Internals It seems that crower is going to make internals. I am recently new to the 7th Gen Civic moding, but I was wondering what everyone's take was on KMS products from www.honda-performance.com.
Also, what does upgrading your internals do for your engine? Does it give your engine more horsepower? higher rev? Any help on these questions would be much help.

upgrading your internals can be good or bad.
what u need to do on your part is ask yourself more questions first.
for example: what do i want from my car? what type of racing (if any)?
and if u know this stuff letting us know will be more help in answering these types of questions.
like if u want boost. u might want to think about lowering compression ratio, cast iron blocks, sleeved head i think it was cast iron pistons crank shafts and cam shafts.
if u want all motor then u might want to get more dissplacement, higher compression ratio, work on your cams to get higher lift for intake and exhaust. or just get a swap for a k20 or similar and have a DOHC.
ALSO BIG THING HERE IS USE THE SEARCH BUTTON! its located near the USERCP button. thanks for joining us and make sure to come to the norcal MEET on jan. 8th.

crower has rods for our motors and i know they are building another members motor and in the future will be making products for our motor.
I don't believe that kms has anything except a HG and a IM.
As far as internals go (pistons, rods, crank, bearings, etc...) they basically reinforce your motor to handle the extra heat and pressure that a turbo produces. They will not give you extra hp, unless they are lightened up. Since u posted this in the F/I forum, i guess u wanna boost. If you do swap out the pistons, u will need to go with a lower compression piston to run boost safely.
As far as higher reving, the motor can only rev as high as the ecu allows. During high reving, the head is what takes the abuse. To reinforce the head, you would need to install stronger valves, springs and retainers.
Also, other good things to get for the motor........... headgasket and apr studs.

Rep Power: 285 Upgrading the internals allows the engine to deal with higher thermal load better when applications such as forced induction are applied. Forged pistons resist heat better than stock. We have a container FULL of melted pistons in my shop. Forged rods follow the same concept. Stock rods, all though some strong enough ,for ex: K-series, b-series, sr20's, etc, can hold well under moderate boost after being pinned, but for the most part stock rods will break then plant themselves right in your block.......ouch. Forged rods, resist heat (once again) better than OEM.

Rep Power: 0 I really don't know too much about internals and such, but what is the difference between building the engine for n/a or turbo - in terms of compression, parts, etc. I've read around, and found that on a turbo you want lower compression... why? and why higher compression on a n/a?

I wouldnt recommend getting a "bullet-proof" headgasket or any thing that can take a ridiculous amount of stress. I like to think of the headgasket as a fuse, a warning sign to something catastrophically wrong. If it blows, you know something definitely isnt right. If you get an indestructible one, it wouldnt blow if something was up....and your whole motor could die on the inside without any warning.

Rep Power: 0 ^^Yeah on a stock motor, but if your building everything else....
Nobody here is boosting with sleeves yet so who knows how much boost the nippon leakless can take.

I saw supermex's pictures of his block, I dont believe those are the full Iron Ductile sleeves that he has installed. Those are just Inserts from what it looks like and are not the type that would handle high boost.
We'd really like to see more people get into building the d17. we have several d17a2 block cores already waiting for you guys to get built up.

Yeah, I remembered that right after I left the office. Last I heard he was running low boost to break everything in.
