getting ready to take my gsr out and re-build it. i was wondering what size bores u guys where going with. or just some sugestions in general about a re-build.

 

if you want to stay factory pistons 81mm and 81.5mm are your only choices, there is a pretty large aftermarket market for 84mm tho, have to get retuned tho

 

depends on your budget and goals overall. there are lots of oem pistons you can pick from that will give you a good cr if you'll be staying na. if you'll be boosting i'd get forged pistons for the added strength. also know that if you want a bore of 83mm+ you have to sleeve first. so take that into consideration.

 

i thought that you can bore to 86mm on stock sleeves? def not for boost but its possible i think

yea and it'll probably last 10 minutes. max bore on stock sleeves is 82mm and even then i would be cautious about pushing it hard.

 

^^Yup I would go no bigger then 81.5 but thats me.

 

yep, those two are right. MD on TI says go no bigger than 82 on stock sleeves, no bigger than 87 on aftermarket sleeves

 

yea im looking to spend around the 3500 area, for now im going to keep it all motor just for the reliabilty and stuff, but eventually i might boost it, who knows. But with a budget of around 3500 what are some of my options.

 

don't worry about making the bore bigger, what kinda power are you looking to put down

 

i dont know, i wanna keep it n/a for now so im trying to look at some of my options. So im not exactley sure what kinda power im looking for. What are some of you other guys running?

 

don't spend alot of cash on stuff for it to be NA if you plan on going boost. NA is not fast unless you drop alot of cash in it and it will be hell for a DD. this means there is no need to upgrade cams or header or intake. stock sleeves are safe up to 300-350hp depending on who you talk to. with that 3500 you can build a nice turbo setup. things you want to look for to make it reliable are forged pistons/rods and upgraded valvetrain.

 

okay, well yea i just bought a 98 gsr with 160k on it. The engine runs fine, i havent had any problems with it so far. but i dident wanna slap a turbo on a motor with 160k so i wasent sure if i should just stay n/a for reliability, witch i dident want to do, or just go boost. I only wana spend about 3500 though. I could possiby spend more if it is really needed but i wanted to see what some of you guys thought, and what were some setups you would suggest.

 

bumpp, any suggestions?

 

you could rebuild the motor to stock specs for fairly cheap if you are only going to add low boost (under 300hp) or you can sleeve it, forged itnernals, P&P head, upgrade valvetrain and cams, but that will get outta your price range
