Both are "true" DOHC cam setups, F heads just run the second cam off of a scissor gear on the first. How both cams get turned isn't really a definition of whether something is a true DOHC head, heh.

The main difference between the F head and G head design is the valve angle, F heads generally allow for more fuel economy, etc, over G designs.

I don't think there was ever a 5S-GE, only the FE, and generally speaking, Toyota likes to appease the North American market with larger, more torquey motors, and saves the nicer engines for other countries, lol.

As far as available engines for the Celica in North America goes, it's as follows:

86: 2S-E (ST161)
87-89: 3S-FE replaces 2S-E (ST162)
86-89: 3S-GE (ST162)
88-89: 3S-GTE (ST165)
90-93: 4A-FE (AT180)
90-93: 5S-FE (ST184)
90-93: 3S-GTE (ST185)

Then of course the 7A-FE and 5S-FE for the #T20# series Celicas. Outside of North America the Celica had many more engine choices, much like other Toyota vehicles, in fact, the 4A-GE was used in the RWD Celicas for 83-85 in Europe, in fact for 84 models, even the 2S was used in the RWD Celica in Europe, along with the R and T series motors, and of course the 5M-E, 5M-GE, and 6M-GE in the Celica Supra and Celica XX.

It's all marketing. :)

Well, sorry I didn't dig up all the specifics.
Most people I know don't consider an engine true dohc unless both cams actually have their own timing. On the Celica boards it was basically F=ecomony head and G=racing head(I spent years on 6gc.net and celica.net when I had my 85 GTS and then 95 ST Celicas).
As for the fuel economy issue, I was getting 34 mpg in a 95 Celica(7AFE) delivering pizza. Sad part was the gearing, I could only get ~28 highway(80 mph was at 4k rpm).
Reliable as all hell though, it had 215k and still ran better the day it died(well, got totalled) than the day I bought it. And that was with SCCA Rallycross duty under it's belt. Broke 2 motor mounts, cracked a weld on the strut tower, killed the struts, but no ill effects on the motor. Even on the street I was kind of hard on it(mostly the suspension).

Forgot to mention in the first place, but the guys at 6gc.net have played with making a 7AGZE since the motor mounts are different between the ST202(GT) and the AT200(ST) which makes swapping the 3SGTE a little diffucult. Just do a search over there and I'm sure you'll turn up all sorts of A series info(4AG(Z)E, 7AFE, 7AGZE...). If I still had the Celica I'd have been swapping in a 20-valve 4A.
One of the best swaps I saw was on celica.net, someone swapped a camry v6 into a 93 Celica(can also be done to the 90+ MR2).

Yeah, it's sort of like trying to put a 1JZ into a pre-89 Supra, etc, different crossmembers/engine mounts, etc.

Custom mounts or swapping crossmembers would offer some help though. :)

The general consensus was that 3 mounts would work, and the 4th would have to be welded into place. Other than that it's a new trans(normally the MR2 turbo, the 5SFE trans works but would break too easily). For me it came down to that being too much power for a FWD.

And it's good to see another 6th gen Celica convert to a MKIII. I miss some of my friends from the boards and going to the meets, but I'm sure I'll make some friends in the Supra community and go to an occassional Atlanta or Nashville meet(once I get the dings pulled and get it painted, which will be after a lot more replacing of 20 year old parts).

My 6GC page
I had a black 95 hatch w/silver trim, 15" rims. I did the writeup for the 8" subs in the door. And yes, I was at PF 3 years ago with a dvcamcorder, it was the year we got a cabin and Brian wrecked on the way home(He wasn't hurt, and got a new one within a month). I remember your car. Still have the DVD around somewhere too.
I was actually thinking about trying to make it up there next year(wrecked the Celi 1 week before last years PF, otherwise I would have been there).
The best thing was when a few of us got together for a Dragon's Tail run. That was some serious fun. I wish I still had my old computer with all the vids on it.

yeah man, i'd like to get out there too, but it's sooooooo far away now... i'm still working on the st185 gt4 i've had for like 2 years not running right now... it's very close to being done.
