Want to install my maf blow thru.What size coupler do I need to put it in stock pipes for now.Can I use fernco ones for now or do I have to go silicone??
 
I dont see this even really being feasable. Depending on if your running the 3" or 3.5" MAS. The stock IC pipe is roughly 1.75". Depending ont he thickness of the coupler sme 2" couplers fit. So you'd need @ least a 2"-3" or 3.5" coupler to make it work.

I can't remember where I got this from.... but it's a DIY setup.

Here's the catch...
- Cut up stock BOV piping
- Need a 2G TB elbow (I think...)
- Need additional radiator hose
- Kinda Ghetto... :rolleyes:

I've been working on a similar setup... I would connect the GM MAF to a coupler... from the coupler to a aluminum reducer that fits inside the stock (1g) intercooler tubing (1.75" dia)... trouble in making it all fit so far.... will most likely have to mod the stock BOV piping or fab a new pipe AND relocate or remove cruise control. If you order a full setup from Dejon Tool, you have to relocate the cruise control to the firewall anyways. Not sure if it's worth it.
