this iron garbage?...
 

last night did some porting, on my front iron (mediumish streetport pineapple racing)
and i noticed the coolant wall between the coolant passage and the inner coolant seal is fairly thin around the intake port, im hoping this is still usable as front turbo plates are becoming hard to find in good shape.https://cimg5.ibsrv.net/gimg/www.rx7...a783368234.jpg
