Default Is this engine any good?

Well It looks like I am getting into 1/8th scale gas. I wasn't expecting to any time soon but I couldn't pass up this deal. Buddy at my track sold me a MRX-3 with a Novamega SX 21 Evo 4 and a bunch of parts for 200 bucks! My question is : Is this engine any good? I know its an older engine but it has a new rod and fresh pinch. What I mean to say is, was the engine when it was new any good...?

The Evo 4 is plenty fast. Nice purchase, the MRX-3 is a great car.

nice ride.... you and me were in the same situation i guess?... i couldnt pass up a 1/8 mrx4 with servos and evo 5 engine for 500 sgd when the chassis itself costs 900sgd here in singapore. maybe you could change the air filter to the on road one? less restrictive = a small bit of power.... heh...

Man, $200 for all of that is a good deal. As far as the air filter is concerned, you should check out the Mugen "Airbooster" Air Filter (part #B0010). Good luck in 1/8th scale.

Sweet deal, good on you. Take that fuel filter off, you do not need it.

Right, that's a Mugen pressure chamber. Leave it on, but you could shorten the line. Whole Idea is to dampen pulses without the need for longer pressure line.

I guess you can leave it on if you like but, all the 1/8 scales I see have the line directly in. Thats just one more thing that can go wrong"leak, clog".Which is bad for the engine..002

Well I installed the radio equipment today and fired up the engine for a bit of parking lot testing. WOW...engine runs great. Idles forever and winds up fast. This thing is ballistic. When the guy at the hobby shop said "You know the 1/8th is going to ruin 1/10 touring for you" I now see what he meant lol. Cant wait to get to the track next weekend!!
