Silicone hose kit, e30 M42

[DesktopDave]

Figured I'd post a quick review of this item (http://www.hiperformancestore.com/HoseKits.htm#BMW). You can also find them on EBay as seller "hiperformancestore (http://myworld.ebay.com/ebaymotors/hiperformancestore/?_trksid=p4340.l2559)." Search for "318is" (he has a lot of listings) and you'll get all the color choices. He currently stocks black, red, silver, blue and even purple.

I ran into a few small difficulties, but I've contacted the seller to let him know. Once he responds I'll post the rest of my review. I don't have any long-term experience with silicone hose, but I'll update this as time goes on. I'm recommending the kit with small reservations at this time.

BTW, that is a cigar cutter included with the kit. While it seems like a mickey mouse tool, it worked perfectly (even with mech's work gloves). Just be careful not to bend the blade while you're cutting. It is tough enough to cut high-pressure OEM fuel hose too. The silicone lube is a nice touch as well, much appreciated.

did this come with a hose to replace the hose that goes from the bottom of the overflow tank to the plastic piece under the intake?

[DesktopDave]

Nope. I'd figure that would make a great kit, one to replace the coolant hoses. He stocks one for the M20 but not the M42 from what I've seen.

I'll let everyone know where this goes; from what I've seen silicone rubber seems to be one of those miracle materials that are a true improvement over OEM.

[keflaman]

I have to admit I thought any color other than black would look too ricey to me, but after seeing the red car with red hoses I'll have to retract that thought.

Looking forward to further updates.

[DesktopDave]

I hate to admit it, but I was sorely temped by the purple hoses. My kids would have loved that!

darn, That is the only stock cooling hose I have in place on my m42 swapped car and I would love to upgrade it. My engine sits fairly close to the radiator and my alternator fan keeps grinding away at the stock rubber one. I know its not going to last long so I need to get a replacement. Anyone know of a silicone version of the overflow hose?

[Hey-u]

I picked up the Kit from Hi Performance Store. Very good service and they seemed to truly interested and knowledgeable. The kit looks good but I haven't finished the install. Black of course.

Found this M42 rad hose kit but haven't purchased.

Could you use a stock hose & just bend it as needed? This kit I installed is all straight lines, none were pre-formed. That would have greatly helped with the ICV to intake elbow - I had to move the entire ICV to make it all fit correctly.

From what I've seen, some grades of silicone aren't as abrasion resistant as the OEM rubber too. I worried about that when I pulled a few too-tight barb fittings apart and a little of the red silicone abraded off onto the barb.

[monty23psk]

Dave, did you remove the heater plate with this install?

[unt0uchable]

Dave, it's funny you should post this kit because I was checking it out about 3 weeks ago about midway through my "mess under the intake" delete. I was worried about spending the money and the realizing that I would have a mess of left over hoses since I deleted all the crap under the intake. Could you list what hoses are included in the kit? That would be awesome, and possibly make me go for it this time around. What color did you end up with? And do you have any pictures of under the hood now? Glad to see someone else tried it out....

[DesktopDave]

I was tempted to keep some of the pre-heater, but I ended up just deleting the whole deal. I also cleaned out the intake, replaced all the fuel lines (with OEM 8x13 BMW high-pressure rubber line) & swapped in some 4-hole yellow top "Ford by Bosch" injectors.

I'm still waiting for a response from the seller about the short ICV hose before I post a full review. The kit isn't complete from what I'd guess...there isn't enough line to replace all the coolant hoses, only enough to do the vac hoses. I'll go & take a look at what it contains; I'll have to guess about lengths as it's mostly installed. There isn't a lot left over as the vac hoses are about the same length either way.

What color, you ask? Why red, of course! I posted these pics on my profile, but here's a link. (http://s729.photobucket.com/albums/ww299/desktopdave/318i/Hose%20Delete%20Mod/) Sorry for the dirty hoses, haven't cleaned them yet. I hear WD40 is the ticket.

[monty23psk]

I guess ordering the hoses by the foot might be the ticket, at least for me. Just looking at the ones for vacuum from the valve cover to the elbow/throttle plate. The kit replaces so many hoses though. Did the hoses that come with 2 different size end come like that already? Pretty cool kit in the end.

[DesktopDave]

None of the hoses are bent in our kit, they're just straight silicone line. The hose that runs from the coolant manifold to the head was one of the medium sized ones. It fit easily on the head but I had to stretch the devil out of it to fit on that coolant manifold nipple. It's also the only one that I clamped. The rest are just slip-fit, they're really pretty tight.

The only problem with the kit IMHO is that their ICV line cannot easily bend 90deg into the intake manifold. It's too short a run for that. Worse, the largest hose wasn't quite long enough to replicate the stock routing. So I ended up relocating the ICV (reversed & bent the mount) and pulled the ICV elbow (swapped it to the other intake boot port) so that the hose would reach. No big deal, but it wasn't what I expected.

However, I've already gotten a response from Misty over at hiperformance about the ICV; she's quick to respond and even offered to send along more hose. Based on that, I'm changing my rating to "highly recommended." I'm still not sure about ultimate longevity, but it seems that quite a few of the Alfa and Volvo guys swear by this stuff. I'm tempted to look into coolant hoses as well.

[monty23psk]

I need to replace some hoses for the vacuum system so will give this a shot, just need to take care of other items first. Thanks for th reviews and bringing this up to the board.

