Ls Vtec Build

[CHERRYOKC11]

I hope this is the right section, if not I hope someone can move it.

I'm starting to build Ls Vtec I already have an Ls Block B18B1 and B16A head and ITR S80 Tranny. I have tried to find as much info as I can. I know I need to run an oil line or buy a conversion kit. I have been looking at the Golden Eagle kit. I already have the GSR timing belt, water pump, and oil pump. Also got a GSR crank. I know I need head studs, rod bolts, gaskets, etc. I read I can use 92 95 civic ex si wiring harness. I'm still confused about pistons. i found this on another forum:

"Pistons from any B16 because LS pistons do not have large enough valve reliefs for VTEC intake valves. Forged pistons would be better, but if you can afford them B16 pistons will work well."

I read that CTR pistons don't fit right because of how domed they were. I almost ordered some tonight. If anyone knows about pistons, please share the info. I will post pics within the next few days. Please post links or personal experiences. Thanks ahead of time!

alot of people go with b16 or itr pistons. i read that the p30( b16) pistons have built in oil-pockets to help cool and protect the pistons skirt and wrist. I was gonna build a lsv a few years back and i was gonna go with the itr you can find either and many other optins for pistons and parts on just about any site. here are a few if you have not already been to them INLINEFOUR.COM - Mon.~Sat. 9:30am~6:30pm PST - 11400 Knott Street, Garden Grove, CA 92841 Specializing in JDM-USDM Engines & Parts...hmotorsonline.com Engine Internals | Pistons, rods, camshafts, valvetrain, etc.... | Password JDM you can find just about anything you need for the ls vtec on those sites and there reputible shops to. and with the b16 head you can use a 92-35 civic ex harness. i would also think about getting a 2 layer head gasket to bump the compression a little. not sure how much your gonna build it but some nice cams and valve train would make that thing rip....

here is some ls v threads to ill post more if i find any
ITR head and B18b block
LS vtec ?????
LS/Vtec oil squriters?

Thanks for all the help!

i used the itr pistons...good clearance, but i'm using the gsr head and a cometic gasket

[firefightermdc]

just went with itr's cause they're everywhere and am very happy with the #'s...16xwhp i forget if it was 168 or 169whp and 151lb ft of torque to the wheels..picks up and launches hard!

[CHERRYOKC11]

thanks alot. i couldnt decide on the p30s or itrs. ordering them right now

[CHERRYOKC11]

I ordered the ITRs and ordering a CTR crank pulley this weekend. I should have some pics up soon. Which rods would I use? ls? itr?

[CHERRYOKC11]

havent gotten the crank pulley but picked up a d16z6 wiring harness and decided to stick with the ls crank and get rid of the gsr one. took the head off and sold and pulled the tranny. will post pics tomorrow

edit:never mind no camera today

[wcki11a]

I know people using ctr pistons in ls block with gsr Head it run great but the cr is high and they only use 93 octane

[CHERRYOKC11]

cant decide to keep the itr or go p30.....

bro turbocharged would have been better/cheaper..

the b18 non vtec engines are the strongest out there and they can hold a shitload of psi
