throttle bodie's

20th July 2009, 10:46

right im going to start this off by saying i do not want the usual this is a waste of money just put a vts engine in or why spend all that on this type of engine or you wont see much gains past late spec vtr i know all this already the purpose of this thread is to see if it is plausable and get some detailed advice about what i want to do. as i want to be different and the car will never be sold so why not.

now with that out of the way id like some info on throttle bodying my mk2 3 plug 1.1. it already has the usual breathing mods mods but i want to go a bit further with tuning and avoid the usual r or s conversion.

all usefull help and advise is much apreciated. also if you could include where to get certain parts and rough prices cheers in advance stu.

polishing a turd really.

But the port spacing on the 1.1 is the same as on the vtr iirc so you could use an inlet manifold from a vtr throttle body set up.

But then you need an ECU + mapping. So why are you contemplating spending 1500-2k (as really you are budgeting for this) for what will be very minimal gains.

You will probably be better off getting a custom grind cam aswell to get the best out of the set up.

yeah i get that id have to spend a bit but if i could afford it it like to have a car thats different. and where abouts would i go for a custom cam? for the ecu could i use one from a 1.1?

20th July 2009, 11:08

possibly see better gains from a turbo set up, but dont see why tb's couldnt be done the same as on a late vtr engine

20th July 2009, 11:12

dont realy want to go the turbo route n/a ftw

you need a standalone really. People can map OE ecus, but theres still alot of debating about how good the map will be and how many load sites are being used.

Throttle bodies = not a cheap engine option

Any cam maker will make custom grinds if one in their range isnt suitable for what you want

ok cheers ryan. i thought id need a standalone im sure the 1.4 pred could be adapted.

Speak to andy see what he says.

Either way still £500 for an ecu iirc inc mapping, then you have the cost of the bodies ontop + setting up + cam if you want better gains.

I dont see why you are intent on being different, its just pissing into the wind. A vtr engine on the same set up would give alot more scope for power, and the vts even more which is why people go that route.

20th July 2009, 11:39

i know will prob end up going down that route but would just like to get all the info i can as. id realy like to do it.

as ryan said... pising into the wind

you wont feel much gain from it TBH,
it would be a waste of 2 grand imo

read the first post your opinion is your opinion but i dont want peoples opinions in this thread i want advice.

20th July 2009, 11:51

honestly?

it wont be no where near as easy as fitting them to a VT engine as theres alot of adapting to do,

first you need to either unlock your OE ECU which personally might be the biggest wast of time or find a sutable 3rd party ECU, that will work with the 1.1

secondly you need to buy a set of VTR boddies, plus fitting

TBH from just that you wont gain anaything really... maybee better throttle respones and 0-60 time.. nothing exiting

then to make the most out of the boddies your looking at finding someone who can customise a cam for you, as most cams are made only for 1.4 and vt engines.. alot of messing about there tbh

after that you need to think about RR time and mapping? few hundred quid there..

oh and after that, if you decided to be heavy footed for long pieriods you will find an engine rebuild is in order, as smaller engines arnt designed to take stress like what boddies and cams will put on the engine

for the price your looking at to do all this?

you could buy and insure a decent VTR

i have been a mechanic for years now but if you really insist on doing this to your engine, ill happily answer any question and help you along the way

thank you thats the sort of stuff im looking for other wise it will just become a asw thread

20th July 2009, 12:26

like i written tho it can be done.. but for the gain its more of a " is it worth it"

any questions drop me a pm

20th July 2009, 13:26

tbh if i do it. it wont be for the power gain just for the individuality id be happy with late vtr spec iirc is 98bhp.

20th July 2009, 13:59

unless you are building the car for a motorsport class then there is little point. Just fit a bigger engine.

the 1.1 comes standard woth 60BHP

the VTR 00> comes with 98, round that up to 100 to keep it simple

therefor to get to VTR standard, your going to need to find 40 BHP

thats not going to be the slightest bit easy..

if you spend 2k plus on all these perfomance mods your looking at

your still likely to be slower than a standard saxo VTR 98

personally its up to you what you do with your money,
were here to help you from wasting it
