Well truthfully, not much. The words "Modify" and "not compromising gas"
can't be in the same line.

Basic intake with better filter to flow air in and also a better exhaust including an extractor manifold setup will give you minor gains... but it may be more cost effective to purchase a similar engine in EFI trim, such as the 4G91 DOHC. That engine is roughly 40hp more than what you carrying now...

Or you can use the 4G(92) SOHC 1.6 or (93) SOHC 1.8. lil more torque in the higher displacement engines.

And same priciple as the 4g15... intake and exhaust. would make a difference...

History of My Libero:

bought it with a 4G93 n/a 1800 SOHC - transmission
change tranny 4G93 n/a 1800 SOHC - 5FD Gearbox
then to 4G93 n/a head with 4G93T block with turbo, intercooler etc.
then to Full 4G93T 1800 GSR turbo with FWD gearbox.
now back to 4G93 n/a - with gearbox.

My opinion is that you should have a budget plan. There are many people on this forum that can help you with advise and also supply parts, engines etc. But it will all boil down to how much you are willing to spend...... and keep spending as your maintenance cost will also go up.

Just off the topic, but how did the 93T head on the SOHC block handle?

MISHI, it was a 4g93 n/a head on a 4g93T block.

Had alot of fuel problems. everything else worked great. I didn't have the 4G93T ECU at the time....hence the SOHC head with n/a ECU.

With turbo injectors, too much fuel at idle and with n/a injectors, not enough fuel when accelerating. I didn't have the money to buy a fuel management system, so I used an extra injector on the intake piping, powered by a pressure switch. Adjusting the timing of the pressure switch was a beyotch, BUT when it worked ..... IT WORKED !!!!!.

ok ok urgent and i back wit dis thread in bout 3 mnths time i looking to change the libero engine.....its a 4g15 carb so i want to change it to the injected engine....i saw the engines posted above and they looked good...but i wanna kno which one is perfect with the libero so dat i dont have much other modifications to do like transmission e.t.c. i also looked online (wikipedia mitsu engines) and saw a 4g15T engine wat bout dat type? anyting between 1.6 up to 2.0 SOHC OR DOHC (wit known current prices) suggestions is welcomed? NO GDI THOUGH....LOL...dem is too much trouble and pricey 4 parts!

some 1 reply to me as i wanna know for tru wat to do!!!!!!!

also can anyone direct me to what type and where (PRICES) i can obtain HID or PROJECTORS headlights that can fit smotthly onto the libero......

A solid body kit......

A tachometer or instrument panel that has a RPM guage because my panel dont have a Rpm guage only gas, speedometer and other normal configurations. also needs one that will fit easy into the original libero dashboard

also where can i get a gas guage card for the libero and at what price???

^^LOL....like u need a new car!
1st tng seeing that ur a libero why dont u geh ah evo3/gsr libero front cut & jus puh n.It ha one in freeport selln for the longest while probly think it still they.

2ndly If the ck2 head lights are the same as the libero u cud geh a set of clear projectors & puh it in.Price of projectors $2800.00 with harness & everytng.

If you want to go turbo, the 4G93T Avg $ 8,000 or 4G63T ( Evo 1 - 3 ) $ 15,000.

If not turbo : 4g93 SOHC. This works great on the libero and will only cost about $ 4500.

Give me a call 798-6844 I can link you up with any one of these engines.

so shaka the 4g93 sohc or i seein they have a dohc version also......

so will it go on bolt 4 bolt?? and wats the other mods that may have to be done with the engine.......

but i knda skeptical on that engine as its GDI.....that mite be sum worries...how it worked 4 u both power and economically wise????

wat about the 4G18??????

4G18 WASTE OF TIME...THAT HA CVT TRANNY.

This is not the GDI version. I'll take some pics of mine in the libero and post it.

1.8 L engine (4G93 SOHC - 86 kW) CB model.

ok i still thinking bout the engine but if i wanna keep the old 1 and modify it i wanna kno how much will extractors, a k&n short ram style filter and a free flow muffler will set me back and where can i get all done in a day???

You need to compare the cost of upgrading your engine vs changing to a bigger one. If it will cost cheaper to upgrade your engine and get the same or more hp than the 4g93 or any similar engine then you can go that way. just my opinion !!

The SOHC 4G15 displaces 1.5 L (1468 cc) with a bore and stroke of 75.5 mm x 82.0mm. It has approximately 92 hp (69 kW).

4G93 16-valve SOHC 1.8 liter specs.
Bore x Stroke: 81.0 x 89.0Piston Displacement: 1834ccCompression Ratio: 9.5:1ECI-Multi(Electronically Controlled Multi-point Fuel Injection)
Max Power: 86kW @ 5500rpm
Max Torque: 161Nm @ 4500rpm
Horse power: 113 Torque

This is a 4g93 in my libero.

^^Shaka, which car you geh dat 493 out of??cuz to me if it came out of a galant wouldn't the tranny & air filter be on the left hand side of the car??

They come original on these Liberos. I don't know what else, but they came in the CB version. I swapped with a 4g93T for a while, and then back to this 4g93 with FWD gearbox.

Found this:

In 1993, the Lancer wagon, named the Libero in Japan, was launched. An electric version was also released named the Libero EV that ran on NiCd batterys[1]. A V6 variant was also introduced with only 1.6 L, making it the smallest mass-produced V6. The high-performance, turbocharged GSR version formed the basis of the contemporary Lancer Evolution (or 'Lancer Evo') from September 1993, using the drivetrain of the successful Galant VR-4 rally car.

Model and trim levels:

* GL - 2-door coupe, 4-door sedan and station wagon. Powered by a 1.5 L engine (67 kW)
* GLXi - 2-door coupe, 4-door sedan and wagon. Powered by a 1.8 L engine (4G93 SOHC - 86 kW) (sold from new with 1.8 instead of 1.6 variant, due to Australia's poor quality "91 octane" fuel)
* Executive - 4-door sedan and wagon. Powered by a 1.8 L engine (4G93 SOHC - 86 kW)
* GSR - 4-door sedan. Powered by a turbocharged 1.8 L engine (4G93t DOHC - 141 kW)

word!

good stuff there!

Shaka, i bought a CB lancer could u tell me about ur specs, wanna do something with it, a little sporty, faster

Now Shaka tell me if taking out the catalyic converter is a good idea and wat effect will it have on the car overall. also i willing to spend about $650 on a free flow muffler (well the shiny barrel tingy or watever they call it) wat will be the best type and wat to expect wen in put on the libero...speed gain/noise wise!!!!! (thinking bout doin the piping and headers also "thinking" bout it...lol....wat effect or gains will that give on the 4g15)
