Witch way to go?

Ok I have an average MA61 supra with a good 5ME, its got heaps of torque but it eats petrol flat out. I have a 1G-GTE that is good 2 but being a small eng will it pull ok in the MA61, it has a T4 hybrid and is happy to put out about 160rwk. I am toying with 2 ideas, put the 1G in or decomp the 5M and fit the T4 to it, with a fuel/ignition computer.
Any one know if the 1G will go straight in to the factory mounts?
Has anyone turboed a 5M?
All pros and cons are wanted, I want a car that will pull hard from low end all the way through the rev range, the 1G is a bit lagy from when it was in the corona but thats because of the exhaust i had on it.
I just want a reliable car and dont want to go over the top, im not out to prove anything just want to beat a few cars other than V6 commo's

if you're planning to put that turbo on the 5m and work the 5m, I'd seriously look at the cost of a 7M-gte conversion

Many would tell you the 1GGTE is too small an engine for the Mk2. In reality its not, its just that the engine bay is capable of taking many larger engines.
The 1GGTE will bolt to the mounts from a GA61 providing you have the matching front-sump, which is one of the reasons I wanted a 1GGTE.
If you're wanting something without lots of lag, perhaps the 1G with the big turbo isn't the best thing.
As for turboing the 5M, don't bother. Just buy a turbo engine like a 7MGTE to begin with or even better a 1JZGTE or 2JZGTE.

Yes, a turbo 5M will give you no end of grief. The 1G will be ok but I suspect it won't be the most drivable car in the world with the lag you're likely to have. Still, if you have the engine already I say go for it.

If you do decide to do the 1GGTE let me know if you have any problems

How heavy is an MA61 anyway? My RA28 is a bit of a porker for a small car at 1200kg. Bearing in mind that you would be saving a fair bit of weight with the engine swap, I would have thought it would perform quite well.

GA61 Supras were apparently around the 1250kg mark. With the extra turbo hardware he'll probably be a bit more than that, but still less than 1300kg (at a guess).

Hey ED, You have just made me a happy man.
I just had a look at your web page, particularly the artical on the RA60/MA61 strut comparison.
My RA28 has MA61 struts and brakes in it with the control arms pretty much parallel and eccentric bushes on their inboard mounts to get a total of -0.5 degrees camber. Suffice to say I have a pretty horid roll centre location and bump steer problems. I wanted to rectify this with roll centre adjusters however after drawing it all up I realised that it would give me a total of +0.3 degrees camber. 
Anyhow If I can recover -2 degrees with using RA60 struts it should be sweet.  -1.7 degrees total camber.

GA61 X-members and other bits turn up quite frequently in NZ. Here, you might have to hunt the wreckers on Trading Posts to find the nescecery GA bits. As others have said, if you already have the engine - go for it! The 5ME is ideal for ballast or anchoring large sea-going vessals.

Sorry i havnt been on the net for a long time, Ok for starters I have had the 1G-GTE with the T4 on it on my TT142 Corona. It wasnt lagy as when I bought the turbo it was built for the engine and I have kept the factory water to air cooler on the top of the engine so it reduces lag as the short track it takes across the top instead of around the front. That produced 170rwk and made it heaps of fun to drive. The corona was only 1000kgs and the supra is about 1250kg from memory, I dont know how much it will drop in performance for the weight, I guess it will be the same as when the corona was full, it still busted a stock WRX then. I dont think I will go for the lebo turbo conversion on the 5m. I will be wasting my time, I will endup blowing it up and putting in the 1G-GTE any way. So i will keep you all posted on when i do it and let you know how it goes. Here is a pic of my Corona, it might be up for sale soon, any offers?

, just not a great idea unless you have a really good reason for wanting to do it - ie want a project engine to build and toy with, and dont care so much about the performance at the end. effort/dollar/performance ratio is rather high
