Working on the plan
Put the alternator in the Celica position near the exhaust manifold. Use all factory stock components for that.
This frees up the alternator position for the SC. Make a bracket for the SC where the alternator was. Use the threaded holes on the block that the alternator was mounted on.
Use the alternator belt to drive the SC.
Now i need to add a tensioning wheel as the SC has to be permanant mounted and within 15 degrees horizontal.
Please anyone to help on this . Prefer a standard Toyota part.
The oil to drive the Rotrex will be piped to the oil cooler which will be set up on the right side engine air intake infront of the engine fan.
Question as mine is a N/A that fan only comes on when the engine bay is hot.
Question, in a turbo that fan is in front of the A/A intercooler is the fan always on ? or only on as with the N/A ? Does it suck air into the engine bay or out like the N/A
The resevior that comes with the Rotex and filter will also be near the fan for easy checking and also provide some air movement. The piping will consist of both hose and pipes so as to not look like aftermarket.
Air will come through the std air box but the MAF disconnected. 3 inch pipe will then go from the air box down the left side and behind the engine below the inlet manifold to the SC. The SC has a 3 inch inlet opening.
Then out of the SC to a PWR A/W intercooler. Sausage type. Then to a SUPRA Inline MAF. Then into the Throttle body.
I need a reciculating BOV that goes between the BEFORE AND AFTER the SC as to stop build up of pressure when the TB is closed
Recommendations please.
The A/W intercooler will be plumbed again with pipes and hoses to a front mounted radiator and use a bosch pump. Is this the best pump ?
The wiring for the Supra MAF has to be wired correctly as the pins are a different order.
All the pipes are going to be Flat Black powder coated.
The A/W intercooler will also use threaded holes on the block for support with black silicon connectors where required between the pipes .
The pulley for the SC will be roughly 105 mm but it has to be calculated so as to give me max 8 psi at 7000 rpm and not get the Rotrex to work out of its limits. To do this can anyone tell me the diameter of the pulley on the Crank that runs the alternator ?
Now increase injectors to 440cc . But does the fuel pump need to be changed ?
Finally a Motec 400 to run it and a very good tuner
2zz owners have this set up and all get high HP and claim even with their 11.5 compression 60 HP is well with in its safe limits with stock engine . What do you guys reckon ? They say its all up to the tunning and not pushing it to high. Choose the SC pulley correctly so as to limit the pressure.
Also use a VW wide band O2 sensor.
MAF SHOULD BE BEFORE the TB as it will be the most stable as it will be constant velocity and temp .
Everyone who has put an air pod with the MAF straight after it has changed it to this position due to problems, air pulsating .
They then experinent with smaller pulleys and restrictors on the inlet to the SC so as to increase low end torque without increasing the overall PSI
Have l left anything out ?
Any help would be nice.
