Killswitch Posted October 20, 2006 Author Report Share Posted October 20, 2006 They mention the 4Y crank in the toysport article Retrospekt posted, seems a bit extreme. So exhaust manifolds do fit, that's good to know. Way to confuse me Redwarf :) I've a question when it comes to this, will manifolds swap across between 3T and 2T heads? After some searching it appears exhaust will be intake won't, is this correct? No, the manifolds are completely different. No interchangy's there. Yep, exhaust side the same, inlet completely different. Thanks for the confirmation anyway towe001 and Redwarf What's the 2TGEU injection gear like? Worth following for N/A applications?

Redwarf Posted October 20, 2006 Report Share Posted October 20, 2006 Ooops, sorry. I can difinitively state that inlets are different, and exhaust is the same. My apologies about the confusion. :) Quote Link to comment Share on other sites More sharing options...
styler Posted October 20, 2006 Report Share Posted October 20, 2006 i have 2 hybrid motors ;), i have been into the hybrid motors ever since i found out how awesome corollas are :) my first rolla had a monster 1940cc dual twin 45 weber and early head which has the more aggressive cams as well as numerous other mods. 1940 is too big, and the bore walls will be too thin in my opinion. around 1920cc or less is a better spec (88.5mm max bore is safe) the hybrid is a fantastic motor setup for many reasons: almost bolt in for ke rolla (the entire conversion) few gearbox options twincam head 8 big valves (16 is just too many :) ) extractors avaliable and fairly priced the locally made 3tc parts are interchangable with late model 2tg you can still get twincam parts and performance parts a few stock cams with different grinds $100 per cam for regrind to any spec webers work well and still avaliable inlet manifold is twin sidedraft as stock, also avaliable from redline quite a few 2tg parts still around to replace old components t50 is starting to get expansive though - takumi tax w50/w55 box easily fitted crossflow motor! with alloy hemi head! reliable valve train but must be setup 110% right solid strong bottom end 3tc pistons + rings + flycut $300 cheap :) (also must use 3t crank!) local 2t motor can be used for replacement block with few mods borg warner diff holds up if you don't dump the clutch and be reckless. makes decent power and torque across most of the rev range :) and many other advantages... but: it is quite an old motor. it has to be set up 110% right especially the head!, if you are doing it yourself it takes some patience to make sure its all set up right - cams etc, else get it done professionally. some parts can be expensive like some of the timing gear but most of it is pretty cheap considering other new motor part prices! you need to spend quite some time researching and a bit of cash fully decking this motor out properly and it will be an awesome motor, else it will be pretty average which is common and still works well in a rolla. a lot of people have moved on to the 4ag series of motors: 4ag 16v, 4ag 20v, 4agze, 4agte (custom turbo setup ) as a newer alternative with is own 4ag series pros and cons. anyway : it doesnt have super mega 300hp, but it doesnt need it if you have a well setup car (suspension etc) which is light - around 800kg, its very fast around a track! wont beat a v8 commodore on the straight but would lap him around a raceway lol.... :D i rate it! :) Quote Link to comment Share on other sites More sharing options...
Retrospekt Posted October 21, 2006 Report Share Posted October 21, 2006 Exactly what i was told when i bought mine, also that with a 4age and 2tg both will make roughly the same power till a point, then the 4age can make more but costs extreme amounts of money to do so Quote Link to comment Share on other sites More sharing options...
love ke70 Posted October 21, 2006 Report Share Posted October 21, 2006 http://en.wikipedia.org/wiki/Toyota_T_engine The Toyota T engine series was later replaced by the Toyota A engine series. I'm sure there was a reason :) and at the end of the day making a hybrid WILL NOT be cheaper than a 4age conversion. sure the conversion to 4age is common on forums...but how many people do you KNOW that has one... and you can even get the decompressed motor and turbo it. and its a metric f@$kton stronger than a T motor.

Retrospekt Posted October 21, 2006 Report Share Posted October 21, 2006 I'm talking about building na engines, parts to build a tough 4age are going to cost alot more than a 2tg, i got lucky and scored a 2tg that was already worked. the guy i bought it off now uses 4age's and it has cost him alot more to build it than the 2tg. btw wasnt the 4age a mass made version of the ford bda?

love ke70 Posted October 21, 2006 Report Share Posted October 21, 2006 how much power are you chasing? 200 hp...easy completely stock internals and it can be done read billzillas site Quote Link to comment Share on other sites More sharing options...
irokin Posted October 21, 2006 Report Share Posted October 21, 2006 AFAIK ANY injection that came on the T motors is absolute rubbish. Use side draft webbers... Quote Link to comment Share on other sites More sharing options...
Retrospekt Posted October 21, 2006 Report Share Posted October 21, 2006 wasnt chasing huge power, just wanted to do a 2tg rather than 4age for ease of conversion and could do almost all the work myself. the engines i am talking about had alot of work done, to the point there were no stock internals, just repeating what i was told and that is that his 4age didnt make much more power but cost a whole lot more.

ancullen Posted October 21, 2006 Report Share Posted October 21, 2006 btw wasnt the 4age a mass made version of the ford bda? Kind of. Toyota pretty much ripped off the design of the bda, but it was a damn good design, so why not? As for the 4A-GE versus 3T-G argument, if you're not seeking maximum power, I'd go the 3T-G, simply because it's cool and a bit different (in a KE70 anyway). If you want to build a big horsepower turbo motor, then go the 4A-GE. Buy a 4A-GZE, then convert to turbo for an easy 120-150rwkw. However I've got the impression that you're being quite sensible and just want a quick-ish street setup. So the 3T-G is the way to go. And twin Webers would be way cool!

Redwarf Posted October 21, 2006 Report Share Posted October 21, 2006 and its a metric f@$kton stronger than a T motor. Remind me to show you what a decent 2T_G can do. As for stronger, it all depends on how it's built. Quote Link to comment Share on other sites More sharing options...
Redwarf Posted October 21, 2006 Report Share Posted October 21, 2006 (edited) how much power are you chasing?200 hp...easy completely stock internals and it can be done read billzillas site It can be done, but how long does it last for?? Injection for the t motor sucks the big one. Webers are the go, 45's on a hybrid. You'l NEVER get a 4AG to sound like that! :) Edited October 21, 2006 by Redwarf Quote Link to comment Share on other sites More sharing options...
Retrospekt Posted October 21, 2006 Report Share Posted October 21, 2006 yeah ive got dhla 45's, still havent heard it running because i can't find time to do the engine swap :/ Quote Link to comment Share on other sites More sharing options...
Redwarf Posted October 21, 2006 Report Share Posted October 21, 2006 When you get it going, I'll come around with a chair and a six pack and we can listen to it going around the block a few times.. :) Quote Link to comment Share on other sites More sharing options...

My 4A-GZE sounds pretty freakin' cool, and that's standard. Plus, if you really love carb noise that much, go the twin Webers on a 4A-G. Or quad throttles for the win! Proof that 4A-G's DO sound good! Quote Link to comment Share on other sites More sharing options...
