Funny, I thought Paul knew every little trick in the book to increase horsepower.
I'll post an excerpt from the e-bay add since I can't post a link to it:
"This is an inexpensive and simple way to add power to your Suzuki G13A and G13B motors!
This is an oil- or crank-scraper for the various SOHC and DOHC 1298cc and 1324cc G13 engines used in many Geo and Suzuki models (there is a very slight difference in stroke between these two displacement engines which amounts to a net difference of only .75mm or about .030” at the scraper and this is allowed for in the design). The scraper is constructed from 12 gauge mild steel (approximately .10” or 2.5mm thick). Installation instructions are included. Some minor clearancing might be required.
The scraper includes a set of 5 longer main bearing cap bolts which allows it to act both as an oil scavenger and a light duty main bearing girdle. The existing main bearing girdle as used on the G13B is retained but is not required to fit the scraper (some of these engines do not use a main bearing girdle as seen on the G13B). A picture of the installed oil scraper is shown.
Many sincere thanks to Suzuki enthusiasts David Gray and John Strattons without whose help this scraper would not be available!
As the engine rotates, engine oil is not thrown off but instead sucked into a tornadic windage cloud around the crank and rods: the horsepower that is required to move and move through that oil is significant. The scraper strips away that cloud by coming close to – but not touching – the spinning crank and connecting rods and this frees up that internally consumed horsepower. Remember that as you accelerate, brake, go up and down hills, and turn your vehicle even more oil is whipped up and power lost; stock engine output is determined from a static test so the scraper will help restore that lost power ASAP! In highly tuned engines, too much oil splashed on the cylinder walls can overwhelm the piston rings and thereby be introduced to the air/fuel charge. This contamination will lower the effective octane rating of the fuel and can lead to detonation. This is well-proven technology that has been used with great success in small and large displacement high-performance street and racing engines for decades. In fact, we just completed an updated scraper design for a 1965 Pontiac 389 -- this is an OEM engine that utilized a crank scraper in the form of louvers cut into the side of its windage tray -- that's 38 years ago folks.
You can find more information on crank-scrapers if you follow the link found in the “ME” eBay icon.
Each scraper is made to order so please allow ten business days for fabrication from the date that payment is received. That being said, we now have a CNC cutter which has allowed us to ship most orders within a day or two. "
