wouldnt this mess with the handling? putting a lighter motor in would through off the NEAR 50/50 weight ratio. Just a question, let me know if im wrong.

 

those motors have such potential...

 

wow....that looks like a clean fit...almost like it was meant to be there

surprised how big that 4 banger is.....good luck with your project...sounds very promising and very unique

 

Since when can a stock SR20 make 600hp out of the box? I don't care what turbo or NOS you use. That motor will not make 600 without being built. I know people that will pay you a lot for that info.

 

if you read in his quote he said the sr20 will handle 600 hp on a stock bottom end....its right there in front of you

 

not sure what the weight ratio will be once teh motor is in but, chris forsberg used it as a D1 drift car....so it shouldn't be so bad. I am hopin got get around 450 to the wheels onces everything is said and done. I will keep you guys updated

 

450 is definitely obtainable. Just the right setup will work.

 

Just a news flash for you. Our cars do not have near 50/50 weight distribution. The SR will help balance that and you can also try to lower the motor a bit for a lower center of gravity

 

when you started the last thread, i really didn't think you were serious, or knew what you were talking about. i really respect that you are going through with this, as i hate how everyone talks a good line on the net, but never does anything. i'm really curious about the driving impressions still, and would love to drift with you some day. a couple of weekends ago i rocked my z to a first place finish at drift showoff in colorado springs, so i know the z is a great platform. i'll probably eventually toss a turbo kit on my z and drift it to death, and during that time it would be pretty neat to see how different the two zs feel. what drift events do you plan on attending in the near future with the car? i'm always all over the country, and would love to see your car out there.

anyways, major props, and have fun! make sure you put a good diff in the car, and tune the car safely enough that you can beat on it all day long without it blowing up. this means you need alot of cooling mods, my last FI drift car went kabloom because i didn't pay enough attention.

 

hahahaha....2K2005, are u for real? The SR20DET has been pushed to over 1000HP completely built in JGTC in Japan!! As far as 600HP, i didn't say it makes 600HP from the factory (if that was the case, every car on the road would be a Silvia). I said, it CAN handle 600HP on a stock bottom end....and if you got people lined up to find out how......ask me in a few weeks when I am done building the fastest S15 Conversion in Illinois!!! here is a sneak peak: https://my350z.com/forum/exterior-and-interior/130397-new-project-pic.html

 

highest power SR I've heard is built by Phoenix Power Japan, 2.2 liter, 920hp at about 11000rpm. drag S14.

SR was used in GT300 class and it was never pushed over 350hp. 1000HP for JGTC? GT500 class makes no more than 600hp.

SR is a good motor but the weakest point is the stock paper headgasket, it is not recommanded to boost more than 1.0kg/cm2 on stock headgasket, slightly detonation will blow the HG. in japan, people change out the HG when the do upgrades such as boost up.

SR is not the strongest inline four, it still has an aluminum block and alum cast piston. 4G63 is iron, 3S-GTE is iron. and they can make as much power as SR can.

There are people out there made over 600whp in stock form, ON THE DYNO though. I haven't seen his car on the track yet. it might be ok for drag, or a short blast, but on the race track, full day of abuse, no way stock motor will hold together.

I sell SR parts and work on SR all day long, I had 2 S14 with SR and one makes 450whp stock motor. it's fun. but I like VQ more.

 

that is some amazing numbers from a 4 cylinder engine.....mind boggling.

obviously, the guy who made this swap did his homework....that would be a lot of work for nothing otherwise

i am really blown away at the potential power of this motor

again, good luck with this project....keep us updated on your progress

 

Yea, I actually had a SR20 powered S14 before I bought the 350Z. There is a pic of my S14/SR in my Sig. I am very much into drifting and would love to see some of yall out at a drift session. There is a drift day in AR on july 16th if anyone is interested! I also prefer the VQ over the SR. I think with a nice single turbo setup would be killer on this car. Much better power curve, and the TQ is to die for! Very useful in drifting! If you want check out some of my drift vids in the drift section of this forum. It was from the last drift day in AR! Hope to see yall out at an event sometime.
Jon

 

The S14 SR also has Variable valve timing.

 

How Dumb. Excuses to put an sr in a car. personaly that motor will max hold 400+ the rod bolts will start to break and or stretch along with the head studs. thats the first thing to go. Built that motor will have to run on race gas. SR motors are Prone to warping at those powerlevels and he will have to do it allll over again. I love SR20 motors just not in a car where you can make VASTS amounts of HP on awsome motor. Built VQ is the next big thing

 

I still don't get why people keep saying this. THIS IS A PURPOSEFUL SWAP. A bolt on SR may not last as long as a built VQ but I'm sure he put it in the car for the same reason Forsberg, Signal and some others companies did- WEIGHT LOSS. Granted our cars are bad ***, but if you haven't noticed they are HEAVY. If you get on a road track or auto-x course this is very noticable and is why this idea has been in my head too before I even put my Z on the track. We can build the VQ drop 10K and boost the **** out of them but at what point is that negated by our cars body weight. IMO for a track car I would much rather have a 2600-2700 lb 300-400whp car than 400-500+ whp 3100-3200 lb car. Sorry for the rant, I just wish people would also look at it from a functional standpoint. We have a great chassis that weighs too much.

 

you must have nice 50/50 balance now and lighter overall. You can probably take some weight off the rear hatch and still get 50/50 balance. This is not bad, god job looks really fun!

 

Anyone ever confirm the actual weight savings between the two engines?

 

IllPhill,
One point you are missing is that the SR20 cant make torque like the VQ35. I think the SR20 is a good motor, just not in a 350z. Its like taking a V12 Ferrari and putting a Ferrari V8 in it. For racing, balance etc, why do JGTC Nissans in both GT500 and GT300 use VQ motors? They can install any Nissan motor in the car if they want but they stay with VQ, if the SR20 really offered better HP potential and better weight balance then they would use it.

 

yeah, but even so, they use the VQ30, not the VQ35 like what we have....
