Turbo BB?

[Moparmatt72]

The turbo off the diesel you can use it. And the 4" can be for the down pipe all the way back if you want. These are the type if they are the same your talking about. True you might not need a intercooler but keep in mind it will be better for the turbo and it helps makes everything run better, its something to keep in mind can always upgrade to it later.

There is room for 4" down pipe with the small block, but barely, it starts out 5" and necks down. we used stock truck manifolds.

If you stay below 6psi, then you'll be ok, after 6 you'll need inter, meth injection or run alky. The inter is also another issue, not any size works.
This is why you might want to explore the turbo in the exhaust, then that makes the pipe out less of a problem.

This may be a very stupid question, but forgive me, I am new to turbo's. Do both the exhaust manifolds need to be routed into the exhaust inlet on the turbo? Or can I still one run one side normally with the longtube and the other with the manifold/exhaust inlet? I may run with an inter cooler, it is not very expensive to run one in comparison to everything else. I was just told by a friend who has an 800rwhp 347 foxbody mustang and a brother with a 700rwhp procharged mustang, that it probably wouldn't be necessary at my boost level; but I will probably do one anyways. It seems like the diesel turbo's are much more trouble than their worth, they don't have typical flanges and most have an internal wastegate. Other than that, they look plain monstrous.

 

[Moparmatt72]

You will need to run both sides to the turbo will help spool it up better and faster then running off one side only. I believe the diesels are a 72mm I can always meassure my dads 06 and let you know unless some chimes in on that. If you want check out cxracing they have universal kits and they work great had one on my srt4 neon and was pushing 25+ psi and had no problems. If you get one that is minimum of 3.5" thick it will be fine a 4" core won't hurt either as long as its a good intercooler and has minimal boost drop some are up to 3 psi drop where the cxracing was 1 psi drop across the intercooler.

Ok, I just learned I cannot run an exhaust manifold upside down by FEETS on the other Mopar forum. Back to the drawing board. Maybe a rear mount is the way to go in this case, will a rear mounted oil system w/ cooler. I have plenty of room under the fuel cell. Feets stated a T76 would be a minimum for a rear mount 440. Piping would actually be easier, Muffler shop would need to run a pipe from the rear of the car to the front for the intake portion. Couldn't see it costing more than $500. Okay, I am thinking of oiling. Rear mount oil reservoir (maybe a stainless aftermarket power steering fluid reservoir would work, 2Q capacity?) have the oil exit the turbo with gravity, into the reservoir, the reservoir hooks up to a Mocal oil pump and into a cooler, then back into the oil inlet on turbo? Am I on the right track here? Would probably use this type of hose; http://www.summitracing.com/parts/sum-230610/overview/

Ok for the exhaust mount (under the car) i would merge the exhaust up front and run it back to the turbo, situate the turbo how you like to make it easier to deal with.
I would use AL charge pipe back to the front so it also acts as cooler.
Oil you could do 2 things, plumb a line to the turbo with a scavenge pump to bring it back to the oil pan, or use a cell or other tank (like a peterson dry sump uses) and use elec pumps to circulate the oil, now the 2nd option for oiling leaves out the engine and leaves the ability to run the oil longer for the self lube system for the turbo

Mocal might work, but you may want to see rbracing-rsr.com

This is a picture of the beginning fab work. There is a Y right below the turbo. There is no need for an inter-cooler with a carb and E-85 for fuel. That's the ticket. Detonation is a non issue @20 psi.

Well, I really don't want to go the custom header route. That will tack on a grand to the total with ease. I have a very large amount of room for a rear mount. I was thinking to merge them together with a 'Y' (I am running 3" tubing as it is) to the exhaust inlet on the turbo. The exhaust outlet would be a simple 90* 5" dump. Breather would be very simplistic, just would be difficult to run in the rain, I would need to place a shield in front. The Mocal pump has good reviews on the Turbo forums, and is fairly cheap. I am just trying to budget this as much as possible and get everything worked out.

Twins are a whole lot easier to package. Each one can be smaller, you can go down out of the manifolds, forward, then turn up into each turbo. Add a wastegate to the elbow where it turns up into the turbo, have the turbos face forward and run the downpipes over your manifolds and down since they'll be smaller or turn the turbos to face each other and kick the down pipes out through each of the inner fenders. Adding another ebay turbo isn't a big deal or a huge expense.

 

[Moparmatt72]

Could just run two turbos plus if you go with inter waste gate turbos cuts cost down a bit and if you ran say twin 50mm turbos and kept boost the same make about that 650hp or a bit more.

 

[Ryguytoodry]

If you're only looking to run 10 psi, find 2 gt28's or td04's and run each off of your exhaust manifolds. Use an intercooler, pick one up off of a old turbo volvo from the junk yard. Best flowing stock intercooler. Make sure the tune is right though. I suggest getting a wideband 02. Boost likes lower lift cams with high lobe sep., longer the gears the better, and stick it in front of an auto. Don't forget that it seems cheap as first, but it ends up making you broke by the end of it.

I planned on doing boost for my slant, but now I'm going all motor with a little shot of nitrous. I cant justify the cost of it, plus that fact that the tune is so critical all the time and all the extra parts/stress raise the statistics of something breaking immensely.

Only issue is, it isn't just another added turbo. I am into it for another waste gate which is $200 used, and another BOV which is another $225. It just adds double the possible failure rate as well. I just want to keep it simplistic as possible for tuning and overall sanity purposes. A 2x3"/1x3" Y-coupler, merged into a single 3" pipe to go over the axle and into the exhaust inlet. 4-5" down pipe dumped toward the rear.

Anyone have anything to say about the 'on3performance' turbo's? Looking at their 76mm unit, probably would switch to an 1.15ar exhaust housing. Would this turbo work well? It's only $319.

[Moparmatt72]

If you haven't bought the turbo yet look at intergated turbos then you won't have to add the cost of getting waste gates on top of the turbos they are built in.

Look like this the intergated type

My son runs a nearly stock 360 in a 62 Plymouth. At 20psi it's been 10.08@136 with 275/60 drag radials and 3.23 gear @3700 lbs. Even at mild boost (12psi) it ran 10.60 with a 2.76 gear. Blow thru,E-85,stock manifolds,rods,crank.

Dang, that is a sweet looking ride. I love it!

 

[Ryguytoodry]

It's not an added bov... Run two small ones into a y pipe and and put the bov where they merge. Also, I would only ever run a known brand name turbo.

This is what happens when you cheap out:

 

[Supershafts]

A single is much easier to do than twins, even if they are smaller.

And smaller can also have turbos always in boost.

 

[Sweet5ltr]

On3performance turbo kits are sold by Jegs. I wouldn't say they are that remote in terms of popularity? I mean, the car may now see only a few thousand miles every two or three years anymore. I will only be running 8-10psi, this is nothing outrageous in comparison to most that is not why I am worried about an outrageous turbo. I think two small twins would just be twice as much potential headache.

Ouch! That musta hurt.

You guys are way to complicated. 1 turbo, 1 carb, no intercooler. At that low boost just run off the BOV spring. Get some low performance truck manifolds, turn them around backwards (left to right swap). Plumb it up blow through E-85. Minimal timing. spend money on a good e-85 blow thru carb and get a good fuel pump. Run 20-23 total timing at 10 psi and have fun.
