18rg turbo

[DQIKST]

I would imagine that bolting on a turbo + intercooler etc would pretty much negate the existing carb induction sounds you have.

was talking about the efi conversion and the fact i wouldnt have many hic-ups.

but im with you.

still the carb note is good not overrated at all..

but every one to there own i guess

You can shop around at wreckers and the net ( ebay and toymods. Im sure the blokes here would have most if not all the parts you need.)
Its not always an option cause some can nt afford conversions and have to make do with what they have.

Im pretty sure you would loose most of that carby sound with a turb

well since you are getting the efi bits for the turbo, are you going to upgrade the fuel supply at all? or just intend to leave it standard? i suppose the more demanding question is how much psi/power do you want, and how long do you want it to last for?

O: did any of those two cars come to fruition? ( the gas powered and the ghetto carbi+turbo T-powered celicas)

[oldcorollas]

been thinking about wacking on a turbo to the 18rg ( carbie) n wanted to know the pros n cons of this situation...

would like to know the best way to go about it
best parts to use as this will be a little backyard project
cyaz

pros. more power.

cons...
a), you seem to not really know much about engines in general, so i suggest (in the nicest possible way) to start looking into how engines work, and then you will have a much better idea of what is required

b)

and i do belive you can get more power out of a carbie turbo

this also appears to be a problem. refer to a)

c)

i dont think it should be that hard. just need to get a custom manifold made to suit the solex carbs n we can wak on a t2 or some shit..

again, refer to a)

d) if you go efi TURBO, the AFM and stock computer will be next to useless, as will the standard injectors.... in fact the only useful thing will be the manifold, fuel rail etc..
you still need to get pump, change all your rubber fuel lines, get bigger injectors, get aftermarket management, make up exhaust manifold and everything else...

e)

it doesnt bother me i would just like to have a 18rg turbo so i can whipp some rexxy ass
the guy sed something about water to air injection or some shit like that.

chances are that you will not be Whipping any rexxy arse. seriously.
the guy is having a lend of you, or your short term memory is in error


on a VERY VERY serious note, GO TO A WRECKERS and stick your head under a few bonnets. have a look at an EFI 18RG. have a look at other EFI motors.. heck, just look at a few motors in general!!

then go look at some factory turbo setups, see what they do etc... to be brutally honest, if you can't tell what you are looking at when you look in the engine bay, then a turbo conversion is probably not for you...

however it doesn't have to be all bad
EFI manifold and TB
injectors sized to suit your requirements + fuel rail/damper/reg
return line big enough, and change all rubber to EFI spec (yes.. use NEW LINES)
make up a loom to suit your aftermarket computer... it's really simple.
make intank EFI pump. don't buggerise around with surgetank... really...

connect manifolds and sensors to engine, connect computer, connect fuel lines, do a quick base tune, then take it to dyno to be professionally tuned
sure it sounds simple (and it really IS for people who know what they are doing), however in this particular case, it will be much much harder than you or your "mechanic" think.

carby turbo = messy and dangerous and no need to do such things in this day and age.

heh, bogans.


u said basically what i was thinking, iv been down the road before... carbies suck(pun ) and trying to make a motor what it wasnt originally is expensive and time consuming.

[oldcorollas]

heh heh, thats what we are here for right?

however, a line must be drawn somewhere regarding sensibility/practicality/common sense, and one must realise ones personal limitations/bank account max overdraw

[whatthe?]

and trying to make a motor what it wasnt originally is expensive and time consuming.

Yeah, but gee it can be fun!

Edit -Doh!

Hi,

I've been watching this thread with interest and a few times I was going to comment, but I decided against it. After all, you're talking about the wonderful 18R-G and that will always get my attention.

I got to agree with the above comments, that you should use EFI if you want to turbo your 18RG. Sure, you can turbo your carbie version, but it will be easier and less hassle if you use EFI. Also, you should use the 18R-GUE version of the engine, which, due to its lower compression, is better suited for turbo - as opposed to the higher compression 18R-G model.

Then, you will need the after market ECU and you'll also need to strengthen your engine, your gearbox and your diff and better brakes will be necessary. Of course you then have to have your feul delivery system upgraded for the turbo/EFI set-up.

Yeah, it's fun to do this to an engine, but don't kid yourself that it will be inexpensive and not fraught with pitfalls and moments of despair and anger. Nor will it be something that will be done quickly.

As far as beating a Rex.... well, what do you mean exactly? Do you mean straight line speed, or handling, or looks? For speed you will need a very powerful engine and although it may be possible to get the necessary power out of a turbo'd 18R-G, then you'll need it to be a top notch (read very expensive) and comprehensive engine rebuild. If you want to take on the handling, then again this will require a truck load of money to upgrade and tune your suspension/brakes.

As for beating a Rex for looks..... such comparisons come down to personal opinions, so it's not possible to provide a scientific and definitive winner. Personally, I find the Rex one of the most unattractive cars on the road and any 1st gen Celica beats it hands down for body style and shape.

thanks for the comments old corollas but that was the whole point of registering to the forums n hopfully becoming a club member(when i get my licence back)

i never thought about fuel lines but u did relise that you would need to do a complete engine rebuild so that it could handle a turbo..

on a VERY VERY serious note, GO TO A WRECKERS and stick your head under a few bonnets. have a look at an EFI 18RG. have a look at other EFI motors.. heck, just look at a few motors in general!!

i dont know about you but i barly have time to play with my self let alone go to wreakers which mind you havent had any 18rgs'.

its all good every bodys input was valuable and has taught me to belive only 10% of what comes out of my mates mouth. because i see it wasn't going to be a cheap weekend job.

so the turbo upgrade is in the trash can but is it awfully hard to convert my 18rg to and rfi set up???



thanks

EFi do you mean?

I'd imagine it's just a case of getting the EFI manifold, loom, injectors, computer and then othersensors and you'll be on your way

that said, my performance setup has SQUAT to do with EFI.

Go LPG mate.. Much more fun, higher octane, less pinging, more advance.. Oh the joys..

[Norbie]

An 18R-G EFI conversion is dead easy, IF you can find all the bits. I had a hard time sourcing the EFI hardware when I did the conversion, and that was 7 or 8 years ago. Obviously it's going to be a hell of a lot harder now! You might get lucky though, so keep your eyes open.

Hi,

If you got the old style original 18R-G engine, with the twin Solex, then get them rebuilt and retuned. EFI will not provide you with better performance or more power for your daily driving.

I don't know how much it would cost to convert your engine to EFI and have it tuned, but you're looking around $700-$800 to get the carbs fully rebuilt and tuned. Oh, and make sure you go to someone who knows these carbs 'cos they are fiddly and difficult to tune properly unless you know what you are doing. Once the carbs are done properly, and I mean properly, you'll love them - hot starts, cold starts, nice idle, easy & smooth engine revs and good economy when driven sensibly. However, poorly tuned carbs are shit and can give you all sorts of grief and lack of performance and poor economy.

river if i was going to do the efi conversion i would have only done it for the economy.

but if you put it like dat
Once the carbs are done properly, and I mean properly, you'll love them - hot starts, cold starts, nice idle, easy & smooth engine revs and good economy when driven sensibly

do you have any contacts from where i shall be able to take my carbs to get tuned???
