Has anyone made a definitive part number list of stuff we'll need for the delete? I've looked through this and the "Mess under the intake" thread, but haven't seen an actual list.

I'm not clear on what size the coolant hose you guys are using for the do-it-yourself bends is...

i used about 4 inches of 1/2" insulated heater hose(make sure its for high heat i melted one heated hose)...it's a bit hard to get it on the lower part, just put as bit of motor oil on your pinkey finger, and it should slide on down onto it, just with a little effort....then plug the other end on to the head.

so again,
about 1 foot (its sold by the foot here, so just cut it to like 4 inches or so) of the 1/2" insulated heater hose.

and 2 metal hose clamps

thats all.

oh and..dont forget to tighten everything down properly, and to bleed the system of any air when your done...or you'll be on red about 1/2 mile down the road.

WARNING!guys who live in the cold: im not already sure about that but if you remove the heater plate, the throttle body freezes up and causes the car to rev high without your aprouval! so -20C isnt the best range to ride this mod. just wanted to say so that you know what can happen.

bet.

since mine's been deleted, i took it up into the mountains, and it got to that temp, if not well below, and it didnt do that...
thats just a "myth" i do believe.

Cool. So, 1/2" high temp heater hose.

As far as all the OEM parts, have you ever seen a list of part numbers that someone would need to order in order to complete the hose refresh/TB plate delete/etc?

Personally, I'm not a big fan of the Help! caps. On my last project car, I capped off the unneeded hoses by replacing the to-be-deleted hoses with a 3" or so piece, that had a threaded bolt a size larger than the ID of the hose, threads covered with some RTV and clamped or double-clamped inside the new bit of hose. Would that work well in this instance? I never had a problem with it on vac and coolant hoses on a 12A rotary engine.

There may be a greater chance of "throttle body icing" at warmer temps with the right atmospheric humidity and air velocity.

Do a search for "carb or throttle body icing" for more details. I picked this one as an example (Ref post #3) http://www.z06vette.com/forums/f5/tb-hoses-leaking-coolant-108342/

i know what it is, but it doesn't happen often or if at all on a e30, unless its just a freak instance..

I have a list of the part numbers I bought when I did this. I can post them up tomorrow.

That would be awesome. I'm looking to do it this weekend.

Plastic water pipe: 11-53-1-714-738
Lower Intake Manifold Gasket: 11-61-1-734-684
Upper Intake Manifold Gasket: 11-61-1-717-761
Valve Cover Breather Hose: 11-15-1-717-858
Throttle Body Gasket: 13-54-1-743-261
ICV Hoses: 13-41-1-721-971, 13-41-1-721-972
BMW Antifreeze: 82-14-1-467-704

For the throttle body studs, I ordered a set of the shorter ones that were supposedly used on the "tropical" models (pn: 07-12-9-908-111). But they seemed too short, if I had to do it again I would shorten the stock ones or find some at the hardware store.

To plug the extra ports on the plastic water pipe, I used the old hose cut with a bolt+silicone+hose clamps. So far so good.

You can get more details on how I put mine all together at the link in my sig. Its also good time to freshen up your fuel injectors and check the vacuum hose on your fuel pressure regulator. I think thats everything, have fun.

I just put the heater plate back on with nothing hooked to it to take up the difference and to keep more throttled volume for better mid range. The hose that comes off the top of the plastic pipe that you would normally plug can simply be plugged into the head. Now both are sealed and flowing just like the factory intended and you don't have to buy anything or use shitty caps that will split in no time. I've done this setup twice and it works perfectly and you don't have to worry about anything.

EDIT: nevermind what i wrote, i was wrong

There are definitely many ways of going about this project. It all depends on how ghetto vs clean you want it to look in the end.

CCR Engineering · « **Reply #58 on:** February 08, 2009, 09:20:41 PM »

I agree, connecting the in and out directly with a factory hose is the cleanest way possible and the safest/longest lasting. The heater/spacer plate looks just the same with nothing connected so when you're done it looks just like it did except no more heater lines waiting to crack. I also used new vacuum/coolant hoses for the PCV and idle control valve so that it all looks stock, just doesn't have the metal pipe running through them.

I'm planning on replacing all the hoses as well as deleting the heater plates. I'm wondering what people are doing about the outlet between the 2nd and 3rd cylinder. Is a simple cap sturdy enough? I know I read some doubts about it's ability hold up (semi) permanently. Or are most of you guys bolting and welding it off. I'm a little nervous about the permanent nature of it as well as I don't have access to a welder (suppose I could find someone at a shop to do it). Just kinda looking for the final say on the outlet. Thanks
