or used prelude..$100
Apex V-AFC controller..$320
6 puck clutch $350
Resurface flywheel.... $30
and there you have it....a setup with mostly all Honda parts...total bill for that: about...$8542 Now if you were to substitute pistons, rods, and port/polish the head. Then you have a REAL beast on your hands...ready to take on just about anything but motorcycles on the street. That's a FULLY built, no skimping motor you have there. Nobody said going all-motor and being super fast is cheap. That is why the low rating on cost.

 

hes right.. ive spent 2700 on a built block.. 650 on a bare ITR head, 900 for port and polishing, 335 on a JDM ITR header, and i have intake mani ($250), TB($250), and internals for the head (1800 for JUN3) to go, oh and dist($??) and wiring harness... then injectors, clutch and flywheel ($600), hondata 3 (i think $650). so yeah, its a lot of money and time

i think some of those prices are off but it should get you a good idea of what
you need.
i'd personally wouldn't get a b18c1 head....
but either a b16 or a b18c5 head...
http://www.alaniztechnologies.com/marcharticle.html <~b16 head flows better.

supposedly the b16 head is exactly the same as the type r(b18c5) head...but
the type r head is ported a lil more?

i would also get the b16 tranny or type r tranny. closer gears than the gsr
tranny...supposedly an LS with a b16 tranny is supposed to give a gsr
either a run for it's money...or even beat it. lots of variables to consider...
but the closer gearing on the b16 or type r tranny would only benefit you.

hope i helped.

 

Don't I need new pistons?....Won't the LS pistons have too low of a compression ratio to make good power? And, I don't want to BUILD my motor just yet....I just want to get it done....I want to know the BARE minimum, because I was planing on doing turbo this comimg wniter. Thanks.

 

u can get pistons, rods, rings for about 1000 or less..

 

why do you wanna bump up the compression if you're gonna go turbo...?

 

yeah from what i know, the b16 is almost identical to the c5...the c1 has a smaller combustion chamber than the two...c5 is minimally ported from the factory, but minimally is very much the key

all in all, it really depends on what you want to do with the setup...if you plan on going all motor, go for high compression pistons like r's and crower or skunk cams
if you plan on going turbo, stay low compression like 9:1 pistons and sleeve the block, stock cams will be fine for any boost not abnormally high

 

Yeah, LS/VTEC is a lot more involved than most think. As for most things, you're paying for what you get.

I'd say screw LS/VTEC, turbo is less expesive.

 

I made my decision....I was planning on doing ls/vtec w/ high compression for the time being, then turbo later, (and lower compression)...I just decided I am gonig to do it all at once.....ls/vtec turbo....thanks.
