Can't see why not... The auto box may have a shortened life span though :)

Are then any actual guides to doing this? I presume just your standard altezza turbo kit is required and i would imagine a turbo timer, tranny cooler and aftermarket ecu?

Stick to the standard ECU for auto control and get a piggyback ecu to make fueling adjustments when on boost,

Definately pick up a tranny cooler

Ok sweet, thought so. How much of an HP gain would I kind of get doing this? I know it wouldnt be the same as a manual

You'd still pick up close to what you would with a manual minus the obvious drivetrain losses, the auto head is probably more reliable with its steel valves and slightly lower compression.

I was looking at building a BEAMS my AE86. Maybe turboin or building a 5SGE if I ever want more power.

I have picked up an Auto BEAMS half cut because it was pretty cheap do you think I should work with this or sell it and buy a manual setup?

I also bought the auto because I don't really care about the tranny as I was going to swap it for a W series box.

Stick with the Auto engine, no point selling it any buying a manual if your going to be converting it to manual anyway. Auto engine would probably be more reliable anyway.

How's the auto engine more reliable? You've been saying that abit lately.

The only time it'll have an advantage is if you smash your valves into a piston (Auto being steel will bend, manual being titanium will shatter putting bits of valve through your engine) Apart from that the manual head is better, correct me if I'm wrong but the valves are bigger, cams are bigger so the manual head flows better, which is ideal for a turbo.

Apart from that they are both as reliable as each other.

I know the reply to this but im going to ask anyway, If i was to obtain a manual head and bolt it onto the auto engine, while still using the tiptronic box, im presuming it wouldnt work?

Always been kinda curious :P

I'm saying its probably more reliable because it has a slightly lower compression, and the valves are plain steel.

Its been mentioned here before that the manual has/is more likely to drop a valve.

It is true that the buckets are smaller and the cams aren't as aggressive in overlap and lift but is that really worth the hassle of swapping over the head?

You could bolt up a manual head with the auto loom and just use the auto ecu and run a piggyback with a tune if you really wanted to go down that path.

I wasn't saying in reply to this not to use the auto, the auto is fine, just the reliability between the two is no different. Have enough people turbod autos to see if they drop valves? It's only under rare circumstances that the buckets come out of place (read over boosting etc).

In this situation if you already have the auto engine use the auto engine it'll be fine :)

Are the valve springs different in the auto? I've never looked in to it, that could be a problem as the manual ones are already on the light side.

I have greedy kit on my AT
the acceleration is crappy and I been trying to tuned it...
It is kind or hard to do it, and also I have a spare Beams G3 engine which is MT, which Im planning to put double head casket and make the compression to 10.5:1 and boost up to 8.7 psi just the spring with out boost control.
I have seen Leiden answer many question on the forum can u please help me out with the map and if its reliable to put almost 9 psi on a stock internal with 1.6mm head gasket? thanks

10 PSI is fine many people have done it even on 11.5:1, the TD04-16t on the greddy kit is on the small side so not a huge flow rate anyway.

The main thing to worry about it fuel. Always use best quality fuels to save yourself from detonation.
