DIY - How to forged and build a turbo 4a/7a motor

Ok guys for those that want to build there motor to handle boost , i will post everything that needs to be done to have a good built forged motor. this is my build.



1. things you need .

arp rod , main and head bolts - 4agze motor



Cp pistons 4agze rods and ze crank

note: you can not use the crank or rods off the 4ag. on the 7afe only the pistons can be used.

go to Belfab Racing.com they have 7afe forged rods. you will have to use the stock crank.



you can see the two 4afe next to 4agze rod.



time to put the pistons and rods togeather.













Now dropping in the crank and bolt down the main bolts , arp 60 foot lbs









Time for the Head

Note : you can use 4age valves the intake are the same size round but the exhaust are a little bigger , take it to the machine shop to have it worked out.





i am using 4agze exhaust valves , because they are bibber fastair coming in and fast coming out.



Time to drop the pistons in.

Note : Make shore the rings are gapped right for your style







Torque down the rod bults to 40 foot lbs.

turn the crank to do the next set.

Now time for toga oil pump water pump and pulleys























Arp head studs and HKS head gasket.



Note: arp head studs torque down to 60 foot lbs and you will need to grind the first two arp studs so that the camshafts can turn free`ly or you can just put oem head bolts.

















Time to slap on the head , camshaft , cam and timing componets.

Oil fillter adapter and pan.











i put the head togeather to see how it would look.











This is how the adapter and 20v ITB`S were made for me with air box.

























And on the motor looks great.

Motor .



Head . bronze guids , new oem valves and springs valve stems .



or if you want bigger , 4agze valves. arp head studs 4agze.







camshaft work .







Block . stock 4agze pistons , rods and crank not for 7afe motor



pistons- cp, je or stock



rods- stock 4agze, crower rods







bearings . main and rods.







Oil Pump



Toga oil pump







ARP ROD BOLTS TOYOTA 1.6L 4AGE DOHC 4ALC M9 203-6001







ARP MAIN STUDS TOYOTA 1.6L 4AGE 2.0L 3SFE DOHC 203-5403







ARP Head Studs TOYOTA 1.6L 4AGE DOHC 203-4203







the brains



piggyback or standalone if you go piggyback you will need to check valve it or get a 3sgte map boost sencer.



piggyback







Ok guys if anyone ever desides to use the Apexi SAFC 2 on there 7th Gen, corolla 4a or 7a there are 2 ways to do it. First is if your Rolla is Auto you use diagram 1 and the ECU code diagram is T5-C . Now if your corolla is Manuel you use Diagram 2 and the code is T4-b.



1. Auto Tranny , T5-C





2. Manuel Tranny , T4-b



























what you might need to do.











3sgte map







Standalone:

Microtec LT-10

universal or 4age







Megasquirt

Head gasket



HKS metel any size.







Fuel.



pump , mr2, ae86, supra and celica



walbro 255







Injectors. your stock clips



440cc 7mgte supra







3rd gen 460cc RX7







Note: 93-97 corolla are saturated injectors not peak and hold. to tell the difference you would need a ohms meter and if they read under 10 ohms`s they are Peak and hold or if they are over 10 ohms they are saturated .



If you go aftermarket this is the best for the buck you will need the clips to.







If you use the stock fuel regulater you will need this 12.1 FMU







or if you want to get something better , you wont need the FMU







The 3 most important gauges you need to have on your car.



AEM wideband







if you dont have this on you car this is what will happen.







Oil Pressure







Boost/vacuum : Try to get the boost/vac and not just the boost gauge.

It`s just as important to read Vac as it is to read Boost.







Spark Plugs :



it would not be good to use the stock spark plugs on your corolla , in time they can and will melt the tips



this will work great on the car and will fit are motor.



if you dont want to step it down to 6 or 7 down the stock on the wrx will work great









NGK BKR7EIX iridium spark plugs for wrx/sti .

These Iridium plugs are one step colder then stock, which are less prone to detonation at higher boost levels.

Designed specifically for the performance enthusiast. Iridium IX offers extreme ignitability, improved throttle response and superior anti fouling



* Fine Iridium tip ensures high durability and a consistently stable spark

* Iridium alloy has extremely high melting point, perfect for today’s high-tech, high-performance engines

* “Trivalent Metal Plating” has superior anti-corrosion and anti-seizing properties

* Outstanding acceleration, high fuel efficiency and durability

* Ultimate design, technology and performance

Can you say anything other than awesome? Great pictures too!

Great write-up man. I'd love to do this one day but unfortunately I don't have a money tree in my backyard, haha. This guide looks excellent though, the pictures are helpful and basically speak for themselves. Good to know that there's a resource available like this if/when I ever go for the forced induction option. Nice work.
