How are you going to run the oil drainback line from the turbo to the sump?

The turbo sits over the breather and it looks like everyone just feeds into that.

Since we're talking about boost, we should probably talk about lag too.....

I picked a smallish turbo to minimize lag.  In fact this gt1549 turbo has a few different wheel trims that are more suitable for small bore engines. I took that same platform and went with the biggest wheels available for that size turbo that are better paired for a large bore.  You don't want a turbo capable of 250hp when you are shooting for 120hp.  Another thing I'll be doing is injecting my water/meth combo directly into the turbo compressor.  This effectively changes the turbo map creating a more efficient output due to the reduction in compressed heat.  You can run a smaller turbo but more boost this way that would normally stop producing power at the same boost levels.  As well as it eliminates detonation should you accidentally run lean.

Just stumbled onto this site. They have some cool stuff like how to convert a A engine to 5 groove serpentine belt. They also some nice bits for supercharging or turbo. Plate for raising thermostat housing so can use a GM temp sender in the gap. The easiest way to see what they have is click on the Purchase tab. Pic shows temp sender and serp. belt.

Putting the mini to work today.  Have this 998 auto I needed pulled into the shop to haul up to Dave.

Someone was asking about auto shift cables...

If that's going in the Pup, won't he need the subframe too? In fact, he'll need a two bolt automatic subby, right?

Are you going to build the subframe up for him? Disc brakes and such?

That auto shifter looks the same as the one I dug out of a box o' junk maybe I will hold onto it in case someone needs one some day. Thanks for the pic.

Yeah I'm building subframes for him.  But this auto subframe is a 1 bolt so I have to fabricate a little on the pickup bulkhead to support it.

Gave the car a wash today and got the new 59D timing locked and setup with the black box and verified with timing gun.  Took it for a spirited drive.  After driving the bus for the past week the mini felt like a formula car.
