single turbo conversion vr4

ok I have a 94 3000gt sl stock with stainless header
1. I can do all the tig weilding and fabbing myself/tube work.

does any one know what single turbo/psi
I could use with a stock vr4 ecu/injecters/fuel/pump
without tuning or damaging my sl motor ?

2.or a website that shows how rare 3000gts are by color and year/model

what single turbo would match the 2 stock vr4 turbos?

Quick question, why are you going to all the trouble to go to a single turbo? There is really no reason for it at all.

stock vr4 hardware looks like shit and is hard to get to .
plus if I have one turbo away from the engine it will stay alot cooler with my cowl hood

I realize beauty is all opinion, but you can get prettymuch anything under the hood in chrome or powdercoated form...from intercooler and intake plumbing to valvecovers and manifolds. And it's not that hard to get really. Just look on a partout thread on 3si.

I dont think you have a clue.

Have you ever seen underhood pictures of single turbo 3s's? They are just as crowded as a TT.

If you think parts are hard to get to, how do you think you are going to pull off a single turbo conversion?

I meant hard to get to to service .not hard to come by.
I hear exaughst leaks hapen alot around
gasket areas with any turbos on any vehicle.
I just want to put one one the left hand side of my motor I just bought a
nice fiberglass hood with air induction and If the turbo is away from the engine it should stay alot cooler than two hugging the motor.

What I was saying is if you think its difficult to get to parts service parts then why do you think you can pull off something as difficult as a single turbo conversion?

How the hell are you going to put a turbo on the left side of the engine? There is no room.

Also exhaust leaks are only going to happen with age. Its not something that is going to happen once a year. I had a turbo DSM and had the turbo off about 6 times, reusing the gasket every time and never had a leak.

Stick with the twins. Doing a single conversion is not for the faint of heart. There is a lot of planning needed and many modifications required to make it work.

well theres plenty of room on the left hand side and thats were its going to go!
fab work isent a problem I have a full shop and a auto salvage yard 500+ wrecks and a few vr4s for parts !
I dont know alot about turbos just the basics that why Im asking!
what single turbo would match the stock twins without tunning
a stock vr4 computer air /fuel mixture

People go single to go big. THere is no point in going single to match stock TT's airflow. It will be a huge waste of resources.

Again there is NO ROOM on the left hand side. The left side is the drivers side.

Theres a reason single turbo 3000GT's are few and far between.

Keep it TT.

ok sorry right side then

does any one know?

I already chopped my headers and have them redricted to joined to gether above my transmission

You've been given proper information. You are wasting your time at this point.

The next time you multi post you will be given a suspension.

with the a bunch of diffarent questions if you dont know dont post all your doing is wasting space on my tread
and that last post ok and if you cant answer the question why are you wasting my time ?
you made makes you sound like a little nark

if you cant answer the question why are you wasting my time ?
with the a bunch of diffarent questions if you dont know dont post all your doing is wasting space on my tread let someone who knows what there talking about post.
and that last post makes you sound like a little nark

Kid you are laughable.

First the "narcs" are under me.

You notice how my username is a different color?

Look at the bottom of the forum, I am a moderator. I can make you go away with the few clicks of a mouse if I see fit.

You are posting in MY section. Multiposting is ALWAYS frowned upon and I frown upon it to the point to where people will be disciplined for doing so. I issued a warning to another new member today as well.

Another thing, learn how to use proper punctuation. Reading your posts makes my head hurt. 99% of the other forum members here will ignore you for your poor posting habits. Maybe thats why no one else has responded to your thread.

Wasting your time? You are wasting your time by not doing your own research and depending on other people on a forum to handfeed you all the info you want.

Again, you have been given proper info. You are wasting your time if all you want is a single the same effeciency as the stock turbos.

The saying goes, "Go big or go home"

You were warned about multi posting, enjoy the 24 hour vacation.

i gotta say i'm a bit confused. You're willing to go through the trouble of all the custom fabrication, which it sounds like you already have, but you dont want to be bothered to supporting mods and tune for a larger turbo and more boost? After custom fabbing, that should be the easy part.

