no no no you don't get it, I KNOW all that stuff guys :D but I love the big WHAM when it kicks in.

Oh, maybe I worded it wrong. I love that in drifting? :D

If I were to race it, I'd take an AE101 from the newer Trueno's (1998) and turbocharge it just to boost torque and maybe a little horsepower.
 
Big turbos are good on drifters cuz
1. There's no traction= high RPM's fast
2. The bottem end and the head are fully built with lightweight parts.

Therefore its great to have huge turbos on drifters

I got drift pics if u want em
 
the games engine and other physical noises are quite amazing really. on gt4 prolouge u can hear the whine of the stright cut gearboxes in the rally cars which is amazing. one thing i would like is different bov noises like sequential and other types. vetec noise is very noticible and when it kicks in there is a small but noticible increase in speed. u have to look closly for these noises though.

Yeah me too, I want to be able to buy different BOVs, each with a different sound.

very nice info...thank you! yeah the sound of a WRC is crazy...and yes the BOV sounds variations would be nice...especially different sounds at different levels of boost like the Blitz super sound BOV
 
I have two questions, one on topic the other off topic.

1. How do vtec and other variable timing engines respond to turbos? I believe the vtecs are high compression (at least the V6's). I really don't know much about vtec?

2. Someone was talking about eclipses. I was wondering which models were all wheel drive? Which of those was actually ever sold in the US? Which of those are not intensly expensive to buy and maintain? Are all Talon's AWD?

Any help would be useful.
 
lol Ok well right now I can only find this one. It's the Power House Amuse S2000 I'll get some more pics later I gotta find them lol.

at the risk of getting flamed for going off topic again, let me help u out....Eclipses come in 1st gen and 2nd gen....both are sold in US. GSX means all wheel drive and has turbo, GS-T is turbo running of the EVO's 4G63 block like the GSX. GS models suck cuz they have no power and should be taken off the road IMO :yuck: The 1 gen engine is better cuz the crankshaft is stronger than 2nd gen...thus you can do what i did and take a 1 gen engine, build it up, drop it into a 2nd gen (best if '97-'99 model) GS-T, built up the car pretty nicely, and get a street racing ticket and almost get run in for "running from a police officer."
 
1. They aren't too high on compression. Of course on ITR's you need to get lower compression pistons. Because 10.9-11.0:1 isnt boost friendly. Most other VTEC motors can handle boost up to about 6-8lbs. in stock form. Trust me I know. With rods, pistons, more fuel and a nicely ported head and the turbo @ 8lbs., you're looking at about 240WHP on an Integra GSR. Up from 135WHP.

2. The only Eclipses that are AWD are the GSX's that are turbo AWD with about 200-210HP. but AWD are hard to maintain cuz hard launches really beat the cra* outta the drivetrain. The old school Mitsubishi Starion was very nice too. Boasting a non-boost friendly 7.6:1 compression ratio, a nice bump up to 8.0-8.5:1 would bring some nice power figures for starters. I would recommend a GS-T.
 
GT4 Prologue had a massive improvement with vtec, sound and power-wise 👍

If they improve it even more for the final version of GT4,
then thats a bonus for vtec fans 👍
 
Is the GS-t AWD. Thankyou for the info. I'm not a mitsu or honda guy. More of a subie, nissan with aspirations to be a Mazda, guy.
 
ive seen some pics of the sound recording for some old v8 car and it was stand still while they had the mic up to the exhaust.

GS-T is FWD.

Ehhhh, so I guess if I ever have a decent amount of cash I'll be looking for a GS-X.

I've commondeared this thread for too long. Continue with the Vtec.

Oh I have another Vtec question. If you were all out tuning a Vtec wouldn't it be better to lock in the larger cam, or replace the heads with more conventional dohc heads? I understand the reason for having the vtec, economy and pants kicking power, but in something like a nsx, it seems like in terms of performance only vtec wouldn't be best.

Click "sound" tab.

This is from other post in here. But if GT4 in game engine sounds anything like this, then it is very promising that the VTEC sound will be more accurately recreate!

EDIT: Man! going back to listen to it again, I almost cry... u can also do them at the same time. kind of like a symphony...

There is also the 3rd Gen Eclipse, but since they aren't a REAL DSM, they don't count. And, they don't have turbo or AWD as an option, UGH!!

Actually, the turbo DSM's have a different engine than the Evo. Yes, its a 4G63, but in the Evo its mounted in the opposite direction and spins the other direction, and has a different crank, rods, pistons, head.......you get the picture. Yes, the Evo's and DSM's both have 4G63's, but they are completely different animals.

