how do my housings look?

but we drive FC's, not FD's so we cant spend all this money

I will then take the difference and put into various mods both on the engine and the car (exhaust, etc) on my car. Then we dyno. We will have spent equivalent amounts of money but I guarantee I'll come out ahead.
but you wont be allowed a handicap because your using junk parts... both cars will have the same mods...
You can sit there and whine all day long but if you stand back and look at the big picture, my guy is going to make 220rwhp and yours will make 165rwhp at best. But, he'll be able to brag to his buddies that he's making 125psi compression, and I'm only making 110. Yay.

His same $2500 spent with me will get him a used housing rebuild with a large streetport, FD cornerseal springs, a full exhaust, intake and TID mod and maybe even a set of injectors and safc.

ill say it again..........
same mods....
car with chrome missing= less compression=less power
car with no chrome missing=more compression=more power, used or new housings as long as there is no chrome missing, and no shrinkage from overheating...

the money that kevins customer saved could buy more mods.
both points are valid.
anybody willing to spend 2500 dollars on a stock rebuild probably has enough money to afford some mods anyways so it doesnt really matter.

Dang, they grow 'em dumb out there where you're at dont they?
Okay, have it your way.
Same mods...
car with chrome missing on used housings = $1500 but slightly less power (5% or less difference in power)
car with new housings and good chrome = $2500 but slightly more power
IT's the same thing, however you want to say it.
You're the one not addressing my points. You cannot dispute the fact that power mods are a better bang for the buck than the cost of new housings versus used housings. I want to hear you say it.
And we all know that a new housing engine is just as easy to blow in a modded setup as a used housing engine. Who wants to drop $1200 on new housings and blow the bitch up with a boost spike in 6 months time, when they could finance their next engine by not buying those new housings and instead using the good used ones?

No one could be so stupid as to not realise this.
I have personally never seen a used housing without _some_ chrome missing/about to be missing.
I can see Kevins point very clearly and he makes a good one.
I'd like to see you, or anyone else for that matter, take kevin up on _his_ challenge, not YOUR challenge 680RWHP12A, no one would be that silly.

excellent you finally acknowledged my point....thank you
and in answer to your question if you put exhaust and msc. other mods rather than buying new housings you would make more power.....BUT for how long? once the chrome starts flaking it usally gets worse fast!!

Dude, obviously new housings will make slightly more power than used housings.

obviously the new housings run under the same conditions will produce a longer life. But it comes down to the customers needs, and his wallet. I personally could not afford to buy brand new housings, i already had to drop almost $500 on used irons, then about another $600 on the rebuild. I'm happy with my setup and kevin and many others have already proven that it works just fine. I see no reason to replace the rotor housings if they are in good shape still, even with a bit of chrome flaking on a daily driven street vehicle. It would be a totally different story if i was building a high horsepower engine.
Just want to say both rob and kevin are right, bottom line is that you get what you pay for.

The smart thing would be to just save for a few more weeks, or months and buy the housings. But when your car has been sitting for so long, and you see rotaries fly by you in your minivan "Damn!!! that sucks"
I just can't wait anymore. I'm hoping since the motor had compression on both rotors, the housings can be reusable.
Thanks Rob,

i guess i should chim in on the subject since i just got a rebuild recently...yes rob is right that new housings should be used when flaking occurs.....but if u put urself in my shoes.... my rebuild cost almost 1800 to date...the rebuild itself was 1200 with the help of kahren then various gaskets and crap...it all adds up...yeah...if i have a money printing machine it whouldnt be a problem, i'd get new housings/rotors/irons/seals probably even send it to japan to have it proted by RE-A..... the whole nine yards.....but sadly there arent any of those machines on ebay......i went into this project knowing that i will be reusing old parts. i understand that my motor will not be 100% mazda spec.. kevin's business is well known and has much success....people that bring their motors to kevin know before hand that he will be using whatever parts possible from the core....and the end result is kevin providing a running engine.....thats enough for most people...im not saying its the RIGHT way to go...but for most people....cost justifies the end result...... im sure u know that majority of the FC owners are in their late teen's to late twenties...and honestly....we dont have that kind of budget for a rebuild....sure..i can get a second job..save up and get a perfect rebuild later on...what means i'll be carless with no means of transportation getting to my newly aquired second job.....
jacob, kevin says ur housings are ok to use.....if u trust his/your judgement then go head and use it...but u know u cant expect it to last as long as a brand new motor that rob builds......

USE EM!!! dont listen to that 680RWHP12A guy. He's never been poor before. He probably has a hawaiian punch water fountain. The used housing will give you a good amount of life and compression. As RotaryResurrection said... it's the best bang for the buck.
