how much HP can the factory coil packs hold before needing to be upgraded or wont i need to?

also what brand fuel pump do you recomend to get to pump the juice to the 1jz?

thanks

Depends on the condition of them, if there running fine now they should handle plenty.
I know of stock coilpacks that were cracked then glued up supporting well over 400rwkw

I don't see how power will damage the coil packs.
From coil pack point of view power is irrelevant - it is there to spark not to push pistons

. Obviously there is the compression which might effect the spark but that is another issue completely.

it's the other way around!!! the coil packs can damage the top end power.

this would probably be around the 400kw mark as mentioned above.
I see nyle Buckley has upgraded the coils in jos drag corona , he used to have a set of diamante v6 coil packs but has since swapped out to 6 bosch individual coil packs.

how much power does john (audi man) make now? last time i checked it was something in the order of 450rwkw, and that's using stock coil packs with epoxy. as for fuel pump, get whatever your heart desires, i've been through 3 bosch pumps, they worked great till they broke (which can be embarrassing if you're trying to do a ¼ mile) , now i'm using a walbro, and its fine too.

Stock packs in good condition can take over 1000hp as the yanks have prooven many times.

I know of several people with >400wkw and no ignition system changes.

He was making 488rwkw a while ago, but hes upgraded since then
Think hes changed to a better condition set of coilpacks, as I have a couple of his old ones.
He made the 488 on his worst 6 coil[acks that he glued up for an experiment to see how well it worked

So the gluing them up worked? were the sparks 'leaking'? I've heard some use epoxy glue or some shhit

Yep, get them nice and dry an use epoxy on them. You could also use a thin, very high temp resistant heat wrap around them after glue to be sure...

I used epoxy resin on the set in mine which were making the car miss like a pig even without load/boost (had no intercooler piping hooked up
Glued them up, and pulled top gear in the driveway on the spot

no misses at all
