ct26 60-1 and 62-1 owners speak up

[supraaddict87]

I know many think the 60-1 and 62-1 induction wheels are too large for the ct26, but for a temperary power solution on a budget I feel its my best option. I would like to know from anyone who has owned one if the slight power increase to the 62-1 wheel is worth the extra stress it causes?

thanks,
mike

62-1 is a nice turbo, I have it and have put atleast 10k on it, still boosts strong.

 

[turboa7mgte]

I ran the 62-1 all last year.... For the Price it is a great turbo. Just make sure you Turbo Time your car so you can cool it down a bit.

 

[supra90turbo]

what is the average cost of a 62-1 upgrade?
and who will perform the upgrade?

 

[sathu]

Turbochargers.com does the upgrade but only at 60-1. I just bid on a ct26 upgrade on ebay for 520 and I have the choice of getting a 60-1 or a 62-1 when I do the payment. What is the different in power from a 60 and a 62?

And what is a good and cheap turbo timer to get also?

 

[turboa7mgte]

I got mine from Steve Vang out of Michagan.... he is a good guy and a supra owner

I have a 60-1 and I really can't complain. Boosts great, no problems whatsoever. I have only had it for a very short while though, so I cannot attest to its lifetime.

I think on the CT the 60-1 Vs 62-1 probubly willnot give you too much more power b/c the bottleneck is still the compressor housing. Making the wheel bigger will do some but not much unless the compressor was bigger to allow that wheel to move more air.

60-1 here. No problems yet. ~340rwhp @ 15psi. Hopefully we'll see what it does at 22psi on the 30th.

 

[Disced]

340 RWP @ 15... on a 60-1? Seems a little off? Can you list your mods for me? Was that on stock fuel?

 

[s turbo 87]

60-1 here...I havent really got a chance for it to spool up to its sweet spot yet. From what I hear, you can tell much of a difference over stock until about 14 psi. My favorite thing about it is that it still looks like a stock turbo.

What type of boost controller do you guys use for the 60-1?

 

[supra90mkiii]

I kno this isn't the same with everyone, but i'm stating my opinion, and what i've been through. I got my rebuilt ct with the 60-1 (no clip) finally on the car in March of this year. Now, I was still on the stock fuel system so i could only goto about 9-10psi before hitting fuel cut. i used a homemade manual boost controller. with less than 3000 miles on the turbo, it started making a whining noise whenever boost was being hit, any boost at all. I checked it out for shaft play, and there was a bit, enough to hit the sides of the turbo and make the noise. My mods are in my sig. I never took the car to the track, never beat up on it, and obviously since i was on the stock fuel system, I was only hitting 9-10 psi. I took my turbo off 2 weeks ago. It's for sale, no bent fins, none missing, probably can be rebuilt.

Also, a fellow Supra owner from Wisconsin warned me about his failing just before 3000miles, while i was at 1500miles. Right now i'm trying to find a stocker to hold me over till I get an SP turbo. Oh and the turbo was sent to PT in California.

The only way you could wear out an upgraded ct26 turbo in 3000 miles was if you had a poor oil supply to the turbo. I've got more then 25k miles on my PT 50trim and it sees 16-18psi daily, and as high as 25psi on the dyno. I don't even have coolant running to it, I just turbo time it religiously.

 

[Anomili]

I had a manual boost controller that spiked, but I replaced it with the Avc-R from Apexi. Again, no complaints from me.

That was me. It was not starved of oil. It fell prey to another high quality Toyota part: the accordian hose. Apparently 20 psi is enough to make an old accordian hose IMPLODE, sending dry rubber bits into my 100K rpm compressor wheel. It did not damage the housing, and does not have excessive shaft play.

Moral of my story? If you're paying for the upgraded ct...pay the extra 35 bucks for a new accordian hose. Mine was not cracked at all to begin with, but was still old enough to commit sepuku. :3d_frown:

 

[bigaaron]

Ok, now I feel better (but I do feel bad for you). No turbo, no matter who built it, can withstand kibbles and bits being fed through it. LOL I thought it was less likely to see poor quality PT work cause a failure then some unforseen accident like that.

 

[supraaddict87]

Is there a good way to "prime" the turbo before start up. The reason Im getting an upgrade is because after doing my headgasket the stock turbo started running out enough to rub the sides of the compressor housing and I beleive it was oil starvation. I only ran it a few min. and noticed I wasent getting the oil pressure I like and wanted to replace the oil pump. While in the process of doing so I noticed the turbo and pulled it of while it was still repairable. I dont want the same thing to happend to my upgrade.

 

[DrakeMK3]

You must prime the system if you want to get oil to the turbo before you start it. To do this, take out the EFI fuse located in the engine bay fuse panel and crank the car for somewhere between 10-15 seconds. This gets oil in all the necessary places before you actually start it.

I had a CT-26 upgrade and it ran fine while I had it. The spoolup is very quick because of the small turbine side. But if you are looking for nice topend power, a full T4 like the SP61GT or T3/T4 turbo will allow your engine to rev like you never thought a 7M could. The CT-26's hot side really chokes the at high RPM'S.
