6G72TT swap but using parts from 6A13TT

[hayase]

Hello, newbie here and need question related to 6G72TT and 6A13TT (VR-4)

I make this threads to discuss my problems while killing time waiting for anyone that sell Hi Vis Dash (260 km/h Speedometer) and MMCS Facelift from VR-4 Facelift

here's my thread, some of u that want to sell the items above can check my thread :
My Thread (http://www.clubvr4.com/forum/forumdisplay.php?f=192)

I'm newcomer here and I live at Jakarta, Indonesia, any1 know Indonesia ? It's famous for Bali's Island. My country located between Singapore and above Australia

I'm the owner of Mitsubishi Galant 8G 2.5 V6-24 (6A13 SOHC) M/T year 2000 and I decided to do swap engine, and 1st though I gonna choose 6A13TT (VR-4) for my choice. However I do realize I need more if I want to fight Ferraris or Lamborghini (quite a big talk huh !?)

so I gamble all of it on 6G72TT (from GTO not 3000 GT) for my 8G. Well I do know that Galant has 3.0 SOHC 6G72 but I'm not sure it'll be the same as plug and play just like 6A13 and 6A13TT. I mean if there's some1 already succeed put 3.5 V6-24 DOHC 6G74 to his 8G which is way bigger than 6G72TT, then It's should be fine right

I plan to use most part from 6A13TT (VR-4) to combine it with my 6G72TT engine especially gearbox (yes it's for my future 260 km/h hi vis dash :D). Do any1 have suggestion to help me succed this swap ? :D

sorry if my english kinda sucks there, I mean English is not our language after-all

[hayase]

mechanic or some1 that know well about 6A13TT will be appreciated

When you say from a GTO not a 3000GT can you explain why, and what difference you are saying there is between them. In the UK we have had the 3000GT released to the market with TD04 13g turbos, whereas the JDM market equivalent GTO had only 9b's, so its actualy seen as an upgrade to use the 3000GT turbos on a GTO.

well my galant is Right Handed so I'm using from GTO instead of 3000GT. Unless My Galant is Left-Handed, sides to find 6G72TT from 3000GT is kinda hard at South East Asia's region

yeah I only got 9b's for my turbo, shame on me BOHOOOO, gonna saves lot of bucks for Garrets but I won't talk bout it now, not when this swap is still unfinished

but 6A13TT is not half-bad too and direct fit plug and play really help us, vr-4 owner wannabe

I was under the impression that the 6G72 and the 6A13 work as mirror images of each other, meaning that putting a gearbox from a 6A13 on a 6G72 would effectively give you lots of reverse gears and one forwards?

LOL, i think it's the same unless I'm using 6G72TT from 3000GT which leave me no choice but to use 6G72TT gearbox

[Nick Mann]

Are the engines opposite ways round in the GTO and 3000GT?

[hayase]

i think yes since 3000gt mostly left handed, honestly i'm not too sure if my project will be successful, guess what i can do is only trust the mechanic

btw i know it's out of topic, but seems no1 sell mmcs or hi vis dash 260 km/h huh ?

[Kenneth]

The engine doesn't have to rotate the other way. it looks like the cam belt tensioner is on the same side as the 6a13 so it probably rotates the same way.

IIRC it is the gearbox and transfer case arrangement which determined that they had to swap the engine orientation. Supposedly the later arrangement is lighter and a bit more efficient or some such.

All the GTO's and 3000GT had the engines in the same orientation, so its my impresssion that they all rotate that way, which unless Ben can set me wrong (as he is the man in the know of the GTO, would rotate the other way. Also you would be more than likely be into bellhousing fabribaction as im not convinced they would just mate up

[scott.mohekey]

I THINK, the GTO/3000GT is the same as the 7G Galant in that the engine spins the same way as the 8G 6A13, but the gearbox has an extra shaft, reversing the output to match the orientation. OR, its the 8G 6A13 that has the extra shaft. One or the other.

[--hoff]

Why would you want to mate 6g72 trans with 6a13tt engine? If it just to get 260km/h than it will be pointless. Even you are on the track you will never reach that speed. Unless you driving on nurbrugring or TOP GEAR track where they do their speed test.

[scott.mohekey]

I think you misunderstand. He wants to put the 6g72tt into his 8g galant.

[Phoenix]

Are the engines opposite ways round in the GTO and 3000GT?

Yes, they do sit opposite ways round in the engine bays.

[Eurospec]

Gareth and scott are quite correct. All 6g72s are the opposite way around to the 6A13. They share their orientaion with the 6A12 from the 7G.

That will be a pretty involved swap. There is a large degree of similarity between a 6G72 and a 6G74, so there will be clues by looking at the 74 conversion.

