It's time to replace my turbo. After doing alot of research I am unable to find a place to rebuild my RX-6. So I will be buying a replacement turbo. Can someone tell me what turbo will be the best replacement for a rx-6. If possible I would like to keep the same Downpipe, and manifold. I was thinking about a td04 with a 1.00a/r hot side? I really want the same responce as the rx-6, But I would like to stay away from ball bearing turbo's. I know they are the fastest spooling but, I would like a turbo that is rebuildable.

I would go with a gt3045 But that's way to expensive and it's ball bearing. So what would be an allternate?

 

the rx6 spool pretty fast man . i dont think you will get another turbo to spool so quick and make the same top end with out ball bearings. i was gona say gt35r but you already elimated that.if you want a non ball bearing turbo that spools as quick you gona have to get something small and your gona sacrifice top end. and vice versa.

 

Does the Rx6 use a T4 footprint? I always thought the IHI hot side was a bit smaller.

 

I'm am pretty sure that a g3045 is a tad bit larger than a rx-6. I am in thr process of pulling off the turbo and manifold right now. The weird thing is, the turbo has no shaft play. I was under the impression that if a oil seal was blown the turbo would have substatial shaft play. The cold side has oil all over it but the shaft is nice and snug. And no marks from the wheel hitting the compresser housing. Any ideas?

 

there is no way to rebuild it???

this might b a stupid question but. do you have a vac line from teh oil filler neck going to the turbo inlet? b/c this is how the twins are and there is always some oil in there from the crankcase venting system.

 

I do actually. Think that could be the problem?

 

does the turbo still spinn freely and spool and hold boost good and everything?
if it does then i would think so .. if thats the case just get an oil catch can.

 

Turbo works perfectly, just shoots oil.

 

if it doesnt smoke out of the exhaust when you driving and when you start up. its fine. the turbo is good. just install an oil catch can in between dat vac line that goes to teh turbo inlet. and make sure your crank case ventilation system is working good. check the pcv valve. basicly whats hapeining is your oil pan gets pressureize under boost so it forces the oil in there to go to the path of least resistance, wich is the constant vacuume that the turbo inlet has. this is how mazda designed the system to work . just put an oil catch can .. congrats you dont need a new turbo.

 

RX6 has a TINY exhaust side. T25ish.

No garrett will just bolt on.

Get another RX6 if it really is bad, or weld a t3 flange on the manifold. Then the GT's will work. It is a very nice manifold and waistgate.

 

I do see smoke when starting it. Only for the first 10 seconds. And it will smoke a little at wide open trottle.

 

if it dont have any shaft play and it spools and olds good. then its a good turbo. wha color is the smoke when you start up. might just be fuel . and it might just b fuel when your wot also. from what you telling me i think your tubo is good and i would not mess with it. thats on of the fastest spooling single turbo for our cars.

 

Blue smoke in both instances

 

Cars probably just runnin rich. If its not like a smog cloud I wouldnt worry about it to much.

 

rich fuel smoke will be more black... blue is def oil. but its b/c of the oil geting sucked into the turbo from the filter neck and den being boosted back into the engine. disconect the vac line that we talked about earlier and clean out teh cold side of the turbo. go drive around and get on it good and den let the car cool, check the turbo to see if ther is oil in the turbo now. (im pretty sure there wont be any)if not then you are straight and its not your turbo. its the other thing we talked about...

 

I pulled of the hose. Tommorow I'm gonna drive it around with no intake and see what it does. Just a question though. What is the large intake hose going into the turbo inlet pipe. Not the one for the BOV, the other one the same size?

 

Good point on the smoke color. Haha, dont know what the **** i was thinkin. Works got me all tired.

 

the turbo inlet is only suppost to have 2 vac lines attached to it.

1- going to the oil filler neck(the one you are going to take out for the test drive.)

2- going to the oil metering pump injectors, on top of the rotor housings. (its just a vac. no oil goes threw this line.) .. if you are interested in eliminating both these lines just you can just let me know. its real easy.
