You know what you gotta do now right? Put an RB26DETT in it!!!!

[TopGearDog]

Great looking car. I love the 300ZX.

[epp_b]

Ooooh...I'm melting...that's the best looking Z-car Nissan ever made.

[Blayde]

That's a nice Z, the wheels remind me of an RX7 for some reason.

I shocked BlaRo hasn't found this thread yet...

I can't talk though - I'm a huge fan of those zeds as well - nice example of one.

Why would anyone take a 400cc drop in displacement and a heavier engine? Especially when he can (IIRC) get 3.3 out of it with mixing and matching of other Nissan bits.

[Vambeer]

because it is THE most tunable engine around?! because you don't mess with "mixing"?! because there IS replacement for displacement?!

That would be the small block Chevy.

Yeah there is replacement for displacement, if you wanna run race gas, have shit loads of turbo lag, deal with parts never being in stock anywhere in the country, and then of course waste money on a swap that could have otherwise been spent to get more power from the factory engine.

People in the US have been getting more than enough of power out of the VG engines, I think a couple of guys have broken 300mph records with them at Bonneville even.

[Vambeer]

what are you talking about? what race gas?! What parts not in stock?! I'll admit the cost of the swap and some turbo lag but then again i'd take turbo lag over 6500cc anytime. and then you tell me about 300mph records...if i wanna break a record or something i can live with some lag. in my country we have Evo's that do the 1/4 mile in 8.5 seconds...you have the small block we (europeans and japanese) have RB26 and 4G63. different approach.

Firstly, nice Z. Ive always loved those cars, though I admit Id never touch one with a bargepole. Shame.

That would be the small block Chevy.

Id say thats debatable in all honesty mate.

...thats just not true. At all. Turbo lag is a phrase Ive heard all too often, yet never experienced myself. A friend of mines Supra runs a T78 @ 1.4bar, one of the biggest turbos money can buy. Guess how much lag that has? None. His other Supra TT, no lag. My old 200SX? No lag. My friends GT-Fours? No lag. You see where this is going?

Frankly, turbo lag is a complaint made by people who either cant set their car up properly, or cant drive. My car and my friends DC2 both suffer from more lag than the T78 Supra, and we're both N/A. Neither of us makes ANY power until at least 4k rpm. By that time, the Supra is at full boost.

Parts never being in stock, and fuel octane ratings are both irrelevant, as they apply to anything. With the internet, parts are almost always in stock. With fuel, any performance car should be running a higher octane, regardless of the cars ''nationality'', displacement, or application.

For what its worth, my old boss drives a 440 Plymouth Roadrunner. Apparently, this car ran a mid 11 in the US, backed up by timeslips, dyno sheets and several people from the muscle car club who exported it for him. He brought it with us to our local strip...it ran a 16.5. Even now, after a year of racing it almost every weekend, it still hasnt broken out of the 16s. Ive been racing there for almost 3 years, and hit some very good times. So, this begs the question, was it a victim of infamous downhill US dragstrips, or extremely optimistic dyno figures? Its not the driver either, as at least 5 of us have taken it down (I hit the quickest time I might add... ). This isnt an anomaly either. The funniest part is that the drag strip in question (York raceway) is also home to the UK V8 championship. On RWYB days, the street cars (all poxy 4 cylinders, turbo lag and unreliable race gas drinking ) are, on average, faster than 'proper' dragsters, on 95 octane fuel, street tyres, and street trim.

The main problem with the Turbo VG engine is that it is not very reliable. The RB on the other hand is close to bullet proof. Not to mention that you are getting roughly the same amount of power from the stock RB as you would with a VG.

EDIT: This is an N/A engine at that so dropping 400cc wouldn't be a problem since you are switching from N/A to turbo.

@Jlk69

what exactly does 2+0 n/a mean ? This car had a tt v6 or a n/a v6 both 3.0 right ? So what is 2+0 ?

Anyhow congrats on the car. Its a beauty, in my opinion one of the best looking cars ever. My neighbour had it and I just loved it. Though as far as I remember it was really expensive to maintain.

Dude I think you should check up on what turbo lag means. I know how to drive ( I do not have a big ego but I do have some mileage behind me ) and Ive driven turbo cars professionally tuned by ex-race drivers and never have I driven anything that did not have turbo lag. Tho I have met many many people that did not notice it or didnt care. And I find it strange that you compare n/a's delay in responsivness due to low rev range to turbo lag.
Though Im not having another of these turbo lag debates on this forum.. Nevertheless even today if you read car reviews, every turbo car is evaluated in roadtests on a scale as to how much turbo lag it has and not whether it has any or not. There is practically no such thing as no turbo lag unless its a combination of two turbos (335i) or a compressor turbo combo. Otherwise lag even if ever so small...

[Sruikyl]

Nice car, the 300 is the last good Z IMO.
and 2+0 means its a 2 seater, no attempt at a back seat, 2+2 would mean it has a small back seat.

I mentioned the 300mph to point out the VG series engines are plenty strong to take on the power, especially if you take the money you'd dump into swappng an RB26 in to a chassis that can barely take a v6 into it.

When I say "parts not available" I mean you can't just go down to the local AutoZone and order a new head gasket for an RB engine as they were never sold here.

Meh, I'm done, I'm not even completely sure got why I got all grumpy earlier. I really don't care to go on about this. I'm just sick of hearing "OMG RB26DET!" or "SR20" swaps.

That is fair and yes those SR/RB swaps for no reason are annoying. My ONLY reasoning in this is that pretty much everyone I know who is into tuning cars and auto shops all say one thing "TT is not reliable and is a nightmare to work on".

RB25DETT btw would be much cheaper with comparable power/reliability figures.

Perhaps I should have been more accurate. I used the term 'turbo lag' in the same essence as it was used in here, which is actually 'boost threshold'. Of course turbos suffer from lag, its in the nature of their design. That said, its still a heavily over-used term, and I stand by the rest of my post.

The problem I have with people saying "only poorly setup cars have lag" is that they then eventually concede and go on about boost threshold.

I don't give a damn what it's called, you put your foot down in 6th gear at 3000rpms in a t78 supra it's not gonna build boost worth a damn and it will definitely not pull like a similarly powerful N/a engine (that is built with street manners in mind of course), in the same conditions.

It's perfectly reliable, it's just not very easy to work on. Those twin turbos and requisite piping force don't leave much room underhood, so it's relatively harder to make upgrades, do silly engine swaps, etc. Lots of NA owners end up swapping a turbo motor into there anyway...and some crazy dudes end up putting LS1s in there. (Heresy!)

Turbo lag can be alleviated by improving low-end torque, usually through the headers and intake, if I'm not mistaken.

Not according to just about every other source I have heard/read. Owner of Wing's Performance (Queens, NY) for instance (who tunes Nissans for a living) stated that the biggest problem is that a part of the engine rubs on the engine bay and end up having cracks in that spot, which lead to leaks.

Pretty much every guy in my auto club (mostly Nissan guys) say the same thing, 300ZX is an awesome car but the TT is just not very reliable.
