Can a throttle body from a supercharged engine be used on a regular Crossfire with a auto transmission?

 

Yes, that is normally called a 74 MM upgrade.
The NA ( regular ) crossfire TB is 68 MM.

 

Thanks . Found a 77mm. Wanted to make sure before I buy it

 

74 mm, NOT 77 mm !!!!!

 

Its a reworked and modified 74.

 

If the bore that it feeds is 74 mm then you are wasting your time, also you should add a 74 mm MAF or you are wasting your time. Air should flow through a constant diameter bore or you get turbulence which is counter productive.

 

Thanks for the info. Ill rethink my ideas.

 

So I found a donor convertible. Besides the TBI and MAF is there anything else that I should get?

 

Yes, a tune from Eurocharged .

 

 

thanks. Found one in Fairfield.

The search engine on this forum is a wonderful tool; Like most tools, if and when used properly, prevents a lot of verbal chatter.

 

Don't forget to use your original sensor in the housing (the MAF housing). Also, trim out the baffles and screen in the curved intake below the MAF and above the TB. Good luck!

Keep your old TB close by, most of the ones that were modified make the car run radical,,

 

I think that is not quite true, mine and many others ran as if there was no mods done, a few had to do a few runs before irate settled in and one or two had to do a few hundred miles before it settled down. Odd but that was what l recall.

 

How was yours modified ?
I just installed an unmodified 74 mm and had no issues at all.

 

I used a 74 mm TB, a 74 mm MAF using the old sensor, the larger two piece engine cover with K&N filters and the larger intake tubes that fitted the engine cover.
I did not remove baffles or screens, why bother as any increase in power would be unnoticeable. HP at the rear wheels would about 190 to 195 at best.
A year later I got the SRT. I

 

Would you happen to know the OEM number for the SRT throttle body? I've seen too many on Ebay. Thanks for the info
