I like this build, but it sucks to have read about the problems you've had along the way!

Build is very well done. My only critique is why the hell did you go with the msm turbo when you built the engine. I have an msm and the only thing stopping me from upgrading is the fact that my bottom end is stock. You should have atleast put an ebay t25 on there so that you could upgrade to an EFR or 2871/76 later, The stock msm manifold is shit and has that stupid IHI footprint that is compatible with nothing. Otherwise I am jelly as my car needs a built engine.

Agreed with Ryan on all counts. You'll probably upgrade to a better turbo soon anyway lol.
Good job on everything else though. |
how do you like that bluetooth board? I was thinking of doing the same, but wanted someones thoughts on it, as well as how they did it before I took the plunge.

I'd phrase it more like this: Why would you go with the MSM turbo when you built the engine when those turbos are known for crap power output and a high failure rate? |
Jesus Christ, where'd you find the time to write all that!?!?
Great job Justin, I had no idea you had that much work into it. C |

The spool is never what bothered me about the setup. It is the fact that the manifold has terrible flow and the most you can push out of the turbo is 220-230whp and that is really pushing it with a lot of excess heat.

I saw that you went from the Super 60 to a T28 chinacharger, but I sense ambivalence since you lost a bit of the top-end but also crave the quicker spool for streetability. I’ll probably wind up with a regular garrett 60 trim myself (unless you want to sell your old turbo, lol) on account of the 1.8 over your 1.6. I really liked that dyno comparison between the two turbos…not quite sure I have enough faith in china products…yet. I went from a genuine Garrett T3 Super 60 (~48mm/60mm) to a replica chinacharger T3 50 trim (~43mm/60mm). https://www.miataturbo.net/attachmen...ine=1357663225 The difference between a super 60 and regular 60 trim is like .08mm on the inducer. But yes, I'd keep the larger installed if I had a 1.8L and could actually spool a tiny turbo. |
Great build man, loving the details. I have to agree on the turbo setup fail though, but it sounds like you are well aware of this and plan on upgrading.
Keep us updated as you go. This thing needs a real turbo :P |

compressor maps are silly; this assumes that you'll hit 15psi at ~140CFM. that's a big assumption.

I'm not going to pretend that I fully understand compressor or turbine maps, but in the pursuit of a more scientific approach these calculators have helped me in the past (albeit somewhat optimistic/inaccurate). |
