Hey guys mainly after a aftermarket manifold with external gate

Turbo kit will be a bonus after a gt30 or 3540

Let me kno what yous have

[evo-gsr]

Why not buy a dump with provision for ext gate?

[DPARTD]

Want a proper setup would sound like you have an exhuast leak on idle been there done that on my s15 neva again

[evo-gsr]

Lol..must of been shit setup you had.... Know plenty with this setup, inc myself and have no such sound.

[DPARTD]

What turbo you running?

[BYBY5L]

Nissan turbos and Mitsubishi turbos are apples an oranges,
The t28 or whatever it is, exhaust housing doesn't keep the exhaust gases split, bit shit as even with the gate closed, ya still gunna spill exhaust out ya screamer

Thanks Jamie. At least someone knows what they are talking about!

[DPARTD]

Niceeee

For once hey! lol, I had one with a screamer in nz, lol, presumed they all had the divider attached to the dump, only found out they dont when the mrs bro got one for his 14 and it didnt have it... gotta wonder why they arent all made with it though, should be called a tractor pipe if it isnt there

anyway, what kind are ya chasing? Steam pipe, mild??

[DPARTD]

What would you guys recommend? basically after the ones that dont crack

[Evo-00x]

In my personal opinion, if weight isn't an issue, e.g. you aren't building a competition car and trying to save weight, then buy a steampipe manifold from 6-Boost, or have one made using a proper merge-collector with short and equal runner lengths as possible. After its made, get it HPC/ ceramic coated to protect the metal and welds from rust inside and out. This helps keep the heat inside the manifold and assists with airflow too. It will be weighty, very weighty, so when you hook your dump pipe up later, add an extra dump pipe brace in there somewhere to help hold the weight off your exhaust manifold studs. I have yet to see a steampipe manifold crack even if its welds looked like bird shit.

 

On the other hand, you could go with a stainless steel manifold which is lighter, aesthetically appealing (well at least for a little while), wont rust, and helps with keeping the heat in and airflow. But it would have to be built by a reputable company that has had their manifold tried and tested and at least know that the numbers mean for stainless steel grading!  

 

DO NOT  buy any cheap Chinese piece of crap SS manifolds EVER!! Your home vacuum cleaner pipe would be stronger than the shit that gets classed as 'exhaust manifold piping' that comes out of China these days!. I've seen too many stainless steel exhaust manifolds crack at the welds or actually crack at the pipes because they were either built using the wrong grade of SS, shit grade fake SS, or they just couldn't handle the constant vibrations and weight of the turbo and exhaust over time that the welds or piping got stress fractures then cracked apart.

^Top reply there Rob,
I paid 40 bux for a chinese one, no intentions of ever using it except to template a steam pipe one off it, I'll try dig it out cos the bloke who had it had heeeeaps of repairs, from blowing holes to cracking next to the welds,
No matter how tight the money situation is dont get the chinese one,
holset turbos seem really good for the dollars being asked too, few people on here rate them too

[evo-gsr]

Love my Holset.

[DPARTD]

Thanx for the advices guys actually picking up a holset Hx35w

[evo-gsr]

Good choice. Being such a big heavy turbo I would recommend getting the FP cast mani.
You will need to mod water pipe and radiator fan to make it fit.
Did you get it with BEP rear housing??

[caged]

What mm inducer hx35? They are a nice set up and make good power, just resonably big to fit.

[evo-gsr]

Its worth it....^
