2.7 liter QR build..
 
http://www.fi-r.net/images2/QRbuild/RyanQRbuild1.jpg

Here, I will share details/pics about a customer's 2.7 liter (sleeved/big bore) QR low compression engine (for turbo).

Today, we mic'd the mains, and installed the crank/girdle with AEBS main studs. All clearances came out fine.. coming out in the range of .0007" to .0010". This is perfect for a engine of this caliber, with aluminum bearings.

Yes, it is a stock crank..

We have sleeved the block, using aftermarket iron sleeves.. closing the deck, and solidifying the block for big horsepower levels. With the new sleeves, we can go much larger on the bore.. giving us the bump in displacement that we were looking for, while still maintaining cylinder wall integrity.

We offer engine parts, as well as fully built crate engines.. ranging from mild to wild.. depending on your budget/goals. Please email me for more details.. [email protected]

Should last years.. if it's tuned properly and taken care of. Email us with what you're looking for, and I can put together a package that suits your needs. [email protected]
