My VE head swap how to (picture heavy) + Roller Rocker! - Page 8

BaBySkYLiNe · 02-18-2009, 03:21 AM

Man this sh*t soubds Complicating......... I wanna do the same setup with high compression piston... Have tooooooo Many Questions and im not sure i can get them all answered I guess when i buy the Head i'll be back.. Till then RESEARCH is *** it is.. Good Fukin Writeup ***, even if im still a bit confused it doesnt seem as EASY as an LSVtec motor build ive done to my civic (P.O.S.) 12 Sec Honda.. I want an 11 sec ALL motor VVL!, if HONDA can do it all motor i HOPE NISSAN can too, *** im a FULL blooded Nissan Head

Anyone have any dyno numbers with the de/ve hybrid?

How was the clearance on pistons and valves? was the recession on the pistons enough to clear the VE calves when the solenoids are engagged?

bump..I missed reading this part, pardon the first question prior to this post. Anyways if I have a high comp pistons as shown in the picture below, will I be encountering valve piston clearance issue????

I am about to boost this hybrid project using a t3 12- 15 psi. I have 1.50mm cometic metal gasket. Is it best to change piston or should I take the time in measuring if it'll make contact?? tnx

damm man thats cool! i got a rr that over haeted and im looking 4 a vvl head to do the same thing like u but i can't find the vvl head 4 my roller rocker engine.

Has anyone tried driling the hole in a rwd block
to use the stock passage?

Not going to happen with an S14 block as the oil passage sticks half out over the block.

Yeah.. what he ^ said. We did put a motor like this together using the method I described in the beginning. Just make sure you seal up the head passage right.

I am really interested in doing this swap.. What would be the list of necessary parts? for a highport/93 Se-r..

VE head w/ intake manifold & TB
vvl solenoid (comes with head?)
oil line pieces (tap, plug & line)
VE oil pump (& VE crank pulley & spacer)
water pump (do you need this? if so, VE or DE?)
head studs
re-programmed ecu (Calum daughterboard with his VE program)
head gaskets, VE right? (& possibly the VC gasket)
and..?

Anybody have any idea how many horses i would be pushing in a US SR20DE b14 ser with bolt ons?

PJizzle · 05-06-2009, 04:54 PM

^With a SR20VE head

Would it have been easier to use the SR20VE ECU if you had access to it? Where on the harness did you tap into for powering the solenoids?

Luis · 05-19-2009, 12:22 PM

SR20VE ecu is pretty much useless unless you happen to have the CVT harness. You just need to buy an rpm switch that can provide power to the solenoids.

PJizzle · 09-19-2009, 04:18 PM

This thread has answered the majority of my questions, great write up

. I'm a little confused on clearance issues though. Will highport de pistons cause clearance issues with sr16 cams

?? If so, what are my options?? Thanks

cees · 11-24-2009, 06:20 PM

What computer did you use so the vvl kicks in? and at what rpm does it kick in? What kinda power does it make?

cees · 12-01-2009, 12:16 AM

what head studs were used for this build?

burnoutkid · 12-08-2009, 04:00 AM

Greddy MSS works well in activating the solenoids.

High port pistons will hit your valves hard even with a 1.88 gsket, the safer option is to use DET pistons or the VE ones.

So, the solution looks like you need to get the head on the drill press table and secure it. Then select a plug that will fill the hole and drill and tap the appropriate threads in it to plug the hole in the face of the head. Make sure that you have drilled it deep enough that the plug will be .060 or so below the surface of the head. Once you have done that turn the head on its side and drill and tap for a -3 line in that boss directly to the side of the return and make sure that you drill all the way in to the oil passage. (In the picture it looks like this has already been done) Once that is done you have to drill and tap the block near the pan rail toward the "back" of the block. (search for this as it has been discussed numerous times) Then you need a -3 90* for the head and a -3 straight or 45* fitting for the block for the oil return line and you will have this modification made in a way that will work very well. This entire procedure is outlined in a number of threads so search and ye shall find.
