Was wondering if maybe someone had some info on this this setup. I've heard that some grinding of the manifold must be done in order to fit properly. Since this is my Daily was hoping someone had some info or pictures on this. (to minimize down time) I would like to have this performed while at the machine shop before the ceramic coating. ANY info on this would be very much appreciated. Thanks

 

Just call Brian @ BNR and I'm sure he could answer that for you.

On top of that, if clearance is an issue, I'm sure, for a fee, you could send him your X-LIM and he could resolve the clearance issue you speak of.

If you're getting your turbos redone by Brian, you're going to have to send him your Y-pipe that he extends. I'm sure he could figure something out for the LIM to make it fit.

 

I'm not familiar with the differences between BNR turbos and stock twins, but I've been running an Xcessive LIM with stock twins for a few years now. There were some modifications required to make everything fit, including bending the oil and coolant hard lines, removing some material from the LIM to add clearance for the y-pipe, and reshaping the turbo heat shield with a hammer. For me the toughest part was re-clocking the turbos to add clearance for the y-pipe... that is how Dan Chadwick made his fit but I never figured out how to do it. Instead I ground off part of the lower Y-pipe flanges to make it work. I think I posted some photos in a build thread on another rotary car club forum, but I'm having trouble finding them via a google search.

 

Thanks for the info fellas, I performed a mock up and did have some minor clearance problems. Thought I should just share some pics and info. Nothing major, it's just a really tight fit. Probably just grind a tad bit . However my concern is now with the coolant and oil lines. Is this the normal "need to bend the lines" or do I need to re clock the turbo's first? Hoping someone could share there experiences with me. Thanks

 

Do you all run this setup in Sequential ?

 

Yes, sequential

 

Myself at least

 

Hi there,

It is a tight fit! I have fitted mine with the stock twins. Here is what I needed to do:

1 - grind some material off the rear runner and the turbo to get clearance - as per the issue in your 2nd photo. Do both the turbo housing and the LIM, little bit at a time. I have about 3mm clearance now.

2 - water feed pipe/ hardline - photo 3 - I actually cut this off an clocked it forward & refitted. I tig welded it - you could braze it.

3 - the turbo oil line - well I actually cut the threaded bit off with a grinder, then welded on steel AN-6 fitting, and then made a custom line back to the front iron. I still needed to 'bend' this hardline forward quite a bit.

4 - as you are keeping sequential, I found that I had to make some custom 'spacers' to refit all the hardpipes/ vacuum lines, that was the most challenging bit I think! I also needed to move the wastegate and pre control solenoid rack 'up' - but I think that was to clear the xcessive LIM fuel rail......

Hope thats helpful - shout out if you want anything else/photos.

Rusty

 

Thanks for the Advice. Yes , some pictures would be very helpful as well. Thanks

 

put a slide show together of the photos I think will help you most:

Cheers, Rusty

 

can a manifold flange be used with 2 sets of gaskets to move the complete twins assembly away from the engine a bit?

 

Thanks Rusty 13B . From what I see I'm going to have clearance issues with the 99 spec y pipe hitting the xcessive lim. Did you run across this issue? neit_jnf I thought about flange / spacers however i would need some for the oil lines and possible problems with downpipe fitment since i would be moving everything over.

 

Hi again,

yes - I needed to solve those clearance issues. Solved with a combination of:

1 - grinding a sharp 'angle' off the front of the Upper LIM (see photo with screw driver)

2 - grind/ cut the cross over pipe flange - you may not need to do as much as I did, just square it up - again see photo.

3 - 'clocking the compressor housings a few degrees. I would use this as a last resort as the compressor housing have a silicon sealant used - I could as my are rebuilt but not all sealed up yet. You could confirm this aspect with BNR before trying it.

all the best - Rusty

 

Thanks again for the advice and pictures Rusty! I considered re clocking the turbos. Had no idea about the sealant. I'm glad I didn't. I managed to perform most of the grinding on the lim & rear turbo to fix all of the clearance issues . luckily I was able to just make some slight bends on the oil line to front rotor and it worked out for me.The coolant line coming from the bnr's are still hitting the lim. Trial and error I guess. I was worried about on grinding too much on the lim I don't need much, seems like I could make a slight bend to clear it. Again thanks a lot fellas.

 

in this same boat. had my coolant hard line shortened and clocked, should get it back today to see how it fits now. will probably have to get my grind on.

 

I had that issue with my RE LIM and the stock twins. The turbos themselves fit but my y-pipe would hit the LIM. I made a spacer to go between the y pipe and the turbos, I angled it so that its a 1/4" on the LIM side and just shy of an 1/8" on the other. It angled the pipe away from the runner for the clearance that I needed.

 

has anyone overcome the y pipe clearance issues solely by grinding? i've ground down more than i feel comfortable with from the flange on the Y pipe, I've ground down/notched the UIM, and now it's time to do the LIM, but I still don't think it's going to be enough...

 

Wutangben , I was in the same situation as you. I did so much grinding I ended up buying another y pipe because I felt uncomfortable with all the grinding I did. I called Brian at BNR and he told me how to clock the turbo housing I ended up having plenty of clearance afterwards. I assume you are running the BNR turbos?

 

bryan messaged me, said to try putting a header flange inbetween the exhaust manifold and the motor. still going to ask him about clocking. now I want to buy a new y-pipe, just feel so off after grinding mine down.

I'm a little worried with intercooler piping fitment after all is said and done. I've got a greddy v-mount and not sure how much freedom it will give me if I'm moving stuff around.

 

pic's? It was so easy that I was a little mad at myself for not asking sooner.I put two breaker bars deep in the turbos outlets and you can actually turn them a little. You can verify with Bryan first. I didn't think it was possible without taking them apart but he's the one who built them. good luck!

 

No way! thats cool. I wonder about on stock turbos...

 

yeah we clocked my turbos last night, all is good. gotta clock both, otherwise the y pipe doesn't fit.

gotta make sure you don't go too far, or the oil drains might not line up.
