I neeed help with my ek gsr build? I have A.....

B18c1 block
micro polished stock crank
stock rods
CTR piston kit
B18c5 head (when i ordered the piston kit it said with my block and head i should have12:10.1 cr is this true)
brian crower stage three cams
mild port on head
intake manifold not chosen(should i run ITB's?)
header not chosen(hytec replica or the new skunk2?)

Im looking for 200 to 250 ill i make this power? What would i have to do to buy or make a vacum box for itbs?

 

the margin of 200-250whp is a little steep. i would expect a margin of between 200-220. 250 whp is nearly impossible with a 1.8 liter displacement. it sounds like a decent build, but i am always slightly frowning on using ctr pistons in a gsr, regardless. omniman posted a compression chart of using ctr pistons in almost every honda engine made. from that, the average compression ratios were a little above the norm as far as daily driving. thats just my opinion though. those things are known for boosting compression way high. with a b16 crank, they still make right around 12:1.

 

Did you check http://zealautowerks.com/bseries.html ?
Rough check gave me 12.7:1, extremly to high for street gas. Can this be tuned, yes but why make it this hard. Get JDM P73's or P30's, mill a bit on the head and/or block and you're in the mid 11.5:1 range.

As for the horsepower range. Lets look at it this way.
200whp lets say about $2000-2500
225whp $3500-5000
250whp $5000+
To get those higher horsepower numbers your headwork could cost you more than $2000 alone. You'll also need a custom header SMSP or Hytech. To get to 250whp, 2.0 liter.

A little more homework and set a budet.
Is this a daily driver, track car, drag racing?

Take a look at the motors in this thread.

Ok guys thanks ill prolly just sell this crap i got and put a k in my car? Have you ever heard of anyone making 400hp or higher with a k? ha lol

 

Yes.

Unless you have money to burn and a competant person to do the build for you, you need to stop dreaming and be a little more realistic with what you want.

 

You can lower the static compression ratio by using a thicker head gasket.
Cometic makes .030(stock) .054 .060 which will get you closer to 11.5-12:1 and be able to run on pump gas with timing retarded. Usually 190-215hp on a dyno with that set-up.

 

so you want 200 hp-250 hp, and 400hp with an entirely different motor? get a grip.
