if you have a k20a3, stock internals, a turbo kit around the size of a .50 trim, 750 injectors, fmic, in a 92 hatch.....what is the most boost you would be able to run?? what would you say is the max WHP it can produce with stock internals?? supposedly this thing is on 14psi with stock internals....i didnt think that was poosible b/c of the compression ratio in a k20 but im also not a pro at hondas....if he is on 14psi what do you think its putting down to the wheels??

 

I've heard of k20a2's holding a lot more boost than that on stock internals, but then again there are lots of variables such as turbo size, mileage of the motor, tuning, octane and driving style...but obviously that doesn't help you very much.

As for power numbers, throw it on a dyno. That's the only way to be sure. Butt dynos aren't very accurate lol.

If you are uncertain I would take it to someone that knows what they're doing. Have it tuned for longevity if you don't have the money to replace broken parts.

 

I would say 8psi on stock internals if you don't want to push it. That is what the average boost is for your average aftermarket turbo kit. A 50 trim seems much too big for a stock motor. I would think 14psi would blow up the motor for sure. I'm by no means a turbo expert or a K series expert but that is what I would say based on what I have seen in the past.

 

its most likely not a 50 trim....i run a .50 trim on my neon and his looks like its a little smaller than mine.....its not my car, its some high school kid trying to tell me that its putting 425 to the wheels - stock internals & 14psi... i dont raise the BS flag until i know a little about a situation

 

The majority of K series will hold a heck of a lot more than you'd think.

 

but a k20a3?? isnt that not the lowest powered stock k20??

 

That doesn't mean that it couldn't hold 14psi on a .50 trim. It may not last that long, but it wouldn't necessarily just....blow up. lol.

 

say it can handle it.....the k20a3 produces about 130-140 WHP correct?? the factory specs say 155-160 but by the time it gets to the wheels its gonna be less....now average a 10hp gain/ lb of boost(and thats probably over doing it)...he is running 14.....that puts him @ about 280....add some bolt ons and you have 300hp ABSOLUTE TOTAL with a super duper tune.....why is this guy trying to claim 425 to the wheels????

 

It's possible, but not likely (and not on 14lbs). I've seen several b-series make well over 300whp on 8-10lbs.


Here's an interesting video.

Why not just race him and see if his **** is really as fast as he says it is?

 

425WHP??

Tell him to dyno it or shut up. haha

 

so you wouldnt say so?? i know hondas dont make real high tq numbers so its not gonna shred the tires @ 80mph but it just seems to me that 425 would spin em pretty hard....it looks like in that 1st video like he has traction all the way through 2nd

 

bump....anyone else have some input on this?
