Port sleeve mod?
I know that pinnapple racing sells the flow-friendly 5th and 6th port sleeves, but my question is, how hot do these get? Would it be absolutely insane to consider making your own version using the old sleeves and some sort of filler-- say, JB-Weld? What is the most heat-resistant filler out there?
Anyways, I took my intake off because of some vacuum leak I can not find, and I decided to make my 5/6 ports work. I took the sleeves out and they were really dirty the ports are bad too (still spun tho). There is a lot of carbon build-up in all of the ports. I could hardly believe that the poor car was running at all!
Anyways, I broke my oil injector vacuum spider (and I was REALLY careful). And I also tore two of the oil lines off of their injectors...
What's the best way to fix this?
Also, what is this item?
I think this may be where my vacuum leak is.
I think I am gonna proceed with some mild porting, and maybe try to get a hold of some TII secondary injectors. Does anyone have any for sale?

New line from the factory. Ask ROY_JAMES how well his JB weld sleeves worked. It cost him an engine. You do not need larger secondary injectors until you dyno out >200hp

mazdatrix sells new lines. $20 a peice.
The thing you think is causing your exhaust leak is the EGR. Ditch it. The S5's (or mine at least) didn't even have it.

I've run plastic steel epoxy in my 6 port sleeves for several years with no problems whatsoever. My '88 had it for a few years and my GSL-SE currently has the epoxy in them. The glue should work fine if you cleaned everything first. I have plastic steel epoxy in my port runners on my turbo 4 port to help smoothen then out. No problems there either. $60 for Pineapples sleeves is too much when you can spend $5 on epoxy and do it with the same results.
