C16xe Turbo

[Jayz Nova]

What sort of power can be made from fitting a turbo onto the 1.6 corsa sport engine, I have in mind forged bottom end, polished head, cams, performance inlet, turbo ect what gains can be achieved, I was looking into a c20let but there's not many of them for sale now and there a little bit common.Jay

Given the VXr 1.6 lump can be squeezed to 250bhp, that's your target lol

[Mieran]

I have an over sized block (0.5) with forged pistons and arp rod bolts, pm me if you're interested

I got told the corsa vxr turbo fits the c16xe

[Nova-nation]

Personally, I would just put a 1.6turbo corsa Vxr lump in instead

It does.... But its not as simple as that.
When I start my project thread, you'll see exactly how to do it and the way I'm doing it actually works.

but it is as simple as that though.. ok, the pipes & wiring need work to make it run, but it has been done quite a few times now, and the engine is way newer to start off with, and won't need much work, whereas a c16xe will need a full rebuild, obviously the turbo setup & then the problem of the mapping needs sorting.

He said about the vxr turbo fitting on a c16xe I said it does fit but not that simple, as the oil filter is in the way of the exhaust side of the turbo. Just saying that you will need to modify a few things to make it work.

I plan to use the VXR turbo corsa set up and turbo a x16xe I've got most parts, I need to sorce a oil filter relocation kit, a compression spacer plate, and rising rate fpr an then see what can be done, won't b straight forward but should be fun lol

[mowgli]

scott, shorter rods would do the compression drop .... like maybe 1400 rods..

[scott.parker]

What's Cheepest an easiest will be done

[Stuart]

Sorter rods might ruin the rod ratio, and also leave a too big a combustion volume with ballsed up squish.

[mowgli]

in fact, i think you'd need rods from a larger stroke engine, like the z18xe, as they'd be shorter...

stu, if you got the right rods though, its got to be as good a solution as slapping a spacer on, if not better, as keeping the head in the right place solves all the cam timing issues etc.

[mk1nova_rich]

I was under the impression that Z18XE and C16XE rods are the same dimension but the latter are actually stronger?!

[novalovingned]

If it's a Corsa sport engine it won't be a c16xe ;) anyways, like said I would use the Corsa vxr turbo with oil filter relocation kit.

Scott: don't bother with a spacer, just run it at a lower psi and hope for the best lol. Oh and your old track car was at knockhill last weekend, supposedly went well :)

[Stuart]

Nothing wrong with running 10:1 compression and boost... Just put management on and be happy

[mowgli]

and there is the stumbling block.....

'mapping' still has a terrible reputation.. with stories & blown up engines etc..

is it timing or fueling that needs work, or both??

[Stuart]

Both and also the airflow needs controlling (boost control if you like the lowest common denominator term) properly too.

Calibration isn't hard, it's just 95% go for max powaaaaa rather than longevity for the sake of a few bhp off the top line.

[Jayz Nova]

Think I'll just go for it and turbo a corsa sport engine, I can get some of the engine stuff done at work like oil squirters and fly wheel lightend ect

there was an a16ler block on ebay not long ago, i was tempted but i already have 2 xe's in my workshop lol also i think colin smith is still trying to get rid of that 1.6 VXR engine he's got, been on ebay 4 times now..

[MK999]

I was under the impression that Z18XE and C16XE rods are the same dimension but the latter are actually stronger?!

Same dimensions but although the C16XE rods are bigger/meatier the X/Z's are sinter forged, similar dimension rods take about 6-700bhp at 8.5-9k RPM in the golf 1.8t's I'm informed. Not tested them but I'll be running the sintered rods in mine over C16 ones.

[mowgli]

so are the 1.8 pistons shallower crowned? to cope with the extra stroke, or is the block taller?

[MK999]

It has a huge combustion chamber due to the valve angle, the piston clearance is actually tiny and really restricts cam lift/compression without going to forged pistons with a large dome and cutouts.

[mowgli]

so it is a longer stroke engine, thus it must have shorter rods, or they will push the pistons out of the bores...

[MK999]

Never had the two side to side to compare, the pistons are a fairly short slipper style design so they may be shorter than the C16, C16 may not hit the top of the bores and have a smaller combustion chamer. Reason the compression isn't massive on the 1.8 is the chamber volume though.

[mowgli]

c16 ones do hit the top of the bores..

[MK999]

That leaves pistons as the only possibility then.

[Jayz Nova]

What can a 1.6 engine be bored out to and what is the reason for boring engines out can I achieve more bhp ect