Cheers,

Ben.

[bradc]

All 6G72TT's are yes, but there were 6G72, 74 and 75's around the 'right way' for us, including the USDM 8G 6G72's

[scott.mohekey]

I know of someone that has put a 6A13TT from an 8G into a 7G in the same orientation as the original 6A12TT, using the 7G's transmission.

As brad has said, there are 6Gs in the same orientation as the 6A13TT in the 8g, but as far as I'm aware, they're only FWDs. However it might be worth looking into whether the bell housing from one of these same orientation 6Gs will bolt onto the 4WD transmission from the 6A13TT.

[bradc]

There were 6G72 4wd Magna's, or were those 6G74's?

[hayase]

i think it's 3.0 SOHC 6G72 not 6G72TT

btw bradc, please help me bohooo (u know what i mean)

[scott.mohekey]

According to wikipedia, their was an AWD model from 2002, but only in auto. No exact numbers are given, but it sounds like there wasn't a great deal of them made either.

[bradc]

Yep, only auto magna 4wd's

[Turbo_Steve]

If you want to race Ferrari's and lamboughinis you're going to need a LOT more than an 8G galant with an engine swap: you're giving away over 500Kgs in weight and around 150-200bhp on a 6G72TT.

Given how much it's going to cost to do the conversion, I suspect it would be easier and cheaper to fit a 6A13TT into your car with a pair of TD05s on it and all the usual stuff (ECU, fuel etc).

The hardest part will probably be finding that 6a13tt engine in the first place!

Taking the 6a13tt to 500bhp in standard trim is not something that a lot of people have done in CVR4, but it would appear to be possible without forged internals.

If you wanted to save money, you could use the 6a13tt block with a single, large turbo. Again, if it's cheap to get work done out there, having someone make you up some pipes is probably a much simpler (and cheaper) job than changing engines.

OR

Have you considered NOS?

[hayase]

wow thx guys for the idea

My mechanic just call me that he gonna use gearbox transmission from 6A13TT, same as what scott.mohekey said (6A13TT at 7G)

but I'm not too sure myself if it's gonna work since 6A13TT and 6G72TT has different ratio

actually in my country, 6A13TT is not a rare engine, most of galant owners who've done engine swap use 6A13TT, while few using 4G63T, therefore I'm the only 1 using 6G72TT

oh yes, there're few VR-4 (including from engine swap) that reach 500hp in my place and all of them are not using stock internal anymore

suprisingly weird, parts for 4G63T and 6A13TT is MUCH MUCH more expensive rather performance parts (including aftermarket) for 6G72TT at my country

Nah won't use NOS

Can you post a real data such dyno sheet, which type of dyno used, and car spec to back up your statement? Even ZENTAC is trying really hard to get pass that 500hp figure. He already installed forged internal and it's not even a AWD setup.

Due to high population and the fact 4g63T is a 4 cyl engine, performance parts for 4g63T are relatively cheaper and and easy to get compare to 6a13TT and 6G72TT.

You definately dont know what your talking about bro.....

Yeah that's what I said, there're few vr-4 owner that reach it but of course it's not internal stock anymore (that's what wrote right).

sorry what I mean is 500 hp on engine / crank, so it's not that powerful if it's on wheel
not to mention it's using racing gas. I guess if u using whp and 95 octane gas, it's prob just 400++ hp or even less since it's awd

that's why I want to give it a try using 6G72TT, to see how much it can go

well in my country, not only due to high population but also on high demand that 4G63T and 6A13TT are more expensive than 6G72TT. Guess what I bought 6G72TT engine for 2000 us$ while even the cheapest 4G63T and 6A13TT from my country is around 2500 us$ (not halfcut). Not to mention the engine 6A13TT is direct fit for our 8G so it's a quick way to gain 280 hp for us. So yeah it's about demand, that's how it works at my place, kinda fugly huh ?

if u want, u can buy 6A13TT from our country, most of us get it from malaysia or singapore though. But if you're at OZ or NZ, u can get 6A13TT easily from Singapore too I think. Especially Singapore, they got lot of halfcut for sale there. Most Indonesian reseller get it at junkyard located at Woodland Industrial Park, Singapore

but I do heard 6A13TT is very rare ouside asia's region, and aftermarkert parts for 6A13TT is not too many compare to 4G63T, need to be confirmed 1st

[Turbo_Steve]

Aftermarket parts aren't RARE per se, but they are a lot loss common. You will pay more for them.

really ? at our place it's hard to seek aftermarkert parts for 6A13TT

btw I've checked ebay and other side other than Asia, seems 6A13TT is kinda harder to get for outside Asia region compare to 6G72TT

btw thx for your suggestion steve, just pray it's gonna successful
