G200w into Chevette

[Jute]

The engine in the chevette is about to puck out anytime soon.

I can get my hands on G200w with box and want to know how easy it is to put in. I dont have a very big garage anymore so I really want to do a quick conversion.. I.e, 2-3 weekends.

Apart from wiring whats the go? Ive been looking around for an hour now and cant find exactly the info I want in the same place.

- I believe the engine is a straight bolt in to the std chevette?
- I know you have to do custom exh mani
- I guess a new hole in floor for shifter and a new driveshaft.
- Is it cable or hydraulic clutch? Does this hook up ok?
- Speedo linkages fit straight up?
- What radiator is a comman one to use/fit
- Any hiden issues apart from that G200w parts are hard to find.

I know some of ya have done it so would love to hear from ya.

-gemi front swaybar
-custom gearbox x member
-gemini exhaust mani either new exhaust or plumb used gemi exhaust to existing or make new mounts to accomodate a used gem sedan one.
-engine will bolt straight in
-may have clearance issues with brake booster/master cyl (inlet mani is very close!)
-if you can track down a gem sedan diff you can just use the gem driveshaft.
-if you find the diff you may as well find a gem front end so you have a matched set of brakes...not sure if youy'd need to change master cyl too... i get different answers all round on that one!
-cable clutch...still have confusion on whether gem one will hook straight up...
-gem speedo linkage set up different to vette...pretty sure you could fit a gem accel pedal and cable or alternatively Im pretty sure Repco and parts shops can make up custom cables unless you can mod the vette cable where it attaches to carb...
hidden issues: if you change diff double check mounting of pan hard rod... will prob just need a gem one or a adjustable after market one.
-dont take anything i say as gospel, only been looking at it for last 3 years or so!! have 3 chevettes that need to undergo the change. Mcqunt or slidenyo or whatever he lieks to be called has done it before, I have his old wagon.

Stay in touch, I've really gotta get my butt into gear and do at least 2 of mine in next few months, got a baby due in feb/march and thats gonna kill my carplay time lol

Has anyone done this before? A dude has asked me to help him get a G161z into his Chevette. Do I need anything apart from the engine? He seems to think that it'll slot onto the Chevette engine mounts, alhtough I'm dubious about this.

If anyone has done this, can I get a quick guide?

Cheers.

Theres no reason why it won't slot onto the chevette engine mounts. You use gemini g161 mounts on a g200w to get it in to a chevette, Id say the motor would sit fine as far as forward/back goes also. You'll need to make a new gb xmember and the gemini drive shaft may work, but I think you'd need to change the universal to a chevette one.
And, he would need to run an extra fuel line if he wanted to use the standard carb as chevettes don't have returns. Thats all I can think of

Oh, I was so worried about explaining it right I forgot the most important part. Bro, if your putting a g161 in ATLEAST get a g200 or something. Why do something and get it ok, if you can do almost the same thing, and get it way better.

Yeah, I was just saying G161 for the hell of it. I have no idea what engine the dude is using. Sounds like nothing too hard then. I might go out and have a look.

Hiya, yea Im trying to get the g161z into my chevette wagon. The engine mounts were all sweet and it dropped right in. The gemini 5spd was about twice the length of the chevette 4spd and in turn the driveshaft was completely different ay (both in length and in number of splines).
Also I found that the g161z diddnt agree with the chevette swaybar - the sump sits on top of it

I decided to go for this swap cuz it looked like it would be a cheap enough option over the already tired 1256cc I managed to pick up a 85 gem with a 5spd and 84000ks on the clock which had had a priddy major prang - only set me back $120 for the complete car

However after buying the gem I went to australia with the whanau for two weeks and when I came back, my flatmates had got us evicted!
So I had about 12hours to get the gem off the property :/ luckilly we'd already pulled the engine+gbox out, but the diff, driveshaft, brakes, swaybar etc went to pickapart with the car as I didnt have anywhere to store it

lol chevini

Gemini mounts will get the motor sitting in there, I'm not sure about gearbox xmember tho. You can get your driveshaft altered and balanced usually for around $120. Not too expensive.

