X18XE1 fitting

[John]

Hi peeps, there was a good thread about fitting these recently, was it on c/s? link me up as i can't seem to find it lol:d:):thumb:

[Mieran]

some info here that might apply to a nova

[John]

ta mate, that wasn't the one i'd seen but quite useful all the same. Rep left :)

[Edd]

Ahh nice one

Been looking into this as well

[John]

i reckon one will fit nicely in the loon lol

[mowgli]

there was a huge thread on mig iirc, a corsa b with tb's... not that i frequent the place

Dave Franczaks old corsasport thread (cant seem to find it now, but its a years-ago thread) was the best ide seen that showed a small block 1.8 into a nova/corsa b; keepung o.e management and inlet etc.
Warren G did one a bit ago in his thread here: (corsa b again, but same as nova really)

Theres a few with ITB's, as mowgli mentioned; are you going with itb's or keeping o.e induction..?

[John]

I'd want to keep it on standard management, just transplant the whole lot out of the donor.

yep it a good idea cheaper than any x16xe or c20xe and you don't have to be a gay big block owner lol. that why am doing it. alex w made a good point if you run a x16xe sump and oil pic up you can run a corsa 4-2-1 or 4-1 manifold witch makes life a lot easer and cheaper.

what engine did you get the tb's off as i cant fined them any were for a x18xe1 am probably not looking hard enough tho. can you use x16xe tbs on them

An x18xe1 engine isnt cheaper than a x16xe particularly.. i also think its a trickier conversion; a good example is the one way fuel rail that x18xe1's seem to run.. It wont just drop in; do your 5 wires py pass immobiliser and away you go.
x16xe sump will fit; but not without some baffle modification/removal. Again; it wont just drop straight on. Hopefully you can do this whilst the engine is out, on a stand.
I agree having the choice of the x16xe manifolds is much better than the limited x18xe1's available, youll get better, more types and brands for your cash - often the same or more money. But again its no cheaper.

dBilas do free-flowing inlets/throttle body applications for the x18xe1 - but circa £500+ there is a copy on ebay, £300 ish, but not sure how that faires.
Mark is running ITB's off an o.e toyota engine , attached to a custom manifold to fit the x18xe1..

Anyway john ill try find that old franczak thread it was almost like a step by step guide, but as said was a while ago; bout the same time i bought my z18xe lump.

[mowgli]

i think for me the attraction of the completely stock x18xe1/z18xe engine is, for example, if you get a good veccy sri130 lump, its going to be worth the aggro of fitting it to keep it as a std reliable engine for way less money than trying to get my e16se up to 130hp, and if you keep the cat, it could be used to get the emissions down & thus lower road tax, london future LEZ emissions rules etc, and also the parts availability is going to still be easy for a good while.

[peester]

hey, totally agree - hence why i did it. Not so sure about the emmisions thing tho lol..
To get a Z18xe (the sri 130 lump) working in a nova/corsa b etc - youu need to remove its inlet and throttle body (flyby) and swap with a x18xe1 one (cable) maybe ecu/loom changes too??
I think best stick with the x18xe1 (115bhp) and just get the cams reprofiled (£150ish?) you should see nearer the 130bhp then; with less faffing..?

[mowgli]

you may not be sure about emissions, but its coming.... they just haven't told us yet... they are screwing us for £5k per truck for exhaust filters....cars will be next.

[peester]

hmm. well anyway. until then..
Ive found the thread i was on about john, but its too old dead links. Feck.

[Adam]

Only post 2001 cars (iirc) have road tax going off emission levels?


Cant really do that on older cars, especially very old cars. So i cant see there being much a change to the emission rules regarding 20+ year old cars?

On trucks/commercials etc, fair enough.

[Mazz]

I always thought emissions went on what was oldest, the car OR engine. So a X18* in a 1990 Nova would be ok with no CAT. But then again, do they have a lambda after the CAT? that might bugger the fuelling up slightly?

[Adam]

Just get a 4-2-1 on there.

And they do on whatever is oldest, its in the mot manual.

[peester]

No one to my knowledge does a good 4-2-1 for the small block 1.8's. All 4-1's only.
Unless aforementioned sump swap is done then muchos choice x16xe 4-2-1's.

[Mark]

No one to my knowledge does a good 4-2-1 for the small block 1.8's.

Lexmaul....if your rich.

[peester]

ah yeah, quite right. well done.

Could get a welding course, a welder, a book on exhaust tuning and make your own for less than that lol

[peester]

And it still wouldnt be as good or worthwhile lol

If its a quality item, then thats not a bad price, lifetime guarentee im sure..
Its rang a bell now; i looked at getting that lexmaul item once upon a time but ended up getting piper 4-1 jobby as could buy it with 15% discount on a buy now pay later, from old workplace.

[John]

sooooooooo, the x18xe1 only made 115 out of the box? i thought it made 126 in the astra sxi/sri or vectra sri?

[Mark]

nope, but it will with z18xe cams...

[John]

And i presume it's only an x18xe1 if it has a throttle cable?

[John]

nope, but it will with z18xe cams...

ok cool, so that's the only difference? the cams? do the z cams run ok on the x managemnt? :)

[peester]

sooooooooo, the x18xe1 only made 115 out of the box? i thought it made 126 in the astra sxi/sri or vectra sri?

the astra/vectra sri/sxi have the z18xe; so thats 125bhp.
x18xe1 was fitted to low spec. 1.8 vectra/zafira etc.. hence 115bhp.

Im not sure how youde get on with the management tbh; hence suggesting keeping it all x18xe1 and just get the cams reprofiled and ecu maybe remapped - might even see over the 125bhp..?
Mtech in netherlands do great-priced ecu chip and other mods for the x18xe1. See autosprint for the cam reprofiling.

Yes - only x18xe1 if with throttle cable.
I think people on vvoc have tried a z18xe, then replaced the inlet and t.b with a x18xe1.. not sure though.
As you know john, i didnt have to look into any of that with mine..

[John]

ok i'm a bit confused. I've seen 2 x t plate astra g's, one sxi, one sri both with an x18xe1. (throttle cables can be seen in pics) so these are deffo 115bhp? when i'm ready i'll probably get a whole car and swap it that way. (5 stud hubs would be handy too) Thanks for your help Dave and Mark :)

[peester]

yeah that wasnt bible, just the ones i knew of or thought i did - seems maybe more dependant on year of manufacture..
but yes x18xe1's are slightly lesser power than z18xe.
Ah cool whole car, good idea.
