4G63T Auto to maual conversion, Need help :(

[FiEND]

Hi all,

I'm trying to do a engine conversion in my lancer, just have a question regarding the loom.

The engine / loom / ecu i have is out of an auto rvr.

My current setup is fwd / manual.

I'm just wondering how i'd have to wire up the reverse switch to the manual gearbox, and park / neutral sensor (so i can fool the ecu into thinking the car is in park).

Alternatively if anybody has any ebooks wiring diagrams / links regarding this, that would be great.

Thanks in advance.

In all honesty after doing several 4G93T/4G63T conversions into cars I'd tell you to ditch the current loom you have as its not worth the headache nor will it suit without a lot of stuffing around. Get one of the following "MANUAL" engine looms instead and save yourself the trouble. It is soooooo much easier to do the conversion into a Lancer GLXi (which came out 1.8 SOHC EFI) using one of these looms: GSR turbo; Proton GTi/M21 coupe; EVO I-III. Any of these looms will plug into the GLXi interior loom with minor wiring required. If you need something to go by, you can read a couple of tech articles here: http://evocoupe.net/forum/viewtopic.php?f=2&t=3450

Thanks for the info,
Just curious,

How much would an evo loom set me back ?
Since the gsr's are 4g93t's would that still work with the 63's ecu ? or ..?
Would i need a manual ecu as well ?

Either engine loom from a 4G93T/4G93P or 4G63T manual transmission will work. If you can get a 4G63T loom and ECU from an EVO then it would be your best bet. Looms can fetch between $150-$300, the ECU's cost about the same if not more. Second best will be a GSR turbo engine loom which fetches the same price. But its not just the loom you need, there are other parts you require to make it work. Read through the EVOCOUPE 'How To' links above and it will help you out immensely Its always best to thoroughly investigate a conversion before going out and investing in parts that might not work for you (i.e. RVR auto loom and ECU) as you end up spending more in the long run. Forums are a great place to ask questions and learn from other people who have already done it :wink:

Thanks for the info ! I appreciate the feedback. Good to see prompt and informative replies.

Whilst i agree that manual loom would be ideal, in all honesty i'm still thinking of using the auto loom / ecu for the time being, simply because it'll take a fair amount of time to find / source a good loom / ecu. On top of which i already have auto bits

nevertheless i do appreciate your info and opinion.

Also, if running evo loom / ecu wouldn't that mean i'd have to change injectors as well ? :|

From what understand ( and correct me if i'm wrong) the 4G63 used in the rvr's have a different cam profile as well as different sensors, using evo loom will really work with this engine.

Or am i misinterpreting something ..

Don't mean to rain on your parade, but its heaps easier (and wayy cheaper) to buy one already done or OEM DOHC turbo......

as if.... doing it yourself would only take 5 mins, think of driving to the mechy, getting someone to drive you home and then take you back..

I totally understand, but i'll put money on this being the last time you do it.

One more question for you, I wasn't aware that the M21 has a turbo engine, therefor the loom/ecu wouldn't be of any use for me ?

I can get an m21 (staria?) loom/ecu out of a '93 model car but it's N/A.
Will this work on the 4G63 ?? *Confused*.

Thanks in advance .

You didnt read the DIY links I posted earlier did you?

The pre 2003 (Mitsu ECU'd) Proton GTi's and M21 coupes run a 4G93P DOHC 1800cc engine (non turbo) variant of the GSR 4G93T engine. The engine loom in these model Protons are essentially the same as a GSR turbo loom and can be used to run 4G93T's no problem. And since we all know that 4G93T looms from GSR's can run 4G63T's with a little bit of modding to the wiring so will the Proton engine looms

The aim of the game is to make it as easy as possible for you to do your converison. The easiest way would be to get your hands on an EVO I-III engine loom and ECU. Failing that if you can only locate a 4G93T/P loom then you will have to read the 'GSR to 4G63T DIY' to find out how to wire the 4G93P/T loom to suit a 4G63T. The DIY is pretty comprehensive and has step by step instructions.

If in doubt get some experienced help because a lot of people who havent ventured in it before go in with all good intentions thinking they can do it but they end up back on the forums asking question after question when things dont work... and that's why the DIY is there for in the first place :wink: Plus it also stops this (I just made this up :lol: )

Yup, i did read the info on the link, just wanted to confirm i didn't misunderstand.

I was under the impression that fuel mapping between N/A and turbo was significantly different since air / fuel mixture is increased.

Thanks again .

It is, but we're talking about engine looms not the ECU's. You will have to run a 4G63T ECU whichever engine loom you decide to use.

That 'Newbie' pic you've posted is fucking hilarious Rob!!! :lol: :lol: :lol:

Hokay, that's what i wasn't sure about, hence the questions.

At this point i'm also guessing the ecu i'll have to use would have to be out a manual version car to suit my wiring ?

Simply put the auto ecu / loom i have is not really usable ?

Whilst these may seem somewhat silly questions i'm trying to make sure i'm not jumping the gun, and getting things i don't need.

Thanks again for your info.

Not necessarily mate, I used the Auto VR4 ECU which came out of the half-cut I used to get my 2.0 which I mated it up to a manual transmission. My mate actually thought the auto ECU made the car a little more aggressive, as he had a manual VR4 ECU in his car hooked upto basically the same engine. I hadn't driven his car enough to really notice any difference personally.

You might be able to find, or adapt, a clutch switch for the park function, ie, when you push the clutch in, the ECU sees "park" and the car will start.

It would be complicated though cause you would have to make it so it's disabled when the engine is running, or else the car will think it's in park and driving at the same time... dunno what the consequences of that would be.

Alternatively you could just have a "park switch" on the dash, flick the switch and the ECU sees "park", and you can start the car, then when you want to drive just flick it off. And the last idea I have, wire the park circuit into the ignition circuit, so when the key is in the "start" position, the ECU is told the transmission is in park (ie the key is the "park switch").

 

[CLuTZ]

You dont want to press the clutch in while you start a 7-bolt motor. Hello crankwalk.

Considering RVR's have a seperate transmission ECU, couldnt you just leave it off?
