Looks like it's a three port sleeve, huh?

Did you have a hard time getting the rod out? I couldn't get it out which I why I didn't have any internal pics. Also, note the cut on the exhaust port on the case. Pretty trick.

yes just like os v spec/speeds

yes it was tight and so was crank it was snug tight tolerances and the exhaust port was matched very nice

i have both os pipes and plan to start there so as soon as i get this thing broke in i will post i really think this motor will rock

well we have been having a great break in the weather 60+ so got the motor all broke in its very very tight and plus 3 tanks at rich and then i started tuning on it with a os 2060 and od97t plug all i can say is wow the motor rips and i belive 10+ run time and the nuts havent even droped i dont think any body will be diapointed in this motor i have a big races in dallas in a week so i will post and let you guys know how that went

Just ordered my first Arrow GTR .21 Engine today. Cant wait!!!

i put a p/r/s in a speed case.. at 98 bucks for p/r/s compared to 169.00 for sleeve and piston and 47 for the rod from os.. 98 bucks looks a lot better in the pocket book... all the specs are the same as a v-spec... the case and back plate are a tade different but ALL the other pieces are the EXACT same as a v-spec..... jeremy

ps.. answer-rc has all the parts and motors in stock... talk to mike for questions

well motor ran great this weekend never got above 230 all weekend ran a 2060 with it got 12+ runtime no joke i won and tqed both int buggy and truggy at the ice breaker this weeken in texas 150 total racers 35 int buggys and 20 truggys i won 625 bones

so i have around 1 1/2 to 2 gallons on this motor and you still cant roll bye hand this thing has just preformed flawlessly

Talked with Mike at Motorama and brought one home to play with. I should have porting and performance results for you guys soon. It is laid out very close to the V-spec as most have mentioned and it should run awesome with some race porting. The stock ones looked really good at motorama so I am very interested in seeing what I can come up with for them. I am also interested in seeing how the new hardened crank works out. If it has a nice wear to it and if the carb is decent, it should be a very nice engine for the money. I will keep you guys posted!

Hello Guys,here are some pics of my car with the GTR engine...







I have almost 2 gallons through the engine,it is great so far,zero flameouts,easy to tune,i would say it has more power than the standard Vspec and just a bit less than the speed,quality of the parts is actually great,so i would say it is a really good engine,overall...

That's a pretty sexy engine..

A yery interesting engine, I have to admit.
Which pipes are you running/which are recommended?
Any words on fuel economy?

.Well got my motor all mounted and in place for break in. Hopefully. Can start today. I've heard all great news about this motor and I'm lookin forward to puttin it on the track.
