OK, whell ive been searching alot on here and ive read alot of poeple say that the block will last and be reliable if you build it the right way. well i just got my ls vtec yesterday and im going to build it up for boost. the car its going in is a 88 crx hf.

Question is, what should i do to my motor for it to be done right. i want it setup for 10lbs of boost or less. i want to be in the low 13's.

any suggestions would be great, also any links that i can read about a build up.

well there a lot you can do to have a save ls/vtec
new forged pistons and rings
good forged rods
new bearings
blueprint and balance
new oil pump (endyn sell a good pump)
a good head (port-flow)
valve springs
this is just some of the stuff you can do theres a lot more..
just have it built by some that knows honda motors..

 

im having a friends friend build the block, i just have to tell him what i want. he gets parts for real cheap and he owns a machine shop. he isnt a honda mechanic but he has worked on them. so, from what i hear, i want everything forged. im just sure whats good for a turbo setup. or what kind of CR i need.

Thanks for the help.

thanks.

 

im running:

ls crank
eagle big bolt rods
arias 9:1 cr pistons
overbored to 81.5mm
acl bearings
itr water/oil pumps new from honda
all new gaskets
GE headstuds
Ge Ls/VTec kit

i DD a holset hx35 @ 7psi and occasionally 15 for that extra kick in the pants thru my stock exh...also have ran 15psi open 3" dp which rips the tires off thru 3rd..have driven it about 4500miles so far and everything is hold'n up just fine...rev'n to 8200...

at 15psi open dp im assuming its somewhere in the mid 300's

 

thanks, TTT. want to get as much info as i can

 

OEM BEARINGS.....nothing else....I repeat OEM bearings
resurface head, block, flywheel
ARP Head studs and rod bolts
type r/gsr oil pump
22T water pump
hoan the cylinder walls and new rings at least (might as well replace pistons since ur in there)
New timing belt

most important....don't rush the build, take your time and double check everything.
Also get it tuned once your up and running. Its a shame to see a good motor go to **** for nothing.

oh yea since your going turbo and only gonna boost up to 10 psi....get a block guard, if you wanna go all out get sleeved. The stock sleeves will hold up to 10 psi, but its a good idea to solve a potential problem while your in there.

 

whats your setup on ur ls/vtec...i like the numbers u have for hp and tq.. i myself have an ls/vtec hoping to be pushing as much as 200+ hp

 

You know for all you wizards out there I haven't heard one person tell this guy to get a MAIN GIRDLE! 8200?! Crank walk anyone? GE makes a good one of those also!

 

Thanks for the info,

i dont plan on rushing this build because nothing comes out good when its rushed. i have the whole winter to get this done plus the other thousand dollars worth of parts to put on this crx.

the problem is, is that i dont know what to tell the guy who is building my block. like what size pistons to get and if i want to bore it, sleeve it. i heard that there is something to do to the crank. i want to build the engine so that if i get a craving for more power i dont have to build the engine up again for more boost.

also im looking for parts for the head. only thing i have is cam gears. i want some good turbo cams, new valves and springs and whatever upgrade anyone is selling. let me know.

again thanks alot for sharing your knowledge.
