There is so much about porting here and most people send there stuff off to brand names(shops) to get checked and ported.

well this weekend at the tunning meet several guys have bought so called ported and blue printed motors only to have them brake. One had a motor sent back three times. Now I will say I have seen the photos and have been on hand at another shop where the owners or the shop decide to say **** it and take the motor apart.

I was floored to see the bullshit porting. Side housing with runs on the surface from the die grinder, ports that are so big there is no way the motor can stay together( seals cannot pass with out dropping) , . An intermediate housing that is what we call an abortion motor is welded on with out the buyer aware of it.

So I ask you members..... should I try to get these photos and post for all to read and then let the individual builder explain? Why should these cats keep taking your money and producing crap with no consequences. It my understanding that these guys will not make good on these motors . I may see if the owners dont mind but you know how it goes.

Oh.....dont throw in bad tunning cause fucked up welded housing and un measuerd porting the picks blows that **** up.

If the admin says no way then thats cool.

imo those photos will be very helpful for the members who does not do their own engine rebuilds.

Show it! Mazda, RX-7, and the rotary gets the bad rap when these "builders" massacre these engines. these guys with these hacked engines then go to the strip and destroy them (If they make it there) and make us all look bad.

OK,OK,Ok....... heads up! These were emailed to me just now from the shop owner whom I emailed this thread to. This is the 1st guy/shop. I will submit the names after I get some feed back.The other engine is from a VERY common shop here on this site so I will get these from the New Orleans owner as soon as I can.

They were the one's with welded housings.

And my own nonbiased opinion...non of these cats have ever done work for me or my friends.The first guy I dont know but I have seen his name on RX7 Club.



[SIZE=14]REMEMBER THIS IS A FRESH REBUILD WITH ZERO TIME BEFORE BRAKING[SIZE=14] This is what they got in the second or third rework.

next...

rotor

seal damage

IF I get the next set from a totally different owner and the guys he sent his too, they are much more dramatic! I mean they lowered the port bottoms , raised the top and nonwere the same size. Timimng is way different , blowby on the rotorts etc.......this is what you pay good money for.
