[Mk2] [Turbo] Rev3 - CT20b v CT26 hybrid v CT20b hybrid

[Nic]

So it should for the price. The ct20b is still the best all round turbo for the stock fuel system IMO. You could buy four of them for the price of a gt28 + bits needing to have it fitted.

If you are comparing new prices I suspect there isn't that much between them. If I had to replace my turbo, I'd want to replace it with a brand new unit. I know I could fit a rebuilt/hyrbid stock turbo but from past experience these can often fail prematurely. Rather buy a new CT20b from Toyota I would spend the money instead on a GT28RS (along with the adapters and lines) which should make similar power to the CT20b but be far more responsive.

Gotta love the CT20b, It has a very useful range of torque for road use or sprints. It works well on longer duration cams too.

Often end up swapping between my big Hybrid and the CT20 as both are simple bolt on etc depending on what I'm using the car for.

I normally run the CT20 at 1.5 bar with a -31 actuator and its pretty darn good tbh. Only had a issue with one of my CT20's but other than that....

The Celica version is the one to have I believe, I stripped one of mine and it had a 360 brg, dont know if that's normal or not.

The new CT21 that banding about sounds like a plan, I've seen some info on the net and wouldn't mind trying one.

I gave Owens a call today to see what kind of money the Garrett turbos are for an MR2. I didn't get the answer I was expecting (maybe because I chose the general sales option on the switchboard?).

I asked an open ended question about what they had for an MR2.
This guy said they don't do anything for Toyotas any more and swiftly referred me to another company, CR Turbo, for a bolt on turbo, even giving me the phone number.
I asked again making it clearer I was open to suggestions of alternative turbos. He said they could make up a hybrid and adaptor etc etc, and without even giving any details of what that turbo might be or of the cost, I was being referred to CR Turbo again for a bolt on replacement.

There are no Garrett turbos that will bolt on in place of a CT20b as the flanges on the turbine housing are unique to Toyota. A GT28RS requires an adapter that fits between the stock exhaust manifold and the T25 turbine flange and another adapter between the turbine housing and downpipe or a modified downpipe. The GT28RS also needs water and oil lines.

There are a few places that do kits, or you can buy the adapters and lines separately.

Yes the GTX28, but the right one

What would be the right one?

http://www.turbobygarrett.com/turbobyga ... r#GTX2860R

Looks interesting, although not sure which of the several housing options would be needed, and a fitting kit. Not found anywhere online in the UK with prices. Some prices on the US sites, and I guess there would be import duty on top of that, so still not sure what the ball park figure would be for all the parts to fit this. Owens are a Garrett distributor, and as per my earlier post, they were more interested in referring me elsewhere for a bolt on replacement turbo.

I will get a price for you.

[rev3turbo]

Bob, do you supply full kits ready to fit on the 3sgte.. such as a GTX3076, if so... price?

Please PM me what you want and I will see what I can do.

If you are comparing new prices I suspect there isn't that much between them.

About 10 years ago they were really, really affordable. I paid £750 from Toyota, for a new steel wheeled ct20b from the UK/AU/NZ spec ST205 GT-Four.

My point was that you could buy two ct20bs second hand, and put the change to much better use elsewhere and still have the same power.

power delivery is much better on the modern turbos though. Like night and day in my opinion.

Looking forward to fitting sheppys/martin f's hks td05 to my car .. all the power of a ct20b .. but much cooler running, more stable and much more consistent ... 1.0/1.1bar should see a very reliable 300+ hp ... looking forward to fitting it


In summery it should flow better than a ct20b .. I hope

from all the dyno vids and stuff i've looked at it's a great improvement over a ct20 man
Looking forward to seeing your results with it.

[2mad]

Me too sheppy .. so looking forward to seeing whats what ... will defiantly post how i get on

[jimGTS]

they were more interested in referring me elsewhere for a bolt on replacement turbo.

this is because they dont sell KITS for the mr2. and none of their turbos are bolt onto a mr2 manifold.

theyll sell you any turbo you like, but as far as adapters/downpipes, afaik, that is not part of their business.

Mine felt better than a ct20b but with slightly slower spool, with the billet compressor wheel it feels very simmilar to a ct20 spool wise.

I guess ill find out how much power I make when the new downpipe goes on along with the power fc and wideband.

Although I was never realy looking for big power, just somehting nice with good characteristics for driving on a track.

Plus the mitsu turbos are way more common, easier to fix and people actualy make upgrades for them.

I've heard this too, supposedly popular in the states, Billet wheel would make a huge difference, The video in the link above doesn't appear to spool slower than a CT20 though, bearing in mind the video is the actual unit in question

Bear in mind my turbo initialy failed after a few miles of driving on the road and one trackday. So it probably wasnt in the greatest of condition when I bought it

ah, well that's (terrible news for you) good news for 2Mad then as the one I sold seems solid

but back on topic, the gtx series turbos blow the old toyotas turbos away!

Ha, didnt know that .. that vid really sold me on the idea (gota love youtube) ... I think i'll port the wastegate to minimize boost creep .. and see what it can do .. so cant wait
