My motor has been pissing me off for a while with all its oil burning and shitty running goodness, so I figure I might as well crack it open and start rebuilding, have some fun, learn some stuff etc. If I wanna rebuild the motor for maximum reliability, what kind of things should I do? I want this puppy to run like clockwork, nice n smooth. However, If i'm gonna have it all apart anyway, I might as well do some upgrading since I have some extra cash to kill.

My question is this: What kind of upgrades should I do to the block/head to gain some power but also maintain or gain reliability? I've considered going turbo and may do so in the future, but I don't think it's something I'd wanna do right away. What's the difference between a motor built for turbo and a motor built for NA, other than different compression pistons?

 

I mean what it's all gonna come down to on how you do your build is on what you wanna do with the motor. If you plan on going turbo later I would say go ahead and build the motor for a turbo set-up i.e. low comp pistons and while your at it you could sleeve it and what not. I found this site ( http://www.importperformancepa....html ) and they offer like mostly everything you would need to rebuild a bottom end. If you want it to be nice and reliable though I would say stick with an N/A set-up. Me personally am a boost person but I don't think that my motor could be as reliable as a na motor with basic bolt ons and a little tuning.

 

but if I go with low comp pistons till I get a turbo, wouldn't I be losing power until the turbo is in?

and what are sleeves/what do they do? (noob question i'm sure >_&lt

 

Sleeves were explained to me as: you bore the motor so much over that you started to get into the water jackets, so a sleeve is a drop in cylinder wall that you put into the block so that you can bore out insane numbers. And yea if you put in low comp pistons for now you would be losing power. That's why you'd have to make a decision now if you were going to do it. You can go ahead and put in the low comps and suffer till you turbo or like go with high comps and pull an N/A motor and keep your power if not increase it. Don't get me wrong though plenty of honda people run higher compression motors and with a good tune it's all good. Not sure on how long they last or nothing.

 

if you want to rebuild and keep it reliable just use oem parts. for a simple na build do this:

have the head cleaned
3 angle valve job
itr/ctr cams and intake springs
p30 or p73 pistons
arp rod bolts
have the block cleaned
new oem bearings, gaskets, seals, etc.

This is exactly what you should do if you want reliability , OEM parts will be the best for what your looking for and you can definitly make a sizeable power increase while keeping it reliable .

Wow I think this is the first time I havent told someone to go turbo

 

i would do like they're saying above, but add ARP headstuds while you're at it. By the sound of it, you dont know if you should build it for boost, so your best bet is to not waste your money and just rebuild it stock. Even stock can handle quite a bit of power....let me tell you. Then if you dont decide to boost, you aren't stuck w/ an expensive rebuild that is effectively useless

 

That would give you like ultimate reliability. That can't be argued but you just gotta know what your going to do with your motor before you go buying up parts.
