If your friend is having trouble holding his engine together, there's something very wrong. Every turbo Miata I have ever known, including mine, were as reliable and easy to boost as it gets. |
Really so all the stretching studs and other issues that people experience are normal for boosted motors.... Show me a factory manifold for the B that will fit and work properly in a miata.... Please I'm waiting

You won't find one because Mazda decided to not put the turbo on the Miata. But that's not what we're talking about. I was pointing out that the B-series was in fact, designed from the factory to be boosted. That is an irrefutable fact, just as the SR20 engine was designed with boost in mind.
As far as studs go, the problems stem from the Miata version of the B-series using the cheaper standard exhaust manifold studs because (wait for it) Mazda decided not to boost the motor in the Miata! If you really think that replacing manifold studs and buying an aftermarket manifold (of which there are plenty) are serious issues, you really should not be working on cars. But do tell what all these "issues" are that people have when boosting a Miata engine. Please, I'm waiting. |

https://www.miataturbo.net/attachmen...ine=1377842906 Lots of engines have problems with stretching exhaust manifold studs when racing. The key word being racing. Drifting and making mad pulls on teh steetz is not real racing, which is why its news to you. |

Well while this all funny ill chime in with my personal experience. A local older gentleman let me drive his sr20'swapped miata at an auto cross. It was stock internally with bolt ons with an s15 t28 and s15 6spd and I believe on an aem ecu. Guy claimed it put down 250+ on conservative boost. Car was fast in a straight line and was pretty responsive in terms of spool and hasty on/off throttle situations. That being said he paid a lot of money to have the swap done "right" by a local shop and while everything worked well and felt solid it just seemed like a lot of money for what you gain. To be fair one of the advantages I saw was the fact that an sr20det is designed for boost from the factory and thus there are torture tested OEM components that you don't have to worry about breaking or stretching or vibrating off or making relief cuts in. While I personally don't own a turbo miata I have a good friend who does and I've seen the great lengths he has to go through to make sure that everything is holding together reliably. At the same time if you're going to upgrade the motor I'd replace it with something either a bit more modern or significantly more powerful. Jut my .02

Please see: 323 GTX, Familia GTX, and Familia GTR. Also: Mazdaspeed Miata, Miata SE overseas, and various other special turbo editions. |
I'm well aware of that fact concealer. I understand that the motor with its low compression and oil squirters is designed for boost. I was referring to the fact that I don't see a factory manifold that fits the miata properly with the exception of perhaps the mazdaspeed one which still doesn't fit a 1.6.
Also I didn't realize that posting an opinion based on personal experience withthe very swap that OP asked about was an issue. I realize that this thread is a big joke to you long time members but I was just sharing info with the OP. please carry on posting eggplants. |

What does my experience with the swap have to do with anything? Isn't that what this thread was about? An sr20 swap?

No... what do the manifolds have to do with anything? |

He's from the Mitsubishi world. Factory manifold bolt on to pretty much any car and have zero issues with stretching studs and vibrating hardware.
The error in your assumption Martin, is that a factory manifold would solve these issues. It wouldn't. Keep the stud stretching talk and mazda engine stuff in the studs thread. And for the love of god don't bump that thread. |
