A friend brought his motor to me after buying it and installing it in his car. It was smoking like a SOB. He said the guy just rebuilt it and only had about 500 miles on it.

Well we pulled it apart to find the problem, I started to laught we i pulled the rear plate off.










This guy needed to drop the die grinder when he had the chance.

 

OMG what for a idiot lol

 

Wow... You know, I really don't know much of anything about Porting but...wow... That looks....really bad...

 

Yikes...Whoever ported that engine nearly broke every rule. Never port towards the interior, never port past the side seal track, don't let your grinding stone skip accross the sealing surface of the iron...

 

Im glad I had my motor built and ported by Kevin Landers which might not be the most superior porting out there but I know he does respectable work.

Im not even sure if Landers porting is a mild port or extended port.

 

yeah, I'm the guy who bought that screwed up motor, here is the thread that I made right after I opend it b/c I had no idea why it smoked sooo much. https://www.rx7club.com/2nd-generation-specific-1986-1992-17/porting-question-ports-too-big-%2A%2Apics%2A%2A-497180/

 

Kevin keeps the porting on the safe side unless you ask for extended porting. I think he uses a pineapple template too.

 

I asked him about his porting before and he told me he makes it go as close to the waterjacket and if it were any bigger would be hitting it, so I figured he uses the extended port on his porting but the again maybe it is a mild port. I dont know, maybe he can come in here and clear it up to me ?

I doubt he remembers me , but I actually met him in person to drop off my motor.

 

Damn Who did that ???? WOW

 

that's one problem i have with the forum, it gives people the impression that **** is easy to do, this is a perfect example of NOT what to do.

 

+1 on the who dunnit

 

With how bad of a job this guy did in everyones opinion on here , you would think this was probably the guys first attempt at trying to build and port a rotary engine because he's made so many mistakes its hard to believe he's built one before if hes done such a lousy job at building this one making everything f'ed up, because we all know how crappy of a job he did on this anyone that he offers to build/port another rotary engine will laugh in his face, problem is no one knows who he is so he may still be making crappy builds for more people which isnt good for us rotary owners.

I want to learn to build and port myself, but I'm pretty sure its something you master over time and learn from your mistakes. So if this guy knows how bad he did I hope hes smart enough not to make the same ones the next time, but then again some people think they are right about everything when it comes to their style of building.

 

+2, that's worst than my first time porting. wow

 

Sorry, but holy run-on-sentence Batman!

And I'm no engine builder by any means, but that looks like absolute doodoo butter.

I don't think common sense ever played a role in this port job.

 

common sense.. definitely not. if he had posted pics of these ports before assembling the engine he would have gotten a definite thumbs down and people would have told him not to waste the money on parts in putting that engine together.

even my first attempt at porting a rotary came out 1000 times better than this, this person obviously didn't use a template either nor followed any of the basic rules for porting rotaries, instead he just thought "bigger is better, right?".

talk about a dumbshit move...

 

I think the guy that ported that motor had a few too many Beers that night...lol... he mastered the art of Drunkin Porting.....lol

 

Holy run-on-sentence Batman

 

i like how they made these giant wide ports, and didnt port for timing at all.. the one direction its safe to cut in, that produces the biggest gains, is where they didnt cut.

 

Yep, this was done by a porting GENIOUS.

 

you misspelled genius, lol

 

wow, I feel like an idoit

 

Don't worry, you're not as dumb as the guy that did that porting.

 

I normally make at least one spelling error per post, but I always re-read my posts and edit them for mistakes. Apparently I didn't do it this time.

 

guys, since we're on the topic, what about my porting??
