i've seen alot of ppl who say u can run up to 15 psi on stock internals in d16y8.. and some say anything over 10 is bad. keep in my mind i would be driving daily on this much boost, im jus wondering how i should get tuned on to get good power but stay reliable? im running a turbonetics t3 t4 hybrid with dsm 450 injectors and walbro fuel pump.

anyone who has a turbo d, i would love to hear ur advice but il take anyone who has knowledge on the topics advice.

 

ive asked this question before too lol. ive heard to be safe and conservative 8 or 9 lbs is good enough. but someone said that you could do 12 with a good tune. idk about 15. are you plannin on upgrading the internals or staying with stock?

 

Doesn't really matter the "Boost" so to say. I have a Turbod D, From what my tuner has told me the safe point on a D16z6 is around 215WHP. I would guess it's the same on a y8.

 

its about 200-220WHP. Anything over that and your pushing the shitty stock rods. You also NEED ARP head studs, otherwise your going to get lift and blow the HG.

 

i kno about the head gasket but i fgiured il jus replace it when it happens on down the road, hopefully it wont happen cuz its a been in the *** to replace. so how mcuh whp could i realsitically make possibly on stock internals, a good, tune and a 50 trim t3 t4? i dont want too much psi..

 

no its going to happen basically as soon as you boost.
You can realistically make 200-220WHP before you risk blowing it.
For the price of your Turbonetics turbo you could have built the motor.

 

just get ARP head studs and a thicker head gasket and your good for 200+ DD, better to spend the 180 now instead of possibly cause a bigger problem

 

thats what im trying to tell him

 

youd be suprised = )

true thats a good pooint. any suggestions on HG? cosmetic or oem?? and wat size if cosmetic?

 

u can just get a fel pro one. Thats the one i run and its fine on my built and boosted D

 

i got a cometic head gasket and its holding up fine, just get your stock bore size think its 75mm stock on a your motor pretty sure your alright if u get a slightly larger 1 also such as 76 but i wouldnt go any bigger

 

Very good point, I forgot to mention that. There Fairly cheap... Alot better than replacing your HG every month.

 

OEM is the way i would go.

 

well ive heard of ppl getting different gaskets to raise or low compression.. do ineed to do this and if i get oem, where would u recomend getting it from for a good price?

 

I would just get a OEM gasket from Honda.. But if you really wanna raise or lower the Compression a bit.. Try this. http://www.c-speedracing.com/howto/c...c/compcalc.php

 

how much from honda and which would you guys recomend? i dont want to raise the compression that would defeat the purpose of boosting

 

Not sure, Around 150-200 maybe? Haven't had to buy a new one in a while.. And the stock y8 1 for yourself.

 

Just boost the heck out of it and blow it up. Y8s have a poor oilling system.

 

yea cuz doesnt everyone jus love to throw money away for no reason?

 

Doesn't matter how many PSI you run, it's relative to how big your turbo is. From that, I think you need to do more research before trying to turbo your motor

 

whoa, what? want to try editing for accuracy?

-steel not aluminum
-bolts not studs
-if it's not stretching it's not torqued

i agree with your point though, ARP studs are better than stock bolts in any case. critically important for FI and high-abuse motors.

 

I've never boosted but wouldn't the safe thing be to boost at 7psi and whatever HP your at just keep it there? 7psi would get you a few horses, but not what you want i bet, you want 200+

 

ok. I have a built and boosted D.
You need ARP Head Studs. Don't waste your money on a cometic gasket or a OEM one from honda. You can get a Fel-pro gasket which is JUST AS GOOD for $42. Do NOT get an ebay gasket. I am a ebay advocate, but the gaskets from ebay ARE garbage. I know this from experience. Fel-pro gaskets are good.
The reason you do not need a cometic head gasket is that your compression is already low enough for the stock rods. You can make 200-220WHP on a stock block, lowering the compression is not going to let you safely make any more power. Because its the rods that give out. Don't worry about PSI, its all about how much HP your making.

 

ok. thanks alot bro.. i really apreciate it

 

how about after you get beefy rods? ive have seen everywhere that our d-series rods and weak for boost but what kind of difference are we talking after bigger/better rods? is there something that would be good to beef up in addition rods and can the stock pistons handle a 15-20lbs and what about valve springs? i have a d15z1 and have been thinking about boost for a while know what are the weak spots in the d-series that need to be addressed to make 225-275whp?
