Engine Conversions - Anybody actually know what is possible?

mrx · Post by **mrx** » Tue May 17, 2005 12:42 pm

I know this has been discussed on and off, and there is even the "turbo Conversion" thread going on at the moment. However, does anyone actually know what is possible and what isnt?

6A12TT - same family, so should minimise the wiring problems. However, the gearbox is on the other side, but what if you had a half cut with gearbox, drive shafts etc? It would take more time, and cost a little more (due to labour), but surely it isn't overly difficult?

4G93T - It puzzles me that it is considered relatively "easy" to put this engine into either a Lancer or a Mirage, and it is also fairly "easy" to put the FTO V6 in those cars also. However, people say it is very hard to put the 4G93T into the FTO? This does not quite add up to me. Also, the GS had the non-turbo engine, so in theoryit should drop "straight in". There may be some wiring issues though.....

4G63T - Gallant/Evo engine, which shares the same platform as the Eclipse and the FTO (as does basically the Lancer and Mirage for that matter). Would this be possible? Not hard to get half cuts for this. Anyone looked into this?

6A13/6A13TT - Said to be the easiest, but rare as hens teeth! Anyone know where to even find one? Price? I believe that Jeff posted previously about what was needed to be done to put into FTO, but what would it cost?

Having said that, sticking with the MIVEC engine is kinda what the FTO is about anyway. But just looking at options, and I cannot logically see why some of the above are considered impossible to achieve. I know that anything is possible, given enough money, so please don't post that

. I am after some factual information here, and I am sure that others would be interested too.

6A12TT wont fit (wrong side)
6A13 and TT version will fit
4G93T will fit so long as it's a CE version (you gotta use lancer mounts)
4G63T will fit again so long as it's CE version (evo 4+)

Alternatively, if you have the MIVEC 2.0 already, you can put the 2.5L hybrid 6A13/6A12 with the MIVEC heads and make it go quick without a turbo

I am opting for this one!

Or if youv'e got some big bucks drop in the 8A80 alloy block front wheel drive V8

(would be a very tight fit)

Seriouly
I think that another engine transplant that has been overlooked is the 6g72 MIVEC 3.0ltr (200kw)

I would think this would fit as it has a shorter stroke than the 6A13 but a bigger bore. So it should be around the same weight.

Any thoughts on this?

The 6G series of motors are much bigger physically than the 6A series, so it would be a bit of a squeeze. Remember that they go out to a maximium of 3.5 litres, so they're quite a large engine. I would think that one of these in the nose would ruin the handling somewhat...

An 8A80 - thats an interesting idea! Only trouble is that they are a GDI motor, and GDI has its own problems.

I remember a post from Peter at Kempys on NZMMC once when he talked about a project they were going to do which involved putting a 8A80 into an FTO - would be interesting

. This from the same people that made a rear-engined 4WD Cordia rally car powered by a Chev V8

You can only go so far with small engines with turbos or VVT etc before, you need some big displacment.

you think the 6a13 is hard to find, try looking for the 8A80

It would be easier to find some rocking horse sh*t

Yeah it isn't used in many cars, as its mainly used in the top of the range expensive cars.
I know that Hyundai also use this engine in a few cars as well

Yeah, but is it actually done? RPW are not reknowned for always following through with their projects - for one reason or another. And I am not saying they aren't valid reasons!

How much of a problem would be wiring etc with (say) a 4G63?

i can generally source 6a12tt halfcuts if people are serious... if you are pm me (let me know where you are) and i'll get a quote for 1/2 cut and delivery

CSV · Post by **CSV** » Tue May 17, 2005 11:20 pm

Yea I'd be very interested about those halfcuts...let me know the price...

So with this hybrid 6A13/6A12 thingy, what soughta price r we looking at for that one?

mrx · Post by **mrx** » Wed May 18, 2005 9:09 am

But what is the point of a 6a12tt if it is the wrong way around? Can it still be put in? Do you just use the gearbox, drive shafts etc aswell?

afterburner · Post by **afterburner** » Wed May 18, 2005 10:19 am

Well the 6A12TT comes with a 4WD gearbox (the same W5M33 as used in the Lancer GSR and Evo series), so that would be useless. If you really wanted to use a 6A12TT you'd have to get a FWD gearbox from a 92-96 Galant Viento or similar, which are FWD 6A12 N/A powered cars.

But it would be a hell of a lot easier to use an engine which is around the right way to start with...

to4garret · Post by **to4garret** » Wed May 18, 2005 12:02 pm

why not transfer all the insides from the 6A12TT into the MIVEC motor, including the turbos etc.

that way you could get the engine rebuilt with new bearings/rings etc. hangon, the turbo's would face the wrong way too, i would imagine about 90% of the intake plumbing would not fit also.

ekkkk, sounds expensive

Black_FTOGPX · Post by **Black_FTOGPX** » Wed May 18, 2005 12:30 pm

One other option that would be a direct bolt in for a GR is this.

Kempyâ€™s had or still have some 2.5 ltr 6A13 dohc test engines, which were never officially released by Mitsubishi. According the Peter these engines are a NA version of thew 6A13 TT.

He said that it has heaps more torque than the 6A12 and he says that it kills the 6A12 Mivecs.

But because this engine was not officially released there are no power figures or Stats on the engine. (Really need to get him to Dyno his car)

Well there is a mainstream 6A13 N/A motor - it comes in the 96-onwards Galant and Legnum. These are reasonably common over here. They have less peak power than the MIVEC 6A12, but a bit more torque. They are longer stroke so don't rev as well as the 6A12.

Yeah but that is the SOHC version, which have 130KW.(I think)
So in theory the DOHC version should make more power and more torque.

when my engine blew i ahd a long hard think about how this all worked out.

the evo engines with lancer mounts realisticly offer the besst power/weight compared to the 13tt. the thing every one forgets is when you dump in the 13tt's is your dumping in a fair bit more kgs into a already nose heavy car.

as (i am told anyway?) you cant stroke the mivec engine

but one very itneresting thing i read about recently might brin some light to the situation

apparently some people strapped a turbo near the cat on a es300 lex to save on engine room and make pipeing easyer due to the exhaust channel, it has been kept relativly safe...

has anyone else looked into this? before? becuase i knwo the biggest issue with turboing the stock engines is hte lack of room and pipe flow

There's definitely a DOHC version - we have it in several models of Galant over here. Kempy's sell lifter kits and RPW do extractors for them so they must exist!

I still dont beleive it

I thought all the official NA versions of the 6A13 were SOHC.

You better get some evidence! While i get some to prove they dont exist officially!(joke)
