Hey all...

Just wondering an opinion on something. I was just wondering what you thought was faster on the 1/4 mile...an Evo IX with about 325whp, or a Turbonetics 350Z with about 390whp? Just wondering because someone made me a killer deal to trade my evo for MSRP and then i would go get a 2006 250Z with a Turbonetics turbo kit. The kit produces about 500hp at the crank, 400 at the wheels with 8psi. I love the whiplash i get from my evo everytime i throw down the throttle anywhere from 0-40mph, and i'm afraid of upgrading to a car with N/A 300hp already, the power band will be super smooth. I'm not necessarliy looking for the FASTEST car...but i want one that kicks you when you throw the throttle down. I figure that the 350Z running at only 8psi would last long than our evo's running at 20psi...any thoughts on that? I want the car to haul ***, but be super reliable...and i know that our mitsu's struggle there...anyone know anything about the 350's with a turbo on them? any imput would be sweet. Thanks

 

what else is modified in the 350z engine to reach 500hp?

 

Nothing...it is a straight up turbo kit, with only the turbo, some injectors, FMIC, piping, and an air filter...that is about it. It comes with BOV and wastegate too, but no internal engine work. It is an amazing kit

 

What do you mean you got a killer deal to "trade" your Evo for MSRP? What does that mean? You can't get MSRP for a used car...what the?

Then, are you saying they provide 2006 350z's with Turbo kits from the factory or something, or are you talking about buying a new 350z, then paying to add a turbo kit for about 8 grand? What I can tell you is that if you think a turbo'd 350z with stock internals while trying to push 400whp is anywhere near as reliable as an Evo, then you are on crack. The Evo engine is INCREDIBLY reliable, because it already has forged internals capable of handling upwards of 500-550whp. When/where did you get this idea that Evo engines were unreliable? Were you equating reliability of the clutch and/or drivetrain with the engine? Those are 2 separate things. I can't imagine you'd expect a stock 350z drivetrain built to handle 230-240whp in stock form to hold up well after adding 160-170whp on a 2wd platform. Has any of this crossed your mind?

Oh, and to answer your question about which one would be FASTER in the 1/4-mile, well let's think about it. 390whp...325whp...similar weight...hmmm. Let me ponder this one for a few seconds...well duh, I hope my sarcasm shines through. 65whp more would be much faster in the 1/4-mile. Whether or not it's quicker would depend on tire selection and driving ability. I raced a turbo'd 350z with over 20k spent, including a rebiult/fortified engine (blew his original after the turbo). He ran 12.3 at 117+ mph while I ran 12.1 at 111 mph pretty much all day...

 

i think even the greddy team has only bested a 12.4 at 115 (or something like so) with there twin turbo kit stage 3. 350z look very kul, but you will never reach the power and reliability of the evo with a 350. on the freeway 350 would rock with 400 whp but take 50-75 whp away from evo and would still kill a 350 at the track.1/4 mile that is

 

Well, how do i get to about 375whp? My following mods and some 272 cams? (when they get invented)...the only thing i'm afraid of is that my car will idle roughly...will a flash eliminate the rough idle and make it idle like stock still? Warrtalon, help me out bud

 

My buddy has a TT 350z. It's a super fun car but I'd rather having something I can drive in the rain & snow.

I dont think the z engine (better said renault engine ) will be reliable at 500hp,without internal modifications.

 

EVOIXOWNER,


I buy a lot of car magazines all the time. Not long ago they had a car magazine in which they tested 5 350Z, two of them turbo, two of them S/C and one stock.

To be honest, the 350Z really, really sucks on 1/4 mile time. They DO NOT respond well to a turbo and S/C on the 1/4 mile however they do make good power.

APS and Greeddy have nice TT configurations on their 350Z but in reality they are very hard to make them run below 13 in the 1/4 mile.

I would like to say Evo 9 and not because I have a Evo 8 and a Evo 9, because I have not seen a single 350Z TT or S/C with any impressive 1/4mile yet.

Here at the local track(SIR) Tucson I have seen two 350Z but they ran 15.5. I ran a 98 Golf GTI VR6 yesterday and did a 15.7.. you know what I mean?

 

Well, first of all, hopefully you don't think you have 325whp right now. Secondly, 375whp is quite a lofty expectation right now when you don't seem to know anything. You are talking about 272s, but we don't even know if there will be cams. There may be _A_ cam, but we don't know. We also don't know how much of a gain there will be from cam(s). The tuning flexibility we are seeing with the new ECU may already be taking advantage of cam changes, so there may not be a lot to be gained from a cam(s) when you're tuned for it (flash, not SAFC, which is not good enough for the IX). On the other hand, we may find that a cam(s) will put the IX into the 350+ range on pump gas with basic bolt-ons (intake, exhaust, mbc, tune). We don't know right now, so you'll have to wait and see.

On an 05, to get 375whp, you'd have to have all the bolt-ons + cams + alky injection + alky-specific-tune. That doesn't require any change to the internals and is still reliable other than the alky maintenance (refills). Idle lope can be mostly tuned out in current VIIIs with a tune and/or with cam gear settings. I'm not sure why you'd be so deathly afraid of a little idle lope...it's not like the idle suffers...it's actually a cool, menacing lope that advertises how badass your car is. In case you're just completely opposed to any lope, I can tell you that I have a close friend with a GG MR like mine who has straight HKS 272s with no noticeable lope due to his -4/-1 cam gear settings.

 

Thats like the exact set-up i would have...how is he liking it? You said you have been in it...does it throw you back super hard when you accelerate from 0-40mph like the EVO? It says that he has all stock parts...how is it holding up...do you have a site i could contact him at?

 

500HP on a stock 350Z engine is asking for trouble.

You'll probably have to rebuild the engine in a year or two.

Not worth the trade IMO.

 

From 0-40, all you would do is spin. Why is this not inherently obvious on a 2wd car with 400whp on street tires? This will throw you back in your seat from 50+ in 3rd gear or higher...

 

I dont agree with a 350z turbo being more reliable than a evo even only runnig 8psi of boost. Keep in mind 8psi on 10.3 comp ratio motor is high on stock internals that are made for a N/A performance. Yes, tuned correctly it will be reliable but not any more than a evo IMO

Keep the EVO!!!!

 

Here's an idea, keep the IX. Get an AEM EMS, HKS 280 I/E Cams, TB Exhaust, MBC, FMIC+Piping, BOV and possibly some Alky Injection. This is the route I'm going before I upgrade to a GT3065/GT35R. Also, since you already have a IX turbo, you could upgrade to a Buschur Racing 20G-9 Turbo for pretty cheap. This turbo looks like a great option. Screw the Z unless all you want is some poontang.
