This Manifold Vs Stock

[zebra]

Ash - The Mafia has/had 320rwkw or something with a .63 I/G 3076 on the stock manifold, did have WMI though

Not interested in changing the turbo atm, just looking to make what i have work.

I was hoping for over 300 but if its not going to get there then im thinking i may as well go back to standard.

what is WMI?

water methanol injction

Have a look through the rb25 upgrade thread for results with stock manifold e.g.

#625 301kw

#643 334kw

#662 303kw

log style manifolds are crud

try and find a hks cast low mount manifold. They look stock enough

But then all the intake and dump needs to be made again as it dosnt put the turbo in the factory location.

I guess your stuck then between stock and the chinese crap.

I dont think its even possible to have a nice collector/runner in the stock position

[Adriano]

^^^^Exactly, thats why noone makes a good one for factory position

But lets just get back to the requirements at hand for a second…

1. Tight budget – so clearly no $1400 manifold manifold, custom piping, new dump etc

2. As factory as possible appearance

3. No more than 300rwkw

As to wether it’s the best performing setup, giving the best performance etc etc - really is not the question or issue here at all.

So who cares of its “crud”. It’s been proven to work & the stock manifold fits those requirements perfectly.

How much difference have people seen between something like this vs equal length runner?

[gotRICE?]

Lithium is making 300rwkw on a stock manifold with a 3076 .82 internally gated on a 200,000km motor.

Seems to work for him, and drives as smoothly as my 77,000km motor.

He had one of those exact manifolds on his for a while. I think he got it for quite cheap so tried it. Made the car sound pretty awesome, but blew the welds at the flange after a while so went back to the stock.

I think it had something to do with this:

lol

[Lithium]

Wow I forgot how slow a ramp rate that old dyno was, no wonder my car went from making full boost at 3500rpm to 3700/3800rpm lol

Least you know the tune would be spot on for WOT in 5th gear haha

How much of a difference was there, both on paper and seat of the pants?

[Lithium]

Seat of the pants, basically none - which actually surprised me. The most power I have made on paper was with the stock cast manifold I put back on after the stainless one failed. It SOUNDED like something more serious with the stainless manifold though, which gave an unjustified sensation of speed.

Lol all this talk about 3071/76/35r....

he wants a high flow or a 2530?

Stock manifold is fine...+ heat shields + factory EVERYTHING = you get to smile when you get asked to pop your bonnet..

It pays to read the whole thread, the first post was 5 years ago, i chose to bring it up again as it has relevant information and was interested to see if there has been any definitive answers gained in the 5 yrs since this was posted, its also relevant in that its the exact same manifolds being talked about today as it was 5 yrs ago when the thread was posted!

I dont know the guy who started the thread i spose...
