Smoking scoobies, and 1.2 in the same sentence??? Fit a 280bhp LET engine, then convert it to 4wd.

Other then that youll be relegated to catching up Saxo furios or maybe the odd mondeo :thumb:

[Stuart]

hmmmmm i hope this is a piss take thread for a first post....


tbh if you want to have a pop at a scoobie, id a) nitrous the living daylights out of the 1200, and b) only race 1.6 imprezzas...

[Mike]

a) nitrous the living daylights out of the 1200, and b) only race 1.6 imprezzas...

Lmfao! How much N2O do you think a 1.2 would take before detonation? About 50bhp max?? :wtf:

well seeing as it shares the same block as the 1.6 and 1.8 i would say its no different from what they can handle

im not really in to destroying these rare cars to fit LET's and 4x4 converisons. i want it to be a real sleeper

[meritlover]

so can any one suggest any REAL tuning mods, or does this site specialise in engine conversions and N2O kits?

[burgo]

well seeing as it shares the same block as the 1.6 and 1.8 i would say its no different from what they can handleerrrrm which 1.8 is that then???

[meritlover]

whats the difference other than an over bore?

[burgo]

1.2-1.6 have a smaller block the 1.8 and above so no its not a case of an over bore

[meritlover]

but what differences are there between them?

[burgo]

1.2-1.6 have a smaller block as in smaller

[Nick]

stu is building a reletivly insane spec 1200 !

but lets face it, your NEVER going to make it quick, in terms of big Turbo Cars, by N/A tuning.

[meritlover]

i have a 993cc 12V 3cyl turbo GTti its small engined, so is it a waste of time trying to get more than 170hp ATF out it?

[meritlover]

1.2-1.6 have a smaller block as in smaller
smaler as in? bore size or is there any difference in the crank journal diameter and the stroke?
is it smaller between chassis leg engine mount to g/box or is it just 'smaller'?

[burgo]

the actual width of the block its self and possibly the height aswell

[meritlover]

width or length? is the increased height due to an increased stroke/swept volume increase?

[meritlover]

what are yor feelings on these eBay superchargers that guarantee 20hp increase in any engine. thats quite a claim is it not?

[burgo]

width or length? is the increased height due to an increased stroke/swept volume increase?width as in the bores are further apart from each other and yes i beleave they are slightly taller for increased stroke

[burgo]

what are yor feelings on these eBay superchargers that guarantee 20hp increase in any engine. thats quite a claim is it not?they are bull****!!

[meritlover]

so forced induction is not the way to go?

[meritlover]

width as in the bores are further apart from each other and yes i beleave they are slightly taller for increased stroke
so they have a different crank? it must therefore be longer to account for the centers of the bores being further apart

[meritlover]

if i was turbo charging my carb would i use a draw thru or blow thru set up? to get the best off boost performance?
or should i use a MPI and 1.6 head with a Wolf3D ECU and external MAP sensor and larger injectors. obviously id have to block the EGR valve off and fit a lower compression head gasket (copper or simelar) and fit forged pistons. what will the std rods take power wise before they exit the block through the side?

READ what i wrote.

I said "with N/A Tuning"

if you want serious power, forget "blow through", you'l have to do it properly.

[Nick]

IIRC the standard rods in a 1600 are good for 300HP, unforunatly i don't think there are a widely available forged set for the <1600 engines.

[meritlover]

are they not compatible then? are the gugeon pin and big end journal sizes different?

sorry my english is not good

[Nick]

are what, not compatible !?

i presume your meaning using a Forged Set from another vauxhall engine ?

Have the Rods Shotpeened and Deseamed, and they should be fine for any realistic amount of power that your going to beable to get from a 1200 !

[meritlover]

the rods iam the one who is talking about the rods.
i was going to have them nitrided. to toughen them.

i was going to source some pistons from a daihatsu diesel van and skim the crown so they do not interfere with the head

thats about the most sensible post youve made so far.....



what exactly do you want to do? go "fast" but keep a 1.2 engine for alleged cheaper insurance... OR just be different, OR tune it while you wait to fit a bigger more powerful engine from the off...

as for "i dont belive in destroying rare cars" they are only cavaliers and calibras. nothing special.

