The 18R-GTE reference manual ...

[thechuckster]

Yeah, I would agree with that... They are a great low cost item, but anyone can fuck up if they don't follow the manual or do some research first

fixed.

The MSefi ECU is just as robust (or fragile) as an aftermarket unit - what it lacks is the support from dyno/performance shops in Oz as the only source of money is actual labour.

given that the ECU has been fit to all kinds of engines ranging from single-cyl motorbike to a V16 quad cam tank engine (in a mini tractor puller) - and does all kind of duty from frugal and emission-friendly daily-driver to a salt-lake speed racer and hard-core off road buggy - i think it's a big stretch to say that they fuck up easily.

Where things go wrong (like most non-factory setups) is that they require some research and planning and you have to provide the support yourself or be willing to participate in online forums.

Just like toymods, the Msefi forums have little time for people who complain that it 'dont work' yet offer nothing in the way of configuration detail and expect online folks to solve their problems for them.

ok so i got the ecu thingy figured out (get someone else to do it )

now i need to know what pistons you guys are useing because i cant seam to find anyone who makes new pistons for these motors (18rg)

[o_man_ra23]

Chucky, agreed... you just re-iterated and expanded on what I said... they can be fucked up easy... not they fuck up easy.

Slidin, whats wrong with the pistons you have?? Often 18RG bores are fine after half a million ks, as they are hard as, so you dont usually need to bore them out, a hone with a bottlebrush hone should be enough. Just get some chromoly rings and new bearings (new gudgeon bushes are a good idea too). For what you want, higher compression will be a big help. Otherwise, check out the tractor engine thread, as there has been recent mention of different 18RG piston suppliers/manufacturers.

yer its the engine rebuilder im goin throgh he wont put a warrenty on the engine unless i use new pistons i dunno just something he does

but yer cheers for ya help and oh yer could you run a small turbo with the standed efi and ecu????

[o_man_ra23]

No... standard stuff wont account for boost whatsoever... and is poo anyways. A modern aftermarket ECU (even a cheap one) is light years ahead of the factory 18RGUE ECU. Also you will want bigger injectors... the 1G DSM ones teh Witzl mentioned are fairly good price, and plenty big enough for what you want. PM if you want e-ghey links to what I got.

[Norbie]

The biggest problem with the factory setup is it has no ignition control, so you have no means of attaining a boost-friendly ignition curve.

I seriously wouldn't bother with turbocharging if you're not going to install proper engine management.

hey i was just talking to someone that has fittted a 4agze supercharger to his 18rg and he said its piss easy and just as much power and he might even help me with the ecu and stuff ]

do you know of any other people that have done this

[o_man_ra23]

The SC14 are generally quite cheap, and should be plenty big enough for getting some extra oomph outta the 18RG. Just like the turbo you need an updated ECU... but they are not as efficient as Turbos and will use more fuel (if your only going to race, this isnt much of an issue). Definitely another option.

[Norbie]

I'm not sure I'd call it "piss easy" but it's certainly possible. I bought a SC12 and mocked it up on my 18R-G, it will fit but the piping would be fucked, everything is in the wrong place.

BLUEWIRE in adelaide has done a sc 18rg, i woudnt bother with this sc or tc idea if your not going the whole nine yards with management and doing things right the first time. ur up for the part of $5000 put a 1g in it or better yet just go 1j

[o_man_ra23]

18R-GTE or 18R-GZE can be inexpensive if you know what your doing and can do most of the fabrication yourself. If you cant do fabrication or wiring yourself, then 1G/1J is going to be friggin expensive anyways. So unless you either are quite handy, or have a fat wallet that needs shrinking... a conversion will likely be infeasible.

So how are your fabrication skillz??

[Slidin23]

yer me and my dad are good at making brackets and stuff like that just i really get confuzed with wireing looms and ecu stuff thje rest is easy

but i spoke to a few people today and they just said if im goin to all that trouble just turbo it

and iv been down the conversion path before and just dont like it to much screwing around i think

[o_man_ra23]

As an update, I now have an 80% completed MS2, a CT26 twin entry, an 18R-GEU efi set, a set of 1G DSM injectors (450cc fully refurbished) sitting here waiting. Just need to wait on the motor's delivery, and will need to have some flanges fabricated, and get some piping.

Will let you all know how it goes.

LOL I've been in the above situation for about 2 years now.

[The Witzl]

LOL I've been in the above situation for about 2 years now.

me too.... but ive got a working MS2, bigger turbo and much bigger injectors.

(our) engines are being built as we speak
However, mine will be a bit further off as i still need to get a manifold and other stuff made.
