View Full Version : 3sge cams in a 3sgte?

GF has a 3sge that's somewhere between 86-89.

I've read about swapping the more aggressive NA cams into the 3sgte yielding positive results, and I figure while I have the cams exposed on my 3sgte, now would be a great time.

What parts do I need aside from the cam's from the 3sge?

You might have to change out shims in order to get the right valve lash, but aside from that I don't think you'll need anything. I would probably get adjustable cam gears though to tune the different cams.

PS: You should buy the cams out of my Gen 3 3SGE, you'd only have to cut the head "a little" to allow the lobes to clear. :)

gen 1 ge cams only go into a gen 1 gte. it yeilds great results and while you are at it go shimless on the buckets since you'll have to change all of them.

Where would I purchase the correct shimless buckets? and will I also need new springs?

Anyone have a writeup handy about doing this swap? I've never been this far into an engine before so it's all new to me.

Ok, apparently the buckets from a 1zz will work.

Step 1) Measure all 16 of my current buckets/shims and get their total height
Step 2) Order 1zz buckets that are the appropriate size
Step 3) replace existing buckets/shims with the 1zz ones
Step 4) Profit

New question: since the lobes on the NA cams are going to be more aggressive, won't that change the sizing of the buckets from what I have now vs what I'm going to?

No don't measure the current ones. Measure the ones that have correct valve lash to the NEW cams.

But from then that's correct.

No, you shouldn't need to change buckets. The heads are the same AFAIK between the NA and turbo, minus the cams themselves.

Doing this conversion over the winter with some ATS cam gears, I thought the buckets were because of the extended rev range??

They're also lighter. But the main reason would be either A: Big cams or B: High rev. The reason is that the Gen 1 and Gen 2 3SG(T)E buckets are shim over (the adjustment shims are placed above the bucket, below the cam lobe) and the shims can catch with A or B and get thrown from the bucket.

you have to change the buckets everytime you swap cams. bottom line. or halfass it and throw in some cams and see what happens.
they are not 1zz buckets for the gen 1 motor. canadian echo buckets. what ever motor that has. 1nz or something like that. there are several writeups.

1nz would be Echo, Prius, Yaris, Scion Xa and Scion Xb Gen 1.
