List for low boost beams turbo

[mr2nv]

Might still go with a supercharger but I'd like to gather some knowledge and a parts list on what it would take to make a reliable low boost beams turbo. The car is mainly used for autocross so I'm looking for a fast spooling turbo. To start, I'm looking at maybe 250-280hp on pump fuel. Fully realize tuning is the key but still need to know what I'm dealing with in parts.

Turbo:
garrett gt2871r with smaller turbine housing
any other suggestions on small, fast spooling turbos that would compliment the beams? ct20b?

Exhaust Manifold:
Does the gen 3 or gen 4 turbo manifold bolt up to the beams head? Would I need a custom manifold made? Don't know much about turbos...adapters to bolt on the turbo?

Intercooler:
Would a stock intercooler be fine for less than 10lbs of boost?

ECU:
What non-expensive ecu setup should I be looking at that can at least control vvti?

Fuel:
Do I need bigger injectors? bigger pump?

Internals:
Do I need forged rods at a minimum? can I use stock gen 3 turbo rods? do I really need to lower the compression for such low boost? what pistons?

Anything else I'm missing? And no, I'm not swapping in a turbo engine at this stage.

Thats a pretty good turbo for the power you're looking at.

You can use a Blacktop BEAMS turbo manifold.

Neither gen3 or gen4 fit on the BEAMS.

Stock intercooler would be fine.

Power FC

Yes to both

This is debatable as no one has any real documented info on turbocharging a BEAMS. Relatively speaking Toyota blocks are not the strongest but I personally think that BEAMS should hold 10 psi on stock internals. You can get aftermarket headgasket from apexi that thicker and thatll help lower compression a little.

you'd need to be very carefull when doing that unless someone knows of one that does work. Blacktop manifolds are setup for a north-south engine, which is also dead upright not tilted like the mr2, and will either be a top mount turbo, in which case it could end up poking out the top of your engine hood and interfering with strut braces etc, or if its a lower mount, cause of the tilt of the engine it might be in your firewall. Lastly the inlet/outlet are usually facing the opposite direction, might not be a problem if you can use it that way or flip the turbo around. Also if you have your altenator in the celica position this would clash with the turbo inlet.

The toyota ct26/ct20b wouldnt be very complimentary to a beams as the twin entry becomes a restriction with lots of exhaust flow at high revs. I think with a good tune compression would be less of an issue than pistons being lightweight na jobs which wont stand up to the heat for all that long, so if you can celica_ra45 can supply pistons (you cant use 3s-gte pistons) and i beleive they work with gen 2 3s-gte rods which will be strong enough for the power your looking at. The beams already has a metal head gasket so should be ok.

From some more reading it sounds like I'm going to need a custom turbo manifold made. Any suggestions on who could do this? what kind of adapter would i need to mate it to a gt2871r?

For pistons, am I looking for forged pistons but same compression(valve reliefs) that can use stock turbo rods?

Which injectors? Or are the stock ones good enough when tuned and controlled by a stand alone EMS?

Which Power FC do I get? I've seen a few for sale(gen3 3sgte i think) and I know there has been experimentation with using the 1zz pfc. It allows you to control vvti? And I guess I'd need the boost control module? Or do I get the one for the altezza sxe10?

I think there is enough room in a MR2 engine bay to make the Blacktop manifold work. Plus the manifold is straight its not angle only the position of the motor itself is angled. If i remember correctly the turbo manifolds are mid/lower mount. The inlet/outlet would be something to be addressed.

It will be alot easier to make the Blacktop turbo manifold work on Redtop BEAMS. Someone people will say its cheaper to get a custom one made but 9/10 those custom made log manifolds are complete crap. They tend to fall apart and crack fairly quickly simply because lots of people say they have good welding skills but the truth is that there are very few actual good welders out there. If you do find one they will charge alot.

Nothing ECU wise from any 3SGTE will work. For the PowerFC the only one proven to work is the 1ZZ though Brashboy sells a modified SXE10 PowerFC specifically for the Redtop BEAMS but it costs 2k.

Injectors I would look at a 400cc size injector for the power you are looking at.

Contact phoenix on pistons I believe he found some pistons that will work. Or again you can use Blacktop low CR pistions as the blocks are almost the exact same. Which is why i think the BEAMS can hold boost on stock internals.

Well, I called full race and they said they can't make me a one off beams turbo manifold. Wasn't the blacktop NA as well? Did toyota make the blacktop with a turbo? Can you site any sources for this blacktop turbo manifold? Links?

So, I buy a 1zz power FC....then what? Isn't the altezza power fc for the 3sge closer to what I need than for a different engine?

[Servin]

Yes it came NA but lots of companies in Japan made Turbo kits for it along with roots type superchargers. No Toyota never made a BEAMS turbo, regardless of color. Ill dig some up for you. Also something I have left out, is that you will need a custom downpipe made but you need that anyways.

Well you buy and then tune it of course! Actually you have to do a little re-wiring but more on that below. No because the 3SGE/3SGTE doesnt have VVTi which why we use the 1ZZ ECU as it supports VVTi control. Also it uses VVTi solely on the intake cam whereas the Blacktop uses VVTi on both cams making tuning the ECU alot harder since we dont have VVTi on the exhaust side. Read up on that thread it explains it in more depth and you'll get a better understanding.

Check out this thread, it might answer some of your questions.

I am under the assumption the blacktop manifold won't fit, I think the ports are off. I will see if I can't find the thread that has that info in it.

[Servin]

Nope the blacktop manifolds bolt right up, intake and exhaust. At least Im sure I saw Glen post that or Roman. It was Roman.

It's also possible that gen 4 3SGTE bits (Caldina GTT engine) Will fit on too, but I cant confirm.

Also some Altezza manifolds are also top mount, I said earlier they were low mount. I saw a couple of pictures of top mount manifolds. And I will get links for a manifold soon.
