Astra 8v GTE into nova SXi

[djshaggeh]

Looked at the astra gte earlier.
Its been stood for 2yrs on the drive due to the owner having a heart condition and not being able to drive.

turns out its an 8v lump (C20NE or sommat)
got digidash
white gte alloys
113k on the clock
windows work (just due to the moss)
rust on the arches (one side looks mint other side looks like a shed)
wear on the seat
no rust on the underside

Offered matey ?100

Im going to pick it up tommorow :D

I currently own a k plate SXi Nova.
Lowered on apex spring n shox.
SR interior
No backseats
GTE alloys

I want to pull the 1.2i lump out and add the 2.0l 8v.

Anyone have any information/ guides /links?

I have read the guide on topbuzz and it seems to be more for fitting a 16ver.

Many thanks
Shaggeh

P.S will post some pics when i have bought the astra

ITs the same as fitting a 16v, as its a big block engine.
So anything you need to do to fit a 16v, you do the same for a 2L 8v.

Infact you can get away with fitting the 8v (20ne/20SEH) with out having to use big block running gear...

Get urself a GTE/GSI flywheel lighten and balence it, added with a clutch for the same or a 1.5td one which i have.. only thing left to do is to grind a bit of the block to allow the gear selector to move freely.. The bit u grind ull never notice.. Bash the chassie leg slightly to allow the alternator to fit.. I have a 2L8v 4 branch manifold fitted to the nova system, bit off welding is required to match it up tho..

As mine is running on a carb didnt need the fuel return...

If ur using the injection then wire her up and jobs a gooden, cheap conversion..

As its the 8v model im assuming that it doesnt have the BIG 16v brake calipers on there?

If there not 16v brakes can i still use them for me nova?

Drove the astra home earlier. Put a smile on my face :evil: handles really nice. Not the quickest motor ive drivin as i also a lancia delta hf turbo :wink:

btw a quick tip for anyone wanting to buy a gsi, dont buy a delta hf turbo
cheaper to insure, cheaper to buy (more expensive to run) BUT loads more fun! My insurence company wouldnt insure me on a insurence group 9 gsi but they would insure me on a hf turbo (group 14 - 1.6 16v turbo)

Just a few questions with regards to the topbuzz guide: (www.topbuzz.co.uk)



Fuel tank/lines:
If your Nova is carburettor fuelled, then you need to replace ALL the fuel lines and fuel tank and pump to a injection system. This is because the injection system found on the 2L engines run at a higher pressure rating. Hence the old carburettor pipes may blow ! Easiest method is to fit a fuel system from a injection Nova, i.e. GTE, SRi or GSi cars.

will i need to upgrade mine? (k-reg 1.2SXi) im guessin i will. Go for a GSi/GTE setup?


Brakes:
These will need to be upgraded no matter what base model of Nova you have started with. The minimum requirement is to replace the front brakes with the bigger 16v ATE calipers as found on the Astra GTE and Cavalier SRi's (basically any 16v car). The rear brakes don't really need upgrading, but they can if you so wish. Both the GTE and GSi models had bigger brake servos as standard. If your Nova is not a GTE or GSi, then changing the brake servo to the bigger item will benefit the feel and braking power of the bigger brakes.

will i need to purchase 16v brakes as my astra is an 8v model? if so is there anthing i can salvage from my astra?


Engine mounts:
There are ways of using the Nova mounts to install the 2.0 lump, but it can be more hassle than it is worth. There are 3 enigne mounts in a Nova, only 2 or them needs modifiying or changing. First off is the drivers side (off-side) engine mount bracket needs to be lowered by 1.5 inches, then the rear mount need cutting in half and re-welding. This method works but puts the engine too far forward and can complicate other things. The highly recommended option is to fit some specialised mounts (i.e. from CarQuip - ?50), these are modified to give the engine a good position and look better too. Also fit new engine mount rubbers all round if the old ones are worn. The near-side needs no modification and can be alone left as is.

where is the best and idealy the cheapest place to buy the mounts? valvers.com? could i fabricate them myself?


Drive shafts:
Several solutions to this, but any version is expensive. The standard Nova drive shafts won't fit the larger 'big block' inner CV joints. Either modified Nova drive shafts are required or modified CV joints are used. More details on these later.

where is the best and idealy the cheapest place to buy the driveshafts? could i fabricate them myself (my friends dad 'splines' for a living)


Wire loom/ECU:
There isn't much wiring to be done, but it is easier if your start off with a injection model of Nova. The whole original Nova engine, gearbox, wiring and ECU (if fitted) can be removed as a whole from the car. Then when you fit the new engine in, you need its ECU and wiring loom to finish off the job. Basically there are only a few wires to connect

again, mine IS an injection but not a SRi GTE or GSi, so will my 1.2i loom be ok?

:oops: many thanks for reading my late night ramblings any help would be appreciated, pictures coming soon.........
