Beams 3sge vs Sr20det vs 3tgte

[spencer]

The reason they use 3T,s so much in the states is probably due to the fact most of their corollas came with them and any late model performance jap engine is gonna be big $$$.

True for some guys but I think they just have a boner for the 3T-U, some top cars are running methanol and have carbon brakes etc. There is no money shortage, they could get any engine they want in the car for less than the price of the brakes. Also making a shitty 3T run 7's would be strangely satisfying

Build a 3t dude, but steer clear of the G stuff, just use a pushrod donk, it will be sweet. With head work and valves those heads can flow a shit load (for what they are)

[Babz]

Hey spencer. You know what you talking about. Stay away from the G's and stick with the Pushrod motor. They definetly flow more through then the G geads. 3T it is.

[xsspeed]

Yeah, mate just do it, if you have your heart set on it.

Looking forward to results/progress

[spencer]

I've been keen on one in a starlet or something for ages, I just love all the billet rocker gear etc you can get for them. Would have to be a drag car on meth for me though.

The blocks and heads are very agricultural on the 3TC/U guess its another reason they may use them, they can take allot of boost if prepped. So get your wallet out and order shit loads of goodies from the states and start a project thread haha

[d1 mule]

hey ill just put a worked 253 in instead of that mint LS1 i can get.............

as you say they get good power out of them cuz thats what they have and what they are used to tuning, we have moved on from push rods over here man.

Id be listening to willy aka 4agte power, he built my motor and has one of if not the fastest and most powerful Aw11s in the world, he knows his shit

[spencer]

There is always more sensible options with projects and then there's fun stuff that costs heaps of money. People work all sorts of inferior motors all the time, its not being built for any specific purpose so why not?

are there any 7 sec 4ages in the world? not trolling, serious question

[rollaholic]

did a quick google search for 7 second 4age. got quite a few results talking about 7 seconds to 100km/hr, hah

[Mr Revhead]

Woah! that fast? Must be 20v ones!

[Babz]

Woah! that fast? Must be 20v ones!

Yeah must be black top too.

as you say they get good power out of them cuz thats what they have and what they are used to tuning

They have more then 3T's. And we get good power out of twin cams because that is what we are use to.

Do your 3tc man, post up results and enjoy your project, its of no consequence to me or anyone else on here, you asked a question, we simply offered advice,
A 3tc/g doesn't excite me what so ever, sure a soild filled 3tc with a huge turbo running on meth is impressive in a 7 second drag car but any non v8 powered 7 second drag car is impressive in my books and the same can be done to a heap of other four cylinder motors and has been countless times. Look at the likes of mazworx's in the states with there sr20's, APC in Aussie and Speedtech right here in nz with there world beating 4g63s I like to see people pushing boundries with import engines and forging new ground.
I realise that my mr2 is not everybodys cup of tea haha in fact probably only a select few but it is mine and I enjoy it, so you should just do the same and build what you want.

[Babz]

Mr2's are freaken awesome. And putting down numbers like 511hp out a 1600 more then impressive. I understand that a DOCH replaced pushrods so im guessing the Japanese saw some obvious advantage. Like higher revs and ability to hold better timing at higher revs, runs more smooth too and the list goes on. I just want to see why the hell guys have such a boner for 3T's in so many countries so what better way to find out then to build one. We all might learn something from it. So i definitely appreciate the opinions.

Basically. Il do the build and if i am happy with the motor, chuck a 3tgte into the Carina and buy a RWD starlet, chuck the 3T in there and a big ass blower and see what numbers i can get in the quarter mile. SO basically i am hoping to run into the 9's with no more then $10000 spent

[TRD Man]

Why mess around with 4Y when custom length cranks are availabel off the shelf.

Where from?

[RomanV]

So is there any scientificish reason for preference for the pushrod engine, or is it perhaps to fit into some racing classes where rules dictate it must be pushrod engine or something?

doesnt make too much sense to me...

[TRD Man]

There is some scuttlebutt around, in fact it was mentioned earlier in this thread, that the heads flow better than the DOHC engines.
I suspect it's a bit of an old wives tale. I've heard the same said of the 4AFE compared to 4AGE.

The more likely truth is that the DOHC engines were not installed in any model that Toyota sold in the USA.
These engines only became available as 2nd hand units from parts importers but there was no manufacturer support in supplying replacements components when they were needed.

So the Yanks played with what they had and an industry has been created around that by a host of companies like the BRD Racing Babz has mentioned.

[Mr Revhead]

as above I reckon.
Add into the size of the market in the US and they can make a lot more fancy parts for lower cost.
