Hi all fellow rx7 enthusiast I run into a dead end on my project looking for some info I own a 88 rx7 s4 n/a that's been turbo and bridge ported Tranny is a n/a I just install the t2 rear and axles I purchase a s4 t2 tranny currently at Trans place been inspected, I had the t2 flywheel clean and resurface and the counter weight all 3 parts I purchase from the same guy who guaranty is all t2 s4.
My question is is there any marking on the these parts that will confirm these are s4 t2 parts to make sure before i install them in my car and finish my 2 year project.
Any info will be appreciated.
Thank you in advance.

 

Counterweight just needs to be S4 series for your S4 engine.
The trans will have a bolt on bell housing.N/A's do not have a bolt on bell housing.
You should be able to find specs on the flywheel diameter and go from there.
You need a T2 starter and T2 Clutch slave cylinder.

 

thanks misterstyx69 correct me if I'm wrong I need to replace the na s4 counter weight with the t2 s4 counter weight? Or can I just use the na s4 that's on the engine now?

 

s4 manual counter weight is a s4 manual counter weight, it doesn't matter if its n/a or turbo

the only time it gets different is between auto and manual, if you want a lightweight flywheel, you need a s4 AUTO counterweight

 

Hi Iduley thank you for the info that help clear all daughts about the counter weight. & Thanks you misterstyx69 also for your help. Great this makes my job a lot easier
