so getting under the car to take some bolts off is what is recomended?...

 

baha- i thought that we were sposed to use the 1g throttle body(eclipse turbo)?...

 

unless you like crushing your hand between the runners I even go so far as to remove my downpipe most times just because it gives me more room to work under there.

 

also if anyone want to help me dyno my car...i will do a before and after IM install.....since i only have a few mods this will give you a better idea of what the gains of IM are....so let me know if you guys can help pm me or soemething....sorry but i would love to pay for the dyno but that extra $120 i kinda need...

 

Yes, there is a flurry of info. I'll have to clear this up a bit.

TB
1g
90-91 = a no go - different ISC, TPS, and vac line plumbing
92-94 whether turbo G63 or not will be 60mm.
Don't get anything from the 4g37 motor.

2g
95-99 = G63T = 52mm
Never get the 420A TB - vastly different stuff. I rarely look at them.
(correction)

3g eclipse
TB has the throttle cable facing the firewall and is 52mm according to the 3gClub guys.

 

here's the problem. i need to make an adapter harness from the stock wiring harness to the 1g sensor. not only are the plugs different between the 1g tps and lancer, but the tps themselves are different. once i took off both tps sensors, i was like wtf?

i just got home from radio shack and gonna try and make an adapter harness. the lancer does not require a throttle closed sensor so i'm hoping that i just have to make the 3 connections from the 1g tps. looking at wiring diagrams, this looks very possible.

 

haha neener neener

 

I just remembered that I have a spare IM sitting in my closet. Anyone wants it , please PM me. Probably like 50 bucks shipped (shameless for sale plug).

Bahamut got it right. The mirage guys managed to find a way to adapt the earlier 1st gen Eclipse TB with the 1st gen TPS to the mirage manifold without problems.

http://67.15.109.176/phpBB2/viewtopi...t=7105&start=0 (also need a mirage board account)

I am currently running the Eclipse 1G TB off of a 93 (I think) and a 2G Eclipse MAS, and I have no idle problems, and have been running this setup from since time began, at least for about 2 1/2 years. However, if you have the earlier TB, you might look into that mod.

Also to clarify what I was saying earlier, yes Rhyzin, you are correct about the 4G92 MIVEC IM. I saw one guy on the mirage board selling his for 275 bucks!!! Too rich for my cheap blood. But it does flow much better. If you can pick one up for cheap (or even the MIVEC 4G92 TB which is *reportedly* also 60mm) then more power to you.

 

so....look for a 92-96 turbo throttle body right?...are all the sensors gonna be the same...i dont really mind splicing wires and all that...but why not make it easier if everything connects....i think Kris got a 90-91 1g TB...but i dont remember right now....oh my IM should be here friday! yay...now i just need to learn how to port...lol

 

aargh, i might scrap the throttle body. things aren't working out. got the tps to work right. but i still got a high idle. cant be throttle closed sensor cuz we don't have one. not even built into our tps because there's only 3 wires connected to it and i see no switch in the circuit diagrams. probably a leak somewhere that i don't want to look for. wiring in itself sucks *** cuz you have to make wiring adapters for both the tps and iac. not really a worthwhile mod... grrrrrrr.... but i'll see if i can make it work at least....

i'm sure a mirage guy would want the throttle body in the end

 

so no go on the TB...huh?

 

well i couldn't get the iac housing off the eclipse so i couldn't swap with the lancer one. the screws are on too tight. anybody have suggestions?

 

92-94 G63T or NA for 60mm.


Here's the article
====================
Here is how to swap a 60mm DSM turbo or NA throttle body onto your 4G while keeping idle control functionality.

You will need:

High temperature rubber coolant hose.
You will need thin sheet metal (I used a floppy shutter).
Some silicone sealant.
Patience.
A phillips head screwdriver.
12mm socket.
Scissors or tin snips.
Probably a new gasket for between the IAC and TB.
Die grinder or Dremmel and bits (for Aluminum)

You may need new bolts if the mounting depth of your new TB is different. I needed to get new ones because my home made adapter was so thick.

There are three steps 1 performing the TB coolent bypass, 2 porting the manifold, and 3 the IAC swap.

