Bridge Porting
#1
I have decided to bridge port my s4 13b and considering my lack of knowledge I have found someone that will do it for me, they are asking AU$1500, which is about US$800, it covers labour and replacement parts and the porting/pulling apart. Is this a decent deal or am i getting totally ripped? Also, this engine, in the future will hopefully be getting put into a 84/85 rx7, rather than my s1 ('79) is this a wise decision? Thanks

yea a good bridge port engine can produce about 320 hp with a 4" exhaust set up and cost about $5000-7000 a pop and last about 10,000 miles. The S4 don't take to porting that well and your going to have a hell of a time starting and idealing blow 2000 rpms. I hope you know what you are getting in to. If you have the money go for it.
