Damn, I'm gone and it goes to 3 pages...

I would like to say that a remote mount setup is just a big waste of time and there are many negatives that can come out of it.

Remote mount setups were made for vehicles (example: big v8s) with tight engine space that could literally NOT fit a manifold design in the engine bay but still wanted to utilize a turbocharger. The negatives are:

1. Longer exhaust travel to hit the turbine
2. More charge piping which will take longer for compressed air to reach your throttle body which can also result in a loss of pressure.
3. Having the turbocharger being so low to the ground leaving MORE room for it to get phsyically damaged
4. Longer oil lines (which may also require an oil pump to keep up pressure)
5. Possibility of the oil lines getting kinked or damaged

I can go on but I think that's enough.

The point is that there are more possibilities of negatives and it's unnecessary to do such a setup if you're more than capable of keeping it inside the engine bay where these negative possibilities are lower.

You actually couldn't consume all of the CFM it can make because of restraints caused by our engine's displacement and the limitation of RPMs of the supercharger. Only a larger or more "hungry" engine/air pump could make this much power using this blower.

I'm not saying you couldn't make quite a bit more by adding flow to the top end, but as Witt said, even GM's full race head will not flow this much CFM.

Edit: This is why 2.2L with our M62 setup makes more power than we do with the same pulley, rpm, etc. etc.

Like I said before, go with a newer designed GT series turbocharger.

A GT30 would be excellent.

Also to anyone questioning the response, there are many of ways to improve response without even touching the engine but these turbochargers, honestly, you step on the gas, you go. Some people over react the delay of a turbocharger (if there is any). If properly sized, you should absolutely fine and even if you did have a very slight delay, people care about power in racing, you stay in your higher RPMs and you'll remain full boost pressure realistically.

A gt30 is about the biggest I can think of without requiring a two step for launches for any decent track times. just imho.

Well actually,

The gain in power (in my eyes) have more to do with the displacement AND the raise in compression. The heads flow similarly. They also still only rev till 6500.

Im confused as to "only rev till 6500" the 1k and 1400hp builds are wound out to 9500 rpm

Yeah that's what I was saying. The amount of CFM utilized by the engine has to do with the displacement. Although our current displacement is also limited by the flow of the head. Therefore even if you maximized the flow of the head, with stock displacement and compression ratio we would not use the max amount of CFM produced by the M62 at a suitable RPM.

My bad NJHK, I thought you were speaking in general . Now I know you were talking about the 2.2L.

OK, I don't know anything about turbos so I'm taking all of your advice, thanks for helping me out. next thing, where's the cheapest place to get a GT30 series turbo?

They claim a 3800rpm spool on a 2.0 liter engine. GT30s are a ball bearing unit, so they're not going to be cheap.

Huh?

We are talking about the M62 on a 2.2L (L61), not the GM race engines.

I think that's going to be a little out of my price limit right now. What's the problem with the T3/T4? It's way cheaper and I heard it spools really quick and is good for 450hp

T3/T4s are okay. If you want to use one, go for it man. The GTs are really nice though; it is what I would buy if I had the money right now.

Somebody mentioned something about an sts setup. May not be too bad of an idea, but it wouldn't be my first choice for this application. Consider this-

STS claims lag on their systems is no worse than a conventional turbo setup, and in general, this is fairly true. The reason being, they use considerably smaller turbos than a conventional setup will. The turbos they use will not be efficient at the levels of boost you are looking for if you are aiming for high hp numbers out of a 4 cylinder...20+psi is going to be tough on a remote mount setup without major lag. BUT this may be something fun to consider. You could quite possibly create a y-pipe setup, for a twin turbo system if you went remote mount. It would be very possible, could potentially spool quicker than a conventional single kit (using tiny ass turbos) and make the same kinda power levels. If you plan on running really high power numbers in the future, this could also be beneficical because you don't need nearly as large of an intercooler with a remote mount setup because there are huge temperature drops in the cold side piping alone. Those things can sound REALLY cool too haha. If you were to do this, you could also do the install yourself MUCH more easily than you could with a conventional setup. I would never do a remote mount setup on a daily driver though you guys. For a few reasons.

A. you get in a fender bender you could lose your turbo and lots of piping.
B. go over a speed bump and you could scrape the **** out of your turbo/piping.
C. I still don't fully trust the oil delievery on those things. The oil has to travel way too far for a gravity feed, so you need a pump and if that pump fails, buh-bye turbo.
D. I will personally be stealing your turbo from right behind your bumper while you are at work.

Turbo is for sure the way to go though, don't listen to anyone that tells you to stay with the m62 if you have high power goals...you will just end up spending more money and having more headaches.

haha. Do you know what an m62 is? do you know what 500hp is? I hope to see those two things in one place sometime in my life, but i expect it about as much as i expect carmen electra to start blowing my dick within the next 30 seconds. You have no idea what you are talking about if you think you are better off keeping the m62 if you want high power numbers. Costs to make a 500hp lsj with the m62 >>>>>>>>>>>>....>>>>>>>>>!!!!! costs to make a 500hp lsj with a snail.

Conclusion:
You have no idea what you are talking about.

yes back to topic.

advantages-

gt30 although bigger is a ball bearing turbo, so spool time will be comparable. The gt30 is more efficient. The gt30 overall is really a better turbo, but there are TONS of different variations of the t3/t4, so that could end differently. What exactly are your goals here? How often do you plan on driving it on the street? What would you like to be able to put down in the end?

I go to the track every other weekend. I drive the car for fun, I want it to be streetable. Looking to do 320-330whp right now and 420-450 in the future.

Conclusion:

An m62 is a positive displacment blower it displaces about 1l p/r peak output at 13.5k rpm of 825m3/h and only designed for about 10psi of boost

I do know what im talking about
With the cnc ported head you should be able to achive about 450-500 hp with a ported blower and proper supporting mods. The m62 has the cfm to make that much hp. Not only that if you upgrade your heat exchanger to a much larger unit like a fluidyn 3 row what little heat the blower will produce will get absorbed by those fancy little laminova cores that those crafty sweeds of OPCON group created.
Now if you dont belive me that is your problem but i am not lying

One advantange of the T3/T4 setup over the GT30 is that the T3/T4 turbos have been around for a while and parts are cheap and easy to find as where the GT series is a newer turbo and parts are more expensive. Just my 2 cents.
