C16xe and X16xe throttle boddie....

[boyd_1989]

Appart from the throttle linkage, what's the difference? Or are they just the same?

Also, is there any modifications you can do to make them better?

Thanks. Craig.

I've had (might still have both) and yes they are largely the same. What do you mean by better?

I don't know really, but I'm just trying to think of some possible cheap ish mods. And ah ok thanks, I was just wondering cause I have a c16 but with a powerbox so I had to use the x16 throttle boddie. Tried to use the c16 but the throttle cabble was really tight. So if I was to use it I'd have to adjust something to sort out that.

From what I remember there is no meat to remove, nothing on the butterfly to remove so pretty much stuck with what is stock. What I will say is that mine did alright with the Velos setup with a standard TB.

Use whichever body fits right with your setup if there is a difference it'll be so slight as to not matter. There's loads of other things to do with the engine/ECU before you start looking for fractions of bhp.

Had a look in the garage and I don't have the two throttles anymore but had a look at EPC. The basic body is the same, the X16 linkage needs a cable with lug on the end as it fits into a plastic carrier. The C16 linkage is like the older Nova engines with the ball fitting. Both use the same TPS and idle control. Other stuff around the TB does differ but you'll have junked it all for the powerbox. OpelOEM links:

As mentioned above the use different cables

[boyd_1989]

I know about the cables. I have tried both boddies and the c16 doesn't work properly so I put the x16 boddie back on. What I've done so far is: c16xe with F15cr, powerbox, gte / gsi flywheel and clutch, 4-1 with a magnex 2.25 sysyem. Standard c16xe management though last time I tested on rollers I got 134bhp got a pic to prove! Do you know where I can get a chip for the c16xe ecu to raise the limiter? No one on here is selling any and I really need one. My power when on the rollers was still climbing so there are a few more to gain just from a raised limit.

Thanks for your info.

but the remap may shift/upset your power and torque band as it is currently. Ide recommend ARP bolts on the con rod caps if going over o.e rev limit.

You can knife edge the butterfly to allow better airflow over the butterfly.

You can also remove half of the spindle that holds the butterfly in place and then file the other side down to allow more air into the engine. These mods are for the seriouse tuner though lol

Not sure in hp gains but we used to do it in a strict class where every little gain helped.

Don't forgett loctight if your feeling brave.

Bit like this matey, horrible photo but you can make out what I mean.

Hmm hopefully not, I've heard of a few people with same mods have their limit set to 7200rpm I'd be happy with that. And yeah I forgot about the ARP's will have to add them to my list. Thanks

Thanks mate, I may do that in time. Would you say its pointless? Or would it be worth it?

[16xe_chris]

I wouldn't say it was a pointless mod it's just another one to add to the list.

I can't remember the exact gains as it was just another mod to the list of many, you can polish it up as well to make it smoother, similar to porting your head.

Mine (X16XE) has the power box type inlet manifold, 4-1 zorst manifold, mild steel 2" system, GSI flywheel, +1mm pistons, cone air filter and an adjustable fuel reg. This gave me 122 horses on a reputable rolling road. Without the raised fuel pressure the car ran like poo (jerky in 1st gear crawling) and ran too lean. Perhaps getting your fuelling spot on might be your next step?

My c16xe goes really well with these mods so far, I just want a bit more. I thought about putting a adjustable fpr but few people on here said not to bother.

Good point, cheers mate, I will add this to my list, I do have a few spare TB's to play with.

My C16xe:
Mods....
Powerbox
4-1 Manifold
GTE / GSi Flywheel and clutch

Headwork and sharper cams (or even just inlet) would be my next step

Deffo head work next. The cams aren't worth upgrading unless your going to pocket the pistons and do it proper. You would get more benefit putting the likes of a DTA on there than cams on standard management.
