could i add a turbo...???

esta · Post by **esta** » Fri Feb 23, 2007 9:44 pm

Hi all!

I have a 2l GT and was just wondering how easy it would be to add a turbo? What (recommended) models are there?

I had considered getting one imported from Germany where the 2 litre turbos were sold...

Most importantly would it fit? would the guages work and fit in easily?

I'm 100% new to any engine modding so ALL replies will be worthwhile trust me!

Im not in a hurry i just wanna do all my groundwork before rushing into it and messing it all up lol!

Well cheers then

yes and one guy has (tobi480) and another failed.

loads of money / work. fit a b18ft and rich mod it.

btw was no 2lt turbo from volvo sold. volvo found they went bang and never sold any.

Was that because of overheating problems then? I know the cylinder heads/combustion chambers are a different design/shape on the 2 litre engines, hence they're supposed to be smoother running. Or are the engines just totally different?

On another note, I wonder if anyone has ever bothered boring out a B18FT. Would there be any point, or would it just be a waste of time? I suppose custom pistons would be needed. But the ECU would be able to cope with it, wouldn't it? Only thinking as that would surely mean less boost would be required for the same power output, so perhaps reliability could be better? Anyway, I digress! From what I've read it seems it would be easier to swap the entire engine for a B18FT than retrofit a turbo to the 2 litre.

Was there really no 2l turbo? I was under the impression that there had been one

Maybe one or two. AFAIK Volvo did experiment with it, but never released it for production.

hmmm, thats my plans scuppered!!

would you b able to fit a modern volvo 2l turbo?

Or even fit in a whole 2l turbo engine? would it be compatable?

I have a GT and if that is possible I would love to know so I can finally have that turbo that i am after..

Some insurance firms when you fill out the make and model of vehicle they ask you if it is a 2.0L turbo!!

If you are going to turbo the 2l then you will be wanting the older oil eating engine (red dipstick?) not the new one (green dipstick?).

The older engine has oil sprays to cool the pistons, the late engines do not have them (removed to reduce oil burning).

Without the cooling the pistons may well melt. I don't know if the cooling jets can be retrofitted, but it may be possible.

Hi,

my 2L engine has the oil sprays to cool the pistons,

I also donÂ´t know if itÂ´s possible to retrofit them cause you would need the oil feed lines for the cooling jets and I donÂ´t know f the newer version of the 2L block already had them.

Also a little bit of piston machinig is needed to reduce the compression, and many other litte things need to be done to "turbo" the 2L engine.

It is not a job done in 2 days ....

Cheers

I wish it was a job that is done in two days...

that would be fantastic. unfortunatley they dont make it that easy hey

.. I have the green dipstick so i presume then that i have no hope at all of having a turbo unless it is professionally done.

and not a bodge job by me

just kidding. rather the pro's did something like that anyway.

best of luck with them. cant wait to lay my hands on a turbo 480 not had the privilage of driving one.

.
take care.

i recon it would be 323243987209374million times easier to swap in a turbo engine than try to turbo the block you have.

but then easiest isnt always best?

I've got an oil eater (yes- the red dipstick), and after a lot of pondering I am going to try a little supercharger on it. Start off with a really low boost (4-5 psi) and gradually work up to the safest maximum pressure

, probably 6-7psi??. Alongside the piston cooling jets, I will have an intercooler to cool down the forced air and an oil cooler to help keep those jets spraying cool oil to the pistons-which should all help to keep detonation at bay... I have read that the 9.5:1 CR of the 2.0litre is borderline for boosting. i.e- anything above that and you need really low boost, anything below, and you can use a fair bit. Ill let you know how i get on. If i cook the engine-its a lesson well learnt- and an excuse to plonk a 1.7turbo in

. We will see how the ECU copes too.
If the supercharger is unsuccessful, its not wasted money, as it can go on my manta

I think you'd need to install the engine management system from a turbo in order to do what you say.

I don't think the 2.0 siemens system would add extra fuel to make use of that boost.

Retrofitting the LH / EZK isn't so hard. The engine swap guide tells you how to do the most of it. You need the Turbo sensors and throttle body, but that's a plus anyhow as the intercooler and pipework will all line up. If it doesn't work out, then it's all the easier to drop a turbo engine in there

If you are in the UK then I can tinker with the ignition timing to suit the engine better. If you want to get some time on the rollers, then it should be possible to make a resonable job of it. I would think that 8 - 10 psi would be possible with standard compression (considering the turbo engine will go to 27psi without reducing the C/R).

You could get 7-8 psi worth of extra fuel by increasing the fuel pressure. It would be possible to upgrade injectors later.

So what would need to be done at the minimum is...

Fit Tubo ECUs and sensors (make sure it's a dual layer ignition ECU)

Fit the intercooler

Get an adjustable Fuel Pressure Regulator

Fit the supercharger and connect it to the intercooler at one end and MAF at the other. This may be the tricky part

Im in manchester, and would like to sort someting out.

If i start getting the parts together when im closer to having everything, ill start hassling you

. But first things first-MOT!

and she smells like she's running hurrendously rich

, so gotta sort that. After all that ill gather the parts.
Thanks for everyones input.

Hmm I think the injector upgrade isnÂ´t that easy as the B20F engine has side feed injectors and it is not that easy to find upgrade injectors which are a straight swap. I had to make some adapter plates to get the "standart" injectors installed and also a thread at the head has to be made to get the fuel rail from the B18 bolted onto the head, and even the fuel pressure regulator is another one at the B20 fuel rail.

Cheers

Nothing like a good challenge. And I do realise that it would be much easier to put a B18FT in, but its even easier to go out and buy a T5 or mondeo st220... I just love my engine- and to make things difficult for myself lol.

There's an intresting supercharging thread on this forum (about a year ago)
Up to 5 psi you could use a rrfpr. If you want more them a conversion to LH-tronic of a turbo is the easiest bet. Although it might be possible that a ECU from a Renault 21 Turbo will fit the std loom. Never checked it.
