depends what you want from the car, a project that will rev like buggery and go well then tune the 1.6
a car that goes well on motorways etc... then fit a c20xe
the 1.6 is not the easiest option and as far as im aware you cant keep the air con.

SRi-Co, that interesting to hear! Is it the XE lump you have in yours?
If i were to put an XE or XEV in, would i need to change my front FK Supertec springs or could they handle it? Id i reduced the the weight at the front with bucket seats ans maybe a carbon bonnet or something!
Can you retain aircon with a 2.0 conversion?
Cheers mate
yeah i'm running an xe, using bilstein shocks and some 40mm springs upfront, no anti roll bar either. Its stable even at speed and doesn't understeer anything like it did before the 2.0 went in. Had a few handling issues at first, but that's because i had a balljoint fail

dare say you're right, its just some people give the impression that the 2.0's just don't go round corners, this isn't the case

it sounds like there are strong arguments for both the 1.6 and 2.0 engines. I think i am probably more likely to tune my current engine as it seems a shame to get rid of such a new engine and one in such good condition.
Do people rate the mantzel jobbie over the dbilas one? the dbilas seems slightly more expensive but is tehre much in them?
Am i right in saying it is about £400 for having a unichip fitted and set up?

I have just started gathering the parts I need to throttle body my 1.6. I have been telling Broster I dont want as much power as he has but he doesnt realise I am aiming for 182bhp

That was my point exactly. My engine has done 49K, more than half of that I have done. So I'll keep that and not put a ragged to fcuk C20Xe in it.

yeah i think thats a fair point Dean! nice one! if i wanted someone to fit the manifold for me, how much do you think it would cost? and how about the dastek unichip fitting?
cheers

The unichip i've only started to look into myself. So i'm not too sure.
The mantzel took around 4 hours. Ignore my previous post, I was thinking of the wrong part.
I payed £80. Most garages I took it to said they didn't want to know, or quoted me crazy money. I ended up taking it to a guy who I used to work with. You could do it yourself if you have a bit of know how and patience.
The hardest part was re-routing all the coolant hoses, taking out the plastic inlet round the back of the engine and hooking up the vacum hoses.

ive had both a mantzel inlet se-up, and currently tb's. more info:
my old spec:
fully rebuilt x16xe
mantzel
gas flowed head
matched inlet
enlarged throttle body
janspeed
manifold
de-cat
exhaust system
de-restricted airbox
k&n
custom management and loom
arp rod bolts
sbd rollers
and a few other bits...... 155 bhp @ 7350 rpm
Current spec:
fully rebuilt x16xe
gas flowed head
Novatech 40mm taper throttle bodies
speedex 30 degree inlet
janspeed manifold
de-cat
exhaust system
pipercross filters
omex 500 management
home made loom
arp rod bolts
sbd rollers
was around 160 bhp @ 7500 rpm but feels a lot better with the new speedex inlet and im getting some verniers next week, then off to noble motorsport for a re-map on thursday
If you look at it, there isnt much difference in the figures, but it not all about the figures its how the car drives. the mantzel did produce 155 bhp, but power only came in after 5000 rpm. with the tb's its there from 2000 rpm.
by the time i was happy with the mantzel set-up i had spent as much money as the throttle bodies would cost. my advice would be to save up and get some tb's second hand. i sold a full jenvey set-up recently for £700 and all that would be neede is management and a loom on top of that (about £400 second hand)
to sum it all up, if you want good cheap power, get a mantzel and stop there. if you are going for unichips etc... wait and get tb's. the mantzel route is a bit of a dead end and not a 'real' 140 bhp in my opinion.
as for the 2 litre conversion, i have done a few and the handling isnt as good as a tuned 1.6 and they are nowhere near as much fun. My corsa out handles and out performs my mates 2 litre corsa in every way.

that is interesting to hear, cheers corsa808! How much would a full jenvey set up cost?
thing is by the time i can really afford to do much to the car, it will be a few years down the line and i will probably be coming around for a car change!
Did speak to SBD a while back and think the price was around the 2k mark without fitting!
I would love to install throttle bodies, but i fear i might not be able to afford it! any info would be great,
cheers

me and a mate fitted the inlet manifold on my old engine. nothing too tricky, allow yourself atleast half a day though. Got amazing results too. took it out and it was so much quicker high up the rev range! Had it rolling roaded before and after and showed a 23 Bhp gain. that was with an exhaust system and without touching the engine management. well worth it

wow, was that with the mantzel? thats a cracking gain! think i will probably end up going down this route, throttle bodies are just going to be out of my price range! was it jsut top end there was gain?

23 bhp gain?
so managed 130bhp without management etc, thats well above most. expect 120-125 with just an inlet and exhaust.

this is such a good read as im jumping onto 1.6 thats with manztel and enlarged body does the enlarged body make much of a difference?
only thing is ive never driven the engine before the manzel so i wont see a difference but basically i wont notice it unless i get it chipped?

Was thinking of doing this with my other mods.
Do you think it's worth it?
Courtenay say more throttle response blah blah blah.......
Any gen?
