i've recently bought a 1.6si cvh engine on an m plate.

how can i squeeze the most bhp without droppin a 2ltr in it. earlier i read dat an xr2i 1.6 cvh could get roughly 130bhp, is dat possible for my si?

lets say for now money is no object, so dat i can get everybodys full opinions

cheers

A backbox and air filter is as far as you should go. This engine does not respond well to tuning. The only realistic option with his lump is to rip it out and put a bigger 1800cc or 2000cc unit in its place.

You could throw a couple of thousand and still have next to no improvement in the performance

[black2]

Firstly if its an SI it should'nt have a 1600 CVH in it, should be a 1600 Zetec

Secondly the 1600 zetec does not tune well, here read this :

its on a change over year its mk3 with the upgraded cvh, the mk4 has the zetec.

i understand what you're sayin but i bought the car 3 months after passing my test so i don't wanna go to mad to soon. a 2ltr could reach 150bhp but i'd be happy wit roughly 115-120bhp.

would i benefit from uprated cams, individual throttle bodies, light weight enlarged pistons, 4-2-1 manifold, sports cat. and remapping

Upgraged CVH if its a genuine SI it should have a Zetec, OR a 1400 CVH? SI's are mk3.5's.

Im confused, get some pics of your engine.

oh yeah my mistake, just checked my source again read it properly. it is the mk 3.5 zetec. but still how would those mods that i mentioned earlier still work out

[Jonezy]

u would be luck to get 5bhp i think,

cams cost £300 for zetec
induction£50
full exhaust system inc mani £400+ ( inthink)
remap £150+ (maybe)



trust us just save and get a 2 ltr when you can afford it

im stickin with a 1.3 until i can, you will probably soon be tols by guys here to wait until you have quite a bit of driving experience before goin fo a bigger engine.

[chrisosi]

so is there actually any point in adding an induction kit and backbox?

[Jonezy]

apart from noise



no, but is there ever much point around 100 bhp, very little im sure, not the usual 10% power gain the ads claim

[ste_turbo]

If money was no object then put a 2 litre series 1 mondeo engine in. That will take you near 130 afaik. Then you have more options if you want more power. If you were confident you could do this yourself relatively on the cheap.

i would love a 2ltr engine, but i only turned 17 in april and passed my test in june, so i dont think a 2ltr would be very insurance friendly.

i got my si, after drivin bout in my old (v. old) corsa, bcos it was insurance friendly. i'm just tryin 2 find out what i can do 2 get the most out the current engine.

[fiestamodder123]

to get the most out of a 1600 zetec the best option would be to throw it in a skip because the head design is s**t ,valves are way to small , was designed for economy NOT power

Rip it out and drop in an 2.0l ,insurance only goes up to group 9 with the 2.0l in

[freekstyle]

prob the best post that i have read on here so far... lol i also drive a 16v si (its good fun and im working on the handling rite now but...) im also after a mondeo engine could someone direct me to a post of how to do it? cos im sure there is one. cheers lads

Guides, near the top because it's soooo popular.

Anyway, more power from a 16v Si is easy. Chemical supercharging. Nitrous is the only real way to get any real sort of gain.

[Jonezy]

would a focus 1.6 zetec head fit, this could be better

[freak power]

Its not just the head thats the problem with the 1.6 16v, All Zetec share the same crank witch is a 88mm stroke witch is a lot for a 1.6 and the bore are really small

[Jonezy]

the 1.6 focus is better tho, as they are faster in a heavier focus so surly swapping to this wiould be better than nothing (obviously i agree a 2ltr is better still)

It depends on what year of focus you get the 1.6 from? as the later ones run the same engine as the fiesta Zetec-s

[lucasdemoley]

I'd say throttle bodies and megasquirt. Then when you can insure a 2.0 you can put them on that car, giving a big power increase.

As for 2.0 si being group 9, maybe, but alot of insurance companies wont touch you if you like under 19 with this. I cant insure my 19yr old gf on my car.

[TarmacTerrorist]

if i were u m8 i wud bang the 2.0 litre engine in and keep the car as a 1.6 on the insurance . jst u will get in sjit if ya crash

or change it to a prper engine a CVH turbo

Or how about you put a 2.0l in and declare it on the insurance Only group 9 for a 2.0l afaik? 1.6 is group 8 as it is.

Posts like that piss me off.

Agreed, If it isnt insured right it shouldnt be on the road.

Or you could take that 2.0 and ram it as far up your colon as possible.

I can't believe the amount of people who come on here and give illegal advise, absolute c**ts.

Stick with the 1.6 get some NCB then worry about more power. Your quite lucky you have a 1.6 as a first car. Most of us had to pootle around in a 1.1 for a few years before getting something with a bit more power.

Best thing to do really is get an induction kit for the sporty growl. Anything more than that is not worth it on that particular engine.

A good meticulous service will help a lot too.

Also, in this aspect. The conversion to a 2.0 is much easier, less work involved. And as standard the power isnt greatly different.

[HCS PIMP]

I had a 1.1 for a year spent 1 k on it new 1.1 engine respray cams kit induction back box ekotec ingnet valve ran iridum plugs v power the lot
and it added about 15 bhp max trust me its worth waitin for 1 year then get a 1.8 zetec engine or 2.0

If you really got the money and no sense there is one option no one else has though of

Im currently planning to do up my 1.6 si engine


first get new je pistons and over board the engine to a 1.7 then get a space block made on a cnc machine. The get a 1.8 zetec cyl8inder head and get them to gas flow the head and made it fit a 1.7 will probs cost about 2 k for all that

Then get new manifolds both intake and exhaust then grab and nice t25 - 34 garate ballk bearing 360 degree turbo

The new plus new leads new injectors and new ecu

Add some nice oil cooling and castol edge oil

Try some 30 shot NOS youll need to have up new conrods and crank shaft if you want the nos fitted

With tunning done at the cams shafts and ecu poss new cams and vanner pullies you could be runnin 250 bhp from a 1.6

yess insane and need all new suspension and brakes but think of the noise the engine would make and the noise the bank manager would

Muhahahahahah

Everyone will probs say this post is gay and insane get a 2.0 with megasquirt but i say its your do do what you like end of the day its a 1.6 yoiu can do 90 mph up a hill thank the car gods you didnt get a 1.1 spent 3 k and then have to buy a bran new si Trust me not worth doing little mod unless you got a 2.0 litre unless you got 3k and the need fot a 1.7 wait and then get a 2.0

or a better car fiesta are great but for the 5k a show car will cost you can have a newer fiesta zetec s

[TarmacTerrorist]

sorry ppl to hear bout ya 1.1 trouble but i must be a luky one wid the xr2i as a first car

n i wasnt reali tryin to give illegal advise i was jst postin another suggestion but i wont do it in the future

[xiphon]

im stickin with a 1.3 until i can, you will probably soon be tols by guys here to wait until you have quite a bit of driving experience before goin fo a bigger engine.

Makes two of us

I've been driving about 5 years now, and only just thinking about changing my 1.3 HCS for a XR2i in the summer

*actually, I lie - I drove a 1.9TDi Seat Cordoba as a named driver from 17-21...

[Jonezy]

abd another, 2ltr next year
