Just bought a 87 supra no power in boost

DJ 2501 · 08-21-2009, 12:57 AM

Hello everyone I just registered and just got a supra today. Im very excited.

I traded my 92 civic for this beast. Has some mods hks hg and bov.

Something weird is going on though and being new to supras I need some help. First thing is the cel is on, I know how to pull the codes but can find any code lists to match them up to.

Second thing is the turbo spools fine and blows off and build pressure but when the boost kicks in the car bogs down and almost decelerates. Anyone have any idea as to what this could be?

I was heavy into honda's but its time to mod some real cars for once. I look forward to working on this car and learning and helping out around here.

when you jump in the diagnostics T and E1

it'll blink your codes. codes are double digits

btw there is no code 11. you should try again

Its def 2 longs and no shorts so im assuming it would have to be a code 11

did you try clearing it and then driving it and trying again?

No havent cleared the codes. On hondas you could do this by pulling the ecu fuse for 20 seconds. What is the process for supras?

i cant remember off the top of my head.. but all i do is disconnect the negative of the battery for 20 secs.

You can also pull the EFI fuse for about 30 seconds or so.... I always wait a couple minutes to make sure it's cleared
