I dont want anything fancy, how much do you guys think it owuld cost in so cal to rebuild both stock turbos?

 

BNRsupercars.com they will rebuild your stockers for 750.

 

are there places that will do it cheaper?

 

no, $750 is cheap and he does BNR does excellent work - could try getting a used pair off partstrader (gamble) - most people who do rebuilds for 3rd gen turbos fail. BNR has some experience with turbos and does them right.

 

YEa...$500 bones at turbo city..

WWW.TURBOCITY.COM

 

Yeah, and I guarantee that in less than 6 months, those turbos will be blowing smoke again. Do a search on rebuilt turbos ... this topic has come up a number of times ... a good portion of them probably started by me.

In fact, lemme give you the short answer: you can waste $500-$1000 every 6 months to a year on rebuilding the same crapped-out turbos ... or you can just cough up the $3000 or so and get some brand spankin' new turbos without any hassles (other than your own abuse/neglect) for the next 4-5 years. You might save a little now doing rebuilds, but you'll end up paying for new ones in the end.

 

yeah...and what these guys dont know is that turbo city was sued a year ago over multiples of their turbos failing on the the rx7 owners. had the guys who expressed a recommendation toward that shop owned rx7s a bit longer they would have known the history of turbo city rebuilds on this site. They would also be aware of the lawsuit that company lost regarding the quantity of failing turbos on 3rd gen rx7s that they built..which is what led to that lawsuit.

i had a set from turbo city and they failed in one day. literally leaked all over the floor of the shop. they did not cover them under warrantee.

they looked great to the eye though when i got them.... i drove them leaky for about 3 months before they smoked too much to drive it. i was forced to get another set or catch fire..or worse blow my motor from oil loss.

performance techniques also sucks (they own www.turbonetics.com and are NOT turbonetics)...theirs lasted less than three months and sounded like a dentist drill. when i drove the car to them they said they would warrantee them. however...they did not...which cost me another 1100 bucks. wasted money. ask black r1 or toadman...they heard em buzzing and whining when I drove past them.

do NOT go with the cheap places. you will be building another set shortly if you do. Dont believe me...call rotarty reliability and racing and ask them. they have dealt with hundreds of turbo cases.... they were one of the shops that have sued them AND WON.

7148398018 is the number to rotary reliability...their new builder has not had one set fail and they come back looking cherry. ask for nick or louis. they are pricey though...but you get what you pay for. I think they want 1200 to do it right. maybe less.... ask louis or nick about the pricing...i forget the exact number

rebuilding turbos is a waste of money unless you go with either the bnr set or the set from rotary reliability and racing's builder (they used turbo city for years and the majority of all their turbos came back leaking withing two weeks which led to a winning lawsuit against turbo city as i mentioned)

BNR has recieved very little complaints and has extensive knowledge of this set. they also do some decent upgrades. they have great customer service on these boards too...the best of any aftermarket parts company i believe.

the last time i was at turbo city to get questions answered the guy working there told me that he really hates rx7s turbos and that they have always had problems with them failing...he said he would sell me the cartriges though.

the above advice by redrotor is exactly right. get it done right or waste your money. I went thru 3 sets of turbos before i finally went m2.

ask bryan at bnr supercars to help you...or call rotary reliability.


or spend the 3k and get a set of m2 ballbearing twins...or jspec stockers....i prefer the m2 option for the performance gains.

new is honestly the smart way to go. put it away for a couple months and try to do it right...or rebuild every six months or less...its up to you.

I have seen at least one forum member with turbo city rebuilds have them work out. however...like i said...the majority fail and that is why turbo city lost their lawsuit last year and had to reimburse labor costs on their turbos installations.

btw...kwik has bnr turbos...and yes 750 is very cheap for quality work.

before rebuilding...i also tried getting them from these forums used....met with four different guys who said they had good turbos....all four sets were said to have no leaks

when i inspected the turbos i checked for oil residue deep in the snails...sure enough..oil...and leaks.

used is a gamble for sure.

I spoke with louis at rotary....if you want a good set you can give him a call. they are confident in their turbo builder to the point where they warrantee the labor if you do it there. and they hate pulling turbos again...so I trust that they have access to an excellent builder.

the number is in the above ranting post.

It took me forever to figure out what a Prive was.

