Yea, I have the money for the motor now(payday) but I still gotta pay a mechanic to wire it up for me so I'm gonna hold off another few weeks before I order it. It still going to look like **** when the swap is done because I had to choose between motor and paint, and for now, motor matters. Motor should be in and running by sept- oct. November at the latest. Car should be totally done by 2012

Figured youd be doing all the work yourself, bummer Good luck with the project, im sure these guys will get off your case, eventually.

Sigh, im a dumbass, i totally misread the original paragraph. From the sounds of it, youre not too sure of what is actually going into the actual project, and since you said the mechanic, youre also not doing any of the work yourself. LS1, big and dumb, far from it, wankel, small and brilliant, no comment. The ti, for its size, is fairly heavy, not matter what engine you put in it. In all honesty, for its size, it should weigh in moreso around 2500 with engine installed.

Ive had 4 tis, clubsport, two sports, and an active as well as the m44b19, m42b18, m50b25, and ls1/6. The 4s are very underpowered for the chassis, they at least need 5psi to feel competent in this chassis. The m50b25 is much much more adequate for it and feels amazing when you install the correct suspension. My m50 had quite a few mods but was still no S5x but easily matched up with gt mustangs, r/t chargers, etc. with street tires, 4.10lsd, intake, exhaust, and a chip, fully equipped even.

The ls1 package isnt dumb, big, but not dumb. Its a VERY compact drivetrain, everything except the PS resevoir and pulleys sit on or rearward of the front subframe and the t56 six speed helps put weight where it belongs, at the center and low in the chassis. The driveshaft is custom, and the rest is BMW also with the 4.10lsd from the e30 m3. Easy torque and horsepower from down low all the way to the top, not to mention hp/$ ratio for mods an maintinence is good that its worth the time and effort to install one. Everyone says, OMG, ls1 so stupid in a ti, yet, in europe, guys swap in the real s5x in their tis, which is nearly the same output but with an iron I6 and 6 speed, dont see anyone crapping on them.

To each their own, hope yours turns out the way you want, id personally grab a miata engine or even an old 5.0 mustang engine with a 5 speed.

I am one of the neigh sayers when it comes to the 318ti and the LS1. I can't argue with you Tony about the power compared to the euro S5X but the power band (delivery) and the overall potential of the LSX is what concerns me. I personally wouldn't bother with putting anything more than 350 hp in the Ti chassis. I have a very strict formula in how I build my cars,
I blend factors such a performance, safety, reliability, aftermarket support and a few other things to create a overall balanced vehicle.

Notice I never said that I didn't like the overall idea of the LS1 swap
I would just rather have it in a different chassis with a huge contact patch 305s all round:










Maybe the OP isn't a troll but I'm sure that some of his statements are exaggerated. Here is my thoughts on the aforementioned swaps.

13BTT: Heavy, expensive to maintain and modify. Power potential 350 reliable HP. I know you can show me 650 hp versions but those engines lives are measured by hours and cost $30k to build including all the aux components to support it (fuel management, turbo upgrade, etc). Apex seals exit at the first sign of detonation and not many people really know how to build these engines anymore.

SR20DET: A friend and I imported and installed these back in 2003 when I had a shop in Cali. Great little engine with awesome aftermarket support and low cost. The problem is the power potential is less than the S52 for overall cost. Dollar for dollar an S52 will cost much less and can make just as much power (if not more ) than the SR20det. Read 400 hp sr20det will cost you around 7k which you can do for around 5-6 with a S52. Stock for stock a S52 will beat the snot of a SR20det every day of the week. Blacktops with T28s @ 9 psi put down around 212 Hp and 209 ft/lbs Tq.

305 on all four corners....doesnt exactly sound like it was meant for daily driving. As far as putting wide patches down, its very easy to put a decent amount of meat under stock ti fenders, i already have them. As far as sticking a 305 under a non-ti and non-z3m, thats some hefty modifying just to get them under the rear then what about scrub raidius, offset, rim size, camber specs, etc. 305s are just overkill, even on the track for an e36.

Im not here to argue with you big D, so im going to drop the subject all together, good luck to all of you with your projects and be safe.

This is a discussion and I welcome any and all thoughts on the matter. This car will be more of time attack car. I'm adding e46 fenders at all four corners and lookng to put about 425-475 whp. I won't go any lower than 285 and I don't see how this can be an overkill. What size are you running. I have 255 all round on the Ti and it's just about perfect. Steering response is a bit slow but I have tons f grip.

The guy that builds race engines for the shop I play at, was proposing building a LS1 made to run on E100. Compression over 14:1 and would pull something over 800 NA HP.

Now really how much trouble could a guy get into with that.... LOL

I understand what needs to be done, and i am doing most of the work myself, but like many have said, this has never been done before, it would be good to have a professional do the complicated part of making the car functional i.e wiring the gauges, power windows, stereo. its not exatly a simple swap trying to make a BMW and Mazda play nice. Ive been looking wiring diagrams and honestly, they might as well be in japaneese. uncharted waters dude, im sure i could figure it out, but id rather not risk it

BMW uses a standalone engine harness, interior is all on it's own. Cluster isn't hard to figure out, most people wire in gauges, just because it's not on the forum, does not mean it hasn't been done before. If you're not comfortable doing wiring that's cool, it's not for everyone, but it's not difficult either.

There are guys using Motec or other standalone systems to put the rotary in other cars, its a Bi$$$ to get working right.

I raced a rotary NA in a rx3 in ITA for a couple years. Reliable at ITA build limits but ate too much fuel for the HP and was loud.

Normally you isolate the wiring harness between engine/cluster and then the rest of the car. The pain is the little computer boxes that run the accessories like the headlights, dome lights etc.

If I was tangling with this I'd gut the cars wiring and wire the chassis form scratch to get rid of all the silly ladder logic BMW uses to control stuff.

Painless wiring harness for a hotrod to replace all the BMW wiring for lights heat and such.

just a thought..

Dave

Its not just on the forums, its on the the internet in general. The only thing i can see even remotely close to this swap after exhaustive searches is a rotary in a z4. to my knowledge, and to the knowledge of pretty much everybody i know and have talked to, this hasnt been done. I know how the wiring works, but the interior wiring socket is tough to figure out for me and needs delicate expertise to manually wire.

also found an e30 316 with a similar swap
