Question?



Hi Team



I am planning to do a conversion on my '96 Elantra J2 1.6L. I wish to purchase the 2.0L which I understand is a straight swop but I want to add the CVVT and ITB's as well. I'd like to know from the team who has done or seen this conversion or similar before (adding CVVT from the later beta II engine) and what are the benefits/disadvantages that comes with making this change on the beta I?



I have seen some 2.0L J2 engines in Hyundai Accent's with the CVVT attached and making good power. What are the complications behind making this change?



Thanks in advance for your response.

In order to get the CVVT functional you will need everything from the donor car, all wiring harnesses and ecu. The CVVT doesn't add much if any performance gain over a non-cvvt 2.0.



I don't know much about the 1.6 Beta, but I would assume the wiring harness is the same as the 2.0.

So you should be able to drop in a Beta 1 2.0 with no wiring required, just need to use the 2.0 ecu.

You could also get a Beta 2 non-cvvt motor and use Beta 1 sensors and manifolds, ecu.

I don't think it's worth doing a CVVT conversation without a real way of tuning it.

as for independent throttle bodies, that's probably going to be a custom fabrication job - time consuming and/or expensive. For that kind of money, you'd probably make more power with a small basic turbocharger setup.

Could also drop in a 4G63T from a Mitsubishi Eclipse or Evo if you really want to get unique! lol

You will need a standalone ecu for an ITB setup. Perhaps you could use an RPM window switch to control the CVVT. But don't expect the CVVT to add high rpm hp. I believe it only really helps low end power, below 2,500 rpm?

Also to really use ITBs, you will need to have way bigger cams!

Hi guys



Thanks for all your responses. Much needed insight.



I have decided to scrap the CVVT idea, after reading I learned that cvvt only add power at low end. Nothing else. This can be more than achieved with much simply enhancements such as cams etc.



I'll be with the 2.0L beta, cams from the 1.8 and gonna assess the benefits of the ITB setup.

Thanks for adding the bit about needing the 2.0L ecu as well. Didn't know that bit

You are planing to use the OEM ECU from a 2.0L?
