Im going h2b on a dc2 I got almost everyrhing a full y built head skunk2 everything nd skunk2 pro3 camshaft...I also got a stock block h2b kit etc..im thinking about building the block but I need advice...my friends tell me to go allout with 14 to 15 compression but I feel like thats straight track..I plan on taking the car out once in a while for a ride in the street...my goal is 300+hp without spray..what I wanne know is
1.whats a decent compression to reach 300hp
2.what bore size I should go nd sleeves?
im sorrt if I write this all weird im doing it from my phone nd plz dont bash onme just need advise is my first build lol went from a crappy single to wanting to build this

 

Any one??

 

That's a mighty step to take for your first build.

I wouldn't go as high as 14-15 unless you plan on running ethanol on the street because you will definitely need it with that compression. Pro3's are really big cams though and will do good with a mid-high 12.xx:1 cr.

I'm not a h guy so bore/sleeves n bottom end stuff will have to be answered by someone else. Talk with Nah2b on here. He should know everything you need too.

 

Yeh big step first build I wanne go all out their really is no bidget..I was thinking maybe to just got with a 13.5 compression seems decent...nd I do plan on using e85 or racing gas if required

 

If you are going to run race gas / ethanol anyway then I would go with more compression.

 

Hey 1306, we are running a H2B crx, give us a PM with your # and time to call, we will try to help!

 

Are you going to run the car daily? If yes 300+whp is asking for trouble..
If it's a track only car.. go for a H23 crank, you need a block with 55mm main journals.
13.5 cr. A good flowing head. The pro3s & proper valve train. A good header and intake manifold should get to pretty close to 300whp.

 

Drcrx I sure will thank u...pippen y asking for trouble????lol nd yeah I was thinking of doing a h23 crank and I plan on making this car like a weekend car and maybe street race is once in a while just a car that I will take out when I feel like being fast I guess I already jave a daily...im going with a xcessive manifold nd right now I have rmf headers but thinking of getting rid of those nd going with bishimoto headers...

 

Step back away from the plate and do some research. If there is no budget have someone that knows what they are doing build it for you. An engine under that amount of stress has to be clearanced to the T.

I smell pipe dreams though. Everyone has a budget.

 

95x90mm
13.5:1 comp
pro3's
modified stock intake manifold
good header
b16 trans

300whp no problem and plenty reliable enough to drive on the street once and a while. alot of fun too. gotta run race gas or e85 though

 

I knew you would chime in eventually.

 

haven't been on here much, just on now for WCF. figured id see whats up in allmotor forum. looks like the usual lol

except now 400whp is the new 300

 

Same topics. Different people.

 

Yeah I already have a b16 lsd trans but its stock and I do plan on doing e85 just hope it all goes well nd I enjoy my self...also was reading something about h22s have oil problems?? Also nah2b..would u recommend a xcessive manifold? And what size injectors would I need to use?

 

No pipe dreams here brother I make enuff money to afford wateva I wanne do to my build...just wanne try nd do everythimg right no backyard build b.s

 

Also nah2b if u dont mind me askin what was ur build like? How long did it take u? Nd how much hp u end up with?

 

Good to see you check back in on us occ. Hope you are doing well. Keep preachin, were listening....

 

Forgot, NAH2B, give us a PM. would like to talk again soon.

 

You would be well advised to pay attention to what both NAH2B and 98VTEC have to say, they both have alot of experience in making power with H engines.

As NAH2B said, a properly ported stock manifold will work great, especially on the 95x90 build he also advised, so don't go dropping a bunch of cash on the excessive.

For the header, you will be leaps and bounds ahead of a Bisi if you already have an RMF!

I would just get used to the search function on here, and look at posts that NAH2B has made, and some of the other H testing in the all motor, hybrid, and even Prelude secions of the board.

 

Snobordboy..am taking every advice in is a long project alot of money is gonna b invested...

to gi e a heads up on whats going on I contacted dan benson nd will b sending my block on monday to get sleeved also contacted cp about custom pistons cuz im gonna b running a f22 cranck nd h22 rods...maybe carillo rods..im looking to maybe run a 13.5 compression...im having a issue with what manifold to use if any one has suggestions plz lmk

 

I'll let the other guys comment on the setup for making the power.
as for holding the power: if you are using an obd1 closed deck block, your best bet will be Darton Flanged Sleeves. they're $75 each to buy, and around $125-$150 each to install at any decent machine shop. If you're using an obd2 open deck block, you'll want Darton MID sleeves which are much more pricey

 

if your referring to the 97mm crank with a stock length h22 rod i think your gonna have a very short piston which will need to be custom, dont quote me on that tho. i would deff go carillo rods and cp pistons. as far as intakes to use if you dont have access to someone whom is knowledgeable to port. the euro r intake is a nice choice. but wont be optimal for your setup. best bet is for a owens engineering ported bottom plenum and spacer with ported upper. but good luck getting your hands on that i dont know if he still does them

 

Yeah I hear euro r is the best one to go with nd im still doing research on everything is very complicated because I dont know much

 

Best is a very loose term
