ok ht i got a eg with a gsr in it b18c1 i took out the motor took the motor completly apart! head off oil pan pistons and rods i cleaned the block i replaced the water pump,oil pump rear main seal timing belt tensioner got all new oem gaskets everything oem honda parts i just got manley rods for it and cp pistons 81mm and arp head studs the cars not gonna be a daily but mabe take it out once a week to rip on it at the races a bit my goal is 500hp on e85 on boost so since i have it apart i want to know if i should sleeve it or not??? i see some ppl dont have issues on stock sleeves pushing them hard i dont plan on running at full boost all the time for 500hp just know i can use it if i have to let me know whats your opinion thanks for the help

 

why would you get 81mm pistons for a gsr motor?

 

^^ as opposed to 81.5mm?

If the block is honed, I don't see a huge issue.. Most guys will run 81.5, but if the block is good, what's the trouble?

OP: If you have the budget safe > sorry

Just my $0.02...

 

I would sleeve it if you got the cash for it

 

well its a stock block hasent been honed had factory pistons in it 81mm so i got 81s for it yah i was thinking the same to sleeve it just wanted to see what ppl think i mean i dont want to spend the $ to sleeve it if i can get away with it since cars not gonna drive that much since i got another car as a daily just need rip on it every once a while

 

there are people running a fair amount of power on stock blocks, more than what I'd think would be streetable. Just run it until you wear it out and then resleeve it.

 

thnx bump

 

you will be fine with e85 just tune, tune, tune

 

I would sleeve it. Safe > Sorry

 

ya people are pushin 4oo+ whp with stock sleeves easily. it can be done. people underestimate stock honda blocks, but if its apart, you have the money, why not sleeve it.

 

i was wondering the same thing? i am also running a t3/t4 b18b1 set up fully built but the funds are low for now, so was wondering on a daily driver how would it be, safe or not?

 

gringoteg's blown up quite a few stock gsr blocks usually cracking the sleeves, hes manking around 450whp so I would say def not a bad idea. plus you can go 84mm if you wanted and make a little more low end.
