As per title im thinking and looking at 18xe/xe1 turbo etc, and Ive searched the net and found a few thread on Astra's and Vectra's, but im thinking make it your self budget wise, as im not splashing 4K with regal ripoffs!
Has anyone done a X18XE/XE1 Turbo??

Corsa VXR turbo/mani bolt up to that head ? That would be a good start
Would it not be better using a 1600 xe? Corsa vxr pistons fit then
Otherwise your looking at custom pistons or spacer plate
Maybe, just thought the X18Xe/Xe1 would be something different..
X18XE and the XE1 are different engines, first is big block, last is small block which is the one you want
Z16LEH turbo and manifold bolts up but they're not amazing and you're better off with a garrett imo, standard intake manifold is tosh so make your own up.
Standard CR is 10.5 to 1 so fine for low boost and the bottom end will handle 220bhp easily as standard. Despite the fact people swap out the rods as C16XE ones look bigger, the 18XE1 ones are sintered forged to give some idea of the potential of them similar ones in a VW 1.8T take 600bhp and about 9000+ RPM happily with much heavier pistons, so if you're looking for more than that just a low comp piston swap should suffice.
Management wise it depends how pikey you wanna make it, you'll need an AFPR anyway as the donor cars don't run one (its on the pump) so could use a rising rate, standard ECU's aren't the best for remapping and lots of them spit out their insides after a few months for some reason, so ideal solution is standalone.
The heads are awesome so you won't be needing much boost to get good power out of it with a half decent inlet, if you want to go over 7000 RPM though some work is needed as the gearbox's spit themselves out and the valves fall apart around there.

The 18XE is a longer stroke so should be a taller block. I am sure the rods are the same as an X16XE so if you were to replace the crank with an X16XE one would you not lower the compression enough to enable a turbo to be bolted straight on. Although it would no longer be 1800cc it would still be over 1700cc I would have thought due to the 1.5mm larger piston than a X16XE.
Might be wrong, just thinking out loud.
16xe crank should fit if you wanted to go that route as well. I've come across a build before that was 18xe1 bits in a 16xe
Guy on corsasport does Z18XE turbo conversions £3000 drive in drive out.
The kit will fit the X18XE1 too.
So MK your saying i need the engine out my Astra cobbled together with 16leh inlet a garrett turbo, and say a Dblis flowtec type inlet, slap on some ARP rod bolts, then find out the best ECU set up to go for?
Humm price for all that, if i use my Astra engine?
Did you miss the bit where Scott was saying he wanted to do it on a budget ?Originally Posted by MK999
Corsa vxr turbo and mani can be bought new for £400, ALOT less thank a Garrett and custom mani, plus who says the units are crap?
LOL i would do that if i was going to use it in my Astra and keep the car, but not if im planning using this engine in the Saloon..
