Raami Posted January 28, 2012 Share Posted January 28, 2012 Hi mate I have seen a man in japan do it with a single cam rb20 head , but he made a new timing chane cover and made the oil reterns line up in the rear of the head . but my version is a race setup and i wonted a dry sump so i went a diffrent path, as i had made the frunt cover redundent i hade to make the sump shorter , and i wonted even water temps along the hole motor so i started from scrach ... So your idear sounds a lot more practical ,and hope it all works out the chamber is so large on the TC RB its hard to get the comp up for a NA ,thats the reasion i had to go so big with the stroker kit , and the piston still needs a 18cc bump to get the comp where i need it , Hi. I have to mod the timing chain cover too but not that much actually. The oil is returning from the rear of the head but also from the front because I'm gonna stay with chain so it doesn't matter if the oil is going that way too. That returning oil is also lubricating the chain. But there are still alot to do that I can get the timing chain work. Also the cooling is one thing. Thinking how to get the coolant flow even because that rb-head has water outlet in the side of the head. I hope this topic gets good conversation from this subject and I will not hold any information from my mod if someone has something to ask.

Mate its a big job to make it all work ,but i love the chalange and know how well it will work .i have done 3 4 cylinder L20 twin cams with the KA head and they make incredable hp NA with a port that flows the same numbers as my head .So id love to see how you go with your build. I will get pics up real soon .. Quote Link to comment Share on other sites More sharing options...

No one but Simon seems to like my engine Bah ha ha ha Look at all us newbies on the American forum. Lol Few world class engines hidden down under! And I don't like it Jake. That's why I'm going to swap it with my PMC L30 Quote Link to comment Share on other sites More sharing options...

Joeoski Posted March 11, 2012 Share Posted March 11, 2012 Any planes on making a gear drive for the L6 to RB26 head ? Quote Link to comment Share on other sites More sharing options...
WanganDevilZ Posted March 12, 2012 Share Posted March 12, 2012 (edited) L28 with Rb26 head? Nice! Not exactly digging the back and forth between the two shops, as both produce some beefy motors, but better than my garage none-the-less!

PMC raceengines Posted April 11, 2012 Author Share Posted April 11, 2012 When on the dyno the other day , i found no5cylinder was not the same temp as the rest so i got to thinking, how do i fix this not just mask the problem . i know there is a thred with 24 pages off help but i need to realy fix this, not just do things that help so i cut up a p90 to get a good look for my self and found a fix, and hear are some pics So back on the dyno what happend , more power and more timing and all plugs look the same , and the engine was crisp Quote Link to comment Share on other sites More sharing options...
