mk2 fiesta turbo with r5 carb
« on: 22:54, Tue 21 August 2007 »
dont no how interested u lot will b with this but thort ild post sum pics of it being that ild b asking a few questions bout the carb n wot i can do to improve it.

all work done by myself, t3 only fitted recently befor that i had a t2 n it just wasnt powerful enuf lol











the carb is mounted on the std xr2 inlet with an adapter i made up n modded throttle linkage. all works quite well n made 140 bhp at 10 psi a few months ago wen it still had the t2 n a small cooler. hoping to get 200 with the current set-up

whooosh

nice car, always had a thing for the mk2 feesty! i had a 1.4s a few years back, quick it was.

i see you have an rs1600i rocker cover on her, standard escort/fiesta rs turbos came with 120 or was it 130bhp so what else is done to her?

you can get a group A carb with bigger jets etc,they work pretty good and better if your upping the boost, alloy carb tops are a good one too, dont think there is anything else to do on the carb front
IF IN DOUBT FLAT OUT!

love the festa, i had one that shape for my 1st car and if it werent for renny 5's and the fact they are so easy to break into id still have it, was only a 1.1 but loved it still, didnt look no where near as nice as yours, id got the xr body kit on it, i got broke into 3 times so it had to go.
looks like your doing some good work there, have you done a quater mile?? what was your time like?

keep up the good work  :D

For 200bhp you will need to re-jet the carb mate, if you can aford it ,get a proper wideband controller, you have a lambda sensor that you have to get the boss welded in for ,but thats the hardest part, then you can tell if you are rich or lean, for 200bhp you will need to see solid 12's on the meter on WOT & make sure it doesn't lean out towards the top end from emptying the carb ;)   you may also need a bigger pump depending on what you have now.

thanks for the comments, the original conversion was using the std xr2 engine n a smaller turbo n cooler but still made 140 on the rr, the main reason for the bigger turbo n cooler was i foung a cheap rst bottem end which had 10,000 on it which was bored to 1640 n contained low comp forged pistons n was all balenced so i thort it wud b a shame to waste a gud engine with a small turbo. currently im waiting on a -31 actuator s mine wnt hold above 5 psi at the mo, gonna run 15 till i get a lsd gearbox. wen pay day comes next week im gona purchase a proper wide band afr meter n do the setting up myself.

GTTBoy- ive been told to aim for 11.8 afr by the last bloke to set the car up. in terms of fuel pump wot kinda up-rated pumps do u lot run? im using a rs injection pump on mine but it dosnt have a proper feed n i dont realy want to fit a swirl pot n every thing. am i rite in sayin that r5 pumps r suck pumps n mount them under the bonnet type thing? is this the same with the uprated ones?

cheers

11.8/12 there's not alot in it  :lol:

Just get hold of an UPRATED GTT pump, there's one on ebay at the moment, they're good for 200bhp ;)
Don't know what you mean about suck. lol.
Not sure that with a bigger engine that you may empty the carb quicker than on the GTT, it normally happens over 23 psi on the GTT but that normally equates to well over 200bhp, you have a bigger engine & turbo so it's all different to mine.

suck :lol:  there 2 differant types of pump, suck pumps which 'suck' the petrol from the pump n r usualy mounted under the bonnet the 'push' pumps as most injection pumps r thet r mounted in or just outside of the tank that push petrol to the engine bay.

thanks for this help.

the gtt has a push pump.

the pump sold as 'uprated' for the gtt is from the phase 1gtt,or you can get 1 from a bmw 318I
