Awesome. I have one of the last 9-5s made in '99. The ECU is year 2000. My mechanic said that I already have the Aero inlet pipe on my car (year '00 enhancement). So suppose I must have the updated block.

Green9kAERO i have givin up for the moment aquiring the 9-5... i was thinking about it as a dd for a little while, but everyone interested in my 91 seems to want to trade.... and they dont seem to have anything that sparks my interest. im just gonna keep my 9k and play with it somemore. ill buy the 9-5 later in the year if i sourse a b234 for it.

Red DIC If you were going to fix and build it to sell it, why would you buy performance parts for it, I'd get it up to stock running condition and then unload it on craigslist...

I believe the might have been a rod, piston update in 2000. So your Aero would have had different internals than a '99 9-5. The part numbers for the '99s are probably superseded by the newer style stuff.

StX221 i am 99% sure that on a b235, the internals are 100% identical.
11-06-2007 07:03 PM
9000thomas sorry, thread jacking, but also to make it known, the pistons and rods are different from an aero engine to a lpt engine. The r block has tapered rods and wrist pin collets. Eliminate the balance shaft system. not necessary. Slightly more vibration, but nothing to bad

Green9kAERO im amazed that no one has chopped up the new V6 manifolds and bolted t25s on them for a twin turbo setup.. im sure someone will be doing something like that as these cars get older... such a silly setup to build the turbo into the manafold.
anymore comments on the composition of the engine... it is completely bolt in style upgrade right. will the balence shaft gears and all that bolt to a b234 from a b235... i kno there prone to failure so if i can use the better conditioned gears between the two motors id be happy..

NickTurbo900 I thought the SE was a V6.

Green9kAERO huh, the SE is just styling in a 9-5 but in a 9-3 it gets a td04? thats depressing. i consider the 9-5 to be the better of the 2, but that just seems backwards.
maybe a 200 hp ecu would be sufficiant... but id definatly be interested in a used staged tune.

No and SE is just a styling package in 99..

But I had a stage III tune on my GT17 and it was supposed to be 260HP, but it ran out of breath at about 5K. Yo can soemtimes get a used tuned ECU for liek 350-500 ( I sold mine for 250 and the new owners old ECU) MAybe Deloean will sell my od one to you when he goes to the TD04. You can also get one of those 200 HP Saab ECUs that were sold for 10 bucks at SOC ( required no hardware) for like 100 on line somewhere. Look around on ebay..
11-03-2007 06:45 PM
Green9kAERO wow those are cheaper then i expected...
you almost make it sound as if i could afford to maintain a 9-5...
on the edge about it, i do like the comfort much better then my 91, but it doesnt have the obnoxious styling i like.. doesnt seem like i can source used parts as easy.

its not the hour under the dash im worried about, im scared that all those stupid "pop" pins and such are going to "snap" and stuff wont go in like it came out.

engine swap is old science, i been doing that since i was 12... but the rest is kinda new to me...not use to a car this advanced.

ehh time will tell. Need tobias to come threw with the money for my car so i can get things rolling.

No it is not double pass also it is not bar and plate and does not flow that well, better to upgrade. FMIC can be done pretty cheaply.

OOO the sid dying, that's a reason to be scared???? Your talking about a swap and th estupid SID is a big worry??? Yeah if you can't read the SID you might as well give the car away... or pop th eSID and DIY fix ro spend a whole 100 to get it fixed with lifetime warranty...

ANd the heater box fix, an hour or so under the dash scare you too? and you can always take out the neg camber, the car won't be great in the twisties after that but your tires will last ( of course the will if you rotate every 3-5K oil change that'l work too...
11-03-2007 03:22 PM
Green9kAERO maybe ill get lucky and the turbo was already swapped, maybe the previous owner pocketed up for a gt2871 errr not but its fun to pretend.

yes, i am aware that a t5 b234 would be nessesary.

im pretty certain id throw the b234 in and get everything up to par, then start throwing in the fun parts... so ill be sure to see if the gt17 is smoking or not,

Carl Voice of reason chiming in here; perhaps stating the obvious, but I haven't seen any mention of these important facts in the course of this thread:

1. Make sure the B234 block is out of a 1994-1998 9000, the earlier B234s are physically different and will not fit in the engine bay of a 9-5 or mate to its transmission.

2. 9-5's have a front mount intercooler regardless of being LPT or Aero, it's sandwiched in there and is plenty big.

3. If that GT-17 isn't smoking (haha fat chance), I'm sure a high-mileage 9-5 driver with a smoking GT-17, no interest in seeking out a TD04 and mild tune would be interested.

Green9kAERO well, if i get the car and a b234 block, it would get all new seals and bearings, but keep stock rings and such. dont want to pay for them

but to run a b234 block inmy car i need nothing other then the block correct?

stg3 would mean a real IC, a 3 inch exaust and a real turbo correct.
if the gt17 is still alive would it be worth anything.
Ic would be random front mount off ebay, turbo would be a td04, and 3 inch pipes would be another garage custom job..
then 800 bucks for a tune, thats pretty sickening..but hey, 1400 bucks into more performance doesnt sound too bad, bbut ill be impressed if it would keep up with my 91, let alone take it.
