Well just to clear up some facts:
The SD4 is still in use today. It is the authorized engine for the ARCA racing circuit. As well as many race boat classes.
Kansas Racing Products bought the rights to continue to supply the SD4 engines. The Original GM SD4 heads are not used due to the expense. They now use Chevy 2.02 heads or Ford SVO heads. (can be machined for Mopar heads too) KRP even made updates to the block and sells parts to completed engines.

http://www.kansasracingproducts.com/history.html

The Ecotec is nothing but a re-designed version of the QUAD4 which is almost as old as the SD4. (Pontiac designed/built the SD4, and Oldsmobile designed/built the QUAD4)

The Ecotec requires forced induction to match the horsepower and torque of a normally aspirated SD4.
The ARCA specs have the 2.7L SD4's pushing 275-280hp normally aspirated. For $8500 KRP will sell you a "streetable" 230hp 2.7L SD4 or for $800 more You can get it stroked to 3.0L and have 250hp. These are normally aspirated and very strong engines. Add forced induction and you can hit 350hp easily.

(I know costs because I was actually looking at buying one. I have 2 "build sheets" from them)


My point is don't berate an engine you don't know about.


Actually... New gen Ecotecs in the upcoming 9-3 coupe makes 238hp N/a and be the second most powerful 4cyl available. they are also coming out with a 280hp Turbo version and a 300/340 v6... Stuff you probably haven't heard of becasue it hasn't officially been announced. I know GM has a few test mules running around of the 238hp N/A car in the 9-3 Aero . The Architecture of the Quad 4 and the Ecotec are quite different actually... But hey I this is only what I have been told by the head of GM powertrain when we were doing training on new product in michigan...

You will see the 238hp N/a Cars later this year..

You do know that all SAAB engines are turbo'd right? It's their trademark, Sort of like Suburu and all-wheel drive. They are not going to use a normally aspirated engine in a SAAB.
Per GM's Powertrain website "they have experimented with a 2.0L turbo at got 238hp, the 2.2L turbo is being tested at 280hp" .
Right now the 2.2L with 10:1 compression is 140hp normally aspirated.

stop
i drive a stock ;-) 4cyl fiero everyday with a N/A 141 Hp at the rear wheels.
everyone belives this to be imposiable it's not you just have to start from the crank up. i have meny posts on the PFF out lining everything that was done sorry i dont have the time today to type it all down agian. but FYI i have put 23000 KM on the engine since aug 2nd 2003 and have had zero problems with it runs like a top. thing i have noticed however are the power band sucks 3300 rpms. my trany is starting to hate the extra power (isuzu 5 speed) and with the cam profile it has is lode at 950 rpm. my question is why? the duke is not worth the money i have spent the money and would never do it agian. i will give you my 4 cyl for a 3800 or 4.9 in a second. sorry i had to give a drivers input.

Dyno Slips for that 141 RWHp...

Better not photoshop them like you did that sig...

I just don't get it , we see a thread about a dyno day where a 3.4 that has a mild build puts down 135rwhp..and people expect us to belive these weiner mods to the 2.5 will yield more hp..

then people get bent out of shape..it's just logic..


Oreif: I saw that car int he mall , now thats badass!

Look at his sig, He has it bored/stroked to a 3.0L. I think he did a lot more than just a few bolt-on parts. Sounds like he started from a basic block and built it up.

If I had the $7500, I'd but the Pace car and the SD4 Today!

Its me I just cant for some reason post with my other name so I had to change it up. I have decided cause one that you all seem against it, and two a differant engine may have just become available to me, to go with a 3800 and just for go the 4 cylinder all togather. I like the 4 cylinder for its fuel efficency. but if you all insist then fine I will dump the engine. However if you ever want a car to gain value then a modified version isnt it. Most cars that go for high value are those that are bone stock. That is why I want to go with Just modifing the 4 cylinder, However I will not dump the engine in a yard but tear it apart and rebuild it, and put it in a crate for safe keeping.
Besides with my Grandfather owning about 4 Buicks with the 3800 and knowing how much of a proven engine that it is and how reliable it has been to us, I think by far it is the best engine to choose. It is by far GM's best engine in my opinion.
