Anyone interested in intake porting templates? I just got the first test sample back from CNC laser cutting and it looks fantastic. We will be doing them in stainless steel and the port shapes will be pre-cut; not just scribed, like other porting templates.

The test piece is for a 13B-REW, but I already did streetport template drawings for 13B-T and 13B-6PI, so we can get them made quickly. Soon, I will also make some exhaust porting templates.

Price for the streetport intake templates will probably be about $35. The exhaust porting templates will be more like $20.

 

I would really like a set of 13B-6PI (GSL-SE). It would be awesome to have them pre-cut. How long do you think the turn around would be for getting some of these made?

PS: Great job on the engine building thread. Lots of very good info. I will be putting much of that info to good use in a couple weeks.

 

sounds good! I'd be interested in the streetport intake and an exhaust porting template aswell.

 

I want the 13B-REW intake port templates.

 

interested in the exhaust template. do you have any comparison pics?

 

how hard is it to port out the intake and exaust ports? any plans for race port templates?

 

Well, that's a tough question to answer. With the right tools and some basic know-how, it's not difficult at all; just time consuming. The tools required are a die grinder (air, preferably), an assortment of Carbide bits, cartridge roll sandpaper, etc. The know-how is the big variable. In the next issue of MazdaSport Magazine will be the first of two articles I wrote on Porting. The first is more theoretical/analytical while the next one will be more a hands-on demonstration. Neither will be enough to do more than scratch the surface, but it should be a good introduction to what is involved.

We are actually thinking about doing some instructional videos in the near future, so stay tuned.

 

ive done porting on v-8 cylender heads using the same tools: carbide bits, and sandpaper bits, simmilar process? im in corvallis and am up in the portland area ocasionly, could i stop by and check the shop out sometime, and possibly even watch one of you guys do a port job? i beleive you build the streetport in the car i own now, i bought it from chuck (pdxrx7) red 93 touring. anywho, let me know, thanks

 

I would definetly buy a video.

 

^^ lol wtf

 

Id buy templets for a rew

 

Do you have sample pics of the templates?

 

i would be intrested in brige port templests for a 13b N/A intake and exhaust

 

count me for the 13B-6PI templates now aswell.

 

I will be finishing up the CAD files on these this week and should have them laser-cut in a week or two. I have been really busy lately, so there's been no time to get it going earlier.

 

no problem from me

 

let me know when there ready

 

Hi Blake and all the others,
do you have also some of these templates for 12A engines.
I planned to rebuild a 12A NA engine for the next racing season.
I think about big exhaust ports and eventually bridge ported intake.

 

any word?

 

I've been really busy working on an Engine Rebuilding Parts Selection Guide and getting ready to go to both Sevenstock and the SEMA Show next week. I still have not sent the finalized CAD drawings to the CNC Laser Cutting place. Sorry.

Please note: I did a little house cleaning in this thread to get rid of the funny but irrelevant references to a fictional "Wu Port". You can imagine the confusion that could cause someone who is not very familiar with rotary engines! Sorry, but I want to keep threads like this on-topic and uncluttered. Thank you.

 

I am interested in a set for intake and exhaust.

 

BUMP!

 

I would like a set if you do the 12A?

 

13B-6PI templates and exhaust template for me...

Do you have any port timing numbers?
