With all the new F I kits for the V8's (Holley for instance) Iam just curious if there are any systems or companies that may make them for the Type 4 engines .

I really like the look of this system. There is a YouTube video of a car with it.

Megasquirt based. The only thing that keeps me from considering it harder is that there is no baseline calibration provided which I understand, there are so many factors that affect it like displacement, cam, etc.

That looks like the same system I helped Chris Foley tune on a car in his shop.

This is the car from which the engine came:

I was suitably impressed. We got it started and re-calibrated to alpha-N, and it was very responsive to tuning changes. Starts and idles nice; not street-reg'd so Chris is going to have to get some dyno time on it for various loads and RPMs. I told him that if his customer ever wanted to switch to carbs to let me know...

I like it.

And this is probably on of the best there is for the 911. Lots of choices but AEM is recognized as a top drawer system.

There's a good thread on Pelican by Al Kosmal. Here's a link to his site:
https://www.x-faktory.com

Any standalone ECU will run a type 4 with a crank trigger

My favorite for the money with now is Link mostly because of the capabilities of the ECU and the great technical support they give.

I think someone here was ragging on SDS, because he couldn't tune it. I told him the cam was too hot, poor vacuum signal, tune with TPS only (no MAP sensor) and he said SDS was a POS if it had to be tuned this way.

MegaSquirts "AlphaN" is the exact same thing as SDS "TPS only", both bypass the MAP sensor and you need to use this for big duration cam(s).
Less duration/valve overlap cams don't have an issue like this.

To the OP, once fully kitted out none of these systems are cheap, there's nothing T4 off the shelf, so you need to fab items yourself or pay someone to do it. The dub shop puts together a "kit' for you but you still have to install and tune it.
Basically you have to research and learn how to tune the system, some systems it's a steep learning curve on the tuning.

If you are moving from carbs back to FI make sure u know what cam u have.

Because of the nature of these cars (no smog )
Carbs are really the way imho
And it conforms to the cheap sob ... Way of thinking


Is there a reason you cant use a subaru
F.i system .... How does it know its on a ez motor
Not a type 4

"Compatible with aftermarket ECU’s
There are many Electronic Control Units available world wide. There are inexpensive systems like Megasquirt that can be assembled by the user; Haltech, SDS, FAST, Holley and Motec are just some of the choice of club racers and professional race teams, available at different price points. Ask your Borla Technical Representative for advice."

No experience with these but they have my interest. Sure are pretty.

My friend's PMO-AEM Infinity setup from Al Kosmal. 3.2 SS, COP.

Looks rather expensive!

Beautiful engine. $35-40K ?

Almost any aftermarket ecu can be used with a T4 but it requires one of two things.

A) The owner must be interested, motivated and stubborn enough to learn the ecu, the sensors and how to wire it. Tuning can usually be left to a professional. (this is how I did on my car) Talk to the tuner you want to use before buying into a system.

or

B) Be willing to pay the cost of having someone else do all of the above for them.

Well Thank You Guys very much,..I have nothing against Carb's I like them aswell,..but in Arizona you can go from 2000' to 6500' and they say carbs are always a issue once they are tuned to a specific altitude give or take a few hundred feet. ??

cb performance makes one, better than carbs, but if you have or can get original fuel injection that would be the best choice (unless you are racing!!)

Is this another project? Did you shelve your conversion?

I'll see if the owner is willing to tell the truth.

+1 for SDS. Install thread link below, along with dyno runs.

I have carbs and have driven my car from sea level to over 12K feet. Sure at 12 K it won’t idle well but if your driving and keep the rpm up it’s no problem. Put an A/F gauge in your car and tune it right and drive it. Once when spending a week in Colorado I installed smaller main jets just for the trip but it isn’t necessary. I’ve taken my car from Phx (1100 Ft) to Flagstaff (6500 Ft) for the summer and only turned up the idle screw and it ran fine. My biggest issue with carbs is they’re noisy and stink up my garage.
EDIT: I'll qualify my statements that my car is not a daily driver and it has a carb cam and I don't have any of the FI components. If it were a daily driver I would probably want FI

I had looked at the CB Performance kit before I purchased the carbs and may, one day, go to it.
https://www.cbperformance.com/Injection-Kits-s/288.htm
This about 2 years ago but, if memory serves correctly, they said they could get a setup for a T4 for about $2800.00 (don't quote me on that, my world has changed a million times since then and minor details from conversations don't always make it back up to the top)

Im kinda confused ... Seem like a every guy in a 914 would want To buy cb fi.except it cost about 3x
More then it should


Computers are more complex
Then a screwdriver

So carbs have the advantage there

And cost
And wot performance

And fire saftey

So the trade off is pretty clear cut for me .


Since i dont really care about
Start up warm up etc

Don't try to argue with someone who thinks every modern car company made mistakes by going FI over carbs.

The rest of us do care about start up, warm up, elevation changes, etc.

In this day and age it is just getting dumber to think FI is inferior.

Having said that, I do cheer the carb experts.

Fuel injection failure at extremly high pressure
Can produce flame thrower effect

Where as carbs at 3psi will just burn up the car not the driver

Modern water pumpers should have f.i

But smog except air cooled porsches....
Seems like carbs are more era appropriate

No Sir 76-914,..still in work,.!! just wanted info for parts for my other 914,.and if Carbs are good enough for Michael7810 then they are good enough for me,.because 2nd 914 would be running up and down Arizona aswell.!!and Ive been told that carbs ALWAYS needs adjustment and thats a pain but a few times a year I can live with.

I know but I cant sit quiet and let him unopposed declare his opinions as the truth.
I dont mind carbs at all but anyone asking for advice should have as detailed a picture as possible to make their decision from.

Aftermarket fuel injection has a higher knowledge and dollar threshold but once installed and tuned will require less attention. (depending on where you live and how you drive)

Carbs are cheaper and easier to install but may require more routine upkeep. (depending on where you live and how you drive)

My friend Peep can build you a complete VEMS system. He does complete plug and play systems for several models of Porsche(and other makes) and has done VEMS systems for type 4 engines in the past. I have known Peep for years and highly recommend his systems. He is in Estonia but he provides great customer service to lots of people in US time zones.

Peep has full TUV approval certificates in Germany for several of his systems which is not any easy thing to get.

Just a headsup that there are alternatives within the US.

With the CB kit you still have to have the ability to dial in a carb linkage. A non CB dual TB setup with fuel management is VERY expensive.

VEMS is pretty popular with the 944 guys who want a modern ECU. Plenty of info on Rennlist

Peep goes by raceboy on rennlist and pelican parts. He is the source of 90+% of the info and the VEMS systems on Rennlist(and Pelican Parts)
