How to spot the Mazda Factory Race parts
Ok, I thought it would be best to start alist, so to help people identify the factory race parts, mainly Rx7 ones from the 80's.
Oil Cooler # 1058 78 180 Larger than stock cooler and increases cooling by 50% over the standard type. The mountings are different, as your unable to mount directly under the radiator. This was the standard Competition Oil cooler for the Rx3 and Rx7 Standard type, 8 row. https://img34.imageshack.us/img34/764/img0841k.jpg MFR type, 11 row https://img545.imageshack.us/img545/8347/photo2ca.jpg https://img219.imageshack.us/img219/9075/photo3gt.jpg Oil Cooler Lines #4352 14 720 & 4352 14 730 https://img839.imageshack.us/img839/956/img0953te.jpg Rx7 Oil Sump # 4352 10 700 Twin Belly sump, as to increase capacity and maintain pressure under racing conditions, particularly while cornering. Holds an extra litre over a stand type. Standard Rx7 https://img30.imageshack.us/img30/151/img1013s.jpg MFR Rx7 https://img707.imageshack.us/img707/...new12asump.jpg Radiator # 1058 78 190 Aluminum construction,larger core and longer. This is to provide 60% cooling capacity over the stardard type. This was the standard Competition radiator for the Rx3 and Rx7. https://img341.imageshack.us/img341/2098/img0918yrd.jpg https://img835.imageshack.us/img835/5227/img0919kb.jpg Difference between a Rx3 12a Radiator and the MFR https://img850.imageshack.us/img850/6403/img0920a.jpg |
Front Strut Assembly # 4352 34 910B (R) #4352 34 960B (L)
Damper characteristics of the shock have been selected for racing and are adjustable. Have less travel, than shock and the stub axle is stonger for inceased durability and safety. (same are the Rx5, I believe?) Plus it has the bolt holes for the brake duct and made by KYB. (Note: In the competition catalog the left struct number is incorrect 4352 34 920) https://img411.imageshack.us/img411/...frstructna.jpg https://img27.imageshack.us/img27/2607/mfrstruct1.jpg https://img232.imageshack.us/img232/...tscomplete.jpg Front Springs # 4352 34 001 Lower length (252mm) to standard (338mm) and spring rating of 3.4kg/mm (standard 1.9kg/mm) Note the progessive rate on the tag https://img850.imageshack.us/img850/5409/photo9op.jpg https://img823.imageshack.us/img823/7048/photo7ny.jpg |

Great post! That knob is awesome. I need one of those lol.

Awesome thread, thanks for sharing all the pics and info!
How long have you been collecting these parts? |
INFO OVERLOAD :icon_tup:

On the gearbox; the MFR version look to be using a cast iron front cover instead of the stock aluminum SA covers; it that actually the case? Or is it just heavily discolored?

Ohhh, what do I want?
The LSD would be awesome, the shift knob, and the intake manifold would be freaking sweet to own. Only if I knew where to find these :( and lived on the west coast. |
