what power will this give from a 1800 silvertop

its a base spec 130 lump

if i was to fit fast road cams 4-2-1 induction kit and have it mapped what sort of power would i get around 145-150 maybe?

cams will give about 3-5bhp, manifold about 3-5bhp, Induction kit will give 0bhp as it will be sucking in hot air, you'll be lucky to see 140bhp depending how good your engine is to start with

even with it mapped? would of thought with having it mapped i would of gotten more than that. i knew the gains wouldnt be very big without a map.

Custom remap or chip?

from what ive looked into it would be a custom map put onto a chip looking at about 350 -400 for it so was assumin it would be a proper map on a chip. if not i would just wack it on megasquirt and get it mapped that way as i could do that for about 400 all in.

STANDARD ZETEC 130 bhp then you have to take into account the loss of power you would lose of the life of the engine which roughly say 15 bhp so you have about 115bhp then cams depending on profile about 5 bhp filter no bhp manifold would help the engine breath better would give about 8bhp then you have to ge tthe car setup to ge tthe best out of it which depends so roughly 135bhp i only got 145bhp on my 2.0fiesta that was with a stage 2 ported head and raceline cams and 4 branch manifold and chip

Ive got a RS1800 and im having the same problem, i want more power thought of cams, mapped and so on but is it really worth it ? if you want power off a 1800 its got to be throttle boddie kit or turbo.... In my eyes

the way im seeing it as like u say the proper power will only come through modded intake ie turbo or throttle bodies but with my current funds and other things going on at the moment this is what im looking at doing and maybe in the future either whack a turbo on or bike carbs and if i do either of them the cams will still offer me a benefit the only downside would be the 4-2-1 if i turbo it but i can sell it on an get some cah back anyway.

dont waste money on bits for that zetec the only way is putting a 50ish shot of nos in its the cheapest way and if you dont go nuts kind of safe to do

I'm with mikey on that. Cams, headwork etc will only get you very minimal gains.

As I recall, the rs1800 cams are fairly wild anyway but I'm sure others will confirm that.

If you're looking for reasonable to major power increases then you have to look at NOS, alternate high-octane fuels (race fuel) or forced induction - forced induction's been done so many times now and the zetecs make good, reliable power - even from a homebrew setup; it's almost rude not to.

If you are determined to look at significantly higher power output as a long-term aim then I'd invest in megasquirt v3 so you can run fully sequential injection when you go forced - I wouldn't bother with a chip when MS is so little more money.

ive looked at ms theres a bloke local to me who will build it and fit it with a full custom loom and map it with a wideband but wants around 500 all in which ent bad but though if i had 4-2-1 and cams might get me a bit of power when getting it mapped then save for either throttle bodies or a budget turbo conversion.

I had 146bhp (on dynodynamics R/R) on my other halfs escort gti 115ps with piper reprofiled cams, 2ltrT/B, magnex cat back and a superchip the engine had also done 95k. so it is possible to get gains from them if its a good engine to start with.

Great price that. An MS is about, what, 250-280, plus 100 quid for wideband (if using innovate) so really not bad at all. You'd probably get a basemap included, dunno if he's do you a good live map on that money.

TBH though, while you might think it's about the headline figures, in reality going to a custom map will iron out any flat spots you're experiencing in the cars performance and make you ready for a turbo conversion later. It's a win-win situation.
