    Bunch of e questions...

    I tried seaching, but there's just too many posts to pour through, and I'm exhausted.

    1. I have access to an I manifold and TB with injectors. Should I put it on? I'll lose some low end but I'm at like what, 190 or something with a chip? I think the high end gain is worth the sacrifice. Anyone else done this? Do the I injectors flow better? I know the TB is 10 mm bigger, so that's a no brainer. Do I have to port match the head to the i intake to get the benefits? Anything else I need, or will it all slap together? There any sealant I should use or just the stock gaskets?

    2. This chip. Love it to death, never driving an unchipped car again. I have a JC chip. My redline is now...what, 6k? Can I just toss the i tach in? I think I read I could, just making sure. It'd be nice to see what's going on :) Or a super eta tach?

    3. ES and IS springs are the same, yes?

    your redline is roughly 6200, you can toss the tach in, just be sure you change the coding plug too.

    i think the es springs are a bit stiffer, i could be mistaken though.

      1.) There is a fitment issue with the 325i manifold to the 325e head and I'm not sure how it's resolved. The 325i injectors do flow better but have a different impedence and aren't compatible with Motronic 1.0.

      2.) Redline is 5200. You can use the 325i tach if your car is built after ~1/86 or so and uses a coding chip. If built before, use an 84-85 318i tach with a coding plug. Keep your original coding plug/chip.

      3.) 325i valve springs are dual coil, 325e springs are single coil.

        Mr. ETA himself :) Anyone know about the i intake mani fitment? I know there are enough of you out there that have done it.

        Forgot about the impedance on the injectors, thanks for that reminder, Fred.

        Redline with the JC chip is 5200? I thought it was higher for some reason.

        My car is an 86 ES, I'm fairly certain the build date was after 1/86, but I'll check to make sure. If it is, where is the coding chip that I'll need to swap out?

        And for springs, I meant the suspension, that was my fault :)

        Thanks for the help Fred.

            Whoops, dunno why I thought you were referring to valve springs. My fault. But the suspension between the two cars are identical.

            The redline with the JC chip is 5200 and the needle should just bump off past the 5k mark. If you have a coding chip, the easy way to tell is the color of the instrument cluster, blue back almost always means chip, white back is a plug. The chip is located on the lower right of the cluster, beneath the tach and water temp gauges. You don't have to actually swap the chip, but just keep the one you have in the car now.

            It's nice to have the extra numbers on the 325i tachometer, but with the eta tach passengers were always impressed when I revved the car past 5000. :D

              Really? Whenever I have passengers they see that the tach only goes to 5000 and just laugh...

                Perhaps the fitting of the intake is the problem of mounting cold start valve, vacuum lines, ICV, and such. Otherwise it should go right on. The i throttle body works fine on the eta intake with a port match. I noticed gains from doing this, not much but a little quicker, better throttle response. You have to get some goodies like intake boot, breather hose, and you may have to block some of the ports on the tb depending on what intake you use.

                With your mods and i intake and tb you may be getting around 150ish horsepower which isnt too bad at all. Some things that will make you go a little faster; single mass flywheel, 3.25 diff, and a 325i exhaust. Some insurance would be dual valve springs and slight port work to the head (to help flow at higher rpms). Ive got some H.O. eta plans in the works, I will inform the greater eta community on the secret when it gets completed.

                  So.. someone is giving me a i cluster for free. My car is an 85 (so probably 84 build?) what should I do to make it work right.

                  Sold it.

                    is his hp really 190?..... just with the chip?.... wow hmmm btw, which performance fly wheel do you guys recommend if anyone has replaced it? ... and how about clutch ?....

                    Basically building my Eta into a sleepr....really hard right now after i focused all my money onto my business.

                        Hello all,
                        A few questions, i have an eta, only ownded it for a month or 2 now and have been trying to learn as much about it as i can, so far what i know: Running 3:25lsd, e21 323i head, pod, and have 'i' tacho not sure from what model,
                        anyways has a white back whatever that means.

                        Have no idea what is going on inside my engine but after taking to a bmw mechanic and letting him test drive it was told that my limiter is at around 7,500/8,000rpm (obviouslycant read cause tacho stops at 7). Anyways i dont drive it that hard to around 5500 max, so with this head will that mean i have had any engine work done?? valves, intake manifold(still have eta valve control gear on intake manifold), pistons??? If anyone could help me in any way would be very much appreciatled whilst we are on the topic of ETAS!!

                        Hope i havn't stolen the tread!
                        BTW If anyone has done the 323i head conv please pm me!!!!!
                        Cheers, Mark
                        Da Breeze....Can you feel it?

                          either port-match the eta head, or get a 731 head off a euro 323i (or 320i if you're going to upgrade the cam).

                            Nah, this was a free only mod, since it's just hanging out in the garage. M50 over the winter....this us just my beater. I thought it slapped on there, my bad.

                              The flywheel to find is a single mass from a pre 86 build date eta. Some of you may already have one. All others have a dual mass around 28~ lbs. The single is under 14 or so. You can have this lightened as well. The only thing is that you need to have the proper clutch from a pre 86 as well (throw out bearing, pressure plate). From what I hear it is well worth it.
