Please, please
Talk me out of a Nissan SR20det or CA18det swap. I have 2 fb rx7's, an 83 and an 84 both GSL'S i am looking to turbo at the least 1 of them and part out the other.. one has a racing beat full street port setup... holley carb, intake, header, and street port but it has a clunking sound when running. Not sure if its a broken stationary gear tooth or a apex seal has let go and imbedded itself in the rotor.. or some other issue. could be something as stupid as a nut or some other piece dropped in the intake. idles fine, still has power so i doubt it's a seal. But the shell is from MD and has a good amount of rust.. what other conditions could cause a clunking sound? I will post audio of the sound as soon as i can record it.
The clunking sound was present before i purchased the car, disappeared when i test drove it and reappeared after about 200 miles. i haven't started or driven it in 2 years or so and assume it will have disappeared again
The other gsl is bone stock, runs but idles high, around 2k.. I have a rebuild kit for the nikki but haven't dove into it yet. was originally from Arizona so the body is in much better shape.
I am looking for a 13 second, high 12 second car on the quarter with a bit of autox to go with it.
A tII swap is not out of the question but it seems parts are getting harder and harder to find, and not being able to rebuild a tII trans completely is disheartening
The 12a is pretty much dead from what i read when trying to rebuild and find new parts.
i'd love to keep it true to heart, but an sr20 or ca18 is starting too look very attractive.
SR because turbo motors are way more fun than say a chevy or ford v8, and i am a bit more familiar with a pist-on motor

Thats assuming the housings are still viable, and i read that b port makes the motor less reliable- less longevity because the seals have to run over a bigger gap. I am looking for 300+ whp which i can get 50K+miles before a rebuild.. if the 12a is viable, how much more will the rebuild be in 3 years if parts are already impossible to find.. this is the dilemma. a tII s4 or 5 is much better for finding parts at the present. and from what i read they will run forever on a properly tuned 300whp setup
