What engine should I go for?

[spetz]

So I have 3 engine choices. It's for a 2001 Coupe Lancer running 6A12 MIVEC

Choice 1 (this is what the initial plan was and everything has been done but engine isn't assembled yet)
Fully rebuilt, balanced, ported heads, raised CR, extractors, cat, exhaust, ported intake, 5mm oversize TB, piggyback ECU, cam gears
Stock cams
Mated to a DC5R gearbox
Also, a hell of a lot of other cash to spend elsewhere such as stereo, retrim and respray (suspension, brakes, bodykit, wheels, Recaros etc have been done)
Choice 2
Use this engine but use 12.5:1 CR forged CP Pistons, Argo econo rods with ARP2000 bolts, cryo crank, valve springs, port heads more, port heads more, have some cams with peak power around 9500rpm, valve springs, Haltech standalone ECU, twin TB setup or 6 pack TB setup, and other mods as per Choice 1 including DC5R box

Choice 3

Pretty much that beast but 6 pack TB setup and some wilder cams than supplied. Note price for that is around 13K + shipping
Standard FTO box remained with cryo gears and replace 1st gear to a much taller gear to make it usable and so that it shifts into MIVEC when upped into 2nd

Choice 4
Try and custom make the engine in Choice 3 and hope it turns out cheaper
Again with the 5speed FTO box

FTO box has a Version R LSD as well

And what do people think my car will do down the track with each engine?
To give you an idea my car with extractors, exhaust, cat and FPR on street tyres would do 14.2 with a 12 year old never rebuilt engine at 1120kg not including driver

choice 2.
mid 13's i'd say.

elighten me though, evo motors, they practically botl straight up?
if so, why not use a evo motor, or you wanna keep it na?

[spetz]

Yeah Evo motor is an easy swap
In fact when I went to drop my car off for the conversion both engines were in front of me and I had to choose choice A or choice B
Unfortunately my idiot dipshit of a friend was a hardcore Honda fan and convinced me of going the MIVEC.
Now, I love NA and I do want a very fast NA car. But more importantly I made this choice and I am sticking by it.


Can I ask, why choice 2?
The 500cc extra would make a huge torque difference. And if you are thinking from a gearbox perspective, a DC5R box can still be bolted I just thought it would be pointless having shorter gears in a car which should be making more power and possibly torque than a 3.0 NSX engine

[spetz]

Also,
I think choice 1 should do mid 13s
Considering the mods, fresh engine and closer gearbox compared to the otherwise standard 14.2
I think choice 2 should be closer to low 13s depending on traction and the 2.5 should be 12s if not 11s on a stripped prepped car with full slicks
Of course I could be wrong and this is speculation only

[spetz]

Edit: I meant Crower Econo rods not Argo

[Q_ball]

Not being a smart ass, but maybe try asking a Mitsu forum or an Evo forum?
Might have a bit more info for you than a Honda one.

[spetz]

I value the opinions of members here
Also, I don't think Mitsubishi forums would give me a good enough answer. Most people would just say "2.5 MIVEC"

[Slow96GSR]

I would toss in a Chevy 350 and twin turbo it, but that's me! As for what you posted I like a little of all. But I haven't done a lot of mitsu's myself so I don't really know what works great in them. Figure out what you want to do all around and see what you have to spend. Then go for what you can get. Doing the internals now would be the best as the bolt ons are easy to install anytime. Just my thoughts.

[xtercii]

Yeah not trying to be rude but I do find you asking a lot of Mitsubishi questions on this forum, but do you realise most people here are into Hondas' and probably don't have too much knowledge about mitsus, and even if they do, the lack of interest could mean they wont be bothered answering your questions.

[nigs]

4G63 doesn't fit in your car?

[spetz]

Sorry guys but it is MIVEC and most people here are into NA
Most Mitsi people are into turbo

And yeah 4G63 fits but it's too late

The cheapest solution for me is choice 1 as it's all already done. Just another 2ish K I owe for the gearbox
Then, choice 2 allows me to go further with my engine at a later stage if I want/need to

But choice 3 and 4 I need the cash straight up, but at the same time will offer me huge amounts of power and torque... but the money

[nigs]

If you're chasing power, 4G63 or 4G93 is the most obvious answer.
Unless you got money comming out you bumhole and you're trying to prove a point with MIVIC/NA then go for it.
