i am in the process of rebuilding my b18c1 gsr motor.
the vehicle is my daily and i rebuilding due to blown piston ring on cylinder 1

Due to being on a budget the plan was to rebuild to stock. But at the same time i dont want to cut any corners and anything that i can to make it stronger im willing to do.

i am going back together with all arp bolts and studs. and replacing oil/water pump, timing belt & tensioner, and all gaskets with oem parts. using acl bearings.

i willing to upgrade but theres always a "hidden" for example RS machine itr pistons are only $150 but converting my 01 gsr to obd1 and tuning will run me at least $500.

What are some worthwile upgrades i should make while i have it apart that i shouldnt miss out on?

things i was thinking was hondata IM gasket( would my stock studs work)

how about a exedy stage 2 clutch and a 8lbs flywheel ( i have a good deal on it)

anything you guys think is worthwile doing while i have it apart would be apreciated.

 

would i be better of building it back to stock and use the extra cash for bolt ons?

 

even with bolt ons, without a tune, you won't get the full potential from the bolt ons. I would at least get some usdm itr pistons, if not the jdm. Then when you can safe up for some cams and a tune, you'll have the higher compression to get the most out of your cams. Also depending on your budget, look into getting a ls crank and rods, only cost me an extra $300 for ls crank, rods, and usdm itr pistons in my gsr build.

could i safely run my engine with itr (jdm or usdm) pistons with a tune for as long as i need? or do i risk detonation!?!?

 

without a tune you mean? I wouldn't reccomend it, but if you can at least get an obd2 type r ecu and a blox intake manifold, that shouldn't run you more than $260-280.

 

i would like to go the obd2 type r ecu.

what can i do to my b18c1 to match the map to the p73 ecu

itr pistons, IM, an cams?

if i can just pick up the ecu and it take care of most of my tuning problems that would be great!

 

yeah, pistons, im and cams, are pretty much the main difference between gsr and itr, besides hand ported head on the itr.

why dont you just get an obd1 ecu and run jdm itr maps.

 

ok im going to try to just stick to my plan of just building a stronger stock set up.

i took the motor apart this past weekend to find out the problem i was having was due to a bent rod. im planning on picking up another oem rod to replace it.

would shot peening the stock rods be worth it ?

am planning on getting my entire rotating assembly balanced sense its all stock parts is it worh the trouble?

dont know much about shot peening but u should always balance the engine assembly. the last thing u want on this rebuild is premature bearing failure because u didnt balance anything. u might wanna pick up some arp rod bolts, there cheap and stronger than oem. check all ur other rods too, u might be better off just replacing all 4 of the rods than just one.

 

i got 3 used stock gsr rods. I say 3 because on rod has a piston that smacked a valve. The other three are cherry. 70K miles on them. I went ls crank and rods in my gsr block so i no longer need the gsr rods. Make me an offer on one, or all three.

i already got arp bolts and studs for everything

only one of my rods were bent. everyone think i'l lbe fine if i pick up another used one to replace it. then get them all shot peened and arp bolts on them?

thanks

Apparently you don't understand what "balancing" the bottom end really involves? Assembling something that isn't additionally balanced beyond what OEM parts are isn't going to cause premature bearing failure.

 

F shot peening!!

MY rods are bone stock in my lsv and I rev that thing to 9200 daily.

Also may I suggest using oem bearings. Matching the colour codes will give you the ultimate precision.

yes but the motor runs alot smoother with a balanced assembly. and hes using used parts whos to say that the balance from the factory is even close to one another???? if hes gonna be mismatching rods i would get them balanced regardless.

 

and he only has 3 so yea maybe those 3 rods are balanced before but hes getting another one and hes using different pistons. whos to say that all 4 pistons are going to be the exact same weight from factory or even close? u know there not going to be. which is way i said get everything balanced.

im keeping my stock gsr pistons, but i do need to pick up another rod. then getting them all shot peened so i dont bend another again so easily.

to be safe im going to get everthing balanced better safe than F***ed i say!

 

nice advices guys its going to help me on my all motor build too!

 

Advice with what?
