Bottom End for Boost....What do you guys think?
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.

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......

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
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.

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
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
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.
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.

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
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
b16 head = b16 pistons
gsr head = gsr pistons

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.

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.

thats your decision not mine
thats your decision not mine
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.