[wisewood]

i think he means he doesnt want to rip a nova to pieces and make it 4 wheel drive etc Stu... thus destroying his rare car.

If

[wisewood]

If you read his posts properly you will see his point quite clearly lol.

[richi]

about the 20bhp chip things on ebay all they are is a resister, had one on my corsa and didnt do anythig apart from putting more petrol into the car. After all the dicking about ur doing to your 1.2 is it not easier to just drop a 2ltr redtop an just tune that?

[wisewood]

richi, people come back with this arguement all the time - easier is not always what people want. Achieving great things from something smaller can be more rewarding than achieving mediocrity with something bigger.

190bhp 2.0 16v nova = quick, but nothing worth shouting about in terms of achievment.

140+ bhp 1.2 and suddenly you have achieved something.

Best qoute ever to be used in the next small block v's big block argument! :thumb: lol

Anyway, Nova, rare car??? I think not my friend. Other then that, without an engine conversions or an http://www.mvaux.com kit, your going to be running very low in Horsepower as there really isnt all that much you can do to your 1200

Here Here any one can build a red top nova it takes thinking and hard graft to build a 1.6 @ 160BHP

[richi]

and loads of money, get what your sayng but then for all the money u spunk on a 1.6 with 160bhp you could get the redtop to 230bhp or something mad like that

[Mike]

and loads of money, get what your sayng but then for all the money u spunk on a 1.6 with 160bhp you could get the redtop to 230bhp or something mad like that

But thats to easy for my liking though, and then youve got the whole weigth issue.

I can see this going back to a heated big v's small block again :thumb:

[richi]

yep need to get a poll going

[Nick]

well mine is great ! I love it !

After being in, and driven 2 nova valvers now, i can safely say i prefer mine !

Just the general sound, feel e.t.c

[Stuart]

lmfao do you know how much a 230bhp 2.0 xe would cost?!?!?!? :roll:

[Dar]

yep need to get a poll going

Im sure its been done before and to be honest its a boring subject. Use the search button:thumb:

Correct, youve achieved something, well done. But if i wanted to achieve something i would do a sculpting course and make a giant naked statue of Stu and display it in my garden.

Im still going to go quite considerably quicker in a 190 bhp 2.0 or 1.6 XE than you are in your 140 bhp 1.2.

So the ultimate question DOES come down to what stu said. Do you want it to be quick, or are you doing it to be different? Cos id rather spend the least amount of money for the best possible result if i was going for performance, its just common sense!

[Stuart]

ditto ;) id have a TB'd 20xe at the drop of a hat, but thats not the point

[kronk10]

people always say this but its what the people who are driving it want. Thats why iam spending alot of money tuning my 1.4 cus its bonkers and different. But i do see peoples point i caould have put a really nice xe or let in there

[stv-b16a]

the weight issue?

does any body know how much more a let weighs than a small block 8valver?

[Welsh Dan]

An XE is supposedly around 40kg heavier than a small block 8v. If you're fitting an LET then the weight isnt as much of an issue as handling the power ;)

[Ash]

1.2-1.6 have a smaller block the 1.8 and above so no its not a case of an over bore

ahh, the x18xe (?) corsa c 1.8 sri engine is a small block - i remember some greek guy used the rods from one for his 1.6. i think it was a tirga turbo conversion.

Ash

[stv-b16a]

when you say small block do you mean the same block as the corsa A or nova.

[Stuart]

FFS not another bunch of girls whinging about the big v small lol.


yes a small block is the 1.2-1.6 in the corsa A/Nova (same car), and the 1.2-1.8 in the corsa B/C's. They are in others too but meh.

big block ranged 1.6-2.2

[stv-b16a]

what are the 1.8 units like?
anyone on here fitted one to a nova. isit 16v. same as my 1600 16v out of a corsa b sport?
