Odd question, not sure if anyone here will know.

So I have an (originally) N/A L36 in my 2000 bonneville that is now topswapped running a pnp gen 3 blower, and e85 on a 3.8 pulley, looking to get some more mods done so I can get down to a smaller pulley... but... almost no one makes headers for the bonnie

and those that do are quite expensive new, and hard to find used

So basically just curious if anyone here had experience with headers in a bonnie and maybe how much modification would have to be done for GP headers to fit in my bonneville? Thanks!! Hope GP headers will fit with a little bit of modifications.. haha

You have bigger injectors for that e85 right?

And to my knowledge the cheap ebay SD headers fit the bonneville but some modidication is needed if I remember right. I thought someone did it recently but I forget who.

Speed daddy headers will fIt fine

Awesome. Excited to make my sle pretty scary! I'll keep you guys updated, you're much more helpful than the guys at the bonnie forums

It'll take a lot to make it scary

Well lets just say my dd is a 2006 wrx thats 337 awhp and 386 awtq... and I run low 11s on street tires. And the bonneville will eventually be in the same neighborhood if I get my way. Haha

AWD > FWD remember that lol

**dsmuts** · 08-15-2013

You'll have to turbo the bonne then

with a turbo on the bonne you'll make much more power than the wrx for way cheaper.

it'll still be slower, though.

Just follow the Clarkson mantra: POWER. SPEEEEEEEEEEEEEEEEEEEEEEEEEEEEED.

Your topswapped? We were discussing to buy my topswap 1 day ago do you still need it?

**SnowTh1ef** · 08-15-2013

I do still need your top swap grimsin. Different project, long story haha. And yeah eventually going to turbo it.

The headers fit. The only modification you have to make is connecting to the exhaust under the car. Because there isn't the same catback flange. That's all.
