---------------------------------------------------------------------- Date: Wed, 5 Apr 2006 10:13:01 -0400 From: "Dawes, Chet " <[EMAIL PROTECTED]> To: <[email protected]> Subject: Re: Tires for E46 Message-ID: <[EMAIL PROTECTED]> Tammer, So much for heavy cars only! ;-) My old 318ti was not 'heavy'. At sub-2800lbs most would consider it a pretty light street car these days. Besides, the question is for an e46 which is certainly well over 3000 lbs in any street trim. For sake of full disclosure I ran a 215/45-17 size. My experience with the Yoko ES100's was miserable. Those tires made more noise than anything I've ever experienced, even worn wheel bearings! I tossed them with considerable life left but they were NOT long wearing tires either. Horrid cool/cold weather (yet dry) performance and I'd say poor wet weather performance. On the track in the dry, they were reasonable at best and based on my street experience with them was a complete surprise to me. I was so excited to wear them down. I've never been happier to spend the $700 on new tires. Since then I've run the Michelin PS2 which has spoiled me beyond belief. The best street tire I've ever driven-period. Superior to my formerly favorite S0-3's in every category. I've run them wet (including serious downpours) and dry at the track and on the street and I have been thrilled with them. Pricey, but you get what you pay for. Silent, good wear, phenomenal grip wet, dry, standing water, etc regardless of ambient temps. The BFG g-force sport would be my next low-cost experiment provided I can pry myself from the PS2's to try something new. A good friend has a set on his P-car but has not put enough miles on it to get a very worthwhile review.

It seems that most of the complaints come from drivers of heavy cars. They do get loud, but I'm willing to live with that. I'm not in a position to pay more than 2x as much money for 5% better performance and 5% longer life. I have been shopping for a set for the E28 M5, and due to its weight increase over the 535 I am looking for something other than the Yoks ... I'll search for deals on the T1-S, good call. -tammer **************************************************************************************** Note: If the reader of this message is not the intended recipient, or an employee or agent responsible for delivering this message to the intended recipient, you are hereby notified that any dissemination, distribution or copying of this communication is strictly prohibited.

Wider, lighter and better gearing for the same basic money. :) Check out the One-Lap-O-America results from last year if you want to see wet vs. dry high end tires. Same cars, same drivers, same tires on the wet and dry skid pads at tirerack. Oh and another negative impression I had with the Yoko ES100s. Extreme TRAMLINING. Same alignment, same car, different tires (PS2 and S0-3) had zero.

To get the cartridge out, slide a business card underneath it, in the centre. It will trigger the release. If a disc is out of the cartridge, it will remain in the changer and you will have to dismantle the changer to get it out.

I have not really found anything in the archives, which I find hard to believe, but non the less, I am confused about a few things, or rather ignorant. What of the fuel system? Does it need to be swaped as well. I have an 87 so it is the early Motronic, not the super eta system that was in the "i" motor (Motronic 1.1 I think). I assume the ECU has to be swapped, but what about the electrical? How much is plug and play, and how much needs to be reworked? I already have a 3.73 lsd. Also I know the exhaust will have to be changed, but is it the whole system, or just the muffler? Any responses to any of these would be appreciated, or a link to information, or refrence to archived material I missed in my remedial search.

