Ive made a few mods to my zed now, T28 turbos, induction, front mount, bigger rad, de-cat etc, she still runs without missing a beat (although over fueling a little) but im not getting the full use out of it all as i havent done anything with ecu, do i need a chip, ecu, piggy back ecu, boost controller or something else? i want to start upping the boost a little (its still at factory 9psi). can anybody tell me what i need and where i can get it? also whats the most psi i can run safely without blowing internals? ant help would be appreciated.

Yes you need a remap. The cheapest, and best solution for you setup would be a remapped stock ECU. John Dixon and AndyP are the two most popular choices.

 

You will then either need a Boost controller (highly recomended), or stick in some boost jets.

 

Your limitation is the stock injectors, and with them your looking at going no higher than 15psi, despite the T28's and fmic

cheers, how can i get either of their numbers? could you email them to me at l444sty@hotmail.co.uk if you would rather not post them up here, thanks

Best way to contact them is by PM. But you need to be a subscribed member (£20 and well worth it). Details here : http://www.300zx.co.uk/forums/showthread.php?t=70720

Alternatively you could put up a FAO "John Dixon/AndyP" thread.
