Please help my uneducation.

I've been searching for a while for this information but i'm coming up empty handed.

I'm currently running a JDM SR20DE, and i'm really really really wanting to go VE. Now, I've looked in the past on the differences in the DE High-Ports and Low-Ports, and I know that the High-Ports are far better in a performance standpoint. The Low-Ports have a reduced rev due to changes in the cams and the inverted intake and ECU, etc., all for the sake of emissions. Knowing this I am now a die-hard High-Port man, and I have been for nearly 2 years now. The question that i have is this:

Other than the inverted intake and cams on the VE, is there any difference in the VE head(top end of the head where the cams are that is) from the DE head. I really want to keep my High-Port set up, but I also really want to have all the perks of VVL. I know that the SR's in the front/all-wheel drive set up is completely different than that of the rear-wheel set up. I have been thinking of just getting the VE cams, ECU, distributor, solenoids, etc(basicly everything save the head itself) and putting it in my High-Port head. Has anyone done this with theirs or know of the differences so that I may further advance my knowledge of these engines, so I know what I would need to do. I've been searching the forum and have so far found nothing reguarding what I need to know.

Any help would be much appreciated. And, not like it makes much difference to some of you, but please don't tell me to search. I HAVE. But, by all means, if I have missed something, or did not search well enough, please point me in the right direction.

Thank You,
Lance

Granted, I'm not an authority but hopefull this will help:

As far as I know the reason no one has swapped the VE cam setup into a non-VE head is because of the oil passages and possibly some actual castings in the head are specially designed for the VE. Even in cases where they have a VE in a RWD car (which in the case of the S13, S14, and S15 are high-port engines to begin with) they use the VE head.

It would take thousands if not tens of thousands of dollars to fully explore, prototype, and produce a working VE head conversion. I'm not seeing that worth a couple extra HP. The VE head port and valve design is proven to make 220whp+, who can say they've made that with a streetable high-port N/A non-nitrous motor?

The VE head which is the core component of VVL is what makes a VE engine have VVL.

There are plenty of guys who have fitted the VE head, inlet manifold and dizzy to a RWD DE block and made some really good power. The DE RWD hi port head is nearly 20yrs old in design. The full VE head is a much better idea!!

i'm not doing a rwd app though. i'm doing fwd. and i may even go awd eventually.

i dont think ive ever seen a thread where someone is THAT confused about the two motors.

iamhappy46 · 07-13-2006, 11:40 AM

OK, I was a bit confused...

The point still remains, fit a VE head to the DE block. You will not be able to fit VE head components to a DE hi port head.

WOW, just WOW.

lukamccloud · 07-13-2006, 02:36 PM

well i was hoping to get some help with this. instead all i seem to be getting is some people who feel the need to bash.

I'll be doing this to a B13 SE-R. the b13's came all wheel drive in japan, but only in the four door model with the SR18DE. and i was actually thinking of going more toward the rnn14 conversion throughout. "blah blah blah it can't be done. blah blah blah." sure it's a lot of modification, but it can be done. cut and weld, baby, cut and weld.

I can dig up dozens of threads on the 4wd conversion subject. They're invariably by people new to the platform, who for whatever reason think it's a good idea. Bottom line... none of them did it.

first of all, if you dont know what makes the ve head superior to the de, then youre already lost and need to go read some more

Serban · 07-13-2006, 06:56 PM

You might need to swap over the rocker arms from the ve head to the de head also

lukamccloud · 07-14-2006, 07:09 AM

ok... i did not post this thread to be bashed. i was seriously looking for some help from someone who might actually take the time to post something helpful instead of wasting time putting someone down.

Not to add to the list of 'bashers', but...

Please, read THIS thread BEFORE getting TOO high on your soap box...

This is simply a friendly reminder before you get too carried away.

Dan_93SER · 07-14-2006, 12:06 PM

Okay, let me help by spelling it out for you.

Any supposed advantage the DE high-port head has over the DE low-port head is far, far, FAR outweighed by the advantages of the VE low-port head over either DE head.

Serban · 07-14-2006, 12:14 PM

Furthermore, if you did any searching, you may have found this picture:

It compares the VE intake ports over the DE intake ports. Can you guess which one is which? And even if it was possible to put VE valvetrain in a DE head...would you still want to use a DE intake manifold?

chriscar · 07-14-2006, 12:14 PM

It's WELL known that the VE head flows better than the DE head. Where are you getting your information?

And as far as bashing, stop whining. You come here with these half assed plans to convert a B13 to AWD, and somehow magically transform a DE head into a VE head, both of which are for all practical purposes impossible tasks.

Prove me wrong, and I'll pay for your forum membership for two years.

nismo94tuner · 07-14-2006, 01:07 PM

You should just find a VE head for about 800-900$, slap it on your JDM bottom end, then call it a day. The AWD idea is pretty much something that will not be done any time soon, if ever. VE heads > DE heads.
