I picked up a totally naked B20B block and I am collecting parts for a CRVTEC.

I have a set of MID sleeves for it and as soon as my GSR girdle shows up the block is heading to the machine shop.

The problem I have is that my block is totally nude.

If I pick up a blown up LS short block can I transfer everything on the outside of the block over to it. I know the crank and rods are the same.

The question is, timing covers, water pump pipe, sensors etc.

Is the GSR oil cooler worth getting and if so, does it require any other parts like a GSR water pipe?

Are there any other ITR/GSR parts I should be getting for this block?

I already have the P72 oil pan and pickup coming.

I'd like to get some ARP main and head studs for this thing.

 

Also, I've only seen this next topic touched once on H-T.

Does anyone have any info on a non-external oil line for the Vtec head?

I'd like to drill my block to have a GSR/ITR/B16 oil hole to feed the Vtec head instead of all the sloppy external stuff.

 

Looks like to run the oil cooler I need the water pump pipe and thermostat housing.

 

screw the water pipe. it's worthless. next good call on the gsr pan and pick up. I'd go with external set up, less drilling and you can check for visable leaks, just do it clean. if you need rods I have some, pm me. you'll also need a windage tray and oh yah, pull those pluges out the back of the block and put fittings back there to ventilate cranck case properly. do a search on me and I've posted the part # from honda that you need. Good luck

 

The internal drilled vtec line would be just like the factory B Vtec engines, nowhere to leak. I wish I had a broken GSR block to measure.

 

get the golden eagle vtec conversion kit.. things neat and doesnt leak

 

Please stay on topic. I do not want to run an external line.

 

well then your SOL, get a vtec block

 

It's been done before, just because you don't know about it doesn't make your word gospel.

Apparently Asian shops (Korea was what I heard) do it this way.

Without seeing the two blocks side by side, it seems to me I'd just drop a hole into an oil galley. The position of the hole would dictated by the head gasket hole on the Vtec block. I doubt the LS and GSR blocks are cast very differently.

 

Here is a tread from a UK H-T member who owns an internal Vtec oil line B20. He gets flamed by the uninformed too. He even lists the Cometic part number for the gasket.
