Is it possible, Or is it even worth the money to use a 87-88 turbo rebuild kit in an 86 NA engine?. What i plan on doing is buying an 86 na 13b engine. I want to totally strip it down and just build it up with some 89-92 rotors and bigger injectors and all that good stuff. any advice or someone just flat out telling me im wasting my money would be greatly appreciated.

yes, it's a waste of money especially if it has the turbo exhaust gaskets which cost you about $200 alone.

just get the kit for the series of engine that you plan to build it into.

^what he said.

For my S5 TII block I used a S4 N/A gasket set and then just bought the two gaskets I needed.

Thanks. Reason I ask about using a turbo rebuild kit is because I do plan on turboing it.

most of the gaskets still won't work for a 6 port motor so you will be piecing together 2 kits anyways, you would be better off just buying the turbo gaskets seperately.

the O-ring sets for s4 are the same part number turbo and non.

buy oring set, and intake and exhaust gaskets.

The o ring kits are all the same. Just order it thru RA. Only like 160 or so shipped

or less from atkins for their generic kits, which i can't find on their store for some reason. they like to try to push the master kits which are unnecessary. the generic kits come with OEM internal water seals, the RA coolant seals have a tendency to "itch" on the irons and fail after about 5 years of constant use, i only recommend them for racing applications and not DD uses.

my RA coolant seals have an internal water leak after about 5 years and 30k miles of use and reuse and most that i have pulled apart that had them the outer teflon coating was ripped in several spots on most engines. the RA type coolant seals(mcmaster carr) do have their pros which are reuse and higher melting point if you happen to overheat the engine but the large con is they can't take constant heat cycles over a long period of time and they are very difficult to work with in cold weather(even if you boil them they are pita to get into the metric coolant jackets since they are an SAE measurement seal.)
