The Build:
All of my engines are built on a per-order basis, meaning that I do not have any stock on the shelf. There is approximately a 2-5 week wait between the time I receive your initial deposit and the time I ship the engine back out.

ALL of my engines receive the following:

-atkins 2mm 2pc apex seals, unless otherwise specified (2pc design more stable than stock, softer material breaks in faster with used housings)

-oem mazda inner and outer coolant seals, dowelpin orings, tension bolt seals, front cover oring(s), rear stationary gear oring

-atkins thermal pellet replacement (front of eccentric shaft)

-93-95 corner seal springs, upgrade from stock 1991 and prior wire style

-atkins viton oil control o-rings (upgrade from stock)

-Mazda OEM front and rear main seals

If your engine requires hard part replacement (iron plates, rotors, housings) these are replaced from my own core stock (if available) at extra cost to the customer, usually $100-200 per part depending on year/model/condition/availability.

All engines are also painted, AT NO ADDITIONAL COST, in an alternating paint scheme, irons in black ( or another color of your choosing) and rotorhousings/front covers in gunmetal (or another color of your choosing).

This gunmetal is a change from my traditional paint scheme, and Im not aware of any other supplier in the industry using it. This combo seems to be impervious to heat and dirt, so I feel it makes for a cleaner looking engine bay after a little time has passed. The silver is still available, if you wish to have this instead. IF you wish, you can choose other colors or schemes for your engine (anything readily available in engine paint colors). Keep in mind light colors do not fair well in an engine bay for more than a couple of months...black is the best choice. Painting the whole block a single color usually does not look too good, but I will do whatever you instruct.

You also have the following options for your engine:

*Upgrade to mazda OEM apex seals instead of atkins. Mazda has done hands down the most research and development on seals, and builders worldwide swear by stock seals for street and race applications. Though atkins seals are certainly high quality and build a nice engine, most would agree they are not quite as strong and do not take quite as much abuse as OEM seals. EXTRA cost for upgrading to mazda oem 2mm 2pc seals is $125.

*Gasket installation kit. Includes all external gaskets and most o-rings appropriate to your specific year/model of engine. Extra cost varies by engine model, see PRICES page.

*3mm seal upgrade. Includes atkins 3mm 2pc apex seals (instead of 2mm), new 3mm apex springs (single spring), atkins 3mm solid corner seals, 93-95 corner seal springs, and rotor milling to accept 3mm seals. Recommended for owners who are particularly hard on their cars, or for owners of modified turbo engines who may make a few tuning mistakes along the way. Note that this may add 1-2 weeks of wait time to your order, as the machinist I use does this work on the side and cannot always get right to the work I bring him. Check for availability first if this is a problem for you. Total cost $400, in addition to other costs.

* Cermet B ceramic resurfaced rotorhousings, when available. These are used housings that are precisely ground down to remove the old chrome coating to the depth of the lowest imperfection, then the surface is built back up with Cermet B, a version of ceramic coating. This is a very slick coating with good heat rejection properties. It is stronger than the stock chrome and should result in more power due to less friction, lower coolant temps due to heat rejection, and better compression for a longer period of time due to strength. $800/set with your useable core exchange (badly damaged rotorhousings cannot be repaired) or $1000/set without core. (if yours are too badly torn up to repair, or if you wish to keep them). Using these will result in greater compression (versus used housings) both initially and after breakin, and generally make for a smoother, better running engine.

*New oem rotorhousings. Great upgrade from worn used housings, will result in greater compression (versus used housings) both initially and after breakin, and generally make for a smoother, better running engine. $1050/set.
