That being said reasonable best bang for the buck mods. I currently have the ec pulley,ec tune,ec headers, ec tcu, intercooler with Johnson pump, belt wrap kit and kn drop in filters. The only other thing I'm considering is the quaife lsd. The upgraded throttle body and intake are way too expensive imo for minimal gains, over $3k and I keep hearing issues with the throttle bodies. Thoughts?

Maybe meth?

He has headers so his cats are gone

Meth, killer chiller, trunk tank, fuel rail, injectors, heat wrap everything, torque converter...

I have seen several 82mm tb kits in the classifieds sell for 1000. At that price it's around the same bang for your buck of headers. Just have to check all the time.

vikingdiesel

I'm confused about these 82mm throttle bodies, isn't stock 82 mm? What's the performance gain with the upgraded one?

vikingdiesel

Decent power increase?

vikingdiesel

I don't have long tubes, so I still have the secondary cats. Would getting rid of the secondary cats and putting a straight pipe make a significant difference?

vikingdiesel

Can I have killer chiller and an intercooler? What's trunk tank?

Hulk

Sec cats won't make a huge difference anyway. Maybe 5-10hp if that
No with killer chiller you eliminate the heat exchanger, trunk tank allows you to hold more volume of water

vikingdiesel

Ok, I'll skip on the killer chiller and sec cat delete since I just got an intercooler

What are your thoughts on the ftp intake and meth kit?

vikingdiesel

Do I really need looped fuel rails and bigger injectors with my current mods?

Hulk

No on the intake stock flows very well with kn filters. With your current mods u don't need rail or injectors . Meth is to cool the charge but at your mod level I doubt you are heat soaking

From personal experience I went through shorty headers => 180mm cp to then MBH headers and got rid of the primary cats. Finally added the 82mm TB and had a dyno tune by OE a few weeks ago. I'm not sure if it's a placebo affect but I felt the biggest gain from the TB. Our oem TB is 74mm btw

vikingdiesel

But then if I get the bigger throttle body, I should get a new intake system? What's the best bang for the buck throttle body and what kind of gains can I see?

boostiality

You don't need a new intake system, just the bigger y-pipe.

Check the classifieds as there were some complete TB kits going for under $1000.

Just an FYI Benzworks stated that I needed 550 injectors at this point.

vikingdiesel

only kit i found was $1600 with y-pipe

Get a used 80mm snout ,bore it to 83 mm ,get a used MB S550 82mmTB ,make necessary mods to snout ,welding and drill and tap ,plug and play ,do a search ,there is a DIY on it here for this mod ,and there are a few people selling them on here check classifieds ,

Do you have any MB connections that could get you the intake snout at cost? It's about $325 if I remember correctly and then have the stock snout bored out to 82mm and have extra material added to relocate the holes cost me $300 and then you can buy a used MB 82mm tb or you can buy a new Porsche GT3 82mm tb for about $300. When you have it installed all u have to do is switch a couple pins in the plug due to the tb blade opening in the opposite direction. I bought the 82mm y-pipe from TTM for just over $300 but that was only so I could get the car smogged. So not including install you are looking at about $1300

TheTherapist

Do the intake yourself. You can buy a 3 1/2 inch Y pipe on eBay for $39 plus 2 Spectre filters in 4 inch housing in and out will set you back a bit over $100 add a few clamps then the expensive part which is the pipes as you'll need those fabricated. Maybe a little heat wrap and you're good to go. Still works out far less than what they're asking around the traps and will have you looking good under the hood. Of course that Y Pipe price might vary once you throw an 82mm in the mix. Here's Boosted-AMG's effort:

Throttle body, Quaiffe, DCT steering wheel Custom Re-tune.. Good to go.. Throttle body Really helps when you have headers and are pushing more boost, more air in, more air out... Good luck..

vikingdiesel

What kind of pain gains can I expect from the throttle body? Why do I read on here that some people have issues with them at certain rpm
