So I grenaded the **** outta my ls/vtec and it's time for another. I'm at a crossroad now and don't know which crank to go with.

Basically I have a b18a long block to work with so i have the full rotating assembly.

I also have a spare gsr crank and mains w/the mbsp

I have a set of cp 11.5:1s to throw in
And ill buy eagle h beams for which ever crank i go with.

The head will be stock (no port/polish) obd0 b16 skunk2 valves/springs/retainers/stage 2 cams/cam gears (still need to buy the spings/valves)

So right now I need to buy main studs, rods and bearings for the bottom end but I need to decide what crank I want. What do you guys think? I have lots of other stuff for this motor as well

Aebs intake mani/68mm tb
arp head studs
aem fuel rail/fpr/marshall gauge
jdm itr 4-1 for now.. im borrowing it until i can afford something nice

I want to break 200whp but I'm not gonan ahve money to get the head worked ):

I'm leaning towards and ls crank right now but I really like the idea of a mbsp but I won't have the $ to get a golden eagle one for my ls setup.

 

i'd go with the ls crank

 

without the ls crank its not ls/vtec

 

use the ls crank

it's still gonan be an ls block.. which requires the ls/vtec line.

 

yes ut the rod to stroke ratio given by the ls crank is what makes it "ls/vtec" otherwise its just a poor mans type r i believe.

 

ya you have a point.. i tink im gonna stick with the ls crank anyways.. itll give me more displacement and compression

 

87 &gt; 89.

FALSE!

 

Personal pref.

 

Just givin ya **** man.

 

 

so why do you say gsr?

 

either or. just stick with the LS so you dont have to get the block align bore to fit the gsr crank

haha ya i was kinda thinking that but I have seen some really sweet deals on gsr rods so sweet that id still be saving if i buy these rods and pay for the block align bore.

gsr main bearings are the same as ls right? the rods bearings are the different ones...

OK now I know most people don't like the 89mm cranks, but what's is bad about them? The R/S ratio? That's easily fixed.

Dart B20 Block 226MM deck height
151mm Length rods
LS Crank
Type-R head

An Effective 2L Motor w/ a R/S of 1.70 Not too shabby
