There aren't any labels on that Tb.. I think it would be a better way to search for TB with the same sensor connectors, Could you tell what label should be on 4g37 Tb -Mikuni or Mitsubishi to bolt it without any difficulties?

Going down to check my TB right now .....
"Made in Korea"
My old (1.5L) one said Mikuni I believe. The one I got came from a Hyundai Sonata here in North America. The labelling in the end may mean nothing depending upon where the parts were sourced to provide assembly for cars headed to certain regions of the world.

Best bet is to take your old tb or find an old one at the yard and compare to a Sonata TB or similar 4g37 SOHC model engine and find the one you need; the connectors will be the same but you may or may not find the TPS sensor in the same twisted position, I had to remove part of my old TPS tang? (metal rod) that operated or provided the twisting force against the sensor an swap it over. That's about it except for swapping the full (known good sensor) ISC and zero throttle sensor bracket with my good sensors attached. Your ideal setup will be to just plug one or two extra vaccuum lines top and bottom and pretty much plug and play. Make sure to get the bigger gasket ie. the one for a 1.8L SOHC engine and if you have the time and know how- definitely port match the intake to the TB.

"made in korea" is what ive seen on all the Hyundai made Mitsu parts.

I have a 4g15; just what are the bennefits to putting a 5mm bigger throttle body on it?

better throttle response, a slight increase in top-end performance, and improved acceleration. On a 12v engine, your probally talking a couple hp improvement without other mods. On the 8v engine, maybe 1 hp since the porting is so small that volumetric efficiency isnt improved very much. The 12v engine has much larger porting while using the same throttlebody.
Think of four-barrel carb vs two-barrel carb

Thanks for the quick response. I'm looking into it, so if you could help...

1. Where could I pick one up? (4g67 TB, that is)
2. How is installation?

Thanks,
JD

any junker that has a 1.8L eclipse would have it :-p
and it's 4 bolts in, out and boom you are done
err... i forgot about the coolant lines that connect to the TB, so 4 bolts, and 2 clips holding on the 2 lines on the TB and boom you are done

dont forget to port the intake too, or you'll get minimal benefit.

Thanks fellas.

PS - How do you port your intake?

it's still awesome without a ported intake, I have a ported intake, which is going on today, so i'll tell ya how much more it kicks ass

Enough to break the wheel loose on a hot day that wouldn't have happened before. You can get to the point of burning the stock clutch slightly, well enough to smell that you didn't let out on the clutch fast enough from a STOP-1-2 Shift.
The system leans out slightly as more air, both metered and unmetered, is being drawn in under all cirumstances but overall I have found that idle stabilizes just as quick when the ECU learns again due to battery removal, accelerating is better and bypassing the coolant lines that go to the TB can help ward off ping as long as the engine is kept moving and the air/engine don't become heat saturated too much. Once the motor is baking at stop lights, the motor likes to ping when part throttle until things cool abit in the air tract and further down the chain. I surmise a thermstat that opens a little sooner may a help here but haven't bothered and now things are cooling down again. I have tuned using cheap 87 octane and it doesn't do anything for performance but the motor really does love higher octane with the compression we are running. Don't bump your timing or play with the timing cam trick until you have things settled and figure out your aren't running badly because you can compound problems very quickly when tuning; the only reason I am leary of tuning the only car I can afford to drive of the two I own!
It might be a time to think about an Octane switch soon .... hmmm.

Hi there!

U guys in the US sure do have a lot of 2 door Lancers ( U call them Colts, I think).

I have a 5 door hatch CA 1990 Lancer with 4G15 8v. Very rare to find a 2 door in Land of Oz.

I have been told that one cannot swap the T/B on a 4G15 8v coz it will stuff up the ISC motor. I was told not to even think about boring it out

Anyone got any "juice" on this??

Flying Eagle, better octane fuel is definately reccomended if you are modding. Especially when you alter mechanical timing events. Retarding cam timing slightly raises compression levels as does advancing ignition timing. As i'm sure you realize at this point, all this requires higher octane due knock occuring easier. With my mods i can run 89 octane at stock ignition timing with 4-1/5* of cam retard. With 7* ignition advance, i require 91 octane-which is where my current setup is.
