a little more power from 4y-e

[EldarO]

the benefit of the SC12 and 14, is that you can have them on a switch, which means that you can run the car with the supercharger off, and have good fuel economy, but when you ned the extra power, flick a switch, and get a bucket load more torque...

it sounds like you dont need it all the time, so id suggest doing this...

sorry to dig once more gentlemen

I've been working on this whole supercharger thing and it looks like you guys know what your talking about A small turbo might be a better setup after all The s/c is a bundle of hassle by the looks with pulleys and the like and trying to keep my accessories. Plus I need to think about a new exhaust manifold and exhaust anyway.

I know nothing about turbos beyond how they work Help me out here....... here's what I need/ want...............

* boost @ 5-6 lbs (maybe adjustable out to 10 tops depending on the extra cost of that adjustability)

* Come on song as low as possible. Anywhere beyond 4500 is a complete waste of time with this motor... its just noise.

* Ability to run PULP no worries.... ULP in a pinch

* The lowest cost possible for a reliable setup. Its an old truck but I don't want a rubbish setup.

SOOOOO..... what do I need.... who do I see (Bris).... what kind of coin??? I'll need some custom work yes????????????????

[stradlater]

Seriously mate, at this point you'd be better off going for an engine conversion. by the time you go turboing this thing and farting around with everything, you could have bought an already turbo engine, sat it in, and had the ECU wired up for about the same cost as all the stuff your talking about doing now. I know it's probably not what you want to do, but it'd be the wisest option.

[myne]

I dunno, I mean, realistically all he needs is
turbo manifold
turbo - t20?
bit of inlet piping
some rubber tubing
hoseclamps
and to pray the stock AFM can handle the extra flow.

If he keeps it small and low boost that should be all he needs

[Norbie]

Yes, that's "realistically" all he needs - but it's a shitload of work to do everything in that little list! And there's no guarantee it would last long before blowing itself up.

[stradlater]

it's easy to say that that's "all" he needs, but as norbie said, there's always shit loads more involved than you think, AND there's nothing to say you won't cook the motor.

[myne]

Sure there is.
There's always a chance it could blow up, but lets think a bit about that.

Reasons it probably wont blow up :
Toyota engine
Very low planned boost
Very low revving.
AFM

Reasons it might blow up :
Stock pistons
Old engine
AFM doesnt have enough range to cover the extra 40% more air flow.
Injectors unable to cope
Computer not up to it

Chances are good that it'll hold together though. Since it's AFM it knows how much air is entering. All the computer will see is extra airflow and add more fuel. Toyota ECU's typically run on the rich side, so a lean out is unlikely meaning the pistons probably wont be a problem. The injectors should cope because the airflow peak value will hopefully be close to the stock peak, but at a lower RPM. Instead of 150CFM at 7000, it'll be 160cfm at 3500. It's also a Toyota, and assuming it's not thrashed out, its' inate overengineering should get it through unharmed. Hopefully knocking wont be a problem with PULP on an engine designed for 89 octane.

[stradlater]

An AFM can max out you know... It's not just going to infinitely read the amount of air going in.

[myne]

I listed that...

[-mick-]

An engine conversion would have been preferable from the start guys BUT its an auto.... A340H....... and nobody has been able to tell me what if anything that might match up to I'd be happy to do an engine swap but I don't want to swap out the gearbox as well. Too much buggerising around with crossmembers, cutting holes, clutches etc.

That's why I was trying to make the best of what I had there. That and it had a full rebuild 10k ago.

I'd love a 3rz or a 5mge or something but I don't know what fits up to my auto. I would especially love the supra motor actually but no idea what auto they fit up to and no one including shops has been able to tell me.

Can you guys tell me what toy motors fit my A340H????????????

[Norbie]

Well my JZS147 Aristo front cut came with an A340E, so the bellhousing from that will almost certainly fit on your transmission, which means any JZ series engine will bolt up. I think 7M's used A340's as well?

[myne]

I believe the Y series and the S series engines share bellhousing bolt patterns too.

Though you'd be back at square 1 again, and trying to find a 3sgte.

I'm pretty close to square 1 anyhow dude.... actually its just round the corner.....

[-mick-]

ok the 7mgte will bolt up to my auto using the supra bellhousing..... sweet

Will the na 7mge be the same??? How about the 5mge etc??????????

Does anyone know this??? Will the non turbo 7m bolt up to my auto just the supra auto bellhousing as well??? How about the 5m etc???

Can anyone tell me which toyota vehicles came with the A340h auto Any of these will be an easy swap it seems if I can get their auto bellhousing, ecu and motor
