Thread: top swap 05 gp

how difficult and what would i need to make my n/a 3800 a s/c 3800. I'm board with stock already. Thanks for any help

Heads, LIM, vac lines, SC, TB, PCM programming, fuel rail, fuel injectors, idler pullies, tensioner, harmonic balancer, and various other small odds and ends.

Some places sell complete packages. Though I don't know they have them for the Series III engines. You'd need the Gen V M90 and I don't know how all that electronic throttle body non-sense would work.

You sure you would need the gen5 s/c? I thought the l26 block was the same as the l67 block, just higher compression because the l26 block is N/A. The l26 block has stronger connecting rods and such.

I was under the assumption that you could swap the lower end of a l67 with a l26 and everything would bolt up, though the only one I've seen had a gen v swap on top of it.

Regardless, if you top swapped the l26, you would have to run a slightly larger pulley compared to everyone else because of the higher compression. You would make more power though.

How easily does a Series III throttle body bolt to the Gen III M90? He can't use a Series II throttle body because of the electronically controlled stuff.

I don't know if the L26 and L32 TBs are interchangeable, nor do I know if you can use the L32 throttle body with your electronics if you top swap. I haven't seen any sites that port Series III TBs that I can remember, but I'm not exactly looking since I have a Series II/III hybrid and my TB is from Series II.

Price it out you might beable to get a non IC'd turbo kit for cheaper, and would be easier to install. GenV's aren't cheap.

thanks for all the input its all a great help. you guys are great on this forum

Doing it with ZZP's SS kit costs like $1k.
