7MGE running on 7MGTE electronics NO TURBO

[MA70AEROTOP]

Hi guys Just wondering Ive purchased a good running 7MGE recent rebuild now i think its too good to stick a turbo on it as i dont want to bust it up. Now will the 7MGTE electronics run the 7MGE? My plan is to use the intake manifold off the 7mgte and injectors. will the car run ok...


Now if i did want to use the turbo there should be a oil drain on the 7MGE ?? blanked off or something?

 

[MA70AEROTOP]

anyone lol

Yeah, as long as you use all the proper electronic parts (like GTE in injectors as you mentioned, ignition system and so on) it run perfectly fine. The only functional differance between the two systems is that the GTE EMS can (in simplest terms) hand more air flow and thats it.

Yes, there are some significant differances but nothing that is going to cause any issues as long as all the proper electrical equip. is used....

 

[MA70AEROTOP]

cool man thanks for that.....my plan is mod the sump for a oil drain then cap it off... like this ill drive around in NA for awhile then if i get board TURBO TIME....the engine runs that smooth I feel scared to wack the turbo on it lol...

To do the drain correctly you need to remove the sump and drill the passages, the pads are all there just undrilled.

If you do the return into the pan make sure it's NOT in line with a rod and keep it as high as possible. (not a big fan of doing it this way)

Hello 1J.. would it be ok for me to drill out the pads with the block fully assembled...I need to swap sumps so i can do the drilling and tapping then.. my Idea was to use my powerfull magnets to catch all the fillings plus vacuam cleaner. I myself arnt a big fan of the oil pan either but thought that is the only way.

 

[IJ.]

Yes it can be done just go slow and use some wheel bearing grease on the drill bit to catch the chips.
(that's NOT a 1 it's an I"

 

[cjsupra90]

Just Ian (IJ) said, drilling into the factory drain pad is fine on an assembled motor as long as you go slow and use a good thick grease to catch the chips... I have done it more then once.... Just remember, the slower the better. afterwards, if the engine is on a stand with no pan, you can easily clean out any grease and chips that might be inside..

 

[MA70AEROTOP]

very good Chris and IAN for 1 sec i thought hold on he loves 7Ms but his nick is 1J lol. yes defenitly going slow and buying a decent TAP! for the studs

another question OIL cooler. the 7Mge has no oil cooler would it be good to use the 7MGTE one? ive got a spare 1GGTE oil filter adaptor with the WATER cooled oil cooler I test fitted that on my 7MGTE block and it fits fine........ also would it be wise whilst the sump is off to shim the pump?.. since ive got a 7MGE complete and running recent rebuild and a 7mGTE BHG im planning to swap the 7mGE into the MA70 and possibly the GTE into the GA70 heheh i love 7MS!!!!!!!!

 

[IJ.]

Go for a full flow T Stat based cooler circuit.

 

[MA70AEROTOP]

any recommandations? brands I plan to run about 7psi with the 7mGe would that be enough haha. then again is the turbo needed? The 7MGE is coming out of a cressida i test drove it and lets say compared to the 1GGTE it moves only differance NO WHOOSH noises etc

 

[cjsupra90]

Yeah, dont even waste the time even thinking about the GTE cooler. Its just added weight that does nothing.....

Like Ian said, you want a T-stat controlled in line cooler. One of the best you can get for the money if you have a decent salvage yards around you is a factory Series 4 or Series 5 RX-7 unit. They have built in T-stats. They are a very good unit (have to be for use on a rotary being that 1/3 of the cooling of a rotary is done with oil).

 

[MA70AEROTOP]

This is for you Ian…I noticed on my 7mgte block the oil drain hole has a piece of cast iron in front of it. When drilling out the 7mge will it be the same? Also for the oil supply is it the same thing? Just drill out? Nothing to look out for….I am also still deciding if Ill keep it NA…..I might drill all the things to suit turbo then block them off try the car in NA form and if I am board wack on the turbo hahaha

 

[IJ.]

The Pad is cast into the GE block it's just undrilled, Drill a Small guide hole, I use a piece of rubber hose over the drill bit cut to make a stop at the stock hole depth.

I drill in using a 5mm bit then down from the bottom pad to make the holes intersect, I then open up the side hole to the same diameter as stock again using hose as a stop on the drill, flip the block and repeat.

You will also need to drill and tap the 2 bolt holes for the flange if you're going to fit up a CT26.

Same deal on the supply if using the CT26 hardpipe, personally I wouldn't I'd using softlines as I believe it makes life easier (never fitted a CT but I hear it's a bitch of a job)

If you go soft lines there are a few "spare" pressure points on a GE block you can use easily for supply.

 

[dumbo]

i would deffenitaly get a soft line kit from rabidchip. i did but i also welded a bung in my oil pan, so far so good.

i also bought a stock gte oil cooler and filter adaptor...garbage:3d_frown:

bought a canton adapter, permacool thermostat and remote filter head and b&m cooler. much nicer.

never been in a turbo supra, or any other supra for that matter, but 7m-ge block with a ct26 @stock 7-8psi:love: its amazing what 8psi can do

 

[MA70AEROTOP]

cool. so you have done a NA T conversion aswell.....how do you find it? Iam making mine so i can run NA for the time being till I get a oil cooler kit...just cap off oil drain etc.... as installing the single turbo CT 26 wont be that hard....at this stage ill be getting my MA70 working then ill upgrade the GA70 to a 7MGTE also 7MGE/GTE = LOVE

Also Ian whilst its NA is it best to run the 1GGTE oil filter adaptor with water cooling or just leave it the way it is till i can get a cooler?

 

[IJ.]

Did a bunch of NA redrills early in the piece as that's what I had available, I ended up buying a new GTE block though as I felt it was needed after 500+rwhp.

For a full flow oil cooler/filter system you need the block adaptor that will screw on in place of the filter a T Stat hoses a remote filter mount and the cooler.

There are lots of budget bits available to build the system or you can spend some $ and get billet parts.

Local delivered MA70's came with a stock cooler fitted.

 

[MA70AEROTOP]

ah so that means the 7MGE will have the fittings for a oil cooler?? its coming out of a mx83 cressida unfortunelty doest arrive till saturday/sunday. So Ian it seems like your the man for the 7Ms. well the both 7ms will come with there Stock filter adaptors but ive got the 1G filter adaptor that water cools the oil thought maybe I could use that whilst its in NA form....where can I find a cheap but effective oil cooling system

 

[cjsupra90]

No, not fittings for a cooler. Unless there is something different with Ausie 7M's, GE engines just have a stud sticking out of the block for the filter to thread on to. GTE's have a adapter unit that hangs the filter off of it and on that adapter there are line connections that go to the factory cooler...

There is no need for a cooler whilst in N/A form.
