does any one out there no if a gsi head or a gte head etc fit a 1.4SR and if i does will i get much more BHP than having a normal 1.4SR car??? and how costley and is it a major job if it can be done???
:roll:

gsi / gte dont have a carb
im sure it would seriously drop the compression ratio aswell!!!

too greatly as well
detonation issues will exist i would have thought

i've got a gte head, vlaves and cam on my 1.4sr, hasn't made much difference at all, hopefully just strengthed it a bit.

you only get detonation issues when increasing cr not reducing mike ;)
ive seen a couple of rally cars with gte head on but i dont know what else they have done to get cr etc right

my mates JUST done exactly the same
so we dropped it straight out and whacked a cav SRi 2ltr 8v in :twisted:
great excuse we thought!

how hard are engine transplants? my dad changed the whole head, includein tacking the old one off and new head gasketin just over 2 hours, so take that in mind, how long would it take him to change an engine?
i can get a 2.0 8v sri engine no probs.

I'd go with the SRi head if i were you, it raises the compression a tad, plus it flows much better.
I wouldnt bother with the 2.0 8v if I were you -its OK but you can do much better. You get a lot of extra weight for not much power really.
You can either tune your 1.4 - quite lively if you get an SRi head on and upgrade your carb etc
or
transplant in a 1.6 and spend some money on tuning the head - maybe going for 40's etc.
Both these have light engines well matched to the cars handling
or
If you want big horsepower and dont mind too much if the handling is not quite as good, put a 2.0l 16V in. This requires some fairly major mods but it is a common enough transplant so you'll be able to get plenty of help and advice

note to benjoyce:
the engine should actually be a good bit quicker now but since uve just bolted the head on uve lowered the compression to around 8.8:1
this is really too low for a NA car, infact im sure a lot of turbo engines including the LET are around this level
what u really need to do is get the head skimmed (by about 15 thou if my calcs are correct) to bring the compressoin back up to 9.5-10:1
CP:
any news on that head yet??
I had a 1600gte head and injection on a 1400 and it ran perfect. head was skimmed once that i knew of.

how much differance did you get out of it top end???
how much hastre is it too all fit on??? and what do i need to buy too do it all???
to be honest it was grand power wise but not really worth breaking a 1.6 engine to do unless you have it to spare.
you need to fit the 1600 pump and join in the engine wiring to the loom in your engine bay. If its a 1L car then you will need to change the tank too.
I was using a GTE and basically changed the block.
Put in a 1600 GTE or GSi unless you really can't insure it.
1.6 is stamped on the head so you would be as well to put the 1.6 bottom end in too!! :|

brian - im not saying it WONT run
just the GTE head and injection will flow soo much better than the original you should get a nice improvement over standard
however the drop to 8.8:1 compression will lower the power a good bit - from the nice improvement
so your prolly gonna be getting standard power levels instead of SRI+ levels
1.4SR_RED_ROCKET:
you need: 1600 or SRi head, GTE inlet manifold, GTE loom and ECU
and thats it
the SRi head will make it faster than an SRi since the SR has no cat to slow things down
the GTE head will give about standard power from what ive heard in this post unless u skim it down
however the drop to 8.8:1 compression will lower the power a good bit - from the nice improvement
so your prolly gonna be getting standard power levels instead of SRI+ levels
i agree with that, thats why i was saying its not really worth doing

well that all depends
i CBA with carb icing in cold waether and its permenantly cold up here
some will say the induction roar off a injection engine is nicer too
its all personal prefrence
the head will need skimmed anyway before u fit it so u may as well get the machine shop to take the 15 thou off to get the comression right back up wont cost that much more if any

it took me bout hour 2 put me 1.6i in, then couple of hours for everything else.
if u tune the GTE/GSI up they can be very quick, mine outdid me m8's cav SRI, he did have 4 in the car though :wink:
i think either 1.6 and strip it totally, make it as light as poss and it will be V quick!!!
me m8 did that in his 1.4 mk2 fiesta sport, it out did a 2.ltr calibra off the lights, but it has only got 2 steats and a dash :D :wink:
want 2 take mine up the pod soon, but want 2 strip it, take passenger seat out, speakers, put a old set of 15's on 2 , running 17's at mo
be fun 2 see wot it can do :)
for SERIOUS POWER just put a valver in!!!! :D :o :wink:
