rx7 86-91 13b non turbo 6 port used engine front iron housing/plate/steel RESURFACED


Out of stock



rx7 86-91 13b non turbo 6 port used engine front iron housing/plate/stee. Technically this is an 89-91 front iron that uses the double front cover o-ring setup but it is a direct swap for 86-88 models as well (and technically an upgrade).

This one has been sent to rotary science in va for face resurfacing and has zero measurable wear on the face. RS does not reapply the original nitride hardness treatment, these are lapped/ground only. Otherwise they are dirty and unprepared as-removed from core engines and need the normal cleaning and prep processes before use. Appears to have a stock untouched intake port. As close to new as you can get, especially since at times (or maybe forever?) these are NLA/backordered new from mazda….and even when they were/are available new, the cost is about $500 plus shipping.

Shipping to the US48 only at the shipping price displayed. I can ship to AK/HI/PR but for now I am unable to set up automated shipping calculation to these areas so you will have to contact me directly to set up purchase.

I do combine shipping when possible on multiple item purchases. Due to the wide variation in size/weight/shape of items I have available, I’m unable to set up the system to auto calculate these combinations. So, each item gets purchased at standard shipping price, and when the packaging and shipping is done, any overpayment for combined shipping will be manually refunded to you. Sorry for any inconvenience, but at this time, this is the best way I know to handle the issue.
