[@mcnitro874]

cylinder looks very similar to the os B21 I showed you bro❤ awesome

[@TastyBRC]

Yes similar, check my Ielasi dirt video, exact same piston and sleeve as your b2103 type R, its a very good engine

[@a2rc]

That’s an awesome number comparison and conversation at the end Tasty 💯 - It will be interesting to hear your thoughts on running the GT engine on a buggy Thanks for the vid 🩷

[@TastyBRC]

Thanks for watching! part 2 coming up soon!!

[@tonysands2837]

Beau moteur

[@TastyBRC]

Merci pour le commentaire David 👍

[@kings-racing]

This engine looks very nice. Really looking forward to see it run in the GT car on the onroad track. Those ifmar rules suck. Since you are not racing and a picco fan, may i suggest the picco monza 9😬 Excellent vid again buddy👊

[@TastyBRC]

Thank you Kings. You read my mind, I've been dreaming about that monza for months... And as we will dyno offroad engines, a GT engine , now we will need to dyno a onroad engine, otherwise our life will have no meaning

[@kawicepticon8866]

I run this engine and it ripppsssss!! I run with tall gearing 16/48 which smoothers it off the bottom but when she lights off it will pull the wheels off the ground in buggy at 30mph!! I have ran it in a truggy wiht a 14 bell and its a beast lol Id love to see you try it on track lol. The Ielasi gtr pipe set is reallllll good on it , not the one with the V3 manifold . Its better than 41032/9886, by far the best pipe set I have tried so far.I have the Capricorn version too and the ASM one but I havent ran them yet.Make sure you shim it for your fuel. I run .20 and rp7 on 30%-stock is .25 for "30"

[@kawicepticon8866]

OH yeah I yank the venturi ..on a 7mm its blahhhhh, I hate that rule. with a 7mm all the GT engines perform about the same. I can say that with confidence as I have 7 different Gt engines .

[@TastyBRC]

@@kawicepticon8866 Yes it Rips!!! I was impressed, part 2 is coming up! Now that it's fully broken in I will remove the .1 head shim and run .15 with my 18% fuel.. I only have 1 onroad pipe at the moment, the reds 2113 wich seems to be the perfect pipe for this engine

[@kawicepticon8866]

I run the 2113 attached to the Ielasi V3 gt manifold in my truggy that is attached to a Muran Reds 723...it runs fantastic with that setup. I haven't ran anything else on it yet bec its runs so damn good. Make sure you run a GT manifold with it . Looking forward to the next vid brother!! @@TastyBRC

[@thelag1200]

Great vid bro cant wait to see that gt car run

[@TastyBRC]

Thanks! Im still paying with this engine in the buggy 😁But the GT will be on the track next week 💥💥

[@adamsrcsandadventure700]

Nice engine bro👌 i have a r5r GT engine and it ripps in my buggy, very impressive

[@TastyBRC]

I didn't know there was a GT version of the R5R!! I love my offroad R5R, sure the GT is a great engine

[@colorado_a3766]

You think it'd be possible to take the crank from the ronda and put it in the r21 to get a longer stroke with a smaller close number?

[@TastyBRC]

I dont think so, these are different engines, different block, different bore and stroke.. maybe it will fit and you will have to check the piston clearance, reshim, but it would definitely be a downgrade, the r21 runs good but is not overpowered for a gt, I ordered a picco monza based engine really curious about that one. The fx g501 seems to run stronger, its now on the top of my wishlist

[@wesdex04]

Do you ever struggle getting the rod off the crank pin on new engines? Is there a trick to get the new tight ones to come loose. It makes me nervous everytime

[@TastyBRC]

I have a tool to remove the conrods! hudy 107021. New conrods are very tight on the pin, especially picco ones

[@konstantinosxarbilas6241]

Nice video, but I'm curious if there is a reason why the screw on the cooling head is loose???

[@TastyBRC]

You noticed! Thanks for watching till the end 😅 Thats probably my fault, didnt tightned that screw properly.. I noticed that durind the idle tanks.. luckily

[@konstantinosxarbilas6241]

@@TastyBRC thanks for answering. Nice video!!! Keep getting better and better!!!!

[@lukassslukasss1864]

Is it me, but I see the right screw not being tightened in the end of the video

[@TastyBRC]

It's not you! Its probably me not tightning that screw properly 😟I noticed after the first idle thanks ... Running video coming soon, all the screws are tight 😅
