well I'm looking into starting my first engine build so I just wanted some info on what setup should i use I going to buy a b18b1 in about a week. So what mods would benefit me the most as far as all motor non vtec goes. I was thinking on do ITR pistons, shot peened rods, crower cams, skunk2 IM, cam gears, 3inch intake piping, dc sports header, and buddy club spec 2. keep in mind this will be a track/weekend warrior but i still want it daily drivable. Oh yeah it will be going in a crx or ej1 coupe. any info will be greatly appreciated.

The ITR pistons will need to be modified to fit on the LS rods, I personally think shot peening the rods is a waste of money; I would get ARP rod bolts though, and if you go with higher compression pistons go with Crower 404’s. For the header you’ll want something with a 2.5-inch collector like the JDM 4-1, you’ll also need some tuning. Also, if you haven’t bought the motor yet…why not go with a B20?

That was goin to be my next question. what if I got a b20 instaed what would I need to do it for a weekend warrior.

wrong, they do not need to be..

if you plan on doing an ls all motor.. that is totally cool, alot of people are going to tell you its a waste of time and money but if its something you wanna do and be different..

For you bottom end, I would say do ARP rod bolts, take them to the machine shop and have them installed and resized.. (They will know what to do)

Have the ITR or B16 pistons whatever you want, intalled too.

For your head, I would say get some springs and retainers, and the crower 404's will work well too..

Get something to tune with, like an obd1 ls ecu..

b20sedan said it pretty well, do some searching, there are afew threads on here about some non-v all motor builds, just depends how much money your willing to spend

all motor ls is a waste of time and money either turbo it or do ls vtec i have an ls integra and im goin for ls vtec all motor my friend had one with stock bottom end and some bolt ons in a si coup and he hit a 14.1 at the track

Well, the rods need to be shaved like 1 mm or so to fit the ITR pistons.

Guess it depends on who ya ask. And what ya plan on using it for.

if your goal is 170-190hp range all motor i say go for it. it might be hard at times but with a good plan it shouldnt be a problem.

i believe bearsEK got a post awhile back on a LS making good power.

I don't think so man, The itr and b16 have the exact same cast, and in my ls.vtec I used b16 pistons on ls rods with no modifications, the only thing i needed to do was have the big ends of the rods resized for the ARP rod bolts, no mods to the pistons.

are we talking about oem itr pistons here? i was always under the impression that ls rods need modding to fit real oem itr pistons..

Yeah, I've heard that B16 pistons will work without modification, but for ITR pistons the rods will need to be modified.

you dont know what your talking about. your not doing anyone any favors by making **** up. even a monkey can take an ITR piston try and put it on a LS rod and see it wont fit. ITR/CTR/GSR pistons are not interchangable with LS/B16 pistons.

really you know this because youve tried? i doubt it. youd be supprised how little i spent on my motor and im making ~180hp/150tq

like people already said ls all motor is a good REALLY reliable REALLY easy route to take if you want to make 150-180hp. if you want more than that then you are better off goin vtec. between b19coupe, myself, and bearsek i think weve proven nonvtecs as a cheap reliable alternative.

b20sedan

He speaks the truth...can you really argue with cams that cost $280.00 (what I paid for my 403's brand new from a local shop in AZ)?? An AEM ITR cold air costs around $200-$250.

man expletive all this go all motor gsr, cuz your about to spend the money the money you would if you went straight to gsr, i learn the hard way, i rebuil bottom end up, 92 ls head on a 90 bottom end, b16 piston aem cam shaft, even pully's, well no crt pully's, intake not really anything, megan head 4-1, staight 2 to 2 1/2 inch piping cat. and then after a while i did a 94 gsr head to my 90 bottom end and did ls vtech, tune correctly and my rods snaped after a while like about 13 to 14 runs on the track and um daily driving....go gsr and save the cash... all motor gsr...

man go for it bro,im gonna start my allmotorls build when i get some good money aka job lol

I posted in another thread with a similar topic..

I understand PR3 OR P30 pistons are the way to go in an all motor LS b18a/b BUT I'm confused since some say the rods need modification and some say the piston-vavle clearance is an issue with higher comp. pistons
(I'm personally looking to use "oem" pistons ie. ctr)

what's true?

i say go for an all motor ls...if i were you this is the combo that i would use:
-p30 pistons
-shot peened ls rods w/oversize rod bolts
-crower 404 cams and valvetrain
-skunk2 or blox manifold w/68mm TB
-gsr trans w/lsd
-and a good tune

and if you get tired of the ls you can always put a vtec head for more compression and vtec.

hope that helps...

for you people who never done ls-vtec with itr pistons, don't talk about it. You DON'T need to shave down the rods. I just got done building my ls-v and I didn't have to shave anything down. I got my pistons stright from honda if your asking.

CW96

Everyone is suggesting LS/VTEC when the topic is [all motor LS].

Is no modification needed for just LS (B18a/b head) or a VTEC setup?

the only time you have to shave the rod is for ctr pistons. the area where the rod has to fit is narrower. ctr rods are narrow at the top. and the only other rod that will fit ctr pistons without shaving is gsr. So the answer is you do not have to shave the ls rods to fit itr pistons. only on ctr pistons.

Here you go, cost effective build, I spent between $2500 and $3000 on this set up.
