Want to add some CFMs to your motor ? It's generally accepted for most cars that a CFM increase of 10% will result in a gain of between 5 and 15 HP. Results will vary for each car and combo but one constant is that the improved throttle response will increase your grin factor by 100%
On those throttle bodys having shaft seals, new replacements will often cure drivability problems. plus, by curing boost leaks at the shaft, a significant improvement in turbo efficiency can result in a gain of 10 HP or more.
A bored throttle body is a simple install. Usually 30 minutes or less. most cars sensors reset automatically so you may not even need a scan tool for the installation. To get the full benefit of the new TB you may need to port the intake to match but an injector upgrade won't be needed. Your cars MAF sensor will compensate for the additional CFMs from the larger bore throttle body.

My Ebay Feedback HERE
Besides my interests in Turbo Buicks I also designed the simple, reliable and inexpensive DIY ALKY INJECTION SYSTEM The DIY Alky Kit is the forerunner of many of the current alcohol injection systems being marketed today.
When I retired from my USAF machinist job I decided to expand my hobby of machining throttle bodys for Buick GNs to include other car makes. So, with close to 50 years of machining background and 18 years experience machining & rebuilding throttle bodys, I believe I'm able to offer the experience and skill required for your throttle body service.