Anyways, here's a link to Stealth316's Turbo Upgrade Guide (http://www.stealth316.com/2-turboguide.htm)

There he has listed flow rates and specs on many different turbos, as well as the factory 9bs. Now, keep in mind i dont know Jack Shit about turbo specs and how a twin setup would relate to a single, but just looking it would seem a single 19T is the closest TD-04 match for flow rate.

And to go with ONE 19T would be beyond retarded.

It sounds to me that this kid wants to do a single turbo just so he can say "HAI GUYS I HAZ A S!NGLE TURBO" :rolleyes:

ok thanks I will check that site out.
I do plan on going with a bigger turbo but not at this time.

As for you stealthee IM building this car for show , something you would
no nothing about by the looks of your car!
and I do go big thats why I bought a 08 srt10 viper

You really like pushing your luck don't you?

I could have been a real asshole and suspended you for a week or longer.

With my car I get more compliments on it than I can think of. So if you think you are insulting me, think again.

You were given advice. To bolt on a small single turbo is retarded. If you are doing it for show you are not going to gain any points for having a tiny ass turbo as a single. It will hurt you.

Go with a large turbo and be done with it. If you dont want to or dont know how to tune then dont even bother with doing the single.

I dont have time to rebuild my motor to support the extra boost, I run a salvage yard 6 days a week
I have another block im going to build over the summer in my spare time,
and I have a bounch of used turbos to play with so its just a simple as bolting one on not two.
and your car looks like a failed atempt to what Im doing, making my 3s look like
my dodge viper

You can enjoy 48 hours off this time.

:lol: That's cute...he's making his VR4 look like a Viper. :rolleyes:

PS: I am sure that single 19T turbo will be awsome! :rofl:

Now, if you had ANY clue what you were talking about you'd know you don't have to build the engine for more boost. These engines are very stout. Its all in tune.

You will be wasting your time building a single TD04 set up.

Go with a bigger turbo if you insist on going single, get the proper supporting mods (ie fuel, logging equipment, etc) and your car will be ready. Why do it twice?

You can answer when your suspension is over. Just be warned every time you step over the line the punishment will get worse.

cool I'm aloud back on .

I checked my book and it says that Volvo's use a t19
im building a vr4 motor,I have a sl motor in my car.
I don't want to go bigger with the sl because,It has higher compression

if your going to be running any boost on a 10:1 compression motor, you should get a logger.

any recommendations?
Any advantages switching to a gm maf ?

update!
Does anyone know how to reset the inner butterflys,after the actuater was removed?
Shoud they be open or closed,when bolting on the acuater?

Do you have any pics of your car?
As far as single turbos go, Stealthee is absolutely right. You won't make any power with a small single. There will be FAR too much back pressure there.
You NEED to go with a larger turbo to go single otherwise it simply won't work.
-Steve

PS- technically speaking the right side is the rear, and the left side is the front. hehe

ok I dont know very much about turbos but,
If there's twice the exuaghst pressure to one turbo,
wouldn't the turbo spin
faster? meaning I wouldn't need such a big turbo?

A small A/R (Area/Radius) causes the exhaust flow to enter the turbine wheel more tangentially, which reduces the ultimate flow capacity of the turbine wheel. This will tend to increase exhaust backpressure and reduce the engine's ability to "breathe" effectively at high RPM, adversely affecting peak engine power.

In your case, it is an extreme. Using a tiny A/R fed by all 6 cylinders' exhaust. Not ideal to say the least. Will it spool up faster? yes. But it will choke itself out just as quick.

Do what you want man, It's your car. You have been given the info you need, and you will use it how you see fit. It seems to me though, that you "should" educate yourself on turbos and choosing turbos prior to taking on a project like this.
Good luck

WTF I posted this morning in response to his last post and its gone. Its like the server ate it. :confused:

Oh well, Steve's response covers it.
