any all motor with that kind of na power is not going to be very streetable, you need to look at other options or just lower your horsepower goalyeah its my daily, i want it to make 300whp in a 2600 pound car

I completely disagree... what may be streetable to him may not be streetable to you, but thats not to say he cant make 295-300 hp and daily drive it. I've had a combo that made 285 hp with many things not done.any all motor with that kind of na power is not going to be very streetable, you need to look at other options or just lower your horsepower goal
the car is 00 honda civic siIf you want to use the OEM k20aR block and make real 300whp, it is not going to happen.
If you have a large enough budget, making 300whp on a k20a block is more then possible but a lof of parts have to change including the 86mm stroke.
If you want to keep it a 2 liter and use the 86mm crank, then it is going to be really hard because it is going to have to be revved high and make usuable power after 9000rpm.
Streetable is subjective I agree.
It makes more sense to buy a k24a block, put some pistons and rods in it and slap a k20a head on top of it.
The cost for pistons and rods should be around $650...
Anothing thing to note is your weight at 2600 lbs... What car is this exactly?
Try to answer the following questions
Do you have a budget?
can you do engine work?
Do you have a local machine shop that you can trust?
What are u using the car for?
What kind of gas do you want to be able to run?
Is there a reason why you want to stay with a 2liter?
thanks man, k24a block is a jdm block out of what?Cool, roughly you have a few choices
1)get a rbc and some cams for your k20a with a good head and make around 230 whp, maybe more or less depending on the tuning, dyno, header and type of cams.. but that;s about it.. maybe 240whp dynojet tops
2)pull the block out, replace pistons and rods with 12.5 compression and continue with option 1. That will give you another 10whp... Stroke your 86mm crank to 88,5mm and use custom pistons to make up the difference in stroke.. that will give you another 10-20whp... so we are at around 240-260 area now depending on peripherals...
3)replace stock 86mm crank with a bigger crank like 90.7mm s2000 crank or a billet crank 92mm etc.. with custom pistons and rods... now you can make more power and still keep the original k20a block... but bore is going to be limited using the stock sleeves.. so maybe 260-270whp Assuming you are using cams, rbc etc and a nice header... To get that setup to 300whp would be possible with a really nice ported head and top notch parts... possible 89mm pistons and sleeves would be needed to reach actual 300whp SAE.
4)ditch the k20 block and get a k24a block with some 12.5 or 13.7 compression pistons and rods. Slap the k20a type r head on top with type r cams, and you are already at 250whp.... user some good cams and you can take this to 275whp with a good header and tuning.., 300whp is possible with a ported head and race gas...maybe more or less.,. I am generalizing pretty heavily here but I want to give you an idea how the extra 400cc of discplacement makes it easier to get closer to the magic 300whp where the car will go back to the future!![]()
for option three is there a kit out there or is that all custom. the 90 or 92 mm crank. with pistons and rods.Cool, roughly you have a few choices

I believe Brian Crower sells a 92mm billet stroker kit, with a crank rods and I think they offer the pistons as well... not to sure about the pistons thoughfor option three is there a kit out there or is that all custom. the 90 or 92 mm crank. with pistons and rods.
I think they come with CP forged pistons.I believe Brian Crower sells a 92mm billet stroker kit, with a crank rods and I think they offer the pistons as well... not to sure about the pistons though
if i get that kit but only bump the bore a little will i still see good gains.I believe Brian Crower sells a 92mm billet stroker kit, with a crank rods and I think they offer the pistons as well... not to sure about the pistons though