You'll also have to cut another hole further up your trans tunnel for the selector to come through. And unless you are going to be running a different carb you will need to run a fuel return line cos gemis have 2 fuel lines aye.

I was looking at selling my whole carbi turbo setup maybe its got a Webber and modded manifold. I have a few Webbers but you would need to give em a clean up ect been sitting a while. You just chuck the Webber on the standard manifold with an adapter plate and get some brackets made up for the throttle cable and stuff.

Rofl's , Chevini, similar theme to it as SHEMALE hahah

Why bother with the Chevette diff (say you have a chevette & gemini dshaft, so I assume thats what your moaning about) , the Gemini bolts straight in ,and will be correct gearing for the 1600 motor, as well as being a stronger diff..

BTW, anyone know why in the hell the Gemini shifter is soo far up the transtunnel, did they come out with Bench seats or something, something that neccesitated having them that far forward??

My carbi turbo setup I dunno its a real small turbo which is damaged Has a chip in the compressor wheel still makes boost fine was running like that for about 3 months like that. It has everything to make it run pump,regulator,carbi,all the plumbing,intercooler,turbo and manifold,stainless 2" mandrel exhaust system up to the muffler (you will need to weld one in)all the water and oil lines. Dunno what its worth really its a bit rough in places lol. I might try and find another undamaged turbo before I sell it. Obviously forum members have first dibs and will be abit cheaper to them also

I might not even sell it I might put it in the TE and try and sell it that way might get more that way. It cost me about $300 without the turbo and then there's the time ect . So I spose between $500 to $700. I can help you out with a Webber if you want got heap's.

I know what you mean about the offer thing you always want a mean deal but don't want to sound cheap

the chevette cable is reel close 2 the attachmenty pointy bit on my weber, was st gana xpand the hole a lil bit wit a dremel... they both like a circle wit 2 flat sides jus the weber 1 is slitely larger than the chevette 1...if that makes sense...

[cul8r]

From memory when I swapped the gemini diff into the Chevette I had, the handbrake cable "bolted straight up"

Re: the brakes, if you can find an early Gemini, they run remote reseviour
with a little fiddling an xa falcon booster which is slightly smaller than a gemini item, will fit allegedly

-Fit Gemini sway bar to Chevette
-Bolt Gemini (G161Z) engine mounts to G200W
-Need custom ex.man. to clear Gemini mounts
-Clutch is cable and should work ok
-Custom gearbox crossmember, which is a little bit of a major because shuvs have no decent mounting points for this.
-I would recommend Piazza brake master with remote resevoir to clear intake plenum.
-Piazza speedo is electronic so won't work easily (I never got this far but could be an easy fix)
-Radiator. Find something to squeeze in under the rad support panel like I did on the ecotec shuv. I takes a little cutting but not as much as I did on my G200W shuv.
-Shifter comes up in pretty much the right spot in a shuv. Will need a tiny bit of cutting toward the back/handbrake area. I think you could shorten the remote shifter to avoid this cutting though.
-Hidden issue would be horrible electrics. It pretty much gets everyone so either go a/m or get it all working right before you swap it.
-Drive shaft will need an end changed but thats not a big issue.

To sum up its a little bit involved. If you are doing a swap just for the purpose of a better engine it might be better to get just a SOHC injected G200Z. It will solve clearance issues to the brake master, some parts issues and be easier to work with but obviously not as awesome.

[Jute]

Cheers guys thats basically all the info I needed. Only prob it would seem is the speedo conection.
Trying to keep a cheap conversion so really dont want to go AM ECU.

Other options at the mo are a $1 reserve 89 gem engine. Im guessing its a G161 but some clarification on that would be good.
www.trademe.co.nz/Browse/Listing.aspx?id=189003238
Is a really good option cause it would make for a dirt cheap conversion if I can get it for $1!!! and its local!

