6 port end plates on a 13BT ??
I rebuilt an s4 13bt but over ported the endplates. I'm having trouble find a 4 port block for parts...Can I use the 6 port irons as replacements? Just the ends..the primaries are good... I already have a lower turbo intake mani modified for a 6 port block and I run an E6k so turning won't be a problem. Any modifications/problems i'd run into?

I'm sorry if it has already been done (send links please!), but i was wondering if a person couldn't plug the 5th and 6th ports with, say, a machined aluminium plug. Then when porting machine between the ports to make one big long single port. But only intaking from the 3rd and 4th ports.
Know what I mean?
Couldn't you then use the stock 4-port LIM?

^ That would probably work, but how effective could the porting be if it still have to breathe through the single port on the end housing?
And this is sort of a newbie question, but why aren't there more turbo 6-ports out there? Does it just not work well?

Where are the 6 port irons weaker? I am building a 6 port turbo motor but I won't be pushing that much power, just curious. I have already seen a few small cracks in my side housings around the egr passages near the bottom (heat not stress related). I'll get some pics.

350 at the wheels will most likely crack the rear one right at the rear dowel pin, just like it does to a lot of the S4 t2 engines. its a huge weak spot and mazda beefed it up more and more with each engine (FD and RE have some super thick casting there). j-rat just made a thread about cracking his rear iron, and karack also busted his. both had s4 tII engine. the 6 port iron's reinforcement is the most pathetic of them all. if it were me, and i planned on keeping the engine for a while, and making big power i wouldn't do it.

i read j-rat's thread, that really blows
kabooski posted a good pic of the spot
i had the option of buying good used 4 port irons from a guy but now i think i will pull a s5 6 port block i know of and try to use those irons.
i'll make a post when i complete it...prob won't be until next summer =P i just started my senior year of college

To mate the TII lower to 6-port irons I fabricated an adapter plate. Using an adapter plate allows for blending the transition where the runner splits from single to double ports, and also allows port matching to both the manifold and iron.
