Please tell me about your Vishnu STage 3 Turbo kit with the 3037s turbo? How is at as far as a street turbo? What sized injectors should I use? Power on pump gas?


Dyno's mean poop as I use a Dyno jet and you use the Mustang, But I am looking for 123MPH Traps on 93 pump and so on....

Also my 2nd biggest concern is the manifold and cracking, is there a support bracket with your kit? Will the Downpipe fit my Buschur Racing Exhaust? Streetable?

How does this turbo Compair to the T3076R?

Thanks

 

better turbo than the 3076, 123 on pump gas is pretty freakin fast. I don't think you can run that on pump gas on ANY turbo set up with this car. None of the 30 series turbos REALLY shine without race fuel. They perform, but 123 is asking a lot.

880 injectors would give you plenty of safety margin. Not sure about the support bracket on the manifold, and i think the buschur cat-back uses a slip fit, won't work with a normal downpipe/testpipe IIRC

 

I have personally Seen a 122MHO on an AMS GT3076R on pump. I was wondering why you say that a 3037 (Vishnu one) is better then a GT3076R???? Better topend? Better spool? Just no idea really.

I am looking to make around 430WHP according to a DynoJet on pump gas, 500WHP on C116 would be nice as well. I also looked at their website and see that they have one manifold design and yet I have seen another version of it shown here.




I am wondering if there are different versions of the Vishnu manifold and which is better? This one appears to allow the use of a STOCK Heat shield.

 

Also does that Manifold have an EGT port? Looks like it

 

That's the older version of their manifold. I would assume that the newer one performs better...why else would they change it?

 

IDK, also raises questions on why they changed it such as (MAKING THeSE UP!!) Cracking, not making the WHP desired, no support bracket, etc.


Any solid info such as Dyno's or WHP.

The reason why I ask is becuase I am in the market for a turbo kit and ALL I have been looking at is the AMS/RNR/ATP stuff, I have no idea on the Vishnu stuff's.


Thanks.

We kind of covered that in this other thread, but I'll lay it out for you again.

The only difference between the Stage 2 and the Stage 3 is the manifold and for pump gas there is no difference in spool or whp. You seem to be leaning toward only running the pump, so stick with the cast if you are worried about cracking.

The tubular manifolds make more noise and ALL of them have a propensity towards cracking. Even the cast manifolds glow orange like lava under full boost so after a while a tubular can crack, although Vishnu, AMS, and Buscher will warrantee them against cracking (iirc), but they are not as strong as a cast manifold.

The Vishnu comes with a support bracket for both stage 2 and 3. Vishnu's stage 3 tubular manifold has an adapter for a stock heat sheild, Eric at AMS can make a heat shield/adapter for about $300 extra (I think that's around what he quoted me) and the heatshield will be located higher than the stock position.

3071 turbos spool a couple of hundred RPM sooner, 3076 is very close to a 3037; Eric at AMS claims the spool is slightly better than the 3037, Shiv says he see's a little more hp on the 3037. The 3037 and 3076 are pretty much a personal preference and split hairs. I am told the 30R is the same as 3037.

If you run pump, run the 3071, it makes about the same as the 3037/3076 with quicker spool. Might as well run a cast manifold as it makes the same hp on all 3.

If you want to change to race gas, the 3076/3037 are great choices and will give you about the same hp (within 15-20 whp) with a cast or a tubular manifold. A 35R will probably benefit from a tubular manifold.

 

Goody, So now I gotta get the Buschur kit, only $3000 for a full kit

 

Not really, doesn't come with downpipe or injectors, the vishnu kit does. I believe the vish kit comes with lower IC piping as well, and the buschur kit doesn't, unless you have one of their intercooler kits. But im not 100% certain that last part.

It is a tough choice indeed on who's kit to go with.....but i think the 3037 is a better turbo than the 3076, after doing a good bit of research, the 3076 at 35r type lag with 3037s type power.

 

It is possible to run 123mph on pump gas if:

1) your pump gas is 93-94 octane (not the ca91 junk we get here)
2) your running a GT35R

Our shop car ran those traps on 93oct before. But it didn't really come ALIVE until it was running 100+octane

Shiv

 

I have 93-94. I want 120+++ Traps on pump, my goal.

 

This statement is wrong. The 3037 is an HKS number. First off, their are 5 different versions of the HKS 3037. The most popular one, HKS 3037S, is exactly the same as a GT3076 (in regards to CHRA). Both have 56 trim compressor wheels and 84 trim turbine wheels. The only thing that differs Between a true 3037 and a 3076 is the T25 turbine housing developed by HKS. Which nobody except HKS uses for there own turbo kits. I hope this clears this up.

 

What does a 3071 have???

 

you telling me the Garrett 3037 and 3076 are the EXACT same turbo?

 

And people wonder why I have no idea what I am talking about