1. The car must be cool and level. Find the coolant hoses that run into the TB. Reroute them into one aother with a new hose (or the longer of the two hoses). This will completely stop the coolant from flowing through the throttlebody. This is important because: You may not seal the new houring all the way, and your engine will inhale coolant and die, and this reduces the intake temperatures and improves performance.,

2. Get the throttle body gasket and some machinists blueing (or a sharpie). Bolt the gasket the the intake manifold without the throttle body. Mark the intake manifold for the 60mm opening. Now, port the intake manifold with the die grinder until the opening matches your markings. You can do this with the manifold in place, but it is recommended to remove the manifold and port it off the car. This way you have a more comfortable workspace, and less chance of pushing metal shavings into your cylinders. If you must port on-head, stuff a rag into the opening to keep the metal out of your intake. Be sure to vacuum the manifold well before starting the car. If you do this off the head , you can clean your intake manifold afterwords. Some folks like to take it to a self serve high pressure car wash, and blast the crap out of it, others like to use two cans of TB cleaner and kill a large spot of my lawn (stupid engineers).

3. Find a nice quiet spot to work. Unscrew the IAC housings from the two throttle bodies. BE PATIENT I stripped the screws on my turbo TB and had to buy a new set. Eight dollars for 5 screws is not funny. Besides when you strip them, they are very dificult to remove, due to the contours of the IAC housing.
Get your floppy shutter and your sturdy scissors or snips. Carefully cut out shapes to cover the holes that once held the coolant. Cut out a piece to cover half of the square (on the passenger side) of the Mirage IAC housing. Stick these pieces down with a little silicone, just to ensure they are airtight.

Check your work. Do your metal pieces completely seperate the chambers like they are supposed to? Are any of those metal pieces going to be sucked into your engine forcing costly repairs? Are you sure you will not ingest any coolant?

Bolt the housings back together (that is, Eclipse TB to Mirage IAC) They will be held together with three screws in the rear. You may wish to add some silicone to the non bolted side for insurance. Bolt your monster onto your manifold, and prepare for some nice gains.

AQ's link is the TPS fix article.

"why didn't any one take the time to look at the service manuals. It took me 2 mins to figure out the difference in the 1gen TPS and our Mirage TPS. it's all in the red wire. HINT: "closed throttle position sensor!!!!" from fastmitsu18 . . . the cali guys should know him since he knows Boe.

"mitsufreak your a genius. yes that's right people. you have been spending extra money or 2gen tps's when you didn't need to.

there is a reason why the 1gen tps only has three pins:

on the mirage, the TPS and closed TPS are included in one unit with a 4 pin read out.

on the 1gen, the sensor's are separate. the how-to in our forums stakes that if you use the TPS from the 1gen, you will get a high idle. that is because they overlooked the closed tps that was not wired up to the harness. as long as you splice the closed tps sensor into the stock harness, there is no need to buy a 2nd gen sensor, and the idle is just fine. I would know. Razz

anyways. I will write up a how to later this week so that the mods can include it in the how-to's.

oh yeah, and going from a 48mm, to 60mm turbo TB feels great. Shocked Very Happy

Use PB blaster or something.

 

ok, you see this wire coming out of the green tape I have there:

http://images.cardomain.com/member_i...86_55_full.jpg

this wire is your closed throttle position sensor (tps) wire.
you buy a wire connector called an easy splicer (it comes in blue or red, and has two places to put a wire and closes to lock them in place), shown below. You take that closed tps wire and you use the easy splicer to connect it to the yellow wire on your harness. shown below, it should be the wire that has no prong on the tps:

and viola. no more high idle.

for those of you asking how to hook up the hoses on the 91 4 port TB. here is a picture:

http://images.cardomain.com/member_i...86_57_full.jpg
you T the A1 and A2 together, E hooks up like the stock hose, and you plug the P port.


Happy tuning.

Quoted in the above article. Mirage guys have been fighting high idle nearly forever until someone took the time and effort to figure stuff out electronically.

BTW: I svck at electronic stuff, except testing for ohms. The author of this article has a 5g mirage and using a 91 TB, oddly enough. I still believe the 92-94 is tried and true.

 

good hunting guys . . . someone needs to get an E8 TB. Do what no Mitsu engineers never thought of doing to conservative 4G9x motors, excluding MIVEC.
