3tgte cam specs

[TheToyman75]

mmm Adjustable Cam gears..... Where did you get those ??

And since we seem to be posting up cam shaft pics, these are in my 2TG head:



As for fitting the 3T-GTE Cams into a 2TG head, Don't waste your time ! The 3T-GTE Cams have very similar lift to the 2T-GEU cams and the difference will just not be worth the effort.
As a reference Jasons 3T-GTE makes 210 rwkw on Stock Cams but if you still think thats the area you want to spend your money on then get a decent set of Regrinds, don't waste your time or money fitting stock 3T-GTE ones. The only Stock cams I'd consider are the 88222 cams being the highest lift of any Stock T series Cam, but the price of buying a set and reshimming the head..... Go the reginds !

I got them form Kameari, I needed them because I got the head shaved and the block decked to gain comp.
The amount of material removed from the head and block was a fair amount that when using the stock cam gear and lining up the cam notches facing up (for a base 'cam time' setup tune), you couldn't get the notch to line up with the arrows dead on. It was either on the left a bit or on the right and thats using the holes on each side and skipping a tooth.
I guess It doesn't help when you change the head gasket that matches your pistons (1.5mm) to a 0.8mm metal Kameari one.

I was going to drill holes in the gear to allocate for different position as you may have seen else where, but the adjustables (sp?) are a lot more accurate when combined when degreed.

Geez.. Rod, that inlet cam looks like it's got some torque and lift down low!. Would lve to hear those idle and peak.

Mate I can't wait to hear them either lol, its a hell of allot of lift on a very steep ramp so they wil be loud as all F#ck. I bought brand new buckets from Toyota to give them the best chance of survival. The cam specs may turn out to be to savage but we will see what happens. There is actually only 470 thou of cam lift on there Mind you keep in my mind my head has seen some excessive port development. Near peak lift the inlet side flows over 45% more than a stock 3T-GTE head and the Exhaust side is almost 30% more. Actually the Exhaust side is near on 30% more flow at every lift point

All my cam have had locating holes drilled to set the correct allingment so I was curious to hear about the Adj cam gears, the gears are so damn small. I'll have to take a look next time you have the engine appart.

Wow 11.937*mm! That and the porting to the head will definitely make a good combo, and I take it it's going on the F.I. 2T-G. Can't wait to see some progress.

Kameari gears:



and some slotted/re-drilled ones:

you would also drill holes in the cam too.

Damn they are some nice timing gears. It's a pity they're hidden in a oil storm when in use.

For the original poster though if there is any kind of budget involved big cams are about the last thing to do for a turbo conversion. The money is far better spent in other area's.

[w810sc]

I believe they are on a tight budget in boosting a 2T-G, using 2J pistons (read from other thread). Would like to know more in the build.

yeah I'm stuck with building with a very tight budget and hope to make do with whats more easily available...thanks to w810sc and toyman for the info and pics really GREAT stuff!!! BTW w810sc how much did you spent on the adj cam gears? and toyman whats the duration on those cams?

[w810sc]

30,000yen for intake and exhaust adjustable cam gears. You can buy 1 adjustable and one drilled/slotted for around 26,000 yen and or 1 adjustable for around 16,000 yen.

I've been told about using 2J pistons in a 3S-G motor but not a 2T-G thats why I'm interested in your build. For a bottom end like the 2J's that can handle 400kw+ stock (give or take) is promising.

I'm only at the planning stage right now and will be sometime yet before I start buildup, but will keep an update here. There's even a 3sgte running on 1jz pistons here so I'm really hoping that those are compatible with the 2tg so I can save some money. I'm thinking the only obstacle would be fly cutting for the valve reliefs?

I think your barking wellup the wrong tree with the 2J pistons. A set of 3T-C pistons in 0.5mm will cost you bugger all new and surely you can locate a 3T Crank ?

The 3S and 3T pistons are not the same.

ok so thats an idea down the drain, so how much save boost can the 3tc pistons take? and I'd still have to do some valve relief work on it right?

[TheToyman75]

How much boost they will handle really depends on how good your Dyno tuner is. The Stock 3T-GTE pistons are cast items and with a good tune and diligent maintenace will actually take a good deal of boost indeffinatly. Dick has been running his 3T unopened since I was a teenager and Jason ran 20 plus pounds into his for over 12 months.

I'd happily run one at around a bar of boost all day and expect a longlife if its set up right and not allowed to detonate/ping.

How much boost did you want to run ??

I'm sure these are 3tgte pistons but unfortunately I've no chance of getting those here

hoping for something near 12-15psi and worried the higher comp 3tc pistons won't hold

[TheToyman75]

The Stock 3T-GTE pistons are cast crap

The Replacement 3T pistons are also cast, yes compression will be higher. (About 9.8:1 depending on what head gasket you use. Which will make for great offboost responce and should hand 10-12 pounds easily.

If you wanted to run around a bar of boost, fit a copper head gasket the extra headgasket thickness will drop the compression some. Get your engine builder to do the math for you.

ok everybody thanks for all the input and help you've been great
