Opinions Wanted

[Dracas]

Trying to road-map the modifications I'm going to have done to my 95 Galant S, and wanted some opinions, as well as mechanical feedback to make sure this is all sound before I start saving to have everything done.

It'll be awhile, so I have plenty of time to make adjustments. The vehicle is a 7th Generation 1995 Galant S 4-Spd Automatic. I'm not sure I want to do the modifications on this model in particular due to the fact its an automatic, but I do intend to use a 7th Gen Galant as my target vehicle. Chances are I'll run this by a friend of mine whose a hardcore mechanic as well, my major concern will be all the power-plant interchange and block-swapping.

I also intend to make various changes to the trim designs and possibly rebuild the rear end to accept a specific set of Altezza's I found. At its heart this car will still be a Galant, but overall at its core and at its body, I wanted to redesign how this thing looks and performs, mainly because I know the potential that Mitsubishi gave us with these vehicles.

One day this car will earn the "Type-S" Emblem I'm slapping on the back of it, because the lonely "S" in the rear corner just isn't enough

Opinions wanted, let me know if this is all mechanically sound, or you can recommend some better parts in there, thanx

I just hope your pockets are much deeper than mine. Oh, and plan on setting aside another $1500 for a new transmission. With the power you look to be persuing the stock tranny is not going to survive. I'd lean toward a 5 speed swap looking at the set up you're shooting for. But a Level10 unit would work well too. Also, if you're going for a hybrid '64/'63 (I.E. '64 2.4L block, '63 DOHC head) you don't need a new block, the DOHC and SOHC '64s use exactly the same block. As for new pistons, you're looking at between $400-$600 depending on what exactly you want. You have to get them custom made, thus the expense. And if you're going to all that trouble, you may just want to build up the entire bottom end. It won't need much as Mitsubishi bottom ends are nigh indestructible. And a final point, if you want a turbo, cancel the order on the headers. Headers are a N/A only mod. And while I'm at it, do you live in Cali? If not, screw the pre cat. Just get the one big one.

yeah, what Kain said.

If you get the custom pistons for the 64 block and 63 head (no stock pistons work) then you'll need to get the block bored and honed to make everything work.

dohc swap along should run you about 500 including a timing belt, head, and 94 Galant GS dohc ECU. Then you'll want AEM cam gears and a lot more fun stuff.

The turbo parts if all are used should gost around 1200.

Then you'll want a better transmission too.

Kain: Does that mean I can swap my SOHC for a DOHC with relative ease? What all would i have to do?

Parts List for DOHC head swap

1) DOHC head(filling 5 water holes on the block) 1g is better
2) galant gs timing belt
3) head gasket
4) cam gears
5) harness
6) ECU
7) if possible low comp pistons



14b TURBO

1) Mitsubishi 14b Turbo
2) intake manifold (1g is better)
3) exhaust manifold (2g is better)
4) 02 housing
5) resistor pack
6) 450cc injectors
7) safc
8) boost controller
9) bov
10) i/c piping
11) i/c
12) downpipe
13) turbo inlet pipe
14) oil lines
15) water lines

thats estimate parts for turbo and/or dohc head swap

IMO, for that amount of work and money it would be more lucritive to just do a full swap. The 4G63T is nice or if you can get your hands on the infamous 6a12TT that would be the shizznit!! :twisted:

It would take a lot of dough, time, and modifiactions but no more than what you are looking at now.

A GS-T M/T would also be a good choice for the tranny I'm thinkin'

[Dracas]

The point of Hybridding the 4g64/4g63 was to get a better compression sample (Compliments of the 46g4) and a turbo I thought?

Hmm, I may be pretty much redesigning the engine anyhow, however, will the 6a12TT engine even fit in the space in the front of a galant to begin with? Theres a limit to whats considered "Modifying" and whats called "Re-engineer" I don't really have the time of facilities to re-engineer a powerplant for this car, not to mention I lack the resources for that, as it stands right now, this is a $5000 or so project

But if its possible to do without Re-engineering, I'm game

[2True]

The 6a12TT will bolt right up (relatively speaking) with ECU and wire harness. It is for the J-Spec 7g but It will fit in the USDM I'm thinkin'.

Here is the 6a12TT in a 7g from the PI. Thanks to VR6 for the pic

I couldn't find the specs on it but from what I see.. V6 (Twin?) Turbo. And obviously you should recognize the car it's in.

Importing one will be your largest obstical...

[seth98esT]

heres a 4g63 dohc head from a talon tsi for $150...im thinking a full dohc head swap will be est $500...and a 14b turbo swap will run around $1000-1500 depending on how you do it
