1.4 SRi engine

[C-S_Cormac]

After busting the engene on my 1.4 flair nova i have sourced a 1.4 SRi nova engine(multec) i intend fitting this to my nova, since i wont be able to use the injection on my nova(without alot of wiring and changing fuel tanks/lines) i was thinking about fitting a 1.2 head, would this be good??? is there anything else i should use?? will my 1.4 carb manifold be ok??

Cheers

the SRi head is much better than the 1200 head anyway so no point changing it

as for switching to carbs - theres more work involved in doing that than simply wiring up the loom for the SRi

[mc_hawkings]

what about using a 1.6 gte head?

[benji]

i thought the sri loom was a bit of a bitch to wire in.?? somthing about it being part of the main wiring loom. although i could be talking bollox

[mikeyredtop]

it is part of the main loom but can be unwound, or cut as i did... just leaving the 2 main wires, red and black,...

[Philsutton]

i thought the 1.4 flairs were single point injection anyway?

i thought the 1.4 flairs were single point injection anyway?

yes they are and have the injection pump and lines, all you might need is the uprated fuel pump off an SRI etc

[C-S_Cormac]

Nope mine is deff early 1991 1.4 carb with the automatic crappy choke!!

The engine i have got to fit is outta a Sri nova, can i just fit the manifold and carb off my busted 1.4 onto the new 1??? I no i will either need to drill out the hole in the rocker box for the fuel pump or get an electric pump but what else would i need,

The sri engine has blown the head gasget so thats why i was wondering if there was a different head i could use that would give me more power!! would a cam outta of another nova eg 1.2 1.3 1.6 be any better???

swap the complete engine. nothing in ur 1.4 carb will be better than the 1400sri.

Need to swap the whole thing.

Give yo 11bhp up from a sr straight away.

[benji]

the sri head is the one to fit for more power, so if you fit the sr head to the sri then you are going backwards

[Will]

Give yo 11bhp up from a sr straight away.

and 22bhp from your 1.4spi ;)

[Euan]

engine may have had a bit of a thrashing if its blown its head gasket?

how much you paying for it?

[mc_hawkings]

There all the same 1.4 blocks regardless of model

[C-S_Cormac]

Im paying 30 quid for the engine, I thought it would be worth that, 2 of my m8s work for vauxhall and reckon the head would b worth 50 quid at least as the valves on the multipoints are expensive!!!

I was also thinking about a webber 32/34 would this be worth it???

is this engine the same as wats found in mk3 astra(Multic??)

If you feel you just want something to drive until you sort out further project plans & dont want the hassle of wiring up looms & injection do it. As for fitting it should be only 2 wires to the coil to get it going junk the single point crap. Fit your 1400 engine & put the 1.2 head on with 1.3 inlet & your weber.

[C-S_Cormac]

Isnt the 1.4MPi have a big valve head??????? surely this would be better than a 1.2, which cam should i use i wonder??

Cormac

[Snowface]

don't know why some of you think he has a spi engine.

Nope mine is deff early 1991 1.4 carb with the automatic crappy choke
Its a 1400 running on carb's the man says!

The reason why the 1200head/1300manifold is a good opton is because its easier to do than get an sri head matching to the inlet ports on his 1400 head.

There would only be 3-6bhp more with the sri head anyways i would think.

[benji]

sri block has different piston's to the other 1400's.

get some t40's on a 1600 manifold and slap them on the sri head. :twisted:

i payed ?40 for my SRi headso ?30 for the whole engine is a bargin

[Snowface]

not if the engines blown/valves poking out of the cam cover! :o

[C-S_Cormac]

The head gasget has gone just, im hoping a gasget will cure it,

Will someone please answer my questios YES or NO

1:- Will my 1.4 (carb) inlet manifold fit the sri head??

2:- will my 1.4(carb) ezaust manifold fit the SRi head??

Many thanks again!!

Cormac

1. No - needs modifying.
2. yes

[C-S_Cormac]

1. No - needs modifying.


What modifying does it need, wat other manifold will fit??

1:- Will my 1.4 (carb) inlet manifold fit the sri head??



1. No - needs modifying.

I thought that apart from the lower end of the port opening, the ports matched. ie if you lined them up then the sri port opening would fit inside the shape of the sr, just with the extra bit at the bottom. if so, then yes they'll fit together and although it may affect flow, I would have thought it would be minimal, and the slight disruption in flow would aid the mixture, which is always good.

EDIT: I was thinking of the 1.3sr not 1.4

[Snowface]

i stand corrected.

[_JH_]

maybe not snowface. i'm not certain, the sri port may be wider. someone with the two items handy should confirm it either way

[C-S_Cormac]

So will a 1.3sr Manifold suit then?? if not im just gonna stick a 1.2 head on her, feck it IoI

Cormac

EDIT: I was thinking of the 1.3sr not 1.4

ah you may be right about the sri fitting the 1300 easier but i thought the 1400 head in quiestion (with the square ports) needs modifying to fit the sri manifold.

Benji has had to do it to his 1400 head so fit the sri manifold.

and in answer to the 1300manifold question.

use the 1300 manifold on a 1200 or 1300 head. a 1300 manifold won't fit your 1400 head..... (i'm pretty sure of this, derek? :? )

[C-S_Cormac]

Got the engine last nite there, dry as a bone no oil leaks which is a plus!!!

The SRI has round ports, so does the 1.3 sr manifold??? they should fit??

Cormac

[Aragorn]

the 1300 ports are a bit wider at the bottom than the sri ones

it should be alright for the time being although a set of 40's and 1600 manifold would work a treat
