Celica engine swap Q's

2319 Views 4 Replies 2 Participants Last post by  oldskoolceli
I have a 1979 toyota celica gt. I found the engines that can fit in my car: 4A-GZE, 18R-GEU, 3T-GTE, 1G-GTE, 7M-GTE, 2JZ-GTE, 3S-GTE, 1UZ-FE. I wanted to know if anyone knows what engine can fit with the least amount of modifacation.

Depends what you want...

The 4AG is too small IMO, the 18RG is quite rare, the 3TG is also quite rare, 1ggte/2jz/1uzfe are all quite difficult involving quite a bit of wire work... and the 3SGTE will be very very difficult to mount up because they all come in transverse set-ups only (plus has a lot of wiring). Basically, just about anything EFI would be quite difficult to do...

I'd personally go with the 3TC. With a bit of build-up, those engines can make a lot of power/torque and they are bulletproof...

Other mentionables... 20/22R hybrids will probably be the easiest... and they do make good torque/power also...
well i have a 20R, but what and how would I build up the engine??? Its carbed..

Carb is perfectly fine for making a lot of power. You can make great gains with some side-drafts and a bit of tuning. The 20/22R hybrid motors are pretty cool and make a bit of power... and money-wise, they're not all that difficult or expensive to do. With some headwork, a 20R head on a 22R block can make for some very nice gains.

which one of these would be best for a build up.... Intake Manifolds

Both the 20R and 22R Down Draft Intake Manifolds have a large open plenum that provides power gains at all rpm’s with good torque. Excellent for use with Weber 32/36 (page 28) or 38mm Carbs (page 29). Custom adapters are available to match this manifold with the Holley 500 or 350 Carbs for circle track and off-road applications.

Holley 4 Barrel 20 R Large Plenum Manifold

Out from the archives, Holley 4 Barrel 20R large plenum manifolds. Adapt this to the 350 or 500 2 Barrel Carburetor. Excellent circle track application. These manifolds are designed to work with circle track, off-road and performance street applications. To get these custom designed manifolds off our shelves and onto your engines, we're going to practically give them to you at only $150.00 each.
