Was wondering what horse power limit (ballpark) with a good tune this motor can handle safely.

B18b1 stock sleeve block
eagle rods
cp 9-1 compression forged pistons
acl bearings
freshed up block
arp rods studs
arp head studs
stock crank
crower stage 2 turbo cams with springs and retainer kit
stock valves. (reconditioned)
no port work


Just wondering from yalls previous experiance

 

I have this stuff extra and I want to build a fun weekend car in my new hatch


And this will be on Crome 93 pump

 

There's no clear cut answer for this question. Could make 200whp and spin a bearing due to wrong clearances. Could make 500whp and last for a long time. If your just looking to have fun, i wouldnt go over 300whp, just to be safe.

 

Oh I am running 750cc rc engineering injectors with omni 3-bar map sensor

 

This is correct. Some make 500 with stock sleeves but I sure as hell wouldnt do it. Lots of people will tell you go to 400 or so since you have forged internals

 

Ok cause when I was planing this I was shooting for 350-401 to the wheels

 

Personally i have been running right at 320hp on a completely stock B18b1 for a few years now. This is on 16psi using a garrett t3/t4 to4e 60 trim turbo. I am definitely not easy on the car either.. It catches hell.

 

what head are you using. vtec or ls

 

With a good tune you'll be fine. Personally I'd go to about 375 for longevity, above that you'll just break more **** and spin the tires

 

i mean all i have is a B18c with rods and pistons making 460. and its perfectly safe. 500 is my limit on pump. its all about getting a good tune. i wouldnt worry to much about your hp limit. you will probably never get to max it out. you'll be fine

 

Its a bone stock b18b1.. so it just an LS head

 

its hard to say what the limit is, the limit would really be what the tuner is capable of. But i would stay around 300-350WHP, that way the motor should last a long tiem and you have less chance of breaking things outside of the motor (CV Joint, Tranny, Mounts, etc).

 

^ x2 on that. friend of mine had a bone stock ls. just rods and pistons made 345 on 20psi. ran really good. just had a ebay turbo as well.

 

Thats almost my exact setup except I have BC turbo cams and 8.8 slugs. Am gonna test engine hp limits here soon with new turbo. Will post results.

 

nice, thats about what Im pacing to make, 314/280 at 17lbs.. gotta love the tq though

 

Your goals are reasonable for your setup. I'm in about the same situation: stock sleeve and built bottom end, and i'm currently shy of 400whp. It is a fun amount for now, but i plan to push it a little further this summer. The limitation you face is your fuel...not that you wont have enough, but that it won't handle a great deal of stress. I would still say 400whp is within range. Good luck with your setup

 

Thanks guys. I mean I know someone that is running 11.60's all day long on a similar setup In a integ with slicks. But he is only putting down 270 hp during the last dyno days around here. As of now there are no 500hp civics around town that are driven more than once a month. It is just a goal I had to make a damn fast usable power street strip hatch.
