Yeah I like that torque number as well, its like a truck.

As far as gear boxes go the stock one is a big stong one, but yeah they are big numbers we're talking about. Time will tell. (Hopefully whoever Time tells will a member & post the info )

 

It was Nizpro that posted some info here. IIRC the claim was at the fly on an engine dyno (as seen above) so the 393 must be at the wheels. They're pretty impressive figures either way.

FWIW they never answered all of my questions but I did a few calculations based on what I'd do and came up with a figure of $33k ex labour. That covered the turbo setup, rods, pistons, cams, ECU, clutch and various valve train and misc parts.

Sounds like you were pretty close.

 

Yeah but there's not $12k of labour in the install so either I'm missing something or they're making a nice profit.

 

you can really take off with that sort of power already! That's awesome!!! Power.... we all need more power!!!

machapman is correct, if we are all after huge big power, we would have not come to this forum, but in skyline GTR forums already.... well... as I know, the RB26DETT is a VERY strong engine which can take over 1.0bar and produce 400 HP easily without too much mods/money!

But it is hard to give up the zed because it just looks so sexy and drives so smoothly, that's why I have a second thought about the engine conversion to the Nismo one, but heard that it will be a huge investment if I am getting a BRAND new engine... might be good to look at just swapping/re-enforcing the internals and still stays N/A. I will be A LOT happier if I can rev my motor up to 7400 rpm just like I used to on my m3... the extra 900rpm shall give you quite a lot of differences in terms of acceleration (don't need to change the gear that often to reach 100).

So does anyone knows how to raise the rev limited/fuel cut off safely? what should I do and how much am I looking to spend to achieve this result?

cheers and thanks in advance for any input!

I can say what info i've gathered but its based on my own info, other peoples info etc.

Well increasing the rev limiter is easy, either:

ECU Reflash - ~AU$1000(If you use the powerchip one)
Motec - AU$3500

To rev to 7300rpm (or 700rpm more) productivly ie pulling all the way to redline, you'll need:

Connecting Rod Bolts - for strength US$20 each (X12?)
High Lift/Duration Cams - US$1100
Intake Manifold - ~US$400
Air Filter - US$120
Extractors - $1100
High Flow Cats - US$550
Cat Back - US$800

Keeping your redline @6600 its good for 200rwkw,

but you will loose torque down low if you get cams that take the peak to 7300rpm. That is where the trade off is, you might be better just increasing to 7000rpm with some lighter cams so you dont loose that bottom bit and still get good up top. It depends if you want you'll be doing more of, racing ie high reving all the time or daily driving ie starting and stopping etc.

Check this for similar examples:

You could probabally do it with just the, Cams, Bolts, ECU Flash, but the engine is already being starved a bit at high rpm so some of those other parts are needed as well to reduce any bottle necks in the system and to get good gains all the way to redline.

 

cool man!!! thanks mchapman! Those things are all available from Nismo and I guess it might be good to just go up to 7000rpm... and most likely use Uni-Chip to get a light tune on the fuel/air ratio, which will improve some high end power as well!

Where is the limiter set for you guys??? I'm sure that mine already goes to 7000 before fuel cut-off. It was one of the first ones out. Was the first round of Zeds set higher?

No I bought mine in April-May, it should be 6,600rpm. Next time your in the car rev it all the way out and see.

 

I got mine on 14th of Feb 2004.... it will be exactly one year on this Saturday!

I revved mine up to 6600 and the needle was already bouncing up and down at 6600 and I needed to change the gear before the engine had nothing to burn... so I am quite sure it is at 6600 not 7000.

This baby is a VQ30 Twin Turbo. Found the same pic on the net.

 

Near enough

Which brings up an idea. Just how different is the Z32 engine? Would it drop right in? For that matter could the exhaust manifolds be swapped over? Cheap turbo conversion possibility?

 

NFI But I doubt we have that much room for the turbos to stick out like that, I bet our turbo manifold would have to have turbos closer in and down more probabally?

But if you wanted to drop an engine in the RB series is supposed to fit I think... Well I heard someone trying it.

 

The RB would require some work to fit. I was just wondering as the VQ30 is basically the same engine isn't it? I have no idea. Never really had an interest in Nissan before.

 

Sure looks different but I have no idea either. The VQ30 doesnt have CVTCS etc, and it has a cast iron block with two turbos

Anyone have any idea?

 

I thought the two were very closely related. Could be way off the mark though.

 

They are related, but the VQ30 is from a performance background where the VQ35 was originally as a maxima engine. The VQ35 was made to be reliable, smooth, light weight etc and it just so happens that these are the same qualities that you would want in a performance engine as well. Hence people racing with VQ35s etc.

The Aluminum block in the VQ35 cant take the same power levels as the cast iron block of the VQ30. But the VQ30 doesnt have all the new technology that the VQ35 has, Molybendium coated pistions, microfinned internals, CVTCS, drive-by-wire, tuned exhaust etc etc

Should a new post be made to get peoples info?

 

Probably not worth it. I'm sure if it could be done someone would've done it by now.

I was under the (unresearched) impression that apart from the bolt on bits and materials the engines were the same and that the VQ35 was essentially a VQ30 with a bore and stroke job to get the extra displacement. It's unusal for a company to use a similar designation for unrelated engines.

 

I got the info in the first para from an article I read a couple months ago written by a Nissan person. And im basing the aluminum block info from a RB26DETT whos block is also cast iron block and can reache phenominal power levels.
