turbo in an Eta?

[Digitalwave]

Better pick your turbo wisely or you will only be making full boost for 1,500 RPM :)

[Rob]

yeah you'd need a fairly small turbo to even get boost

[JPbmw]

would a garret t28 do the trick?

well anyways i think im gonna swap engines first, now i have to decide between swaping in a m20b25 or a m30; i know the m30 is stronger and has more power to begin with but it also needs more modifications, so i dont know what to do :?

btw: Thanks Kansas-ix for the link!

I was thinking

for the 2.7i, when you slap the 2.5 head on the 2.7 block, it has crazy low compression, right?

so why not just keep the 2.7 pistons in there, so it has the low ass compression, and turbocharge it?

ok, ok!

Enough already. A turbo would work excellent on an eta. Start here then Google for more info: http://www.sterling-carcare.com/Perf.../dinan-m3.html . Anyway, the first thing you should do is read "Maximum Boost by Corky Bell". I can't stress that enough. After that, decide how much power you want to put to the ground and how you're going to drive your car; track, street, etc. The hardest part of the whole project is going to be tuning it to the powerband. It doesn't matter that your redline is that low, most commercial turbo diesels are rev limited lower the a stock eta and they produce tons o' power. With the proper tuning and compression, you should be able to run ~10psi which should equal ~100 extra horses with matching torque. Most people seem to think that eta's are useless, low-revving, grocery getters and the all they want to do is change motors. For what? An extra 50HP, at the crank. :roll:

Seriously though, the planning for this is going to take much longer than the actual build but when you're done you'll have a motor that will scare people into believing in eta's. I'm in the planning stage on mine and collecting parts that will be needed. It isn't going to be cheap, but it shouldn't be anymore than a stroker build or M50/52 swap unless I go with a kit. What's the fun in that?

This is all my opinion and admittedly, I'm not an engine builder. I am working with one for this project. It also helps that he builds and races turbo bikes and is finishing a 240SX that will have a twin turbo 5.0l stuffed in it; scary fast. :shock:

and Finally, the point: done correctly, you'll make as much power as you want and it will still be an eta motor, still be driveable and still a hell of alot of fun to drive.

50 hp for $500 is a pretty good deal if you ask me.

im swaping out my eta for the i....my boys mechanic did a engine replace on a 89 325i the engine was somehow broken so im telling him to tkeep it and im gonna through it on a jack stand and work it rebuild it and run a 2.5 turbo with forged pistons/rods and all that fun stuff....im gonna get him to get the parts and do the work....since the engine is sitting there ill get it for nothing probably like 50-100 bucks....then im gonna get the full engine back exahust for 300 for the i....then i will be set and ready for my turbo once my finances and work is done....im not looking at spending more than 4k to have the engine droped in and turboed...im hoping for 250+ hp to the wheels....since im not planing on doing stock internals i should be well past the 250 mark.....and i want it to still be reliable as a daily driver....you think this senario will work?

more of the same...

DWave: Where can you find a complete "i" long block w/ ECU, wire harness, and oil cooler for $500. I haven't even seen anything like that on ebay in the recent past. You could get hooked up with an M30 setup for that price, but that's not the point. For those kind of gains and price, I'd rather just use a JC chip, free flow exhaust, and CAI w/ heatshield. That should put me really close to that extra 50HP plus it bumps my torque close to the 200lbs mark. Change your gearing around a little and you'll be even quicker than a stock "i/ is". But hey, I'm not busting on you here and we've wandered off topic.

next: PatNY~ 250rwhp should be attainable easily with what you're starting with. Hopefully, that engine isn't too bad and a rebuild fixs the problems. As for the exhaust, you don't necessarily need one from an "i". You're not going to have an "i" exhaust manifold on the motor after it's turboed so save your cash and spend it towards engine management. You could probably even use your eta exhaust depending on the down tube from your adapter/ turbo manifold. Which adapter/ manifold are you going with? I've been looking at both the ProTurbo adapter and manifold: http://www.proturbo.fi/index_en.htm . Either one should work fine, I'm just unsure which one would fit best in my engine bay.

50hp from an intake, chip, and exhaust... lol thats a good one.

Also, eta exhausts are tiny. Turbos need to breathe, I would think a full custom exhaust should be a requirement for an FI car, especially an eta.

It will maybe work with an 524td/324td turbo and manifolds ??? that are low rev engines too :roll:

$500 for a full m20b25 engine swap?....i dont think so either

Click the link dude.

Yea and thats just for the engine, add shipping, ECU, and all the other extra things you need, like exhaust. and thats if you do all the work yourself.
