Any custom fabrication - be it turbo or SC - will cost you twice your budget (or so it's been for me).

Given that you've got - potentially - a high compression engine that had a turbo optiopn, i'd suggest you take advantage of it:

-get a 2nd hand smallish ball-bearing turbo - small exhaust housing too get boost on early and nothing to crazy on the inlet side. $200-$400 - something common so when it breaks you just get another one.

-get exotics exhausts to make a manifold & dump pipe ($500-700) or see if you can source a factory 2tgte turbo manifold $??

-get a 2nd-hand 2tgue intake manifold $??

-get chinese-made FMIC off ebay and piping/clamps to fabricate connections to/from turbo and the intake. $400?

-get a 2nd hand microtech or haltech ecu & injectors to suit projected power output $500-1500?

setup the fuel supply (pump, swirl tank, EFI hoses, etc) $250-350?

-learn to wire the engine - if this diagram (the fuel side of my EFI setup from sensors back to ECU) doesn't frighten you, then you're half-way there:

There was no factory 2TGTE, but if there was where can i buy one from?
The exhaust manifold off a 3TGTE might have the same exhaust bolt pattern though?

[lilcrash]

ace i do believe you are right, in my searching i have only found the 3tgte and the 4tgte. but the 3tgte manifold will bolt straight on, and i have a manifold and a turbo/dump pipe sitting here if someone is interested. ive also got the efi inlet setup but i dont think i will get rid of it cheaply.

turbo option will always be cheaper.

good luck with the conversion

Yep, the 2T, 2TG, 3T and 3T GTE exhaust manifolds are the same. Only difference is that the 3T GTE manifold has slightly bigger bolt holes, but there are in teh same spot so its not a big deal and still fits.
The inlet manifolds are different.

There was no 2T GTE from the factory. The 3T GTE was first, along with the 4T GTE which is basically identical to the 3T GTE apart from the pistons that are only 0.5mm bigger.
Toyota also made the 4T GT race engine, but forget about finding one of these. Only a handful were made and produced up to around 600HP using a huge KKK turbo.

my bad - i thought there was factory turbo 2T...but - concept is still valid. - i'll leave post as-is to make sense of the posted corrections.

fwiw: Doing the turbo + EFI conversion is a big learning curve, but a great learning experience. I'd recommend it only if you can go without your car for extended periods of time.

Hehehe Im back into thinking mode about this scenario. Mainly because since seeing this Im now pondering how it all works:

I still probably wont put the SC on in the end, Im just interested to know how it works. What's stopping you from making up a plenum to incorporate both carbies I have? The SC would be running minimal boost anyways, surely it could be done!
If I were to do it on 51LII it would be for shits and giggles and to have some fun and learn something new. I still thinks its such a crazy-cool idea that would spin people out

[Grant]

This discussion my well be academic if an automotive engineer won't sign off on it. Best you run it by a local AE and see what he thinks. Others on this thread are quite correct though when they say that it will cost you much more then a factory 4AGZE.

[sillycar chick]

Thanks for your input, but regardless of whether an engineer is going to sign off on it, I actually just want to know how it works, and what's involved, as people have run forced induction on carbies before, particularly in the US, and gotten great results out of the setup. If anything I want to learn something here, after all that is what toymods is about.

If anyone can help me out on how it all works it would be appreciated

I got this wierd guy sitting in the shed, no idea what the point is but it came with my motor. IT could be re-sealed for use in a blow through solex setup



Theres nothing stopping you doing what you want to do, and if you do ALL the work your self it will cost 2/3'rds of fuck all. As soon as you pay someone else to do it your better off with a conversion

[sillycar chick]

OMGGIMME!! If it would work for a SC setup I may take it off you depending on how much you want for it... just dont sell it till I decide ok

Can anyone tell me if it would work?

Despite people's opinions that it would be better to get another engine (i have a long term 3TGTE build in progress but funds are limited at present so please dont even suggest im better off with a conversion), I would like to give it a shot just for the oddity of it. I have a SC12 or whatever it is at home, I just like to be different, prove a point and learn something new. Surely some of you on here can appreciate that.

Sooooo who's going to help me make this work?

interesting idea... ever notice any difference in performance with/with out it? looks like it's probably intended to give great low-down torque, no idea....

[skiddz]

thats ghey, dana dont fuck around with p00 (T series is the new 7m) ..... but yeah save for the 3t build ....do eeeet

[sillycar chick]

Oh shut up skiddz, its not like i'll be spending much money if any if i do put the SC on... It will all be made by me, im not going to pay for fab work, I have a bunch of guys at work who can do that for me for nothin Will be something to have fun in because I want to take my time doing up the 3TGTE/TA22 properly.

You just want me to sell my SC to you instead dont ya

lol... YOUR 2T is the new 7M... 2T's aren't nearly as bad as the 7M's...
