06 Subaru WRX stock turbocharger - TD04L-13T is the model number. It is a high response, low lag unit that IMO is one of the best you can get for a Miata engine - even better than the commonly used T25 and Greddy turbochargers. You might even get away with not using an intercooler at low boost, though a turbo without intercooler is somewhat akin to unprotected sex. |

Oh man, I started to respond to some of the posts on the thread but realized there is just to many wrong comments. *disclaimer* Those reading this thread please do more research on the responses found here Some funny things I cought: 1. People saying use a t3/t4 turbo. Ummm.. You just quoted the frame size not the turbo itself. Common error. That would be like me saying run a book/+442 motor in your locost and you will have a good motor. You would then say "you just quoted me frame sizes not motors". 2. Water/Meth/alchy. Its good stuff. Please read more on it if interested then what is found in this thread. 3. I ran 13 psi on a 10:1 motor for over 20k and never had a problem. The owner after me is still doing this and I have no idea how many miles the car has now. Its all in the tuning. Gotta jet. J. R. |

I dont know if any one menentioned it as I just scanned the thread. That turbo is total junk you posted in the first post. Anything XS, SSAUTOCHROME, Turbo XS Power, etc is not a real turbo. They are paperweights. With that being said it is possible to get a decent turbo off of ebay for cheap if your looking for rebuilt Garrett units. You just have to know what your looking for and what car the turbo came off stock. I happened to have a monster t3/t4 that was good for like 600hp that I bought for $450 on ebay. It was just that a monster. Worked well on my 2.3l FE DOHC but not well on a smaller engine. For a miata you could get by with a small mitsu turbo like a 16g or something like that. As for inter cooler, use one off a stock 88-92 MX6 GT its a nice size for cheap. The manifold you post will work but it may crack in the future so you may have to weld it a few time. As for injectors Percision has really good injectors for cheap although you could try something like a 5th injector setup if you strapped for cash. Check out http://www.homemadeturbo.com evo |

If I were going homebrewed, I would use the turbo, turbine housing, exhaust head pipe flange, bov, and waste gate components from a Mitsubishi Eclipse. You stole my idea Look on page 2. |

Moti I was hoping to get it done for around $1500. |

I have heard that these chinese ebay manifolds are prone to cracking, but have never seen a case. I have heard that you can weld some sort of support structure to it to support the turbo and exhaust/intake tubing so that there is not any weight on it, this would be the best idea. |

A good inexpensive turbo that would probably work well for a miata engine would be saab turbo, I think its a t28 or t3 size which would be perfect for the smaller 4 cylinders, and they can usually be had in good condition for about $400. If cash is not too much of a concern I would recommend the "Disco Potato" which is made by garret and is very well reviewed in the tuner world from what I've seen. |

I broke the rule of not reading all the previous posts. I actually told myself I wasn't going to comment, since I wasn't into turbocharging anymore. I guess I can't help myself. |

Thanks, but in this thread K. Tanner says it doesn't work well on a Miata engine. After some Ebaying, it looks like the stock WRX turbo may be the way to go. |

Strictly "as cheap as you can get" speaking: Last I looked the KKK K03 turbo's were pretty cheap. You'd have to create your own manifold for it tho. Kinda small even for the miata 1.8L. But if you were going to stay low boost (I think not much more than 5-6psi). These are the stock turbos on some Audi/VW's (A4 and Passat) and usually cast aside by the power hungry for larger units. I havent looked in a while. |

Post subject: | Supercharge! |
Ok, this may be off topic and not the direction you want to go but I'll give it a shot. I have a Fastforward supercharger in my 2002 Miata. I love it. I will be supercharging my Locost with the same. (Project scheduled to start next year.) The kit is complete and is truely plug and play. There are several options for their kits, hotside, coldside yours would have to be a hotside I think because of the space limits on your intake side. Fuel management is with PC Pros. Prewired to plug right into your ECU. No intercooler needed because these use a fifth injector to cool the charge air and add fuel. Most importantly is the customer support is beyond any company out there. 24/7 guranteed. www.fastforwardsuperchargers.com |

I'd choose a turbo that has a flange that other miata friendly turbos exist in. Try to keep an upgrade path in mind, because I'll bet my shorts that the first turbo you're going to put on it won't be the last ... Moti |
