Detroit area shop that builds and deals with ecotecs?

Saturn and cavi forums will have the most amount of info.

Just dont use a Saturn PCM, they cant be flashed yet. Dont know why?
 
i dont know anyone that has alot of dealings w/ them, but i know dave buckshaw @ livernois was talking about starting up a program for them
 
I have no time right now to dump the resources. Just follow the GM build guide its has tons of useful info on how to extract copious power out of that engine.

I had planned on that. I was hoping to maybe speak with a shop that had done a few of them and had more input on removal of the balance shaft, going to an electric water pump and wet sump oiling system set-up. I dont think a dry-sump oiling system would be good for high street mileage. The cook-book also suggests to cut off the oil filter housing and block it off at a certain point. :dontknow: Sounds kind of goofy to me. I'd also like ot not o-ring the block and go to a damn copper head gasket.


Plus its always nice to be able to speak with someone in person and maybe see a few motors they are working on instead of speaking over the phone or driving a million miles.
 
1400 for a GMPP ported head, 1500 + machining and balancing for bottom end work (crank, rods, pistons). Sleeving the block+other blaock work (head studs, oiling mods, main studs). Plus turbo and trying to get an automatic RWD tranny to work with this thing.

I can make pretty good power with an old style 355 for $3000.
Real good power.

I know. This is looking like a lost cause at this point. Although a turbo ecotec in an s-10 would be cool. It would probably never run the # either.

Hey, different is cool, but at what cost?

Looks like the E/T will probably never be where I'd want it. These guys on ecotec forums are boasting about running 13's with a turbo and a ported head and cams. :icon_eek:

One guy cant nip 13's with a 2500lbs. car, 5 spd, stock bottom end with ported head, camshafts, throttlebody and full exhaust. :dontknow: Sounding like a set of heads on my stock bottom end SBC would be better than going to this motor.
 
I can build a real nice steel cranked, forged piston, 355 shortblock for
less than $1000. At $3000 invested, you could be at nearly 500 h.p. if you
spend wisely.

Trans isn't a big deal. a 3.4 camaro trans will bolt up but getting the reducded diameter input drum to hold the power your aiming for would be tough.

There was a guy at one of our races this year running bottom 13's with a mostly stock Cobalt SS. I think all he had done was a pulley and unhooked the catback.

For alll the money you are going to spend going that route.... Grab a new crate motor for a turbo Sky, or Soltice.

2. Does anyone make a flywheel for the ecotec that will work with a th-350/200/700 style converter?

3. Who are some reputable shops to have machine and block work done to an ecotec? I am un-aware of any and have had little luck finding one close to me.

4. would I be better off buying a complete motor with a computer and wiring harness and make modifications as needed to the power level I want to make or should I just piece it togehter buying parts separate. I know factory LT1 and LS1 computers can be calibrated to work just fine with stupid power levels.

5. How much boost will a stock plastic intake manifold hold? Or would I be better off trying to make my own. I wont pay 1000 for an intake or exhaust manfold.

6. How much money would I be looking at to be in the 500-700 hp@ the crank range with a turbo?

7. Any suggestions and input is greatly appreciated.

1. the ECOTEC does NOT have the same bellhousing as ANY other GM engine. So no, there is no cheap trans that bolts up to a RWD ECO application.

2. For all intents and purposes NO. your looking at a bespoke flexplate if you intend to use a THM trans.

3. I am unaware of many shops I can recommend, Ive had good experiences with mantapart but many others have had poor ones. Katech will build damn near anything gm and they are world class. gm offers the ready to race blocks and heads youll need for as much power as you want to make

4.it makes almost no fiscal sense to use ANY stock parts at 700hp.

5.the stock thermoplastic intake CAN support about 450hp but I dont recommend it for anything past 350-375.

6. starting from scratch a complete long block assembly, accesories, enine management, induction, fuel, and exhaust systems will will QUICKLY exceed 12-15,000 dollars not even considering the custom bellhousing, flywheel, built trans, and fabrication youll need to run a 9 or 10 second truck.

7. I say go for it. id loved to see an S-10(i hope your not thinking about a full size truck) running a wicked 25-30psi 700hp ECO.

However. you could build a 2-3 second quicker small block powered vehicle for 30-50% less investment, and 95% less headache. But youll be 110% less original.

Words of wisdom right there. Do you want to be cheap or different.

I will check the bellhousing tommorow. I have a core engine and a 60v6 trans.
