There's not really much room here



So I'm going to locate the turbo in the boot, I'll be using:

An externally gated t34 turbo


With an oil scavenge pump to feed the turbo


..from a little harley davidson oil tank which will be mounted below the turbo to drain


There's not a lot of room under the car and it's bloody low so I'll run 2 x 1" boost tubes from the inside of the boot under the passenger seat and through the footwell into the engine bay, collect it there then run a 2 or 2.5" pipe to the MAF


Where the middle box joins to the rear box I'll modify to take the exhaust up to the turbo then back into the back box to keep things simple


I have a 2wd Saph intercooler somewhere I might use, I know most people don't one when using a remote turbo but they have the benefit of cooling from running the boost pipe underneath the car

I've won the pump and tank on ebay so if they turn up before the weekend I'll get cracking, when I work out what I need to do with the exhaust I'll get some 2" bends and hopefully get something half plumbed in within a fortnight

Good golly!

Not seen a project like this before. Please keep the updates and pic's coming

there is something missing up stairs with you lol

TurboShed

Yep you need your head looking at mate

Shonky

Haha, you know I get bored too easily!

Jonzy

The ADD/ADHD way!

williamson

sounds fucking nuts! only thing i will say is is the pump gonna be able to pump enough oil to the turbo to keep it happy? can u not run an oil line from the engine and then use the scavenge pump to pump the oil back to the sump?? im sure ive seen this set-up before working well.

Crazy project!!!!

Shonky

I felt happier keeping things seperate as not to put extra strain on the engine and allowing more more control over the whole setup, it's really a finger in the air evaluation!

The particular pump works at 2 bar and will flow 28 litres per minute, I don't know if that's a lot or not etc. but 28 litres sounds a lot and the turbo will see far less temps that if it were on the manifold

AzE_B

lol this is mad

what boost will that engine take

Shonky

I'm going to try 5-6psi, I want to prove the setup on a standard 2.5 (with standard CR to keep things simple and cheap) so if it breaks I don't mind replacing it, the goal is to build a low compression motor based on the 3 litre omega unit next year and use aftermarket managment

I don't care much for power figures, I just want something that goes like fcuk on the road

I am a big vectra nut and hope you know that turbo'ing the vauxhall v6 won't work at all. The rear bank gets to hot as standard and turbo'ing it will just keep melting the rear bank. The best way to get power from these motors and the cheapest is supercharing it.

You can use a supercharger of the new mini's with a few custom brackets and omex standalone management. Can get more info if you want from people who have already done this conversion if you want.

But this deffinately will not work especially with the size of the bay and the amount of heat the engine produces as standard.

AzE_B

have you any links mate

RUSSELLB1904

I can get you links but there off a owners club forum and you might have to be a member to view.....

AzE_B

im a member on the vvoc for some reson

Shonky

With the turbo being in the boot what's the difference between boosting it with a supercharger or a turbocharger? both produce no heat (in this case). I'm also already ducting air from the bonnet over the rear manifold to help as I know it's a weakness

The charger from a new mini probably won't push enough air, they only rate them for up to a 2.0 displacement though I'd love the sound of one there's really no where to put one

RUSSELLB1904

This guy fitted a supercharger....

http://www.vvoc.com/forum/showthread.php?t=124814

Never herd of anyone turbo'ing one tho.

Might give you some idea's on getting rid of the bulky plenums at least tho if you go the turbo route which will give you more space in the engine bay.

Someone has also fitted 6 throttle bodies on one aswell (or still in the process) if your interested in that too.

Dan1281

this is fantastic, i'm loving the stand alone oil system for the turbo

RUSSELLB1904

Other things to look at to get more power, but don't expect huge bhp increases are custom manifolds, equal length downpipes etc, then you need to look at the injectors and what they flow to make sure the engine does'nt run to lean.

