Hi,

As I am using the car is a daily driver I've decided fuel injection is the go. The powerjection TB system seems to be the best bang for buck with the least effort (In the mid 90's I was working with Moates and the guys on reverse engineering the '95 HO ECU using a J3 port board and PCMX and just couldn't be bothered again).

I've ordered parts from Summit Racing before (years ago) but I was wondering what experiences people have had with the other performance mail order shops?

Why bother buying an electronic carby?

We've fitted the Delco ecu to blown smallblock chevs, blown EB 5.0 strokers and many more, with much success, and dirt cheap, with parts available anywhere. One of those computers on a 355 Holden, with a blower, made 700hp at the tyres, and got 8.1l / 100km's on the drive to Summernats

Hi,

The main appeal of the Powerjection is the ease of hook up and self learning. Most of the aftermarket multiport ones as just batch fire anyway (If it doesn't have a crank sensor than it can't be sequential).

I put a 95 HO motor into a Triumph Stag in 96 and I don't want to go through all that again. The big turn off is boring the hole into the firewall for the wiring harness.

Powerjection also make a multiport style setup with the EMS on the throttlebody but they claim there is no performance gain (Which I'd believe.)

I did get the 5.0l motor up to 210 FWKW using unported gt40p heads, 1.6 roller rockers, explorer intake, and a B303 cam. I reprogrammed the ECU with cobra fuel and spark maps and fiddled with the idle parameters until it idled like stock at 700rpm.

I suppose you'd have cool factor, but otherwise, it would be no better than whats on the car from new.
If you look at factory engines, the 302 XT GT had 230hp (165kw), the 302 EB/EL GT had 200kw, measure more conservatively, and with better economy. That is what PFI does for you. Sequential injection on the commodore, was only worth a 5kw increase, so no big deal. Holden never bothered with an electronic carby, ford only tried it with the EA 3.3 & povo 3.9 6's, and then gave it up.

If only the pockets were deeper:

What about the edelbrock setup? Any good?

Mrs BLKPNY · « **Reply #6 on:** July 17, 2012, 06:27:50 pm »

Which one? If it is PFI, it's worth the hassle, otherwise, I wouldn't bother.

This one http://www.edelbrock.com/automotive_new/mc/efi/pf_intro.shtml for example

There are lots of aftermarket EFI systems now - Edelbrock , MSD , Powerjection ...etc.
Many do not require a return line (ie. MSD I think) to make it easy.

I would log onto Summit Racing and check them out.
Probably the cheapest place to get it from.

Having said that - nothing wrong with a properly setup carby ...

Cheers,
Frank.
