I completely agree with what Redline03 said: worry about reliability.
Thats what im doing with my AE86 coupe...then the boost will come.
Ive had 5 AE86s and from experience Ill tell u that its a drivers car...its more about driver feedback than anything else.
Its very light (lighter than the S2k by a lil) and has an almost 50/50 weight distribution (something like 47/53)
The 1 and 2JZ swaps are usaully left to the drag guys...and requires a W or R series tranny and Supra, tacoma or a ford 9" rear end. Lots of fab work.
For a well balanced car I would go with any of Toyotas motors.
I grew up in the old school Toyota sh!t s thats what i gravitate to naturally...
Yes, the 22R is a good candidate, the 2/3TC, 2TG, 33rz, 18r, etc etc.
Most of these Toyota motors have interchangeable parts and swappable trannys (cams, pistons, heads and blocks)
And on top of that theyre mostly bullet-proof from factory.
After my 4th AE86 GTS im on my current 86, an SR5 with an old school 1.8 3TC swap, and mikuni side-drafts.
And although the Twin Cam GTS I had (w/LSD) was great...this is a completely different beast all together...
Ofc the SR5 is carbed and not fuel injected like the Twin Cam GTS so swapping in an old school carbed motor is much easier than swaping in an EFIed motor bc u wont have to swap fuel lines, wiring, and a mess of other sh!t.
BUT if u have a GTS, then a 4AGZE, 3SGTE, 20Valve Silver/Black top will be better...
The supercahrged 4AGZ and MR2 3SGT are more expensive to swap and the latter needs a Supra tranny behind it.
The 4AGZ can use the AE86 T50 tranny but an aftermarket clutch is recommended.
IMO, I would swap in the 20V Blacktop, and run open ITBs.
Awesome motor with great response.
So dude...its all up to you and what your goal is for the car (drifting, autoX etc)
u have MANY options BUT in the end its about your personal preferance.
Any questions please feel free to hit me up w/ a PM....:thumbup:
Peace.
