1.8 8v options
I have a old 1.8 8v carb motor, are there any options for me to get it to fuel injection without swapping the head out? ie a intake manifold that has the injectors in the actual manifold.I had a look online and it appears if I had to go the individual throttle bodies way the injectors actually fit into the manifold rather then the head itself but now I would have to get a aftermarket management and a inline fuel pump would individual throttles and supporting parts work out more then just finding a mp9/digifant head,pump,ecu,wiring harness,fusebox and whatever else goes with it.Im just looking at pro's and cons for throttles and mp9.
More background the car,it wont be a daily driver it will be purely for fun I had a look at the turbo route but it requires alot more time and hardware which to me is a waste as I dont want alot of power just something thats fun.
Thanks

Re: 1.8 8v options
Throttles and MP9 don't mix well, MP9 is a MAP based system and throttles will not give consistent MAP readings so you will have to use aftermarket.

Re: 1.8 8v options
Yep I know I would have to go aftermarket fuel management lets say (dictator for examples sake) for the throttles but what I mean is would it be more viable to go throttles or rather scrap the throttles and go a full mp9 system ie the head,pump etc etc. So mp9 vs throttles cost wise,tuning wise,fun wise haha

Re: 1.8 8v options
Finding say, Toyo throttles is easy, finding the manifold is not so easy and you normally end up paying more for the manifold - in my case I paid R1500 for the throttles and R1800 for the manifold. I decided against using them and sold the complete setup for R3500 so I was lucky. Throttels on a 1.8 is going to be tricky, unless you do some serious work to the motor. MP9 stuff is readily available but then you have to look at changing the fuel tank and pump as well.RPGTI wrote:Yep I know I would have to go aftermarket fuel management lets say (dictator for examples sake) for the throttles but what I mean is would it be more viable to go throttles or rather scrap the throttles and go a full mp9 system ie the head,pump etc etc.

Re: 1.8 8v options
I would have to get a complete wiring harness for my GT then cause people for some reason love butchering these already frail fuseboxes and wiring harnesess. I am also guessing I would have to blank off the old mechanical fuel pump on the block.What did you end up doing in the end, mp9?

Re: 1.8 8v options
I reckon start with a single throttle FI setup and take it from there.. Take things easy and slow if you want to enjoy the car for a couple of years.
If you do it all in one shot you'll get bored of the car and sell it within a few months.

Re: 1.8 8v options
why don't you rather go 276 or 288 cam and some head work and klap a pair of sidies with that and have fun.

Re: 1.8 8v options
I would say mp9 will be cheaper to do and will have loads of fun with it.
weather you go mp9 or ITB you will still need
FI tank,
FI fuel pump,
fi dizzy,
block blank off plate,
injectors,
management
etc
ITB
you will need a +- R2000 managament and +- R1000 tuning
ITB's +- R1500
Manifold -+R1800
plus above
Mp9
Harness
ECU
Head + manifold
Prob missed a few things but thats the bulk of it.
My 1.8i with only a 276 estas cam made 98 HP ATW abd was pletty fun.

Re: 1.8 8v options
silly question but since when did we start using hp as a measurement in SA.....? Is it just because its bigger than the kw value?
anyways you can do a mp9 head conversion with head purchase+rebuild, FI pump, cam, gaskets+pipes+filters ect., Management and dyno for about R8k no need to replace tank (just drill a hole in the centre at the bottom and fix in a 90 deg nipple) and harness comes with aftermarket management. and can all be done in two days including trip to dyno of your choice.

Re: 1.8 8v options
I tune on hp becuase the value is smaller you see a movement showing you which way it is going ie. up or down faster in hp than in kw. It's got nothing to do with marketing or **** size or whatever.

Re: 1.8 8v options
well that makes sense to me but when okes talk in hp they might as well be talking in calories/hour, just my preference to talk in kw..... always known it as that, not being european/american and all.panic-mechanic wrote:I tune on hp becuase the value is smaller you see a movement showing you which way it is going ie. up or down faster in hp than in kw.

Re: 1.8 8v options
No need to feel stupid when guys use hp. Just take whatever hp they are saying and muliply it with 0.07457. Most phones these days have at least a calculator.
Oh and 1hp is 178.2659 calories per second so 641757.24 calories per hour.

ill definatly look at mp9 then I wanted to do it originally when my GT was my daily driver but to gather all the stuff was a pain but like 3 years ago a mate of mine
said to me goldwagen used to sell a "kit" where they source all the stuff needed apart from the tank,pump and harness.
Now the next thing would I need to get a 1600 head then and seeing as I have the old style dash in mine which I dont want to change to the new style im guessing ill have to source a wiring harness from a old style dash golf but still fuel injection right?
I believe I have to upgrade the fuel lines dont know if it's true or false and would I have to change the TCI unit and does it need codeing or anything or could I just skip that and go aftermarket ecu other then mp9 or should I just stick with the mp9 ECU?
