Thread: series 2 vs series 3

alright, so i need a motor for my car, wired for series ii, i know the series iii is drive by wire and a few other things, but will the series 2 harness mate up to the series 3 motor? if so it would be alot smarter for me to buy a 2004 gtp for a winter car then rip the motor in the spring, opposed to getting a jy motor and having to rebuild for piece of mind

Series III block is the same as the Series II block, in a nutshell.

Why don't you scrap the Sunflower and keep the GTP?

the gtp is **** lol, 113,xxx miles up here in canada is alot, cause salted roads cars rust fast, its burnt orange with black doors... lol, so esentially if i change the throttle linkage i can drop and bolt up and extra 20hp without doing anything? lol

Be original. Keep the Sunfire !

If you bought an 04 GTP, you'd get the newer slightly more efficient blower. Below that, nearly everything is the same long block wise.
You'd swap over exhaust, ac bracket, diff to engine bracket and alt bracket if needed. Keep the aluminum pan and it's much better mount. Use a TB adapter to adapt from Gen V M90 to your current TB driven by a cable.

so basically, i can swap the motor, use my series 2 wiring harness and just put on my TB and it will work?

Throttle body adapters look like this. I sell for $90 including shipping (USA). Canada a little more. PCV works with this adapter.

yup

No, no it's not. It's also the least useful measurement of the condition of a vehicle.

Bill's got you covered with the whole every 3800 SII+ is basically the same thing.

It's never smart to simply rebuild a 3800. Both you and the shop doing the work should understand the implications of the magical 1000 mile motor. Generally speaking, it's around a grand in machine work.

It'd be smarter to buy the GTP for a winter car, and buy a used L36/L26 block for your project. Open it up and comb over it. If there's sludge, send it back for another. Standard had 10 of them for $400 a pop a couple years ago when I needed a motor. The price has likely gone down since then. That is unless you plan on buying another winter car next year.

didnt really mean full rebuild, mainly gaskets, rockers, cam headers, i just aquired a 2005 n/a s3 grand prix, and meh mileage isnt really a factor if ther person had regular maintenance, but we all know how rare that is, i can get a s2 s/c at a jy for $800 from a 2001 gtp, then id just do gaskets and bolt ons and a smaller pulley, now that being said, s2 with gen v blower or s3? what do you guys suggest, and matt you should know that finding a car with 160,xxx km is hard if youre in ontarion, any other province is good because nobody else uses salt on the roads

origional? id rather think of it as different

Being orginal in your own sense , by not following the typical views and opinions of others

you can put the Gen V bllower on a S2 if you want. Just open up the lim a little.

id be origional by maybe doing the same motor build as someone so i know what to follow along with, but different/unsuspecting by having it stuffed into a sunfire

can i not use the s3 blower and lim on the s2? and just run my throttle body with an adapter

Yes you can.

it all bolts up.

thanks guys, this is my first l67 motor so ill be asking LOTS of questions, but thats how i learnt alot about stereos and competitions, and now people come to me, last year in college i did 3 setups in the parking lot in fall/winter haha

are you in ontario? have you seen a car thats like 15 years old winter driven with no undercoat? lol most are pretty hagred

the reason i said rockers cam headers, etc is cause i want a little more hp but no full rebuild, if the rockers are good sure, it would be a good motor to swap and just drive but im looking for a little more than just slam it in and drive
