So, I started on a bone stock lancer CC GSR 4g93t, and over the last few years have gone down the path of the standard bolt on mods that one can do on these cars, worked out from the forums here.

 

Now I never started with a plan because I was ignorant of these cars at the time, its only as I have done stuff that I have found out what you can do to them and so have only been able to work out what to do next as I have worked on the car.

 

Note that my particular plan is to keep the car looking as low key as possible, use the engine I have to extract as much reliable power as possible (so only going for 160kw atw), make it steer and stop and have some fun.

 

I am about 2/3 of the way through the mods to do this, once these are all done I have a dream to forge or convert to a 4g63, but along the way, so far, some of the things I have done have been good, some less so and so here they are (with my thoughts against each item) to look at, for people starting out and to take from them what learnings they want. Upon reflection there can't be too many of these sorts of people left, these cars are old!

 

- ECMLink V3Lite;

yes most definitely a good move; even with my limited experience I have been able to do some basic tuning to get it running well enough for a daily.

 

- Walbro 255 in tank pump

Yes and no, would not recommend a Walbro, too noisy, but definitely a required upgrade; if I had my time again I would do this, just would pick a quieter brand.

 

- Fuel pump wiring upgrade

Yes

 

- 540 cc injectors

- 609 AFM

Yes to both, lots of variety here, this is what I have chosen to support my modest power gains

 

- FMIC from an XR6

Ok mod, cheap, $80, no idea if a bigger FM would make a useful difference, but this fits behind the standard bar, is almost a direct bolt in and is OK for the modest power I am making. I suspect once one gets over 160 – 180 KW atw it will be a good idea to improve on this, but it does come from a car making 240KW at the flywheel (from memory), so good enough for starters.

 

- 3” mandrel bend turbo back exhaust

For the power I am making, and will make for the forseable future, OTT. I reckon a 2 1/2“ would have done the job and I could have saved some folding. This is one that befits from some thought.

 

- New polyurethane bushes throughout front, with castor correction and anti dive, with camber bolts as well.

Not so sure about this one. By the time I'd bought the front bushes, the camber bolts and had them all fitted, it would not have cost much more to get a K-MAC Suspension Camber and Caster adjuster kit. True the new bushes have tightened up the front end, and the original bushes were 20 years old, so really can't decide if this was the right thing to do. Certainly some careful thought required here as well.

 

- Front strut brace

Christmas present, so not complaining! When I fitted it it seemed to make a difference, as measured by the backside meter; I would do this again.

 

- EVO 1 enki wheels and EVO1 front brakes

Yes, Yes, Yes

 

- whiteline 20mm rear sway bar

Yes

 

- All rear suspension bushes replaced with SuperPro polyurethane items

Yes, if a weekend fun track car

No I would not do this again, as I drive the this car 20K kms a year, ride is too harsh, absolutely love it on smooth roads, anything less than that though, and it crashes, bangs and rides like it is on wagon wheels.

I think you can get rubber bushes stiffer than stock, which would be ok for me.

My advice (which is worth what you are paying for it), is if you do lots of road miles, stay with rubber bushes in the rear.

 

- Short shifter

Yes

 

- Replace all gear linkage bushes in cabin and at gearbox

Yes

 

- EVO1 seats

Yes, but, maybe look at later EVO model seats. The EVO1 seats are so much better than stock but still not good enough (which surprised me) when you start to throw it around.

 

- New carpet from Knox auto carpets

Yes

 

Still have to fit WB, bigger turbo, boost controller, and get a proper tune. If I have any useful thoughts on any of these I will add another post but sadly I don't get seem to get to new mods as quick as I would like, so it may be a while.

 

Hope this gives anyone interested some useful info.

I haven't got a gsr but this is a great start thread for any of us that may be thinking of modding with little experience Dave.
Best of luck with the remainder of your build buddy.
Oh, and yes, the BA xr6 turbo had 240kw at the flywheel and around 190kw atw. If you are really keen I have a magazine somewhere where they put a stock on the dyno if you really wanted to know atw figure.

[leadfoot]

you've preety much gone as far as you can on a standard block from here you have to choose to commit to the 1.8l or go to the 2l.

if you commit to the 1.8l prepare to have all the naysayers come at you. you can make some very healthy power from the 1.8l with the right parts will you make as much power as the 2l possible but will you get it as easily HELL NO.

 

currently my 1.8l makes 171 AWKW. and is barely even a 4g93 any more i call it the 4g93MT
it has
forged rods and pistons

1000cc injectors

mivec head from the 1.6l (purely to get a high lift duration cam while retaining a stock and factory esk idle)

td05 16g (never thought id be saying this but i've hit it's limit)

fmic

haltech ps1000

i've probably pushed factory bolt on parts as far as they can go and i'm happy with it for now. i do intend on going e85 and will likely need a bigger turbo

[BYBY5L]

Kyle, How many psi are you pushing?

[leadfoot]

20psi

[BYBY5L]

True, Isnt the 16g good to 25 odd psi? Or is that more with the 2L?

[Nmko]

When i spoke to Chris at Meek last he told me the 16g pretty much maxes out at 20 psi and basically not to run anymore on a forged 93t...

[VIN18M]

Is that because of the motor or the turbo?

[Nmko]

Im not sure, at the time he was kind of rushed so i didn't push for more info.

[leadfoot]

just dosn't flow enough over that any more and you just pumping out hot air

[VIN18M]

I just thought it was weird if Chris said not to run more than 20psi through a forged motor. If he was making reference to the turbo I can understand his reasons.

[leadfoot]

really all depends on how the motor is built.

many thing come into play ring gaps head gasket types of head bolts/studs (which woul likely be the first thing to fail over 20-25psi in a 4g93) they just don't have the heft of say a 6 bolt 4g63. etc my goals were 200 awkw from this motor i might get that on this turbo with e85 maybe not i have my reason for trying to stick with factory based stuff.

Thanks WK!

 

Re that magazine info of stock xr6 dyno figures, if it is handy that would be great! Help me get a feel for 2wd powertrain losses, always interested in power train losses and not easy to come by. Plus I've always liked xr6 turbos.

Interesting nugget of info, one to add the list to help decide which way to go in the future, as I can't decide whether to forge or convert because I can convince myself either way. Not that that is an urgent decision, some years off unfortunately.

25% for 2wd, 33% for awd, add another 10% for auto. Roughly
and 3kw is 4hp

Dependant on dyno, but, good enough jack.

Yeah, thats what I have tended to work with, since it was suggested from previous posts, but  I've always wondered as it makes my GSR power levels almost EVO1! 131 kw atw is 174 kw at the flywheel, not much short  of an EVO1 (a quick google says 182kw), which seems pretty cool but I'm not convinced, I can't believe I'm that close. That's why I am interested in dyno figures for stock vehicles, even if not for a lancer EVO or 4wd. Getting that info would allow one to compare against the estimated powertrain losses to see if they were ballpark.

 

Probably a bit obsessive but thats just me!

[jack be nimble]

Just compare you terminal speed on a 1/4 mile. Plenty of 1/4 mile info for std cars.

[White Knight]

+1^
Different dynos/different days can throw up a lot of differences between dyno results. The dyno that I use had a 39'/. Drivetrain loss on a stock wrx.... But I admit to being totally engrossed by dynos in the past as well.
I am still searching for that magazine for the xr6 turbo results. I'll post when I find it. I have thousands of magazines. They USD to be chronologically and categorically sorted but a housework obsessed missus and messy kids kinda ruin that from time to time, lol.

[White Knight]

BTW, what turbo does the stock GSR run? Just curious.
