6.2 Banks Turbo wanted!

[thomas.bill]

Hi!
I am a Swedish Chevy-owner and I look for a a better used Banks Turbo kit with the most imported parts to my Winnebago -84 with a 6.2 diesel. I have an adress to a company in USA who deliver to Sweden.
So, I need more power in my Winnebago and I hope I can find it here :)

Don't know what chassis you have.

Take a picture and post it up.

The Banks turbo kit only fits Trucks, Suburbans and Blazers. There was not a kit available for a P Series chassis. There was one made back in the day for the G Van series, but is not available at this point in time, and were rare even when produced.

At first, thanks for the answer!
Second, it's a P40/P42 chassie 33'. What I'm looking for is the part son the engine then I understand I had to make my own exhaustsystem.

Or.....do you mean that the Banks system don't fits in anyway?

I look forward for an answer. :)

There's a thread from a few months ago with some good info and pictures of the two Banks kits:

http://www.thedieselpageforums.com/tdpforum/showthread.php?t=42455

Scroll down a bit and there's a picture of the early kit (Bank 21002) mounted to an engine on a stand. That should give you some idea of how that kit would/could fit in your engine bay.

The newer model version (Banks 21007) moves the turbo back a small amount. The manifold in that kit places the turbo near piston #4. Then the crossover pipe is totally different, routes around the back of the engine. As Jim pointed out, this whole setup is similar to how GM handled the turbo mounting and crossover routing on the GMT400 trucks. If this setup works better for you, you might consider just getting a used setup off a GM 6.5T truck. But if memory serves, a GM 6.5 turbo setup on 6.2 heads can have interference because injectors got angled differently? (I'm sure someone will chime in about this swap and there's tons of threads dedicated to it.)

[thomas.bill]

Hmmmmm. The manifold from a 6.5 can I get here in Sweden, the crossover I hope I can buy as a part by Banks (mabye expensive).
But as you wrote, does it fit? I think I mabye had read somewere the AC holder don't can be used.

Before I'm going to the vinterplace for my Winnebago, please can someone give me an anser. :confused:

Ps. Sorry of mine and the IPad bad English (it's setup for Sweden) Ds.

[TrenchFoot]

I don't think that parts interchange between the GM and Banks setup (manifold from GM, crossover from Banks). I was trying to point out that the later Banks kit (21007) is very similar to the GM 6.5T setup.

But I'm no expert. I don't even have a running 6.2 yet and my Banks kit is still in the box. I've just been reading/researching this setup for ~3 years.

First I'd figure out what setup fits your engine bay best:


old Banks 21001 (turbo forward, crossover up front)
new Banks 21007 (turbo set back, crossover around back/under)
GM 6.5T (similar to Banks 21007, may need head swap for 6.2?)

You may not have clearance for the turbo/downpipe/crossover for any of these setups in a P-series and need to find a turbo setup that mounts upper/rear like was used in the G-series vans.


Anyone with real world experience wanna chime in here?

[thomas.bill]

Hello again.
I find a picture at the net who show howe it looks under the hood (from an oversize view). What I remember it's "plenty" of place between the manifolds and the frame plus the exhaust is under the floor.

I hope this will help the experts a little.

Can't be of much assistance there.

There were not many 6.2's in motor homes.

My advice here will be to do a google image search for Banks 6.2 Diesel and look at the setup relation to what you have installed in your chassis and see whether the turbo manifold with turbocharger looks like it will clear the flooring etc.

Buy a used setup online with most of the pieces and fab the rest if necessary, that way you're not out the full cost of a new kit for something that might not fit.

go straight to banks and ask them. just my 2cents. highdesertranger

[thomas.bill]

A mail is sent to Banks, I hope an answer will come...:cool:
If not I had to do like Master Yoda = by myself (link below). There is "plenty" :rolleyes: of place to mount one or maybe two turbos serial if I borrow a little place inside the RV under the sofa behind the driving-place.
Perhaps I can shift right and left manifold and mount two turbos near the wheelhouse, we will see....

I take a turbo-brake for now, the RV has it wintersleep right now so I had to wait to the spring (here in Sweden).

If anyone have any tips or ideas you´re welcome.:)

My next search is a GearVendor to my TH400 with manual parkingbrake on the driveline, do YOU have one? :confused:

Once again, thank´s for all help! ;)

I have a 6.2 in 1986 chevy blazer. I did not want to make the jump to a turbo. Mainly because I wanted to have a hot rod NON turbo diesel (if that's possible) My truck has an open plenum intake, opened up fabed ram-air system, headers w/ open exhaust and the Injector pump tuned up. Many other little tune-ups in the engine bay. Performance increase was VERY noticeable. Hard to say what it really was, some day I will put it on a dyno. So there are other options for you to get more snort out of the engine. One thing I would recommend is head gaskets if you already haven't done it.
The GearVendor is GREAT product! Fairly bullet proof and simple to install. I have been running mine for about 250,000 miles in two different trucks. it has been refurbed at the factory once. Not because it needed it, but more because I had it out of the truck. The only advice for the GV is do not expect it to really pay for itself anytime soon. If you follow the maintenance schedule it really puts a bite on some of the savings. The main reason I have one is so that my truck can travel with the flow of traffic and not be running 2300 RPM! So potential savings also come from driven accessory life span. And then there is the cool factor....:D
Hope this helps....

Good evening Dvldog8793
I have two good reasons to put a turbo on my RV:
1. I have a Ford PU with 7.3 turbo diesel, that's power :)
2. It's an easy way to get strengh to the RV (if it fits)
But can I have the power in other ways = so what? So far I don't had take a closer look of alternatives.

The Gearvendor, yes I know... It should take maaaaany years to payback but it should make the travelling much more comfortable ;)

As I wrote, tips and trix are welcome

Thomas in a winterland...

[thomas.bill]

I wrote earlier that I should contact Banks about to put a turbo at my RV, I've had a good mail conversation with them about wich alternativ and important things to remember if I build my own turbo (no, they have no kit to my RV).

Last weekend I did 2 good things:
1. Get the RV home from the winterplace
2. I found a very good webside who show an installation of a Banks turbo earlie model, now I'm 99% sure it fits under the passenger floor.

At last, this weekend I had the highest bid on eBay on a used Banks set. It arrive of a couple of weeks, I'm waiting......

The RV-projekt is slowly moving on and I really hope I don't get sad further on.

[thomas.bill]

The container with all my bought things (including the turbo) arrived to Gothenburg last week with cam-chain, radiator and more "good things" to the engine.
Last month I get offered an brand new marin injection pump with barley used injectors.
My question: There is not a lot of place "under the hood" of a Winnebago (look at earlier photos). Can I remove only the fan without to remove the "v-belt holder wheel" (I hope you understand what I means)?
If not I had to wait to change the pump until I change both radiator, pump and cam-chain.
I'm looking forward to your answers.

Please ignore my crazy question above, I thought I had to remove more then the oil tube to change my injection pump to a brand new marine injection pump :D. Today (or tomorrow) I`ll get the injectors back from testing/maybe fixed.
Now I wait for the first step to a better engine in my "little rolling house".

Be really interested to know more about your engine mods - sounds great. Also much along the lines I would like to go with a 6.2 in a G20.

any details much appreciated.
