help - turbo eta

[matty.dc]

I have th3 3.73 diff and I like it. 4.10 would be to short but I think the 3.73 is just right.

If your just driving around town 4.10 picks up nice. 3.73 is perfect for daily around town and on the highway.

But 4.10 is perfect on small tracks like TMP if thats what your going for.

Just beware.... when I'm rolling 100KPH, I'm sitting at a shade below 3K RPM in 5th with my 3.73. I love it because lots of torque and short gears is fun, but with that ETA motor, it might get a little tiring pretty quick (especially on the highway).

[adam325i]

Oh your right Karmatose. Forgot it was an eta. Drop that boat anchor and get something decent in there. Slap that I head on and go to town with turbo. M20 are pretty easy to come by.

If I were you, I would build the 2.8 stroker m20.
Go through bullet ride's threads. You will soak in some really good info. Also it will give you a really good idea of what you will be dealing with.
This is his 2.8 build

That should keep you busy for now. There are many more threads out there I just can't remember all of them and I only have a few saved on my phone. If you do your homework and ask detailed/specific questions ppl will help you. There are a few really knowledgable ppl on this site, bullet ride, Denny, notorious VR, e30 kid and so on.

Good luck!

As much as I'd like to toot my own horn, unless you have access to a machine shop, or know someone who can hook you up with a really good deal on machining I wouldn't recommend building a 2.8L M20 because in terms of performance/$ at the end of the day you'll be left disappointed compared to a turbo or S52 swap. As I pointed out in this thread...

This whole set-up probably sold for what my 2.8 build will end up costing me (not including my own time and labour) and unlike my build it's a proven, turn key set-up making double the power. If you had to pay a shop to machine the crank, lighten your flywheel, and machine your pistons, the cost of building a 2.8L M20 would rival the cost of doing a turbo build or an S52 swap.

That being said it's still worth it to take a look through my build thread to get an idea of what's involved with building a motor up if that's something you're interested in doing. I took on that project with the intent of learning a thing or two about building a motor so for me the lower performance/$ invested is offset by the knowledge and experience I've been gaining.

damn guys thanks alot for all the info u guys gave me more help than u think and i really did miss out on some nice deals. i shouldve made a max account alot earlier. well now iam looking for a complete i motor and iam just gonna boost that and i finally got my 3.73 lsd diff thanks to bimmerboys , really nice guy. i kinda gave up on that eta motor, i wasnt gonna go for an eta in the first place but the body and the kms where unreal for the price so i had to take it lol. but iam on the look now for a m20b25 so do u guys think a reasonable price would be for a complete swap and would my eta tranny work on it ?

[karmatose]

Not sure on a reasonable price for an M20B25, but your ETA transmission will bolt right up. Here's some great info about the differences between the G260s: http://www.r3vlimited.com/board/showthread.php?t=215361

Another thing you'll need to consider when swapping the motor is cooling. If you get a motor from an 88+ (which I recommend. The 885 head is the way to go) the rad hose configuration is much different. You can swap out the newer style water pump for the older style and keep your current cooling setup or you can swap to the 88+ cooling setup which requires all new hoses, a different rad and a different overflow bottle.

When I put the motor in my car, I did the swap to the newer cooling layout because it leaves the door open for awesome and inexpensive aluminium rads (Mishimoto, PWR, GSP... I went with the GSP rad.). If you were going to replace the coolant hoses anyway, swap to the late model cooling and get yourself a nice aluminium rad.
