Thanks, we welded up a custom sub-frame to keep the 20b at the same height as the 13b

Here is a video of the first test drive. What do you think? I have to fix a little exhaust leak on the manifold. Other than that, I thought it was pretty successful.

I just added the Shine Auto Project Low profile spoiler. I think it looks pretty good.

We are just finishing up a few clean up items, then it is off to the dyno for tuning!

Did you have to make a custom oil pan to lower the engine? How is the bump steer using that subframe? I currently have the Pettit / Hinson type.

They way we approached this was to make the sub-frame wide enough to allow the stock oil pan to drop down. These pics are the best I have to illustrate what we did. Bump steer was not really an issue due to keeping everything pretty close to the stock geometry. I think we needed a longer bump steer length (not much at all). Hope that helps.

Thanks David, however we have to really give thanks to Rohan of Rohtech Motorsports as he is the actual builder/fabricator of the project. I was just more of a "consultant" of the engine build because I had to go up South Carolina on business during the majority of the build. I did make it there for the dyno tune basically monitoring the critical engine paramaters as Rohan tuned it. It made the 521rwhp at 15psi so we belive the motor will be pretty safe.

I just got the Seibon ST hood today. We installed it on the car and I think it looks pretty good. I warmed the engine up and the hood remained cool, but you could really feel the heat coming out from the vent/louvers!

Here is a walk around video of the completed engine swap. I think that transformation has been well worth the wait. The power is ridiculous. Thanks to Rohan at Rotech Motorsports in Winter Garden, FL!