The most psi a standard engine can take is around 6psi, anything more then you have to start looking at upgrading the engine components. You can use c20let pistons in the v6 but obviously you'll need to buy 2 sets or get some custom made, then the crank upgrading, oil spray jets and more.

Can end up spending a fortune for just a little power.

Get the turbo set-up built and running on the 2.5 lump then fit a 3.2 block out the new vectra's. All you'll need is the block and heads for the swop.

AaronsKa

get it down a strip first! before and after runs

AzE_B

can you get big power out of these v6s

it seams like loads of money and hard work for not alot of gain

Shonky

That's impressive!

There's no way I'd fit a turbo or a supercharger in the bay, there's just not enough room!

It's a turbo I really want Do you have a link to the throttle body build?

Shonky

The 3.0 build would use LET pistons, I found out they're the same diameter which makes it cheaper than custom ones, I'm not spending big money on it, I'm just trying a few things out

I've been told 6-7psi is the limit hence trying something a little under for now on the standard pistons and compression ratio

I had thought about the 3.2 because of the base power it produces but if the piston diameter is not the same as the LET I'd be spending a lot on pistons which I don't want to do and the 3.2 itself isn't going to be cheap

RUSSELLB1904

Here's the TB project thread....

http://www.vvoc.com/forum/showthread.php?t=192013

I think you would deffinately benefit from making a custom inlet of some sort to give you more space and clearance in the engine bay tho.....

RUSSELLB1904

Things which you could custom make yourself like the custom inlet manifold and larger TB would be a good cheap mod, a de-ridged throttle body with a larger butterfly can be bought on an exchange basis for less than Ł50 which is good, then blank of the egr valve by simply fitting a blanking plate or 5p coin i think fits in the hole.

Fit a oil catch tank too as the plenums get filled with oil due to the oil breather pipe which runs from the right side of the engine across the top of the front bank and into the throttle body on the front.

Few of these daft cheap mods don't have make a diffence and help you gain a few bhp here and there for a few hours work and less the Ł100.

3.2 pistons are deffinately bigger and different than the 2.5/3.0 ones but i think not 100% that the heads are all the same tho.

Shonky

I remember seeing some 400bhp N/A motor somewhere, I can't imagine there'd be much change from 20k

Im not looking to get masses of power, Im sure 300bhp of v6 turbo in a Ka would be quick enough for me

Shonky

Sounds spendy!!

Shonky

Cheers for the steer!! I'd consider a custom inlet and larger TB on the 3.0 build so I can make the most of the turbo etc., it'd have to be tappered and shit but that's food for thought down the line

yes mate, another mad addition, look forward to seeing it complete

Shonky

I'll give you a shout when I'm up your way next. And I definately needed that servo and master cylinder!!

Fook, this will be funny to see! Good luck

Nuts, but looking forward to seeing the end result

Cool project.

I went out yesterday in a Tigra V6 using the same engine, but fitted with a supercharger.

The management light was coming on as soon as you went past about 20% throttle as it was running off the end of the map (he's going to put it on aftermarket on it, he was just showing me what it went like for now) but providing you kept it within the map, it really did go like fuck, must have been at least 250bhp the standard management could cope with, so I reckon if you keep the boost low on your setup, it will work fine without needing aftermarket, so good for now.

Shonky, ignore all that totally, waste of time on a turbo.

The standard V6 thottle body flows about the same as an RS200 one, you will NOT find it restrictive on your project.

Shonky

Cheers Chip

I have an un-used SMC in the house so you might get roped into mapping the 3 litre that at some point!

andy.mac

will this not have alot of lag as turbo is in boot

cool project tho

the way its being done wont increase the engine bag temp any more then a supercharge would neway. if the back bank gets too hot then any sort of force induction will give rise to the same problems.

Great project and well done for going against the grain. Too many people are quick to put different things down without trying them!

Where did you get the wastegate take off/spacer by the way?

Shonky

There's a guy with a remote turbo 205, he didn't have any lag, he used a roller bearing turbo
