Xcessive LIM Info Needed

Xcessive LIM Info Needed
To everyone running the Xcessive LIM,
I recently bought 4 Bosch 2200cc injectors and need to know if I need the CJ Motorsports Injector Boss Adapters to drop them in.
CJM FD RX7 Injector Boss Adapters
I can not find any info on Xcessive's website saying what size the bosses are. Any help would be great. (I do not have my LIM yet, trying to source one used)
Thank you!

Interesting I was under the impression that we didn't have to use adapters.When I called xcessive manufacturing I told them I had Bosch 2200cc top feed injectors and want to know if I can run them with their fuel rail and LIM.I was told the rail was design for them,but they never mentioned anything about adapters for the LIM.
I just got this of their site
This manifold is designed to use standard rubber o-ring injector installation. Metal spacers/adapters may not fit due to some modification of the injector ports.

I email the manufacture here is the reply, this clears things up.
The manifolds are made to work with stock fuel injectors and do not
directly fit top feed injectors, same as a stock manifold to top feed
conversion.Typically when we send out a top feed fuel rail, we supply
some square profile O-rings that can go on the tips of the injectors
to seal them up when they're inserted into the manifold. The sleeve
inserts can be used in place of our square O-rings.
Thanks

Yes you can use the denso 16mm injector grommets( This is what an FC uses). However this is no where near as good as using the machined sleeves( best to use the O-ring style, like FFE and CJ).
The O-ring'd units from FFE and I believe CJ have a step inside them. This is a better design than the straight through sleeves that some sell, but in doing so the injector rail height needs to match.... I am pretty sure the Excessive fuel rail will not work with the stepped inserts. One would need to put shims under the rail mount itself.

Sorry to bring this back to life again. Looking for deets on the Xcessive as I'm debating whether or not to go with it!
Any comments on the performance and quality?
I noticed there are no vacuum nipples on the xcessive lim like there are on the OEM LIM. Where did you run those lines to?
Any other quirks or things that won't fit or functions I will lose by going with the xcessive? (I already have no air pump and have blocked off those two ports)
Much appreciated!

Or is there a newer/better alternative to the Xcessive out there now?
Is a vacuum/turbo block (a la Full Function Engineering's) the way to go to provide for all the vacuum lines?
Any help/input would be much appreciated!

Based on your questions, I would suggest to spend some time reading about your car. There is plenty of info on what you are asking. I understand you want a fast answer, but every mod you do the car will affect other areas.
The quality is good, It seals where in needs to (LIM to engine block and to UIM).
It is suppoused to flow more even air, due to its even and bigger runers.
The manifold with shift the intake forward and come in contact with the oil filler neck.
Most guys using the Xcessive LIM are runing single turbo and in my case there is no need for those vacuum niples, but you get to keep 2 from the UIM right on that side.
You can use a vacuum block if you want to.
There is another LIM that is realy nice from Elite.
Search and read on.. these manifolds had been around for years now.

Thanks, @Red94fd - the info is appreciated!
This is would be going on at the same time as a single turbo and all the related fuel work.
I believe Elite have been black listed on this forum (yes, I do search and do read, all of this is part of my research... but the search function sucks! One is better off searching on google!) due to unethical business practices.
I bought a couple of ancillary products from Elite about a year back and am not particularly impressed. I have also seen at least two anecdotal stories on this forum about Elite's poor service and build/garage quality.

"Search funtion sucks...!" Lol... I cant be more agree.. no problem man.
I know about Elite and their fair lack of customer service. I personaly was going to order a $500 product from them, but they never got back to me with the shipping cost of the product. Jajja.
Maybe my opinion is subjective about the LIM, but it felt more responsive. I like it and to me, its worth it.

I changed fuel injectors at the same time as installing my Xcessive LIM, and only dyno'd the car after so it's tough to say if there was any power difference. I also tried blocking the OEM primary injectors and just running the 4x ID1000 injectors in the Xcessive LIM, but I wasn't quite happy with idle and throttle response. I added very small 300cc/min primary injectors and a Full Function Engineering top-feed primary fuel rail, and now the car idles better than stock.
In hindsight, there are plenty of people making good reliable power with the original LIM, and I haven't seen anyone prove that the front vs rear airflow balance actually matters (via EGTs or individual O2 sensors). In theory it's probably better, but it might be better to spend money on other things first. If you still have the factory single oil cooler, upgrading to duals (even stock R1 duals) is probably more important than upgrading the LIM. I recently added an oil temp and pressure sensor, oil temps with the stock single cooler are over 205 degrees F even on relatively cool days (60-70 degrees F).

Thanks again @scotty305 and @Red94fd !
Scotty I read your story about the 4 x 1050 secondary and 2x300 primary on a different thread -- sounds great, but was it much harder to tune? Or at least, did it make the tune significantly more unconventional? (such that it would be harder to tweak on the fly, without going into the shop)
Red, that last line was the ticket. "worth it" was all I needed to hear LOL -- I just put in my order! I've (also) decided to stop supporting Elite, and I can't help but admit that in addition to everything mentioned above, the large, ugly "Elite" on their UIM (or manifold extension) is part of the rearson! (The font is atrocious, and to pop your hood and see the word "Elite" is hardly the look I'm going for!)
Last word on BBS searches -- I guess forums are pretty dead these days, that there must be no value in improving their search function. I guess some of us are just stuck in the '00s...

funny, I have the Elite, LIM ported to cosmo and semi-p, UIM cleaned up and gasket matched and Elite letters deleted. Also have their elbow spacer, I have no complaints, got my parts fast and they answered my questions on FB messenger.
Before this I had the Xcessive, the first one I got had casting defects and pores and I had to send it back. The replacement was good and I had it ceramachromed, REW gasket matched and o-ringed. Sold it when I got the Elite.
Even funnier, or maybe sad, the xcessive was in my closet for years and now the Elite is there, always something happens and I can't dedicate the time the car needs...
Comparing the two well, from a runner size and gradual bends just by how it looks the Elite wins. But I haven't seen flow tests nor dynos comparing them.

Yes @neit_jnf as usual everyone's mileage varies, and no retailers are perfect! But with the shadiness that was exhibited and confirmed by several members (and in fact admins), I just can't justify giving them any more business.
Agreed that the Elite LIM looks like it will flow better, though. Glad to hear you deleted the logo up top -- it really is an eyesore. Did the Elite also shift the UIM forward like the Xcessive does?

Yes it moves everything forward same as Xcessive, it also sticks out further from the engine so turbo fitment can be an issue depending on your choice of turbo and turbo manifold. They do offer one where the lim runners curve back and keeps the UIM closer to stock location though.

Just as a caveat, the Xcessive and the Elite manifolds may not have adequate clearance with the turbine housing with many of the single turbo manifolds out on the market. If you are in a bind with needing a spacer, we currently offer something that may help you.
