Exhaust Manifold

[ShiftyTys]

Hey all, just a quicky.

Im after an exhaust manifold needs to be low mount, needs to suit my GTX3076 internal gate.

I was looking at the HPI ones for the GTST. then obviously theres 6 boost, but duno if they are low mount.

Theres also alot of faf about merged collector? etc etc. are the HPI ones a merged collector like the 6boost ones?

Can anyone suggest any alternatives?

Bit of money to spend so i appreciate any serious advice or experiances.

Cheers

source a HKS cast low mount = one of the best mani going and they don't split or break and are true low mounts [not side mounts]

get the 6 boost...lifetime guarentee of awesomeness...

Though you do have to modify a few things.. i do beleive the HPI sidemount will bolt straight up with everything in the same position, Tao just fitted one similar to his car check his thypergear thread..might be a good option for you..

yeah thats why the HPI seems a good option. Do they flow well or do i go for above " HKS cast low mount " if i can find one?

[ARTZ]

yes they,re near impossible to find..plus you will need a new intake pipe and new dump fabricated, same with 6boob..HPI is your easiest choice but......yeah how good they are I dont know..

You can get your stock manifold honed out as well is another option but none of these are really going to fix your problems much, I honestly think maybe your better off going highmount or swapping that turbo which will cost you about the same as a manifold anyway....i dunno

Check out stec-motorsports. Could be an option for you.

Hpi seems the go after that read lol.

Any manifold you pay less than $1000-$1400 for, you are going to run the risk of it cracking.

The quality simply is not there yet from the China stuff when you subject it to extreme heat, weight etc. They just crack.

Even the RB26 Tomei manifolds crack and you pay $1000 for those! You really need to spend to get quality in the manifold area. 6boost are a SAU Trader, i'd be dropping them a PM if i were you

[ARTZ]

yeah dunno ,they could be alright..I just thought it was a funny thread

..thing is any manifold will crack, under duress even the stock on doesnt last long...if you dont mind taking it off every now and then to fix it, which is fine if you do it yourself in the shed on your time off..if your paying someone to fix it you arein for alot of heatache..buy the best buy with confidence...6boost

Stock ones generally are perfectly fine. Rare to see one crack as plenty have been running 250-300rwkw for years without issues.

If they do crack its because someone hacked up to weld a gate on, or had the full exhaust weight hanging.

[ARTZ]

what about tracked cars with stock manifolds, do they hold up alright??

[R31Nismoid]

Yes.

Think about stock manifold RB26's @ 400rwkw they are fine as well.

Stock items are good, long as you don't screw with them (weld gates, poor exhaust support etc)

Hmm IN fact i have discovered that the rb25det stock manifold is not aligned properly

thats there over hand on some of the port

If you ahve a anifold lating around go check it ( stick a good gasket over the top of the ports and see that it don't mach up

i have sen that all the ones i have seen have about a 2 mm to 1mm lip where it is not aligned

problem is you cant just grind it out because the bolt holes are to big and you will loose to much service area

Idea's??

IM chasing response and response only currently have 300 rwkw

with alot of torque and boost curve is about 3.600 rpm Already dont intake manifold But im afraid that making my exhaust runners larger will give me more lag ( granted it will give me more power ) but more lag anyone got info on this

[ARTZ]

the few people on here that have ported there exhaust manifold seem to be getting better response..I wouldnt mind doin it to mine,costs about 500 I think..