Click to expand...
None :dopey: :dopey: Seriously, those cars are money pits. I've owned 3. They can be very fast, as my current Talon is. But, they are very fragile once you start modding. Kept stock, or very minimally modded, they are fine. But, they aren't fun that way, so it gets expensive.

Are all Talon's AWD?
Click to expand...
No, just some of the TSi models. The TSi meant it had turbo, and then some of those were turbo. As I said earlier, there wasn't much stating so on the outside either. If there are no badges on the car stating either way, just look under the rear bumper. If the car has a rear differential, its obviously AWD.

Hope that helps everyone. I'm a big DSM fan, and have way too much info crammed in my head about them. Sorry for the gargantuan post. :) :) :)

The same goes for turbo and blow-off sounds in GT3, they suck...well i shouldn't say that, there not too bad, but i guess they could be a lot better. I would love to hear a solid Vtec 'vroom VROOOM' or insanely loud turbo blow-off that varies accourding to a selection of different blow-off valves.
 
Haha .. correction, the blow-off valve sounds don't suck .. they BLOW .. :lol:

.. sorry .. I couldn't resist ..
 
I honestly don't know what it is that you guys are going on about with this "VTEC sound" crap.

I'm a bit of a Honda fan, but I don't exactly rice my rides out like you guys probably do. Still... I've got a Del Sol VTEC. My brother has a Prelude VTEC. My dad has an NSX. I test drove an ITR and a Civic Si a couple years ago. I've gotta say that in their stock form, you just plain don't hear this amazing VTEC noise you're talking about on any of them.

Sure, if you really wind up the NSX it sounds great, but any performance engine with a tuned dual exhaust is gonna sound that good at 8000 RPM.

To hear you guys talk, I would think that a Honda should have some loud noise as the cam shifts, then the engine goes from whisper quiet to a deafening roar. That's just not the way it works. Sure, you can pick out the VTEC changeover, but it's not some huge difference. It's really not even noticable on my Del Sol.

Maybe this only applies to the guys who put in new cams and remove their muffler.
 
As I recall, GT runs it's engine sounds like any other game. As a very short loop of sound, sampled from the real car. Maybe a second or two. This sound is looped to provide a constant noise, and sped up/slowed down to simulate varying RPM's. I imagine it's as close as they can get using that kind of system, and is very system-friendly, doesn't use a lot of game power.

Fact is, like nearly every other GT4 question, we just don't know... No frikkin' clue what the cars are going to sound like because no one's played it yet. They may sound better, they may not. If not, it was probably a decision based on system performance. If they do, that means they've got an all-new engine-sound system that'll knock the other developers on their ass (since it'd mean the first overhaul to engine-sound methods since the dawn of video games).

No huge difference at all

but as you said you can pick out the vtec changeover

On GT3 you cant pick out anything

Prologue sounds alot more realistic.

Ditto man...'94 Black, and believe it or not, 38,0000 miles - yes, it's perfect.

BadBat I agree with you to an extent that vtec isn't as noticeable as it's cracked up to be in stock form. However with cams intake and exhaust it's two different sounding engines that I'd love to hear in GT4 once my car is modded.

lol i was trying to keep it simple for him lol...good info...my friend and i are huge DSM nuts and we worked on our cars together...im'm glad there's more DSM tuners on GTP! most people never realize the engine is reversed on the Mitsu...u sound like a true tuner, especially having owned 3! props! 👍

BIG LAG= BAD

You might as well get sequential twin turbos on it just to boost until the big one kicks in. Cuz you're car is useless if you have a huge turbo but yet can't get it high enough in the RPM's fast enough to benefit from big boost. Think before you speak. Bigger isn't always better.
Click to expand...

First of all he was talking about GT4 (which doesnt make sense already)
Second of all why would you put 2 turbos on a dinky 1.6l motor....It has only enough power to spin a small turbo....2 would be out of the question. He would be better off going to a smaller turbo like a T3 or max T3/T4 hybrid. He would instantly feel a diffrence in where the power band is. You may know alot about Hondas but you lack in turbos.
 
Just to let every one know I own a 2 gen Integra with a ls-vtec motor semi built with header,intake,exhaust,and itr cams and when v-tec kicks at 5500 rpm in first gear the front wheels will start to spin all the way to red line. Its pretty fun. My best 1/4 mile time is 13.7.
