Where do I find a non intercooled turbo?

[XSubsailor]

I've got a 1985 Conquest in USA. All stock. 92000 miles. Been my baby since 1987. I've heard a couple options. 1) Send my turbo housing to Top End performance and have it machined and mated to a 14G. 2) Find a turbo from an 86 or newer Conquest/Starion and switch the housings around. 3) Find a salvage car and get the intercooler stuff off of it. 4) Get a complete T3/T4 turbo kit, intercooler manifold and all (given the age I'm not sure my car can take the extra boost)

 

I'd also like to know if I have a TD05-12a turbo or a TD04-9a

i would buy a new Center Rotating Assy for any stock quest turbo and just bolt on the housings you already have (unless they are trashed). should be about 475 from turbochargers.com or forcedperformance.com

all quests came with a td05 12a - intercooled or non

[XSubsailor]

tubochargers.com says that the center rotating assy. are almost non-existant now....They sell a 14g, but it's intercooled. He's not sure if it'll mate up to what I have. I'll try the forced performance.com next. Thanks

The cartridge and wheels for both will swap. The non water cooled housings were only on 83s and early 84s. Never was a TD04 shaft in these over here. You can just get any TD05-12a cartridge and use it with what you have already.

 

You can put the rebuilt kit in yourself why pay them to do it? You have to remove it anyway and the only other part to take off is the nut from the turbine shaft and a small snap ring behind it. Just get the correct kit for your cartridge so tear it apart and look to see but it should have the two bearings inside meaning you can just swap it with a cartridge from an 86-89.

i just got owned LOL

[XSubsailor]

Ok forced performance got back to me. They say they also sell a 14G and that it'll bolt right on. I explained that I don't have an intercooler and they said it doesn't matter. (are they serious?)

I'm not up to really rebuilding this myself. I love my car but that may be over my head. I'll have to check with my mechanic to see if he's comfortable rebuilding the turbo.

Anybody had luck rebuilding?

Anybody had any luck with these aftermarket intercooler kits?

 

This one says it's oil cooled:

I love the diagrams though. Thanks guys.

The factory upgrade 14g is a good turbo because the exhuast side is better flowing than stock also. But, it won't work as non-intercooled without some modification.

 

This rebuilt 12a is a good deal. Only catch is it is oil only. The early cars were oil only and there was a builitin to replace them with the oil/water turbos late in 84. It will work, but it'll be harder on your oil and might not last as long as a watercooled unit. One of my flatbodies came with an oil only turbo, and it made it to about 90K before blowing a seal.

 

Ok forced performance got back to me. They say they also sell a 14G and that it'll bolt right on. I explained that I don't have an intercooler and they said it doesn't matter. (are they serious?)

 

[XSubsailor]

I thought all quests came with a td05 12a - intercooled or non in North America?

 

The rebuilt 12a you speak of is a TC05. Will it fit?

 

If there was a builitin to replace them with the oil/water turbos late in 84. I can't imagine they put in intercoolers for these new turbos. I must be missing something. My car is 1985 and has no intercooler. (When I bought it in 1987 the salesman pointed to the oil cooler and said that was an intercooler. Shows what I know. But I'm learning)

 

I found this:

http://starion.mrbdesign.com.au/turbos.html

 

It looks like the difference is just the size of the compressor housing?

 

I'm more interested in something that'll just work, sooner rather than later. The car has been parked in a snow bank since December. The turbo has a bit of a rattle which has me worried.

 

If I get a turbo different than I already have, I would need different oil lines too right?

[Komeuppance]

Yes, all US spec Starions came with a td05-12a. Early 83 Starions came with a tc05-12a, no water cooling.

 

The solution to your problem is very simple. Buy any used stock turbo from here and take your compressor cover(the aluminum part at the front of the turbo) and swap it on. It's a very simple operation to change the compressor cover, you just need a good pair of snap ring pliers for the big snap ring that holds it on.

 

You will not have to change any lines, as the td05 CHRA (Center section) is a standard platform.

[XSubsailor]

Thank You Robert. I like simple solutions. It sounds like from 83-84 they had TC05-12a in North America (oil cooled) Then in 85 they went to the TD05-12a some were oil cooled (mine) some water cooled (esi). The water cooled design stayed around until 89 I guess. I've got a model that's a bit of an exception I guess.

Some of the terminology had me confused. TD05-12A TC,TD05-12A 49178-01700 Turbocharger YF FR DASH,and TD05-12A 49178-01900 Turbocharger YF DASH DO.

 

I dont know what TC YF FR Dash or Dash Do mean.

 

It sounds like Mike's suggestion for the rebuilt TC05-12a is a good one and the price is right too.

 

Thank You all

I wouldn't use that TC05, personally. There was a TSB(Technical Service Bulletin) recall on those to be switched to the water cooled, dual bearing, TD05. Also, you're going to have to block off your coolant lines to the turbo. But it should work.

