John Welch T04E Stage4 upgrade (notes)

This will give Garry K a basis to build a 910 for me:

Engine spec:
1-2 mm over size intale valves
104 intake cam moved 4 degrees
370ccpm mains 440ccpm secondarys
43 psi rail pressure
Open exhaust
Electronic stand alone boost controller (no fuzzy logic BS)
Good compression numbers..

Turbo: Garret T04E

T-3 turbine housing with a special internal wastegate setup that has a 3" v-band discharge. Compressor side has a 3" inlet and the normal 2.35 outlet to go to the charge cooler. Still uses a ceramic BB centersection. There is a bit of lag over some smaller turbos, but still less than the stock Sport 300. Highest we have tuned to so far is 441hp at the wheels.

I've also got a 3" down pipe for it, you can use as the start of an exhaust system, or if you have left hand exit, we have a one piece pipe with an additional o2 bung for a wide-band sensor.

I have several of the turbos from the original X180r's and what bothers me is how small they are. People claim that they were making 400-500hp on these engines, but the turbos are smaller that what I sell people for use on their street cars.

We can supply mem-cals or EPROM's with code if your's already have a socket.
