So i have this B18C1
im debating on either boosting it ex turbo or super charged
or keep it NA.
im currently waiting back on #'s from the compression test.
i know i have to change my
cams
intake manifold
pistons/rods/rings (debatable)
now if i wanna keep it NA;
what parts are sufficient to get a little more out of the motor?.. cams/intake?
& i know if i go boost
im gonna have to bore out the motor & change the pistons/rods/rings, injectors etc
i know one way is more expensive than the other
& i know with turbo as long as ur pockets are deep u can achieve whatever ude like.
even if i get a NA GSR with some mods pushing at least 210hp ill be content
what do you guys think?

I say go boost. Otherwise you will spend a lot of money at a machine shop trying to get everything ported and polished just to see minor gains. Hell if your motor is healthy, just throw a turbo kit on it, low psi on moderate sized turbo will do you good.

You don't need to do anything to the internals to boost it if your compression is good.
Getting over 200whp NA could end up costing you MORE then 250whp with a proper turbo setup.
You'd have to change internals for building it NA. It'll need at least skunk2 stage 2 cams or similar, and with that, you'll have to upgrade the valve springs/retainers, it'll have to rev higher to make use of those bigger cams, so you'll have to have the rotating assembly balanced, you'll also need at least 11.5:1 compression which means you'll need aftermarket pistons and or shave the head down...the list goes on...
There is a lot more work and cost involved in building a motor for NA power. You can build a turbo setup with a stock engine that will still be reliable, cost less and make more power.
I've done the research, it makes more sense to go turbo. You'll meet your power goals more easily and as long as the components are of good quality and are properly selected and installed, and the engine is tuned properly, it'll be every bit as reliable as a built NA motor, and be more streetable.
Go turbo.
My two cents.

really?
i just assumed that when ur going boost you have to upgrade ur internals
i wasnt aware that even if ur compression is good you dont have to do it. thxx
well with that being said
im assuming its not good to get an ebay kit or any nonsense like that,, its worth investing the money in a proper setup?

the b series motors have pretty good internals as it is. Just get yourself a good name brand turbo, a good header or a custom header,and a quality name brand bov and wastegate. The intercooler piping is okay to get off ebay, and usually the intercooler is okay too.

Why are you waiting for numbers back on compression test?? From who??? You do a leakdown and compression test and see the results right there and then. There should be no wait.

well the #'s are good
all over 200
right now i just want to do the essentials
timing belt/water pump/ tensioner/ alternator
im thinking of what else should be done to make sure the engine is up to snuff

^How many km's on the motor? Is it currently in the car? Does it burn oil?
Do a compression and leak-down test for starters.
If all is well, it should be good to go.
Replacing the timing belt, water pump and tensioner is always a good idea, especially if you don't know when it was last done.
Replacing the alternator is not necessary (unless it really does need replacing), it has no effect on the engine itself.

i dont know how many kms are on the motor cause it was already pulled from the car.
question guys
do you think its vital to add torque mounts?
i know alot of guys dont do it when u do a swap
and i realized that i should just change the tranny fluid as well while im there
amsoil ftw!
