hey guys, quick Q. what parts would i need to put into a b17 (92 gsr) to rev to 9k? and could i retune/chip the stock pcm to up the limiter, or would it be better to get a different pcm? thanks guys.

 

Upgrade the valve train (springs) and probably ARP rod bolts. You really need a programmable ECU to tune it correctly. Lastly, you will need to get cams that will make power that high or there is really no point to this.

Please tell me you have a good reason to wind it out to 9K and this isn't another "cuz its kewl" thread.

 

no, it is. lol i guess i'll just leave it alone since its good to 8k stock anyway....

thanks for your help.

 

If you have already done the basic I/H/E stuff, then upgrade the springs, throw in a bigger cam (BC3+ or larger) and tune it. You will like the results.

 

i haven't done anything to it, the stock b17 is good to 8k. thats when the stock tach redlines, and what it says in the brochure (g2ic.com)

 

if you're stock then stay in the stock rev limit.

 

^^^^ This is right.

 

I love kids that just think its cool to rev the **** out of there car. when it doesnt even make power to that.. ey yi yi. people gotta learn.

 

maybe i just like the sound? and i know it doesn't make power up there. if i did this, i would put a different cam in it to make it worth while. and i'm not sure i'll even need it, since it's going in an car almost identical to the one in boostedEF's avatar. mines a black 89 though. so what does cam's, rod bolts, valve springs and a tune run? (money wise)

 

anywhere between $200 to 600+ for a complete tune. including dyno time. or can just be street tuned. you have to buy some sort of engine management. can be pricey depending on what kind you go with. cams, rod bolts, springs, retainers and valves will be over $500 if bought new.

 

edit: i googled it, so would something like the s300 from hondata work? then i would be able to mess with the tune myself with my laptop, correct?

 

if you have no idea how to tune i advise you not too....you'll blow the motor faster than building it. for a b17 to rev to at least 9k..you will need to bore and oversize your pistons to larger ones with higher compression. uprgaded valvetrain upgraded cams to at least pro2's or higher. so basically rebuilding the whole thing from bottom up with new pistons, rods, yada yada...and a good tune by someone who knows what the heck they are doing....i would say cost range from at least 2-5K for everything including parts and labor

 

i don't know how to tune, but my dad knows what the engine needs while its running in order to perform better, so he could tell me what to do and i could do it. i like the idea of being able to change the engines parameters with a click of a mouse. but i may leave it in the stock rpm range and throw a cam in with the s300 anyway. i don't know what i'm going to do, i just wanted some info on it before i made up my mind.

 

LOL EVEN If your dad knows what an engine needs to run properly does not mean that he understands what all is goin on in tuning. Has he tuned a car like yours before? If youre gonna go out on a wimb you may as well just buy you an ecu thats chipped no rev limit and run it til it pops. IMO Go with experience, find a shop or someone you know has done this before and have them do it. If you want to run 9k all the time I agree with these guys rod bolts, valve train, cams, header, and a short runner I/M that will make power in that range. Being cheap is more expensive in the long run. I know how to tune myself BUT I only do it on my car I wouldnt feel safe with someone elses. Im no pro, so i just make a basemap for mine to get it to a tuner. Your stock rev limit is 8200 right? you will barely tell the difference in sound at 9.

 

i still think it may be beneficial to get an s300. but i don't want any criticism, i just wanted to know what was needed if i wanted to rev to 9k. someone i was talking to said that alot of guys on here rev to 9k all the time, i just wanted to know how. and as far as tuning, i could probly figure it out if i researched the hell out of it (but i do that with a lot of stuff).

And no, other than messing with the cam timing (adjustable gear) and putting new rings in his civic, my dad hasn't messed with these before. although he did rebuild a 91 teg, it blew a head gasket and warped the head and all of that good stuff. anyway. i'm sure i could find a local tuner to give me some pointers if i had an s300. and the sound thing was just a point, i don't really care.

 

dude... your motor stops making power at 7600 rpm in stock form. it doesn't even make sense for you to rev up to 8k. have you ever seen a dyno chart on your engine? paying $500 for a hondata s300 isn't going to accomplish diddly squat. these people are trying to give you some sound advice. go ahead and blow $500 on an engine management system if you want because the next thing you'll be blowing is your engine. unless you spend money on cams, valve springs, retainers, new valves and a head gasket set (at the very least!) you might as well leave your car the way it is! don't think you can just "drop in" a set of buddy club cams without blowing your engine!

you'll easily have to spend upwards of $2000 when all is said and done to rev up to 9k just with a built head and a stock block ($500 for the s300 and another $600+ on a tune without buying any valvetrain parts)

 

good god these things are expensive. i think i'll take everyones advice. i'll leave it stock, swap it in, and spend any money left over on my rx7. at least it's capable of real power XD (chevy 350)

 

N/A sure is expensive, revving high doesnt automatically mean you'll be fast. it depends on where your car makes the most power, which depends on your setup will it be for midrange power or high end power.

 

yeah. the stock b17 should be quite a bit faster then a stock d16, right?
