If you cant find a manifold do a rear mount turbo by the trunk. It's alot of piping but it will be easier than custom making manifolds.

 

^^There should be plenty of manifolds on the market that would do the job. I know the jbody guys had few options, so at least one of them should work for our cars.

 

Rear mount is more trouble and could lead to more issues than it's worth. Finding a manifold is not a hard task. I could name a couple places off the top of my head.

I would also suggest getting a high temp coating for the manifold to keep engine bay temperatures down and to also prevent cracking of the manifold from long term use/abuse. Jet Hot is a great company and they provide a 2000+ degree coating that they gaurantee won't crack.

Another question to ask you is are you running a internal wastegate setup or external cause this is important when finding a manifold (i'm assuming you're going external cause you said in your original post about getting a wastegate but I wanted to be sure).

Exactly.

 

right now im probably gonna save up for the TAG kit until i hear back from someone about their custom turbo kit their making.

 

does any1 know what the 1/4 mile times are for the cars with Tag turbo?

 

im guessing mid 12's

on low boost and a conservative tune

 

ok here's my idea, this may sound really retarded but it might work too......... what if instead of getting a turbo manifold, you installed the turbo in the downpipe where the cat goes, there's plenty of room and it's further away from the heat of the engine as well........next thing is if it's internally wastegated do you need a bov, and also if you gut the sc can you just continue to use the boost bypass on the sc and end plate instead of a bov?

NJHK?

 

The manifold does much more than you think of just a place to put the turbo. The manifold is there to keep the turbocharger completely still, which will keep the oil lines still and keep a constant oil flow going vertical. It's also relying on the manifold for balance on the engine. If you were to just put a turbocharger (a decent size one is pretty heavy) just hanging around, it would be asking for trouble.

Having it be underneath the car is another thing asking for trouble as well.

The wastegate has nothing to do with the job of the blow off valve. The blow off valves job is to prevent compressor surging (air making the compressor wheel spin in the opposite direction). Whether it's internall or externally wastegated, it's needed. FYI, the job of a wastegate is to "regulate" the speed of the turbine to create a certain amount of compressed air on the compressor side.

The bypass valve on the supercharger, I would disable it (which I believe you can with HP Tuners). It works very differently than a blow off valve. The bypass valve (on a roots supercharger) stays open and then closes when entering boost...a blow off valve stays closed and then opens when releasing throttle.

 

awesome, thanks for the prompt reply, do you think if you went w/out a flex pipe you could keep the turbo steady and level enough, im not actually talking about just hanging it there but that being the location in the exhaust setup. the location of the cat is still protected pretty well its a few inches above the undercarriage..........or do you think it's just a bad way to set it up?

 

You're welcome

But honestly, the farther the turbocharger is away from the engine...

1. The more distance there will be for the charge pipe - there could actually be a slight pressure drop. The more bends and travel air has to travel, the less pressure there could be.
2. The longer distance oil has to travel into the center section
3. The longer distance exhaust has to travel to enter the exhaust housing of a turbocharger. It's much more beneficial to catch the initial exhaust momentum coming out of the exhaust port during the exhaust stroke (when the exhaust valves). This might be minimal...but the keyword is might, you sometimes have to think in theory to come up with the best setup.

And also, having it even being lower, you have to think about gravity pushing oil downwards back into the oil pan. If it is parallel with the block, it will be more likely of it backing up into the center section and that would just cause a world of problems right there.

It would not be steady. To do all this just to avoid having a manifold is just silly in my eyes.

 

awesome those are the exact answers i needed, i was hoping to keep my pacesetter header, i love it, but it won't be practical with a turbo, my next question is does the 2.0 produce enough exhaust to spool up a gt35r w/out massive amounts of lag? or do you think a gt28r like the tag kit would be better till i get the heads done, i want to go big boost with minimal lag, if thaats even possible on such a small displacement engine.

 

Yes, very possible to.

People over exaggerate "lag" like you slam your foot on the gas and the car doesn't move and then BOOM boost and you're a rocket in space. Even if there was any amount of delay in response that you notice, there are many of ways to improve this...

i've never ran a turbo before, so i don't really know what lag is like, the way i figure it a little bit will be good in first gear so i can launch a little better, just as long as it doesn't affect me on a road course.

 

Lag is usually over reacted. You should be fine.
