Anybody know about porting? How much does it generally cost to have the inlet man and head ported in ma70 turbo? Is it worth doing while the head gasket is off?

Also, in the nissan RB engines: they perform better with the NA cams fitted to the turbo models. More lift and duration i believe. Is this the same with the ma70?

If the MA70 is an imported '89 S spec manual what diff will the car have and will it be up to the job?

What ecu should i go with if i decide to go aftermarket(living in adelaide)?

Also, what injectors should i buy if i upgrade them? Are any other cars injectors a drop in fit?

In my opinion even for high hp applications a port job is not really that important.. I would get the inlet manifold port matched to the head however.

As for the cams if it is one of the 89 S spec or GRP A cars (The one with the extra big vent at the front) Then it already has uprated cams. If not then the N/A cams will probably be an improvement. Im not 100% if the NA cams are the same fit however as the NA motor runs a dizzy of one of the cams.

As for the LSD it has a torsen centre factory so it should be fine...

As for the after market fuel computers a like the Haltechs the E6X or E11s are nice ecu's.. If your on a budget ive seen a megasquirted 7mgtes at about the 400hp mark

The car uses top feed injectors and most top feed injectors will bolt straight on.. any aftermarket injectyors for GTR's should be fine, however the stock 440cc should see you upto the 300kw mark anyway.
