just been thinking, why is it most commenly the frst inlet that is used on a ZT??

whats wrong with the alloy one, and the later plastic style ones???

is it simply cos the zetec injectors are poo, and with the frst inlet you can use different injectors?

 

I rememebr somebody saying the RS1800 inlet manifold was the best Ford one to use. Can't remember who it was though.

 

 

cheers adam, but finding a rover inlet is a mission in itself...

oranoco, the rs1800 inlet it the alloy over the top jobby as found on all early zetecs.

but decent ie end fed injectors dont fit directly.

although for my throttle body conversion i have made a custom fuel rail to use cossie injectors on a zetec inlet

 

Adam, top quote mate

Dan, I dont like using FRST ones (see above ), I dont do the adapter plates for them, but Lewis said the oens he has looked like they'd been engineered with a spoon

PM Red16, he has a Rover manifold for sale

 

well, basically i had the idea of doing a cheap as poss ZT not worried if it goes bang either, just to see really if it will work!!

instead of using a decomp plate i would get the pistons skimmed 1mm, yes i know everyone says it wont be reliable/shit

but how many peeps have actually tried it??

not many i bet!!

is 1mm enough tho?

cant remeber if its 1mm for zvh and 2mm for zt??

anyway, i can prolly get all the machine work done just want to know why the alloy zetec inlet is not used?

 

Mainly due to the fuel rail mate .

Be a good little project that bud.....I used 1mm machined pistons (7.8:1) in my old ZVH. I'd rather have machind pistons anyday over a spacer plate, at least you have propper sealing between head and block then!.

If you need any help mate, jus shout PS. is it a 1.8 or 2ltr?

 

yeah, will skim them not use decomp plate

prolly do a 1.8 mate as they are easy to get and piss cheap.

no doubt ill catch you on msn mate at some point.

also the fuel rail i made to use cossie injectors on mine for the tb's wasnt hard....

 

oh, do you know what cr i will get from a 1.8 zetec with 1mm skimmed pistons??

cheers bud

 

1mm = 9.2:1
2mm = 8.5:1

Calculated. Measured may vary

 

cheers mate, although, you cant take 2mm off a piston can you??

and is 9.2:1 too high?

only aiming for 200 - 220ish bhp?

 

Find a set of Calibra turbo pistons mate 7.4:1 and very cheap if you can find um!

 

that means 2.1 tho dont it??

i just want to see what a stock engine is capable of with skimmed pistons.

fed up of peeps who have not done it saying it wont last 5 mins, fair enough, if it does go bang i would have prooved it.

and as i said, im not worried if it does.

just as an experiment

 

unless i use a CVH head and skim 1mm hmmmmmm

 

i'v got 1mm skimmed standard pistons in a 1.8 16v zt. i use the zetec alloy inlet with a frst fuel rail. not done any miles yet. like you i am only looking for 200 -220bhp.

 

i dont no what a rover one looks like inside but a zoo plenum with 45mm ram pipes with bolt on to zetec throttlebody inlet with ease

 

not quite sure of the thinking here....

skimming pistons... they potentially take the lot out...

decomp plate or copper gasket perhaps... it fails..... erm??... shouldn't do owt.

what richm and tony pastie did seemed to be effective for 200+bhp and relatively cheaply.

how hard is it to put the FRST fuel rail onto the zetec?? as ive got a 1.8 zetec doing fook all at the mo and a more than enough spare FRST bits and pieces!! hmm

 

and how much???! any pics?

 

use a caveleer 1.8 8v fuel rail and the zetec fuel rail and stick cosie injectors inbetween

il take a picture of one i did earlyer

it works because i used them on my 2.0 n/a fiesta with a fse fuel regulator

 

took me about an hour to do and cost a fiver

 

its not difficult. remove zetec injector rail and injectors etc. u have to machine out the holes where the injectors go as the frst fuel rail puts injectors in at a slight angle. u then have to weld a couple o brackets on to inlet to fix rail onto.

 

i have done one already i will get customer to email the pics
its a throttlebody inlet with a zoo style rst plenum cover with 45mm rampipes inturnally and a cozzy thottlebody at the end
all polished
and bling

 

anything like this brom ?

 

yes that sort of thing

 

Dan, IMO you are going to need to find 2mm minimum - have a look at how thick the standard CAST piston is and then see if you really fancy taking that much off..
Fair play to you for wanting to actually try stuff to find out what it ACTUALLY does though

What are peoples EXPERIENCES of decompression plate failure? seriously, I'm interested in real experience, not pub talk..


mrviper - nice work with the Cav rail!!

 

there fine with a 1.8 but 2 litre are wider so break a bit easyer i have been told your ok for 200bhp if you get the car properly setup so its not runing lean/geting too hot

also been told no problem with 10psi

i bought a decompression plate but went for pistons so i could run shed loads of boost and rag it around a track

so if you want a 2.0 decomp plate drop me a pm

 

whats that small pipe going in to the crossover pipe where the temp sensor used to be

just trying to find out what the best breather setup is for a ZT

 

any know or used a frst throttle body on a zetec inlet manifold?!?!

 

feed out to the Idle Air control valve.. nothing to do with breathers..

 

cheers guys, i have have decided to go de comp plate route as if it does blow the gasket its far easier to replace, unless the whole thing goes bang lol.

ive got an astra 1.8 sri in my garden so ill rip the fuel rail off that and have a look.

here is the fuel rail i modded for my TB's







for that im using saph cos dark blues

 

how did you paint that rocker cover ? looks brill

 

yup! got one here with the adapter plate fited to it so i could use my cvh management with a 2.0 zetec engine

 

i removed it because i installed omex on my car and had a 2.0 tb laying around from when i got the lump from the scrap yard

oh yeah and there is naff all diference in the size of the throttle between 1.6 cvh and 2.0 zetec

 

wicked, just what i wanted to hear...

tried saving your pic's mate, but it won't come up when i open it, have to use another program to open it.. but still no luck

 

rigth click save file and make sure that it has the .jpg extension at the end.

 

i ripped the fuel rail off the astra pile in the gardn yesterday, looks the same as yours mate, bit of gringin here and there lol and its about done

not pics tho as the missus has left the camera at her school....

did you weld on that bracket to hold it to the zetec bit?

all i gotta do it sort out the brackets and thats it.

 

yep weld a bit on mate and clip the injectord on with the clips and bobs ya uncle!!

i can post the throttle body to you to copy id you like then post it back to make life easyer !

sorry about the delay in posting!

 

no worrys mate

do you need to use the FRST TB then??

is the throttle pot different to zetec?

 

IMO the FRST inlet works perfect!

I have seen the VERY BAD conversion plates for the zetec which made me make my own for this car.



Once you have a FRST/EFi inlet most other componets are industry standard fittment (ish)

 

PhilMhey we never had a problem sealing it up mate depends what you use and nobody to this day has worked it out yet heres a clue it comes from the states
