should be able to fit most big blocks (i.e. .21ci/3.4ccand up) be mindful of the drivetrain, to much power will blow them out alot more regularly.
thunder tiger is having sales on their engines, they have the .28 version of what you have for around 100$
 
Okay thank you for your help!! Would I notice a big difference between the 21 and 28 engine I was thinking about getting a 32
 
there would be a big difference between the .21 and the .28. especially in that size of a rig. imo for that vehicle the .32 (I'm guessing LRP ?) would be way to much. usually people put the .32 on monster trucks like the LST/MGT/Savage, weighing in around 13-15lb mark, spinning 5-6" tall and heavy wheels and tires. the .32 seems for many to be a great engine but imo wayyy to much for that rig.

2.4 bhp vs 2.1 bhp.
never hurts to run it if thats the way you want to go. drivetrain will definitely need some love though.
i was happy with the axial .28 motor in my MGT and it weighs in near the 15lb mark, though i dont normally go for wheelies etc. but i also have only run almost 2 quarts through it including break in so i dont have it full performance yet. having a hard time pinpointing bhp for it.
 
Okay I just want alot of power aha would a 1/8 scale with a 32 engine be crazy
 
1/8th buggy, yes that would be insane lol, 1/8th monster, still quite a lot.
also another thing that is inherent with larger motors is they are quite thirsty.
 
I'm thinking of a 28 engine will rip I just don't want to get bored with the power what's the fuel like on the 28 engines I'm getting around 20 mine at the moment on my 21 engine lol
 
i would probably say around 15 minutes then, really depends on how lead footed and the size of the tank.
 
I have a 125ml tank my head on my nitro engine stripped where the glow plug Goes
 
that is a single piece head correct? ie when you take the head off there isn't a separate plate where the glow plug threads?
also that is a 6 screw head right?
 
Yeah that's correct mate and yes it's 6 bolts
 
Okay would this head definitely fit my thunder Tiger S2 Pro 21 thanks
 
i can take some pictures and measurements off the head i took off my engine to compare. i really want to say yes, but confirmation doesn't hurt, part number for the TT head is AA0354P i do not know what the bottom of the head on yours looks like.
 
95224
 
i was more meaning the underside of the head when you pull it off. as if you were looking at the bottom of the glow plug when it is installed. careful not to lose/bend the head shims when doing this. they are thing and if you pinch them weird they bend easy.
(also i find it kind of funny that I'm running the same exact pipe with what I'm expecting is the same engine on a totally different rig.)
 
I can show you photos of under soon if that's more helpful
 
There u go mate

the bottom looks exactly the same, when i get off work i can go take some bolt pattern measurements and double check depth of the button on the bottom.
