Ok lads (and ladesses..), here's tonight's tester..

If i've got a grand or so, and want power from the 2.0 Mondy lump, where do I spend it to get the best power returns?

Step 1 is ignore the Zorst/Induction Kit route.

Step 2 is aiming for 200bhp...but not just whilst the Nitro bottle is full

Step 3 is a Turbo-free zone. Getting sick of far too many coolers/radiators up front constantly trying to get rid of too much heat

Step 4 is sod the emmissions factor, so twin DCOE's is well on the cards..

So it's a Cams/Heads/Carbs/Throttle Bodies vs. Cost competition...

[Stoned]

How about a superchager then?

[zetec_si]

You'll need to do all of those to hit 200 BHP mate, xfactor has all of it and isn't there yet. Throttle bodies = new management and setting up as well as the price for the throttle bodies so that will cost well over a grand itself, Cams cost about 400-500 quid.

It is expensive but go for it! I am

[SimonT]

Carbs will cost you about 2k

throttle bodies around 2.5k

For a grand your best bet is a new exhaust, panel filter or cone filter and maybe a chip

cheers

Note Step 1....I'm cheating here, because the engine isn't destined for a Ford at all. Think Westfield-type installation, and you're not far off. Cone filter is already used (due to space restrictions, and the fact that the engine's in longitudionally driving the rear wheels). Likewise the Exhaust is already much better than standard anyway.

Don't think a chip will give me loadsa bhp, unless with the cams. In which case, how wild can the cams go and someone (like Ahmed) fool the stock Ford ECU into behaving with these, or is it throw it away and try Pectel/MBE/Anything similar? Lambda sensor can go in the bin, if the ECU can be persuaded to control in open loop all the time as emmissions aren't a problem (it's a 1985 car).

one word mate:

pinto!

[philhoward]

Oh behave!

[SimonT]

seriously mate get a pinto!

its cheaper and easier to tune.

And suits your application perfectly

[philhoward]

I currently have a CVH fitted, so want to use the Zetec for it's backwards compatability (ancilliaries, gearbox) plus the Pinto is just too tall to fit in there. If i could get better power out of a CVH, then I probably would!

The other alternative is a ZVH route, but fancy the look of that luvverly twin cam head.

If it ain't gonna get done for about a grand, then i'll throw it at the existing turbo CVH lump, but reckon I can't got much further without spending shed loads on it (i.e. Cam, Hybrid turbo, good injection system, etc), so fancied a change and though 2.0 Zetec power. A better base line to start with, being 400cc better. I'm already starting with what a stock RST puts out anyway!

[Mexi]

pinto!

Don't be so pre-historic Simon

[MIK3Y]

U wanna spend a grand on an N/a 2lt Zetec rather than on ur CVH turbo???
Intercooler, Air Fliter, Xorst and chip 4 ur CVH turbo would give u MILES more bang for u buck than buying and spending a grand on a 2lt Zetec IMO!

[Quantum]

A CVH turbo would be expensive as the standard intercooler would not fit and he would most likely need to get a custom made item to fit in the nose cone.

Phil, you may want to check with your local MOT tester about the emissions as a fellow H4 owner who recently upgraded his engine from CVH to Zetec had a nasty shock at MOT time as he needed a CAT to pass the test as the test is on the age of the engine - it is down to the owner to prove the MOT should be done at a lower level for older engines.

BTW what se\/en do you own?

Regards,
Stephen

OK, Time to come clean...The car it's fitted in is a Reliant Scimitar SS1 (2 seater convertible). It came out of the factory with a stock 1.6CVH from a German Sierra, and had a Turbo Technics conversion at 3 months old (1985), blowing through a modified 32DFT carb. I've since taken it up from its as modified 140bhp to around 200bhp; larger T3 turbo, ERST '90 spec ignition, MG Maestro SU HIF44 carb, chargecooler, decent oil cooler, etc...

Been looking at any more ways to get a few more horses (and a bit more reliability) out of it, but don't particluarly want lairy cams or booms of boost. Nitrous would be nice, but you lose the extra as soon as the bottle runs out, and all I seem to do is trying to lose all the extra heat the thing produces.

It's a very tight fit in there as it is, which probably doesn't help with the heat problem anyway, but the oly way i can see to get more power is more cc's.

Would I be better ZVH'ing what i've already got (seems a shame as the bottom end is in excellent nick, having only been rebuilt 4,000 miles ago)?

I fancied going away from the turbo route, as all i seem to be doing is adding weight and gaining less and less... I suppose i'm in the land of diminishing returns now...

Perhaps use half of my stuff and try a Zetec turbo...

[BUTRE]

It all comes to what you want when driving. Loads of power in all rev range, everything dead under 4000rpm and then a burst of power.. etc etc.
I would go any time for a balanced setup on power in all rev range. Its just because I'm more into trackdays then dragracing.

choose first an engine. I would go for 2lts Zetec. Very good head flow. Dont go ZVH!!! 8v CVH head with a bigger cc bottom end... naaaaa

Pinto engine is too heavy! And you can get alot more power from a zetec in all rev range!

Now its up to what bhp numbers you want to achive. If you only want to 220bhp, then I would say go for a ThrottleBodies setup... jenvey 40 to get more trackable power... 45 could be too much and low end would suffer.
There are alot of specialists on zetec engine. Get some phone calls done!

If you go carbs (like DCOE for exemple) you still need an ecu setup for the ignition... and carbs cant get you where throttlebodies can.

If you want 300bhp mark.. turbo the zetec.

Good Luck mate.
