So I am going with the esp 34cc kit with the ported head on my losi 5T 2.0. I am also getting the high rev piston.

Is it worth getting the 0.15 copper cylinder gasket or am I pushing it? Or should I go with the 0.3mm gasket?

I will be running the car on 100 octane.


Here are the part list that I will be purchasing

Do it if you want but your spending more money and most likely losing a bit of power

Not necessarily. If it is setup to run on this and you run low octane pump gas in it? You may detonate it hard and cause damage. We recommend 100LL or c9 in the engines we manufacture. Run pump gas in it while running it like it is hard. You will detonate it bad.

So am I. They say both Doug and Ddm recommend it. If it is being recommend by an engine modder/builder. Why do people always want to NOT do what is recommended. Than complain how it just failed for no reason. Engine builders do it for a reason because it is what is needed to make it work or survive. That would be like buying a top fuel blown alcohol drag engine and saying "I am just going to run 87 pump gas in it." If an engine is recommended to run on a certain fuel or oil combination. There is a reason. I have had so many times where people run crap oil ,wrong fuel or changes things before they even run it because they were told by someone else to do so. Than I get stuck on the phone almost a month almost daily dealing with why it doesn't work and is engines fault. Until they finally tell me what got switched. Tell them to run what we recommended and than see what happens. They call back problem solved and can't believe same engine.

Dude it’s a $250 toy engine not a $25000 race engine. The compression ratio isn’t high enough to warrant using high octane gas it’s not about recommendations or preferences it’s just simple facts. A g320 has a compression ratio of about 9.2:1. Which is below the recommended compression ratio for an engine running on 87 which is 9.3:1 or less. An engine running 100 octane should have at least 12:1 compression. Running 100 in a zenoah 2 stroke will not give you any benefits over running 87. Not sure what’s wrong with you but it’s definitely not nothing🤣
