arrg, I just had some unexpected bills come in and I may need some extra money so I might have to sell these things when I get em. This sucks sooo much. I am sticking to my side of the deal though, I won't return em to RRM but I may, if I have to sell them to a member on here for less than what I got em for. I am so psyched for these things too. I am hoping things will work out in my favor but if not just giving anyone who may be intrested advanced notice. PM me if you are intrested and Ill get back to you as soo as I find out more.

Boe's motor is pretty much stock now. Regardless, it would be good enough to tune on.

EDITed.

 

Just got the pistons, they look real good, now I just need to decide what I am going to do !!!! arrr

I think what Rock was trying to say is that we can swap the pistons but our engines could run little bit lean on fuel which shouldn't be very harmful. Maybe, if you don't want a piggyback get a AFR widebang gauge and a fuel pressure regulator and adjust afr yourself.
Would that be right Rock??

 

Well, the way I understand it, the car will be unrunable. But maybe I'm reading too much into it.

Either way, I'm just annoyed that this is the first I hear of it.

 

mmm, most likely won't work well without more fuel. just adding a fpr will just make the motor "non-detonating" and may likely have spots in the powerband that are too rich. this may negate some of the gains. guys with the piggyback are likely the ones to benefit most. but who knows. maybe the mish-mash of values in the stock ecu will be good enough

 

well.... what's "too lean"? When I get around to doing some actual WBO2 tuning, I plan to get my AFR close to 12.xx:1 Which is super lean if you're running a turbo- because you could run into some turbo-induced lean spots that would be very bad. But with NA, you should be able to get pretty consistent AFR values.... right?

FWIW I have a buddy who had 10.5:1 CR pistons installed this summer in his 02 ES and he hasn't had any reported issues, and he doesn't have any fuel management. He also had his stock cam ground, and the head shimmed to take advantage of a slightly more aggressive grind at the same time. he hasn't claimed any problems.

 

What about a camshaft? Would camshaft free up enough fuel to regulate AFR for our pistons???
I think the best way is to get that wideband afr gauge.

 

^no. most likely it would just make matters worse. the camshaft opens and closes the valves, it doesnt control fuel. and a wideband afr gauge doesnt change anything it jsut reads the afr.

 

^ wideband will tell you if you are lean or rich or stock and based on that you can start tunning. Thx for the info about the camshaft, I thought it was supposed to allow more air and fuel into the engine.

 

I am surmising that this could be a situation. Prolly a few solutions. We never misled anyone. Piggy guys will have option. Everyone will have slightly different mods. We try to make it idiot proof but we cannot account for all the variations. Cams..... Maybe we will sell Piggy with software and then it will be up to you to get it tuned to your specific needs. I will have to ponder it. Regardless, fuel rail and regulator will be cheap fix to keep it safe, although maybe not ideally tuned.

could I please have an explanation as to what being to lean can do to your car?

 

To cut the install cost down by more than 50% comparing to most general mechanic shops (they don't want to do it. this is the reason why they charge you an arm and leg to discourage you), you must find a local DSM shop or DSM'er who is a gearhead.

W/ a service manual, they have enough experience doing the t-belt, pulling the motor apart, and other stuff . . . there is a reason why the mantra of "making mechanics out of us since 89" sticks to DSM'ers. There isn't enough toasted lancers on the road comparing to the slew of toasted DSMs.

 

where would it be easy to find local DSM'ers in my area?
