k...this happened a few weeks ago, but never got the time to put it up here as i was busy putting together my new block.

Stock d15b7 w/ 140k miles. 11psi with an ihi rhb5.











rod #1 and #4 broke to bits. couple of holes here and there on the block.
so ppl looking to boost the b7...pls keep it low!

 

ouch. should have known better

 

Yup, looks about right. Those d15 rods are pretty small, even for a D. Any idea on the HP/tq level? At least the paper head gasket held.

 

hehe... its all good... gave me a reason to get myself a d16 block

 

at 9psi it put out 192hp and 165ft/lb to the wheels. dunno how it did at 11psi. im guessing around 20Xwhp

 

Man like Whoa

 

Ahh yes.. I remember the days of boosting on my b7 block, actually is the was the hours of boost, 1 hour to be exact.. I ripped the wristpin out of piston #3 and made 2 holes in the block..

But the damage was done to the block a few months before that when I screwed something up with nitrous..

 

Lol, this happen to a friend yesterday. He decided he didnt want the motor any more. Having the same Motor and Turbo as you. He decided to remove the WG and have a joy ride for a few weeks.. Little as he know, it last 1 week. Then BANG!! Same thing happen, just like yours. lOLz.... I got some pics, if u wanted to see...

Yes, he was boosting over 14+ psi.. lolz..

 

oops

Good thing you can pick those things up real cheap!

 

what were u using for fuel management?

yeah i figured; you had to have been doing something right if you blew a rod before a ringland

 

just noticed ur sig...wht rods r u gonna use those vitara pistons with??

 

early d16a1 rods

 

Hey, can you send me that uber bin you were running? I'd like to take a look at it.

 

check ur email.

 

im surprised your head gasket didnt blow before that happened...my motor blew a head gasket then a ring but never a rod...it was also a d15b7 running 12 psi on a t25 for a year or 15000 miles.

 

Holly ****...can we say..owned....? **** dude....ouch...

 

Man that has to hurt, but a good chance to put in a stronger motor, with less headaches, hopefully and more confident boost levels.

it was running on a good tune...no signs of detonatoion...
it wouldve lasted me for quite sometime if i hadnt messed around with the speed limiter crap. well, i took it off, and wanted to see how fast she can go...turns out she can only take a few runs of 135+mph

haha ic...

 

How fast were you going when it let go? RPM, speed... Your fuel map looks bit lean.

 

the boost side might look a lil lean...but it was tuned with a wideband and the afr was always around 12:1.

whn it blew up, i was probably close to 100mph, not sure about the rpm, i'd say not more than 4k-5k.
