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

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?

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 :/

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 :)

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

..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.

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

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