A whole Piazza wih low k's nearby which is currently at a pretty low price and means I get brake upgrade at same time. It is G200 however rather than g200w. So I guess this would mean similar problems with speedo and manifold/booster but I only get a SOHC. Also the engine code he gave is LY3?. When I search this I get that it sould be a G200w. He says it is sohc tho so Im unsure, perhaps its had an engine swap at some stage.
www.trademe.co.nz/Browse/Listing.aspx?id=188879017

Or, the g200w which I still like the idea of/I just like the large flat rocker cover, reminds me of the FJ.

[crazytim]

89 gemi would be front wheel drive... sump and gearbox issues would just be the beginning...

[mikuni]

Yeah the Gemi engine is completely different. Its some kind of belt driven 4xe1 or something along those lines. Don't bother with that at the moment, it would be about as hard as my conversion was so you'd be better going Opel I reckon.

Best bet for a straight forward easy conversion is definately the SOHC pizza motor. There shouldn't be clearance issues because the head is much narrower and I think the SOHC piazzas had a anologue speedo drive too.

burntrubber installed an injected one into his Gemini in a weekend and had no issues. The only trouble you would have is the gearbox xmember and the driveshaft + possibly the radiator if you don't have anything else sorted to go in.

[Jute]

Ahh that would explain why the dizzy is in a weird place. Was trying to figure that out!! Didnt even realise the gbox lol.

Gaz

[Jute]

Ok might keep an eye on that whole Piazza then. Seems like a good as buy at $200. If it goes much closer to $500 tho id rather have the Dohc. Surelly custom extractors not be made to clear the booster? Driveshaft and gbox xmembers are needed on both and Ive done ma ny of them so no probs.
Anyone got g161 mounts and a gem sway bar they wanna part with?

Gaz

[mikuni]

Yeah. That Piazza is so mint it would kind of be a waste to wreck it but who cares.

And I would way rather you go to the effort of having a twincam in the awesome 2 door but I just want you to understand that it is the more involved of the conversions. Its not real difficult by any means, just not as straight forward as a single cam.

Nov 24, 2008 14:46:27 GMT 12 Jute said:

Its on the intake side. Clearance to the resevoir is the problem but if you put in some of those Cortina? mounts then you should be sweet come to think of it. I installed mine after I did the conversion and they fixed a couple of issues. They bolt in.



^ you can kind of see the small clearance between the front of the motor and the rad support panel. In chevettes the radiator sits quite far back so you won't be able to use it. Even with another rad tucked away you still won't be able to use the Piazza fan either so you'll need a new rad and elec fan.

Just a shot of what happens when you don't use a Gem sway bar.


I attempt all this before I knew about forums and learnt all this nuts the very hard way and eventually gave up when I was pretty much done, just because I had lost enthusiasm. Kind of wish I finished but ohwell, the Opel motor is more fun and reliable anyway so meh.

The Isuzu twincam will be super awesome in the 2 door though and will suit it hard. I saw plan up a little more, assemble it and get it running in Piazza/on ground before slamming it in then you only need to deal with GB xmember, D/S and Radiator.

[Jute]

Ahh good nuts Brad. I had seen some pics of that conversion but I think they were differant ones.
By cortina engine mounts im guessing your mean the round ones rather than the oblong ones? If so I got spares of those.
Looks like the intake only just hits, might even be able to suss it out with slight spacing on the engine mount? Or I have a remote booster that I could use... hell, the escort aint ever going to need it at this rate!!

I just rang the guy about the G200w and made an offer of $500, if he accepts Ill get it, obviously. It comes with everything needed to get engine running. Would need gem engine mounts, sway bar, gem diff and driveshaft still.

Make that 8hrs by my self and that was doing a manual conversion aswell!!. I did spend about a day sorting the wiring etc before hand thats why it went so smoothly.

The injected g200z went real well to was fun to drive but you must do the dohc.

[Jute]

He wants $650 for G200w and box. A bit more than Ive got at the mo especially because it will need freight from Chrchr. Im going to bid on the whole G200 Sohc and hopefully get that for cheap. Gives me brake upgrade, ugly wheels, diff perhaps, and a running engine with low K's.
