Hi all...
A few weeks ago I stepped up to the plate and replaced my stock LLY turbo mouthpiece with an LBZ Kodiak mouthpiece. Man, what a huge difference! I've been working a huge thread on DP dealing with this and a dozen other similar mods. Just wondered if anyone over here has taken the plunge?
The versions I'm aware of are as follows:
1. Modified stock LLY mp/LLY stock intake - Grind down the sharp edges of the internal stock mp. The design of the stock mp is so terrible that even 15 minutes with a dremel can make a very noticeable difference. Cost - free (if you have a dremel).
2. LBZ mp/LLY stock intake - Replacing the stock mp with an LBZ mp. The LBZ mp is larger on the intake end (4") than the stock mp (3.5"), so the only way to make this work is to hacksaw a few inches off of the intake and use either a plumbing joint/coupler or a silicone intercooler boot to bridge between the mp and the intake. The LBZ mp has both resonator and PCV ports, so you can do whatever you had on your stock mp. Cost - $68-$195 (most $115 - $135). Currently pretty much out of stock US-wide, though they are supposed to become available later this month.
3. LBZ mp/LBZ stock intake - Same as above, except no hacksaw required, 'cause it all fits together. The downside is the LBZ intake filters are $45-$60, IIRC. No clue how much the LBZ stock intake costs.
4. LBZ Kodiak mp/LLY stock intake - The LBZ Kodiak mp fits the LLY stock intake, though the combination of the two cause the intake to be slightly mis-aligned. Fortunately, the bellows/accordion take care of that. The LBZ Kodiak mp does not have a resonator port, though it does have a PCV port. So... there's a little less disruption of airflow. The downside is that unless you go to extreme measures, the resonator is staying off. If you intend to use propane injection, you probably don't want this solution since most of the kits out there dump the propane in the resonator port. Cost - $68 - $195 (most $115 - $135). Also pretty much out of stock US-wide... again, supposedly becoming available later this month.
5. LBZ Kodiak mp/LBZ stock intake - This is an odd combination, 'cause the LBZ Kodiak mp intake side is too small to fit in the LBZ stock intake. Would require a plumbing joint/coupler. You'd be much better getting an LBZ mp.
Other possible solutions:
1. Some combination of one of the above listed mp's and some aftermarket/custom intake.
2. An aftermarket mp or complete intake/mp (TxC and a couple others are reportedly working on aftermarket mp's, aftermarket intakes, or complete solutions). The only one I know of at this time is offered by KillerBee, and his solution, IIRC, is essentially a modified LBZ full solution. I'm not offering any opinions, just reporting what I know/have heard. I believe KB's complete solution runs around $300. TxC claims his solution is a few weeks off and will kick the butt of every solution currently out there, and will be under $300.
The bottom line is that the stock LLY mp is dreadfully restrictive. Solving this problem makes a huge difference in performance and a very noticeable difference in mileage (.5 to 1 mpg or more).
