hey guys just tore apart my 1.3l engine and about to start cleaning it and replacing everything but I may need a new block, any suggestions on the cheapest most reliable place to get gaskets and parts.. also I would really love to swap the tranny from automatic to 5 speed manual I don't have a lot of experience so any good kits you have used or suggestions are helpful! I have a lot of parts to replace so would it be cheaper to just get a new motor?

Probably better to get a new engine, depending on what needs to be replaced, and might I recommend getting a B6? Bolts right in, and you'll have more power to work with.1990 L Plus Stock B3 automatic -scrapped- My First Festiva - RIP

b6 out of a miata? will there be any transmission issues?Comment

No transmission issues, as it is the same block as the B3 1.3L, just bored out to 1.6L. However, if you get a B6 DOHC like the one you described, you'll need a modified engine mount for the passenger side, and you might need other things, but I'll let someone else verify that. The B6 I have is a B6-ME out of a Mx3. Its a SOHC so I'm not sure about the DOHC implications, though there are plenty of threads out there if you search the site for them.
You can get a B6 from quite a few cars. Protege, 323, and the mx3 all have SOHC versions of the B6.
Here's for reference on Mazda B engines:

Hey Top,
I have a Dohc B6t in my daily driver. The install was fairly straight forward, but the wiring involved was easy but for a novice may have been a stumbling block..... There are swap guides for the Dohc swap and they all point out the wiring etc that is necessary You will need the ecu from the donor car and a most of the main wiring harness, they are different..... There is light fabrication work needed for the passenger side engine mount, but also laid out pretty well in the swap guides in the stickies on this site. Everything else bolts in.
On the other hand the Sohc B6 swap from any of the other above mentioned cars would be like putting another stock B3 in Same passenger side mount and all, they can be run with the stock ECM, same injectors and sensors, just swap over the parts from your engine to the donor then drop it back in place.
The swap from auto to stick is easiest done with those parts form a donor car. All the holes and everything are already stamped where they need to be just add the correct parts and you are done. You will want to get the shifter, bars to trans, trans, both axles and the pedal assembly from your donor Festiva.......
Good Luck.Last edited by red90festyonair; 10-01-2015, 02:56 PM.Comment
