Im planning on rebuilding my 96 gsr motor im not sure of the miles but when i researched car fax it was listed at around 160,000 miles. When i got the motor it had alot of oil leaks around the cam cap, valve cover which i replaced but then i realized there was more leaks between the head and the block, and between the oil pan and the block. I replaced the oil pan and gasket now, but im not sure as what to do. I was told that i should just replaced the head gasket. But i was thinking i might as well do a engine rebuild. Does any one know what exactly i will need? I just wanna have zero miles and built up alittle

 

A good start would be new bearings (rod and main) and new piston rings along with new misc seals (main seal, cam seals, etc)

This is what I did to my '95 gsr engine before it went into my CRX.

Don't forget a new oil pump, water pump, headgasket, and timing belt.

I'm probably forgetting something, but hopefully others will chime in.

 

remove the head from the block if its inside the car just leave the block and tranny there. remove the oilpan after draining all the oil, remove the oil pickup and the oil windage tray, then remove the crank girdle (some of the mains might have to be removed in the process as long as the end ones are still on then you wont have a problem the crank will stay in place just make sure you keep everything in order.

then proceed to remove the rod bolts and take the caps off, again remember where everything came off from if you have to label everything. then gently push the rods from the bottom until they pop up from the top. you want to clean up the cyl's and any extra oil or residue. go to honda and pick up from oem piston rings (have a shop put them on or learn since you need a ring compressor) and then head on over to acura and pick up new bearings for your mains and for your rods, notice on all the rods and mains you removed they have a color stripe on them you want to replace them all with the proper color bearing.

then its basically putting everything back in place, the bearings pop back in place you just have to be very careful its a delicate prosedure have some one knowledgable help. and you need to have a quality tourque rench and have a helms to know all the proper tq specs. once everything is back on you can put the pan back on use some honda bond, you will need a new headgasket (lil copper spray on there) and get a new top end gasket set, new valve cover gasket and the lil grommets for the valve cover and just use honda bond here and there

 

Chameleon is right, but dont forget to take your rotating assembly to get balanced if you get new pistons and/or rods

 

Anyone have a ballpark figure of how much it would be to rebuild a GSR engine?

 

if you have some one do it, around 1500...its about $500 to put it all back together alone by a pro. and thats a damn good deal...

while your at it, might as well throw in an ls crank, ls rods, and ITR pistons

 

I was thinking more along the lines of ctr pistons stock bore size what exactly would i need for the rebuild? And would i need to resleeve my block?

Cause i was planning on
new valves
pistons
piston rings
rods
thats all i know im still learning on building
i just wanna build it right so i wont have problems

 

if you are getting new pistons, you may want to consider getting oversized piston/rings since you mentioned the last recorded mileage was 160k. you could skip this if your walls are still in good condition, its just a suggestion considering the mileage.

see my sig for my build.

i would do a .25mm oversize, you dont know if your sleeves are straight, its only a little bit more, and why not do it for ease of mind..

after that all you need it a hone, no need to resleeve unless you plan on making REAL power with aftermarket forged pistons and rods.

and you need a valvejob, if you get new valves, im gonna suggest rocket valves or OE ITR valves, with a good 3 angle valvejob

and if you do an ls crank you will need ls rods with whichever pistons you want to use, this will give you a little more torque

and PLEASE dont do CTR's in a GSR, you could possibly have clearance issues and the compression will be WAY to high, go with some topline or OE JDM ITR pistons. you will have about 11.6:1 compression with those, perfect for any N/A cam

how much would it cost to hone the block? about how much power would i make with a setup like that?

 

if you go with an ls crank with ITR's and say BC3+'s with rocket valvetrain your looking at around 190whp, with a GOOD header ie AN-R, and a 60mm exhaust.

there are other small things to do also, like bored TB, fuel pressure regulator, and a GOOD tune on the dyno

How much would it cost to bore and resleeve

 

to resleeve it will run you around 1000 if u use oem pistons use ctr piston big bump in compression will put you around 12:1

I was thinking ctr but i wasnt sure what kinda cams i would be able to run and if i could run on pump gas

 

93 octane should be perfect

 

try to leak it down and also do a crank compression test with a 12v battery (unless its in a car already)

i recommend a rebuild with pr3 or p30 pistons in 81.25mm bore and bore and hone the block ... try to buy some used gsr or ITR rods with low mileage, get the head built or trade with cash for a ported one, etc.

what kinda pistons are pr3? and do ctr's have high enough compression that i wouldnt be able to run on 91 octane.
pr3 pistons or p30 pistons or p73 pistons?

sorry to keep this post up but i really need help also
would it be reasonable to resleeve the block with type r pistons

 

pr3/p30 is the b16 pistons. i have the pr3's which i ordered from honda. ask for 99civic si or del sol vtec.

p30 is the JDM b16 pistons.

with the CTR's, your motor will yield high compression, it will more likely detonate if not properly tuned on 91 octane.

i dont think its necessary to resleeve, unless the walls are cracked. for a high milege motor, often times it will only need boring. if boring is only needed, go with .25 OS pistons(81.25mm).
