I'm at work right now on brake and seeing your 850^^^ makes me miss my 850...1993 5-speed
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!
How about marketing an 850 ITB kit for the rest of us?
Glad to see its still out and about! Thats a pretty cool gearbox. Are you able to get a replacement part or will you have something made?
We have been running our 850 endurance racer a few races per year. It needs some hp for sure.
Hows the 242?
I know you put together the motor a long time ago but are you still running the early style VVIS head with the RN block?
I have been trying to decide what head I should be running on our endurance racer,
From what I can tell, the consensus knowledge is that the RN heads are better than the N heads. There aren't many people running a non turbo car and trying to go fast. I know that the results of having a NA RN motor in our car with a m4.4 and the intake VVT not being controlled is not good. We are trying to decide if we should go with a standalone and beable to have full control of the VVT system or perhaps but a N head on RN block?
Sorry never saw your reply..I know you put together the motor a long time ago but are you still running the early style VVIS head with the RN block?

Cars been sidelined, unfortunately. We are hoping to get back to it shortly to make some progress.Sorry never saw your reply..
Guess you are sorted by now? With M4.4 personally I would stay with fixed cams. The RN head is more efficient partly due to VVT which bring wider torque spread but the duration of those cams, which are different compared to N cams, is very short. If the gearing of your car is a good match to a certain rev range a fixed cam would be OK but not the stock VVT cam locked. Standalone are some new players now. I used Link with the SDM and nowadays they have some nice systems which can do VVT and ETB but there is also MAXXecu being used a lot for Volvo's.
