Besides getting the wastegate ported out, is there anything else that I could, should do if I am planning on making any power with the stockers. I have the chance to buy another set because mine are leaking bad. I want descent peroformance but i dont want to go crazy. Can I port/clip like the dsm guys do so much. Any places where I can read about this topic. Thanks All.

 

Are you just talking about getting a set of upgraded twins or rebuilding and modifying yours?

just playing with mine. not looking to rebuild... just modify a new pair that i may get

 

Well, take a look at that site, you can see the list of things they do to increase the power of the turbos.

 

youre nuts.

unless they change the shafts...larger wheels etc will just break em down to spinning leaking crap.

good luck

hehe

do a search..this topic has been hashed thru totally.

 

check the site for BNRsupercars. there is a direct link to their page on the ad banner at the top of the page, usually. their prices are hard to beat, and from what i hear, they do really good work too....

Uhhh....

(I posted the link for BNRSupercars in the second message.....)

 

I would be a little discerning when reading artguy's posts about stock turbos. He has had horrible luck with them and has a very sour taste in his mouth. As a result he will advise you to stay away from "stock junk" in any and all forms, at any cost.

Talk to Bryan (BNR Supercars) about his turbos. He knows his **** and does good work. BTW, a set of his twins just put down 386 rwhp @ 15 psi w/o turbine wheels clipped.

 

I had a long talk with Bryan tonight and am going with his Stage 2 upgrades. They go in July 23rd. He explained to me about his turbos and the time he spends balancing them. I'm shooting for 400 rwhp at 15-16 psi and I know I'll get it. It involves more than just porting like other turbo places do. So they flow 10% more air - so what. Most places like Pettit and SR Motorsports although they know their rotaries, they don't specialize in turbos. Bryan seems to know how to put together a good set of turbos. That 386 rwhp at 15 psi was also with bolt-ons and a PFS intercooler. With clipped wheels it would be another 10-15 rwhp. Running them parallel would be like running a T04S. I'm excited about them. Artguy's mad because he didn't get any warranty with those M2s of his that have been smoking. He's had a bad string of incidents with rebuilds. I'd talk to Bryan. After I post my dyno numbers this summer, I'm sure people will start upgrading since his prices are hard to beat.

 

I thought you we're selling your car, Barry?

 

After thinking about it and talking with my wife, I've got too much into it to turn around and give some idiot a great deal on a very clean and well built FD. Everything major has been replaced except the turbos and transmission - and the tranny is ok still. If anyone is married and has an FD, there's tension in the house sometimes when it comes to "The FD Fund". After the turbos I think the car will just dink and dunk me here and there.........hopefully

 

I've got a feeling that after the turbos it won't exactly be dink and dunk...more like, ummm...zoom zoom?

 

Was the engine ported? Other mods? Anyone have the dyno sheet? I would also like to know how they spool.

 

I don't believe that was with a streetport (386@15 psi) and it was also with the small PFS IC which only makes 13 rwhp. With a streetport, better IC, and clipped turbine wheels it would have made 400-425 rwhp at 15 psi - basically the same as a medium sized single.

 

Really??? Hmmm, maybe I don't want that RX6 now. If you would, could you have them post the dyno sheet and all the mods.
Would ceramic coating help at all?

 

Ummm, guys I put down 397rwhp@17psi and 407rwhp@17.8psi using my Garrett turbos which don't have oil problems 'cause they aren't ball bearings! Anyone who is coming to Greece this summer will see them run. BTW I do have a pair for sale-check out the European forum.

 

Uhhh....we must have been typing at the same time, or my page wasn't fully refreshed or something. sorry for the redundance...

 

I'm also willing to trade these turbos for a HaltechE6K+external wastegate.

 

hahahahahaha...every time I have to SWEAR that this is the last MOD.. After this I promise the car will be more reliable...hahahahaha. She calls my car the "money pit" and says I should have just bought a Z06. hahahaha, I feel your pain. I am going single (apex rx6) but I may send my twins to BNR as a, uhm, backup *cough*.

 

hey barry....come on out to cali and run me.

Ill eat you for breakfast.


hahaha

ps...there is a reason so many of us go thru turbos like mad.

Im not the only one who had turbo issues...when I visit the turbo builders in the area and two of three tell me the same things I found out then I rebuilt them (that they are prone to failure and that they refuse to modify them as they cannot handle the additional stress)...and when I call one of the top builders on the east coast for rx7s and ask what they would do in my shoes....and they tell me to go with a single or the ballbearing instead of the modified stockers. Another builder even told me that he refused to build or warrantee the rx twins...but he would sell me the cartriges.

Not only did I do my research...but I also experienced the junk first hand.

haha

Ill stick to my learning from experience and not to what the ads on some companies website explain. its common sense...thats all.


good luck with the rebuilds boys. I hope they work out for ya.

excuse my naievity.

Im not bitter either...just learned my lesson...I tell others cuz its just a waste of money to go with rebuilt stock cartriges. period. they often do NOT seal right..dont beleive me...call five builders and ask them. if you reach someone who knows..and not a salesman you will get an honest reply.

ask yourself why you need new turbos anway...

j

PS...how long do you think that stock set wil last you at fifteen lbs or more? heheheehe you should know better.

 

Art Guy. Whats up. You have had very bad luck on turbos. If you need help figuring out your smoke problem with the M2's, let me know. As for Barrys car, you better watch out! lol I have some secrets!!!!
take care,
Bryan

 

Does this BNR do trade ins?? I have a pair of stock turbos that I would like to upgrade? Nevermind -- just looked at the site.. nice
Unlimited if your oil lines are replaced? How much does that run.

 

I finally have my restrictor pills...no more leaking....will have the m2 large intercooler early this week and then will be doing the dyno tune....Ill post my numbers and my sheet...that way we can compare the rebuilt stock set to the m2 garrett gt30 ballistics...I plan on running fifteen lbs low and 18-19 lbs on the high setting.

Ill let ya know how it turns out.

Those numbers were on a "mild" street port. To me those numbers are not all that impressive. People have made those numbers with stock turbos. Rich makes 368 with stock turbos and a highflow. Some more aggressive porting, or a mp and Rich and others can make the same power at the same boost level. I don't know if I buy it. Yes for rebuilt, upgraded twins the price is hard to beat, but I would love to see the dyno sheet. Or see these turbo's make 400 hp @ 15 psi. Its not going to happen. Of course there are people using the stockers and upgrades making more power then some of the guys with singles.
I really want to the numbers on the M2's @ 15 psi. I bet you will be hard pressed to see over 380 hp. But I guess we will have to wait and see. Keep us updated and good luck on the numbers guys!
