Hi guys, Does anyone know of a reputable company that will still bore and rebuild crossfire TBI throttle bodys? thanks

 

Maybe contact @Buccaneer he should be able to point you in the right direction.

 

He already did Greg, we had a long conversation about a lot of things today. Unfortunately I don't know anyone that is doing that anymore that I would recommend. Maybe I should get back into that business again huh? Good luck Mike, let me know how you make out.

 

Looks like you are getting back into all your old business dealings
I know someone in Australia who might know someone else in Australia. Haha

 

Now that's funny!

On another note...How's that fire going? Are you guys in danger where you are at?

 

No it’s a big country. We had some fires in Queensland but not like NSW and Victoria. They are the worst bush fires that I can remember. The problem is that the country has been in drought for a long time so everything is very dry. Our rural fire services and local councils generally do back burning in the cooler months so that there is less fuel to burn when it gets hot. They haven’t been able to do much back burning for the last couple of year because it’s so dry and they would be risking starting a big fire.
Our Prim minister is very unpopular at the moment. He took a holiday to Hawaii on the quite even though the bush fires were raging in NSW. His government dismantled our carbon tax system (similar to the one being suggested by some Republicans in your country) so our emissions reduction has stalled. This government is also full of climate change deniers and there are elements in his government trying to blame the Greenies for the fires ie no back burning, but as I explained above it’s not the Greenies that stopped the back burning its the drought.
So the ground is hot and the political situation is hot. I’m certainly no environmentalists I have two V8 road cars, speed boat, go kart, and I just bought a Gen 3 Camaro racing car, but there is no doubt in my mind that the climate has changed. Anyway I normally try and steer away from politics on this form but we have never seen fires like this in Australia. Some places are prone to bush fires but there has been fires in towns that were 150 years old and never had a fire. Many of our winter ski fields have burnt we really have never seen anything like it.

 

Well, that's good and hope you don't see any fires there. I heard we have sent fire fighters from Arizona there to help.

 

yeah that’s true man and aircraft. Fvck only knows why we don’t have more of those water bombers in a country where we expect a certain number of firs every summer.

 

But I feel I have hijacked the thread so back to throttle body boring. If not @Buccaneer then who?

 

There used to be an old school carb shop by me that did boring... maybe you could get lucky and find one of those still around?

 

i did mine at home

 

 

 

See if this place can help

Hope you guys stay safe. We have had similar fires (obviously not to the same scale) in most places I've lived. Every time they happened, it was yelled as a calamity. Politicians talked all their talk, battle lines were drawn, all that stuff. The Botanists and experts were silent, and would only comment on things like "this is the largest fire we've seen to date", other vague non answers. This year, we took a guided hike through an old growth forest, and our guide brought up some very interesting facts. Our forests (yours may be different) were designed around forest fires occurring. Some trees evolved bark that would protect them from most forest fires, so only the brush was cleared out. Some trees evolved seeds that didn't open until they reached hugely hot temperature (meaning a fire had happened and cleared the path for them to grow. It was truly awe inspiring how nature had evolved in such a way that these disasters we saw were just part of their life cycle of their environment.

I don't know anything about the Australian bush ecosystems, just something that I thought was interesting.

Back on topic... what makes the Crossfires special that any machine shop couldn't bore and rebuild the throttle bodies?

 

A lot of places don't want to touch them. For whatever reason... they're simple to me....

 

Yeah we learnt at school that a lot of eucalyptus (gum) trees needed fire much as you described above. Our indigenous people also managed the land for 1000s of years and they did a form of back burning the encouraged new growth etc.

TB boring should be straight forward for any serious carby/race shop. Just need to make sure the ported vacuum port is still functional so you can balance them easily.

 

That’s a nice job. How does it drive. I have a friend that has bored them out quite a long way. The car is very fast but apparently a bit of a pig to drive around town. I was thinking that 50mm might be a good compromise.

 

Are you sure boring out the throttle bodies will do any good? Here's a previous quote from Tom400CFI:

 

the easiest way to tell if if you have vaccum in the manifold at wide open. If you do then you need more. I am not planning on doing mine unless necessary.
