Why you need the feed brand adapter - Mainly for the runners or else you get a vacuum leak (or boost leak, turbo boys).



I was told the S5 LIMs bolt up? https://www.nopistons.com/forums/pub...IR#>/dunno.gif Anyways heres an s5! for comparison.



Get the adapter or get creative.

More angle

I know it's a little lopsided I did it that way on purpose because I wasn't sure how well you could see the leak in the digital pictures.



But anyways when it's perfectly straight the holes are still there, or if not there is VERY LITTLE material preventing blow through.

ahh, i see...

Yeah that's an FD metal OEM gasket pictured. LOL forgot to mention.

Couldn't DR. Dremel make it work with some mild porting to the LIM.I take it you are going standalone colin?

Camel showed me his porting of his lim and it looked ultra close to breaking through. I dunno what I am going to do... Making and adpater would be really easy. Paying hundreds for it is stupid.

The bulk of the adapter could be drilled out of a piece of 1/2" or 3/4" aluminum plate on a drill press in less than an hour. Some cleaning and smoothing out with the dremel and tap it for the hardware and you're done. Not too hard at all. Hmm... I sense a profitable opportunity here. https://www.nopistons.com/forums/pub...DIR#>/wink.png

Here is a photo of my FD UIM. JB Welded the "gap" and am going to make a thick paper gasket. using a S5 LIM, seems to line up better.

Myself I am not going with the Feed adapter. But alot of people thought it was to make it bolt up properly. It is, yes, but not in the way they were thinking. It's mainly to make the runners match up, not bolt holes.



My car won't have a stock ECU in the car.. https://www.nopistons.com/forums/pub...#>/biggrin.png



I was thinking of JB welding a small portion of the gap between the upper intake manifold.



Mine was already mated to a TII LIM, and had alot of RTV to close any gap. I'll take a pic and you can see for yourself how thin the RTV is at that point (I scraped off the big gobs of it which I'm sure was preventing any leak, but when it comes down to it you see how much mating surface there was already).

Peep it!

I am getting ready to adapt an FD UIM to my S5 LIM



So would I still need to get an adapter???



I definitely don't want to pay hundreds, so if someone makes some or needs interest to make them, Count me in...

https://www.nopistons.com/forums/pub...1047683561.gif Why?

Bigger throttle plates



Straightened runners



Whynot?



I think FMIC using stock TII UIM looks pretty goofy.. Simplify!

I for one hate the look of the fc UIM, and you can't see or get to anything under it. For example vacuum leaks under there, its pretty hard to zero in on them. Not to mention fuel leaks etc. Fd uim is suppose to be good for 25rwhp if its ported. Thats what soul assassin told me.

+5mm on both secondary throttle plates is a big help too.



Unless you have a TMIC, the TII upper looks silly, IMO.

And not to mention no more nasty throttle cable wrapping around the entire engine bay.

What throttle cable would you use with this then?



My N/A one won't reach, and the TII one is really long..

I don't know for an fd throttle body. I am using the 3 rotor TB on my fd uim. I am going to use the n/a throttle cable. I was told that will work just fine.

Agreed. Advantages worth the effort.

I did the FD UIM mod to my FC. Will take some pics to share with you lads.

That would be great.. I'm curious to see what people are doing to make runners match without that adapter..

I second that...Any information on how to make things work would be beneficial

I guess what i meant to say was, why use the TII LIM not use the FD? It doesnt bolt to the block the same?



The Fd manifold is straighter. But what kind of turbulance is gonna be caused by the transition between FD UIM and TII LIM.



25 RWHP! Thats a pretty bold claim.

Fd uim will not bolt up. The bolt pattern is different on the irons, not to mention the port runners are larger..

I believe the ports are offset too on the block, no?



Anyways it's either modify the block to accept an FD LIM or modify the UIM/LIM mating flange(s).

I would think that the mating the 2 Manifolds would be easier than mating the LIM to the Block... https://www.nopistons.com/forums/pub...IR#>/dunno.gif

Here are the pics I promised.

Another pic.

And what the almost finished product looks.

Looks great!



But what are you going to do about the gap between the primary runners on the FD UIM to prevent a leak?!



https://www.nopistons.com/forums/upl...1084848539.jpg

Checky

First I will make sure that the surfaces are flat and also use grey import silicone along with a FC gasket. I dont think it should leak after that.

Use the FC gasket. The FD bolt holes need to be drift drilled to suit the FC studs so as to mate to the FC LIM.

Use the FC gasket as your template for all the work to be done. The FD bolt holes need to be drift drilled to suit the FC studs so as to mate to the FC LIM. The FC LIM needs little work in terms of prep for the install. The FD manifold is what needs to be prepped for it to work. The FD ports need to be ported as you did, the FC ports need to be ported slightly to match the FD UIM also the mounting studs on the FC LIM must not messed with to avoid vacuum leaks.

Do you have a S5 or S4 LIM??



Looks great by the way!!! https://www.nopistons.com/forums/pub...1047683894.gif

Thanks. S5.

Only the S5 I think works for this mod. I never tried a S4.

the amount of time you people spend on this fd Uim crap is astounding. I can make a sheetmetal box with a adapter plate and a 90mm throttle body for the same amount

Apex13b

I paid less then 100$ for my FD t-body and UIM. If you can make me a sheet metal box, adapter and 90mm t-body for the same price, I'll take two please. Remember, we all have different levels of fabrication skills.

chuck

Go ahead and make your crappy ass sheet metal box (must look like ****) with your 90mm TB. I got my FD UIM+TB for Exactly $100.00 no more no less $100.00.



How much did you say your crappy box cost you? 90mm TB $200+ aluminium sheets say $40.00 find someone to weld it $200.00 https://www.nopistons.com/forums/pub...1047683358.gif
