I have a 98 gsr shortblock which im planning on rebuilding. I bought this block a few moths ago with the pistons/rods taken out. The crankshaft is still installed and obvious the oil pan is removed. How much am I looking to spend to have the crank bearings, rod bearings replaced and also changing the pistons rings. Is all this necessary? If so which brand should I use and again how much should this work cost? Im not to familiar with internal engine work so this is why I need a heads up.

 

if i were rebuilding a gs-r block that had all its internals, i'd be looking at about $450-$500 in parts for EVERYTHING. rings, bearings, gaskets, new pistons, the whole kit 'n kaboodle. if it didn't have rods to begin with, add maybe $100 for used ones or $200 for reconditioned ones, but used should be fine. and i already included pistons in the $500, so that's $600 w/ no labor, just parts. labor at a shop will probably be $1500+. do it yourself.

 

Is it a difficult task to do it myself? I am good with tools but never attempted to use a torque wrench but I do have a friend or 2 that worked on engines before. Should I buy OEM parts or aftermarket?

 

if you have the money, definitely go OEM. at least for the bearings, go OEM. everything else is open to debate, but IMO, head gasket and bearings = OEM. some people will say ACL bearings or something, but at the end of the day,
1) Hondas have select-fit bearings, and only Honda makes the perfectly-sized bearing for each individual journal, and
2) Honda makes the best parts for Hondas, period.

 

I would like to go oem as well but its a little expensive. So let me get this straight, I would need to replace the following parts for a nice shortblock rebuild.

New:

crank bearings

rod bearings

piston rings

hone sleeves

head gasket

oil pan gasket

Is there anything else I would need besides help installing this crap?

 

little things like thrust washers, oil pan gasket, head gasket; just get a kit.

oh yeah, and get oversized pistons and bore the block to fit. pistons will fit like new, rather than have a crappy fit, and besides, you gain displacement.

 

I have a friend that works in a mechanic shop so maybe I should buy it through him. Helms book would show step by step on how to remove/install this rebuild kit?

 

yup. helms = . make sure you get new pistons oversized and bore the block to fit.

 

not to threadjack this,but im interested in the same situation on a 94 gsr,do they make oem oversized p72,or p73 pistons?

yes. any piston can be had from Honda or from the aftermarket in stock size and in oversize, usually in a couple different larger sizes.

 

Honda has oversized pistons/rings for any bore? If thats the case maybe I should buy after market pistons/rings and rods as well. I plan on boosting on my motor in the near future. If I were to buy the je pistons and eagle rods, I believe the combo will come with rod bearings and piston rings correct? I can then just buy stock bearings for the crank, hone the block, and buy arp head studs and call it a day. The cost might be slightly a little more but for boosting I should go that route. What you think?

 

Since youre starting from scratch, why not build it for power? Forged connecting rods and pistons would be a great start to any project. If you look, you can pick up parts for cheap. The slogan of my project so far has been "powered by e-bay"

 

I just might have to go that route. If I were to buy the piston/rod set ups, it still should be the same spec when it comes to using the torque wrench correct? I would like to do this asap, im already talking to a friend that wants to get his hands dirty. boosting my gsr ek will be sweet

 

all ARP bolts come with their own specs. as bor bearings, don't use aftermarket. Honda for rods and crank mains

 

Dont get me wrong, friends are friends, but sometimes you dont want to trust things like building your car to them, unless they have done it many times before. The best thing I can suggest is do your homework and research and talk to real mechanics to figure out whats best for you and how to do things. Its just that a friend can disappear whey you have a connecting rod sticking out through your block. Plus, if all goes well, you can say: "I did that."
