This one is for those of you with B18C1 (integra gsr motor)...What's the most horsepower you have produced on stock internals, safely? I am aware that on stock internals, it's kind of a hit or miss type of deal, but if I can get an idea that'd be great...I'm just looking to get an idea of some numbers here so that I know if i'll really need to forge the motor. Thanks.

BTW: So far, the most i've heard (on stock internals) is 382WHP...but then again, they could be experiencing some problems in the near future...

Are you talking about stock bottem end and upgraded head/valvetrain or the entire block/head with factory parts?

Bone stock 382whp is REALLY pushing it. This is not recommended by any means. 320whp is about the safest limit.

i made 415 and it's lasted. not a problem took it out to put a built motor in.

WDG_729_ITR

The entire engine stock...block, head, transmission, etc...well, aftermarket clutch obviously because the stock one wouldn't last very long when you're pusing a decent bit of power.

WDG_729_ITR

So it if didn't have any problems then why did you take it out to put in a built motor? Were you looking to make more than 415 or were you just being on the safe side?

WDG_729_ITR

320whp is the safest limit?...Where do you get this number if I may ask.

92civicx

nope 338 thats it

ahobbs

i took it out because i had the money for a built bottom, and now that im working on this motor as we speak i wish i had left my stock motor in. just not a good morning for me.

WDG_729_ITR

Are you saying that you've pushed 338 or that 338 is the limit?

sgnlab

we made 450whp on a stock lsvtec. I know its not considered stock we also ran it to 9750rpms and ran a 11.2 pass @ the track in a 4 door integra. The motor is still runing in non boosted form till today!

i've learned from many experienced people that
it can handle well into the 300's if it has a good tune

rick_rabies

i debated with myself for a while about this. If its worth having it will take patience and work. I built my b18c2 with eagle rods and wiseco pistons. I don’t regret it. building at least with that so you can turn it up and turn it up some more

i make 343whp on stock bottom end but the head has Skunk2 Dual Valve Springs, Retainers, and cam gears.

Not to jack the thread but you cut some corners. what i mean is you didnt get it sleeved nor did you get the crank micro polished. I wouldnt recommend just pistons and rods since the sleeves give on whp applications.

rick_rabies

i never said i didnt hone the block and micropolishd the crank..i did. i dont have $2000 xtra to sleeve it. i will find me a b20 block and bore and sleeve that...yes sir

Death_to_Thieves

wtf? Not having a block sleeved is not cutting corners buddy. Stock sleeves can handle a nice amount of power with pistons and rods and a solid tune. There is a limit, but just because the block is not sleeved does not mean that he cut corners on his build. If he was looking for 550whp + I would probably recommend a sleeved block. Not to mention that there are members on here making 600+ on stock sleeves and race gas.

The stock motor can handle some power, just depends on the condition of the motor, who's tuning it, and how it'll be used IMO.

I've made 450whp/325tq on my old stock motor - 30,000+ miles on the setup and countless passes, and that thing is still running strong from what I hear.

We made 560whp/440tq on Gussy's stock motor in his street car - needless to say it did end up throwing a rod, but the purpose of it was to see if it can handle it.

In my opinion, you can reliably make 350-400whp on pump, anything over is getting and it's a coin toss.

99JDMHATCH

Your right but then again why spend all that money and not sleeve it IF you have the money. When i build my block next year i want to make sure that i have EVERYTHING covered before I finish the build. Meaning having the block built by laskey and sleeved by bension. Sorry for jumping the gun on the guy that mentioned his piston and rod setup.

Find out!

WDG_729_ITR

I plan on it...but i'd like to have an idea before I go pushing like over 350WHP and end up blowing the motor...

WDG_729_ITR

560 on stock! wow...yeah that's amazing that throwing a rod is all that you did lol...that's a lot for stock internals.

gringotegra

I have succesfully made over 370whp for about 20k miles now... i have been at the 420whp+ now for over 10k miles... Check sig for new numbers....

gsrauto98

I was wondering how much a block guard actually helps? How much more power will just a stock block with a block guard take?
