ecotec swap (Page 51/98)

sorry forgot to add that the purpose of the 7X reluctor wheel is so you can run a 2.4 with 2.2 wiring .people are then putting the 2.2 cylinder head on the 2.4 .the reason is it gives them a 400HP capable bottom end .the 2.2 wiring is not compatible with V V T hence the head swap . the easiest ecotec swap in to a fiero is the cav/sunfire 2.2 , no DBW and you can buy a whole car pretty cheap .2007 and newer models have the 58X wheel and wiring that is not compatible with older models .

I've been reading in the hybrid section of ecotecforum.com regarding putting a 2.2 head on a 2.4 block in order to get rid of VVT and not have to use throttle by wire. May elect to go this route instead as it does leave open the possibility of tuning.

Regarding your build, with your upgraded pistons, rods and turbo, are you aiming for more power, increased reliability/durability or all of the above?
Do you expect the crank shaft to be a weak point as it is not forged?

i am looking for more power and durability .the crank in a 2.2 is not forged but it is a very strong unit .it will handle over 500 hp ,a level i am not interested in .if you want a forged crank , the cheapest way is to go LSJ .a whole swap package from a wrecker will cost less than one forged crank from gm performance (and the eagle crank has been discontinued) .the 2.4 does not have a forged crank and it has powdered rods .they are heavier duty but only marginally .this is info i recently dug up that i think is accurate .the bottom end strength of 2.2 and 2.4 ecotecs comes from the massive crank girdle .a lightened crank would be nice but too much work for me .

i have today off and i am sitting here waiting for more parts , which apparently are slowly going through canada customs .these include my camshaft and drive pully bolts , so i cant put much more back together until they come in.in that order , i am also getting the ecotec build book and the 2.4L manifold .i was looking for a used one but no luck there and they are on for 10% off so why not .i have ordered the hahn racecraft HTZ-1085 turbo manifold and the matching 20G HTU-2910 turbocharger to go with it .bill hahn jr. put together a package with all the bolts and gaskets and gave me a great deal .this turbo is not the one listed for the cobalt ss ,it is a little cheaper as i dont need the cobalt specific parts .i am really glad i emailed hahn and asked them to put together a package .i saved 300.00 over what i would have paid if i had just ordered parts off the website , and the turbo should be better suited for the fiero .my old turbo is a 16G and i wanted to stick with that style of turbo as it spools really quick and produces boost at a low 1800 RPM .the 20G is capable of moving a lot more air and pressure can go way over what i need .i have to work nights all weekend , hopefully everything will be here by next week .

i made a mock up on my work bench using my old cyl head bolted to the bench .allows me to see how exhaust and turbo related stuff will fit without running outside all the time .here are some asorted pics.solstice manifold :

why i used to want to use it:


a better shot of my old turbo set up

i seem to be getting a useless collection of ecotec manifolds

Wftb, I'm looking into purchasing an ecotec engine/trans - possibly the 2.0 supercharged if the price is right. Not too sure where to look. Do you have any sources that I can look into?

Thanks

check out the Ontario Automobile Recyclers Association website .once you are there , click on the "search for green parts " button .then you can do a make and model search for a 2006 cobalt ss or saturn ion redline and it will let you pick either the 2.4 or 2.0 supercharged motor .i found a 2.0 for less than 1000.00 but it did not have the supercharger .i found a wrecker near stratford ont that was selling what they called a swap kit to convert a stock cobalt to a supercharged SS version .it included the harness , ecm ,bcm , motor ,f35 trans ,axles , guage cluster and everything that was needed .price was 3300.00 .a little rich for me but only because it had a lot of stuff i did not need .happy hunting.....

i am getting a lot of work done on the new engine .valve cover and oil pan are back on, installed the 2.4L intake manifold and put the fuel rail back on .the adapter kit for the intake swap was not quite plug and play .it includes an adapter plate and gasket to go from the DBW throttle body to conventional TB .the extra bolt as supplied is way too long and i replaced that with a shorter allen socket head bolt .some material has to be removed from the TB with a dremel where this bolt head contacts the TB or you cannot get the TB bolts to line up .also , one of the bolts has to be torqued into the adapter plate and since it is only 1/8 " thick you need to add a nut on the bolt under the plate .you will strip the thread on the plate without the nut .my new turbo and manifold were shipped on the 4th but i am still waiting for it .we have had some more storms and road closures so it is sitting somewhere now .i have brought all my piping and fittings and intercooler in from the shed .i hope to mock up my new charge piping on the engine stand .i am going to try and mount the intercooler on the drivers side of the engine over the transaxle .this will eliminate about 6 feet of charge piping i hope .cant do it without the new turbo and manifold though .this is the only day i can work on it and i am waiting for parts again .have to work all weekend and monday .
