View Full Version : 1.3 SR -> 1.0 ECOTEC Conversion
Hi all,
I currently have purchased a 1.3 SR rolling shell rally car and I am looking to compete in a 1000cc rally class. They allow you to put smaller engines in to higher spec cars. So i am looking to put a Corsa 1.0 ECOTEC engine and box in to the nova, how hard is this? I know i will need the loom and ecu, but what about the rest eg , cat convertor etc? will the engine need extra engine mounts welding in or does it use the same as the old one?
Any help would be great!!
Cheers
Rick :confused:;)
the old ohv 1.0 engine would be an easy fit, but the 12v 3 pot will be harder even though the gearbox end mounts are the same. the front engine mount would need modifying. the wiring would be fairly complex as there is probably the whole key immobiliser thing which is an integral part of the efi loom.
the power in std form would be fairly rubbish, for the 3pot, and the old engine would probably be quicker.
as for tuning, the 3 pot doesn't really have much going for it, but the old engine would respond to head work & a cam regrind. + a skim to raise compression.
Thanks for the reply, by old engine do you mean a corsa 1.0 L non ecotech?

No he means the old OHV 1.0 Nova engine.

Thing is Shaun is running Red Bull which gives him wings lol
but surely the uber weight of the 1.0 8v lump would sack off any "power" gain over the ecotec item..
a very good point, the ohv weighs the same as an xe.... iirc. id go for the 1.0 3cyl.
can you not destroke a 1.2/1.4 16v ?
Thanks very much for the replys.
The cars engine needs to be stock for the class I will be entering but i can change the brakes and suspension etc. I have gte brakes and uprated suspension and the car is fully seam welded. The other cars are mainly micras (nice!) 1.0l 54 bhp
The way I am currently looking at it is
Nova 1.0 L 45 bhp
Corsa 1.0 12v 54bhp
Plus the nova is lighter than a corsa.
What you think?

has it got to be the same brand engine? if not try charade gtti engine? how about bike engines? they're under 1000cc
Yes i am afrid so corsa is as much as i can budge
id go for bike carbs off a triumph triple and megasquirt mate.
lol, I can't mod the engine it as to be either a nova 1.0 or corsa 1.0?
What do you recon?
put the corsa engine into the nova.
I was thinking that, more power hey! I would have to get the full loom & ecu also, just the bit about the drivers key, can you get round it?
Ive got a 12volt Corsa, TBH, they never gonna set the world on fire with there lack of speed, but nippy little engines TBH.
The T/B is uber teeny tiny and pathetic mind lol

eh?
Should be a bit quicker for the nova then as mine is quite light and stripped out! need to beat the 1.0 L micras!! lol
ahhh, why didn't you say! lol
;-) are you running the engine in a nova or corsa?
i know people that take the corsa key and strap it under the dash then the chip is always there then you just wire the ecu and loom in as you do any other converstion. i also seen people strip the key and put the chip in a alarm fob then it is always on you key
ahhh, why didn't you say! lol

In a Corsa van chap.

Why would you need do that with the 12volt engine? The key is a non transponder unit?!
someone was asking how you wuold get round it if it was i was just answering the qustion

Not in this thread they were'nt :confused: your carping on about an X16 Conversion though chap as thats whats done with them :thumb:
to be honest, you will be struggeling to beat the 1.0 micras... Very impressive cares for what they are

there is probably i was just telling him how thay get round it if there is! only trying to help

lol the engine mount is bigger then the entire engine on the 1L 12v lol
Thanks for all the replies.
So just to check I would need to get a 1.0 L ecotech engine and the wiring loom and ecu. Not the key?
you need the key and transducer and its wires.
you need the key and transducer and its wires.
No you dont. There not a transducer key chap. Theres no immobiliser on the 1.0's.
yes there is on the corsa, chip in key with reciever around ignition barrel
you need engine, ecu, loom, andthe loom for the immobiliser and the key or just the chip from the key. the key is coded to the engine ecu.the car wont start until the code is recieved from the key and recognised by the engine ecu

No there is not.
Mine in all its life has never ever had a chipped key nor immobiliser. Neither did Ste's IIRC.
No immobiliser as nobody would want to nick one? lol

Hmm, I'd put my money on the Nova being lighter if you went nuts stripping it out - the Micra is just shy of a ton, so a std poverty spec nova has 150kg advantage already. The 12v engine can't be THAT heavy... can it?

no imob on 1.0l corsa,s im afraid

Well the Nova has been stripped out it does not even has a dash! The heater has been took out too! I recon its pretty light! be good to beat the micras lol! Its an ex-rally car the guy stripped it and put all the stuff in another nova as it already had a rear disk conversion.
About the Key guys, am going to get a full corsa, I have found a cat c T reg 1.0 12v ecotech with 70k on it and the engine is mint, the guy wants £260 for it.
Just need to find / borrow an engine hoist now!
Pretty certain i've seen Dblias or Mantzel inlets for the 12volt 1.0s claiming a 20ish bhp increase
Yeah you can get a Dbilas inlet for the 1.0s claims something like 18 bhp increase, but its around 1k :eek: .
Only reason I remember that is I thought "imagine a 1.0 Corsa with 75 bhp"!!??!!!!! :wtf:
No you dont. There not a transducer key chap. Theres no immobiliser on the 1.0's.
care to explain why my friends has one then? s reg 1.0 ecoturd. base model.:thumb:
im not even going to bother trying to argue about it, spent 10 years working on the cars and every single corsa from 97 on had an immobiliser in the key, that includes 1.0 12v:thumb:
yeah, i completely agree soup, it was done for some regs that came out in 97 iirc
Every vauxhall from about 1995-96 has a keychip immobiliser on afaik.

My S reg, 1.0 12volt has no immobiliser chap. Which leads me to beilive that no other 12volt does :p

Our Astra Sport doesnt :thumb: N reg aswell?
I will tell you if mine does, lol. My nova is a rolling shell and has no brake servo , from what I have been reading I can use the one from the corsa and stick the servo and brake pedal in?
My mate got 68bhp out of his 1.0 12v after simple mods. Went as well as my 1.2 Nova in comparasion.
lol my mum has a 1.0 12v corsa C , they have chipped keys , unsure what year they started to fit them to the B's but some do some dont
My mate got 68bhp out of his 1.0 12v after simple mods
such as??????????

Maybe it was one of the last ones to do without..
My P reg Astra does :thumb:
As does my dads P reg Corsa

saying that, my mates nova has a x16xe in it, and that dont have one ether :thumb:
engine mount : can anyone tell me the best way to make or get one made for the outside mount. The nearside gear box and the rear mount fit perfect.

My mates V reg 1.0 12v corsa has a chip in the key, only reason i know is i cut up his key blade to put it in a flip key and had to take the chip out and stick it in the flip key.
