Hi,

Now that my Astra's S/C project is nearing completion (need a full 2.5" exhaust system): i want more !!

With this experience, and after having read many threads from z22se.co.uk guys, (vocky, evocarlos,...) i plan to rebuild an used engine lying aroung my garage.
The project is to make a +300hp engine.
Next, the engine will be put in a VX220.
I think the project will take me almost 2 years : time to do the job but especially the money come gradually.

Here is the list of changes I plan for this project:

_ Oversized Wiseco forged pistons 8.9 CR
_ Eagle conrods
_ Cylinders reboring
_ Ferrea +1mm Exhaust vales
_ B207 Cylinder Head
_ Porting and Polishing exhausts ports
_ Lightened flywheel
_ Balancing shafts removed
_ Uprated Clutch
_ Injectors (VXR or Bosch 650cc)
_ Harrop SC
_ 2.9" S/C Pulley
_ Phenolic gasket
_ LS4 T/B
_ 4 in 1 Exhaust manifold
_ Full exhaust system 3" with catalyst Sport 200cpi
_ ECU Remap (Obdtuner)
_ Purchase of the Speedster
_ Swap engine and burn asphalt !

A lot of work so that's why I plan a very wide timing!

Here we go, we are still in winter so no motorcycle or too many cab trips. That will leave me time to fully disassemble the engine lying around in my garage to bring it literally and begin preparation.

Here the 82.000 miles engine:

Tony, don't know yet but surely keep the OM water pump, going to electric add more cost for little hp gain. Don't change the cams for comp cams stage 2 for same reason !

it is a standard z20let clutch the luk number links to 93180360
the z22se and the z20let clutch will both do around 280-300hp but they recommend a better clutch above 270hp the gm one slips after a while
