Hey, My name is Jake. Some of you on here know me, I recently purchased a 1991 Galant VR4 and let me tell you its a blast. I am new to the DSM scene and am trying to learn as much as possible. So on to the car.

1991 Mitsubishi Galant VR4 # 119/2000
web cams
Forged pistons
Balance shafts removed
big 16g
ported manifold
supra fuel pump
hks intake
oil catch can

EGT, Boost, and Air/fuel Ratio Gauges

I have a set of brand new KYB AGX's that I plan on installing this winter.

Here are some pictures from the previous owner.

So the only plans I have for the car right now include...
Installing the AGX's along with a set of Ground Control coilovers
Install a boost controler(turn up boost to around 13-14psi)
Front mount intercooler, along with a BOV
Invest in DSMlink, and find a tuner
Thats about it. Any sugestions?

Yep thats me! This is the new car, a bit of a switch from hondas....but I like it a lot. Any suggestions on what to do to it?

Oil changes, check and replace all drivetrain fluids, make sure timing belt and components are in good shape. Just make sure the car is in top notch running order.

After that,.... if it were me I'd start with some suspension and brakes. I don’t like engine modding that much.

Engine Mods = side of the road waiting for flat bed.

Maybe some new wheels/tires.

Going to drive this through winter?

Maintenance is key with this car.

Suspension was the main thing I wanted to buy for this car, I would like to build it along the lines of your Dizzm V.2 (? The orange one). The KYB AGX’s will be put on over the winter, and I will be buying a set of ground control coilovers too. Not sure what I want/need for spring rates yet though.

I also want to buy some new Hawk HP+ brake pads, and possibly some new rotors depending on the condition of the current ones. Also bleed the brakes.

A set of wheels is defiantly in the future, not sure on what I want yet though. This car is hard to design to my liking. Takes a certain wheel to make it look good. I will buy cheap tires for the aftermarket wheels and buy a softer set of tires for the stock wheels.
Maybe sway bars at some point depending on how much cash I have.

The only engine modifications that are on my Must Have list.
Manual Boost Controller
Aftermarket Intercooler

Other than that I would like to keep the car pretty simple, it’s already a bit over modified for my taste engine wise.


No I will not be driving this through winter, it would be a blast, but the car is just to clean for me to risk it getting rust.

Before installing thost AGX's you may want to do some more reading on them. I know in the Honda world many like the AGX's, but in the DSM world they seem to be a cheaper struts. They'll take stock springs just fine, but they can not offer the dampening for a stiff spring. Being a bit of a rare car, I really don’t know what options are all out there. Koni's are probably on the high end and you'll pay for it too.

I would suggest getting a tuning system for it fairly early. DSMs are tuned fairly poorly from the factory and can gain a lot just from smoothing out the timing curve and pulling a bit of fuel. DSMlink is a great option but another option to consider is DSmap which is a free system which offers an incredible amount of control over the car. It does force you to switch over to speed density but my experience is that SD makes a car more fun to drive anyway. Of course if you're going to start tuning then you need a wideband which is one of the better investments I've made for my car.

As far as keeping the car reliable 4g63ts can put up with quite a bit, keep it simple with some basic fuel mods and then run the boost up to anywhere around 20psi so that you can actually use the cams and turbo that you have, neither of which are particularly happy at low boost. I am happily and reliably running 23psi on my DD with a stock 7bolt which is slightly weaker than the 6bolt motor you have and the lower compression ratio that you have will make boost even easier on your motor than mine.

Damn! Maybe I will just pair these AGX's with a set of cheaper H&R sport springs.Upgrade to something more agressive later.

As for tuning options go, I have not heard of DSmap. I have heard of Keydiver chips though. DSMlink seems awesome but pricey. I keep reading of people upgrading there MAF's what is the need for this?

The MAFs on these cars pose a restriction at any level because turbochargers are very good at pushing air but not very efficient at pulling it so anything in the intake tract before the turbocharger inlet is a restriction but this is generally considered minimal at low power levels. Usually before people consider the restriction to be a major issue they reach a point where the MAF cannot read as much air as the car is using. Specifically the 1g (same as the vr4) MAF has a very low limit which must be dealt with before more power can be made. In the case of 1g cars you can either go to a 2g MAF or you can run an evo MAF both of which can read significantly more airflow. In the case of the 1g MAF I don't remember exactly how much it reads but I think it tends to top out around 25lbs/min whereas the 2g MAF I think can read closer to 40lbs/min which is about the maximum flow of a well supported 16g run to the limits of its durability.

Speed density skips having an MAF completely and relies on a manifold absolute pressure sensor, a manifold absolute temperature sensor, the airflow characteristics of your engine, and some math to calculate airflow which can be tuned to meter an almost unlimited level of airflow.

DSmap is a fairly new tuning system but it has the same tuning abilities as DSMlink as far as manipulation of fuel and timing tables as well as injector compensation. I couldn't tell you for sure since I don't have a 1g but I don't think that it has some of the other features of DSMlink such as launch control, and single request high data rate logging. It is free through and a number of people have said that for them it is equally as nice as DSMlink.

wow, I am amazed. A honda guy that came to a dsm. Good luck with car jake!

turbo AWD ftw.

Thanks for all of the help guys. A 2G MAF is looking like a good option.

Yeah the switch from the Honda scene is kinda a big one.

I have always liked DSM's but due to there seating and dash layout I could never fit in one. The Galant is perfect for me.

I now have a solid list of things to make this car go a bit faster reliably.
1.front mount intercooler, and piping
2.Adjustable fuel pressure regulator
3. 2G MAF
4. 750cc injectors
5. Manual Boost Controller
6 Engine management DSMlink, Keydiver chip, DSmap.

After all of this it should move pretty good, and be relaible. I am really excited to start this project. Its something different, and I really like that aspect of this car.

lol sweet welcome to the world of dsms
im pretty sure i have a 2g maf somwhere il let go of cheap .its off a 2.4 diamonte or galant or somthing. i know its a dsm maf or i have a 3inch gm maf but you would need other toys to use that.

At least one honda guy has seen the light.:p Welcome to the site Jake.

Don't forget a new fuel pump and if you go big with that you'll also need an AFPR. If you go with an evo9 fuel pump or a warlboro190 you may be able to get away with the stock FPR, I happen to overrun with just an evo9 pump though so YMMV.

Oh yeah I forgot to mention the car has an upgraded Supra fuel pump.


ARP headstuds too.

Revised the list a bit.

First things that will arrive around christmas will be...
2G MAF/Intake set-up
750cc Injectors
AFPR
"stage 3" Keydiver chip

All of those besides the MAF set-up, will be bought from DSMchips.com I think. Prices there seem ok. Anyone know of cheaper?

After all of that is said and done, I will invest into...
An MBC
Front mount intercooler set-up
Lowering springs/Ground control coilovers, not sure which yet.
Wheels,tires,brakes....

That first list of things is suprisingly expensive, so the second list may take some time to get. However after the first list is all bought and installed, the car should be running 100% and be fairly quick.

Anyone know about intercoolers. Is brand name worth the extra 500$? Differences between fin and bar/plate intercoolers?
