question about skyline motors...

[absoluzer0]

So will the Rb motors fit into the 350z?

[Exar-Kun]

Yes. good luck getting it legal though. Top Secret and JUn have both put RB26DETT's in the Z33.

-Chet

[absoluzer0]

well isnt legalizing any JDM imported engine going to be difficult? SR20det for example... and by legalizing you mean inspection and stuff correct?

[Exar-Kun]

uhm..no. engines are engines, so that's not the issue..the issue lies in the ODB-2 of all Z33's that reside here. If youdon't ahve emissions regulations, you can do the awap no problem....unless you have th dough to get a late model skyline motor here and ensure it has an OBD-2 setup that a state inspector can find and plug into :/

from a state inspection standooint...I don't think many inspectors would notice that the engin was different...because they'd have to know what engine was in it to begin with. Ifnthey check the VIN on the engine versus the chassis, you'd have a problem though.-Chet

[jEzTeR]

What about states that do not VET test?

[absoluzer0]

Ok so, I live in NY, can anyone give me some good advice on how to bypass all this stuff??

[Exar-Kun]

yeah, don'tbother awpping an RB into a 350Z. Prolbem solved.

Seriosuly, unless you've got the financial backing and need to have a race or show specific car, there's no point. the VQ can be build to over 700hp for the same expense as importing and installing a RB36DETT....-Chet

[absoluzer0]

i see, Well wat are some bolt ons I can buy for the 350z to make some good power?

Sorry, im seriously a 350z newbie like crazy... please give me the names of parts that are needed to make some really good power on a 350z... aside from a turbo and supercharger. Also, wat kind of engine management do you guys use? wat are some good EMS that i can get on the 350?does this EMS work at G35s also?

Thanks

[Exar-Kun]

Greddy's new E-manage Pro is a nice peice. You can also check into the AEM EMS system.

Bolt ons are typical, and just like most engines the largest gains will always be from forced induction. I would oook into the basics first (exhaust, intake) then build up other parts to handle the power later (differential, clutch, flywheel, under drive pulleys maybe).

Work yuor way up as such and you'll be set. YOu can see my ucrrent mod list below, which has got some respectable pulling power for not a whole lot of money. Also, 350Zs aren't exactly under pwoered from the factory.

If I had an unlimited budget, I'd get a set of Nismo headers, catalsyic converters and whatever exhaust you like (I like the Nismo or Top Secret ones), a Kinetix SSV intake manifold, Top Secret intake pipe and filter, NISMO cams, a cusco dual plate clutch/flywheel, Tomei LSD..

the list goes on and on, but alas...my available funds do not.

-Chet

[absoluzer0]

actually I've decided on a G35, which i know is basically similar to the Z... But my only problem is that I currently own a stock 05 WRX, and I have beaten both cars stock for stock... I want to build a g35 that can beat WRXs first without going turbo. how much of a gain am i looking at with headers, intake, test pipes, catback

[Exar-Kun]

I've never lost to a WRX. Not a stock one, anyhow. THose drivers must have sucked.

a G35 will run a WRX out of the box. See below, taken from 2 sources, fastest times for both.

05 G35 times: 0-60 5.5 sec1/4 mile: 14.2

05 WRX:0-60 5.7 sec 1/4 mile 14.4

SO now that that's cleared up. All my bove points still stand for a G35. Gains all depend on how much you want to spend on the aprt, and tuning oyu car and such. I'd expect another 20-30hp if yopu did headers, exhaust, intake and test pipes.

-Chet

[jEzTeR]

G35c or G35x/sedan?

The G35c is an awesome car. The 03 6-speed w/ Brembo's is the way to go.

[absoluzer0]

why the 03s? i thought i heard something bad about them... forgot wat it was... or mayb that was the Z... but why would you recommend the 03 instead of an 06?

Well now, i wouldnt say that those drivers sucked... i'd just have the say that i am a really good driver...

[Exar-Kun]

G35c

I'm sure you're a great driver....

So yes...basic mods good. Perpetual understeer caused by a front ehavy AWD car bad.

-Chet

[absoluzer0]

anyway, does anyone know how strong the G35 transmission is?

[jEzTeR]

The o4+ 6-speed G35c does not get Brembo's.

If you want something new, go for a M35 sport.

[winez31]

power also depends on the brand of bolt on. i don't care what anyone says ebaybrand parts suck a**

[absoluzer0]

G35c

-Chet

which is easily countered by adding an aftermarket rear sway bar....

[Exar-Kun]

Thusly reducing your overall grip. Like a band-aide on cancer.

[absoluzer0]

Thusly reducing your overall grip. Like a band-aide on cancer.

Not really... get nice tires, and loss of traction would be so minimal... an aftermarket rear sway bar would just make it more oversteer prone than understeer which is better any day of the week...but im hearing this from a guy with an RWD car... ironic?

[Exar-Kun]

Not ironic. Logical. Ideally you'd increase your front grip to eliminate the problem. But since you've got a heavy front engines, AWD system, the more grip you put up front, the more troque will be transmitted along with the cornering forces (weight distributution)thusly perpetuating the understeer. This is better, to an extent, than simply reducing rear grip (since reducing rear grip in a good AWD system means less torque would be diverted to the back), but the problem still remains the same. Also, the rear suspension design of many of the AWD cars (EVO and WRX) leaves much to be desired.

Also, if you're pairing good tires all around, you're left with the same baseline, that doesn';t change the relevance of the thing.

You cans etup an AWD to be less understeer prone, which can be a good thing, I just believe in utilizing chassis and suspension designs for what they were meant for. Not band-aiding them.

