im currently putting together a turbo kit for my le5..and for the life of me i cannot find a turbo exhaust manifold maid for this car..i did read somewhere that i can bolt on the lnf's mani ..is this literally our only option aside from fabricating a custom exhaust manifold? and lastly ..i understand the restriction of the stock exhaust manifold but cant i bolt my turbo right on to my stock manifold and focus my concerns on making a dp? is that possible? what would i be risking ..please and thank you!

 

if you're not sure where to find a manifold or how everything should be bolted up, i don't think you should do this project quite yet. manifold depends on what kind of turbo you're going to get. if you're going to get the stock k04 turbo, you will need the stock manifold (i think badmab makes one too, not sure). if you plan on going aftermarket turbo, ttr or zzp will be your answer

 

garrett t3/t4…and ive been on zzp all night they dont specify what exhaust manifold theyr using in the 2.4 kit..and the only exhaust manifolds they sell seperately say ..lnf ..and i think there was one for lsj too but def not le5 ..

Treadstone also makes a beautiful cast stainless manifold if you are looking to run anything other than a factory LNF turbo (which I would not advise, the factory setup doesn't work that well on non-LNF cars)

i do somewhat understand how this system works and ive installed a turbo kit b4 but it was already put together kit and plug and play for the most part bsides welding the downpipe ..now that im trying to put together my own kit yes im a little stuck on the manifold ..but this how you learn right ..by doing it lol ..**** it if i blow it up ill get another le5 off ebay for 600 bucks with lower milage then i already have ..and have some fun in the process

 

All Ecotec exhaust manifolds are physically interchangeable, you can easily use the LSJ/LNF mani on your car. I installed a ZZP kit on a 2.4 and it was the same manifold as the LSJ one at the time, they both even cracked in the same places

 

yeah i did see that one on zzp ..thankz tho man ..and if someone could ..explain to me the difference between a turbo exhaust manifold and my stock em ide appreciate it ..maybe ill get creative and try to build my own lol

 

they are specifically designed for the correct angle to flow the exhaust gases to spin the turbo. slightest mishap on angle/weld and your turbo could spin the turbine backwards and make your car blow up

 

lol of corse

 

i would recommend cast manifold.... had a bad experience with a welded one
ask ItalianJoe1

 

The revised manifold is a quality piece and i suggest you consider it

 

I've got a Garrett mani/o2 housing for sale
