Pushing over 370bhp but what's with the rpm cut off? http://www.alphafabi...otec-turbo-kits

[Mopeytitan]

Bolts some of that on an sc and you've got more power than you can shake a stick at

[Nev]

Our American cousins seems to be able to be able to squeeze 1400 BHP out of a "humble" 2.2 NA ! Anyone who choons his VX220 to that and can actually press his accelerator to the floor withour fear will be welcome to a crisp £20 note from meeeee !

its that better bhp / £ than a SC conversion

[techieboy]

Who cares? You'd still end up with a shitty turdo'd car that you could already buy if you wanted to.

[Exmantaa]

Besides the problem that that kit/manifold doesn't fit at all in a VX220...

 

Bhp (above 250)/ £ can be better, but R&D effort /£ probably not.

[siztenboots]

your are probably right about the uncosted time and effort , when you can get a factory turbod b207

[Exmantaa]

Well, you can simply bolt-on the factory turbo gobbins of the latest DI 2.0 LNF/NHH) engine onto the Ecotec head. But not in a VX without sacrifying your boot space. 

 

Currently looking into a turbo conversion for someone and already spending way too much time on R&D-ing a suitable manifold...

You reckon it won't clear the chassis?

[Exmantaa]

Most likely that one will clash with the rear subframe and for sure it will with the NA boot...

[Rosssco]

Since superchargers are soooo 2012, I've been thinking I'd like a B207 / Z20 with the LNF turbo set up attached, using the LSJ manifold as a well trodden chargecooler option.. http://www.cobaltss....f-parts-267737/ Should be very responsive (perhaps too responsive) and should, be good for 300bhp / lbft easily with a good exhaust.. Used LNF turbo bits are cheap in the states..

[Exmantaa]

Very responsive (dual scroll turbo), only the minor issue that it will not fit into a stock NA...

Think the actual turbo will clear the the subframe, but the exhaust elbow / down pipe won't fit of course - something custom required there certainly..

[speedster]

Space is a premium but there is some. Even the afi kit might squeeze in.

[slindborg]

atleast its not dilbert stuff

[siztenboots]

get rid of the bulky precat and it will fit , remove the bolted on turbo intake pipe extension as well

[TFD]

You have to go down with the turbo to make it fit (NA trunk that is).

We're figgering out how to make an affordable and good manifold and then.... Turbo's for the win!

[Rosssco]

The boot will have to be chopped, almost inevitably, but if you can keep the turbo outlet below the level of the cam cover, you should be able to avoid messing with the boot lid drainage channel and catch, so just reshaping the inner profile of the boot - a few like Vocky have done this for different NA manifolds.

 

For big turbo's yes, a different manifold design maybe, but I highlighted the above LNF (or current Astra VXR, and other Vauxhalls) as it comes with a completely bolt-on option with a twin-scroll manifold / turbo design, and all the coolant / oil lines ready to go. You could also in theory go fit something from the likes of ZZP which are designed for LSJ's or Z22's

"[font="Arial;"]The stage 1 kit utilizes a K04 turbo found on the 2.0 LNF. Stage 1 has instant spool and power at any rpm and adds approximately 100 HP to your car. The turbo is capable of more but higher octane fuel would be required as well as engine modifications to hold that level of power increase. On conservative builds, target 200WHP and 5psi of boost. The 2.2 should not be run at over 5psi in stock form[/font]"

I dont want to chop my boot and if DBilas can make a working manfold...

Either way (big or small turbo..) You have to chop and/or customize.

[slindborg]

I if DBilas can make something fit that gives not much gain but they can charge a fortune because they filled in the TUV forms
