ive heard a lot of people useing these carbs, do they give a bigger power or torque gain?
what would be the benifits of fitting one of these to a 1.4sr?

i have one of these on my sr with a few other engine mods
runs ace when its not too cold, but i have had it ice up a few times with the k&n bolt on filter on.
i have heard on an otherwise standard sr you can get around 90hp with one!

Would benefit a warm air feed in winter time.

i have a gte cam in mine, infact i might as well list most of my modifications:
gte cam, full exhaust system, k&n, uprated plugs, 32/34 weber, 4-1manifold to fit, few other mods, rebuilt head etc
it goes like stink, no official times yet, but i can out accelerate quite a few motors! best was a saxo vts, owner looked wounded!!!! lol
get that carb, then do a few other mods and you will have a rapid motor!

Untill august I was running a standard 1300 with a 32/34 and a piper 285 cam, It was giving 85bhp at 5000rpm which is standard 1.4SRI power.

ive got an sri head ported and polished, 320 degree cam, a full scorpian stainless, gona get a 4-1 manifold and will also rebuild the bottom end new rings, shells and arp bolts. hopefully i will see 100 bhp at a guess.
how much would you say a wber 32/34 cab and sr inlet would cost second hand, what would i expect to pay?

the nova would have been ready today mot etc. but.........
i sold the escort, the punto ran out of tax and we sold that too, my sister banged her car and i scraped it and my old man retired giving his company car back!
so now 5 0f us only have 1 car lol ive been strugleing to get to my garage to do work, realy wanted it out for the weekend. at the mo, its just a standard sr engine with gte sorst. woopee!
this carb im after is on ebay, was on a 1.4 sr with a 1.3 sr head. i dont now what they origonaly come on, prehaps its just a replacement carb for competition use :S
just need to know a decent price as some guy is offering it to me for ?100 :D
i have a gte cam in mine, infact i might as well list most of my modifications:
gte cam, full exhaust system, k&n, uprated plugs, 32/34 weber, 4-1manifold to fit, few other mods, rebuilt head etc
1.4Sr cam is a better cam than the gte one, marginally, but it is.
Luv2xlr8-What inlet are you going be using to fit the sri head?
I'd guess you should get about 95bhp with that spec.

I got 89bhp on very accurate rollers on 3 power runs with a standard 1.4 with a 32/34. Engine had only 7k genuine miles on it at the time. Sounds mental but its been checked 3 times now and it always hits the power.

Yeah i did it DIY style, and it worked, but it didn't last too long and when i recently removed the inlet, the filler i used to mod the port had been gobbled up by the engine lol
If you can find some kind of aluminium putty/filler to use that would be more permanent it should be fine.

chemical metal??
Thats what i used, and i've come to the conclusion it doesn't react to well to constant contact with fuel/air mix,Lol.

lol get it tig'd... my mate at uni is amazing. he worked for hyundai rally team back in the day. offered to weld me up an ally plenum.
If you look tho theres no way of doing it, as you would need about 10mm of weld to fill the bottom of the cathedral port.. which you can't do..
The only way to tig would be cut the inlet in half, tig a small plate in the bottom of the runner, then tig the whole inlet back together,Lol.
I went an engineers on Wed, who specialises in building inlets, gear shafts etc etc for cars and he couldn't mod my t40 cathe inlet to round ports...
Its easy to make the port a bigger shape, but not the other way round,Lol.

so your saying the 1.3 inlet pots are bigger than the ports on an sri, or different shape?
would it be possable to tig the ports from an sri inlet to the 1.3 sr inlet?
The ports themselves are bigger where they meet the head and a different shape.
The reason for using a SE head is it has much larger valves, and the round ports flow well.
" would it be possable to tig the ports from an sri inlet to the 1.3 sr inlet?"
Hmm, i'd probably doubt it.
You would be best looking for something to fill the ports with, like chemical metal, but stronger and more resistant to petrol.
Something like what pro's use to fill marks on alloy rims when refurbing them.
