Built Engine, No Start Help
Hello all... Creating this as a follow up to my post in my build thread.
https://www.miataturbo.net/build-thr...mkturbo-90263/
Hoping someone could give some additional direction so i can maybe get the car running tomorrow.
My car is currently sitting at the shop waiting to be started for the first time.
Timing belt has been verified on both the damper side and head., The Crank Position Sensor was slightly off and re-aligned by the shop. Fuel lines are correct. When cranking with the timing light the mechanic said the light was no where near tdc. no start.
There's New spark plugs and the only thing that has changed really is the ati damper with the 4 tooth trigger wheel. I have verified that it is installed correctly.
What do i need to look for ?
Someone suggested cas in my thread - i am going to look into that further as i brought that up with the mechanic and he said that shouldn't make too big of a difference.
Just want to make sure the car gets up and running

Not really - I verified at the shop that exact thing - I will take some additional pictures tomorrow on it but i have some from the build - it was slightly off - but i have confirmed they are lined up correctly today aswell while i was at the shop.
I am using the same CAS from my old engine - i did not mark it - not even sure what that means but it was said on my thread.
MSQ is attached (this was old tune. but pretty much the same thing.)

Lars got it. Shop installed the cam gears on the cams wrong. You can actually see the lobes behind the gears in your photo - it's a little hard to picture but look at the visible lobes right behind the gears and then note their location in relation to the cam caps. Those are the #1 cyl lobes, and they are pointed at each other. They're supposed to be pointing away from each other.
The index pin on each cam will go in the slot for the corresponding cam. Intake cam pin goes in the "I" slot, exhaust cam goes in the "E" slot. Right now, your intake cam is in the E slot and your exhaust cam is in the I slot.

I got pretty excited the moment i saw lars reply because i know he was onto something.
Cam gears were installed by yours truly not the shop (they are actually pretty awesome) - I'm just now understanding what i did - I will give them a call in the morning and run over there with the update tomorrow thank you all.
