ecotec swap (Page 21/98)

As I see it, the ecotec will go much farther than the 3800 series motors. Granted stock for stock probably not, unless they get pushed in corners then I think the weight difference will really shine. With the torque not as low as it is with the bigger motors the trannys should hold up more, also. I can say this With all the weight of the ecotec in the back of my fiero it has a nice front rake that was not there when i had the 3800 in there.

I think we should start a revolution!
Wooo Ecotec for the win!!!

All you have to do is look at the GM drag racing team to know that the Eco is capable of incredible power. Looking at the GM build book makes it even easier to see that they will become more popular. Wonder how long it will take for someone to have a "kit" to make it more accessible by the average owner?

Honestly, with the help of the other ecotec guys here, I'd like to eventually attempt a few different kit levels, or at least offer a parts list of what you should get for the swap.

Well that was my plan (Plug in play ECM), but there wasnt much of an interest, once I get my spacer made and start the motor I will go from there.

The issue at hand, at this point, is getting any of the newer VVT ecotecs to work well with a (relatively) easy-to-do kit. I think the majority of my time working on the Fiero will be R&D rather than actual design.

Curious why you went with such a small turbo as the TD04 13T (WRX turbo). It will spool pretty quick but it cant hold boost well and has been known to boost creep. You could send it to Jerry at www.boostplanet.com to get his monster port. That would help alot.
Anyway, nice progress. Glad to see its coming along. What are you using to trigger the meth injection and is it progressive? If not, look into SMC enterprises progressive controller. I used it on my old 420hp WRX with great results.

actually the turbo choice was based on this :it originally was designed to feed a 2.0 litre motor ,mines a 2.2 ,not much difference in size ,and it looked easy to install .not much science involved there .this is actually a big 16g from turbochargers .com .it is designed to be an upgrade to a stock WRX .it spools up really quick and what is turbo lag anyway?there is no lag here.
the main drawback doing it the way i have is that you have to use an oil scavenger pump .i have to run it for 20 seconds before and after driving or else i put down a 007 style smoke screen.
the bost system is progressive ,a snow unit with an electronic boost control .you set the start spray and the full pressure spray at boost levels you pick yourself .i start at 3 and full on is 6 .this is a bit excessive until i get my bigger injectors .
i am amazed at how well the stock computer handles everything .it is very civilised to drive when you dont have your foot in it .
and it does handle a lot better .i think between the lighter weight of the motor and the loss of a lot of ancillary devices (the original exhaust system and assorted plumbing ,the guage cluster weighed 10 lbs to about 1/2 lb for the cavalier etc) i have shaved off around 150 lbs .when i do an acceleration run ,the car sits dead flat ,no up and down motion .i guess i cant really say how it would perform with stock suspension ,because i have tubulars and coilovers all the way around .
there are kit pieces available to make it all simple .his name is roger thelin ,he had a car at daytona this year .contact is kmunson56 on pff .thanks for posting .

So you are going to stick with the stock ECU to run it? How much boost do you plan on running? I'm not sure if you have the older non VVT ecotec or not but if you have the newer one, I would have assumed the Solstice GXP ECU would have been the one to go with. Personally a piggy-back or stand alone is the way to go. Also be very careful it doesnt take much det to destroy a ring land on non-forged pistons.

2004 non VVT 2.2 litre .the only VVT models are the 2.4 and the 2.0 turbo motor.i havent seen a 2.2 listed as VVT yet .i am planning on 10 -12-psi boost this year and the stock ecu looks like it will handle it .next year i am getting the hahn racecraft portfueler system .it has its own controller .

10-12psi!??? What are you doing to reduce the ignition timing and add fuel while under boost?
