ok im trying to turbocharge my 7afe im making a list of what i need and let me kno if im missing something:

.Turbo-t3/t4
.turbo header
.intercooler 52mm 2" to 2 1/4
.custom downpipe
.toyota supra TT 255iph walbro fuel pump
.vortech 12:1 FMU
.high impendance injectors
.platium spark plugs

if im missing something let me kno.....

*What are you doing to get around not getting boost to the MAP sensor? You either need a 3S-GTE turbo pressure sensor, or a Missing Link bypass valve which is what I'm using. At least, some fish tank check valves will work. I used them for over two years and they worked perfect, contrary to popular belief.

*What about the wastegate? Unless you're running an internal one, you will need one, and a manifold with a flange for it. You need the flange that goes from the exhaust manifold to the pipe which will become a downpipe, and the metal gasket that goes in between the two mating surfaces.

*You need couplings, preferably Purosil, for the intercooler piping, and t-bolt clamps to secure them properly.

*Forget about Bosch Platinum garbage. Use regular NGK V-Power grade 8 spark plugs. They're very cheap, and work the best, so you'll thanks me later.

*Along with the e-Manage unit, to get the most out of the tuning, you need the additional injection harness, ignition harness, boost pressure harness, boost pressure sensor, and the support tool CD with the cable. Well, I could make you a copy of my CD, unless you get an Ultimate. I did my research and the e-Manage Blue is no slouch. My buddy's 2ZZ-GE pumped out 505 WHP using an e-Manage Blue, so the thing works more than great for being a piggyback. Some people that went to the Ultimate claim that they would go back to the Blue. The Ultimate has additional fuel map storage, so you can swap from a street tune to a track tune, and it also has a self-tuning feature to give you a baseline tune, along with other gadgets. For the power goal you're aiming for, the cheaper Blue will work great, and you can get them used on eBay for very cheap, since people think the Ultimate is the holy grail, and they sell their Blue units.

For injectors, you need high impedance 16 ohm ones. Mazda MX-6 Turbo/Ford Probe Turbo injectors are more than enough for 200 WHP. They get that power out of their engines, which are bigger than ours. You'll need to cut the 7A-FE harnesses and solder the other ones, but it's too easy. I did it and I'm fine and dandy.

Intercooler? Hmmm, this is a very custom thing. There are a thousand and one ways to route intercooler piping. I got mine redone two times after the first time, which were a complete crush bend disaster.

You need a boost controller if you're planning to boost higher than the stock wastegate setting. I've used a TurboXS manual, a Turbonetics manual, a GReddy Profec-B Spec-2 and my actual Blitz Dual SBC Spec-S. The latter two work similar and are great. You can adjust boost response. It works great. You need an EGT gauge. Forget Autometer pyrometers. They respond too slow. Get a GReddy peak and hold unit or an HKS peak and hold unit. You can replay how high the EGTs went. It helps you out. They respond very fast, too. You need a boost gauge to know how you're boosting. An electronic boost controller will tell you that, but get a boost gauge so you have two different sources. If one fails, you have the other one as back-up. My Autometer Phantom boost gauge is dead-on accurate with the Blitz EBC.

How are you planning to control that Walbro fuel pump? You need an adjustable 1:1 fuel pressure regulator, like an SX, or Aeromotive unit, and a fuel gauge to know the fuel pressure. You need braided fuel lines for the feed and return, and required fittings to connect all that stuff properly and have a reliable fuel system. Don't trust rubber hoses. Remember this will not be a puny stock fuel pump on stock injectors. Fuel pressure will be considerably higher. Better be safe than sorry. You'll spend a lot of money, but the stuff will last, and you can use it on another car later on in life. Two birds killed with one stone.

I did my homework years, and was the second 7A-FTE since Celica.net, so I know what the engine likes and what it dislikes. I've spent a lot of money, more than most, but I could reuse this stuff or sell it. If you skimp and go the "easy" route, you'll lose in the end. Trust me. Many people did and they broke the engine and quit the project.


I'm really nauseous, so I'm going to bed. I'm feeling dizzy and sick. I'll keep going tomorrow, unless somebody takes over.
