I was looking into an engine swap but don't kno hat would fit. I can get a 07 r6 motor but not sure if it will work. Also what other engine would fit?

I was looking for some power with the exception of buying a r6. Wanted to make a sleeper. Has anyone considered turbo for the fz6. I'm going to buy the two bros fuel programmer soon as well. What size of sprocket would be good to go with?
You can still squeeze close to 130 reliable horses out of the FZ for less than an R6 would cost if you know where to spend your money.
Hollywood - I respectfully disagree. A good used '08 R6 can be had for $5,500 to $7,500. The most I've seen out of an NA FZ6 is right at about 96 to 100 hp on a inertia dyno, an eddie current dyno about 17% less. Getting another 30 out would be a stretch at best.
Specifically what would you do? Just curious.
If you install the 636 I'd LOVE to see what it will do. I think that and the dyno tune will make the biggest difference.
That is something I want to do eventually but it will be way down the road when this motor starts to show it's age(40k-50k). I feel a good dyno tune is a must anytime you start to mess with internals. It does quite a bit for bolt on mods so start messing with the internals and it can really help. Wish I was still young again with no resposibilities and could throw whole paychecks at stuff like this....lol it would already be done. :thumbup:When I built my race quad I spent almost 10k in 6 months building it from ground up. Heck I'd just like to have half the money back I spent blindly on cars, trucks bikes and such I could build 2 or 3 awesome bikes. :rockon:
No probelm man everyone has their own $.02 you know. I was generally talking new for new though FZ6 at $7k R6 at 10k although I know atleast around here FZ6 can be had for less than 7 and good luck getting an R for less than 10,500. Either way though it's 3K to play with so we'll use that as a base line.
Filter, Airbox mod, Cat removal - $100 (2-3hp)
Slip on pipes- $300 (3-5hp)
Port&Polish, new valves, cams- $900-1200 going all out (10hp) this is kinda hard to judge as I have yet to see the inside of the head and really don't know how much room there is for improvement and am leaning more toward there being a lot of room to increase flow velocity of the head. Just going off general hp improvements I've seen from other bikes having the heads reworked.
Power Commander and Dyno tune- $450(5hp)
636 Big Bore kit w/ 13:1 pistons- $500 parts and about $250 for machine work. (5-10hp)
All the prices are taken into what I know I can do things for and saving everywhere possible buying pipes, PC used which saves bunches and doing everything I know I can do myself saving labor which is pretty much everything but machine work and dyno tune.
Total cost $2800
Total power gain 25-33hp based off corrected factory baseline of 98 puts you right at 130 give or take a few either way. Most of this is theoretical I very well know as there are no real baselines to go off of on the FZ6 but I feel my hp guestimates are pretty conservitive for the most part.
When I used to race and build MX quads this is basically the jobs most of them got and we usually went from stock around low-mid 30's hp to mid to upper 50's and they ran like champs seemingly forever. It's not any single thing but the sum of all parts that makes a good motor. :thumbup:
Like I said before everyone is welcome to their $.02. By that train of thought Mod_street drag bikes would be making basically stock HP not nocking over 200HP. Go to your local drag strip and see what large portion of drag bikes are there, usually it's old Kawasaki litre bikes that came stock with 130hp at best and most of the ones I have seen are now upper 180's to over 200 NA granted most of them are now 1300-1500cc but it all works the same. You can get near 10 with just the bolt ons and a good Dynotune. You don't just add up all the Max but you can judge what each one will add working together once you've actually done it a few times. Your right though they do all work in conjunction with each other and in my real life experience building engines like these the sum of all is better than any single mod. It's not about riding on the peak of horsepower it will increase your power all through the RPM range and the torque you will gain can be amazing which mostly would come from the 636 the others wouldn't do a lot for it. Honestly there is very little good info on the net about real life engine building...there's a lot of people out there doing right ups and giving info based off theoretical ideas and in the real world it doesn't mean squat. :thumbup:not to rain on your parade.. but doing all those mods would not give you 25-33 hp... there is a huge misconception about adding mods and what they will produce.. there was a great writeup about this somewhere, but i forget where i had seen it .. anyways..
honestly with these mods, i would guess that the power you would get would be more along the lines of 10-15 hp peak... you cant just add up all the max's and arive at the number, it doesnt work liek that, due to all those mods work in conjunction together. either way though, your likly to dump a whole lot of money into a motor that would have been better spent on a new bike.. and besides, no one here really rides right on the peak of hp.. so really, the money would be better spent on a bike that makes more low end tourqe.. my 2 cents
Like I said before everyone is welcome to their $.02. No offense but 10-15 with head work and bigbore though man you have lost it have you ever actually done any engine work or just read about it, by that train of thought Pro_street drag bikes would be making basically stock HP not nocking over 200HP. You can get near 10 with just the bolt ons and a good Dynotune. You don't just add up all the Max but you can judge what each one will add working together once you've actually done it a few times.

use puncutation... yes, i have built up a few engines in my day and do know a bit about applying theory to practical aplications.. its nice to meet someone else who actually knows what they are talking about as well... sucks dealing with "kids" who know theory or wrong theory and no practical realworld applications...
as for not using just hte peak HP numbers.. i agree.. it would be better to work on the whole rpm range them just the top.. i would say that if someone wanted to really beef up and build a great motor, your going to do lots of dyno tunes.. i would do the head port and polish first.. (along with all the bolt on mods obviously).. then dyno tune and try to get a good even setup across the rpm.. before i would spend the money on a big bore kit, i would do this first and see what you get.. a good setup like that could net you 20hp without having to do the bigboar kit.. depends on how much power/ how reliable your looking to go to.. :thumbup:
