I like projay's stuff really nice guy too. but maybe with runners that run parallel on the upper manifod and the same lettering in the factory manifold. I realize I'm just being picky at that point as the products are already great performers but the cosmetic changes would make it perfect IMO.

The pro-jay system is designed for the big boys. The lower intake has a rail in the stock secondary location and a second rail behind it. Plus the one on the upper intake for a total of 3 fuel rails each housing 6 injectors for a total of 18 injectors (plus the stock primaries, that's a capacity of 21 injectors).

The Xcessive LIM is certainly an impressive piece of work, but I see a few flaws in it.
1. Fuel rail fittings: NPT ports may work, but I would have some concerns about long-term serviceability. The majority of aftermarket fuel lines use AN fittings. In the case that a NPT to AN adapter breaks off, extracting the remnants is quite a bit more difficult. Anyone that has attempted to use a Bolt Extractor can vouch for this.
Depending on the material the rail is made of, correcting this flaw could be as simple as welding on a couple bungs. And in the case that one does break off, it would be much easier to replace by grinding it flush and welding on another $4 bung.
2. Shortblock flange surface: I'm not a machinist, but the flange surface needs redone. I can see grooves that would catch a fingernail easily. Someone more knowledgeable than I can weigh in on a proper specification, but the flange appears to be beyond the tolerance of a normal gasket. A suitable machine shop could correct this though.
3. Runner Height for shorter LIM: Defined Autoworks' install kit is pretty much the accepted norm for making a 20B FD. I believe that it would be much simpler and easier to adjust the height of the modified LIM's runners to suit the Defined Autoworks kit, rather than reinvent the wheel and try to make a kit to fit the current Xcessive Modified LIM. It appears that there would be enough room to remove about 1" more from it under the injector bungs, but this is just speculation. A proper side-by-side comparison by Logan would be the best way to determine how possible this is.
The product has potential, it just needs the flaws ironed out so it can really shine.

If it's 20b related, getting charged out the *** is common place. Hell look at how expensive our 20 year old used engines are? Lol! Thruthfully this will be a low demand low selling product so the cost will what it is. Im sure there's quite a bit of money invested in this. Give the guys a break.

it will not fit.. logan swears that for his kit.. the LIM needs to be lowered 2.5" for it to work..
ive requested with xcessive to test fit it their LIM with my DA kit.. but theyve stated that they have their own mounting kit in the works..
there are certain things you can do to get that other extra inch as there is some wiggle room with the DA kit..
not sure i want to be the guinea pig on such an expensive piece though... perhaps phil will chime in with what hes found and share this time..

Gold Wheels FTW
Figure you have $10k in molds, $5k in a first run of 20 parts, and only expect to sell 10~15 manifolds over the lifetime of the product.
15,000 / 15 = $1000 each, and that's not including any profits for your work. The price is really where it needs to be for it to be worth manufacturing. People don't make things to break even. If you want cheaper, buy a used OEM manifold.
20 year old motor or not, there's no modern 3 rotor replacement, and if no one else is making anything newer or better, then it's still the best option for the most power in the most efficient way.
