Helping a friend with his 4Runner. His turbo took a dive and now he needs another. I just need info on where to get one, who has the best deal and a website would definitely help.

Thanks folks

garrett t3/t4 hybrid turbo it has been done

dcg9381

A garrett swap can be done with an adpater, but the flow characteristics of a garrett are likely to differ significantly from the CT20. Guys that I've seen do it typically end up messing with the EFI systems trying to get it right under part throttle. Also, the oil feed, water lines, and drain don't bolt on, you'll have to make some modifications.
I run a garrett hybrid, but there a lot of stock 22rte left in my rig.

The ct20 is small, expensive, hard to find.

My recommendation would be to bolt on a ct26 from a supra. It's a lot cheaper to find rebuilt, it will bolt on with mild modifications, and it'll flow significantly better than the stock CT20.

Make sure you add some flex tube to your downpipe setup, it make make the life of your turbo a lot longer. Part of the problem with the ct20 is the housing tends to crack. A hard exhaust system bolted to the turbo doesn't help.

Hey dcg9381. I think I remember you saying you were going to sell an adapter harness for a 22ret ecu to a megasquirt unit or something along those lines. Any updates?

dcg9381

Yes, I'm selling them. They're $150.
I also have the megasquirt units also, at $350. They're pre-programmed for toyota sensors. I setup baseline timing. Because I don't have a stock 22rte, I can't tune them for fuel up front, but I can provide a fuel map if you're willing to use 440cc 7mgte injectors.
Options are: with or without AFM, wideband or narrowband.

I'm backlogged with people wanting them and hopefully there will be a write up by someone independent in the next 30 days or so.

On the turbo - you could also send it in to have it rebuilt. I believe Majestic turbo services them (Waco, TX). Its best if you do it before it's completely gone. It can make a difference between a $100 repair (parts) and something that runs you $500-$900.

I'll definitely buy one from you in due time. I am going to use 450cc dsm injectors with afm, but I'm not sure if I'm going to go for a wideband yet. My wishlist keeps getting longer and I just bought another project car so I have to watch what I'm spending money on right now. If you can give me your email, I'll let you know when I can throw some money your way.

Also, If I decided to get rid of the afm later on, would I need to do any modifications to the unit or just have a shop reprogram it?

dcg9381

Or you can use 440cc Supra injectors, which are also cheap and fit in the manifold...

You can do this is stages, not that you need to buy anything like this right now. For project #2, I took a stock 22RE and had it running on megasquirt. I did it with the stock AFM, stock narrowband - basically as a proof of concept and then went from there when I built the turbo motor.

The AFM isn't used by megasquirt to calculate airflow.. The only reason the AFM would be necessary for what I do is to give you a little more plug and play. There is a stock air temperature sensor in the AFM box that gets used. If you remove it, you need to use a GM sensor in the manifold. The difference is 2 wires vs factory harness and a slight difference in programming.

Let me be clear on this - "shops" can't program this for you. At least not 99.5% of them. It's just like FAST or SDS, it's complete EFI replacement. You tune it yourself - or start with a base tune that I provide.


If you start with a narrowband and AFM and want to change that later, you absolutely can do that. It'd require a slight wiring change, which I can detail and "reprogramming" megasquirt which takes about a minute using a regular laptop.

If you want to run tunable EFI, you need to be committed to tuning it via laptop.. It's not hard, but it's not a turnkey operation... Anyone offering you a turnkey "custom tuned" deal that hasn't spend time on a dyno with YOUR vehicle is offering you snakeoil.
