The cheapest and easiest way to mount a pair of turbos to the X30XE engine would be to fit them to the rear of the exhaust pipes and route the boost back to the engine. This way you don't require expensive custom manifolds, you don't lose room in the engine bay and engine bay temps are also kept low. The are plenty of off the shelf kits for Corvettes etc. Have a look here for example: http://www.ststurbo.com/ it's a proven method that has been used on lots of cars.

   However, the inherent weakness in the X30XE (it's not designed with sufficient cooling ability to take considerable power increases) means that I'd imagine you'd still be far better off swapping the motor for something more suitable for big power in the first place.

Ah yes - those remote mounted turbo kits that have so much intake volume to compress thanks to the long intake pipes that turbo lag must be measured in days

[TECHNOPUG]

Nonsense.

Providing the correctly sized turbos and intake piping are used, lag is no more of an issue than a conventional front-mounted turbo.

[2woody]

hmmm.

lag is caused byht etime it takes to compress the amount of air between the turbocharger and the engine.

more air = more lag, even with a properly-matched turbo.

why turbo/supercharge you v6 when you can put a v8 in there a lot cheaper. Its cost me £2500 to get my dream omega together ls1 5.7 v8 and blower mot'd monday taxed and insured and ive emptied 3 tank full fuel so far the look on peoples faces when they see what havoc i can unleash on other performance cars egos and there owners  PRICELESS

oh yes forgot to add took 6 months of hard work to sort it all out and deep pockets to run, super unleaded @15 miles to the gallon when having fun   

[Liam]

I agree entirely! Wow how did you even get the parts for 2.5k!? Good job. Would probably cost that much to stop the V6 exploding/melting if it was putting out anywhere near that amount of power. I may have said this one or two times already, but I'm dying to check out your car! And when the current project is finished my own meggy may very well take the same kind of steroids.

I put an X30XE in a Ford Kak a while back but after getting bored of it I started a turbo conversion, it's not back on the road yet so I can't say anything about it's reliability but I'm hoping I've taken the appropriate measures to not blow it up!

Due to having no room left in the bay I've put the turbo in the boot with it's own oil supply (to save the engine should the turbo s*it itself and not wanting to put any stress on the standard oil pump), intercooler etc.






I'm running Volvo t5 injectors with a 3.8bar FPR which should fuel enough for 400bhp which means running at 320ish (desired figure) it'll be safe, I've ghetto decompressed the engine with spacer plates (down to 8.5:1) and have installed aftermarket management


I've got a hole in the bonnet with a scoop underneath to direct air over the rear manifold and I binned the standard oil cooler and made a remote one with an oil cooler from a scrappies and had the hoses braised onto the oil pipes near to the filter on the engine

Hopefully with all this lot done it won't blow up! If I was stupid enough to do another one of these then I'd base it on the Saab v6 turbo engine as they have under piston oil squirters and stronger rods but by all accounts it's still not a "strong" motor.

Another thing I will say is I've heard C20/Z20LET pistons won't work as desired as the valve cut outs are wrong however Z20LEH pistons suit better but that's just what I've heard

I've also got a very large capacity radiator hanging out the front, it's 1.5x the capacity of the vectra v6 one




If it's in a FWD then the remote turbo should work well knowing the problems the x30 motor has, if it's RWD then I'd agree with omegadan67, just put a v8, a bmw 740 v8 even fits in a Ka engine bay lol




It's not an Omega but would need the same work to do, everyone needs this in their life: http://www.youtube.com/watch?v=f86bsY1Iv9I&feature=search

[Martin_1962]

For that amount of work I would have RWDed the Kak, easier to get at bits then, and as you said drop in a V8.

It would have been worth it for the handling alone.

[Liam]

Cool project! Out of interest what made you go for the vaux engine instead of keeping it the family and using a nice ally ford V6? How thick are your ghetto spacers? Did they not cause the coolant bridge and inlet manifolds to not fit on properly, or did you just get away with it?

[philhoward]

Is the red Ka cheating though?  That looks like a Scimitar chassis to me...

[Lazydocker]

Cough Cough.... Housekeeping!

Cor, it's a bit in here..

(I know, the joke is all played out now, it took me a while to find a picture )

that what I get from my V6 some days
by the way
any chance to come and have look you project??
