Well I was just wondering if anyone knows or has seen the guy with the tan vg that went 12.5 in the 1/4 lately. He posted some months ago and I havent seen him on the board since.

 

I haven't seen him since then and I think that was in the early spring, like March or April.

I think he has a 300zx that he runs, or some other turbo racing set up.

My theory is that he was trying to pimp his VG ECU reprogram, but virtually no one in the 3rd gen section has any money, so he had no takers.

 

hakenT i think was his name and i tried to get one of his ecu's but he stopped talkin to me...or i stopped talkin to him i forget lol

 

anybody else around here in the 12-13 sec range?

 

well, turbo vg is running 13's, i dont recall what mtcookson ran back when he had a turbo 3g, and brad92se has a trubo ve that runs 13's or 14's i think, these guys, and the guy who ran 12.5 i think are some of the fastest 3rd gens

 

I know the hakenTT from other forums and... well, lets just say I'm not sure how much I'd believe coming from him. He may or may not have a 12.5 Maxima but not many people like him on the other board and I wouldn't really be surprised if he was lying.

That's just my opinion though.

 

From what ive read of him on other forums, I agree with mtcookson

 

13.9 is pretty damn quick; im afraid of aftermarket turbos, though.

my friend's is tearing up all of the other components in his car because its so powerful, but its a saab...so go figure.

i know this dude who says his 1.6 liter NON v-tec civic hatchback does the 1/4 mile in 10 secs. i know hes done a lot of **** to it including turbo, BUT THATS PRETTY QUICK.
what does everyone else think about this? line of crap or is it possible?

 

Very doubtful- unless he has started removing body panels

 

if its built for straitline... anythings possible, yet it could just as easy be a dude just talking out of his ***. But yea it is possible.

In the end, which engine has more potential? VE or VG?

 

VG... but thats my opinion...

 

I think Tq wise it would be the VG but hp wise it would be the VE. That is on stock maxima internals. If the VG had some "minor" bottom mods then it could possibly be a better contender. But I would like to see them run head to head on the track.

 

I talked to him on AIM, to ask him which transmission he had and how itwas holding up on those 12.5 passes. When he said he had the VG trans, I told him the VE swap would get him LSD for better traction. His reply was that he has no wheel spin (with his open diff) and no torque steer...........

Since I (and most of us) can roast my tires with the LSD and no turbo, I just silently closed that IM.

 

Why do you say that? Lower compression?

 

I would guess fully built to fully built, the VE would have a bit more potential, Its 4Valve so its always going to breath better in the top end. In my opinion i think the VG would be easyer and much cheaper to built though, There are more parts available for it. In stock form i think the VG would be able to push more power, Lower compression would come into play eventually

My opinion

this isn't the "Viper eater" guy is it?? if so then....ah nevermind.....

 

The VG shares more in common with the 300ZX motor than does the VE. If the engines were left N/A the VE would probably be better...But if turboed, VG has the upper hand. (No one get their panties in a bunch, that is just a conclusion I have drawn after my time on the org.)

 

I doubt that...at the same levels if both were turbo'd the VE would still make more power since it makes more n/a power to begin plus has much higher CR than the VG as far as durability between the two, no one can attest to either being that much stronger yet since no one has pushed the limits

 

Hmm.. funny.
you guys know the VE shares MANY internals with the VG30DE?
namely the same connecting rods. both cranks are forged.
VG-E has tiny wrist pins and the first thing you do when upgrading that motor is to go with VG-DE pistons.

the only thing the VG-E has going for it is aftermarket cams available. otherwise the VE will win hands down. more airflow, forged crank, ALREADY has good rods..
stick some custom ground cams in them (not that $$ compared to building the rest of the engine), and the VE can easily put down 5-600hp if built right.

 

im not trying to defend the guy but if he were running slicks his reply would hold water

and we dont need another VE vs VG thread there are too many already but since where on the topic what the hell the VE OWNs the VG turboed as well as NA

 

Well anyway back on topic,

Why aren't there more 12-13 second maxima's ? I have mine I just got and once I get her on the road. It's on :: grins ::

 

Well mod for mod it's hard to say. If you turboed both motors and upgraded the fuel systems the VG would be able to handle much more boost because of the lower Compression Ratio, but then again the VE would spool up alot faster with it's higher Compression. They're really different motors and it would be hard to speculate how they'de compare.

 

also consider that compression specs change as the engine is built and then it gets into maximum airflow in/out, durability of rotating parts, strength of the heads, etc...

 

This arguement is alot like the RB25DETT vs. the JZA80 I mean both are nice motors and capable of alot. But can you really argue what's best ?

 

2JZ is bettter

 

the 2jz-gte stock bottom end can handle a 1000hp

 

For short periods. Not a very recommended or very reliable set up. But yes, the block is very strong.

 

No it can't.
the block and crank themselves, sure.
but not the rest of the rotating assembly and fasteners.
needs stronger con rods, beefier bearings with precisely machined mating surfaces, and stronger rod and head bolts/studs throughout.

been there, done that... watched a friend go through 4 engines in less than a year at 'only' 600hp.

 

Matt 550hp is only a small single for the supra. That engine should easily handle 600hp.

 

I spoke with a few supra forum members in person and that's what they said. Maybe there is a difference btwn the N/A, T, and TT rotating assemblies and fasteners.

 

Umm...I can find atleast three or four peope who have been running well over 600hp for longer then a year. So..umm..maybe your buddy just can't tune for ****...

 

Seasoned blocks are better to resistance than brand new blocks aswell.

 

Can you explain the technical differences inbetween the two? Thanks

 

Of course you can probably run 1000hp for years if you never actually get it up to 1000hp. Alot of the reliability of the engine is one how HARD you run it. Baby an engine that's CAPABLE of 1,000hp is different than actually running it up to 1,0000hp every day

 

I don't know the technical reasons. But in many magazines when they interview professional drag racers they sometimes mention the engines being seasoned first. Not getting a brand new block and throwing everything on it.

Maybe a possible reason is, when a block is seasoned then it won't stretch anymore. The cyclinder is already tapered and the head molds to the block better. The area of the cyclinder closest to the head will expand because it is near the combustion chamber vs. the bottom of the cyclinder where the gases have cooled off a little bit.

 

I thought a perfectly flat deck is best? I'm not sure what cylinder taper has to do with head sealing

 

Can't the VE compression just be lowered with a proper head gasket?

 

the seasoned block is considered better because any shifting of the material should have already occured.
yes blocks do have the material shift when new.
nothing new , newer blocks have less of a problem with it than older ones do

 

That would be the bad way to do it since it can change the timing. The best way would be to just get some aftermarket pistons. If most of the stuff is the same between the VE and VG30DE (rods, pistons, whatever) you should be able to drop in some TT pistons for the lower compression.

Electromotive made a VG30ET produce over 1200 hp in qualifying and run about 900 in the races. They use the stock block and heads and modified accordingly (i.e. they didn't recast the block and heads. they did recast the block out of aluminum down the road but the heads were always stock VG30ET equipment).

Being that the VE is an iron block, aluminum head engine much like the VG30DE(T)(TT) I'd say it would be capable of making quite a bit of power. I wouldn't be surprised if it could make more than the VG. If only they were used longer and in other cars there would probably be many more potential high-power VE's... which makes me think I should have done a VE swap into the Z to see what I could do with it. Maybe that'll be another project down the road.
