Hello
are there any people out there who think/try a Turbo mod on an NA V6?
Bolt on with the original compression rate?
I hope my english understandable

Not that I am aware of. Although people have swapped 6A13TT engines for 6A13 in the past, search for vr2.
There is one V6 SOHC in NL that has been modified with an Eaton compressor. He did change pistons and other engineparts. Power output is/was around 280hp! I've driven it and it's quite something else compared to a Turbo-ed V6 (VR2) or a true twinturbo VR4 AWD. It felt very very fast and the sound of the compressor was awesome!
Yea i know Vr2
But in my head there is the idea of a single turbo 6A13.. just in theory..
btw the 6A13TT pistons would fit to lower the compression?
The block is the same so why not? not going to 280hp but maybe 220.. i know that the DOHC would be better but for lower power the SOHC can do that or im wrong?
EDIT
I dont want a compressor cuz more ppl working/ modding/ tuning with turbos i think there is more know how
but i know the V6 compressor
BTW what would happen if i only mount a turbocharger to one cyl. bank?
there are people who have done single turbo conversions to a 6A13 engine, but all were 6A13TT before.
If you mount a turbo to one cyl bank only you will not have enough spool to have constant pressure. That is senseless.
Further the block itself may be the same between SOHC and DOHC Turbo but oilpan design etc. may be different. Easiest way is, to swap a 6A13tt in. Relatively easy job as much is plug & play. Been there, done that...
the one and only...Pearl White Legnum 25 ST-R...registered in Germany - now featuring a 6A13TT engine (unless you know otherwise)
The oilpan from TT has the connections for turbo oil lines or?
The exhaust manifolds from DOHC would not fit i think..
My car is a 2000, so with 120kw not 118kw..
That would be the easyest way i think only rework the exhaust manifold to connect the 2 turbos..
I know that a swap is not as hard but i like the idea of power up the SOHC.. if the engine would blow up than we all know its crab
In theory i need
2 Turbos
Manifolds who fit
All oil& watercool line
Modified Motor management
Air intake pipe
Wideband lambda
what did i forget ?
Sry i hope u all dont hate me now cuz i wanna talk bout some ideas
Can i run on normal NA compression with lower boost?
What is normal boost? 0,6bar?
NA= 9,0:1
TT=8,5:1
am i right?

This is something I've been thinking about too. I have both an NA block and a TT block, and I'm in the process of porting and rebuilding a set of TT heads with the uprated springs and reground cams that @Adam.Findley organized. I've been wondering if there's any point using the NA block instead of the TT block, and making a really good tune to make use of the higher compression.
You'll want to lower the compression ratio. I looked into overcharging a na v6 mondeo a few years ago and was told by pretty much every supplier of compressors and tuners not to go above a couple of psi with the standard compression or your just gonna desperate the heads from the block.
I know when this has been done before on straight 4's they used to use like a 5mm thick copper head gasket rather than changing pistons rods and cranks.

SO FAR....
Are there any thicker gaskeds for the V6 or replace the pistons?
Off the shelf? I have no idea
There's always custom made, the only limit with this sort of thing is the depths of your pockets.
The real question is do you want to risk a lot of money on something that may or may not work, or if it does not be useable as a daily driver due to the way it makes its power, reliability etc.. Especially when there are easier more well trodden paths?

Sorry if my earlier post sounded negative.
If I was to contemplate this I would think about maybe a single turbo running off both banks and have it low pressure. Two reasons for this.
1. Simplifies the pipe work, pre turbo intake and post intake, the exhaust side would easier as well.
2. Rather than trying to increase power with boost I would be thinking about trying to increase the volumetric efficiency of the engine. Much like what they did with the early turbo diesels, using the turbo to clear out more of the exhaust gasses from each cylinder as opposed to trying to cram extra air in.
If I was going route 2 I would probably be thinking more about a small belt driven supercharger. But these can be stupidly expensive. But the balance between an expensive blower and cheaper pipe work compared to cheap blower and potentially very expensive manifolds if you pay someone to make them up. Might cancel each other out.
Edit: here's a link to the sort of blower I'm talking about. This company were very helpful when I thought about doing my mondeo.

the 0.5:1 comp ratio difference will make next to no difference at all, as long as you don't don't go daft on the boost.
there have been lots of different manufacturers that have done low pressure turbos on high cr engines with some good results. I think the v6 will be a good one, in fact i'm so convinced Myself and danzul are already starting one for his v6
Thanks for your tipps and ideas
So i should get the two exhaust manifolds and a good welder
I think that would be a nice project.. what turbo would u use?
And i dont want a sc cuz i dont wanna have even more belts^^
Manifolds yes welder yes! Unless you can weld yourself? Would help keep costs down and its always a useful skill to have!
As for turbos, do you want 2 smaller ones like a vr4 or one larger one?
2 smaller = less lag but more pipework (exhaust, inlet outlet, oil, water)
1 larger = more lag, nut less pipework ( would have to be run From both banks tho)
Agree with sc decision, I think this is why so many people don't use them, pluss mounting in tight engine bays can be a nightmare.

So definitifly no sc!!
No im only able to weld easy things.. i know the basics and i have no own welder..
I would prefere a single turbo cuz its more easy than two..
And even a single turbo with lower boost would give a kick or?
What type of turbo would u take? Manufactur?
Even a single would make a difference, I'm not really up to speed on which turbo's if I'm honest, not done the research before but you would need one that can flow enough for a certain boost pressure, the td-03's on the vr4 tend to run out of puff around 1.3bar ish I'm led to believe so I gues one of them could flow enough for 0.5bar, this is only guess work tho. I'm sure someone else with more knowledge will chip in soon tho.

So one would be enough for a "light" SOHC turbo mod?
And how big should be the Intercooler? And i prefere a FMIC or?
