that intake manifold wont fit your engine unless you have the supra tt engine already swapped in.
ebay turbo's arent really the best. the so called "gt70r" turbo looks like a copy of a garrett gt30r or 35r. the largest garrett offers looks to be a gt55r which is capable of 1600 hp, this 70r should as the name would imply, belong on a large piece of machinery.
