#1: 4g63t v.s. 6a13tt? Author: Grip,

Thinking about doing a vr4 conversion on my galant vrg, however it was suggested that I use a 4g63t instead of the 6a13dett. I want to know what are the advantages and disadvantages to both swaps also the costs associated with them.

main disadvantage is the the price............you can get 2 6A13tt complete in front cuts for the price of one 4G63T on the ground and you still need rear suspension parts from a VR4.

So which engine is better, while it is true that the 4G63T has a lot more aftermarket parts letting you push to 500hp or more fairly easily, nothing like that exists for the 6A13. For most folks 280-350hp range is enough for some fun driving so I don't see a reason to even consider the 4G63T. A full exhaust including downpipes and increased boost will see you to over 320hp very easily, add an intercooler and a fuel controller and you'll be at 340-350hp.

The V6 is an amazingly smooth engine with no harsh explosive power and vibrations at any point in the rev range and it loves being anywhere between 1500rpm and 7000rpm with virtually no turbo lag at all.

Anybody here who has ever got a ride in an EVO knows that below 3000rpm they feel like a normal 4G93 1.8L 4 cylinder. But from 3500 to 7000rpm they explode to life and feel just like a 6A13TT, not some super special amazing engine ent?

The EVO 9 and X are rated at about 215kw and 400nm of torque, a 6A13TT will get over that amount just by increasing boost to 12-14psi with a cheap manual boost controller. Without changing the turbo a 4G63T is limited to about the same sort of power levels as a VR4.

As far as I can see the only advantage of going with a 4G63 is that you can buy manifolds and turbos that will let you get to 500hp or more straight off the shelf. However that will cost most folks an arm an a leg to buy an thats after paying for the EVO engine with your 1st born and a left kidney Shocked

So far the only people who have put 4G63's into 8G's are the Americans and thats because they cant find 6A13TT.

Engine Calculator v 1.2 ......>>>>> http://tpizza.110mb.com/ecv1_2.htm
This page will calculate lots of values for an engine configuration that you enter. This is useful for determining the size of turbos, injectors, exhaust piping, intercooler piping, etc. It also gives you an idea of what affect better heads (better Volumetric Effiency), higher boost pressure and other factors have on horse power output. Values by default are for 6a13 2.5L V6 24V DOHC Engine. 8G Mitsubishi Legnum VR-4(ec5w) or Galant VR-4(ec5a).

economy and speed.........is like oil an water.
The VR-4 was fitted with a V6TT because the engineers figured out the maths

A heavy Galant need more torque to move. Laughing

is the hyundai tiburon using a stroked 2.7l 6A13 and calling it V6 Delta ?
I say it is because it is an aluminum block not a cast iron like the 6G72

http://www.korea-racers.de/elantra/v6swap/index_en.html

i was poking around in the overseas hyundai forums since a fellow tuner here wanted to swap a 6A13TT in a '96 Elantra frame. But most of the folks over seas who have done it used the Tiburon motor. It looks like it is using 1995 mitsu 6a12 technology with no coil packs

Bolt for bolt, it will be easier to install the VR4 system 6A13TT. but whether you look at it one way or the other, it's expensive. Don't discount the 63T because of it's price though... in the longer run, it may actually cost you less to run.

And the main reason is accessibility to parts... OEM or aftermarket. You will faster get parts for a 63T than the V6 and quite possibly much cheaper too. The engine is capable of making loads of power with the right tuning/ build.

But if it's bolt for bolt and you can source your parts with a reasonable price, the 6A13 is a great engine.
