Engine Build and Turbo Motor Cycle Modification Style

With the motor sorted out, it was time to match a new turbo kit with the performance capability of the XR-1.7. Cue in Boost Logic’s SC 61 turbo kit. Boost Logic is new to the Evolution world, but have a big reputation for making gobs of power in the Supra market. Their SC 61 turbo kit shows right away the proof in the power making pudding, especially with features that compare to what the more expensive kits have for less money. Features include:

• Ceramic Heat Coated SS304 Tubular Manifold w/ true merge collector(1/2" Thick flanges)
• Tial 44mm Wastegate
• SS304 Dump Tube
• PTE SC50 T04E DBB Turbo w/ vband outlet
• Boost Logic Water Line Kit(assembled with Aeroquip pushlock fittings)
• 3" SS304 Vband Downpipe
• 3" SS304 Vband Midpipe w/ flex joint(Bolts to stock catalytic converter)
• 3" Aluminum Intake Pipe 3" K&N Filter
• 2.5" Mandrel Bent Aluminum Intercooler Pipe
• 3 Ply Silicone Hoses and SS Hose Clamps
• Boost Logic Oil Feed and Return Kit(Assembled with high quality SS line and AN fittings)
• All nuts and bolts needed for installation
• 10" High Flow Fan

Installation of the entire setup was complex and will require professional help. With our lack of wrenching skills we opted to go with pros to get everything installed correctly. Atlantic Motorsports was the shop we went with to get the final installation done. Being a MIVEC conversion, we had to grab a spare Evolution 9 main harness (engine harness) in order to get it all plugged up with our AEM EMS (we had to purchase a new unit to control MIVEC). The conversion isn’t rocket science but does require a large portion of time to make sure all the details are taken care of.

With the basic installation out of the way, the proper motor break-in procedure needed to be performed: 2 heat cycles, then an oil change, then a low boost break-in, 200 miles of driving, and finally another oil change. Atlantic Motorsports then put their focus on tuning the beast. With a few clicks on the laptop and a ton of dyno pulls, the car was ready for action. Final Power Output: 498 whp & 399.3 ft-lb @ 23psi.
