3SGE Cams Upgrade

A great mod for the 3SGE is to upgrade the cams. For the rev 2 3SGE's, it is recommended that you convert to the 'shim under bucket' setup so you dont break your engine.

Here is a little write up

Toyota Celica DOHC (3-SGE & 5-SGE)

TOCD-6500: These cams are for hot street use, and will provide strong acceleration. The best power range is 3000-6500, and they will rev to 7500 in a well prepared engine. INTAKE: 28/62 EXHAUST: 68/22 DURATION: 270 LIFT: .403"

Necessary mods: PAECO inner & outer springs & aluminum retainers. A 1.0 to 1.5:1 boost in compression will give even more power but is not mandatory.

TOCD-7200: These cams are for very hot street and strip use. The best power range is 3500-7200 and it will rev to over 8000. INTAKE: 30/70 EXHAUST: 70/30 DURATION: 280 LIFT: .427"

Necessary mods: PAECO inner & outer springs, titanium retainers, 11:1 compression and a modified cylinder head. An aluminum flywheel will add even more acceleration and a Kevlar clutch is recommended for reliability.

TOCD-8000: These are all-out racing cams with tremendous power in the 4500-8000 RPM range. They will rev to 9000 in a well-prepared engine. INTAKE: 34/78 EXHAUST: 78/34 DURATION: 302 LIFT: .452"

Stock cams:

Revision 1/2 3SGE:
In: 244deg, 8.5mm lift (timing 7/57)
Ex: 244deg, 8.5mm lift (timing 57/7)

Revision 3+ 3SGE:
In: 252deg, 9.8mm lift (timing 7/65)
Ex: 240deg, 8.2mm lift (timing 53/7)

As you can see, for rev3+ cars – Toyota switched to a staggered set up. If you have a revision 1 or 2 car then you would actually benefit from installing rev3 stock items! A cheap upgrade route to go if money is at a premium!

If you want to go for a big name company then plenty of companies cater for this as the 3SGE cams can be used in a 3SGTE and vice versa. The stock 3SGE cams are also more aggressively profiled than the 3SGTE items – this is why some owners in the US have swapped out their stock cams for stock 3SGE cams.

An example of aftermarket cams are:

Piper Cams (fast road):
In: 260deg, 9.37mm lift
Ex: 260deg, 9.32mm lift

With this setup you should expect circa 10bhp and they cost £450. If you have a revision 1or 2 car then you will need to have a shim under bucked conversion carried out if you intend to fit high lift cams as these engines have a habit of spitting out shims at high revs. The revision 3+ cars came with shim under bucket as standard.

Also, as you may know, 3SGTE and 3SGE cams are interchangable so there are a lot of options available for the 3SGE

Brands like HKS do supply camshafts for the 3SGTE, details here:

Sorry to sound stupid, but am getting a little confused by rev 1, 2 and 3, guess rev 2 is the st182? and the rev 3 is the st202?
so if I was to put St202 Cams in my st182, is it just a straight swap?

Yep,

rev 1 3sge - ST162
rev 2 3sge - ST182/3
rev 3 3sge - ST202/6

Rev 3 3sge cams will be an upgrade for your rev 2 3sge. They should be a straight fit so you wont have to worry about doing the shim under bucket conversion or messing with the ECU.

Would be interesting to see the results!

I think i'm going to research into this a bit more, seems to good to be true

do i need to do any other work like shim under bucket conversion?

Well when I have some money, after Xmas now, I am hopefully going to get a set of cams, and try it out, see what happens lol.
but i wont be for a while yet

Awesome! Make sure you keep us posted, would love to see the results!

Going to see if i can get a cheap set from somewhere

^^^^ Same, good thing is know somebody with an ST202 wrecking, might try and grab his cams.

another place is kelford cams they do big, racing (300degree+) and custom sizes

a good size for gen 3 are about 264deg for the IN/EX you can get a slightly smaller EX cam for more low/mid power

Have heard good things about kelford cams, what i like about the gen 3 is it has the shim under bucket layout so you can have huge cams and not worry about destroying your engine

Will bear them figures in mind, someone PM'd me about gen 3 cams, hopefully this will help

has any one fitted st202 cams in their 182 yet?

i was told you cant use gen 3 cams with out changing to shim under buckets or shimless
