Series of unfortunate low funds
 
I have a 1981 Rx7 gsl that I swapped a 13bt and transmission from a 1989 Rx7. When I received the engine the ecu and harness was TRASH! So I decided to try and go old school and do a draw through turbo setup but with purchasing a house and having to get a new daily driver I'm having to scrap the turbo plan and run the engine naturally aspirated. I have a Weber dcoe 45 and an Atkins lake city style intake (really short runner meant for a 6 port) aside from finding someone willing to trade a N/A block for my turbo block, I need some help with tuning the carb for running it n/a. Any help would be appreciated.

running a turbo engine n/a will be way down on power than what a normal n/a engine will be due to the lower compression ratio rotors of the t2 engine. if that lake cities intake u have is indeed for a 6 port, it wont work on the turbo engine as it's 4 port. a complete stand alone setup would be the way to go for the 13bt, but they're not cheap unless u can find one used. or get a running n/a 6 port and swap that carb and intake onto it and change front cover to change over from the CAS to a distributor. which would have to be changed anyway to utilize the front mount for the 81.

I appreciate the help, I'm going to find a 6 port to swap.
