TB Evo 3 Surikarn build

Recommended Posts

_09B35892.jpg

It's been a long time since I've posted a build thread on any forum. I do love to document my builds though and I think this seems like a great one to pick that back up with.

Before I explain the build, let me tell the story of how I ended up with these cars.

The first one is a funny story. A few years ago I spotted someone selling a complete joblot of cars on a local auction website. It caught my eye because it included a bodyshell I build years ago when I first started RC drifting; a pearl orange Nissan R34 Z-tune body that I've since sold to a friend. Turns out that friend sold it on together with one of his Surikarns to a guy not really interested in RC's and it changed hands a couple times after. I got lucky because the guy I bought it from didn't really know what he had so I ended up with a bargain of a deal. Plus I got my old Nissan body back B)

After inspecting the Surikarn chassis it turns out it wasn't 100% complete and also not in the best condition. One of the previous owners hacked up the upper and lower deck, probably to gain some extra flex. This sucks because the Surikarn originally actually came with a thicker chassis plate (3mm vs. 2.5mm) than the 'normal' TB evo 3 to stiffen it up; An upgrade now completely ruined.

It sat on the shelf for a long time until late last year when I decided I finally wanted to tackle the restoration of the Surikarn and pulled it apart. I was looking at buying a bag of brand new aluminium parts for it, but the auction went crazy and ended up more expensive than a perfect condition complete car I saw in another auction that ended a couple of times without any bids whatsoever... So I just bought the other car! That's how I got the second one.

I was still looking for a new bottom deck for the first car and bought a Square 3mm upgrade bottom deck. A day later I spotted an ever better upgrade, a complete K's Model Racing Factory carbon conversion for the TB Evo 3! So now I have two sets of upgraded carbon :D

The plan is to use the best parts of both cars together with the K's conversion to build, in my opinion, the ultimate TB Evo 3 :) 

Since the second car came with TRF418 suspension, I'll swap over the suspension parts from the old car onto the new one and maybe use whatever's left to build myself a TB Evo 3 Surikarn runner. Or maybe the TRF418 suspension can go on one of my TRF414's and I can sell the second Surikarn. We'll see.

Now for some more pretty pictures of the car and parts:

I started of by cleaning up the old car in my ultrasonic cleaner. Most of the plastic bits came out really nice.

Fun fact..

Did you know K's Model Racing Factory / Kai used to be (just like Tech Racing) designing and/or manufacturing some of the more special Tamiya prototypes or limited edition models? This is why I'm so excited about finding this rare K's Factory conversion kit. ;)

This is just lovely. What's the story behind the red parts? Why did tamiya go away from blue for this car?

Great looking chassis, I have one and it's one of my favourites the red parts really make it. 

I think it's the only touring car to come with titanium screws as standard.

Thanks! Tamiya did it as a limited edition release to celebrate Surikarn Chaidajsuriya's victory in the 2002 IFMAR World Championship and a year later his victory in the TITC. I think they just did it to make it more special. The regular TBevo3 wasn't blue anyway either, but grey. The TRF414M and some later option/upgrade parts for the TBevo3 were the first Tamiya chassis to get the signature TRF blue.

They also did the whole range of TRF tools (and toolbox) in red. I have the TRF setup board in red to go with this car, but I'd love to have the toolset as well someday.

I love the red, very unique! 

I picked up a very lightly used EVOIII for all of $60. Rear diff was blown, otherwise it was nearly mint. Rebuilt the diff with M05 ball diff parts and it's like new again. Still a great car! No fancy red though, it is indeed all gray.

Are both the Square & Ks Model plates 3mm?

T retailed both the EvoIII 2.5mm & 3mm chassis plates as SparePart or HopupOption.

Just a headsup that T also made 2 different plastic bumper mounts to suit the 2 chassis thicknesses :wacko: but they only retailed thinner one as SparePart.

Have only seen the thicker bumper part in Surikarn kit.

If you intermix a thicker chassis onto a normal car you'll get a dangerous ridge exposing the leading edge of chassis plate. (& vice versa, although don't know anybody who's put thinner plate onto a surikarn.)

Good to know! I have a spare TRF414 bumper mount. I wonder is that's different too. Would be nice to 3D print spare bumpermounts for the Surikarn then. 

The Square deck is 3mm, the K's I haven't checked yet. It will not be a runner anyway, or maybe only carefully.

I started assembling the chassis yesterday with the new K's chassis set. There's a lot of parts included in the K's conversion with some options to add extra stiffners to the chassis as well as a TRF414 transponder holder. The transponderholder I have, but the stiffners I need to find a sollution for because I would like to add them.

Before screwing all the parts to the chassis I layed them all out so you guys can have a good look :)

I will update with pictures of the build car soon. It won't be finished yet though, as I want to add a few more upgrades and little bits to make it look more pretty. I think this car deserves to get electrics installed as well for the full look.

Spend a few hours here and there in the evenings last week to start assembling the new Kai chassis.

There's a few things to figure out.

First of all if I want to keep some of the clearly used parts, or make it look like it's brand new. I always like the 'patina' or racing history character of used chassis', but since I'm adding so many new parts I'm not sure. For now I'll keep them on the car.

Second is if I will replace the screws. It's super cool that Tamiya released this kit with titanium screws as standard, but with this conversion I had to swap some out with different sizes and there's also a couple that are almost stripped. I'm thinking of maybe adding gold plated screws? My old red/black Yokomo DRB looked amazing with the gold screws.

Last there's the dampers.. Originally the Surikarn came with the grey fluorine coated TRF dampers, but the car I bought in Japan came with the more modern ribbed TRF dampers in all red (not sure if they are original Tamiya or maybe re-anodized?) I like originality, but I also like custom parts and the red looks pretty good. What to do?

Overall it's already starting to look pretty darn good B)B)

What do you guys think so far?

I think your right about the dampers being re anodized, the red trf damper set hop up has grey anodizing on the threaded section. Either the damper parts have been replaced with 49313 and 49314 or they've had the blue stripped off and done in red. 

Looking smart anyway 👍

As the cilinders are red too, I think they are re-anodized. At least the cilinders are anyway. I do have some red spring retainers I could add to it :)
