Hi all, excellent site well usefull, wouldnt of seen me on here before, not long had me xr2i 1800, looking for some tuning tips, i wanna keep the cost as low as possible and do as much work myself as possible. Ive already got a green cone filter, starchip, powerflow exhaust. What do you reckon i need next? Any help would be much appreciated, cheeers all.

[chumkila]

port and polish/gas flow the head.
cams.

then for serious power:

Throttle Bodies.

[stu1800]

cheers chum. would it be worth throttle bodie first? if so would i be looking at one off a 2 litre zetec mondeo or something else? is it a DIY job?

When he said throttle bodies i think he was referring to the type of one for each cylinder which cost about 1500 quid plus setting up which needs a rolling road, but your looking at 160 break i guess, which is mad. Why not get the cams of the RS 1800, and the larger throttle body of the same engine. I think but im not sure that the same engine was usewd in other model fords so it would make it easier to get the bits from scrappies. What i said may not be exactly right but it worth a shot.

[chumkila]

yea go for moulders option. sorry i shouldve said. thats me getting excited again!

[moulder]

Chumkila out of interest is the RS 1800 miles better than the 2i 16V, as if it's only thew cam and throttle body id be up for a cheap 2i 1 and swapping over the rs parts and getting some other hot goodies.

[stu1800]

so its a RS 1800 throttle bodie im after, how much u rekon this should set me back? scrap yard? is it a difficult job to swap?

[chumkila]

moulder - no its not just that. the RS1800 has oil sprayed into the piston chamber which is diff to the Xr2i 16v. Excursion and Snake are the chaps to tell u the techy breakdown on this.

stu1800 - if u can find an RS1800 one that is, otherwise go for the 2.0 Zetec (i.e. Mondeo) as they are exactly the same.

cams, mapping in the ecu, throttle body, and the rs1800`s have oil spray jets pointing at the underside of the pistons for cooling and increased reliability...

The difference in bhp on the engines is crap, i would say the 2i 16v is around 110-115bhp and the rs1800 is around 120-125bhp

Best engine u can get is the 2 litre and stuff throttle bodies on it, u can get 170-180bhp with a standard engine as proven by Graham and his pukka MK1 fezz. Cams in the 2 litre are pretty wild as they are, its the inlet side of things and the map that restrict the engine. Head flowing is critical on these engines and it really does need to be done by someone who has done a few of these before and have properly bench flowed it.

Well iv just seen a 1.8 zetec out of an escort for sale which i assume is the 2i version with 105 break or whatever it is. I reckon that it will have to be either a tuned up 1800 for me, but if i can afford the insurance a 2 litre would be mad.
