i hv searced n found people with ls crank n rods in gsr block and some encountered problem with the ls crank hitting the oil squitters..and few said not all gsr squitters are the same where in this case they wont have that problem. so im wondering if this problem will occur in b16b block... if yes, how do i go about modifying them (or find the right gsr oil squitter,but what year?) or do i just block it off and how do i block it?..

 

ttt...

 

if they hit you can just bend them out of the way or plug them

Yup, if we're working with forged pistons we normally just plug them off. You can actually weld up the block if you want but it's easier (if you have the clearance) to cut the "nozzle" portion of the squirter off and TIG is shut (bolting it back in just as it normally would be minus the jet).

 

yeah..i'll try the bending option.if doesnt work,then ill plug them off..

 

bump...thinking about doing the same thing. LS crank and rods in a GSR block with either ctr pistons or aftermarket pistons. what is the displacement on that combo?

 

At std. bore you'll displace just what an LS motor does (~1.83L) at 0.25mm over you gain about 5/100ths of a L. It also drops your rod ratio to that of an LS, from 1.58:1 to 1.54.

is that good or bad?

is there any advantages to putting a LS crank in a GSR?

some people think it is bad.. but someone told me that it is not entirely true about what most people think about rod ratio...

 

whats the CR like with CTR pistons?

 

its going to be like 13 compression

 

Yea, that change in rod ratio isn't a huge deal and is nothing to even really worry about, I just figured I'd mention it. As for swapping an LS crank into a GSR block, you're really not going to make much more power and the increase in displacement isn't too dramatic. I personally think it's a waste of time and money. The real way to make more power is to start with a B20 bottom end and either leave it (even completely stock bottom ends reving to ~8k do just fine), throw some forged pistons in one, or sleeve your GSR block (which is what I would do) with aftermarket pistons (this option however is the most expensive).

 

well thats true if i have a gsr block..but in this case i have a b16b block which is why i go with the ls crank route... the b16b short block cost me around USD$500.there is lack of gsr shortblock where i live..

 

Yea, then that's a cool upgrade. Sorry when I wrote my last post I was just thinking you had a B18C to start with.

 

thats ok..u prolly got that thru some else posted having gsr.lol... anyway,im going to resleeve my block but will be done by local machine shop here..not in the states.i'll see how gud they do it..sending it to the states just to xpensiv for me..unless they do it really bad then i will hv to

 

the only problem with oil squirters in the b-vtec block with the ls crank is the actual bolt that holds the squirter to the block touches the counterweights on the crank

 

where do you live.....care to trade cranks with me?

haha

haha...are u for real?? i live in Brunei..its in south east asia..land of cheap VTECs.. we just dont hve the technologies like in the States to make them as quick as u all do.... i didnt buy the LS crank n rods by themself..i had to buy the whole long block and cost me USD$380..

so do u think i could like shave off a lil bit of the bolts to giv a lil clearance?

 

that's what i've done in the past
