Hey guys...I just purchased a 87 turbo II and the apex seals are gone on the second rotor. If Im mechanically incline...on a scale of 1-10, 10 the hardest, how would you scale rebuilding a 13b?

Also...what specialty tools will I need. If its too hard, where can I get a good priced rebuild?


I know...I know, new guy and already asking a bunch of questions... Thanks!

 

Get this video Overhauling the 13B Rotary and make the decsion yourself. They seem to be easy enough but you have to have an attention to detail and be prepared to buy a few parts.

 

Any idea as to how much...average I might be spending? I was searching around on this site and seen all sorts of numbers. Rebult kit (850.00)...I want to make sure this will last awhile and give me the ability to put more boost than stock.

 

And then there is the - Oops the rotor housing got gouged by the broken seal.

 

...and for that matter the turbo as well.

On a scale of 1-10, the build itself is about a 4. However, the cleaning, measuring, clearancing bump the whole project up to an 8 or so. There are a number of little "gotcha!" type things that can easily result in a 1000 mile engine. Seen it before. I would suggest you farm out the work to a competant rotary shop until you have more experience. Or take the risk and buy a cheap J-spec engine.

Generally with rebuilds, the words "cheap" and "good" should not be used in the same sentence, unless you are saying "cheap rebuilds aren't very good".

 

Ok...you got me on the cheap thing. I imagine with the "gotcha" things, a large part has to do with scaring and mis calc when measuring wear? I want to do the 3mm apex seals and purhaps the street porting. If I have rebuilt other motors...you think I have a better chance at something more than a 1k motor?

 

honestly there two routes I would recommend, one getting a used Jspec motor, I got mine with tranny shipped to my door step, or two getting someone else to help you do it that has done it before. Like Aaron said, the rotary has a lot of things that is picky about, and for a good rebuild kit, spend the money it's well worth to go the extra mile for these engines...

 

oh yeah, I paid 850 for the engine, tranny, and all of the engine accessories(sp)... for you it would be a drop in, and you would have an extra tranny, my engine only came with about 35-40,000 miles too

 

Wow! Thats not bad. If I did that...at least I would have the car on the road...then I could rebuild the other. Where did you get your motor?
