Make my 1.2 faster

[modded_nova]

Hi there was just wondering what people's idears would be on making my 1.2 much faster, Thinking of a 1.4 engine or even a 1.6 but how much work would I be looking at?? Dont really want to go into making engine mounts and brackets any suggestions much appreciated?
Cheers

[Adam]

Engine will fit straight in on the 1.2 mounts/brackets.

[stv-b16a]

fit a 16v from a corsa. and then tune it lol

thats what im doing

[stv-b16a]

general baxter on here has nearly finished his i think. have a look at some of his threads.

[modded_nova]

but a 16V from a corsa you would have to make up and play about with brackets wont you! Was picking up a 1.8 8V this week but just found out its injected and gonna need a lot of work in fitting it, changing ecu, wiring loom etc: Any opinions

[stv-b16a]

nope 16v unit fits right in onto standard mounts

[Ash]

a 1.8 8v is a big block, it would require the same amount of work as fitting an XE, stick with small blocks. Whats the engine at the moment? carb or injection?

btw possible (smallblock) engines:

1.4 8v (nova SR - carb)
1.4 8v (nova SRi - injection)
1.6 8v (nova GTE/GSi - injection)
1.4 16v (corsa sport - injection)
1.6 16v (corsa GSi - injection)

Also if you want more power 8v engines are good with carbs and 16v are good with ITB or bike carbs (mmmmmm)

IMO the 1.8 8v is a waste of time, the 1.6s fit with no issues. With all the extra hassle of fitting a 1.8 just to gain a max of 7bhp (over the 1.6 16v), when you could fit an XE 2.0 16v with the same amount of work but gain 50bhp (over the GTE 1.6 8v)

[richi]

i have the 1.2 injection and wondering how much hassle it would be to drop a 1.4 into it, what would i have to change?

[dannyb]

Drop a 1.4 SRi lump in Richi and it will fit on the mounts and you can just plug the ECU bits stright in. You could also drop a 1.6 GSi lump in no worries, but you'd be subject to higher road tax etc.

[Adam]

/\
The ecu wont "plug" in.
It will have to be wired into his car loom.
1.4SPI will plug straight in :)

[modded_nova]

Mine is on carb, so would a 1.6 8V or 1.6 16V hav small mounts and I dont really want an injection engine because I dont fancy changing all the loom and ecu and that?????

[modded_nova]

Something is really bugging me! Say for example I brought a 1.2i nova would it be less work putting a 2ltr 16V then it would be in a 1.2 carb nova? I know it would still be a lot of work but surly you wont have to change all the loom if its already injected?? help please..
Cheers

[Ash]

yea, you would have to change the looms in both cases, but you would need an injection fuel tank as it contains a fuel pump and/or a swirl pot.

Your best bet is an 1.3 or 1.4 SR engine or a 1.6 GTE/GSi engine converted to carbs (T40's ideally)

Ash

[modded_nova]

Yeah but if I was to get a GTE or GSI the loom is still gonna have to change aint it?

[stafford]

astra do a 1.6 carb if u want a 1.6 easy to change carbed engines
:thumb:

[modded_nova]

Whats to major difference between carb and unjection then I dont really understand! All i know is injection is faster because its injected or somthing!!! confused....

[macc nova]

no mate, carb is faster

[Stuart]

^^^ lmao on what grounds?

the 1.6 carbed engine is a sack of turd (and in may cases is the big block variant)

As for fuel injection info, go to howstuffworks.com and have a read...

learn about what engines do what before making a choice otherwise your simply going to be firing off random questions like you have been and getting nowhere fast.

i know its off topic but thats a really good site, cheers stuart

[Adam]

Injection is superior to a carb(s) in all circumstances.

[Ash]

i hope ur joking lol *trying to think of a positive thing about carbs :confused:*
there cheap (but not to run - petrol)
and ummm....
sound good (so do itb's)
errr... yea lol

A

[Matt2107]

The 1.4SR and 1.3SR carb engines have decent performance IMO.

The 1.3 is probably the better choice but your more likely to find a 1.4

[dannyb]

The carb fed SR lumps are good for what they are,although if I could, I'd have a fuel injected engine SR lump as it is simply more efficient in almost every way.

[Adam]

i hope ur joking
Nope.

Give me a example of where carb is better?

[Ash]

i tried - didnt get very far.

or though it would be better for this guy (modded_nova) as he has a carb engine atm and wants an easy swap. So i that respect carbs are better, just not performance wise, unless its an 8v where carbs are better then itb's but we dont worry about that now - i'll just shut up! lol

Ash

[Ash]

oh, thought of some more:

easier to work on - no ecu
the 1.2 carb is quicker than the 1.2 spi
carbs are easier to tune - don't need it mapping every time you add something - maybe?

A

[Adam]

Injection is easier work on, no need pi** about setting idle speed etc etc.

1.2carb is quicker, yes but not really a fair test seeing as the spi has a much milder cam,a s**t head, and a cat.

Anyways, back on topic :plollol

[Stuart]

say for example you fit ohh a 300deg cam in... you want to adjust your idle fuelling to make it smoooooth.... oh hang on you cant with the spi :p its fixed lol and thats about it..

obv in standard form most EFI systems wont take well to mods, but a quick remap will atleast help

[Adam]

say for example you fit ohh a 300deg cam in... you want to adjust your idle fuelling to make it smoooooth.... oh hang on you cant with the spi :p its fixed lol and thats about it.. The majority of people with a 300deg cam in an engine with carb/carbs cant get it to idle smoothly either :p :thumb:
Most people you hear of with 40s say its a very lumpy idle.

[Stuart]

^^ MYTH ALERT MYTH ALERT
ffs its only the BADLY setup carbs that make it idle rough etc. Jims and dans idle sweet as a nut and havent gone out of tune either :p

badly setup EFI can result in crap idle too lol

[modded_nova]

Cheers for the info still deciding and doing some homework on what's better? Ok What would you do if you was me got a 1.2 and I want to put bigger engine in and make it really fast, How would you make it fast? No time limit in doing it on and what would you consider! Just want some ideas please :D
Cheers Shane

[Stuart]

either a 1600 16V on TB's with a PROPER engine build. OR a 2.0 16V on TB's with a PROPER engine build....

[gaskell63]

why waste ur time easyer just to buy a gsi nova or summat to be honest. and flog your 1.2 unless the shells clean as.

haha just re-read the message meant to say that i prefer carbs.

[modded_nova]

I dont want to but one already done, would rather do all the work myself! I like achieving stuff, its just crap and boring if you brought it all done because you know you didnt build it yourself! Everyones different and suppose i am :D

Wise words from mister gaskell:thumb:

[Stuart]

since any work is likely to be an engine conversion it wont be a 1.2 anymore so gaskells first non abusive post is completely wasted lol
