Swapmeet score

My friend bought this old R/C Porsche 917 for 8 euros, while I returned pretty much empty handed.

Engine Swap

Ragtops original engine is leaking so much oil, I need to swap it for my low mileage industrial engine. Question is, is it possible to mount the lower engine tin without removing the exhaust?

Original SprintStars

Since my chromed ET6 5,5" SprintStar Wheels didn't fit under TL wings even with 165 tyres, I managed to purchase not one, but two sets of ET26 5,5" Sprints! They fit like a glove with 195/60 tyre. I'll use 165R15 or 185/70R15 tyre at rear and 165/65 in front. The sandblasted set I'm planning on getting powder coated black and then painting on the silver highlights. Maybe fit them with studded tyres, so I can go slipping&sliding on winter time in SS Style!