 

Lastly ... if anyone decides to get their turbos rebuilt, for your own sake, make ABSOLUTELY sure that NEW carbon seals and either new or glass-beaded and cleaned turbine housings are used. Turbo rebuilders will try and re-use your old carbon seals and your oil-coked turbine housings ... that ol' replace and balance trick doesn't work on HT-12's. I've heard that the carbon seals are hard to come by now ... so good luck.

 

This is absolutly correct and I'd imagine any one charging $500 for a set of twins is NOT replacing the carbon seals as that alone would account for over half the price.

BNR replaces the carbon seals as well as some other stuff, I dont know what all spacifically.

If you buy used listed to artguy because he is dead on with the used turbos. More than likely they are junk, I'd say prob 85% of the time, more people dont even know they are riding around on junk turbos, the only real way to tell is if they pulled the turbos completely apart which 99% of the used turbos on the market have not been done. Even if they dont smoke if there were ever on a motor that cracked an apex seal I'd put money on the fact that 90% of the time the turbine wheels were **** after a motor poped. Turbine wheels dont tend to hold up agaist even a sliver of an apex seal when those wheels are moving 100,000+rpms.

My vote is BNR, i know Brian personally and I've been to his shop so I know what kind of work he does. His turbos will have a one year warrenty and he is very willing to take them back and fix any prob that should arise.......not likely though

Good luck,
STEPHEN

 

redrotor is right....and so is spo

i dont even think performance techniques opened my set up all the way...when i opened them the wheels were chipped to bits and black even though there was only about 1000 miles on them...it looked like something had gone thru them at first...but when i really looked you could see that they had been out of balance and that the heat was causing the fins to peel over and get brittle.....and that the balance problem was causing them to rub on the snails a bit...thus the dentist drill sound


this is the kind of thing you get when you go with cheap rebuilds...labor and parts on my CHEAP rebuilds cost me 3000 dollars and plenty of headaches...and even more downtime on the car...arguements on the phone...and frusteration.

get a good set...tis the only way.

ok, for BNR. I take them my car and they remove, rebuid, and reinstall the turbos for $750? or do i just send them the turbos? And if i have to send them the turbos, about how long does it take for amecanic to remove them? And where is BNR located? do they have a website?

 

I shot BNR an email a week or so back...BTW, its BNRsupercars.com. He said it would take 5 working days to rebuild turbos. My turbos have almost 42,000 miles and are very good. Been at stock boost levels till about 34-35K miles and then 13-14psi on up. I might just have mine rebuilt because all his rebuilds come with a ported wastegate, which I'd like to have.

 

yer looking at about 300-400 bucks to have a mechanic pull them

only take it to a reliable rotary mechanic. do not go to the dealer.

rebuild fees are on top of that.


that is why i said rotary reliability can do it for that price...i believe that includes labor


you will have to ship them to bnr in alabama?? for repairs otherwise. it sounds like two weeks worth of wait to me...

anyhow...thats yer two real options.


j

 

if you have rotary reliability do it they will warrantee the labor and the parts.

if you have a mechanic do the labor and you get the turbos yourself odds are the mechanic will NOT warrantee the labor.


j

 

Do it yourself. It's not the hardest thing to do on your car. 2 oil lines, 2 coolant lines, the mounts, and the manifold bolt ... the manifold bolt being the only bitch of it. Not because it's that hard to get to, but because it tends to wear and sometimes break. (That and it's still fookin' hot under there ...) And while you're in there, it's probably a good idea to replace those oil and coolant lines as they're probably worn and/or coated with gunk. BTW, those gaskets are NOT re-usable. If you have your mechanic do it, I'd still suggest to get this done. Better safe than sorry. (There's the hidden cost in replacing/rebuilding turbos ... Mazda charges a buttload for all these parts. ~$130 for both coolant lines, $530 for all the oil lines (5 parts), and all the gaskets ... roughly $1K.)

 

so do you think it owuld be possible for me (never working on a motor before) with regulay tools, to replace both rubos w/ maybe some good instruction guide? What do the gaskets do? and why are they not reusable?

 

i dont think it would be worth the headaches you would go through. take it to rotary reliability and racing and get it done. thats how you do it best. if any problems happen due to their fault they would fix it for free. if you screw it up you end up wasting many hours in the garage and end up even more pissed off.
