will my stock motor handle 5 pounds of boost?

[lsvtec20]

ive got a 95coupe ej1 with d15b7 all stock and i was thinking about boosting it will it handle about 5 pounds has anyone ever tried on a stock motor? thanks

[xdavidscenex]

yeah dude i heard a gt42r or s372 is a good size turbo for it.

[Vteckidd]

D15 has really shitty main bearings, horrible stroke, weak crank, etc

Im sure it prob has 150K on it too

So no, save your money.

That is a very vague question. 5 psi from a T25, yeah probably so as long as the engine is not wore out. 5 psi from a T4, better be ready for a new engine. Be more specific. About the car and the setup.

What he said. Go D16 if you ask me. What kit is it you are installing??

[EmminoDaGreat]

ROCK OUT !! it will be fine!!

[all-mota]

go for it but at 5 lbs it's only going to add around 20hp or so with a good tune

[DarKStaR]

I forgot what section we were in for a second.....

Lolz! 5 lbs will be fine with a little turbo. Should add a little torque and make it more fun to drive. Just make sure it is a healthy engine to start with. Good luck!

I boosted my stock d15b2 with 140k+ miles on it nearly 10 years ago LOL. I ran 7-8psi on it with a crappy street tune. I drove it like this for probably 15k miles. I finally yanked the motor out because it was getting so much blowby and smoking.. oil control rings had seized into the pistons. So i say go for it.. but don't expect it to last long.

hey people this is the same guy that posted this tread so will it work without blowing it or will it not

[Kourt]

hey people this is the same guy that posted this tread so will it work without blowing it or will it not

yeah of course! Just get some good PVC pipe and hook that shit up..
And who needs a tune??



NO ONE can tell you for sure if your motor is gonna blow up.
Is it a good motor with sorta low miles, will you do it right and get a tune? If so then it should last.
But the other option... Are you going ebay as cheap as you can on a 300k mile motor and not tuning it? Probably won't last..

[Evil Goat]

get a fmu and missing link....slap a s372 on and you're in business....

[JJSPEC Racing]

Actually a S372 will spool so late in the rpm range that it may not hurt it, lol.

[JF868849]

about how much would you charge me jjspec to build the motor not outragous but decent

[JJSPEC Racing]

You want a price on 1.5 or 1.6? 1.6 would probably be the best choice imo.

[bigdare23]

You dont want to build the 1.5L, the rod section sucks (last time I checked it was one off the shelf rod



And why is this in allmotor?!? Turbo that way ----->

[JF868849]

prob 1.5 i have that coupe with 117 miles on it.

[qwick]

Quit telling us what body style you have, ok. All the info that needs to be posted is: what motor, how many miles on the motor, what turbo setup your looking into(if you even know, which i dont think you do) what kinda gains your looking for(not that it matters, it isnt gonna be much) and how much your willing to spend on the entire project.

If more info is needed you will be asked, until then stop posting.

[JF868849]

d15 b7 117xxxmiles t3/t4 gains to out run QWICK how evermuch money it takes please leave negative comments or smart remarks to yourself thanks guys! o yeah if i knew i wouldnt be askin but thanks

[PRO®]

how evermuch money it takes

somehow, i don't see that being tooo realistic.
-less than $1000?
-less than $1500?
-less than $2000?
etc.

o yeah if i knew i wouldnt be askin but thanks

you didn't know, so you were told.

[ejohnson88]

Now if it was a JDM D15b .... That would be another story... Hell I say throw 6-8lbs at it.. that's what i did. the motors are cheap to replace anyways.

[Master Shake]

i'd upgrade motors before boosting it. get a d16z6 with the zc vtec cam. maybe springs and retainers to help the top end out. maybe some new vitara rods or something. then boost. just the route i would go, personally.

Some times it pays to be an asshole . Now that we got all the info needed thing will run much smoother And people will be able to help you more easily.

Wanna make enought power to out run me? Well that shouldnt be to hard. 97 gst eclipse, basic boltons, stock t25 turbo . Just give me a call when your ready.

[tmracing83]

I'd say just keep it na and install boltons and chip it with a good tune and I'll prolly get close to the same power, since your only going to be a 5 psi. Then you don't ha e to worry as much about blowing up your motor.


X2 to this thread being I'm wrong section...



Don't get me wrong. Boost is the bees neeZ. But if your not going to build the motor none? And only on 5lbs... U should just built it up NA
