My Engine Build 2007

So I had my old B16a engine taken out from the chasis in a friends shop. It was puasa so we didn't spend much time on it so it took roughly 3 weeks or so. The engine has seen well over 150,000 km of abuse, every single day screaming from 5000rpm to 9000rpm without ever giving up. The CTR valvetrain were up to the job and the CTR piston was healthy to support the compression that the camshaft needed.

Finally, the engine gave up and blew the mugen metal headgasket resulting in loss of compression and leaked oil almost everywhere. We're gonna miss you, you old sucker~

I picked up a B20B long block for roughly RM$1.1k and dismantled everything to the bare block. Everything went out to specification from plastigauging the mains and rod bearings, oil pump, seals and every new parts were going into this 2-litre block. I wonder if this CRVtec is worth doing... well, we'll soon find out. I repainted the whole block after cleaning it with solvents and detergents and then sprayed it with high temperature silver so that it looks nice.

New piston rings are going in and checked the clearance using a feeler gauge that I bought. The piston to wall clearance turned out ok with 0.025mm cylinder 1 and 2 but 3 and 4 seems a little bit loose at 0.040mm but still within the allowed tolerance. I normally use NPR piston ring set but I decided to go cheap and went with RIK which IMO works just fine but break-in for the rings has to go in incremental rather than the normal break in procedure to ensure good seal.

Thats just me sliding in the piston rings with the piston to make sure its properly aligned in the bore.

The Finished block, well minus the oil pan though. And my garage floor..

Here's a few insight of the PR3 head. I prepped and external oil line fitting to the head. Because the flow of oil to activate the VTEC solenoid has been blocked as per the picture, i needed to run an external oil line from the block to the head as such. It'll be boring running without it. Plus, if i didn't block the oil hole of the head, it'll leak like crazy. Nuff said~

Here's the oil line from the back of the B20B block, i had to tapped through the oil pressure sensor.

I didn't need the pressure sensor anyway coz i'm using a full standalone to tune it. And here's from the line towards the back of the head.

Due to unforseen reasons, we were rushing to assemle everything and then put it into the car. So i didn't take much documentation on it and missed a lot of photo's. So here's the finished product of the CRVtec into the car.During initial start up, as expected, it ran pretty rich so I had to put 40% additional to the existing fuel trim to make up for the extra 400cc displacement. Fyi, i used stock 240cc injectors coz my injectors didn't come in time. All in all, i had to increase another 20% fuel trim overall in the fuel map and increase 3 degrees advance to the ignition timing. Putting 2 litre on a EG chasis is a blast to drive... one's gotta experience it to believe.BTW.. I exchanged the whole block with a B18C and building that one up. So I'm running totally stock B16a again. Till next time
