From ATS’s website:
There is no replacement for displacement. By adding approximately 10% more displacement to the original MR2 engine customers are finding much quicker turbo spool up, better driveability, wider torque curves, and excellent low rpm response. The ATS 2.2 stroker short block is built from a 3SGTE block so there is no additional fabrication required for installation. All accessories, oil and water lines bolt up just like factory. Each 2.2 stroker short block includes:
- 3SGTE cylinder block – bored .020″ over, checked, decked as necessary
- 5SFE crankshaft – machined to accept 3SGTE connecting rods.
- Correct rear main seal
- Reconditioned 3SGTE rods
- ATS Forged Pistons (built for us by Wiseco) .020″ over bore pistons with file-to-fit rings
- ACL standard engine bearings
- Balanced rotating assembly
- Hand assembled by ATS Racing, the world’s most experienced 3SGTE engine builder
I do not know the exact build on this short block as it came with a car I purchased. The engine was removed to go 2GR. I have already sold the cylinder head and only have whats shown. No oil pan, etc.
