Hi Rose money,
yes I think it is a good kit to buy, and since u have Tb-Evo, most of the plastic parts are same and like TB-evo kit.....no hop-ups.
Parts will be coming soon.
Comparing the price with V-one-S/R or mugen or yok, I think this kit is the most value for money.
And I had Built one for a friend ......and try it with the stock seting, I must said I it is not a bad car.
As for engine...usually rear exhast engine would be better than a side....but some kits like TG10R can only use side.
But unless U play at places like P.A. ....rear or side would not make too much a difference. But the pipe and engine timing make a lot of difference.
I had try OS 12cvr, Nova c-12 , RB c-12 and nova mega sx-12.
most powerful is RB but most driveable at carparks would be OS.
Nova-rossi's TP-02 pipe I find it good and can buy the team-magic TG10 mainfold from rotor.(All this is my personal op.)
Price I cannot comment much engine $220-$280 pipe $69 mainfold $19
Lastly, there is a tamiya gas car race on 28 oct
hope to see u there.
