hi members i am new in this but a 6 year mechanic. I have this challenge a civic 99 si with a 2000 gsr engine b18c1 everything is stock i am thinking this combination a ctr pistons, type r cams or skunk stage 2 cams pro, a skunk 2 intake manifold, tri y header, cometic gasket (.30 or .40?) and for tune p28 with crome any help is grateful

 

what head are you going to run? if you run a b16 head should be alright. GSR head will make the compression run pretty high making it a ticking bomb. just my opinion.

 

i am run a gsr head. you think this i not a good idea is beteer the ctr piston or itr?
the cometic gasket witch one is better .30 or .40?

 

high comp motor can be reliable.
S2 pro2 cams are better than type r cams. but if you go S2, just get pro3s. any S2 pro cam you need to do the whole valve train. So them your head will be built, make sure everything is up to snuff (u said your a mechanic so its not hard to do valve clearance/lash/etc) and it should be fine.
the bottom end will obviously be strong enough.
S2 pro ITM is also a good choice. Id get a bigger throttle body (not too big) and port match the ITM to that and the head. You can do it yourself with a dremel if you're confident enough.
headers: tri y, 4 into 1, doesn't matter much. just the size of them. S2 mega bomb headers (pretty sure thats what they're called) are recently released. S2 all the way. I have a full built drag motor 2.0 gsr and my head is built with all S2. never any problems. huge power gains.
tune: crome/uberdata is a good choice. cheaper and easy. if you're intersted in getting into hondas alot, you can buy a chip burner for $130 and download turboedit and tune yourself w/ a wideband. not too complicated.

what are you looking to get out of the build? just semi-decent daily driver power, or a faster street car?

(because honestly, $1000 ebay turbo kit, stock gsr, pro series ITM, dsm 450cc injectors on 9psi makes 300whp. aka my daily driver.)

 

a semi-decent daily driver power at least 180 to 190 hp at the wheel

 

I've researched on CTR pistons here before and it seems that most people recommend staying away from them. Dome design isn't the best for combustion, and it was stated that they're the heaviest b-series piston.

look into jdm SIR pistons instead.


welcome to HT btw

 

itp ot ctp piston?

 

ahh. ic. you don't need much mods then at all. i seen a bone stock type r put down 185 to the wheels.

 

i was told that ITR have less compression than CTR. I dont know why but...

IMO he don't need no stage 2 cams that would just make his car idle like **** and then he will have to upgrade not adjust upgrade his valve train if not he will blow the head is no time, stage one is fine, stage 2,3 and 4 is for built motors not daily driver, and if your going to spend $280 on a skunk2 manifold just put $30 more and get an edelbrock performer x manifold and a decent size throttle body should do the trick, on the pistons just get some hight compression cp pistons and you're all good to go. or if you don't wanna spend that much just get the ctr pistons which will give you more torque than the ctr pistons.

 

i said he'd have to do the whole valve train. read my post. ("any S2 pro cam you need to do the whole valve train. So them your head will be built") and i said since hes a mechanic that'd be no prob and wouldn't cost him labor fees cuz he can install and adjust all the stuff himself. ANY Skunk2 PRO! series cams need valve train upgrade. he said pro series. so thats all i'm talkin about. they only go up to 3. so pro 1+, pro 2+, pro 3+ all need a built valve train. he can get S2 tuner series, they're also in 1,2,3 stage. donno who does your tuning, but pro3+ cams can idle decent. not like ****. and the whole intake manifold is preference, thats your own opinion, i'm just sayin that you misread my post.

 

just did some searching around.
you could get away with just ITM and cams.
this is from Skunk2's site: http://www.skunk2.com/mm5/merchant.m...de=307-05-0270
thats 180 to the wheels w/ just ITM and stage 1 cams.
i'm sure you'll get headers and exhaust too so that should make the power your looking for.
plus you only gotta unbutton the valve cover and do timing belt.
not too much work.
no new head gasket, pistons, etc.
just a thought.
i'm not favoring any manifold or cam either. but i've seen good gains w/ S2 stuff.
thats all i found a dyno on.
just a helpful suggestion.
hope you get the power you're looking for.
when you plan on completing your build?
and the best of luck.
let us know how it turns out and what you decide on doing.

 

here another link: http://www.skunk2.com/mm5/merchant.m...de=305-05-0140
it has 3 diff graphs on it.
one on there had 186whp. gsr stock. pro series itm. tuner series stage 1 cam. headers.

 

that is whp or in the flywheel?

 

whp.

 

hi man i am tryin to find more dyno graph in the s2 web page but i can find anything

 

ctr piston with gsr head will give over 12:1 cr, id say b16a piston, should be in around 11.5:1, but im pretty sure these pistons wont fit properly on gsr rods due to wrist pin location, but i may be mistaken

 

can some one tell me if any d series header and clutch is the same for a d16a8 engine?

 

the engine is dohc
