Port match the stock manifolds. Do not waste your money on those Tomei things. I did a back to back years ago and it netted 0.000000 of 0 compared to tickled up stockers. First set cracked and the second set I blew a hole in the runner of number 1 after 1500 kms. The new ones are cast but I wouldn’t waste your money. I made 635 rwhp through a set of factory cast manifolds. The twin turbo pipe mod IS worth doing. It’s cheap and easy. It doesn’t take a rocket scientist that the angle that the front turbo is merging is retarded. When using larger twin butt plugs like GT RS/-10’s it goes a long way to reduce the infamous “choof choof” when coming onto boost. There is a cheeky mod that you can do to the compressor elbows. The factory casting has an indentation for the bolts. Fill that indentation in, grind it out and use a stud. I have posted photos of this on here. The factory piping setup really is garbage. Tight bends, small pipes, it’s all junk. 1 x vote for a medium single. On earlier, easier to work on, make more grunt, better under the foot. It’s ALL win. There is not one negative to it.

Of course the front housing needs to be modified. The wheel is different in size.

You have NO idea what shaft speed you’re at. I would bet you’re a lot higher than what you’re thinking. You’re making 560 kw on weed killer dinosaur soup. Guys here in Aus are hard going making 600 kw with e85 with a 9180. There is no problem here. I could be wrong but I’m going to outlay those cards. Report back with a speed sensor.

Spose it has to be application specific. Youre not going to run 140 lb springs on a basic setup that runs twins and will rev to 8000 rpm and you’re not going to run 50 lb things on an 8 second thing that spins to the moon with turbos the size of a small planet.

150 psi springs? Why?

Define ‘drive on’? Really, change of snails = a tune. The only driving one should do is to the tuner… using the best boost controller there is… your right foot!

Really, no one can tell you. You have to measure it up as there are too many unknowns and variables. - are there oversized valves? What size? - has the head been decked? If so, by how much? - has the block been decked? If so, by how much? - head gasket thickness? - rod to stroke ratio affects where the piston is the bore to the relation of the crank. - dome height of pistons - valve relief? How deep? So many variables the only way to know is to do it the hard way and measure it up. ANYTHING else is a guess at best. It is a expensive mistake if it’s ‘just’ off.

What are you hoping to achieve by going to a setup from 1912? what’s wrong with your setup at the moment? What are you trying to achieve by changing everything? Seems like a pretty backwards move with turbos with overgrown heavy wheels, journal nugget bearings and just general shitness.

It’s the same car.

If I dig deep enough I could find that post too… but that was circa 2009 man. 🤣.

GT - RS’s would have to be number 1, surely.

You would have been in front if you did it “back then” than if you did this last round of shit to it 🤣

Well……. After speaking about it for what, 10 years? Just do it! If you don’t enjoy it, move it on. surely you get sick of typing the same thing? 🤷‍♂️

good thread to read for twin guys wanted to put ‘billet’ wheels into compact GTR junker housings.

Why? can always put the shit lag wagon twins back on. A weekend in the garage and it’s “as it was as Nissan intended” or some other dribble that GTR guys love to froth over. As Brett said, -7’s/-9’s or if you want a bit more poke a set of -5’s. The as it’s been for the last 20 years.

I find that extremely hard to believe. A 7675 is a significantly larger snail than a 6870.

Ordered heaps of gear through these guys over the years. Never a problem.

He had vcam and removed it.

What if the turbo is tapped out and it has nothing left to give? No point running a snail at half it’s capacity. It’s too big then. 🤷‍♂️

Whatever you think you’ll spend, triple it… for a start. 🤣

Having had a couple full river batteries over the years, I won’t buy another one. They don’t last. Odyssey are even worse. Absolute trash!

Pretty sure I do mate. Let me check the garage.
