honestly there isn't all that much work involved..
i wrote up a step by step guide years ago when i first did mine..
i did my entire conversion with a set of average tools.. like scredrivers.. socket set and spanners.. and an angle grinder.. the grinder is a must..
took about 2 days.. and i started with a front cut and my ae86 both with thier engines in them..
so really it's not that hard at all...
