300zx..

[KlutCH]

I was just wondering does the 300zx come with turbo or only with twin turbo..i know there is the non-turbo but i was just wondering..thanks

[aznflick]

Twin turbo only! never came out with single. thats why they have the engine code VG30DETT the TT stands for Twin turbo.

[Tommy_Kira]

the TT is dandy. but the spool time in my oppinion is ****. some people say it dsent matter..but think about it this way. how do you make a TT supra faster..Take off 2 turbos and fit on 1 big one. but thats also in inline engine. API just came out with a single turbo kit for the 350Z. and its supppose to blow GReddy out of the watter. iv seen 1000HP RB26DET's..also 1000HP RB26DETT's...for some reason HKS knows how to make the TT RB engine book it. but like it said. spool time. its not everything. but its alot.

[H22DC2]

i like the single turbos myself not a fan of the twin setup.

[Tommy_Kira]

have you ever driven a TT car? LOL . its a joke you mash the peddle down and wait...and wait..and wait and somewhere near 5.5-6K RPM you get boost. then you shift at 7.5-8 depending on the car..and fall back down just below the spool point. besides the R32 i think every TT car iv driven has this problem. the RB engine has exilent responce. because the choice in turbos..if you slap a boost controler on it and take it above 8-10 PSI...you have turbo parts flying out of the hood. fin breaks,into the intake mani. down the hole sticks open a intake valve, piston kisses the valve..sucks it down in. boom...bye bye GT-R. single is FAR better in my oppinion.

Huh???

That makes no sense. The whole point of two smaller turboes is for them to be able to spool up faster. Something must be wrong with the TT you drove. The VG30DETT and the RB26DETT in the R32 have the SAME turboes!!! The compressor housing is clocked a little different on one of them. They are completely interchangeable. Our Z spools by 3500 and has larger than stock turbos. And they spool a little slower than the stock ones did. And as far as the 8psi turbo explosion... I'm running 10-11 psi on my stock turboed RB and sometimes run 14 psi... No exploding turboes here

As far as the fins coming off of the Nissan turbos, that is on the ceramic versions and it is the exhaust wheel... overspin turbo, ceramic wheel disentigrates and blows out exhaust pipe. Ask me how I know. Because I did it on my first RB turbo, oh and it was a SINGLE!

In answer to the original question, yes there is a single turbo 300ZX. From 1984-88 they made the Z31 body style 300ZX with either a VG30DE or VG30DET single turbo. In 1989 they came out with the Z32 bodystyle and it is available with a VG30DE or VG30DETT twin turbo. Even though they have the same engine designation, the two body styles have different engines and are not cross compatible.

ive always had the same idea or thought on the spool time, only because it has to do with more piping, elbows and such (one technician said taht straight piping is the best for airflow and non lack of wasted time), having more piping , even though trying to save space is traveling through more passages. - just an opinion

[nismoron]

That is true. But per turbo there is not any more length than with the single. On a twin turbo 300ZX you can treat it as two seperate 1.5 liter motors. Each side has it's own turbo and intercooler, so there is not twice the pipe length.

The larger the turbo the longer it takes to get it moving.... its called inertia. To get a larger single capable of flowing the same air as the two smaller turboes, you WILL have to give up some sppol time. As the exaple above, the Skylines with the large single can make extremely large hp numbers, but it is at the expense of lag time. They make up for this by putting in stronger valve springs, titanium valve retainers and higher lift cams with less aggressive slopes on the profile. They then move the rev limiter up to the 9500 to 10,000 rpm range! They do this commonly on drag cars, but if you look at some of the circuit and time attack cars where throttle response and wider power band are more important.... They use a couple or HKS 3037's or some TD-05's or 06's

[Tommy_Kira]

i agree with just about everrything you said. but the TT 300ZX stock has horrid responce to say the TT supra. or the TT RB. both cars have AWSOME responce for having 2 turbos. but i guess i should have made my self more clear. i was talking about more track application,rathern than drag. you dont need 1000HP on the Tskuba,unless you have somthing to stick it to. i think 1 decent turbo with awsome responce and no lag is the best. IE. the HKS hypermax EVO...or the CYBER EVO...they wipe the floor with alot of GT-R's..cause they can put down a mid amount of power and make it stick with no lag. and as far as the stock RB26DETT turbos. on the GT-R 33 they had problems with the exhuase side like you said,only when the compressor wheel got ****ed sidways..it broke off a intake side fin. they almost never made it threw the intercooler and throttlebody..but it did happen. i was stating it as a possiblity. not like crank walk on a2G eclipse were it happens all the time.

Are you out of your mind?

Sounds like you've never driven an S4, RS4, or 911 turbo.

I have 25+ psi by 3000 RPM with almost NO turbo lag.

[Tommy_Kira]

nope...never had the pleasure. im not say that TT is the wrong way to go...im saying that alot of STOCK TT's do have alot of lag. also...look at the FQ-400...1 turbo and lag..alot of cars have lag...its just more Stock TT's have more lag than stock singles. but when you build them...you can make that change alot.

I still don't buy that. Most of the time, the purpose of a TT system is to REDUCE lag over a single turbo. Here's a dyno graph of a stock Audi S4 and an S4 with an APR chip (weaksauce). You can see how strong the torque is (especially for a 2.7 liter) even at really low RPM.



Other TT cars I've driven with little to no lag are Porsche turbos, Mitsubishi 3000 GT, and an Audi RS6.

[Tommy_Kira]

i cant find the site. but it was a nissian 300ZX torque curve over a supra. it was much less powerfull at low RPM. and that was my case in point. but yes your very right audi rocks the TT. the twin turbo kit for the 350Z is also very low on lag (turbo choice) and also its a V engine so you can treat it as two seperate engine like said befor. but the new API single for the Z has next to no lag and its more powerfull. ill get dyno charts to prove it when i get back to my house so you can see what i mean. i never said anything about the porche or audi turbos...theres a reason why they cost in acsess of 80K$$$ and i lied. i have driven a porche 996 bi turbo and i dint even know it was one...thats how little lag there was.

Single turbo engine code for the Z31 was VG30ET the VG30DET is a single turbo version of the Z32 TT motor came in some Japanese turbo sedans and such.
