Dude, you are a champ. If you get a chance, could you email me a Screen shot of your timing Table? Also, What would you recommend is the key to the hidden power of turbocharged engines ?

This is the most awesome build in the history of the internets!!!

MAD02: thanks!

fifty: Well I dont have the ecu map here but ign is something like 26 on 1.5bar and 22 on 2bar on high rpms lower around max torque area (for this camshaft) The ignition table is so individual you cant use then between cars with different heads and camshafts etc. But mail me you're spec and then i can help you with one for you're concept.

The trick is to understand these M10 heads, they are ok standard but very hard to make real good (look at my head for example). One important thing is to make the engine breathe, right dimensions on the turbo manifold, downpipe (you need bigger than you think) and turbo. Most ppl are afraid to use truck turbos "because they look so big" and think they wont get any boost before the revlimiter. Thats all wrong. The register will be real good if you use all the right parts from a to z on the project.

So my engine is a

2L 8.5:1 compression.

Forged pistons

head is a 1.8I head with +1mm stainless exhaust valves.

the camshaft is a 290 degree schirck copy with either 9.5mm or 10.0mm of lift.

the head has been ported and polished very efficiently.

tubular exhaust header, with a 38mm tial external wastegate.

turbo is a .63 AR 50 Trim.

Im soon going to be hunting a new turbocharger. such as an HX30 or HX35 sized holset

i didnt catch your email address so I just typed it our here lol.

Whats the Inducer and exducer in mm of you're turbo compressor and turbine wheel?

[fiftytakedowns]

Im actually in the market for a different turbo, all I ahve is an off brand ebay turbo to get the car goin. What size would you recommend?

my back up turbo's oil seal broke so it needs to be rebuilt or sold.

it was a .42 ar 40 trim.
