yeah we can do that.... specifically waht would you want?? We'd tune it different for boost vs N/A. However a boost ECU will work on an NA car it just wont run 100%

thanks elwesso. I have the motor in a z32 but its in bad shape and weaker than my n.a z32. Im going to replace it with 94+ vh45 and a single turbo.I want a ecu that can support low boost and about 400whp nothing to wild.Reliability above all else. going to test it on my na vh first.

You need to get the motor running right. It probably has bad knock sensors or some other problem. VH45DE puts out almost 100 more HP than a VG30DE and weighs about 100lbs less!

no other problems beside overheated and bearing failure.but starts up first time and runs well.Im not going to use this motor for anything but a test bed for the turbo motor, everything will be made on the car as is and then Ill swap in a good vh. ps this motor sat in the car with no bonnet under a tree in NZ winter and was in bad shape to start with. cost of project $1325 Nz

are you running the automatic with it???

I can hook you up with a boost ECU, in fact, another one of my mates is going to have one made for his twin turbo VH45 5-speed in a Z32..... Right now using JWT boost ECU, going to have it redone by my ECU guy...

Im going to have to contact my guy about it.... I think shipping for our last ECU was about $30US, and IM not sure what we're going to be charging for ECUs this time around.
