Renesis 4-Port Manual Trans Rear Iron Side Plate
 
While the rear iron side plate for the 5-spd 4-port engine was never sent to the USDM on a production vehicle, it can still be purchased and imported/shipped from Japan.

Just documenting the part number here for future reference:


Part No. N3H1-10-C50

the 5speed trans bolts right up to our 6 port engines i have one. no need to order a rear plate. and the 4 port manual engines from japan bolt right up to the 6 speed trans usa models. if any one thought differently

I think he is saying more so for people buying the 4 port auto for a turbo build, I assume you need a 4 port manual rear iron for a manual trans? I am unsure though just speculating.

I literally stumble on 3 sets of 4 port manual plates in my garage. Can't see what is so desirable in them; their exhaust ports open later and as such are even smaller than those on 6 ports.

Want to know how they do as NA.... well:

at least somebody around here uses their cranial function … but there is the option of using a 6 port iron and plugging/sealing the Auxiliary port. Potentially with issues though since you can’t seal off the inner surface fully. Hence …

because not really any point asking someone in Romania to ship a used one compared to buying and shipping a new one from Japan. :suspect:

I’d probably want to pair the 4-port end plates up to a 6-port center though. Both the Sec & Exhaust ports on the end plates can be massaged to duplicate the 6-Port size/timing.
