DeLorean isn't that what I jusat said?
05-16-2005 12:40 PM
mike saunders From model year 1993 to MY 2002, Saab "Ecopower" engines were the ones based on the Triumph/Lotus block. They came in all configurations: n/a, LPT and FPT. They were also 2.0L and 2.3L (The difference is the length of the connecting rods) These are the B235 series (Viggen and 9-5 Aero), B205 (00-02 9-3 SE), the B204 (NG900), and I think the B202...

The 9-3 SS uses the newer Ecotec block, shared among Grand Ams, Malibus, etc.
05-16-2005 10:14 AM
DeLorean that's because the "ecotec" is a GM engine, the "ecopower" is just your regular triumph derived 2.3 liter Saab I4 engine, it's of no relation to the ecotec engine.
05-16-2005 08:37 AM
mike saunders I thought the "Ecopower" engines were the predecessors of the Ecotec.

Ecopower is very, very much a full-pressure turbo. My B205R from an 01 9-3 SE is an Ecopower engine. I'm not sure about the B235R in the 9-5 Aero. (Anyone have an engine pic?)

Over at ecotecpower.com there are guys trying to scope out Saab turbos to use in their engines....
05-16-2005 06:26 AM
DeLorean wait wait wait, what am I thinking the NEW ecotec is a completely new engine in the new 93's it has NO relation to the old triumph bases 2.0 2.1 2.3's that saab has been using since the 60's, and still uses in the 95's.

the ecotec comes in cavaliers, new 93's and saturns in 2.0 or 2.2 liters. yes there is a supercharger kit for it HOWEVER, the saab 2.0 version already has a turbo, which can be pushed a lot more than that little Eaton supercharger which is primarily meant to be sold as an upgrade for cavaliers / saturns.

the reason I got mixed up was because the newer saabs used a pet name for the LPT engines "ecopower" which means baically nothing...

DeLorean light pressure turbo
05-16-2005 06:16 AM
ng900 Forgive my ignorance, but what does LTP stand for?
05-16-2005 06:14 AM
DeLorean same block, but I'm pretty sure all ecotec engines were at least LTP, and T7.
05-16-2005 06:05 AM
ng900 Supposedly there's one around somewhere that will actually give 80 more horse, a real belt driven supercharger, and I think the price on it was like $2000. I can't find it anywhere though, my buddy saw it in a racing magazine, but couldn't remember which one, and by the time I got to look for it, the next month's issue was out. He said it was for the 2.3 ecotech engine, which I think is the same engine that's in my car. If I'm wrong, someone please correct me.
05-15-2005 09:22 PM
PureNordicPower The only worthy superchargers i find onlien cost more then half of my car. Not happening.
04-15-2005 07:57 AM
ng900 Hey, check out this thread to see the pics of the switch I mounted for the supercharger.

There we go. I want to enhance what I already have, and not have to spend thousands to convert it to a turbo to get a measly 50 hp...I am looking into everything right now...Custom mapping etc...We'll see what happens...It's all dependent on cost also...I am not rich
kind sounds like an "Ensight" commercial....had to laugh a little, just pictured this silly grin

But wish you success..
04-14-2005 06:17 AM
stevehayes01 I agree with the need for speed but I also can appreciate all cars for one reason or another. Oh well I guess the N/A guys will always get teased and the turbo guys will always brag about boost...
04-13-2005 06:32 PM
BurnsSide42 stevehayes01 - you need to know that DeLorean's opinion about a car is - if it's not fast - why drive it. He hasn't realized that everyone doesn't need to do 130mph+ and get there in 13 seconds or less.... The fact that most people on the road today driving in their Fords or Honda's have enough power they can't handle is just another issue I'm sure he realizes, just isn't considering. Yeah - the n/a are slower - but still swifter then some n/a cars on the road. Atleast a Saab will always have comfort on their side - not all cheap and plastic like, as most GM's are today.... but Saab owners pay for that luxuary.
04-13-2005 05:27 PM
DeLorean but you see, nitrous power doesnt count! you could do that on a turbo and get the extra 50 HP in addition to the 185 HP you already have stock

sure, you would be picking transmission parts off the ground after a few too many of those, but it would be good fun while it lasted...
04-13-2005 04:52 PM
stevehayes01 Delorean ---- I have driven an N/A NG900 and yeah it is slow but not really any slower than any other N/A 4cylinder is. Hech driving my 9-3 on base boost is slow for that matter.

To get 50Hp out of the N/A you would only need to spend the $500 on a Nitrous Xpress Kit with a 50shot jet and install it with a RRFPR. It is done on N/A cars all the time I am just not sure why people don't do it to SAAB's other than the N/A is just no that common. Who knows but hey if they want to stay N/A then more power to them.
04-13-2005 04:47 PM
DeLorean if you drove a turbo, you would undertand why people rip on the n/a all the time.

it's cause they are SLOW!

well the point is that in order to get that "measly 50 hp" (wich of course youre forgetting the torque) out of your n/a engine you'd have to literally spend thousands, whereas a turbo would cost a whole lot less than that.

but hey, do what you want.

probably because saab did a much much better job at it themselves!



if you want power, buy a turbo, if you want economy and youre an old woman...buy a non turbo, its that damn simple!

My thought would be to dump the entire engine control system and go with a stand alone engine management system for the car. A costly investment but for a gear head that likes to get into their car why not? Sure SAAB did a better job of it by building the turbo model but your missing the point these guys don't want to give up the ghost and sell off the N/A's they want to enhance what they have already.
