Connors car came in for diag due to odd issues.
Rough start
Lumpy idle
Misfires
Timing codes
Valvetrain noise

The further we dug the more issues we found until we found the nail in the coffin. Enjoy the pictures because this kind of stuff is the reason why we suggest letting experienced people help you with your builds.
This engine was assembled wrong and unfortunately for the owner he was sold something unaware of the issues the previous owner created.

I trust a stock engine more than most self assembled (built) engines at this point.

Stick with the mazdaspeed engine builders or ask us who we prefer.

Carlos dropped his gen1 off with a slew of parts from his old speed.
We usually do not take customer supplied parts because of the headaches. (This car proved why)

We still returned him a banger on a STOCK ENGINE. **Customer requested we exceed the factory limitations. We advised against it and the customer assumed all responsibility**

Got spinny drank on the dyno today after resolving an oil pump failure that almost made me build another engine.
New turbo dropped in (bnr s5) and added port injection so I can run full e85.

Bnr s4 turbo for sale
New center section was installed by me.

This was in my car for 4k miles and I recently upgraded to an s5. So I put a new center section in it due to oil pressure concerns (engine).
Everything in the pictures is included and should be ready to drop in.

Evan C. Hotto dropped his engine off with a spin rod bearing.
We swapped in an Overspeed Motorsports stage 1 engine bnrs4 and some more goodies to compliment his already modified car.
Full Koni/ eibach/ cs/ spc suspension was also added to help with the increase in power.

Cyrus brought his BNR S3v5 MS3 in for a dyno tune
346/357 on 93 octane

This turbo hits hard and in our opinion what should have came on all mazdaspeeds. We are running deals on dyno tuning through the month of August. Pm us for scheduling.
