Hey Dusty just a follow up on this thread. Have you decided on a turbo for your kit yet? It seems that Safari used an T4/T3 hybrid simillar to what you mentioned earlier.
 
You are quickly becoming my hero. . .but that manifold is for a supra?
 
Ok
all the parts are ordered and few parts are coming in:
turbo
intercooler
wastegate
gaskets
v-band flange and clamp
lots of silicone couplers and clamps
stainless lines and fittings to an from the turbo
miles of aluminized mandrel bends in many sizes
weld els (supra manifold far too short to modify)
a/f ratio gauge
boost gauge
welding bungs
turbo and wastegate flanges and gaskets
vacume lines
Im hoping to start this weekend and do a marathon build:

A few issues still bother me. I ordered a big K&N cone filter as I think the oe filter box just is going to get too much in the way and will get too hot. The MAF meter will need to be relocated which will entail lengthening the wires to it by saudering in longer ones. Will lengthening the wires affect how the MAF meter reads?

Next. I have worked out the down pipe from the turbo which uses a vband clamp and have adapters to take the 4 inch turbo exhaust down to the 2'' oe exhaust. I have a new weld in o2 sensor bong and plan on completely removing the 1st CAT but leaving the second. Assuming I a know shady california state employee who will let the cruiser pass inspection with illegal mods, will it pass smog with only 1 Cat?

Next. I wasnt planning on using a fancy stainless flex joint from the downpipe to the rest of exhaust but instead using just a simple exhaust joint (smaller pipe into bigger pipe) Does the safari system use a stainless joint?

Next. how have people plumbed in the Rising boost rate fuel pressure regulators? the inport scene can purchase cheap regulators that screw right in the fuel rail in place of the oe regulator

Ill neede to have a custom ac line made to go from the firewall to the compressor as the oe pipe is in the way

I need to run an oil return from the turbo so Im going to need to tap the upper oil pan with either 1/2 npt or 3/8 npt (ive got the fittings to do either) I know safari does this upper pan tap and I know where they tap it-i've read that the pan is then so Im a little worried I wont be able to make a good thread. Does the lower oil pan completely fill with oil? I immagine it does and this is why the return cant go there. If I cant seat a good thread with the tap i have purchased some weld on bungs (3/8 or 1/2 npt) so I can weld to the pan. But then I will need to remove the upper pan. Can I remove the upper pan with the lower still attached? If I really wanted to take short cuts do you think the motor would catch fire if I welded the bung to the pan with it still on the motor? (just kidding) I know the import boys use JB weld but I feel uneasy about this.

Lastly I am a little worried about how I will bolting my home made turbo manifold to the oe manifold. I orderd new gaskets and bolts from dan for the connection. The gasket between the oe exhaust manifolds (remember there are 2) are these metal (i hope they are stainless) donut things about 1/8 inch thick by 1/8 inch deep. (looks like a big wedding ring) I hope they hold up to the heat. I also purchased the gasket and bolts securing the oe manifold to the head in case I have to abondon my sub manifold idea in place of building an entire new log manifold . I have also considered welding my sub manifold directly to the oe manifolds-that is certainly a commitment. Anyone have an OE manifold for cheap? this would make welding mine easier.
