BEAMS Turbo SW20

[guiltysky]

I have a GEN3 SW20 with a BEAMS swapped in from a '97 celica. IF, that's a big IF, I was to go down the road of getting it rebuilt, forged and turboed with the whole shabang, where/how/who would be the best value place to take it to?

[dnalunchie]

depends if you want it down cheap or down right. Cheap, any old performance garage. Right. ST hitec. Best shop in auckland probably.

How much power are you hoping to make after turboing it?

Would be easier and cheaper to just pick up a Gen3 3SGTE from a SW20 and go from there.

The shop that tells you what you want to hear for the price you can afford generally becomes more expensive than the expensive shop once you factor in your car still sitting in bits in their workshop 6 months later and makes barely more power than your old bolt on setup.

Im guessing the beams heads breathe better and the cams are more agressive then the 3sgte ones?

Buy 3sgte bottom end replace rings+bearings gaskets and rod bolts

Bolt head on with new gasket

Work out comp ratio

Add turbo

Add ecu

Tune

Skids on ???

its roughly 2k for a blueprinted rebuilt bottom end using factory parts thats via an engine reconditioner

Its around 500-1k for the engine to be pulled in and out depending on who does it

are you going to run factory or bigger turbo ?

ecu is around 1700+ tuning

Running the engine in on the dyno and a tune is around 1.5k

you would also need bigger injectors and a better clutch

heaps of work

why do you want to turbo what you have?

what are you goals if your wanting 300hpish thatn a 3sgte (gen 3) would be a good way to go with alittle more boost then factory

VVTi provides faster turbo spool, broader torque curve for overall better performance.

i currently have a dual beams vvti head sitting here to do a 3SGTE build with

i'd personally look at forged rods, maybe some pistons or just a thicker head gasket to get somewhere around 10-10.5:1 compression, gull force 10 with some e85 mixed in to make E30 and go hard.

Remember beams motor has smaller combustion chamber, and different angle for the valves.

So 'low comp' 3SGTE pistons will still possibly be higher than what you started with, and may have interference with the valves/valve cut outs.

You wouldnt have change from $10k for a beams turbo rebuild with forged rods and pistons that runs decently, if someone else is doing all of the work.
Even more so if they dont have specific knowledge pertaining to this engine / higher chance of it being a bag of crap or shitting its pants.

Doing it for the experience or to be unique?

If not, save a whole lot of effort/money and just go with loudstealthGT-Four's idea.

Have you read Mandalay's thread on MR2OC.com regarding his redtop beams with rotrex supercharger ?

Good (and huge) read, he doesn't do things by halves.

fair point, maybe... but are you saying they dont know what their doing?

Wow, that its amazing work , is there another thread where he carries on?

It is up to part 12 or something?

O I see that was just one part

[Akane]

Just do what Al did, stick a crusty gen 1 engine in the MR2, run your car at Ruapuna, instant 12 sec pass!

Quite a bit of money was spent transplanting the BEAMS 3SGE into the car and getting it to the state that it's in now. Was curious to know what the options were for aftermarket turbo to increase the power.

As the engine, gbox and ecu were retrieved from an SS3 celica (running a hydraulic power steering pump), the current computer setup is not compatible with the EPS setup in the SW20. In other worlds, I am getting TOO much power steering when I don't need it, therefore facing loose steering and unfirm handling when needed at higher speeds.

One of the options were to get a LINK computer compatible to combat this issue. If I was to go down that road, I would of course want to buy a computer that is future-proof for BEAMS turbo potentially, hence why the interest in doing so.

The EHPS runs completely independant to the engine ECU, if I recall.

I dont think it even references the speedo signal, as I've driven around with a broken speedo cable and had no PS issues.

[saft]

I know the MRS pump I used has a speed input.

It just reduces the amount of assistance at speed.

It's possible they didnt reconnect the speed input during the swap.

[Dell'Orto]

Where the hell did they manage to fit a PS pump

The power steering controller is activated by the engine ECU and gets it's speed signal from the ECU as well - On Gen2 ECU's the two pins are side by side.

Not sure on Gen2+'s since they don't have a mechanical speedo sender. The controller may get it's speed signal directly from the dash on them.

There are a few aftermarket controllers for the system so you don't have to stick to stock electronics if you don't want to/are retrofitting.
