B18Sleeper

Currently I have a B18c1 block with a spun bearing at the machine shop to get inspected and hot tanked. The crank is repairable but I prefer to find a better condition one or something else. So far they havent found any major problems with it. So once I get it back next wednesday from the shop I am going to start ordering and putting together this bottom end for 400hp and as all know people get boost happy and want more so I want this bottom end strong and have room for growth. These are my options

Option 1
ARP Main Studs
ARP Head Studs
Stock GSR Crank
Eagle H Beam Rods
JE Pistons 9:1
ACL Bearings

Option 2
ARP Main Studs
ARP Head Studs
Eagle Forged GSR Crank
Eagle H Beam Rods
JE Pistons 9:1
ACL Bearings

Option 3
ARP Main Studs
ARP Head Studs
LS Crank *I Know I need to worry about Oil Squirter clearance done*
Eagle H Beam Rods
JE Pistons 9:1
ACL Bearings

Plus I need a Water Pump and Oil Pump and I was thinking about running an ITR Water and Oil Pump. But thats up in the air right now. Let me know everyones opinions.

#3 youll love the extra umph from the longer stroke of the ls crank

B18Sleeper

Ok what if i go with the eagle forged stroker crank that makes the gsr the same stroke as the ls? cause i have been in many arguments over me just needing to build an ls if i don't want to use the gsr crank, but the gsr block has many more strengths in my mind that i like. thanks

I vote option 1 without the ARP main studs. I was going to do this with my build but was told it is not necessary......

Save that extra bit and put it towards a good turbo that will get you the extra low end power......

B18Sleeper

Well I already have the turbo for my motor, and why would u go with option 1? cause if i use a gsr crank i wont use the one in it i dont want the hassle of a crank with a spun bearing

spoolin turbo s

why go with a eagle crank when an ls crank has been proven to over a 1000 horsepower and eagle hasn't

B18Sleeper

Yes but is putting the LS crank with the machine work needed to work really worth it over the gsr crank? The reason I said a Eagle rod is its forged and seems to be worth it.

if you have a B18C1 block, you will NOT need an ITR waterpump and oil pump because they are the SAME

oh yeah btw stock honda cranks are forged too

oh and pick option 3

^^ yep Option 3 for the reasons listed above

B18Sleeper

well i dont have the water pump and the oil pump is shot. so i have to replace them either way. so just get a LS crank with LS rods and pistons or what

blinx9900

option 1 or 3, stay away from option 2 and you don't need the main studs unless there gonna help you sleep better at night...

B18Sleeper

well either way it goes i have to buy a gsr or ls crank all i got now is a bare block so which one? and do i need to run ls rods and pistons with this as well if i go with a ls crank

tony413

if your using an LS crank you MUST use LS rods

the pistons will not matter as long as they are the correct bore and have enough valve clearence if you decent to run a larger cam

iTrader: (1)

what about sleeves? since you have the block out already?b

B18Sleeper

so find a b18a/b crank order ls eagle rods then je pistons of the cr and bore i need? and when i order my acl bearings they must be ordered for a ls, but should anything else be ordered for the bottom out of out a LS? Like Crank Pully or anything like that.

tony413

a B-series crank pulley is a B-series crank pulley. just NEVER USE a ctr pulley it kills oil pumps .

all your bottom end bearings will be for B18A and B18B.

what cams do you plan on using ? that should help you pick a proper size piston, in respect to the fact that you will need the proper amount of valve clearence.

B18Sleeper

See I dont know I have been tryin to find the specs for CTR and ITR cams. But I can't find them. I don't really know much about any aftermarket cams for my car. Cause right now I am focusing fully on the bottom end cause I have it here to build the head is in use at the moment. I will be running a b16a2 head possibly skunk2 valvetrain, and either ITR or CTR cams. But cams is where i need help on specs. thanks

tony413

my rule of thumb is match heads to pistons.

b16 head = b16 pistons
gsr head = gsr pistons

thats just how i do. my way is in NO WAY a be all end all way of doing things.

if you need to just wait to buy pistons untill you are ready to assemble things

B18Sleeper

you mean wait till i am ready to assemble the entire motor before i order pistons? i know the head i will be using just not the cam. cause if i run a ls crank i know i will lose a little of my ability to rev farther so i dont know if a ctr or itr cam would work with my setup. cause i am planning on running a .57 trim .63a/r t3/to4 turbo with this as well.

anything under 500whp should not use a cam larger than a CTR/ITR or skunk2 tuner 1. theres no point and if you dont know the clearences dont take a chance. anyways get with the proper bore size B16 pistons.

B18Sleeper

well my first build is going for over 400hp. then as everyone knows i will want more and this car one day will be a strictly track car unless i get something else LOL. so run b16 cp pistons, b18b eagle rods, b18b crank, and b18b acl bearings. so are the itr and ctr specs about the same? cause i am running stock comp. and size valves just gettin a 3 angle valve job done.

tony413

1997-1999 CTR intake cams are bigger than the 00/01 ITR intake cams. the exhaust cams for all years are the same size. someone correct me if i made a mistake.

B18Sleeper

so wouldnt i want the bigger intake cam?

thats your decision not mine

B18Sleeper

thats the point FI forces so much air into the motor i think a bigger intake cam would help that air into the motor. altho i still have to worry about the valve overlay.
