[macavely]

OK has anyone got the 4A GE and Put a turbo on it
this is somthing i'm thinking about doing getting the 4A GE (whole front clip) and just adding a custom turbo.

Are you thinking about a 16 valve or 20 valve 4A-GE? I'm not sure on the compression ratios of the older 16v engines, but the 20v engines have high compression ratios that would have to be lowered in order to turbo the engines through the use of internal engine parts such as low compression pistons. Also, I don't think the internals on the 20v engines can withstand a lot of boost without modifications, so you'd probably end up spending a lot of money on hard to find internal parts from Japan, as well as the turbo, manifold, intercooler, etc. I think that you'd end up spending a lot of money, and it'd probably be cheaper to do a ST185 3S-GTE swap, plus chances are that you'd have more power, unless you really build up the engine and get some nice turbo components. On the other hand, it'd be very, very unique, and it'd be completely awesome to have a turbocharged, high-revving engine with the technology that the 20 valve 4A-GE has such as quad throttle bodies and five valves per cylinder.

Toda Racing offer all 4age 16v,20 parts

St185 would be a good swap

Either way, once you change to forge piston, you have the option for compression levels. You can either choose between 8.0 - 9.

If you are planning to turbo, go for an vavle angle job or a general head clean.

As I stated coomer, you can turbocharge high compression engines.

You only have to make sure you have gas and not too much boost like over 10psi.

The main problem I see here is the 20v since there can intake more air than a 4v head. So injector upgrades are neccessary. I think the 20v caris 280 or 310cc injectors. An increase to 420-550 would do very good.

I have seen more 20v engines damage here due to the lack of ffuel more than anything else.
