hey guys i was reading about the ve's and it sounded like teh only difference between the 2 moters is the head so is it possible even remotley eith correct ecu, etc. to swap heads liek the honda guys do to keep costs down and to prevent the hassle of pulling the moter?

What is this DE/VVL

Sorry, no ls/vtec copies for you, do a search, look it up.

It is possible. A member from Taiwan once posted about it. Basically, the idea I got was that you could use the VE head on a DE block and therefore have the VVL motor. In Taiwan, they have a law that doesn't allow for motor swaps (some odd law he was mentioning), so doing what he did was the only way to have a VE in his car.

It is better for you to do a full motor swap anyway and learn something from it, IMO.

I highly doubt a DE/VVL copy would be as reliable as an original SR20VE.

I know that when you do LS/VTEC things get kinda screwy, rod/stroke ratios get messed up , and basically it doesn' last as long, well most dont.

being that both the VE and the DE are like the same block, rod/stroke ratios wouldnt get messed with, but i dunno, i just dont think it will be as reliable.

IIRC its possible if you use one of the newer roller blocks. I think the newer blocks are slightly different then the older ones.

Pretty much. Your 91 engine is actually a highport though.

plus your 91 highport has miles on it. youd want to rebuild the bottom end if you did a head swap. if you were going to do that then why not do the motor swap. no sense in takeing the head off if you arent going to fix everything else down there while you got it apart. anyway id swap a motor before i swapped a head on one of these any day. especially with the VE prices coming down...

nxnoobie your 91 NX has a high port motor. not a low port. just for your info. lowport sr20 motors began in the US in 1994

The myth about the LS/VTEC motor not lasting is overrated. A motor is just as good as it is built. If you skimp on it. It will skimp on you. Build it right and you should have no problems. I've seen plenty of LS/VTEC motors last well over 100K. I don't know about this DE/VVL. But then again I'm a noob.

Just curious. How are the cams shifted? Same way in the honda? Oil pressure? What about the mapping of the fuel? I know I should search. But I am a lazy ass. :tongue:

I dunno where i found how it works,(if i find it i'll post up).
But i do know it is a 3 stage, while vtec is a single stage.
..what that means?, i have no clue:), i forgot.lol

It means that with VTEC botht he cams switch over at the same time, as they only have 1 solenoid to do it. With the VVL, there are 2 solenoids, one for ach cam, hence the 3 stage part of it. 1 stage is both cams on low, then 1 cam one low, one on high (stage 2), and then finally both cams on high (stage 3). They do switch over with oil pressure, there is a thread in the this section that says how VVL works, read it it is very interesting. the nice thing about our cars is that they are stong as hell stock, so its easier to get a complete VE and swap it in than just the head, becasue it is hard to find just a VVL head. Plus you wont have to worry about "skimping" on the bottom end, just leave it stock, and it should last for a very very very long time.

What about putting DE pistons and crank into an SR16VE? Will the SR20DE tranny bolt up? I would think it would since they are both SR engines. Might be cheaper if you're willing to do the work yourself. I'm thinking about this for when I get an NX instead of going the turbo route.

You havent searched, eh? This has been covered sooooooooooo many times. You can do what you are talking about, it is possible, it is cheaper if you do you own work. Itt can also take a very long time. VE's are getting cheaper now. I would just buy a sr20ve, unless you get a kick ass dela on the sr16, and you have a really good hook up on the parts. Search, and most of your questions will be answered.

yeap everybody jumps on the bandwagon of LSVTEC
no knowing that this set up is for the true tuners
that could crack the engine apart and put it up to par
and know how to maintain..
specially since the fuel mixture has to be managed correctly
or it will not last..

so my best advise to all honda wanabe techers
is

if you have to ask how to LSVTEC...
dont deal with it....

cause all the $$ involved in it you could have bought a type R
or boosted your LS block...
