Status: offline 		I thought I had seen these here somewhere before (heck, I thought I GOT them from here lol) but I did multiple searches and came up with nothing so here they are for the world to see once again in their full-color glory!








I dunno how well this is going to work for posting them, if anyone wants the originals let me know.

Also, here are some pics of the porting job I did on my old savage .25... it went from "Yah this truck is fun" to "Holy crap! It's ALIVE!!!"

Status: offline 		Thanks, when I had originally found them I read them 20 times in a 1 week period debating on whether to give it a shot or not. In the end, I figured "I've got enough cash to buy another motor if this goes sour so I'll do it". And it turns out, it saved me $200 on buy a was .26. Sure I had to go and buy bits for my dremel, but that's negligable in comparison. Plus it was a good learning process for me as to how nitro engines work. My buddy also had me do his old tired motor out of his Nitro RS4 2 and it gave that thing new life as well. Course he blew that one up doing donuts in his driveway full-throttle non-stop lol.

Status: offline 		to late i already did it. iv ported a set of 289 ford heads and gasket matched them so i kinda know how to handle a dremal and a die grinder. this little sleve cuts much faster than cast iron. and NO i did'nt use a die grinder for this the tune on the car is a little on the rich side,but its safer that way. its to fast for my driving skill as it is, but its raining and i dont have anything else to do

Status: offline 		Yeah it's just a general guide line for porting and is not meant to be used to try and adjust the timing of the engine.

Status: offline 		for starters, I don't want this thread to turn into a "You shouldn't do it because..." thread. I wanted this here for those who were looking for info on the technique to porting, not the pros and cons of. There's enough post out there already that debate it. Lets just leave this one to "Tips, Tricks and How-to" for those that want to try it. I was a noob my first time in (although I am good with my hands like that) but still, I knew nothing about what I was doing before I jumped into it. Besides, most people that are going to attempt this are going to try it on dime-a-dozen motors not $300 Sirio's, so worst case scenario is a new sleeve/piston/rod set or a gently used motor off ebay. Heck for that matter, NEW motors can be found for $50+ so why NOT try it just to say you did?

And nitro, have you gotten a chance to run it after porting yet? How'd it turn out? Take any pics?

PS: Just bought my first on-road RS4 18ss (used) and you can bet dollars to tire donuts that I'll be porting it too

Status: offline 		Ohhh by no means did I want it to become a "you cant do this or you cant do that" type of thread. It's a good article about how to port an engine, and most people should try it on a motor that they dont care about before they try it on a high dollar mill. I was just simply saying dont try and adjust the timing of the engine, I felt this is a good tip to epople that are trying to port and that where thinking of changing the port timing.

Status: offline 		Sorry 125cchyperman, that wasn't directed at you. I just wanted to make sure it was known the intentions of this thread before it started going sour.

But as the article states, Sport and midline engines stand to make the most gains. Well for most of us, sport and mid-line engines are what come with the vehicles. To be honest, I don't see the point of performing this kind of work on a higher-dollar motor unless you are racing. In which case, if you are serious about racing a)you leave the port work up to a company like RBMods or b) You are really good at doing it yourself and the article I posted is already a well-known fact to you.

supertib - holy CRAP?! Makes my job look like my 4-yr-old did it with egg-beaters lol Nice job, how'd it turn out for you performance wise? Which motor was that for and did the sleeve originally have that big notch in the base or is that an extreme mod-job?

Is there a similar article for the crank mods?
