Car is still working perfectly! The first version of the engine was built 22 years ago.. time flies... I've done some additional mods to the car such as replacing the TO3/4 with Holser HX35 Super and larger intercooler. I'm still running 1,4 bar boost and with the Holset i feel having more power with the same boost. Now the waste gate seems to be stuck and im running 1,7 bar and having lot of power. I havend done any long pullo with that booster but seems working fine.. so far... When I drive the car I feel that I'm 18 again as you can see from the videos 20240731_103517.mp4 20230722_193518.mp4

Just bought an Outlander turbo with a 4G63T engine..

You mean internal engine mods? Here is an old list of the modifications made: - Volvo 2,1l Turbo (B21ET) 92,5mm Mahle pistons. (Pistons are lowered so that they come ~1mm over the block level at TDC - Block machined for those pistons - Lightened Saab 900 Turbo rods (Any saab with B or H engine (2L) from 75-> 90's, 99 and 900 model). Grinding the crankshaft to the right bearing size is needed - Grinded Dans cam + lash caps - Ported head - Head casket with separate "rings" from http://www.navalinea....it/home_eg.htm They know N9T casket since I've sent one used casket there as a model. I've ordered several caskets from them.. to V-M as well - Garrett T03/4, comp. wheel 60/86 mm, exh. 65/76 mm, A/r .8. The turbo works just perfectly in the engine! Full 1,4 bar boost is already at 3000 rpm and it creates sensitivily boost with smaller rpm's as well. Way better than the previous TO3/4... - Big front mounted cooler - 3"/2,5" exhaus with one muffler - 465ml/min Bosch injectors - Lightened Flywheel - Eaton clutch set with 4 piece? sinter clutch - Vems Round Wideband lambda&EGT (EGT sensor not installed) - Megasquirt MSII (msq file can be sent if someone needs) - Ford wasted spark system (can be found from Sierra, Escort, Mondeo, Fiesta etc.) - Ford Sierra Cosworth fuel pressure regulator -Trottle position sensor changed (cant remember eather the car or the code. If needed I'll check) - 18-1 trigger wheel with Honeywell hall sensor - Ford Sierra Cosworth MAT sensor - 50mm dump valve - "Colder" spark plugs (Bosch heat rate 6) Those are the mods that quicly comes to my mind.. There are probably hundreds of smaller mods that are not listed but I'll try add them as well when they come to my mind... -Tama

Unfortunately I have had some clutch problems and I didnt go to the dyno yet.. the clutch slips only with the 4th and 5th gear... maybe next summer.. The turbo is now Holset HX 40 Super and the boost is 1.3-1.45 bar

Here are some photos from my car. Someday I will make a full photo book and upload some more photos here as well... -Tama

Thanks guys! The rims are 4x100 and they are fitted by using custom made adapters. Adapters are mounted to the original hub and they are 25 mm thick. The wheels are 16" and 7,5" wide in front with ET38 and 9" wide with ET20. The rear wheel is REALLY close to the rear fender so I might need to take few millimeter from the adapter... The clutch only slips in full throttle and only with 4th and 5th gears.. With 3rd the wheels start to slip, no the clutch especially when wet.. Andre: Yes, In Finland we use winter tires because we get heavy snow during the winter.. Usually the winter months are from November to April.. I used to drive the in the wintertime as well but now a days I drive it only in summer time to prevent rusting.. Bean: Let me know if you need something information! I will give you all my megasquirt setups if needed... And of course for everyone else as well.. just ask.. -Tama

New rims... The car has been working quite well now for more than two years with 1,5 bar boost so apparently I've done something right when building and tuning the engine.. The only problem is that I have a oil leak in the énd of the crank shaft or at the gearbox resulting to make the clutch slip with the 4th and 5th gears. The slipping appears only once in a while which makes it weard... No I tried "thicker" engine oil and it seems to work bit better.. -Tama

Sorry about the bad pictures. Pistons are concaved and I made spots for the valves as well so that they dont hit the piston. I ment that when the pistons are in their most upper position they come a bit (~1mm) over the block level. hmm.. cant tell it better.. The idea is to reduce the pressure from the head caskets down side.

Hello Rabin, Creating an album sounds good! How do I send my photos to you? I could probably upload them to your server since I dont have any servers myself? I'm sorry to say that I dont have many detailed pictures from the newest engine. I'll check and send you whatever I have. I have plenty of pictures from the engine from past years but the setup has been different.. -Tama

I've had problems with both piston rings and pistons... Those where the main reason for changing to Volvos pistons. -Tama

I cant remember the exact size of the bearings. My crankshaft was already grinded once before so I had to take some oversized bearings. There are no problems to fit Saab bearings to 505 crankshaft. Grinding the crankshaft is enough. Thanks for V-M about the more detailed information about those rods! -Tama

Hello Rabin I used saab rod bearings. They fit to 505 crankshaft easily. and those rods fit straight to volvos pistons. I never calculated the exact compression ratio but I assume its about 8.1 -Tama
