CIS to EFI kit

People have asked about pricing of the fuel rails. They will be $149US each.

I still don't have a source for the brackets, so I will make them myself for now. They will be $3 each.

Let me know if you want a pair of rails for your DIY project, as I wil be ordering enough rails for the five kits next week.

Now all we need is someone to fab up some cheap stacks. $2500 for TWMs is just a little too much for my bank account. Maybe there is something in the VW world that could be modified? There has to be something out there in the junk-yards waiting to find a new use. Oh man, Im super excited about this thing, can't wait to get one.

Wow! I see there are a lot of things to still talk about here. For starters I know that mid seventies Jags use a TPS that is seperate from the throttle plate assembly and is moved by linkage to the gas pedal. Could be a easy way to get a tps on our stuff with not so much muss and fuss. Mounting electronic injectors in a set of MFI manifolds seems not too hard. Am I right that the MFI injectors mount in the manifolds and not in the heads??!! My car has carbs so I can't go look.

Folks,

I've been informed my webpage (link below) doesn't work. It seems like the bandwidth has been exceeded. I guess this is good news, but for now it is bad news.

I need to get a real place to host my web pages. I will looking into getting a domain name and some web hosting. This may take some time.

Are you guys talking trash about my junk-yard scavenging, VW part using, short-cut taking, bad behavior? I know that my CIS system can be modified, but I want stacks dagnab-it! Big, tall, cool looking, stacks

[red-beard]

I can just hear that in Beavis' voice....

I just finished reading this post. Nice work Tony! I'm interested, so put me on your list of potential buyers. I like the way you are looking ahead, since I want to add a turbo kit in a year or two. A new product for you to look into? (hint! hint!)

I think you might have enough interest in your product to make yourself a nice little business. Sell a bunch here and then advertise in the Porsche mags.

Keep up the good work

Anybody going to buy just a partial kit from Tony? Would like to butt heads with anyone who is not going with the full kit.

Tony has done a fabulous job with this EFI kit. I'm sold.

Nice work on your website too. I read that you are indeed serious about adding a turbo at some time in the future. A precise efi controller is the only way too go when a turbo is added, since detonation can be a problem with a cis system. You would have a nice safe setup and put out enough H.P. to make people reconsider a 3.6 conversion, since your price for both efi and a turbo kit will be way less than a 3.6 conversion. You may find yourself busy.

Any Updates???

Partial Kits are now available for order.

Here is what you get:


Kit includes:
- Megasquirt ECU
- DB-37 connector with hood (for wiring harness)
- Six fuel injector bungs with O-ring
- Two fuel rails with mounting holes
- Four brackets to mount fuel rails
- Four nuts & bolts to mount fuel rails
- Two -6AN O-ring to -6AN flare fittings
- Two -6AN O-ring to -6AN flare with 90 degree bend

Price is $750US + shipping (money order only). I can accept paypal, if your willing to pay for the paypal fees ($25).

The fuel rails are the only parts I don't have in stock and need to be ordered. Lead time is about 2-4 weeks for the rails. I am putting an order this week, so email me if your interested.

Subscribing to the thread....

I've been following this thread and would now like to add my $0.02. Its a very cool project. I wish I would have thought of it

But, I have some reservations about not using TPS for accel enrichment. Background: I have a 2.5L 4cyl Jeep (single throttle body) running w/ an SDS and I just got my SC rebuild running w/ a Haltech E11 using individual TWM throttle bodies. Both of them horriblly lean out if the TPS accel enrichment isn't turned on. The MAP just won't respond fast enough to keep the motor properly fueled if you really jump on the throttle. Both of my cars will actually hit lean misfire (>~17:1 AFR) if the enrichment isnt set high enough. I don't see how any system can get around this?

I've read about several folks who have sucessfully used a SDS on their SCs. I have even seen pics of the mod the the throttle body, but I can't find them anywhere now. I recall that one guy machined back the non-drive side of the throttle body to expose the shaft and machined some sort of adapter...

SMD,

I am doing without the TPS, but not it's function. Acceleration enrichement still exists, only the input is not the TPS sensor anymore.

More testing is being done on this, and I will post my results. Note: the system will be designed is such a way to accept a TPS sensor in the future if need be.

BTW, I was the fellow that modified the stock 911 throttle body for a TPS sensor, check my link below.

Tony,

Do you have any rough estimations for availability of your complete EFI kit? Will the complete kit have the fuel delivery mapping programmed?

I guess you'll have your hands full finishing this project before you try the turbo install, but do you guess when that will occur? There is a turbo kit for CIS cars that might be available this year, but I'm holding out for a more modern system that has EFI. Since many of us have been waiting years for a turbo kit, what's a couple more? If you decide to offer a turbo kit I interested in that too.

It will probably be a few more weeks before the complete kit is ready. Maybe end of February.

I've closed on the O2 sensor selection. Instead of using a cheap single wire sensor, I've opted for a heated sensor. It is worth the extra cost because it allows better tuning at low engine rpms (low exhaust temps).

I don't want to get a flood of emails about turbo kits, but it is absolutely on the horizon. I have already collected a turbocharger, exhaust pipes, external wastegate for my prototype. With the EFI kit already installed, the turbo bolt on will be a very simple. I don't have timelines or pricing for this. I really need to finish off on the EFI kit first. I will start a new thread on this topic when I start working on this.

[JK-81SC]

Yep I agree, sorry for putting the turbo before the EFI. I like your work, I'll be talking to you again.

Hey Tony,

Will this system be CARB legal? Does it result in reduced emissions? Is anyone planning to put their car on a dyno so we can see how much of a performance gain is achieved?
