Good work, Sinner, stand on the long pedal on the right everywhere you go. That way, the engine gets broken in poper, and you aren't smashed by any grandma's going half the speed limit when trying to pull into traffic.

I'm trying to remeber how many times I didnt red line last night... if you know what i mean. But thats normal driving for me though. I'm just extra slow without a turbo now.

d15b vtec rods are the same.

Re: vtec 1.5 blow up/tear down/rebuild/install/break-in weekend.

I have about 250-300 miles on the motor and here are the numbers

compression numbers.

#1 = 170
#2 = 170
#3 = 171
#4 = 175

Re: vtec 1.5 blow up/tear down/rebuild/install/break-in weekend.

That thing must rip pretty hard 8)

Good stuff Nick.

Re: vtec 1.5 blow up/tear down/rebuild/install/break-in weekend.

D15b vtec crack will take 1.6 rods, with vitra piston I think it give you a 9.1 CR.

Re: vtec 1.5 blow up/tear down/rebuild/install/break-in weekend.

so did you electric impact your head bolts on or what?

Sounds about right, because 170 psi is considered normal compression for a 9:1 engine. Cam and such has an effect on this, but it's a good ballpark figure. Boost that bitch, Nick-o!

PS, I just had a very positive experience with a Snap-On portable/cordless electric impact gun... the thing is pretty damn stout, it doesn't hammer quite like I'm used to a pneumatic gun doing so I underestimated it until I used it a bit. Good stuff.

Re: vtec 1.5 blow up/tear down/rebuild/install/break-in weekend.

yeah it has to be close, my accord had 175psi and it was 9.3:1, the cylinders were pretty fresh in it

I used my electric impact on my crank bolt, flywheel, and clutch bolts. I torqued the head bolts down the spec. I usually try to stay in tq. spec with everything side the motor. I cut some corners, but I was doing anything that dumb.

I need to boost the car, but Its finals week. I just finished one class today, but I still one more. It doesnt seem that I'll be teaching next quarter so I'll have more time for my car projects. The GT28rs turbo has a water inlet, I might sure if I'm going to use it. I could T off the bleader valve, but I dont know of a good drain place.

I still have a small mysterious slow oil leak, but I'm not sure where its comming from. Its very slow, but I still want to find it. I think my next project is going to be a v8 so I can test my fuel management unit on it. It alot of people with the big v8s are purchasing my boost controller so I want to make sure my ems can be marketed to them.
