Just like the topic header says…ive been doing alot of searching with no real answer so…anyways i picked up this turbo and i was wondering will this turbo be to laggy for my b20…the turbo is a stage1 turbine…i only plan to run 10-12 pounds
to be specific the set-up is:
JDM b20b (dont know if it is different from a USDM one)
Skunk2 Intake manifold
Stage 1 Crower Cams
2.5 inch charge piping
2.5 DP with DMH performance E-cutout
CC-Fab log manifold (havent gotten it yet)
Garrett T3/To4e 60 Trim Stage one .63 turb .70 comp (from Blaast…thanks Guillaume)
Greddy Profec B Spec 2
Tial Style Wastegate (8 PSI Spring) dumping into atmo
ARC Type NS BOV
Greddy Style Intercooler (28"x6"x2.5")
ARP Headstuds
New oem headgasket
Chipped P28 on Uberdata
So yeah please let me know how well this turbo will perform on this set up…specifically spool time…i want to be full spooling by 4500rpm or less…thanks a bunch
wow i guess that is a pretty decent spool. I dont have a problem with lag though…i think its blown out of proportion anyways…more lag better traction and vice versa. Thanks for the opinions guys keep them coming… :bump:
In my opinion, I think you made a boo-boo. Unless you extend your rpms beyond the factory redline of the b20 and use a higher psi level the turbo will actually be performing badly…given its true capabilities. Basically ur lookin at a boost range between 4.5k-5.8,5.9(I forget exactly the stock redline). As you can see that’s a little over 1,000rpms…very good range. Also, 10-12 pounds is out of the 60 trims efficency range. I would stay in between a 50-57 trim and the 50 trim would be my choice.
shitty deals…i already have the turbo…well whan i was looking at the compressor map 10-12 pounds would be just in that sweet spot…i guess the only way to find out is to try it out…stock redline is 6800rpm…but the b20 can easily rev to 8000rpm…
You have lost your mind if you think the b20 can easily rev to 8,000. I would recommend you stay away from turbo for awhile if you still think things like that. Then again, maybe you were just misinformed…either way back to the drawing board. I would sell the turbo. If you keep it picture this:
…driving noise* “oh yea! Here it comes!” psss-REDLINE
well i guess i will have to slap it on. I was not missed informed a local tuner that tunes stock b20 about 3 times a month have 8 grand rev limit and running over 300whp no problems…but we will see once i do mine…
man its a lags like crazy a friend and i put one on a built b20b with 8.0 comp 5000 full boost redlines at 7500 rpm at 8 lbs. i own a b20v b16 head with a tdo5 on it at 8 lbs. pulls hard and fast 2800 rpm full boost oh and i don’t recomend reving b20’s to 8000 rpm the walls are thin and will break under stress remember a b20b is still a bored out Ls.
You will be fine, the turbo will work nicely. 8k outa a stock b20? you my friend, are an ass. The stock valvesprings float over 7.5k, 300whp and 8k you WILL break the stock rodbolts. If the b20 has rodbolts, valvesprings, and retainers, rev that bitch to 8.5k all day long.
