increase HP in a I6 200ci

6T6coupe your correct about the chassis, I wasn't sure how much I should talk about this in this thread since the title of the thread is about increasing HP.

As far as what I am going to do to the chassis I don't know yet. I probably wont have the car striped down to the frame for another couple of months then I will start the rebuild process and restrengthen the existing frame as well as add additional supports. If you have any recommendations about chassis upgrades I will listen.

Brakes who needs stinking brakes! Actually with the increased HP I didn't think the 4 lug front end or the back axle would be able to handle the HP so they will be replaced with a new back axle and front end with disc brakes. Again any recommendations will be considered.

As far as tranny goes I wanted to switch over to a manual transmission so the C-4 is out. I have not made my final decision on a T-5 or the Tremec 3550 as of yet. I was going to try and find some gear ratios for each and see which has the best stock setup.

In regards to the radiator I was planning on switching over to a 3 row instead of the 4 row. I would like to keep somewhat warm come winter time.

I was planning on creating some new threads regarding each of these issues as well as others like suspension several weeks before I get to each stage of the rebuild process to give me the time to do some final research on the specifics of each. As well as find out how much fabrication I will have to do with each option.

Any other recommendations will be considered.

Thanks again everyone for the help

66Runt, does the T5z bolt straight onto the I6 200ci or do you have to get a new bell?

Dejavu, I understand that the chassis will need to be upgraded, I have plans to stiff up the entire chassis with a tubular support system. Doing whatever I can to keep it concealed within the body and unseen because I want to keep the car looking stock on the outside. As to what I am going to do exactly I dont know, I am waiting to get the car stripped down before my final decision. My father as an endless supply of tubing, so it will be as light and strong as possible. A couple of my friend have built drag cars and trucks, so with their help I should be able to firm up the chassis as will as develop a suspension and breaking system that will keep the car street legal but strong enough to get the job done. Again I am grateful that you guys are looking out for me and the car and I know that it will take lots of $$$. I didn't know how much of this info I needed to share up front since I was looking for info on how to beef up HP in this thread. But like I said earlier I would like some more opinions on the matter mainly because my friends want to try some new things out on my car and I dont know if I really want to give them free rain. So if anyone has pics or descriptions of what they have done to their car I would love to see and hear about them. This project for me at least will most likely take 2 years to complete because I wont be able to work on it more than 1 night a week and maybe every other weekend. I work about 65 hours a week and my wife said that I she would like to see me during the day more than once a week. Thats why it will be such a long project.

I am going to be putting up forms for a concete floor in one of my barns (40' wide x 28' deep) that I will use as a shop and I am wanting to put a car lift in one of the four bays. Does anyone know if they need any type of footing under them to support the wieght? And for that matter what brand of lift you would suggest?

Being that the block is only 200ci stock I didnt think I would be able to reach the 400 hp range. Maybe if I had a 250ci that could be possible but like but like 65shelbyclone said whats the upper limit? Mike from FSPP would probably know if its possible.
