Yea get it remapped it would work out to be more cost effective than buying one from the states, and i thought Vf chips were never that good in the first place... :?

Mmmmm thats a very nice piece of kit, maybe when the pound is stronger.

 

BUT if you want a stainless manifold then look at these as a cheaper option http://cgi.ebay.co.uk/turbo-Racing-mani ... 3ef7f8e511 and as a best offer the guy WILL take £500 for one.

[Kevin Bacon 5]

That looks superb dude, great find! :D I really like the 2 banks of 3. Would work extremely well with a divided turbo (aka twin scroll) but you'd need a wastegate for each scroll to get the best performance, so could be a pipework nightmare!!

 

Seeing that has made me want to start over, LOL! :D

Hi all,

 

Just to let everyone know I'm a complete virgin to turbo's so apologise in advance for any silly questions or statements!

 

First thing for me to work out, is it even worth turboing my engine? Really you should use as low mileage as possible I guess. Mine reads 127k. Or is it not so bad to use a higher mileage on a VR engine? Just been rolling road tested at 180bhp, pretty standard, exhaust & BMC.

 

I need to do lots of research as this is such a specialist subject. Is there any sort of idiots guide on the components and pricing I would be looking at? I've seen on ebay there is a kit from Canada that says its complete including turbo. The price is £749 or best offer, the best offer taken is £550. This seems too cheap for everything or the quality isn't up to much? Supposing that was ok, any thoughts on an install price from start to finish?

 

Sorry again for lots of questions, regards Matt

127K is fine. Many people turbo high mileage VR6s with no problems :D

 

Stealth Racing aren't far off finishing their Stage 1 bolt-on kit and if you're a novice or new to all this, imo, that's a great place to start.

 

The kit has been developed on their own Corrado VR6, so will fit properly and work properly due to Vince's extensive VR6 T mapping experience. They found and made a front mount intercooler fit with practically no chopping of the frontal area, downpipe is done etc so they'll be working on the mapping fairly soon.

 

If they'd done this a few years ago, I probably would have gone that way myself tbh!

Nice to see a bolt on kit in the UK at last. Like the sound of the intercooler :)

 

What manifolds they using kev

[Kevin Bacon 5]

Stock intake manifold and SPA Turbo exhaust manifold mate. It's the best manifold to use to get the turbo low enough in RHD applications. Vince said the genuine SPA manifolds are nothing like the schitt copies and I believe him as he's seen the schitty ones I had with his own eyes!

 

He wants to minimise the install complexity and overall cost, so stage 1 will be basic. Higher stages can be specced to what ever you want really, within reason!

Nice one , have you seen the intercooler.

[Kevin Bacon 5]

I haven't yet. I'll be going up there in the near future and hopefully he'll have it running and I'll test drive it :D

Eeeeenteresting. You got a ballpark figure of how much this would be Kev?

I haven't yet. I'll be going up there in the near future and hopefully he'll have it running and I'll test drive it :D

 

I've seen it He showed me it when I was there on the rollers, I was impressed as it's quite a big intercooler!!

Thats great, thanks for the quick assist. Be good to see a few details of it when they release them. Plus a rough price from them would be cool. Have to get saving then guys :norty:

[Kevin Bacon 5]

I have no idea on pricing at this stage but it will be competetive I'm sure :D

 

Also bear in mind no one else currently offers a complete kit for UK cars. Sure you can get the bits individually yourself, but as a fully constructed, tested and mapped kit ready to bolt on, Stealth will be the first.

 

And it's about time really. America and Europe have had Turbo kits for VR6s for over a decade :lol:

Hi everyone

 

We hope to have our stage 1 turbo kit ready for the 29th (Rolling Road Day).

We still have a bit of work to do but we will do our best. :)

[carpoid 0]

Sounds interesting, i'll look forward to seeing what parts you're using to make up the kit, any clues?? Short Runner? Custom Exhaust Manifold? What size Turbo etc??

Good stuff Vince

 

Congrats on being the first company on offering a RHD VR6 Turbo kit

 

Best of luck with it

Read back a few posts :D . Stock inlet manifold and SPA Turbo exhaust manifold. Turbo will be a T4 based one, not sure what size at this stage but it'll be enough for 400hp easily :D

[mic_VR 3]

I wonder how much the kit will be, assume it'll be an option to have it fitted as well. Could see a few more VRT's about.

