its a T25 turbo type-rs bov bootleg piping lol intercooler size 28-6-2.5 what do you guys think plz help i dont know about turbos thats why im asking

yaaj1320

i ran 15lbs with the 14b,dsm450cc inj., and chrome

lunaticracer21

but im stock and dont have alot of money so i need the motor 2 last

stockb18c

10 psi should be fine i ran 13psi on mine and lasted two years...its a small turbo remember that

THEDirtyDseriesWOOT

i ran 15 on my y7 for a while till it overboosted to 20+ and boom .. its not how many psi its how much hp.. 220whp at the max on stock rods get it tuned on the dyno please for the love of god u cheap bastards

AMLS4dr200whp

its all in the tuning but I wouldnt go past 12psi

boosted_d16y7

I ran that setup on all stock internals and a 12:1 Fmu at 10psi. After 10psi the fuel cut out. Just keep an eye on your oil and turbo seals or you will spin a bearing like I did.

Thanks guyz I don't know what I would do if there's no honda tech lol

The 3 main problems d-series face are overloading the stock rods, too much timing (breaks ringlands), and over-reving (oil pump). The y7 also has a less-than-stellar crank, as the oil passages only go to one side of the main/rod surfaces. Not being cross-drilled is the main reason I think y7/y8 blocks spin bearings.

As long as you don't run crazy timing (1deg/psi is conservative) and don't rev past 7.5k, it should last a long time. Some guys run up to 250whp with stock D's, but they are usually in good condition and they maintain them very well.

all true except for the crank part.. just beacuase it has one passage isnt the reason it spins its the oil pump. i had a z6 crank because of the 2 oiling holes per journal in a Y8 block and it spun a bearing i found out that the stock z6 oil pump flows 30% more volume than the y7/y8 pumps

lunaticracer21

so i need a z6 oil pump on my y7???

lunaticracer21

N/E ONE???
