Thread: SS M90 kit worth it??

NO!!!!

You can top swap with all the normal stuff from a gtp way cheaper

The only thing on that list I would keep is the ported blower. Otherwise just get everything off of a GTP. You only need fuel logs if you go intercooled.

Now im top swapping with the mods above for far less than $1200

Better gains from top swapping? Please explain this.If you mean better gains per dollar MAYBE..... Price isnt going to be much different from one to the other all things being equal. You have to remember it comes with ported blower,lim and fuel logs,and a custom tune to your setup. You can also hack up your stock rails and run them if you wish and save 450 bucks and skip the logs. You also save some money on gaskets and alot on labor(if you cannot do it yourself) If you go ssm90 be sure to pick up a cheap core for the blower to save about 300-400 more

Another advantage is you are not relying on used or high mileage parts. You know your cars history(this is why I SSm90ed as opposed to topswap.

To run a 3.8 pulley on your l36 Id recommend headers or atleast a plog. Oh and be sure you have some sort of scan tool

why the SSM90 kit sucks (in my opinion):

- single belt setup
- can only run an SSIC because of [edit: injectors, i guess]
- the pulleys are way more expensive and hard to find
- you are limited to pulley sizes and you'll eventually run out of room to grow
- the price tag

if you can get over those things, then you'll be just fine with an SSM90 kit. otherwise if you want to actually go somewhere with your setup a top swap is much more capable of supporting an actual build.

People have run full size Ic's on the SSm90 kits. Its not hood clearance Rather Injector clearance issues. W body stores fullsize fits with little alittle modification. Single belt set up isnt as bad as everyone thinks, Ive run the 3.25 with no slip or issues. Im currently running a 3.4 with no slip(had to much knock for the 3.25)

You can switch to a GTP pulley set up rather cheap. But yeah you are limited to a 3.25 pulley if you use the single belt setup.(which is like a 2.9 or 3.0 gtp pulley)

either way, id feel better off spending money on other things besides just the ssm90 kit. for the price of it you can cam your car at the same time as a top swap and take it much further.
