I smell a challenge coming on
Ve-t vrs vg-t
can someone still get a hold of that guy.

 

Oh oh.... I like the idea of this one....... BTW 4signs..... Any plans on making a kit for the VE's ?

 

been thinking about it. I would like to do some more R&D before I would put one together. Im leaning towards just fabricating the pipes, unless there is a big demand for a kit.

 

I know of a great spot and have access to a few DV cams for uploading online/editing. Hmm..

 

I have a few more pics of his car somewhere I think...

 

I put my money on the VE...mad top end power. You better not spin out of the hole though, or the VG will put a little on you

 

I think the VG may be able to have shorter coolant lines. It also seems to me like maybe the VG might be able to take more boost. It would have a better power-to-weight ratio, wouldn't it? The VE has that top end, though...

I have to admit I never thought anyone would actually turbo a VE. If this isn't the first, it's certainly the first I've heard of. So very, very impressive...

 

assuming both engines are in excellent running condition, totally stock internally, same turbo and boost levels, it would be a tight race. The VG would pull off the line harder, as they tend to make more torque, but the VE pulls at higher RPM. It would be close..short race to the VG, more than 3 gears go to the VE topping out. It would be interesting race to witness.

 

if the VE is a 5spd it will take the VG off the line....good ole VLSD will allow it to hook much easier. after the laucnh though its anyones game, there are many other factors to consider aside from the VE having "top end power"

 

I see how you are basing your decision, but a stock VE 5 speed vs. stock VG 5 speed...the VE will pull off the line and continue to pull...so stock boost, levels,etc...should be the same outcome.

 

what about piping lengths and bends(or the entire setup as a whole), pressure drop, fuel system effiecieny(one car might be running lean or rich)...just popping turbos on cars and saying this should be the outcome doesn't hold much weight IMO....there are other factors to consider.

 

oh god, here you come now I was making the same decision he did...

 

Even w/ the same psi, the two engines will react differently. I'd generally say, whatever race outcomes for na, will be just about the same for turbo.

But the VE is much better equipped to move the air than a VG. 4 valve heads, varible cam timing, "maybe" a better intake manifold design, direct on coil ignition etc..

But honestly, it's probably who ever designed their system better because right now, there is alot of ghetto systems and maybe 1-2 nice systems. But that's how it is for the 3-gens at this stage. In time we will see some better stuff.

 

thats my whole point...but I didn't know how to put it as eloquently as you! IMO its gonna come down to design and efficiency not NA 1/4th mile times.

 

Mine went from ghetto to semi-ghetto .

 

Hell yeah, tell him whats up Jeff. What do you have to say to that???

 

no more aluminum foil rolls??

 

I agree totally..it's all about whose system is better designed and tuned. I have a friend who turbo'd an NA eclipse running 6 psi..that thing is a turd with turbo hiss. Once we get a few turbo 3rd gen's built, as it seems there will be several within the next year or so, we should settle this at the track. DA-Max is right..the intake piping from the turbo (and the IC installed) as well as the exhaust piping leading to the turbo will make significant changes in behavior. No doubt the modified Y will work fine, but a manifold that puts the turbo at the engine is definately a better design. Also, keep in mind that skipping the IC is better than routing all that piping to and from an improperly chosen IC.

 

i think the vg would do better. it's built for a turbo unlike the ve. but, only a test would show the truth.

 

In exactly what way is the maxima na VG engine "built" for turbo? Yes the VG Z31 turbo motors are purpose built but when talking about a maxima VG and VE, I think they are both equally capable. Both feature iron bocks and both haven't exhibited any abnormal HG failures.

 

most people are just getting the z31 engine or using it's block therefore making the engine they are using built for boost unlike the ve. i'm not saying the ve can't handle any boost i'm just saying the ve wasn't built with the intention of putting a turbo on.

 

neither are built for the turbo, witht he exact same setup etc. theres no doubt in my mind the ve would pull away.

 

Really? I would think the VE would have the advantage. More air moving in there... depending on the setup, of course. There's no doubt in my mind, however, which would be more reliable. The VE IMO is a lame duck anyway. Damn VTCs

 

They put doen relatively big number, , but the few that start to jump into the range of 350+ they start running into serious transmission issues, even the built trannies start coming up with serious problems, but like you said most of them stem from torque.

 

the z31 turbo engine (which seems to be commonly used when doing the swap) is built for a turbo, that's why there is one on it

 

A lame duck that'd rip the **** outta yours so therefore.. VG = ..?

 

*DOH* what i meant to say was, there's no doubt in my mind the VE WOULD pull away.

 

The VE would definitly own the VG. Given basic intake, 3in exhaust, 10-12psi the VG would be around 205-215whp/250-270tq. The VE should be around 220-240whp with the same mods.

 

what about torque though? the ve really lacks low end torque whereas the vg has awesome low torque. add the turbo then you have isane top end. with the low end torque you could get the ve off the line then with the turbo you could pull away. the ve would probably just get all topend and not really gain any low end torque. we need dynos and some track times...

 

That might be "partially" true if you started from a roll @ 1,000 rpm. But when is the last time you did that?
Use a small turbo and the VE will start boosting as low as 2,300 rpm. Ask me how I know And w/ the ability to process the air w/ 4 valves and varible cam timing, guess what happens?

Ari, I agree on those numbers. W/ just 4-5psi, I estimated the power at about 240hp at the flwheel. Maybe 250hp. When I drove the 2k2 I30, it felt like my car on boost.

 

do you say that because you know what your car feels like on boost:evil:? or do you say that because you're hopeful thats what it'll feel like on boost ?

 

What? ... I guess so... whatever you say. The VE is a lame duck. That's why it had such a brief life, and now there's the VQ technology.

I'm not making a debate on which is faster. But there is no debate on which is more reliable. Besides, I haven't had a VE match me yet. Sure, there's plenty, but to say my car is slow or even slower because it's a VG is ignorant. In a battle of reliablility, though, the VG gets it hands-down. I do think that in most cases, however, a boosted VE would be faster. That is what I've been saying, so drop your defenses, pal, and enjoy your lame duck.

 

Lame duck? Ummmm...the VE was stopped in production cause it costs so much to produce, therefore the cheaper costing more refined VQ was made. How is the VG more reliable? I have 257k and still rip azz.

 

Ever had problems with your VTCs or crank angle sensor? If not, you're an anomoly. The VE seems to have all the problems of the VG, with the addition of a few extra extrememly expensive and time consuming repairs. Powerful, yes, but I hardly see the argument in comparing the reliability.

 

Crank angle sensor? Never heard of anyone having those problems. Remember VGs have injector harness problems and hose leakage problems at the injectors. VEs don't due to it's side feed fuel rail.

 

very true. I personally have been fortunate enough to never have had any injector problems, or even hose leakage. The only issues I've had with my engine have been cooling issues and blown head gaskets, but I'm pretty sure that was just from nitrous abuse.

I still stand firm in my belief that the VE would take the VG in a race, even a VE-T vs. VG-T, but I also stand by the belief that the VG-T would be a more reliable beast. Small descrepencies in set-up may make less of a difference than you think. After all, it is all about pushing air, right? There's no doubt that the VE has that advantage.

 

hey you VE guys...where's your PCV valve? LOL

ok this thread is getting a little out of hand here.

there are fans of VG..
there are fans of VE..
pros and cons to both motors.

 

Ok, where's your oil filter. So who's going to have the honors of taking care of this thread?

 

What do you think?

 

gut feeling tells me hes boosted. logic tells me hes not(no threads claiming boost..actually, thats the first mention of jeff being boosted ive seen). which is right?
