Mr Wingco57,
Have tread down this road myself an accurate renderings is a big, big undertaking.
I have a large quantity of data as was among those asked to "share" with HKM and that lead to the stalling out my project. I do not want to high jack your thread but wanted to share some pics of my efforts. First top pic is an OOB Tamiya, lower is the highly modified intake/exhaust.
