Beefing Up my Yaris

[RacerFreakXXX]

I've decided to go turbo after a lot of thinking. I'm not going for anything fancy but I want to get the job done right. My goal is to make 130-140whp, my goal spending limit will be $2,500 or less, and my goal time frame completion is summer 2011. I'm going to need your help to piece together what I need. This goal is not including gauges, electronics, EMS. I have a good idea on what needs to be done with all of that.

Here is what I have:

• ebay Intercooler - $50

Here is what I need:

• Garrett Dual Ball Bearing GT2554R $900
• Garms Bottom Mount Turbo Manifold $439
• Perrin Fuel Rail $180
• 1zz-fe Fuel Injectors $60 - $100
• Custom Piping - $500

So far my total is around $2,100 (playing it safe), so that gives me $400 for little things.


Questions:

-What GT25 Garrett turbo should I go with (basically what AR do I want)?

-What other turbochargers might you suggest for cheaper that are rebuilt or new?

-What are the little things I will need?

-What do you guys think of the XA/XB Ebay turbo manifolds?

-Are there any other bottom mount manifolds other than ebay, HKS, & Zage?

why don't you get the MI turbo manifold?

wow.... I missed that... thank you PETERPOOP. Now that's a lot more than I planned to spend.

management: hardware, wiring and tuning. what is your budget for that?

ems, wiring, gauges, ect I will figure out... it's the gaskets, lines and adaptors that I really need help figuring out. Oh and a downpipe to go with that turbo manifold of yours, lol.

[cali yaris]

are you going to run an external wastegate?

[cali yaris]

Garrett GT2554R is what I used, it was an awesome little turbo. I'll be using that one for the kit I'm making.

[RacerFreakXXX]

Well that's good, and it's cheaper than the GT2560R. So you will be selling an actual kit turbo within the next year or will it be a step by step and sell it when it's done?

[cali yaris]

I'll be selling parts as I make them and a complete kit when a stock test car drives around boosted for a month without CELs.

[RacerFreakXXX]

well I'd be happy to be your test car, lol

[PETERPOOP]

The MicroImage turbo kit, I believe, will also not have any management.

[cali yaris]

^ that is the goal.

racer, add a BOV to your list

[RacerFreakXXX]

I'm not 100% on the bov... I'm also trying to see if I can run a turbo at low boost with little to know help from an ems. What do you plan to include in your kit?

[cali yaris]

Why are you not 100% on a BOV?

Hi RacerFreak

Making a custom turbo setup is not easy and cheap as it seems. If you plan $2500 you might think of another $1000 for what you might forgot.

1. A BOV is not an option but a must so you must include that

2. Decide whether you are going internal or external wastegate. My opinion for low boost applications till 7psi, an internal wastegate of the Garrett turbo itself is good enough

3. Decide what intercooler fits best for your needs and looks. A top mount IC would be cheaper and is good for low boost while a front mount IC requires fitment, more expensive to buy but looks awesome. Don't forget the custom intercooler piping to add to the list.

4. Upgrading the fuel pump to a higher flow rate one is an insurance and might aswell need it to keep up fuel during boost. Also consider adding a fuel return line to the setup.

5. Also consider upgrading the fuel regulator to an aftermarket one

6. Maybe the stock clutch might hold but not for long. Try a stage 1 exedy clutch to be safe.

All parts can be cheap or expensive depending on brand and efficiency. My opinion is that to invest in quality parts as these are that assure your motor to work safe when you sometimes hit the gas more roughly

Hope this helps

1. A BOV is not a must for a stage 0/1... there are plenty of stock turbo cars w/o them, however I may get one.

2. I know I'm going to do an internal wastegate.

3. I already have a front mount intercooler.

4/5. The return line and pump are probably going to happen with this build and I may also use a fuel pressure regulator too.

6. I am planning on a clutch and a diff but those are not part of my turbo build, I was planning on that before I decided to go turbo.

I'm not planning on boosting like crazy, I just want something that can get me to my power goal. I'm not planning on winning any races or anything fancy like that. The Yaris just feels like it needs more power so I'm not always going through the gears to get the car up to speed.

My price is for a turbo build, not tuning and all the supporting mods. I am pricing this like a turbo kit. The average turbo kit is 3-3.5k with piggyback EMS and intercooler.

RacerFreak why don't you try to find a 1NZFE TRD edition if you want only 130HP. It comes turbo standard with factory management and wiring.

I know ppl who done this in our country and reached 150HP without much complications

What pump are you talking about?

and what FPR? I thought these were returnless fuel systems or whatever, need to modify it to use an FPR?

Also you can just run off the internal wastegated pressure, usually around 7-9 psi in most cases. Look up an SR20 turbo, it will fit the GT28 flange.

You can go to the junkyard and get a recirculating valve which you should get or even a BOV from a stock turbo DSM with the piping as well that comes with it. Very easy to take off and get.

If you are running intercooler piping, might as well, right?