Also, understeer is more controllable for 90% of drivers out there. Have you ever driven an "oversteer" prone vehicle? Honestly? Probably not, an oversteer prone vehicle is bloody scary to drive. A good car will react to how you treat it and typically understeer most of the time, and for agressive treatments, have neutral to light oversteer, not just oversteer constantly.

Driver ability and technique has a huge difference on chassis balance in turns also...but I digress.

It's not ironic, I'm just stating a flaw and the reasons I wouldn't buy a front weight biased AWD car in the same price range as my Z.

-Chet

[absoluzer0]

Have i driven an oversteer prone car? probably not? Good job making assumptions, matter of fact, I used to drive a BMW. Seeing as how unsafe the vehicle was during the winter time, i switched an AWD car... a WRX is actually few thousand cheaper than a 350Z and is probably much LESS practical than a 4 door sedan with AWD. Ive seen people unable to recover from understeer and ended up in a ditch off of an on ramp of a highway. I would much rather oversteer and have my rear smash into a wall, rather than understeer straight into a wall... of course depending on how close you are to the wall and how many 360s you do b4 you oversteer into a wall that is...Secondly, its true that the WRX does not have a suspension setup not as desireable, but the Evo's suspension is completely different from a WRX and is the same set up in porsches. the Evo is KNOWN for its great traction and handling... your sole decision for buyin a Z is biased.

[Exar-Kun]

BMW's are not oversteer prone cars. Not by any means. Also, I make my assumptions based on your earlier posts, and so far it appears I am correct. Since you're refering to driving a relatively high torque RWD car in the winter time as being "oversteer prone"...which doens't make a case at all, all you've done it state that a rwd car will have torque induces oversteer when traction is limited by conditions.....hopefully we all knew that.

I have driven an EVO, an STi and my 350. Evo's are a good handling car, but harder to get neutral for the points I mentioned early than a FR configuration car. Also, all the autocross EVOs I have seen have the setup I descriped (a mich wider and stickier front tire than in the back) to offset the issues they have being front weight biased and AWD.

Recoverability is easier with an understeer car because under panic breaking, with a oversteering car, it's much harder to resist the panic that most peole get, and thusly easir to wreck.

My opinion might be biased by the desire to defend my decision to purchase the car I did. But at least I have the knowledge, experience and reasoning to back it up.

My goal here is to educate you about various issues inherant to the other choices you presented, which I have done based on my own experience and knowledge of suspension design and other factors.

Also, you've got a Mcpherson strut front and a multi-link rear on the new EVO..sound familiar? that's right, it's whats on the S-chassis and many other FR cars. Now, a multi-link rear has a larger camber gain that a strut..ledaing to more lateral grip in a corner under compression..in the back....on a front heavy car......making it understeer.....

You're correct that it is a good system and on a RWD car where more torque during corner exit is transmitted to the back requiring more available grip that would be generated by the additional camber gain. On a AWD or FWD car, this leads to a bit of understeer (and even on a RWD car..such as the S-chassis, when not adjusted).....

Ohhhkay, so there you go. ENjoy.

-Chet

[absoluzer0]

BMW being a RWD, i dont see how it makes any sense that its not oversteer prone... you make good points and good for you having your experience and knowledge, but theres no reason to sound like an *** about it, which is the reason why i made offensive remarks. If that was not your intention, then you should try to take some sort of communications class.

I came in asking a simple question and from start to finish, you've been an ***, attackin the car I drive. Good job expert

[Exar-Kun]

RWD does not mean something is oversteer prone. It merely means that it is more likely to be, esspecially under throttle-exit. But that's torque oversteer, not steady state understeer. BMWs typically have mild to very slight understeer depending on the driver, tires, and model....

I was not attacking the car you drive, merely pointing out the inherent compromises the designers had to deal with when deciding on it's layout.

Also, considering you took the first stab at me (see your post with "ironic"), after I answered your questions nicely and in more depth than most anyone would, maybe I'm not the *** you think.

Had I wanted to really slam the WRx I could, much like the 350Z, EVO, RX-8 or otherwise....everything has flaws and compromises.

Once again, I'm glad you chose NICO and I hope I provided you some usefull information.

Thanks,

-Chet

[Darius]

Somebody has to chill out here. Chet is calmly responding to your newbie questions and under-educated arguments. Give the man some respect and learn from him instead of bickering at him like a highschooler. He was not attacking you, just trying to talk some sense into you about AWD vs. RWD handling characteristics. Lighten up Francis.

And to answer your RB question...yes it will fit, but it will be a very difficult swap as there are a very select few who have done it in the states and they are probably shops who keep that kind of info to themselves. If you have about $15,000 to spend on the motor and swap on top of the $22,000 car, then go ahead and give it a shot. Just remember, you'll only have a stock skyline motor after all that. The only reasons guys put RBs into S-chassis cars is because the cars are had for next to nothing (<$6,000) and the swap has been done so many times that there are parts and knowledgeable people here to help you through it.

[daggorath_fairlady]

i would love to have that engine in my ride but i like th vq35 too i guess i cannot have best of both worlds.................. i worship that RB26DETT though saw it in action....................

[Exar-Kun]

The thing is....the VQ is a increidble motor..lots of troque, sound engineering..you could push one to RB26 standards easily. Both came stock with around 280ps, and the VQ has a better troque curve.

That sia,d I do like the idea of a high-revving 10k rpm RB...but I think I'd rather have a 8k RPM VQ.

-Chet

[Darius]

Not to mention how much easier parts are to find for the VQ than the RB.
