Re: auto to manual

So much work that it's cheaper AND easier to sell your car and buy a 5 speed V8 car to swap your 400 in to.

The difference:

Engine, transmission, crossmember, pedals, linkage/hydraulics, speedometer drive, neutral start/clutch start switch, transmission tunnel shifter hole, shifter, console shifter plate/boot

This also doesn't take into account ECM, but you're probably not doing that anyway. It's best if you buy a complete change over kit. The last one I bought from this site for 600 bucks. I have a V6 car but it's going V8.

you need to replace the flexplate and torque converter with a clutch and flywheel, bolt the manual trans up, cut the shifter hole <<go to the junkyard and bring a piece of cardboard and a sharpie and trace the hole.
and a few other basic things. it's not too bad :]

Re: auto to manual

Maybe ignorance is spreading around!

He is going V6 to V8, as well as auto to std. I doubt you've done that in a third gen or you wouldn't be taling about how easy it is!

There is absolutely nothing re-usable in this swap. If he starts with a V8 car, he can do the swap as you describe.

There's nothing horrible about what I think. I have the benefit of experience on my side, WITH THESE CARS IN PARTICULAR. I have done this, going from 4 cyl to V8, and it takes a lot of time unless it's a hack job.

lol you don't know hard until you but an lsx in a porsche 944 ( such as I have done)
I've done v6-v8 swaps in f-bodys.
i've also done auto - manual swaps in f-bodys.
it takes time. EVERYTHING does.
So a combination of the two isnt difficult if you've done it before.
so dont automatically think because i'm new to this forum i have no idea what i'm talking about.

To Boostin'xr4:

Ditto the been there done that. That's why you shouldn't start off flaming me. I also have the benefit of much experience and many unorthodox engine swaps.

You could just offer your advice instead of taking a swipe at me accross digital space. THAT'S what shows you're new to the forum; bench racing and fixing cars in cyberspace are very different than taking your time in a garage. Some people can't afford that time and it translates into difficult.

It's not difficult to build a skyscraper, but it takes time and money that most people don't want to dedicate...

There are 2 things wrong with this idea...keeping you tranny.
First, Im not 100% but, the tranny bolt pattern on the 2.8 should be different that the bolt pattern on a 6.6.
Second, even if you made an adapter plate, the 2.8 tranny probubly wont be able to handle the power of a 6.6.
If you are going to spend a couple years to make something like this, do it right. Dont cut corners, especially on somthing as important as your transmission. Good luck with your project.

you are exactly correct grimmcs,that 2.8 tranny isn't going to be worth its weight in scrap tin for a v8 swap.
