Megasquirt Kits- Group buy/build??

They already exist, off-the shelf. TWM induction, Weber-Marelli, Jenvey, and a host of others make DCOE-type throttle bodies which will bolt directly to your intakes. Add injectors (the placement is already there on the TB's), fuel rail, regulator and ECU and you're all set. But they are costly still...usually $250-300 each.

Hence my reasoning a while back to modify a 40 DCOE Weber into a throttle body (which was in sad shape and missing parts). Lots of labor, sure, but the Webers were free (thanks Bill Daley and Gary!).

Found some links to DCOE-type TB's....

If I was going to build a basic TBI system that'd work on almost all 1.9-2.4L engines, I'd use a Megasquirt box with a GM 2.8L TBI. The GM TBI is dependable and replacement parts are cheap. The 2.8L version is dam-near given away. For more power, use 4.3, 5.0, 5.7 or 454 TBIs. The 454 version flows 670 cfm and has huge injectors. Injectors can be exchanged between models. They can even be honed for more flow, but why on a small engine? The regulator can be replaced with an adjustable one for turbos and such. The fuel pressure is low, so no special fuel lines. It requires a 14-18 psi fuel pump for an NA engine, easily available. All you need is a special adapter, return line and some wiring. Megasquirt can control dual TBIs for those that love excess.

I'm working on a V8 project (not Opel) with a tunnel ram. I've seen people run Megasquirts with true race cams and dual TBIs on V8s. It blows carbs away, more power everywhere and every time they tune it they make more. I know one guy that used a pair of Holley 660s for years and the TBI system ran better off the start.

I'd shy away from Holley TBI units. I've heard complaints about the expense of replacement parts. The GM parts were much cheaper.

Maybe I missed it, but how much are we looking at $$ on this?
I have my hand halfway up in the air.

[RallyBob]

The price range is in the first post. Depends if you buy the kits and build them yourself, or pay someone to build them, or buy them already competed from a retailer.

[opelenvy]

OK, I did see that price range, I just figured a group buy/build up would all be the same price. So the person building them up will do what?
But I'm in for one, regardless.

I am in the preliminary stages of converting my 72 GT to efi, and have the system components off an Ascona, but none of it has been on and running. If I'm following the thread correctly the Megasquirt would fit onto the old efi system, right? If that is the case and the system would then be tunable, I would be interested.

Yes, it'll work with the old EFI parts. However, the air flow meter will not be used and you'll need to add a throttle position sensor, either by attaching to the old throttle body, or just replacing the throttle body with one that already has a sensor installed. The other differences are pretty minor

bob with christmas coming up its cruel to put links up to things like this
now the kids miss out and the dogs dont get there treat for doggymas
that would look so nice on mine droooooooooooooolllllll

On the Megasquirt pages I saw where there is somebody already doing the mass buy thing and sells it all for 140 in kit form. What is the advantage to a group buy if the price is higher and you get a third or fourth person involved?

[Gary]

It looks like there is no advantage in a group buy for the kits. (I wonder if the eBay seller would drop his price for a group buy.)

Maybe there would be an advantage in a group build. A member with the skills and time could make some $$ by assembling several at once and become a megasquirt expert for Opel applications. Just a thought...

[nobody]

With the direction I've taken on the turbo concept I'll probably do the megasquirt to control the fuel injection. For the price it looks reasonable and some of the other pieces seem to be easy and cheap to get. Currently I have the tps, injectors and the added temp sensor looks easy to add when I do another thermostat housing rework. I have no problem answering questions if I've been down that road to have any experience.

[T-6 driver]

anyone ever tried adapting a gsxr 750/1000 throttle body assembly (custom manifold)? I saw a dude that did it with mega squirt, he loves it, LOOKS SWEET!

I just got an Email on this topic.

Dave,
On an order of 10 or more units, I offer a 5% discount, so the ECU
kit would be $133 each.

98954.021K
Cast 40 DCNF, 2 inj. Dual
body kit with, fittings, stacks,
TPS, reg, levers

would this throttle body fit onto a 1.9 gt, and anthor qustion would it work well on a basicly stock motor?

[nobody]

The DCNF is downdraft but you'd need an adapter to go to a stock intake. do you have any pics of it?

[roadkill]

Let me chime in for a second. I can barely spell fuel injection, but earlier in this thread you were looking for someone to solder a bunch of stuff up. I'm a fairly hard-core computer geek, and I'm no stranger to soldering electronics (I did a lot of EE on my way to CS). I used to do a fair bit of robotics etc. and I know how to make things hold together during heavy use/vibration. I've also done a fair bit of surface-mount PCB population.

I'll probably pick Dave's brain regarding fuel injection vs. dual carbs. . . I'm thinking that fuel injection, properly set up, probably demands less day-to-day tinkering, which would be a bonus in my book.

Regardless of my direction, if you need sombody who can follow a wiring diagram, knows a diode from a resistor, and can solder I'll volunteer some hours.

All best,
Mike

I'm trying to get an idea of how much (total) setting up EFI is likely to set me back when it's all done, but my ignorance is astounding. So, the Megasquirt kit is pretty reasonable, but I'd still need some sort of manifold, fuel pump, fuel rail and whatever sensors this set-up requires (O2, MAF ????). Does anyone have a ballpark estimate of what the whole conversioin would cost? For the record, I'm broke, and live near good junkyards. Thanks, and sorry to be a drain on the brain trust -- I'm learning, honest!

[nobody]

I like that price but for me personally I'd like the group buy. I'd put it together myself. At some point before I build another motor I'll be doing this so I can have the intake and exhaust done first so I'll know what kind of motor to build. I was rereading this thread and it looks like with me included the number is maybe 5 or 6 buyers and about as many assemblers.

[GT-Freak]

Megasquirt can be used on any fuel injection system. It can be as easy as scavaging a simple all-in-one TBI system, with sensors and wires off a junker and bolting to a stock intake, or as complicated as converting mechanical fuel injection to electronic, or even built from scratch systems. You choose your comfort level. Note that fuel rails require some special tools.

[RallyBob]

Are we any closer here to getting a group buy together, or should we wait until after the holidays when people are a bit more solvent?

Bob

[opelenvy]

I, myself, would prefer to wait until after the holidays.

[Sportwagon75]

The group-buy price looks reasonable enough for me. Count me in when the time comes. However...I'm with Bob. After the holidays would be more practical. -SD

[nobody]

So far it looks like the head count is Gary, Bob, Samdog, Opelenvy, Sportwagon75 and me. Getting closer but unless somebody is looking at more than one it is still too few for a group buy.
