im thinking of turboing a vx hatch but i have a few questions first?... what kind of fuel management is offered for this motor? will crome or uberdata work with this ecu??? ive herd bad and good things about the d15z1 but i think it will be a fun little project. ive searched but cany find much on turboing these engines??? does anyone have sucess with these. pics would be great!!!

-thanks

maybe thats because you dont have a good tune.

to the OP:
search around the FI forum and maybe talk to Bense, he pretty much wrote the book on vtec-e performance .

schardbody knows a lot about turboing a bone stock d15z1

this is very true but it is getting built as soon as i blow it up, but with a tune now it would be able to keep up with stock gsr's and civic si's

Probably beat them unless you suck at driving. Boost the hell out of it.

True, take care of that matter and you are good to go.

Get an EX/SI transmission.

Get a stand alone like the EMS, new tranny, and keep the boost around 6-7 psi to be safe. I'm not sure about those injectors either. I know on the 96+ Civics, the non-VTEC injectors (and the Y5 injectors) are smaller.

How can you say that when you don't know what turbo he is running?

Boost means nothing, its how much power the motor can handle

i have slightly bigger injectors and its quick the trans is rough in high rpm but it still can keep up with the grs's and si's when it doesnt lag, with the setup i have and i have been running 9 psi all day for 5000 miles with no problems
