AK-Z Posted March 24, 2006 Share Posted March 24, 2006 I was looking through ebay when I saw a sr20de (neo vvt) from a infiinity G20 (FWD). Now if you had the head and all the electronics from that with a short block from a SR20det from a silvia , would that work? Just curious because I just might be considering that build. edit: I know the ecu has to be remapped for the turbo, but it has variable valve timing, so I don't think the silvia ecu would work.

240Z-DET Posted March 24, 2006 Share Posted March 24, 2006 I do believe that the RWD and the FWD differ because the RWD unit has an extra coolant port facing the transmission. The head gaskets I looked at verified that. That's one of the things that prevents swapping the S13 head onto a B13,14 engine and vice versa.

AK-Z Posted March 24, 2006 Author Share Posted March 24, 2006 Well one of my dreams shot down again. Good info though. thanx Quote Link to comment Share on other sites More sharing options...
Lunar240z Posted March 24, 2006 Share Posted March 24, 2006 it is possible.... there's something about tapping the block or head for an oil line...i don't remember. this is the swap that i'm starting actually. except i'm using the 16ve head. read up http://www.eagle-r.jp/sr20ve.html http://www.sr20forum.com/showthread.php?t=86729&highlight=bigtom Quote Link to comment Share on other sites More sharing options...
AK-Z Posted March 24, 2006 Author Share Posted March 24, 2006 sweet so there is still hope for me. what are the added benifits? Quote Link to comment Share on other sites More sharing options...
Lunar240z Posted March 24, 2006 Share Posted March 24, 2006 VVL... it's nissans version of vtec...read up on the stickies over there. all else equal, a vet should outperform a det Quote Link to comment Share on other sites More sharing options...
AK-Z Posted March 24, 2006 Author Share Posted March 24, 2006 I know what vvl is. I guess benifits are self explanitory Quote Link to comment Share on other sites More sharing options...
AK-Z Posted March 24, 2006 Author Share Posted March 24, 2006 I understand from now from reading the SR20 forum. Couple of questions. Are the crank stroke the same from the DET and VVL? Because one is turbo and the other is NA. Do they make different cams for VVL heads? Will the VVL internals work with a DET crank and has this been done and is turbo charged?

Lunar240z Posted March 24, 2006 Share Posted March 24, 2006 you should just use the det internals. the vvl pistons are really high compression. the only difference in cranks, from what i've heard... is between the 1.6 and the 2.0. so what you need is a vvl head, and a det shortblock.

ProjectSR20 Posted March 24, 2006 Share Posted March 24, 2006 I'm not sure how much truth there is to this. But I remember back when I had my civic, on the honda tech forums there were a number of people that said to stay away from the vtec heads if you are going to go turbo. From what I remeber everyone was saying that it make tuning it a real PITA. Does anyone know if this holds true for Nissan motors? Quote Link to comment Share on other sites More sharing options...
Lunar240z Posted March 24, 2006 Share Posted March 24, 2006 well, nissan themselves put a VET into a car... http://www.nissan-global.com/GCC/Japan/NEWS/20001019_0e.html maybe it'll make tuning hard, i don't know...but it's possible btw. you'll need a VET exhaust manifold. http://www.sr20forum.com/showthread.php?t=120965 the s14 s15 greddy style intakes will work on the vvl engines I bought my engine before i found out a lot of this stuff. i'm just extremely optimisitic. from research, it all seems to work out though.

From what I remeber everyone was saying that it make tuning it a real PITA. Does anyone know if this holds true for Nissan motors? I'm sure its because of there being ecentually 2 maps to deal with because of different timing. the older vtec was like a on and off system for the higher rpm cam, it was "variable" in that when it came on was decided by the ecu. I'm sure the guys on the honda forums didn't rebuild the engine to lower compression ratio either. I think I'll megasquirt it and have a it event timed to change when to switch cams. I remember someone on here a couple of weeks ago saying they were in developement in a Niss data or something like that. a nissan equivilant to the Hondata. Any chance to have VVL control? EDIT: Ok n/m. the whole VVL process is entirely mechanical and has no ecu control at all from what I read, which is a good thing. So I guess I can use any ecu as long as I can flash maps. Sigh, yet another forum I need to join. Thanks Lunar240z for pointing me to the sr20 forums. Quote Link to comment Share on other sites More sharing options...
Lunar240z Posted March 24, 2006 Share Posted March 24, 2006 theres a device called the mss by greddy that people use to control the switchover Quote Link to comment Share on other sites More sharing options...
ProjectSR20 Posted March 25, 2006 Share Posted March 25, 2006 theres a device called the mss by greddy that people use to control the switchover Yeah, Ive heard of that one before. I forgot all about it. I remember reading somewhere that alot of people found it really helpful for tuning. Quote Link to comment Share on other sites More sharing options...
