an interesting conversation. I seem to think along these lines ^
I understand A2 may have the best intentions and is a small business. However.... If you can't bring it - you shouldn't be offering 3000 products. I would only offer for sale what I had in stock, or knew I could get/produce w/in a week or so. Either you provide a product/service, or you can't. If you're specialized (like in lancers) that's fine but I would never buy an empty pint of beer you know?

 

simple it doesn't fit up. i used to go on about it but relised it doesn't fit.
the only way it might fit is sourcing a 4g94 DOHC GDI engine from japan out of a Galant and swapping out pistons and conrods and using the DOHC or the DOHC Mivec head but either way its not worth the expense as your still FWD and problems with traction

 

so here's a question, then. For N/A guys who are slowly building up their car, and then hope to someday add turbo, what are the best mods? I've got intake, exhaust (it would have to be a little bigger for turbo). My next mod I'm planning was going to be bored TB and/or PP intake manifold.

I guess, to say it better, what N/A mods will hook up nice with a turbo down the road? what should I avoid (i already spent a lot of $#$ on my headers...) I don't want to drop a lot on NA parts if they won't, someday, compliment the turbo

 

4g92 fits the mirage. Are you sure it would fit lancer?

 

GOOD:
- Bored TB
- Bored IM
- PnP head
- Cam
- Piggyback
- Pulley
- Fuel rail

AVOID:
- Intake mods (turbo will completely remove them)
- Exhaust mods (turbo will need bigger)

That's about it. Just went down the RRM product page. Obviously little stuff like plug wires, motor mounts and a flywheel are fine too, but I stuck to real engine mods.

 

And when you guys exchange the pistons, did you exchange the rod bearing? Anything else?

 

You are saying the head doesn't fit the block? Or the entire engine wouldn't fit the car? OR both?

I have a hard time believing the whole engine wouldn't fit since the 4G94 used in the Lancer is almost identical to the 4G93 used in the Mirage, which is the same car the 4G92 was offered in. But I can understand the head and blocks not being compatible, but at the same time to even attempt a GDI head swap would be something I would avoid entirely. I coudl see that head/block frankenstein combo not being possible at all because the blocks would be different too. The likelyhood of succesfully using a GDI setup on our gas would also be remote.

 

ok there is two block in the 4g9 series of engines SOHC Block and DOHC blocks none of the head componants swap over betwen the two (or so i have been told)
all the 4g9 engines DOHC And SOHC will fit in the CS5 chassis (CG/CH Non-mivec chassis, (remember im from AUS))
yes your right about the GDI there is way too much sulfer in our fuels for them to run right but i don't like GDI's anyway because there very hard to tune and you can't do much to them anyways.

and in the end why spend so much money to get a head that will increse power by 20-30hp (turboed of course) when you going to have a hard time with traction anyways
but if you wanted a Mivec 2.0L there is the FTO Mivec engine? sounds kinda like a skyline and does a 14.5 down the quarter but its very nose heavy so plently of oversteer on the track

 

The new 2008 Lancers have a 150 HP 2.0L, DOHC MIVEC. I wonder if that fits and can be swapped.

 

i doubt it

 

The swap will cost a lot because all the engines will be new.

 

2 factors:
1) A 5g mirage & modern lancer's engine orientation for the true G93T and G92 MIVEC is ultra rare (more rare than an ITR motor).

2) no salvage yard will part off the head. Therefore, you have to buy the whole shabang. If so, the cost will be sky high to deter corpsing up the motor. 1 grand w/ S&H for a stock head???

Only 2 miragers that I know have their physical hands on a G92 MIVEC. One is in the military (unknown status currently . . . haven't heard from him since spring or summer) and another guy (I'll to hope to bring him to this thread or make a new thread).



See. This type of Q makes me cynical of your mods.

It's like saying "will a SR20DET or RB20DET fit in a 240sx" to a bunch of 240sx owners. They will stone me w/ rocks to kingdom come.

 

Okay, that's usually true for other manufacturers, but I am used to the 4G6X series where you can swap heads between sOHC and DOHC. You do have to fill some of the passages in the SOHC blocks though, so maybe that is what has to be done with the 4G9X, or maybe it has to do with the guides for the belts and pullies that makes them incompatible. The 6G7X series is the same way, as in DOHC and SOHC are generally incompatible.

Then why modify a FWD at all then. I have a 290whp FWD car and now I'm building it for 375whp. I don't understand why a high revving DOHC MIVEC Mirage or Lancer with about 200whp wouldn't or couldn't be fun.

I would think an FTO swap would make things even more complicated, which is I why I just suggested a head swap. But if you have to buy the whole engine like bahamut says, then why not. I don't know if the FTO engine bay is comparable to the Lancer/Mirage.

 

The FTO has a 6a12 motor, much different than a G9x block. The 6a12 motor is a bit more abundant as finding SI motor in the US. Yes, this motor will fit in a 5g mirage (nearly shoe horn it from past pics on 4 and 5g mirage/lancers in the pacific rim) and most likely a better fit for modern lancer too since it has a slightly larger engine bay than a mirage.

There's a guy in Euro on our board w/ a 6a12 . . . good power for his mirage/lancer, but it was a bit nose heavy in his opinion. For a lancer which is a slightly heavier car, it might even out. Then again, replacement parts are the key issue.

 

I wonder what HP a N/A version of the EVO's 4G93 motor would put out? It has all the upgrades for to handle higher power, higher rev limit, aluminum block, higher flow ports and all the good stuff.
