Default My miata SR20DET build

So everyone knows i had gotten a miata with a 13B turbo engine in it. So after ******* around with the rotary for 5 months i have had nothing but bad luck and problems. At this point the rotary is nothing but a money pit thats not worth it one bit.

After looking at the parts i had that i was able to sell i found i would have around 3500-5000 once everything sold. So i started to look into motors to do, with my power goals of 450-500whp. I looked into everything from the BP to the RB25DET and 1JZ. After spending a few days looking into what would be needed for all the motors i decided to go with the SR20DET. The reason i went for the SR20DET is the whole swap is 100lb less then the BP motor and the BP motor is with out the turbo parts. The other reason is The price to put a BP back in would coast more as i would need to buy a new subframe as the mounting spots have been modded to fit the rotary. The last main reason i like the SR20DET was the fact there is a lot of after market support for the motor and info on the motor. Also getting parts for the motor is easy as the Infinity G20 has a SR20DE in it just no turbo.

So today i ordered the motor after i sold a bunch of parts i ended up paying 1750.00 shipped to my door. There is a company that sells a kit to make it a bolt in kit. Im not going to buy the kit but i have been looking at photos i have found of the kit as the kit makes it so you can bolt the PPF to the SR20DET tranny. My plan is to copy the mount and then make motor mounts. The other thing i might have to to is make a rear sump oil pan and pick up witch should not be hard at all. Then just need to have a driveshaft made. I have a full restorations and metal shop with tools and materials to make everything with.

Im going start taking the rest of the stuff out of the engine bay so i can clean it and paint it. The silver in the engine bay just always looks dirty to me.

Here is how far i am at the moment.

So the motor came around 4PM today and after it got here i got hard at work. I got the motor into the garage and stripped the intake and exhaust manifold along with all the other crap. I dont plan to use the stock intake and exhaust manifolds im going to be changing them out with in the week. So i got the motor and trans slipped into the car for fitting. What i came to find was the front sump oil pan is going to need to be removed and a rear sump pan made. This shouldnt be so hard to do with some sheet metal and the factory pan. The factory pan is two parts the top part is aluminum and the lower part is steel im going to reuse the steel part so i dont need to make a spot for the drian. After i get all that done ill be able to see what i have to do for making engine mounts.

So today i woke up at 6AM went to miky Ds and got me 2 mic gridles then went to home depot. I got all the metal i would need for making mounts and an oil pan with new oil pick up. So i got back around 7-730AM took the motor and trans back out and unbolted the oil pan. Once i got it off i got to work on making a new oil pan and oil pick up. The reason i had to make a new pan and oil pick up is the SR20 is front sump and the problem with that is it hit the rack and sway bar. So after looking close at what i had i had to make the pan tight to the bottom of the motor in the front half and a deep well in the back half. I ended up having to channel the front part of the pan for the oil pick up. Once i got the oil pick up and pan done i got everything back into the car engine and trans. I got it all close to how i need to have it so i can start making the mounts tomorrow. Here are pics from today.
So yeah this was all done today and i only eat those 2 mic gridles

Loving the progress and the speed of it.

One thing: you better clean all that **** up before you start driving the car. the engine bay is a royal mess, and that's understandable during the fab/install time, but after that go to town on that sob with some simple green and a brush.

or I'll fly down there and beat you to death with my *****
