i have just recently aquired a rev hard stage two kit with a 7-9 psi wastegate. I drive my car fairly hard and was wondering if stock internals will handle the abuse or if i should just wait to install the kit until i can buy je pistons/eagle rods.This is my daily driver and reliability is key. i would appreciate any and all advise in regaurds to this manner.

Your stock internals can handle way more than that. You want to zero in on the tuning...you should have proper fuel and spark, to accomodate the additional air you are forcing in.

How much power do you want to make?

MachAF

I wouldn't run more than 9psi on pump gas.

Many people run 7psi.

Your engine is not going to be reliable on anything more then 7 if your using stock internals.

MatT3T4

The stock internals can support FAR more power than what is created by 7psi...

And that is a fact!

blkrice

my goal is like 250 whp

Pelican

yeah, we run 5psi on 93 all day, but 9psi on pump seems to detonate. This is an untuned FMU setup. Drag Kit.

If a proper AF ratio is present, stock internals will handle a lot more. Isn't it up to like 300hp?

MatT3T4

more than 300hp actually...me, personally...I'd call it quits at 350whp, but some people even surpass that.

with your setup tuned, you should be able to run way more than 5psi without detonation...

boostin GSR

Greddy turbo kit!

MachAF

Key word is realibility.

so your going to boost 14psi ?? on a stock engine and do it for 50,000 miles?

I'm not saying stock crank and rods can't make 350hp. I know a stock b18c1 crank can handle 450hp and it lived quite comfortably.

If your going to boost more than 9psi, get some lower compression pistons, new rods, block guard/ re sleeved if u got the cash.

MatT3T4

The pistons and sleeves can hold it too. There is no need to build it and lower CR.

One thing though...when we say that the motor can handle this kind of power, you have to remember...it's not under these pressures every time you get in the car. 9-10psi is good for a daily driven street set. Enough power to overpower people when needed, total reliability (if it's tuned). But, should you have to run up to 14-15psi for a stoplight race...and you have enough fuel and spark to do so...seriously, don't worry about it. A well tuned, well taken care of B-series can handle it. It's not as big of a deal as people make it out to be.

MatT3T4

PS: I'd start to think of building if I wanted my DAILY boost setting to be a minimum of 14.5psi or so. Even at that, I wouldn't go below 10.0:1

what do people always mean by wanting the car reliable? i dont really get it. like do u want it to start up every morning and get u from point A to B?? cause if this is all you want u can have a reliable 400whp turbo honda no problem if u do it right.

but if ur scared to pop the hood to re-torque a downpipe bolt or check your own oil then you really shouldnt be driving a turbo car.

I don't mind working on my car, yes I would like to it be reliable, but that's what tuning is all about. Hell if something breaks, I'll spend the money pop open the damn hood and work away until its all done, even if I missing half of my fingers from racking it so hard against the engine and I am bleeding to death, I enjoy every last minute of it. You just gotta realize what your getting yourself into. Be prepared! Most of all have fun while your doing it!

i guess when people are saying reliable, they mean they dont want to blow the motor.

and in that case, how much boost a stock GSR motor can take is dictated by a few main things. 1)fuel/spark and the tuner taking control of it 2)octane level and most importantly 3)the drivers right foot.

100% true

I had a bone stock gsr motor tuned on a dfi system running 17 pounds if I can remember right on a small t3/t4 with no vtec and made 330whp.

JDM88EF9

That sounds good... Can you give me more specs on what u did?

Elite Hatch

A guy that purchased our turbo kit...he was running 15lbs on a stock b16a tuned with hondata and got 351hp to the wheels....

here is a post about it

Thanks so much. Coo link

How do you figure a high c/r stock piston motor can handle more then lets say 10 lbs? Are you some kind of tuning wiz and can defy the laws of physics? Please inform me how "your stock internals can handle way more then that". Obviously you dont see on a daily basis what high boost and stock internals do to each other. I love this kids advice. Stay at 7 to 9 psi and youll be fine. If you want more opt for a set of forged pistons and at least a set of shot peened rods before attempting to go ballistic. Then again you wont have a b18c anymore will ya?

let me guess. low compression pistons, intank fuel pump, vortech 12:1 fmu, stock injectors. your ideal set up?

Elite Hatch

You can boost over 10lbs on stock motor the guy I talked about above does it and hasnt had a problem at all. Its all about timing! If you have a hondata or stand alone its not a problem. I am an advocate for lowering compression but I do know that stock compression as long as timing is figured out is ok. I personally have a stock motor with an Inline Head gasket that works best for me!

MatT3T4

How do I figure...? Because I have done it several times, on several cars, for several years. It's not as taboo as everyone thinks.

Boost is relative, subvert the dominant paradigm.

IMALLSLO

My ideal setup? hmmmmm twin weldon pumps attached to two pre paper and two magnesium element post filters. 8 1500 cc injectors to twin fuel rails pumping methanol through a h/c 1.8 liter motor boosting 35 + psi on a turbonetics t66. Any other questions?

W.Zero

with the right head gasket, fuel and good tunning a stock gsr can hold 20lbs. it is possible just ask inline pro about there head gasket. anyway if you want a reliable turbo car i would leave it stock internals with all the bolt ons possible (fuel,ignition,etc.), a good fuel management, a good tuner, and inline pro head gasket. dont go more then 12lbs and call it a day.

i fully built my motor and to tell you the truth its NOT reliable. i wouldnt fully built a motor unless you plan not to drive daily. i drove my car daily and didnt get no more then 9k miles.
