thanks for sharing this!!All right! Today I have the pleasure of install one of the MHI turbo , here some pics vs OEM , enjoy!
The turbo is noticeable bigger I mean wheels in person vs OEM , on the pictures no that noticeable.
Well that depends , usually I take around hour and 45 minutes to remove the turbo , depending on which mods you have installed , some aftermarket parts such as downpipe could have the bolts more difficult to remove than other etc it has oem downpipe and turbo shields of it just a blanket etc. You need to remove : intake inlet pipe , downpipe , top bar support ( on top of the radiator) and then you will have acces to the turbo . Then you can remove all the bolts from the exhaust manifold, turbo bracket ( underneath of the turbo ) oil line on top and the bottom , vacune and boost line ( bov, and vac line ) and for last one the water line , that is messy soon as you remove that line the coolant start to leaking, you need to get ready a plug for it. Then you can swap the turbo and reverse the steps , just make sure to never spins the turbine with your hands , cover exhaust manifold exit , intercooler hose and turbo inlet housing for prevent any coolant or any particles goes in . And add oil to the turbo before to plug the feeding oil line .
Great! Thanks I’ve done about 4 downpipe installs so I assumed it was only maybe another 20 mins worth of bolts to get the turbo off!
You mentioned you do your own tuning. Have you finished tuning this turbo yet? I installed mine and still data logging. What PSI have you found you’ve been able to keep it at from mid 3k to redline consistently?
Nice! I saw your post , I installed this turbo in another R , but I really love what I saw on the logs , so ordered one for myself. I haven’t Dyno tuned his car yet , I did a street tune , I saw 25 psi midrange and it keep it up to top end 26 psi peak , but I didn’t pushed the hpfp that much , I kept it in 95% max , but i saw 4.5 to 4.2mm max at top end on the turbo wste gate , it means this turbo was laughing all the time compared to oem , oem was at 2.35 mm mid range 26 psi and 1.1 mm top end , at 23 psi , it means it was already maxed out . Course it depending on which intercooler has installed piping etc , bigger intercooler more hard work the turbo . When I get mine I will post more info regarding tuning . I didn’t wanted to push the turbo at middle range , I had fuel but without Dyno is no real reference where the torque is at .
Right on, I did not do a fuel system. I really wanted to see what a true drop in turbo would do for the car.
Understand, but you actually for make more power you need more boost or change the advance timing , if you going for the route of tunning the advance timing you will need another fuel , more octane , add meth or ethanol. The easy way to achieve more power is adding more boost , specially at top end is were the oem turbo lacks . Depending on the Dyno , but I’ve seen around 405~410 whp on oem fuel system without meth or ethanol, pump 93 octane aftermarket turbo on a heavy roll Dyno , probably hub Dyno you can see bigger numbers .
