How much is my ported motor worth?

Im very new to the rotary scene. I got 1990 rx7 that is n/a and has a dyno sheet for the car making 220 to the wheels.
the guy ported the motor. he said he port matched the intake ? and that it would be considered a nasty street port ? im wondering the general price range if i was to take the motor and tranny set up out and sell it how much i could maybe get for it.
anything is appreciated.

Can you post that dyno chart? Have never seen a 6 port make that power and post a chart. Be nice to actually see it. Anyway, depends on what it is being sold with. Come with a standalone computer? A stock ecu? What kind of tranny? If its a stock ecu, and non turbo trans with a "220" wheel engine.... I would say its worth $2,000-2,500 in todays market

just putting this out there, too ...

i can't (and won't) comment on an actual number, but price probably also hinge upon the motor's history (who built it, when it was built, etc.). so if you decide to sell, you may want to have that info handy.

depends who built it, and by that I mean what parts were re used and what parts are new.

I built a ported engine for 300 dollars before, doesn't mean its worth squat because its mostly used parts.

thats the set up. the guy ports everything from dirtbikes to jetskis. and got the car and ported it then got it dynoed.

but its a non turbo tranny and stock ecu. whats the difference between the turbo tranny and non turbo ? just different gearing?

not just ... it's a completely different unit - construction-wise. generally speaking, the Turbo trannies are much more robust in construction. obviously, they are built to tolerate more torque than the non-turbo units.

I just hate the weight increase with the turbo trans upgrade.


The transmission isn't going to affect your power output on the dyno if that was what you were asking.
