S14 SR20DET with VVT in an 89' S13, am I wrong for doing this?

Just wondering if anyone had anything bad or good to say about the S14 version of the SR motor and its VVT feature, since Im about to pay a bunch to put one in my 89' 240sx next week?

Good decision.

VVT is Nissan's Variable Valve Timing, pretty much the same as Honda's VTEC (which is I believe stands for something like Variable Valve Timing and Engine Control?).

Of course its a good engine, if not everyone and their brother wouldn't have a 240 with an SR. Have fun, good luck with the swap.

Ive heard from everyone that the SR's are good motors but Im just hoping the vvt inst just one more thing to go wrong with. Does anyone know if the difference between one with VVT and one without is worth mentioning?

the only problem is your cam selection is very limited if you ever decide to get aftermarket cams

i think like 1 company makes 1 set, other than that it disables the vvt

it's good if you don't plan on aiming for crazy hp numbers. for a mild tune it's good. lots of honda guys dump their vtec also later on for wild camshafts which basically is "ahh it always kicks in.

no, you can definately get rwd sr's with vvt. i think itd be sick to have the s15 engine just for the 6 speed.

Seen the clip, its rear wheel drive, and it has VVL so it will be interesting to see the dyno on this one.Read somewhere that it’s supposed to be about 220hp (dunno if its rwhp or at the crank) but that’s stock. I’ve also seen that the stock injectors for this motor are bigger, and the turbo is bigger and of better quality than the standard red-top SR.

If any of my info is wrong... please correct me

My ultimate goal is to get about 320rwhp out of it with the right exhaust/headers/injectors/boost, and other mods, but still try to keep it reasonably reliable, I’m not going to do much racing, just like to know that its there if I feel I need it. I mean you never know when a supra might step up, and I have a friend with a base C-5 Corvette that needs his eyes opened up about the power of the tuner.

the 220 is at the crank, youll need a few extra things to hit that

you dont get a header with this, its a turbo manifold

youll need a bigger turbo to hit 320, plus all the things to support it

ur all thinking of VTC...

The SR20VE is the VVL NEO motor peeps. FWD, non-turbo, around 187 at the front wheels, on a Primera.

For a mild tune like Juujai said S14 SR is good. If you get a large turbo you're going to want cams which renders your extra money for VTC useless. However for 320 WHP you don't need really need a cam upgrade. Just a bigger turbo, injectors, tuning on top of the usual bolt-ons one gets with the SR swap.

I've heard of the vvt holding the motor back if you want some horsepower eliminate that and deal with turbo and air/fuel delivery.

It has been a while but, if I remember correctly, the 6 speed is just 6 forward gears (and reverse) crammed in to the 5 speed gear box. Due to this confinement they don't hold high horse power well.

people say that but it doesnt matter until your making astronomical hp numbers, at that point your thinking about the durabilty of the 5 speed as well

There is nothing wrong with putting an S14 VVT SR in your 89! The only problem that lies ahead of you along with the heater core hoses and wiring harness is that when you drop an SR into a 89' or 90' 240sx the power steering lines don't line up. You will have to get a rack and pinion steering from a 91'+ and put that in place of your stock one. If you are paying someone to do it hopefully they know that or you are going to hit a snag when you try to install the SR!

most of the time its just not worth the extra money to buy an s14 sr since it makes pretty much the same hp as an s13 sr....... i always thought that a late model 180sx black top sr is the best for the money.... since they have the good head( i believe) and most have the same mileage as an s14 sr
