12a to 13b street port conversion

Hey all

I am planning on converting my 12a to a 13b street port sometime in the up coming months. A buddy of mine is taking his 13b out and swapping to a T2 so I decided to buy his old setup at a price I couldn't refuse. Expect many photos over the coming months of the progress of my second rx7.

Going with 48 Weber down draft. It's a whole setup from a buddy that is switching to a T2 in his car.

just a small update

Here is the Street port engine that is going to end up in my Roturd. Comes with 48 down draft webber with racing beat intake along with RB header and rebuilt transmission. Also have MSD ignition that will go on after the engine is installed and running good. Also going to be switching to a ebay radiator since mine has a broken mount.

This weekend I am planning on replacing all the door seals, all the radiator hoses and the radiator itself. I am replacing the rear brakes finally and also installing the Banzai racing dual pulley setup along with there alternator tensioner. Finally I will have working windshield wipers again hopefully as long as the switch works on the column. I will be taking photos of everything and will post them up on here Sunday or Monday.

Side note: I was wonder what size the stock wheel was so I had a good reference to pick out one from NRG.

Thanks Josh

Weekend update

So I got everything installed that I had ordered. Sadly I got the rear brakes off and the pin in the caliper is froze up so I am ordering new calipers to go on this weekend. Ebay special radiator works well and fit well. Here is what I got done:

Banzai racing dual pulley set
A/C working
Wiper motor
Radiator with new hoses

Things left to do:
Door seals
Rear Brakes
Alignment
Engine Swap

Here are some photos for people that want to see.

Here is a video of my last autoX run this past weekend. I ended up somewhere in the middle of the pack with tires that aren't anything special.

I ordered a clutch today for the motor going into the car. From here the car is almost ready for the new motor. I plan on doing the swap in May.

Today the spending continues. I bought a universal Racing Beat 2.5" muffler and the K&N Weber IDA kit for my turd. RB is expensive but this is the end of the purchases that I have to make for the car. Whoooooo!!!!!!!

Next time I will see the car will be at the next AX. Then it will be on a trailer back to where I live for the swap.

Got some a little done this weekend

Just dropping in to show the work I got done on the headers this weekend. They had some surface rust that wasn't going to come off so I scrubbed them down and painted them black with 2000 degree rattle paint. They turned out nice and should look great in the bay next to the motor.



Headers before



Headers after

Quick video from last weekend at AutoX. Came 3rd overall in my class but on my last fun run ended up running faster than anyone in my class.

Went and did some more autocross a couple of weekends ago. Fun time especially since it rained while we were on lunch break and changed the course feel up dramatically.

Here are both of my good runs.

Run after the rain.

So the amount of parts I have laying around is starting to get out of hand. I am getting excited for the swap and hopefully will be coming up soon. Here is a preview of some of the parts I have.
