Nismo Manifold - is it worth it?

[Sargara]

Cheers Jetpilot I'm surprised by that! Does that still apply to a GT spec with all the electric motors too?

[Jetpilot]

That is the Gt spec apparently Only quoting what i have read by the way

HR manifolds can be used as an economical upgrade on a DE, fit HR decats at the same time.

 

Would you fit the manifolds yourself or pay to get it done? That makes a huge difference to value for money.

[fake ben taylor]

I didn't think hr manifolds fit the de? Head flange is different?

 

Those saying you can't tune a z na should look up sasha anis and Michael Gardner.

[andy10v]

Abbey fit them to DEs

HR has tubular manifolds as stock which I am afraid flow real well , we have fitted a few sets of HR manifolds to DE motors with good results. We only fit these thou when we have the motor out for some work. Too much trouble to do with the motor in for the gains.

 

I very much doubt your see a 10 to 15 bhp gain from a manifold change , the main restriction on the Zed exhaust set up is the stock Cats , running HFC helps a little with flow but running Decats give the best flow but can be noisy on some exhausts , the Milltek works well with de-cats thou on the 350Zed.

 

We have been told about some other headers that do work but they remove the ability to fit cats to the car thou, they are made by

Got some RHD stock header being shipped out to them to get them to jig up for RHD cars.

 

I do feel you may see the steering column fouling on the RH header thou.

 

HR v DE (pictures stolen from the internet)

 

 

 

As far as I can read you need to use HR decats or HR cats with HR exhaust manifolds on a DE.

[-G-]

Save your money, the headers will help, but for the price its an expensive gain, same goes for the plenum, AFAIK the Kinetix is intended for FI really and wont make I big difference, better off with a plenum spacer IMO.

 

You can still attain 300BHP or close with decats, exhaust and plenum spacer with a remap.

 

^^^^ This all day long. Easiest way to reach 300bhp from the DE.

[-G-]

Just fill the car with helium balloons!

 

Helium is more expensive than petrol! 200bar cylinder is upwards of £4000.

That's brilliant news on the hr headers!

 

The ppe hr headers are a better design than the de ones. Wonder if they would also fit?

 

Fwiw guys, after the usual breathing mods (spacer, filter, exhaust, decats), on a rev up just adding long tube headers (like ppe not dc type) should see you break 300hp at the wheels.

Earlier de cams aren't as aggressive so sadly there's no gains with headers alone but headers and cams will see near 320 at the wheels. A few other little bits and near 340 at the wheels is doable.

 

So taking revup. You're looking at £1500 for headers (after the usual bits are done) for not far off supercharger power.......

[fake ben taylor]

Sorry. 1500 plus a remap

Cool story bro, if it costs £1500 to get 340bhp, why has NO ONE else on this forum got that?

[fake ben taylor]

No one has ordered long tube headers...

 

Sasha anis detailed it all. There's magazine articles, my350z where many have now done it. Look up 'on point dyno'

 

 

Maybe a lot of the reason is that every na tuning post on this forum is shot down with 'its a waste of money' or 'just go fi' etc with no one actually having done any research into na......

 

Ppe are the only manufacturers of long tube headers for rhd cars and when I spoke to them they'd only sold two sets to the UK. One set I know of is on a early de so wont see the gains without cams as well.

In America there's Ppe and what was sgmotorsport headers (but sgmotorsport ones are now made under license by someone else).

Sorry buddy, if it were as simple as a set of long tube headers/rev up cams and "a few other little bits" to see 340 rwhp the world and their dog would be doing it and it has nothing to do with people shooting down na tuning, even the specialists tell you your wasting your time.

[Tricky-Ricky]

Sooo..... 340 bhp at the wheels would mean taking into consideration drive train losses, would mean a minimum of 380bhp at the flywheel.... :lol:

The world is doing it.... Just not the UK.

 

Don't want revup cams for the 340, need some very wild ones, like jwt c8 and above.

 

But thank you all for highlighting why no one on this forum tunes na.

Rather than approach it with 'interesting, no one here has managed that yet' you ridicule and shout it down.

The 'specialists' in the UK haven't really tried the right mods in the UK yet to get power.

Before ridiculing read this. This is sasha anis who documented every step all over my350z and has replicated the results on other cars. This is just a handy reference. Notice how he said high comp and forging added zero power as it wasn't the bottleneck? That's why no one in UK has managed power na yet, no one's taken the right path.

Your maths is right, i.e. 340bhp is achievable with internal parts changed.

Your pricing is completly off.

[fake ben taylor]

Interesting also on those graphs to note where peak power is. He was revving to 8k as it makes for a quicker race car but for peak power he didn't need to rev much past 7k

My pricing, if you read what I said, was for near 320 on a rev up.

 

That link I posted is all on a de. He added headers and a freed up intake to a revup and broke 300atw straight away.

Out of curiosity, how much would changing the cams

I wonder how much long tubes, cams, head porting and ITBs cost including fitting?

£3/4K+

[fake ben taylor]

Itbs are mega ££££ and need a stand alone ecu set up.

Everything up to those can be done with revup remaps

 

Cams are £900 a set Inc uprated springs I think. Not sure on fitting, I aim to do it myself.

Headers are 1500 from ppe for stainless, less if you go mild steel. Available through Torqen.

Remap, not sure on prices on these but can be done via revup.

For the big numbers also need larger throttle body (I'm designing a cheap UK based kit atm), modified inlet plenum, larger inlet pipework, gtr injectors, Walbro.

[Tricky-Ricky]

Its not shooting down, its common sense! if you read through that link it has 300deg duration cams, and ITBs so all the valve gear would need changing, and I would suspect piston cur outs for the lift, new springs retainers, you would also need to increase the rev limit to actually use that cam profile, so more strengthening needed, add to this extensive porting along with a really decent map (would the std \ECU be suitable?) so maybe stand alone, plus dyno tune time, you could certainly spend 20K doing all that, which is why you don't see a lot of highly tuned DE N/As outside tuning shops.

Its basically cheaper to add a supercharger kit or turbos to get more power, a no brainer to me.

Compared to about, £4-6k to install a Vortech kit on a revup for about 440hp?

Yup, and not even sure if my estimate would inc fitting to be fair.

 

I'm not against NA tuning, I'd love to do that to mine. Just didn't like the fact that someone thought you could throw £1500 at a car and get 340bhp