 

Do you have an ESI or an ES?? 4 lug or 5 lug wheels??

4 lug wheels. I don't have an intercooler so I shouldn't have to worry about water lines right?

[MikeMeyerhoff]

Ha we're all getting a bit confused here. Your car did come with an oil&water turbo. If you used that turbo I linked to you'd have to plug off your existing water lines because its an oil only turbo.

 

The oil and water part has nothing to do with intercoolers or lack of an intercooler. Whether or not you have an intercooler does effect the compressor housing part of the turbo.

 

So there are the following starquest factory turbos:

 

TC05-12a non-intercooled oil only turbos found on 83s and early 84s that did not get the TSB update

TD05-12a non-intercooled oil&water turbos found on most flatbodies (whats on your car)

TD05-12a intercooled oil&water turbos found on all widebodies and the 85.5 intercooled flatties

TD05h-14g intercooled oil&water turbos offered as a factory upgraded.

 

 

Having a turbo shop rebuild your existing turbo will be about $350. If you can't do without your car for a couple of weeks, but a rebuildable core from someone on here to send to the shop. I might even have one if I start digging.

[XSubsailor]

Great, I already hit "buy it now" yesterday. I hope they let me out of it, I haven't paid yet.

 

How about buying this:

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=120458064504&viewitem=&sspagename=STRK%3AMEWAX%3AIT

 

Then just doing Robert's idea of switching the housings? What the hell does the TC mean on the description?

[JohnnyWadd]

Rebuild it.

[Komeuppance]

Just block off your water lines and run that turbo you just bought, you'll be fine. Just make sure you allow the engine to idle for a minute or so before shutting it off.

[Tim_C.]

Also, it is my experience that all non-intercooled models '83, '84, '85, had the TC05 marking on the compressor housing. The '84 and '85 were the original turbo with the water coolant lines on them (or a dealer swapped one as per the SB?). Point is that all turbos with the TC05 marking on them that I have seen, also had the water coolant lines. I couldn't say for sure about the '83 because I've never had the original engine set-up for that year even though I own and drive 2 of them. Niether one had the original turbo with/on it. I'll take Indiana's and others words that all '83s were oil only.

 

I any event, like Robert said, you can get just about any StarQuest turbo and put your front compressor housing on it. The one in the ebay pic is not clocked correctly for any StarQuest to my knowledge. I would say that your current turbo has the water coolant lines. I've personally never seen a post '83 model year without them.

 

Dash is for the 2.0L DASH engine that is very rare and had valve and injectors/throttle body that were unique to it. I think it was Japan only, but not totally sure about that.

[XSubsailor]

The guys at turbo city let me out of the deal. So I'm back to square one.

[XSubsailor]

Are you saying that this one is not clocked correctly or the oil cooled one I almost bought?

 

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=120458064504&viewitem=&sspagename=STRK%3AMEWAX%3AIT

[Komeuppance]

It's not clocked correctly. Looks like they just put it on wrong as the bolt holes for the actuator don't line up with the wastegate. Plus, it's an intercooled turbo.

 

This one will work(it says TC05 but clearly has threaded holes for coolant lines, so it's probably a TD05 CHRA):

http://cgi.ebay.com/ebaymotors/Mitsubishi-Starion-2-6-L-Turbo-49168-01600-MHITC05-12A-/260736688098?pt=Motors_Car_Truck_Parts_Accessories&hash=item3cb51e1fe2

 

So will this, but you'll need to swap compressor covers, also 177 is too much:

I don't think that one is clocked correctly for any car, let alone a S/Q. the intake is pointed directly back at the exhaust?

[Metric-man]

TC05-12A's where at least up to June of 85 (1986 model year non-intercooled) probably some 87 non intercooled also,

and all were water-cooled after 84. A single bearing cartridge from a TC05-12A will fit inside a TD05-12A housing and vise versa.

 

Basically the only difference is Mitsubishi Heavy Industries 12A's went from a single bearing to a twin bearing,

and the clocking degree of the compressor housing between the intercooled and non-intercooled cars.

They will both bolt on to a stock Starion/Conquest turbocharger exhaust manifold.

 

I wonder if the 85.5 was the first to use the TD0C or if they had a factory optioned 14B back then ?

TD05-9A's were used on the 6G72 3000gt / stealth twin turbo, the early US mirage turbos used TC04-098

http://img696.imageshack.us/img696/809/tbifuelturbocharging027.jpg

So you could use as a rule; intercooled turbochargers were TD05's and non-intercooled turbos were TC05's.

[XSubsailor]

Ok that makes sense now. My turbo says MHITC05-12A 49168-01600 on it. At least a TD05 is an option by swapping the compressor housings.

[XSubsailor]

Just wondering. People always seem to talk about "shaft play". Is that what is causing the rattling noise when mine engages? Does that possibly mean my housing may be ruined?
