Turbocharging Z22SE with Z20NET turbo

#1
Hi all. I've got an Astra mk4 with a Z22SE engine I'm going to turbocharge. I've bought a Z20NET manifold and turbo and am hoping to get a Z20NET sump and oil feed lines soon. I'm also saving for piston rings, forged pistons, con rods and reinforced bearings from Dbilas. Not currently sure about an intercooler, was wondering if a NET one would fit in front of the Astra mk4's radiator? Not sure what I'm doing ECU wise yet either...:facepalm:

Anyone on here done this exact conversion? Seen a few posts on here but wasn't exactly clear on whether or not I'd HAVE to bash my bulkhead back, remove my A/C, etc. I'm a complete novice with decent but fairly basic mechanical knowledge and no real tuning knowledge. Thanks in advance.(y)

ive done it ,, the problem is the ecu,, but there is a smart man from Holland who can use your 2.2 ecu , and let it run your turbo charged engine , and yes you have to get the hammer on the bulkhead,,

for engine internal parts you may be better off getting parts from the likes of ZZP or Real Street Performance in USA. better parts at lower prices ;)
Keep us updated with the build.
Dave Gillbert has also done a z22net in the Vectra C

Yeah, I'd like to keep my standard ECU just the sake of simplicity and everything else on the car working. Okay, the A/C pipes be alright?

ZZP or Real Street Performance? I'll have a look into them (y)

I'll keep you posted when I get the build started, just gathering parts and planning at the minute haha (y)

Thanks for the replies guys (y)

Is the z22se ecu mappable to read boost. I heard on the grapevine that someone could download the vx220 turbo software on the Z22se ecu?

yes, there is a way with the software courtenay sport use and some other one i believe?
the mk4 astra could be run with a z20let ecu set up and z22yh crank on turbo i guess? or go standalone but you would still need to use a different crank pick up and ring as the z22se is a bit strange and most ecu's use 60-2 rings.
