What 20b "#" do you have?
 
Just curious what number does you engine have on it?
you will find the number stamped on the front rotor housing.
lets gather some info here on run numbers etc.
it will be either a number or a letter followed by a number.
my number is 454

mine says 2 0 b

:D

(I wish...)

Mine says 421. The highest number I saw was I think the Mazdatrix drag car where it was in the 9XX range.

Also if these numbers are actually the serial number for the engine, then how many 20B's where actually produced? Anybody has that info?

Jeff20B 08-23-02 02:52 AM

Which numbers were used from series one to series two? Weren't the series 2 engines slightly stronger?

come on guys how hard is it to look see what number is on your motor.. there is a point to my question which I will get to later..

matt

mad20b 08-23-02 09:39 PM

A 021 - one of the very first i believe!

now 08-23-02 10:05 PM

HyperRex 08-26-02 07:00 AM

RETed 08-27-02 08:24 PM

Would be nice to hear from:
Attila the Fun
to see what number is on his motor...

matt

RETed 08-28-02 09:32 PM

Actually scratch that - the number "555" was painted all over the motor, but the front plate actually had "669" stamped on it.

the series number is on the front rotor housing
not on the cast iron parts, now if you have rebuilt and
used 3rd gen housings you will no longer have the number.

matt

Bitchn7 08-29-02 02:16 AM

Mine has 757 on the front and rear rotor housing, couldn't see the second housing but I think thats the housing we replaced anyway.
is the number supposed to be on all housings or just the front one??
I believe 9000 20B JC Cosmo's were made, how many extra engines were built is another story.

j9fd3s 08-29-02 11:21 AM

they still sell the engines too. NF01-02-200 list $7500.00

mike

Jeff20B 08-29-02 02:01 PM

How does that price compare with other engines capable of similar power? I think the Supra inline 6 can do like 1000HP or something. How much do they cost new?

now 08-30-02 08:15 PM

guess i was wrong, the numbers are stamped on all the
rotor housings, not just the front one.

matt

Jeff20B 08-31-02 12:28 AM

I saw a 20B with the numbers stamped on all three too. It was 7xx (only glanced at it).

now 10-08-02 12:16 AM

I now have a B991 as well:)
Will be working on the rebuild over the next while and
should end up with a good reliable block.
i am happy now:)

later