 

Might scrap my 24vT plans and go with this! :lol:

[Guest]

damn this could change my mind on which way to go if stealth are guna do a turbo kit

looking forward to seeing what bhp the stage 1 kit is

 

i am some what a new comer to the vw family, and this may have been asked more than once, but what sort of power can the rado take being front wheeled drive before the power becomes pointless?

i know theres all these new slip diffs and with out a doubt also depends how good a driver you are (meaning if your guna sit there with your foot flat to the floor with the wheels spinnig like a good un then thats your choice haha)

 

but if 400 bhp is more than enuff, would it not just make more sence to get a rotrex charger, i know the power delivery is different to a turbo and turbos can give you a 1000bhp but if there both around the same sort of power would a turbo have any gains, which route would be less of a strain on the engine when driving normaly etc

this is a question as im still deciding which route i wana go in the near future well end of next year haha, and i know some people will be all turbos and others chargers, but if you could be impartial

 

thanks perksy

[mic_VR 3]

You're definitely not the first to consider all the options but I think it comes down to 2 things:

 

1) How do you want your car to behave?

2) How far do you want to go in terms of modifying further?

 

Firstly, A supercharger will give you a much more linear power delivery, possibly considered more composed and less all or nothing like a turbo setup. Although a turbo setup can be mapped to make them far smoother and deliver the power much more consistantly, but this can be very time/money consuming. A turbo will give you that kick as you're buried into the seat which lets face it is what most of us are after! :norty:

 

Secondly, A turbo gives you a lot more scope to up boost in the future without having to take everything off again and swap parts over. Usually just a remap and a little bit of tweaking on setup. I'm sure people on here who've tried both will say that eventually they've gone turbo after a supercharger setup.

 

The other thing I personally think is that a turbo is a lot more efficient, it works off waste eshaust gases and doesn't produce a load on the engine. The upside to this is that people quite often get mpg figures (off boost) that are almost as good as a standard engine.

A supercharger has a parasitic load on the engine as it is driven off the auxilliary belts and therefore expect a fair drop in mpg regardless of how you drive it.

 

All this is why I'm currently in the process of ordering a GT35R for my car!

Stealth have got a lot of experience with turboed VWs dating back to the 90s, so you'd be in good hands with that kit :D

 

Stage 1 I reckon will be 10psi, which should be around the 330-350hp mark, depending on turbo sizing etc.

 

i am some what a new comer to the vw family, and this may have been asked more than once, but what sort of power can the rado take being front wheeled drive before the power becomes pointless?

i know theres all these new slip diffs and with out a doubt also depends how good a driver you are (meaning if your guna sit there with your foot flat to the floor with the wheels spinnig like a good un then thats your choice haha)

 

I don't think anyone cares what the limit is anymore :lol: Mainstream FWD hatches are now leaving the factory with 300hp, so in answer to what sort of power becomes pointless, how long is a peice of string? :D It all depends on - as you say - what you as a driver can deal with. Structurally the Corrado will take what ever you throw at it. This is no Corsa which rips it's inner wings apart after installing a Calibra turbo engine :lol: The Rado is made of solid stuff :salute: But limit yourself to 350-400hp (and similar torque) otherwise the gearbox can go twang quite easily after that.

 

but if 400 bhp is more than enuff, would it not just make more sence to get a rotrex charger, i know the power delivery is different to a turbo and turbos can give you a 1000bhp but if there both around the same sort of power would a turbo have any gains, which route would be less of a strain on the engine when driving normaly etc

this is a question as im still deciding which route i wana go in the near future well end of next year haha, and i know some people will be all turbos and others chargers, but if you could be impartial

 

Depends on the size of turbo you go for, aim to get a larger turbo that kicks in a little later than the norm, full boost around 3500rpm is a useful rpm to aim for as the car will have enough momentum to minimise spin, unless of course you run stupid boost.com! Don't forget also you can use programmable boost controllers to limit the boost to, say 8psi, in the first 3 gears and against throttle position and rpm, so there really is no excuse for leaving black trails behind you these days :D

Rotrexes can give great results aswell. Bobbi on here has a shining example of what you can achieve with a rotrex by using quality parts and good mapping (stealth). A Rotrex is a neat way around the heat and exhaust plumbing issues associated with turbos and it's cheaper overall I'd say, depending again on boost levels and other factors, such as reliability and longevity. Anyone can strap a blower to any engine, but few people can make it last 100,000 miles and make repeatable power, day in, day out. That's the bit that costs the most.

The Rotrex has a different power delivery to a turbo, so it all boils down to your preferences on the torque band. i.e. low and punchy, mid and toppy, or all toppy!

thanks guys for the replys

guess ill just wait and see what stealth put out and then go from there, its such a hard decission been changing my mind for a while already and i dont think thats about to change haha

thanks again tho

don't ask jim what power is ok in a corrado :lol:
