 Turboing the Beast

I am looking at turboing my Corolla. Does anyone have any suggestions and any idea on what it would cost to do this. It currently has a 5A in it and after driving a turbo Skyline for 6 months, to say the least, it is driving me crazy with how slow it is!

What about a 4AGZE? Supercharged! Easier and cheaper than turboing the original. Do you mean 4A?

Nah, she has a 5A in her, aftermarket motor. The auto trans also is like a 5 speed. It is like 1st, 2nd, then it just goes 3,4,5 all in a row straight after each other. It is weird. Dunno if it is stuffed or is meant to do that? Superchargers need hp to make hp I believe. That is why I would like to turbo it. Thanks for the suggestion though. The more ideas the better!!!

you get more low down power (which would be great for an auto) by using a supercharger... turbos requires you to be using the engine in high rpms to get boost therefore making you engine wear a lot faster than with a s/c'd engine
each to their own i spose, but, dont tell me... your doing this becuase you saw fast and the furious?

dont do the mistake all the "people" with their hondas do...turbo an original engine which wasnt designed to be turboed...all turbo engines have specific internals and are designed to be run with a hot turbo..like on a 7mgte, the block has different pistons to the na version, and it has oil squirters to help release extreme heat off he piston's bottoms. If you wanna go faster, either put a new engine in it - a 4agze, something fwd obviously...or sell the car and buy something better.

well, if you want a turbo corolla... there are basically two ways to go about doing it, without building a custom engine.
1. Buy a frontcut complete with a 4A-GZE engine. When you have the 4A-GZE separated, replace the supercahrger with a small turbo. Preferrably run aftermarket ECU. Been done plenty. This is the cheapest, easiest and least labor intensive way to go about it.
2. Buy a 3S-GTE. Squeeze the turd in with a lot of custom work. Go crazy. Expect a $10000+ bill for it to be done though. VERY FAST
I will make a note now though. DO NOT use an auto gearbox on a 4A-GZE. This motor produces enough torque to rip a crappy auto 5A gearbox in twain. To give an idea of relative strengths - a 4A-GZE gearbox weighs around 45kg.. a 4A-FE gearbox weighs around 30kg. BIG DIFFERENCE.

S13 Silvias and 300ZX's with the VG30DETT use T25 and T25G turbochargers, I don't think any of them were ball bearing.
Skyline GTR's, 200SX's/Silvias all used T28's of varying specs. Some of them were ball-bearing, none of them the same as Garrett's GT series turbos. Some of these, particularily the later S14A and S15 200Sx turbos would be well suited to a retrofit.
The other cars in the Nissan range that use the RB series engines or the single turbo VG30DET's use T3's of once again varying specs, some with and some without ball-bearing races. These turbos have been used time and again for upgrades, many people use them on their 4AGTE's.
Some of the smaller cars like the EXA and ET Pulars used T2's which probably wouldn't be any use in a real performance situation. So that leaves possibly the Micra/March Super Turbo which may have used a smaller turbo. Given there close connection with Garrett, I don't think Nissan would have any need to use any Hitachi turbos.
Maybe you are confused with Mazda (who did use Hitachi's also) or maybe you just didn't know in the first place and you are making shit up again. 
As for superchargers being suited to larger engines and turbochargers not being suited to them, what have you been smoking, I want some? There is a proper sized turbo or supercharger for just about any application. Turbocharging a non-turbo engine has been time and time again, there are quite a few Hondas that have turbocharger bolted onto stock engines and run for as long as a normal one. Its all in the tuning, having fortified internals helps if something goes wrong, but as long as everything is kept under control there is no reason why turbocharging a non-turbo engine is going to cause adverse problems provided it is done correctly and without going stupid. Please Robbo, feel free to give advice if you understand what you are talking about but its quite obvious that in this case (and some others) you don't. People come onto Toymods for advice, if you don't know exactly how to answer the question, don't try to piece together something you *think* could be right and try to pass it off as factual.
end rant
Sorry everyone for the length of that. I hope someone can take something from that...
....GT26, hehe
