Alright i know the first reaction most of you will have is to tell me how inapropriatley sized this turbo is for a 1.6l or even for a 1.8. I do understand that the turbo would not work well for what most of you do, and it may even be a little big for what i want to do but it will get the job done.

what i have is a holset hy35 with the .65 AR t3 housing.
I need to know how much room i will have with the ebay cast taco taco manifold. The compressor housing on this turbo is huge and i dont want to buy a manifold for my 1.6 and have it not fit.

 

Don't build setup around turbo. Especially one you already know is inappropriately sized from the get-go.

 

sell turbo, buy 1.8L.

 

I already have a bp4w sitting in my garage. The only reason i am not sure about swapping it is because its dificult to source a reasonably priced t3 manifold. Yes i know the DOC manifold for 759 is not unreasonably priced but it does not fit my budget, a treadstone DIY log may be the route i go.
Also dont the bps and b6s have the same rods? and the rods are the weakest link from what i understand. This would suggest that the 1.6l is stronger since it has a lower rod ratio. Then again with the larger valves and better head flow the bp4w may very well be able to handle a little more power since it can get the spent combustion out soo much more easily.

 

Its not stronger. Its not "anything" actually. Its inferior in every way. If you have a BP4W its not even a question of which motor you should use.

And you'll have to build either way if you want to use a big ol holset on a miata engine.

 

meh..

 

There is some good input here. You should ignore all of it.

 

Don't do it unless you have baller everything. Your block will ******* break in half.

You have the better motor sitting in your garage. Stop being a cheap ***.
