FS in SO CAL - RB S7 nearly new
This is a RB S7 with only 7 tanks run through it.The first 4 were static break in, and the last three were done in a parking lot. The mechanical bind these come with new is now gone. You should be able to throw this in your car, fire it up and go.
This is a backup motor that I wanted to have ready to throw in the car if needed, which is why I did the initial break in.
If you are not familiar with the S7, it is basically a WS7 with cheaper bearings, and a non coated crank. It also has an 8mm carb Vs. the 9mm on the WS7 (The WS7 comes with an 8mm restrictor). It uses the same piston, sleeve and rod out of the WS7, and gives about equal performance to a WS7. S7s have an extremly smooth powerband, and huge top end.
Obviously this engine has tons of compression, and plenty of life left.
It has never seen temps over 200.
It has never been in dirt, and has only been run with a clean air filter.
The engine has an extra .1mm head shim for 30%.
Original RB #6 standard plug included.
This engine uses standard plugs, and has an 8mm carb that is ready to accept RB carb restrictors. I have another S7 in my car, and have owned many in the past. I generally run a 7mm restrictor, 9886 or 2035 pipe and McCoy MC-8 plugs. I also run hard alumnium clutch shoes and 1.1 clutch springs with this engine.
A JP-3 or 4 would be very good for creating smooth power with this engine, and a JP-1 would provide a ton of bottom end power.
$190 shipped OBO, no low ballers. These go for $260 new.