I have not really found anything in the archives, >which I find hard to believe, but non the less, I am confused about a few >things, or rather ignorant. No good write-up, but as the owner and mechanic of an M20B25 engine I might be able to answer a few questions. >What of the fuel system? Does it need to be swaped as well. I don't think so. From what I have read in the various manuals and looking at the parts lists, I think the fuel system can be left alone. While the B25 engine does use a higher fuel rail pressure than the B27 (4.5 Bar vs 4 Bar), the fuel pressure regulator is on the rail itself and should be coming with the engine. The fuel pump should be capable of over 80psi anyway, so there should be no problem there. There was only one test procedure in the book for all the M10/M20 engines in the E30s. >I have an 87 so it is the early Motronic, not the super eta system that was >in the "i" motor (Motronic 1.1 I think). Ok, a little lost here... which is the '87? The B25 engine or the chassis it is going into? From what I understand the Super-Eta engine ('88 only?) was special. The B27 engines otherwise used the Motronic 1.1. The B25 engines started with Motronic 1.1 and then moved to Motronic 1.3 in '88 when they stopped making the B27 engines. I think. >I assume the ECU has to be swapped, but I would move the ECU with the engine. Although a B25 might run with a B27 ECU, the tables and curves will be wrong for the engine. Performance and emissions will no doubt suffer. >what about the electrical? How much is plug and play, and how much needs >to be reworked? I believe that the engine has a harness all to itself. The wiring on the engine should move with the engine. There should be a harness for the ECU that plugs into the engine, (big connector in the middle of the firewall, I think) crosses the firewall, plugs into the ECU and a few other bits inside the car. I believe the wiring is the same for both Motronic 1.1 and 1.3, so you might be able to just use the harness in the car and swap the engine and ECU. >I already have a 3.73 lsd. Also I know the exhaust will >have to be changed, but is it the whole system, or just the muffler? Whole system, I think... The B25 uses twin pipes from the manifold back. The B27 Was twin pipe into the catalyst (or crossover pipe at least) and then single pipe back. Given that both engines used the same manifolds on the same block on the same chassis, you might be able to run with the old eta exhaust. It will be a bit restrictive, but if you are looking to get on the road again fast, that might be the answer. You can swap the exhaust out later. The O2 sensor will have to change, but they should be compatible at the threads, so no problem there. >Any responses to any of these would be appreciated, or a link to information, >or refrence to archived material I missed in my remedial search. >Ryan- I believe the only real differences in the engines were: Speed and pulse sensors (B27, on flywheel) vs. crank position sensor (B25, on crank pulley). Different fuel rail pressures (4.5 Bar for the B25 vs. 4.0 Bar for the B27) Different fuel injector resistances (14 Ohm on the B25 vs. 2 Ohm on the B27) Different placement of the idle valve. The B25 engine doesn't have a cold start injector or the thermo/time switch. The B25 engine has the oil filter/cooler adapter on the block where the filter just screws on the B27 block... and the oil cooler up front. The B25 has a sensor for the #6 plug wire to get the injectors in the right order. Of this stuff, the only thing that might be a problem is the oil cooler adapter, but even that should be simple enough to move over or ignore by mounting the filter on the block just like the B27 engine. Of course, this is all theory... -- Joe -- Joseph M.

I thought the early ETA had just the Motronic system and the later "Super ETA" had the motronic 1.1 like the B25. I have an 87 325e with the early system. After thinking about it for a while I might just buy an E30 325i. The only reason I considered the swap is that the body and paint on my car is in good condition, and i have already put enough money into suspension, brakes, wheels and tires, (which can be transfered as well as the "is" leather seats I have)so why not just keep it? Besides a new car means new problems, but at any rate thanks for the info.

They are 3 Bar for the B25 and 2.5 Bar for the B27 engine. You seem to be right about the ECU issue. Eta engines were plain Motronic (35 pin connector) while the "i" engines were Motronic 1.1 (55 pin connector). The exception is the '88 Eta engine which got Motronic 1.1. An engine swap might still be a good idea. You need the engine, the ECU, and the engine harness. The engine harness on the B25 includes the auxiliary relay block, the connections to the ECU, the OBC, and it all plugs in through the Main Harness Connector at the firewall. That connector is the same on '86 and later E30s (physically if not electrically). If the body, paint, suspension, seats, dash, electricals, and so on are all good on your car it might make more sense to do the engine swap rather than buy an "i" and have to swap everything else over or start over with the replacement of suspension parts. -- Joe -- Joseph M.
