Road To 500HP SAAB: T5 Piston & Rods

[@barenekid9695]

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.

[@orenkipnis7058]

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.

[@JonasKakarikas]

Everyone has their own way of tuning 🙏 think im going to keep balancing transmission. Heard some People getting mad vibrations, i dont wanna risk that 👍

[@juancarloslozano3374]

Hello! I'm agreed about the tapets, is what I knew about them. Can you elaborate more about the sensitiveness of the balance shafts?

[@orenkipnis7058]

@@juancarloslozano3374 Balance shaft chain is very small and the balance shafts rotate the speed of the crank shaft. the tension guide and the tensioner itself are smaller than those of the camshaft chain. A torn balance chain may lead to a camshaft chain failure and a total destruction of the engine. A tensioner failure will result in a sudden loss of the oil pressure. A balance shaft chain which "jumps" n a sprocket will lead to terrible vibrations.

[@vank4205]

@@orenkipnis7058 and the unique function is no have vibrations in the mid range where usually the four cylinder engines have them, but there are many people that delete the balance shafts and no have any appreciable difference. Because, for example, the WIS already said that by under of 1800 rpm the effect of the balance shafts in very small. In low revs is most important the good condition of the engine mounts.

[@vank4205]

In my opinion many of ghe people that have vibrations is because they don't balance pistons and rods, and they no have the crank and rods bearings in good condition. All these things combined produce vibrations.

[@Soulfirer]

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

[@raverlife3413]

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.

[@tgvic2078]

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.

[@TheSaab04]

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

[@mafel2352]

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.

[@caractacusbrittania7442]

[@kj-un5lx]

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.

[@JonasKakarikas]

Take 1,2mm of the top and then you are safe. T7 Steel gasket 👌

[@phisach3271]

great project nice work 💪🏼

[@Eriken1]

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

[@JonasKakarikas]

Svårt att säga hur mycket det känns och påverkar. Men har man isär allting är det dumt att inte göra det

[@NeBiStR]

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

[@marekukawski202]

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

[@fieldlab4]

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.

[@JonasKakarikas]

T5 works awesome for the price 👌

[@алексейприлипко-с9д]

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

[@Hillfortgaragecustoms]

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

[@chicagoui9299]

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

[@JonasKakarikas]

They are in the exact position where they was before 👍

[@fncvideo1136]

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

[@jstephan03]

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.

[@wudecki]

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!

[@nuggex]

T7 pistons can barely hold 300bhp. 350 will crack them.

[@JonasKakarikas]

Correct, this a good upgrade for future tuning 🙏

[@wudecki]

@@JonasKakarikas @nuggex thank you for the info lads. How about a 300hp daily, will t7 hold that?

[@nuggex]

@@wudecki Probably untill they don't. I wouldn't go beyond Stage 3 (260-270hp) on T7 pistons long term in a daily car. If you want it to keep the shiny bits on the inside that is.

[@JonasKakarikas]

Stage 3 315hp / 440nm on e85 is cool if you Daily it and drive with your head, have a proper intercooler etc. After that it gets pretty rough for them to survive 🙈

[@eriklarsson5917]

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)

[@emilfredriksson9886]

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

[@JonasKakarikas]

Tjena, av någon anledning har jag lyckats få tag i via kontakter, skrotar, Blocket osv varje gång jag har jagat. Skrotar vill dock oftast sälja hela motorer...

[@johanloof2363]

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

[@93_forceboy55]

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?

[@JonasKakarikas]

Yes that should be a possibility, but not recommended

[@93_forceboy55]

Ok so I’ll just do what your doing, also are all t5 turbo piston and rods the same? For example b204l and b234r

[@JonasKakarikas]

No they are not, If you have a 2,0 then you need piston and rods from a 2,0...google to see exact what years are The best etc, 👍

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?😊

[@gnodisen]

För övrigt jättebra videor.👍

Olja är väl något man vill ha ny vid en renovering? Sen är det klart fördelaktigt om lyftaren flexar ner när man monterar kammarna.

Nice job! Anower whay to balance a connection rods. kzbin.info/www/bejne/h33TmnlmepV4gLc. 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.
