hey everyone, im reading a lot about the JDM SR20 with this neo vvl stuff and a 6 speed CVT. from my understanding the vvl is like nissans VTEC. didnt know if this was a worth while swap into a P11 or if it was a waste of time.
the VE's are not hard to get, they are just expensive. well atleast in florida and california the VE's can be found in a local Japanese engine shop. but i dont think any one has installed the cvt tranny.
Do a search on sr20ve. they are not to get a hold of. ive seen some for 1200-1300 but you will have to come up with shipping...if your 5spd right now youre in good hands..if will bolt up with your tranny also you will need a wolf ECU...search bud CVT wont work or if you have the $ then it will work, but mine as well buy a Beemer or a benz
You can run the 20VE with the ecu you have no problems. You'll need something to trigger the cam switching though. GReddy MSS or Summit rpm switches are the products of choice as far as I know, although other solutions might available. I run a MSS myself.
To answer your question, if I have understood correctly, a lot of VE's came from the factory with CVT trannies, so that in itself should not be a big problem. The main hassle would probably be that the "ecu" or control unit for the CVT is embedded in the main ECU, so that means you need a JDM VE+CVT ecu, harness etc etc etc misc parts to make it work. Should be do-able though, but I have no idea why ou would want it. Maybe for a daily driver, but when you start tuning, the CVT's a mostly a no-no.
I heard even the stock SR20VET's that came with CVT's are having problems, because the trannies dont hold up to the stock 280ish hp too well.
been done once before here by my mate, so we're just trying to source the parts or a full donor vehicle as I speak. A decent donor car should come in around $800-$900USD so it's a much better option really.
IIRC the only problem is relocating/remaking an engine mount but it's nothing too hard
i have driven some cvt's in primera's and as far as i know most are ok, but they do tend to have issues....as far as modding, i woudlnt recommend it either, the tranny is set specificaly to the motor it has and it really doesnt adapt to anything else
