I have a 88 crx hf with a B20VTEC in it. I want everyones input on this. I'm going to build my motor to make over 200whp. I know this can be done and still be a reliable daily driver. Its going to be after the first of the year before I can start on this. Due to surgery I'll be in a cast till the end of January prolly. But back to the point. If your just going to get on here and be negative about this then don't post. I'm not sure what parts I'm going to be using but I want the motor to rev to 8500 safe or atleast 8200. I know the head will but the bottom end is what I'm worried about. I plan on blancing the bottom end and use all arp bolts. The compression will be somewhere around 11.1.1 or 11.5.1 but I still wanna use pump gas. Not sure what pistons or rods to use. For the head I was thanking a RM's M22 cams and full valvetrain. Prolly a good port and poilsh. If anyone can recommend parts, or people to help me with the build. Kteller is like 2 hours from here so I thank I'm going to try to get him to do a custon exhaust for me. So lets see how much power it really makes. I plan on using hondata. Any input would be greatly appreciate.

Thanks alot,
Chris

 

i have a 2.0L with comp above 12 on cali 91 octane, eagle rods arias pistons...
however minei ssleeved but take it to 8500 easy! not saying that i do on a regular but more liek 8200...

with a good set up matcched up right over 200 will be done, the torque is a big + too!

 

Well man that do u recommend I do with the bottom end. Reving to 8k will be fine but I won't do it all the time. So let me know man thanks.

 

Ever thought about using a GSR crank and rods? Here is dome good reading material.

Work with Kteller and we'll try our best to help you.

We have a 81.00 USDM B18C5 with crazy headwork / M22 cams / SMSP Header / AEBS IM / J's Intake making around 210 dyno jet whp. The motor runs good and when driving it keeps on pulling, you just shift for shifiting sake.

Thanks for you interest.

Whats the 81.00 mean. Does it have any bottom end work. Thanks Rocket and Kteller for all the help. Even if it doesn't make 200 whp I want a quick car that I can drive daily. It won't be driven everyday b/c I have a 90 talon tsi I like beating the **** out of.

 

81.00mm = stock bore. 1794cc Stock USDM Bottom.

Just hightlights that power can be more economically made with the cylinder/cams/header/intake manifold.

 

to Rocket Motorsports an Kteller

 

So Rocket, your saying I can make good power with only pistons in the block, and head work. I decided that if I make 200whp I want it to be around 6500-7500 rmps so I don't have to rev the block too high. I'm going to be using a Kteller exhaust for sure. I may even see if he would install it his self.

 

if you dont intend on reving past 8000 look at the dyno in my sig.
if you are looking for solid power with the least amount of mods stay in touch w/ ROCKET. im not his friend nor have i met him but his posts speak volumes of his knowledge and he can help you pick the right and best matched parts the first time or you can do it my way and change your set up weekly in the search for more power.

Hey man what would u say a good set-up would be to make 200whp daily relaible. Just let me know. I pmed u (na200whp). Let me know what u thank.

 

With proper headwork and cam timing a 2L BVTEC motor should hit 200 whp at 7 to 7.5K.

 

What would proper headwork be???

Mild P&P with a good valve job. If there is one thing I have learned it is that when a good engine builder is willing to share his knowledge the importance of a good valve job always seems to be a topic of discussion.

agreed

 

Hell yea thanks man. Can anyone recommend someone to do my headwork. I was thanking about letting Rocket build my motor.

 

Whats the difference in prepping the head for a b20vtec then a lsvtec. I will lsvtec rev high and would it be safer to build. If so can I take the head off the b20 block and put in right on a ls block .

 

not sure about every one else but the only thing i do different with 84mm bore blocks is round the edges of the cyl heads combustion chamber where it meets the mating surface to reduce hot spots. yes you can take it off the b20 and puy it on an ls block w/ no additional work.

 

not to hijack ur post but how hard do you guys think it would be to make 200whp N/A on a B18B1 block? I was considering sleeving the motor and boring it to 84.5 with endyn pistons but im not sure wut else would be needed to make 200whp reliably.

 

84.5mm bore b18a/b is not necessary for 200whp. Stock 81mm bore or even .25 o/s will do you just fine. compression somewhere in the 11:1 area, a big tb, decent flowing intake manifold, nice set of cams (buddy club spec 3's) and decent header/exhaust combo will get you there.

 

Would you recommend a vtec conversion or would it be possible with a stock B18B1 head?

 

im sorry, i thought you were insinuating going VTEC already. If you wanna stay with the b18b head, 200whp is possible, but much more difficult i believe. The non-vtec heads simply dont flow as well.

 

well im interested in ls/vtec aswell as simply turboing the motor but thats a whole different thread.

Basically if i put on a B16 head, B16IM or GSR IM?, crower cams, endyn pistons.......etc etc u think i could make 200whp while running around 10-11:1 compression?

I wanna be able to possibly turbo the motor down the road so i dont wanna run super high compression.

I personally like low-mid range torque more than high rpm HP so keep that in mind.

id recomend finding a b20 block then. you will have all the TQ you need w/ less mods

 

i know i would like to get a B20 but i already have a 99 B18B1 with 00 GSR tranny so i needa work with this as my starting point.
