CEN MATRIX FRE
some asked if this would be a good engine for a cen matrix.
Here is te explaination of Ninja/GRP
Mugen Seiki broke the contract with GRP because they were having problems with Ninja engines preaturely failing and not performing. GRP was also making their own engine line and it was the same engines as Ninja so Mugen Seiki went to O.S. to have them design and make them engines,so basically do not buy the grp version ninja.
There were two lines of ninjas.
A regular MR Ninja and a MRT Ninja
The regular ninja is the most common.
They made the following:
MR12T01A for on road touring car
MR21B01A for off road Buggy/Truggy
MR21R01A For 1/8th scale on road
MR28M01A for monster truck/truggy
The tuned they made
MR12T01AT Tuned for on road touring car. This engine never really sold well but isnt uncommon.
MR21B01AT Tuned for off road Buggy/Truggy. This engine sold decently but like all of the others they werent out very long.
MR21R01AT Tuned For 1/8th scale on road. This is most likely the most popular as the Mugen Team raced with these. They also did very poorly and caused many DNFs and loss's for Mugen cause of its unreliability and failures. They primarily developed the Tuned line off these as this is what engine they started on.
They never released the MR28M01AT Tuned .28 engine.
The Tuned ninja line didnt last very long because Mugen went elsewhere looking for a Ninja engine manufacturer. They are now with OS. The os is the JX21B01. GRP started its own line of engines which are the exact same engines as the Ninjas except have a different cooling head and name on them. They have yet to release and Regular engines but have instead just release Tuned versions. Every single GRP engine says TUNED on them and are exactly the same as the Tuned ninjas. Some people are saying they have differnt parts and timing than ninjas and that is because they are comparing a Tuned verson to a regular version. Compare a Tuned Ninja to a GRP engine and youll see the exact same thing. The only difference other than the cosmetics is the GRPs have the super Alloy head and the Ninjas had mostly the Magnesium head. Ninjas switched to the Super Alloy head on the on road engines to try and help with reliability and tuning problems but that was done right after Mugen and GRP terminated their partnership.
Summary
MR12T01AT Tuned=GRP Tuned GT01-12TC
MR21B01AT Tuned=GRP Tuned GT01-21BU
MR21R01AT Tuned=GRP Tuned GT01-21ON
and what would have been the MRT28M01A had it ever made final production would be the same as the GRP Tuned GT01-28TR
The GRP Tuned GT01-21RA Was never in the Ninja linup. Its most likely just the GRP 21 buggy engines with a changed timing profile to have a better power curve for the RALLY GAME Racing class thats big in europe.

RE: CEN MATRIX FRE
I have a Matrix and the stock SH28 is kind of a pain. I see SH has a website now and are cranking out all kinds of engines and parts. I would stick with a long saleslife .28, something with a track record. I think buying a engine because it is the cheapest from china is asking for it, like CEN seemed to do with the SH28. They probably will improve but my next engine will be a name brand with some history of value.
