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! lol

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? lol
Best check out how much a decent T25 can be had out of an S14a then as I've seen them for a lot less than £400. Given they will do a range from 180 to 280bhp happily compared to the 200 to 240 or something the crappy KKK thing with it's cracky cast manifold can handle, I say they're crap compared to a good T25.
Making up your own inlet is time and some cash in materials, depends how much you can find a tig welder for but if you get stuck I know of one that works for about £25 an hour, so about £100ish for that.
Exhaust wise you might be able to use the standard manifold and a flange for ultra budget, but I'd use an S14 fancy or even standard manifold and lop the flange off for a new one, so you can get that with the turbo for £250-300ish for a recently refurbed unit.
Engine and rebuild parts with the 16XE crank if you wanted to drop the compression a bit, about £600 or so (engine 200, parts £3-400 and a crank say you had to get a bottom end to get hold of, £100)
Then a good AFPR, management and a good mapping session is the major expense really, probably about 1500+ for all that.
So that puts you at about £2500 or so plus odd consumables etc.
A T25 out of a 15 year old S14a is not going to be decent imo
As above. I looked at the compressor maps, cost, availiability and reliability issues of both, and for the range of power you can work an x18xe1 turbo to with limited mods, the T25 came out on top for availability, reliability, cost and power potential/suitability.
So a vxr turbo/mani for £400 is going to be cheaper then?
According to my maths £250-300 is a lot less than £400? When I was looking at prices I actually saw one sold on a manifold for £180 so that's a conservative estimate. If you factor it in the 2-3 replacements with cracked manifolds over the lifetime of the car (Which you can't replace, they are part of the turbine housing) which is quite common with increased performance standard VXR turbos, probably something to do with that power range I mentioned earlier being exceeded, it's a hell of a lot less.
By the time you get a custom mani done thats going to be over £400 for sure
Havnt seen loads of reports with cracking like the early Z let mani either
So that mani will bolt straight on to a 1600/1800 head then? Im thinking not, therefore the mani will be useless
I'm not gonna carry on searching back and quoting my posts lol Somewhere up above though it basically says: "Cut flange off, put new one on." It is entirely possible it needs a bit of bending or extending before you can use it as I only got as far as comparing one on a friends S14a to rough dimensions, but it's 95% there and very much a viable option.
If you really want to build one with the standard KKK turbo and manifold no one is stopping you, I'm just giving Scott another, cheaper, higher performance, more reliable option.
Ok, but the cheaper option your suggesting isnt cheaper, and as for being more reliable thats very debatable as well
Just different opinions I guess :)
Garret t2 turbo tubular manifold intercooler and mapped at mpg = 210-250 bhp theres a few done on corsa-c uk
Correct my mate runs WG Motorworks who do the conversions
Also im not sure about the X18XE but i know on the Z18XE that you can fit a Corsa VXR Manifold and Turbo if you make the stud holes slightly bigger but the Turbo would foul the Oil Filter and even with a remote filter take off you will need to space the manifold away from the head
As said you need to speak to warren g. Corsasport, Corsa-c or Mig. Good prices for drive in- drive out if he offers some warrenty.
I think if you were up for the job yourself, you wouldnt have asked..?
Stick with the standard exhaust mani and grab an M45 or M62 Blower off a VX220.
Cheap mig'ed mount and some silicone hoses and your away.
yeah they all left the factory with those fitted lol
I know SC'ing the VX is popular but its far far far far from cheap to do to a non Z22 base engine.
Scott, I'd stick with stock compression ratio, get a T25 and decent exhaust manifold, Get a Microsquirt system (or use your DTA ;) ) get a Jenvey Plenum and inlet manifold for your TB's and away you go :) Oh add in the fmic lol
I didnt say they did :p
Other than mounting and installing a drive to the charger unit. SC'ing is no more costly than a turbo. arguably maybe cheaper due to not needing a new exhaust manifold (for moderate power increases at least)
Lee303 built a SC'ed X18XE1 and that really put up good numbers
What I meant was since no VX left the factory with a charger, the ones that do have them are 'modded' so the only chance of getting one off is if someone nails the car into a tree or upgrades to the Harrop to get away from the hEaton lol. It would be cheaper to get one from the USA but even then the unit alone is about a grand + ancillaries, supercharging isnt necessarily the cheaper option to be fair.
ah, my error and i stand corrected :thumb:
But I stand by my point that supercharging can be just as easy and cheap as turbocharging.

thats some nasty looking manifold... it must play havoc with the flow..
i was looking at just where would you fit a coopercharger on a nova.... and it would need some amazing work to fit tidily into an engine bay.. maybe by removing the alternator & fitting something clever (see PPC mag article on supercharged xflow with jap alternator fitted onto the eaton output shaft) but the rad side of the engine would be trouble unless you custom fit an exhaust to clear it....
TBH Dave i asked as Ive looked and google comes back with stuff on vectra forums and expensive shizz to regal etc, so i was seeing if any one had any info or ideas of how it can be done "cheapish" before i start looking for an engine etc.
As if the 1.6xe can be done easier and cheaper I'll probably go that way.
And on this one i WANT to try do everything my self!
Yeah scott, as said - i dont think he'd mind just supplying parts and advice. Worth dropping him a pm.
Dont know if youve seen this or helps much but heres a thread he posted up on aoc

This Australian smallblock 1800 turbo was posted on MIG a few years ago, Plenum looks quality. Over 300bhp iirc.

Btw I reckon you should go for it, an engine project (aside from a car) is a neat way to learn about engine building. Get a stand & a donor lump, crack on!
I cant recomend the book 'Maximum Boost' by Corky Bell enough, to explain things in detail & give you ideas.
I think its pointless tbh because by the time you put on a manifold/turbo/intercooler and big block box (cos f13/f15 can't take extra torque) it'll be about the same a 2.0 weight wise
