400whp Msp Build UP

Steve, I thought the cryo treatment places heat up the gears and then do quenching with a slow quench to -300. IF they don't do the heating, then I'd agree with Turf and save your money.

Each place does it different... some do it before the cryo, some do it after, some don't do it at all... the big question becomes what temp and for how long... and a slow quench is actually completely useless... that makes material weaker as it lets full grain structures appear... a full heat and slow quench air cool is just annealing...
Annealing
[size=-1] A comprehensive term used to describe the heating and cooling cycle of steel in the solid state. The term annealing usually implies relatively slow cooling. In annealing, the temperature of the operation, the rate of heating and cooling, and the time the metal is held at heat depend upon the composition, shape, and size of the steel product being treated, and the purpose of the treatment. The more important purposes for which steel is annealed are as follows: to remove stresses; to induce softness; to alter ductility, toughness, electric, magnetic, or other physical and mechanical properties; to change the crystalline structure; to remove gases; and to produce a definite microstructure.

So unless they quench it you are likely driving yourself in the wrong direction, or they aren't getting it hot enough to matter...

here is some more on heat treating and tempering:

[size=-1] Verb, the adjustment of temper. In ferrous metalurgy tempering is the reheating of steel to some temperature below the hardening temperature after hardening in order to reduce the brittleness which also reduces the hardness. The tempering range for steel is from 350F (177C) to as high as 1350F (732C). It is recommended to temper almost all ferrous metals after hardening. See heat treating. In non-ferrous metals the temper (hardness) is adjusted by heat treating, aging or work hardening. See references on specific metals for methods.

[size=-1] Reheating quenched steel to a temperature below the critical range, followed by any desired rate of cooling. Tempering is done to relieve quenching stresses, or to develop desired strength characteristics.

[size=-1] The process of heating and cooling chocolate to a specific temperature causing the growth of stable crystals, resulting in the formation of hard, shiny chocolate.

[size=-1] Re-heating a quench-hardened or normalized ferrous alloy to a temperature below the transformation range and then cooling at any rate desired. In heat treatment, re-heating hardened steel to some temperature below the A1 temperature for the purpose of decreasing hardness and/or increasing toughness.

And keep in mind that when you talk aluminum and you say T5 or T6 or T3 you are talking about which heat treatment it has undegone...

My shift forks are pretty beat and my snychros are all but gone in 1 and 2. This is why I am seeking a beefy tranny. I just want something that can take some abuse and that will last.

The newer stock revision parts should get you there.. word is the new synchros have been additionally heat treated... how are your forks beat??

The mazdaspeed tranny you mean? Or was it just anything built after that 02 date?

It was somewhere in 3.5 I think... maybe 2.5... but they superceded all parts with a new part number that has the improvements.. I have the forks... the part numbers are around somewhere...

How new are the newest synchros?

fork part number? Maybe I should just source an msp tranny because lsd would be niiiiice.

I keyworded it.. so I'll do a search for it...

The LSD is nice.. you can get it for 440 from mazdastuff.com or slightly cheaper...

if you can find a wrecked tranny that has the LSD in it that would be awesome.. but good luck on that one! then they can only ship it truck freight which is like 100 bucks..

and
GC01-17-40XA

No we don't really do any tranny work... I have sources that can do it.. and I can weld MSP LSD's if you want it done like I did... but that's about it!
 
I take it you just welding the msp lsd to your mp3 tranny?

thanks for the info on forks. I am looking to have some work done relatively soon so I might PM you.

No... I welded the two halves and the ring gear of the MSP LSD further to ensure that it can't shear in half like some people had seen with the LSD's. No one has talked about that happening in a while.. so it may have been a fluke, but I'm sure my tranny is plenty strong at this point! :)

I'll look for the PM... we are probably getting OT now... so we should leave this topic be.
 
So what happened? Did it blow up? Still running strong? Are the myths of 400whp impossible out of a protege true?
 
Nope its still running strong, i just got the 1000mile tune up, and everything is good...were just waiting on a few more things, and when i get some time off of work and school to put it on the dyno. But let me tell you it pulls like a beast when i get traction on on warm day... were trying to make some changes on the car to get better traction also..