[unt0uchable]

The only reason I am looking into the silicone is because currently I have 5/8 heater hose and it's compressing under normal vacuum. I need something that's durable and stiff. As someone mentioned above, I'd probably just buy it by the foot since it sounds like that's all it is anyways when you get the "kit". Did the diameters work out alright for you? Your ICV is in the same place mine is now. I moved it there for easier access, I just wish I could extend the wiring and place the ICV right into the intake boot....but looking at your picture, I think pelican sent me the wrong boot last year, lol. Oh well, it works. Looks nice! I'll be looking more into it now...

[DesktopDave]

I thought about moving the ICV out as well, but I couldn't find anywhere adequate to mount it. I'm not sure it'd fit directly into the boot, but if it did that would be ideal. Even better, one of the Bosch right-angle ICV's would make that an ideal solution.

I'll post pics if I go that route.

I'm also not 100% happy about the intake boot stretching out. I'd love to have replaced that with a chunk or two of silicone as well. I prefer the quiet stock intake box and paper filter, I'd prefer to avoid a cone.

[Gerta318is]

Dave,

Which hose did you use for that? Do you remember the letter? I purchased the same kit in black and just started to tackle this ...

Can I give you ring live to discuss?

Kevin

[DesktopDave]

It was the biggest one...hose M I think? I'll PM you my number.

[Gerta318is]

Dave,

So on the coolant elbow nipple M fit easily, F took a bit of work, and A wouldn't fit easily at all. If you used F, did you use a hose clamp at the head nipple? F seemed to be way loose and A fit the best as M was too large.

Good talking to you today! I'll try to put together a "how to" ...

[DesktopDave]

Must have been A. I'll go match them up to be sure.

[Gerta318is]

Dave,

I got A to fit nicely over the coolant elbow nipple and secured it with a hose clamp. I did the same with the block nipple. I used approx. 8" of hose ...

That was step one ...

Hey Dave, maybe you can help. I would like to get some of the hose by the foot to replace my OEM one that is going from valve cover to under the throttle housing. Right now I am using the stock hose, which is 3 pieces. I have to meausre the ID for both ends to make sure I dont need a reducer coupler or even a 90 degree which this company sells. I would like to keep the stock path. From your pics I see you ran it not under the intake but what did you do to connect it to under the throttle housing? Once I get this side going I will work on the ICV hose. I am using both OEM hoses but then using an m30 vacuum pre-molded hose to make it look clean, just needed a clamp when it connects to under the intake elbow due to size mismatch.

[DesktopDave]

I ran the VC cover to the spigot on the TB, right under the boot. It's the original BMW routing (minus the preheater, of course), goes behind the throttle butterflies. I'm assuming it's that way to help with some pumping losses. I'd like to keep the throttle plates clean...but it'll definitely be at the expense of the intake runners on this car, eh?

[monty23psk]

Did you use the same hose all the way or did you use a coupler or reducer to connect it to the throttle housing. I recall the throttle spigot is more narrow that the VC spigot.

[DesktopDave]

Same hose. It fit tightly on the cover but isn't all that tight on the TB.

I was looking around and noted a few M42s that had it heading into the intake boot as well. I'm wondering if it requires full vacuum all the time.

[monty23psk]

Thanks. Do you remember the size of that hose?

I am afraind if you move that hose to the boot, you will suck more oil so make sure you have a catch can filter.

[DesktopDave]

I think that hose was the third smaller size. Can't recall the letter. I followed the directions as to the letters, they all fit. The only exception I made was to connect the coolant manifold directly to the head with silicone.

I was planning on installing an air compressor catch can; they're cheap and seem to work well. I'll avoid the usual teflon tape and use sensor safe RTV silicon sealant instead.

[monty23psk]

I will take some measurements to figure what size I need and post it up. The kit is nice, but don't really need all new hoses. Will just go by the foot and figure if I need any 90 degree bends or reducers.

Thanks for all the help. Always wanted to go silicone but never really looked from who.

[visionracingdevelopments]

We do an SFS performance 3 piece coolant hose kit here in the UK.

Looking into doing the induction boot too.

[DesktopDave]

Matches my red hoses...nice. Do you ship cross the pond?

[visionracingdevelopments]

I can do yeah, need to check a price though.

[DesktopDave]

Yep...had the same thought myself about the silicone intake. An alu hoop with the ICV vac fitting (and perhaps a mounting stud for the ICV clip) and two hoses...one from the AFM to the hoop and one from the hoop to the TB. Along with some nice stainless t-clamps, of course. A kit like that would play nicely with a turbo manifold as well.

Hey dave is it me or is your belt for your alternator installed on the wrong side ??? Pic# 9

[DesktopDave]

It's a Dayco ribbed belt. They're notched on the inside & ribbed on the outside. I have no idea why. I suppose it's for her pleasure?

ha ha thats a good one... i guess its reversable if you want to go thru the hassle of taking it off.... mines broke the other day and it was a pita so unnecessary to take the power steering belt in order to get to the fan, alt belt..

[91 e30m42]

with all the silicone hoses you installed how does it run would as im thinking of this as my next project

[91 e30m42]

ive installed mines last saturday and i loved them but i think i missed some areas as i was looking at yours which would be the charcoal canister as i only did the side from the canister to intake

Yours looks a lot nicer than mine does...that CAI really cleans things up.

ha ha thanks i wouldnt have gotten it with out your recommendation.. i got the cai from Kmotors on this forum a while back ago but i think im gonna switch to a simota style carbon intake.. i like it great product for the $$ but i also like the simota style as well... i used some quick detailer spray to clean the hoses after also it took a while to get the hoses on since that little plastic piece from the brake booster to the engine was a pita to remove the hoses that i broke it in half luckily it broke in the right spot that crazy glue worked...
