Okay so I get my motor rebuilt and I am not sure if the motor I was given was a 13bt motor or 13b-rew... Please no flaming.

Are there certain markings that would indicate which is which???

Please help asap.

Why do you suspect you have a 13BT?

there should be n3a1 stamped in all the iron housings on an -rew

Because the guy that built my engine was a sleezy bastard!!! And I am not sure which one I have because I want to be able to run a microtech, so I need to know if it needs to be burned for a 13bt or 13brew...

But I am confused because he could have just used 13bt housing so... I just want to tell which CAS I need to use because I don't have one so I have to buy one and I need to know which one to get so I can have the microtech tuned for that one(Crank Angle Sensor)....

Where will this n3a1 be stamped??? on the top or what...

 

Simple, if it is blown it is a 13B-REW.

Check for rear motor mount bolts = 13BREW

Center motor mounting = 13bt

 

Well my original motor was blown so I am pretty sure that was a 13b-rew

But what do you mean by "check for rear motor mount bolts"??

and Center motor mounting??

 

Sorry to hear about the sleezy bastard.. These guys are hitting it on the head. Where and what shop built your motor?

 

The 13B-REW has motor mounts at the very rear, part of the mount actually gets bolted with the rear corners of the oil pan.
The 13Bt has motor mounts right in the middle. I believe they are actually bolted to the mid-housing.

 

Checked it it has "n3a1" stamped on the first iron housing.

What sleezy bastard built my motor. Well PM me if you really want to know. I am begining a lawsuit so I don't want to get myself into trouble. But the guy is not a very honest gentlemen. That is all I have to say.
