I have a MP9 lying around and will convert it to GT3. I am not to keen on getting the cnc shock towers because of the prices(have various projects ongoing and have been over budget so far). I

would really apriciate if someone could scan the shock towers and send it. I usually make parts from carbonfiber and having the 1:1 size would be viable to make it. I made an adaptation from GT2 towers but they seem to be taller than the GT3.

As far as I know, the 'GT2' is the same steering/diff units as a 'GT1' AKA '7.5 chassis'. The '777 chassis' still used the original diffs but the 777 steering was unique....with better handling. The 777 style steering occurs on the 'Route 246 chassis' option.
That's a long chassis. 7.5 steering doesn't quite match up to 777 chassis without 'McGyver Skill Level 3'.

GT3 is based on the MP9/TK14 and has different steering/diffs/carriers/etc. So the GT/GT2 is not 'mix and match' with the GT3.
A quick identifier is to look at the steering 'head plate'. The back line of the 7.5 is slightly curved.....the 777 plate is more 'straight'.....the GT3/MP9 is very different and more of a triangle looking thing.

Looking to buy a GT3 and I dont know too much about engines. I wanna do OS I think because they are pretty popular unless someone has other opinions. Here are the models....

Speed 21XZ-GT
Practical rpm: 4,000-42,000
Power Output: 2.61 hp/2.65 ps @ 34,000 rpm

Speed R2102 Engine
Practical RPM: 4,000-45,000
Power Output: 2.8 ps/2.76 hp @ 33,000 rpm

Speed R2103
RPM Range: 4,000-45,000
Output: 2.76 hp @ 33,000 rpm

R21
Practical RPM: 4,000-44,000
Power Output: 2.71 hp @ 32,000 rpm

Speed 21XZ-B Spec III
Practical rpm: 4,000-42,000
Power Output: 2.61 hp/2.65 ps @ 34,000 rpm

I want the best and most powerful. I want the car to be as fast as possible without money being a factor. i also heard Novarossi is a badass engine too. I would def be open to those. Just dont know which one to pick. Kyosho states rear muffler.for the GT3. SO guys...let me hear it.....

I haven't used OS engines basically for the increased cost. I do know they are high quality and good performance.
I've used the Nova .21 5 port 'P5' variants with very happy results (easy breakin/idle/lifespan) Mine is 'tweaked' by one of the many engine builders available (TNS). I've noticed that on the straight, it's still building on top end against some other engines.

The performance specs on your OS picks are so close that unless you are a 'hot dog tuner', you'll never notice the difference. A good tuner can take a Nova P5 and run with you all day. A bad tune can turn an OS costing over a hundred dollars more than the Nova into junk quickly.

In checking your info for comparison, I notice that Amain Hobbies added a new listing/variant of the P5 just a couple days ago.
It has the 'silver' crankcase (I prefer black) and it shows a bit more basic rpm output from what mine started out. Under $200us it's very attractive.

You didn't mention where you run but I have to use the '5 port/7 mm inlet max' for ROAR race rules. The engines are 'rear exhaust' but with the 'U shaped' manifold, the muffler ends up along 'side' of engine.

All of my Kyoshos have been GT/GT2....7.5 or 777 type chassis. I talked with an 'offroader' that was running the new MP9 at the time and he said it had noticable benefits in performance over the buggy he had run before. I know that unless you get the benefit of 'caster reduction' the cars out of the factory don't turn in the corners as well as the manufacturers that have fixed that problem already. Kyosho came out with the fix that you can buy. (I don't know if car has been updated to include new steering carriers as it really should) I had an engineer work on the design for me but a guy named Wkloppen (on rctech) actually got to talk with someone at Kyosho to get it to happen. I had already given up on getting them and changed to another car. I've got a set of the new carriers now and still want to try them on a '777 chassis GT'. Supposedly, the new caster fix works on 7.5, 777 and GT3/MP9 cars.

does kyosho still support the gt2?
the gt3
-does it now come standard with the 4degree camber?
-who makes rubber slicks for it in multiple race proven compounds?
-any other useful racing body for it other than the vette?

thanks

Looks to me the 4deg caster blocks are still an option part. GRP tires are usually very good.

checkout kyosho America's setups page

the typical 100K/15K front/rear would likely work fine

great, I'll have a look. Any other options that are must have on the initial build? The plastic servo horns decent? Gearing is probably not the taller set, per the manual.

No speed gear option for the gt3, only for the gt2. I wonder whose experimented with other gears and clutch assemblies. This really sucks.
