I have a question for all you guys that may or may not have done a big block nitrous to big block turbo conversion.
I have my car at a well known chassis shop right now and want to have the following list of mods done while its there.
Mount BBF to mate up to the powerglide that we already have mounted in the car (This includes removing the front motor plate mounts for the sbf that was in the car and replacing with mounts for BBF front motor plate. I supplied both the motor and mid plates)
Build 2 14" Stainless headers and mount 2 Precision PT88 Turbos
Build 3" Mild Steel Down Pipes with side exit aluminum pipes as shown in the rendering below. This will require notching the factory fire wall to allow for side exit exhaust too.
Supply all stainless and mild steel for headers and downpipes plus labor to build the headers.
Supply all V-Band Clamps and Flanges that I didn't take with me when I dropped the car off at their shop.
Scale and Set-up car that is already built and was almost race ready with the SBF with the exception of collant system plumbing and wiring both of which I will be doing myself.
I have also already done the complete cold side aluminum pipe work and have supplied both turbos, both wastegates, bov's, stainless header flanges, and a few of the V-Band clamps and flanges. I will also be providing all the motor parts including the aluminum doghouse/elbow as well as doing the EFI intake conversion.
I have been provided about 4 different quotes by different shops and builders and want to see who is closer to being fair on the prices that were quoted to me. I was told by all the shops that the job could take between 40-100 hours depending on which one did the work.
Thanks in advance for any numbers that you guys can provide for me to help me decide which way I need to go. I have a partner in this project too and want a top quality job but I don't want him to think I am trying to price gouge him on our deal either. The prices that have been quoted to me range anywhere from $3800 all the way up to a little over $8000 forthe complete job so you can see where my concern comes into play on this deal.
I WILL NOT go into the names of any of the shops and I'm not trying to to make anyone sound bad. I just want an honest opinion on what a job like this should cost. I'm friends with every one of the shop owners and would trust any of them with this job but we know what we were planning to spend and some of the quotes seemed a little over priced IMO. Maybe it's just me and if so, I will bite the bullet and go with the shop that I feel is the best even if they are the most expensive. I will admit that I am also seriously considering sticking another big inch nitrous motor in the car and calling it a day. We could be up and running and in no time that way but I feel the twin turbo combo will be much more competitive in these tough heads up classes.
