2) You don't need an AEM to run only 650rwhp. 3) If you're getting an AEM 100% for sure (for whatever reason), then get it installed and running perfectly with the oem twins first. Then put on the 100% complete fuel system and get that working with the AEM. After that put on the turbo kit. If you make all of the changes at once, among other things troubleshooting will be a nightmare. You can run 650rwhp just fine with the oem maf and a simple 'piggyback' fuel controller. If anything, there's too much on your list already, other than the need for wider rims and tires to handle the additional horsepower (unless you want to just sit there spinning instead of going fast). Oh, the oem clutch won't handle 650rwhp. Let me know if you have any questions about clutch upgrades.

When I purchased the car, it already had new injectors installed.
I guess the reason I wanted that turbo was because of the quick spool valve. I already have the AEM Fuel Management System I didn't realize I didn't have to get a standalone for 650whp. I am currently running a Southbend Stage 3 clutch. So then if I want to do 650whp, should I go with a 67mm turbo then like in the kit you sent me? http://www.spracingonline.com/store/...93-98_Supra/28 With that kit I will have to also buy a full fuel system then? Can you send me a link to a good system along with anything else I might need? |

As far as I know, it just has fuel injectors and a fuel rail upgrade. So should I just buy the fuel system kit from Sound Performance?
Ok so I will give them a call about a 67mm turbo kit that has the most up to date parts and I will probley just keep the fuel management then to avoid spending 2k more lol. I will have to get back to you on tire width I forget how wide I got but I know I got the widest I could fit. |

I will take a picture once I get home from the Kentucky Derby but if I don't have a second fuel pump, would I just have to install a second pump instead of buying a fuel system? What else I guess would I need to be able to run 650whp through 750cc injectors and fuel rail?
I will let you know as well what size tires and rims I have once I get home. But all together does the 67mm turbo kit from Sound Performace look like a good choice to go with then? If so, what a/r should I go with? .68 or .81? |

Although you can't easily calculate precisely how much boost you can run with a given octane of gasoline, you can get 'in the ballpark' ... after that, it's best to use data logging of your knock sensors to determine the real number. Also recall that octane degrades over time, so you can run more boost with fresh fuel than you can with fuel that's six months old. The real calculations use difficult-to-collect data points like cylinder pressure and the temperature of the metal in the spark plug. Please take a look at this post (above) for a set of approximate boost-to-octane ratios: http://www.toyota-supra.info/forums/102902-post29.html In that chart, you see that pump gas is only 88MON, which is only good for about 15psi. Of course, you'll get more power at 15psi with a 700rwhp turbo than you will with the stock twins. However, above 15psi you need to use the data from your knock sensors to ensure you're not damaging your engine. The only other alternative is to keep raising boost until you blow up an engine (or significantly reduce it's compression/leakdown numbers), and then next time (and $4000 later, including parts and labor) don't run that much boost.

I have been hearing a lot about people putting heat blankets on their turbos, would you recommend doing something like this?
