Was wondering if any one has any experience with the ZZP L36 HV intake insert http://www.zzperformance.com/zzp/pro...ake_insert.htm I was thinking about getting this because it says the holes for the coolant passage to the TB are not drilled, so this should keep coolant out of the upper intake avoiding any problems due to the coolant leak problem. Also since it appears to help the top end so much, but would I need any other mods first to see a difference or would it work well on its own? For the claimed benefit it seems like a high bang for the buck mod, but obviously hearing some firsthand experience would be good.

That won't solve all of life'* problems. You'll still weaken the upper intake around the EGR. And it may warp from heat and cause vacuum leaks. It'* not been on the market long enough for extended testing. It may not be worth it. No way to know yet.

Hmm...that sucks, is it the heat from the EGR that is the problem? anyway around it?
My upper intake was replaced once under warranty at I think 60,000 miles or so, and I'm at 94,000 right now. Don't want to have to worry about it again in the future. Pretty much stuck with the plastic intake aren't I?

I'd wait till this mod had been out on the market for about a year. Then if it'* not cursed by the L36 community in general; it'll be worth it to try out at that time. What I would do is go with the throttle body plug and intake/exhaust mods first. Then I'd do rocker/cam next. After which I'd do a 10% alternator pulley and the light wieght water pump pulley,( not the under drive pulley). Not sure if the Idler pulley is worth it, but I'll be trying it because of the lack of an underdrive pulley for the 97+ cars. Hope I'll lower my E.T.'* in this way(more power). My GP 3.8ltr. SE picked up .127 in the quarter mile in this way. Hope this happens for the Bonnie as well. DHP would be the last touch.


Hope this helps.

The material we use for the lower insert piece is the same stuff that we have been using on our TB spacers for some time now without failure. If it made you more comfortable we could make the same lower intake piece out of aluminum for the same price I believe.

Zoomer from what I have read the unit gains hp specifically at the higher end. I think I also read it gains its best results with other products you offer. Meaning you can’t really gain significant hp without other portions of the engine also offering the opportunity for higher RPM power.

Yes ? No ?

Just about all my high performance stuff that I perchase is from ZZP. My concern about the incert is that someone who is new to the mod game may have a problem with it. I've no dougbt the materials are top notch, but I just want to see if the silicone stuff will hold or crack. If it holds for a while then cool. I'll pony up for two of them as I've two L36'* that I'm moding. I'm just being patient. As it is the throttle body plug is a safe investment. Won't add a lot, but won't hurt at all. As for aluminum incert .... that was a joke right? On the real side wouldn't that add to the heat problem? I'm not trying to flame you or anything like that. Now what I'd like you to do is come up with an under drive pulley for 97+ Bonnie'*

I think the biggesti thing you could do (and make TONS of money) is an aftermarket upper intake. Aluminum or whatever so IT DOESNT CRACK!!! Its an idea, ill pony up some dough to make returns on it even tho i dont have a series 2 L36 i might in the future....
