well when i bought my 87 TII it came with a second...rebuilt motor. id like to maybe get a little extra out of this motor after the first one dies and i have to put it in. PORTING? how hard is it to do and can i do it with my dremel? where do i get the diagrams for sizes... any help would be appreciated


heres a picture

there are easier ways to get power out of it besides opening your engine up and porting it.

 

If you have to ask those questions, then it's generally not recommended that you pull an engine apart and start porting it. However, if you insist...

Dremel tools work, but die grinders are far more suited to the task. I prefer grinding stones for the rough work, and then paper rolls for the finishing work. I personally use an electric die grinder. Air grinders are loud, painful to use and require the compressor to run all the time.

Mazdatrix, Racing Beat and most other vendors sell port templates.

 

if you never opened one before and this is a good motor to start with then dont bother. wait until you blow the one thats in there, why chance messing up a good running motor.

port the intake manifolds, turbo manifold<~~ gasket match them, weld a larger door for waistgate and port to match leaveing just enouph to seal and the TB. when u need to open the motor then port it out. just my $.02

 

thats what im thinking....doing my first rebuild, and porting the motor thats currently in my car. i would like to have the performance sooner but i would live without it. leave the running one in good running condition, and taking that chance on the one that i already blew up.

haha and aaron...you are probably right. i shouldnt be doing something like this but i love a challenge and i love to learn. why not jump right into it? its a good chance to learn more about these cars i have fallen in love with.

 

All things considered, I'd port it.

 

I'd port it too.
I tore apart a perfectly good motor to port it at a time when i really knew nothing of how the car worked. I looked at pictures on reted's site and basically searched... and i found enough info for me to decide what i wanted to do. The result was niiiiiiiiiiiiiiiiiice.
Oh, and I used a die grinder. My air compressor has a 60-gal tank attached to it, and if you have a regulator and you get the pressure up a lot higher than the operating pressure of the dremel, the compressor doesn't need to run too often

 

Pick up some old irons and housings to practice on if you're going to do it. Don't run the risk of killing good parts...Porting on a basic level is not really hard, and you will have good results. Making good ports means spending a lot of time smoothing EVERYTHING, keeping mindful of the transitions, and knowing when to stop. This comes from experience mostly.

 

well when i used to build motorized scooters i actually did some porting on a 46cc chainsaw. i know this is nothing like porting this car but i guess it is sorta the same idea. somehow...it actually worked.
