How much is a 997s engine and electronics? As far as brakes, i would do pads and brake fluid, which seems to be very effective on the forum it seems?

Yeah, unless you're doing some serious tracking of the car (i.e. full cage), good fluid and pads should be plenty. I really don't see how it's possible to overwork Big Reds on the street with good pads as long as you're driving at least a little responsibly.

Softronic would have the program to update your dme for the conversion for around 1300. Engines its seems lately are harder to find because so many have done the conversion allready they used to be around 10k last one I found was around 15k you have to shop around. this is what I want to do to my car but I dont have the time right now. Another choice is to turbo, it's relatavely safe because they are running only 5 psi boost but make around 365RWHP , currently I'm working on a kit for around 6500 it's still in the funding phase.
good luck, keep us posted.

My LN sleeved 3.8 hauls &@*, and should be plenty more reliable than a stock M97 3.8, and makes more power.

If you start with a 3.6 you do not need injectors.

I am currently running RoW 3.6 X51 software, but am planning a tune, probably by EPL in the spring. Over the winter, the car may be getting solid lifters and "race" cams.

I would NOT go the turbo route on anything but a built engine.

Yeah, I thinking a built block is better than an engine swap at the moment, but I am not sure. Look forward to hearing your input.

OP: Are you part of this class action?

N54 Class Action

The fuel pump issue is well known by now. That's the only thing keeping me from buying a 335i as my daily driver.

Nah, I have a lawyer filing a federal lawsuit for breach of contract because of not honoring their warranty. Its similar to most lemon laws, but it has some advantages. I have a "software fix" for my hpfp. They said it would fix it but all it does is run the lpfp more to supplement the failing hpfp...

Flat6 engineering, I am very interested in this option. IS it feasible to have a 4 liter daily driven? Also, I would guess that the car would be a late model 986s because the block is different?

I'm not too picky on the car as long as its in good condition. Basically it would have to be a black or tan interior, have litronic headlights, and hopefully the bose sound. I like most colors except the burgandy and some off the rare colors.

If you could pm me some information on the rebuild it would be greatly appreciated.

rcracer_tx,

The 4 liter is not an engine that I have developed for street use, because it more than likely would not pass any emissions test and I'd rather not get into a situation where their is even a chance of that occurring. This is why an engine like this is sold to be utilized on the track.
