Road To 500HP SAAB: T5 Piston & Rods 

I did few similar setups but using the Block of the B234 E/L/R and the B234 Head gasket. The B234 head gasket is way more tolerant. One of these engines is my daily NG900 with 150000 km since the build. For the hydraulic tappets, I start with pressing them to extract the old oil, dump them in cleaning fluid for 24 hours to completely dissolve the old oil and press them with my thumb in an oil can to inset some oil into as a priming lube. I prefer to assemble the camshafts after the cylinder head is tightened to the block, thus not risking the valves. Also, the best "stock" camshafts to use are the B204 I/L / B234 E/L/R. The T7 engine behaves much smoother with them. I always delete the balance shafts. Their contribution to the engine is so small, they consume power and are very sensitive.

Thumbs up as always. Again, great ref. Vid. Keep going, you are doing great! 👍🏻

I got a 2001 9-5 aero. Thank you for sharing your experience with this build. All your videos are great looking forward to the new Ng Saab build your doing.

Great work on the piston balancing, but the conrods really should have been end weighed to balance them. Usually material is taken off the gudgeon pin/small end as well as the big end. This is because the small end sits inside the piston and it doesn’t matter how balanced your pistons are, if your small ends are all different weights the engine can’t be balanced.

Great video packed with good tips Really enjoying this....thankyou

great project nice work 💪🏼

Lifters Need to be heated (softens the tar/oil ) then sqeeze them in a Vise (carefully) the heated oil dribbles out like water...and they begin to be freed up. Follow by an overnight immersion in Laquer thinners to Fully dissolve the crap in the lifter's check valves.

Great work sir Thank to you videos and some other le I did my head gasket on my 05 9-5 aero God bleeds you

excited

Alltid lika pedagogisk grymma videos 👌👌

I have the same setup in my 9-5. But I still need a bigger snail than 21T :D

Hi, good work with the build! I have a question about the pistons. Did you use the pistons from a 1994-98 turbo or a 1991-93 turbo? I got myself pistons from 1991 B234L and I am wondering if I should use them in my 9-5 build.

I've always wanted to test out b202 pistrons and Rods on b205 engine. They are huge! Compare b202 rod to the b204 :D

3/07/24 06:38 BCS Mx. Can these procedures improve B34 balance shaft 1997 9000CS?

Did you make sure the cam clamp bolts were in the right position? Some of the bolts have holes to weep oil.

Hi jonas, so 1.1mm off the t5 pistons and no issues? What gasket are you using with that combination? Im in process of building my 2002 93 coupe. Bottomend has decided it wants to leave the chat 😂 and destroyed the main caps of the b205 block. So plan is to either put a complete t5 234 (rebuilt engine) with gt3076r. Or the other case is b234 block pistons rods and crank and t7 head.

Watching you smash the tappet (lifter) made me cringe. They should be disassembled to be properly cleaned. The orifice is so small, you'll never get the carbon buildup to come back out of the hole. Best method to clean the tappets and disassembly that I've found: Using an air nozzle, inject air into the tappet if it has lost its hydraulic pressure. Take a small strap wrench and wrap the tappet. Find a block of wood and drill a pocket in it that will allow the valve to pop out. Smack the tappet onto the block of wood fairly hard until the 3 pieces of the valve come out (casing, valve & spring). Keep adding air into the oil port as necessary to help pop the valve out. Then and only then can you get these things clean.

Intressant video som vanligt! Hur viktigt är det med balanseringen vid trimning och hur märkbart är det?

Hi body!! Se can you build my Saab to 350hp?

Spännade 😉

Jonas, are the t5 pistons necessary if one does not aim for more than 350hp? Much respect for your videos, just what a driveway mechanic like myself needs! Keep up the good work!

hi jonas, i would like to make a present for the yellow car. is it possible?

Tja Jonas! Vart ifrån köper/hittar du dina delar? T.ex. T5 kolvar o stakar

Did I hear you say 50nm for the cam caps 🤔🤔🤔 I'm sure you said 15nm though

👀🍿🍿👍👍👍

If im gonna install t5 piston and rods, can I use a t5 head gasket on a t7 motor instead of shaving 1.1 mm off the top of the t5 piston?

Jag har en volvo s60, men gillar detta skarpt ändå :-)

Hej, varför skulle du behöva ta ur den gamla oljan ur tryckarna? Om dem funkade innan och du bara sätter i dem igen vid motorrenovering så ser jag inget problem i att gammal olja ligger kvar?😊

All that work, so why not use good forged pistons like Wössner or JE? The T5 pistons are durable but heavy. Good pistons would seem to make a big difference. Factory pistons are the biggest issue with Saab engines.

Nice job! Anower whay to balance a connection rods. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QLpiF0E0EJU.html. usualy in the big end is biger mass diference, but on my saab engine in small end of connection rods I found wheight diference 3g. Tip for assembling moving parts: use liqui-moly visco-stabil or similar product, for lubricating moving parts it ensures better lubricating for engine when it starting for a first time. Till engine will reach corect oil pressure.

Have now 260hp

det är inte lämpligt att montera tryckarna torra, när du väl tömt dom ska du låta dom ligga i oljebad en stund. denna motor kommer väsnas väldigt mkt och kan ev tom haverera. det lättaste sättet att rengöra tryckarna är att slå isär dom (görs mot en träskiva)

Längden på stakarna är inte samma på B234 och B235. B234 har ett CC på 147mm och B235 har ett CC på 153mm. 😊
