With a million dollar, a lot of you won't touch either one. LOL... With a million dollar, I'll make it a 1,000,000UZ.

 

he's gotta make up for that tiny liter size somehow

I know, i though ya'll caught that

Anytime brother

 

Why would i buy both a sc300 and sc400? I can only drive 1 at a time. Plus i am the one who works on both cars.
maybe, maybe not. I gotta go look and see if i have an oil leak thats burning up before it hits the ground. I dont have the white smoke associated with oil burning. anyways that off-topic, i can talk about that in my thread.
A couple issues with that. First unless your car is low miles which most older sc400s arent, i wouldnt be risking boosting the car. Second your still stuck with the crappy auto tranny. Also are you making 400hp and i personally dont wanna believe you made that much hp with just a tune and a super charger. It just seems unbelievible. Also if so how long have you made that much power? Something tells me that auto tranny wont hold that much power for very long, especially if its a high millage tranny.

Your right that if you buy a 1jz-gte then you are getting an engine/tranny with unknown history but the same applies to buying a car. You can only tell soo much from engine oil/tranny fluid.
WHAT? Since when? If your talking about the 400-500hp range, the 1jz can make just as much power as the 2jz.

So price wise we are talking about 2g to get the sc400 up to like 300 rwhp, while for around 2.5g you can get a 1jz/r154 and double that for new turbo/manifold,injuectors,boost controllers you can make 450hp.

If you only wanna make a little bit of power on top of the engine, then sure supercharge your sc400 but if you wanna get up to mid 400s then 1jz/single turbo is gonna be more bang for your buck.
That engine is completely built. Completely unfair to compare that a jz. Were not talking about engines that have had their internals rebuilt.
Amini9 is right stock the sc400 is the better car. But if you actually want a manual tranmission and around 450rwhp, then the jz is gonna be the cheaper engine to achieve that on. Even if you get a sc300, your better of swapping the engine. Its just easier to do a jz swap on a sc3 over an sc4.

 

What i find hilarious is that you believe the tranny in your SC3 could handle boost any better than one in an SC4, what you dont have mileage on yours, LMAO

 

i never said that. They both have crappy trannies. Its just that with the 1jz, you get a r154 tranny. Thats why the swap is soo good, you get the engine with the good tranny you need to hold the 450hp the engine can make. Ugh right now i am really tempted to get a 1jz/r154 but part of me wants a 2jz-gte just for that extra tq.

 

Dyno result will vary from machine to machine so that's not accurate to know how powerful your car is. Usually, Dynojet gives more lower number than Mustang dyno so if you compare 450 hp on 1JZ (on Mustang dyno), you'll lose to a 350 hp on a Dynojet. Don't be too optimistic about dyno number. Again, I haven't seen 1JZ with stock internals that pass 350 rwhp. Also, it's just not the rwhp, it's about the torque. 350 rwtq might break a r154. If you talk to the tuner who had done several tunings on the 1JZ, he'll tell you that.

You may be right that the SC4 tranny might not hold more than 400 rwhp. That's what I heard about. However, I'd like to see if it's true. When the SC4 has 400 rwhp, it might have around 450 rwtq and can rip the rear tires off easily.

Once you finished swapping to 1JZ, let's go to the California Speedway for 1/4mile run, or maybe Irwindale track for 1/8 mile run. I'd just like to show you how a boosted SC4 is capable of. You can maximize whatever boost your 1JZ can take. I still have the auto tranny of the SC4 and it's been running for a year now for 9 psi. Now I just upped the boost to 13 psi with some tuning. The only mod that I have on the tranny is the Lextreme high stall torque converter and the tranny cooler. I'm just letting you know ahead what I have.

 

This thread is hilarious. You guys' this engine vs that engine threads are alot more cordial than I'm used to on the Nissan boards!

I had in mind to buy an sc3 with plans for the 1jz swap after reading 2.5tSoarer's article in Modified this month. That article claimed he had over 700hp with a stock block. But this thread has made me reconsider buying an SC at all.

Is it really true that it is rare to see a 1JZ with stock internal surpass 350whp? That seems a little underwhelming to me considering the total weight of the car. I thought the 1JZ was more stout than that and was hoping for more average numbers around 450-500hp. Can anybody shed some light on what is typically required to reach these kind of numbers with either the 1jz or 1uz?

 

Read my sig. I've had 2 S14s and a vert. They're much funner than any SC.

 

^^^ Point taken. If I get one, I guess I'll just forego making it fast and just make it look like an orgasm on wheels. I'll still have the s13 to be fast in...

In that case, stock vs stock, I'll take the SC400 over the SC300.

Edit: Either that... or swap in an RB. J/K!

 

OK guys lets come back to reality here!!!

This poor guy is buying a 92 sc XXXX

First you forgot that this is not a brand new car! He will most likely spend all the money to get it back to normal(suspention/bushings/doors/head lights etc..)

Trust me by the time you get your car up to date , whether its 300 or 400 you WILL BE BROKE !!!!!

Although i have to vouch for 300 because they are so easy to fix

 

450-500 bhp is about 350 rwhp or a little bit more, only if you have the manual tranny. Anyone can claim whatever hp that he feels like, such as on that magazine. If you check the link on the previous page of many 1JZ dyno, you'll see how many out there that had passed 350 rwhp.

 

Lol! That's what I looked at that discouraged me! I only saw a handful over 350hp. But maybe I misread the graph. I do know that as soon as I made that last post, I poked around in the performance forum and found some positive news. I can't wait till I leave work to look into it more deeply.

However, suislide did remind me of why I bought my s14 in the first place and why I now want an SC. I felt the need to step up from my s13 to something more mature (but still sexy, fun & deceptively inexpensive). I have to resist the urge to turn whichever SC I buy into another toy car. So I'm going to limit mods to bolt-ons, suspension/brakes, cosmetics and I.C.E.

 

Doubt it, once you start one thing the list never ends.

 

I have no experience comparing different dynos but power is power. If those 2 dynos are off by 100 well then one (or both) of them is messed up.
I would place money on a sc400 tranny not holding 450hp.
These 2 threads really helped me

The 1jz-gte swap is much more practical and cheaper if your trying to achieve mid to high 400s. You solve the biggest issue when increasing hp/tq, which is the tranny, w58 or stock sc3 or sc4 auto tranny, they all suck. Not to mention you have far less tuning issues since the car is stock turbo, oh did i mention no distributor. Then you also get the right ecu for the manual tranny, which saves a lost of money since most of the 2jz-gte aristo come with the auto ecu.

And on top of that the engine is just as strong as the 2jz-gte, its just has .5l less of displacement and a slightly worse flowing head. But power is stil easily achieved on it.

Look at the first link. This one guy said.
"1jz numbers for me I made 507rwhp and 418 ftlbs. I have the dyno sheet but no idea how to post it.

Mods were HKS T51S
550's
SAfc2 #" exhaust
Thats it."

And their are a bunch more posts like that. I've done a TON of research and the 1jz is just a better swap then a supercharged sc400. It makes a better platform to make more power on. I think your missing MY point. Your comparing a 1uz-fe na-s(or w/e u wanna call your supercharger) to a 1jz-gte/r154 swap. Yes in that example, sure the supercharger is a better buy for the money BUT if your wanting to make more then the 300-350 with your supercharger, the money it takes to get the 1jz to 450-500hp will be cheaper.

 

Stock block 1jz has seen 900 rwhp, stock block 1uz setups have seen more than 800 rwhp (crazy aussies). Engine resilience isn't an issue between the two setups.

R154 can be easily adapted to fit the 1uz, as well as the venerable V160.
Most (98%) 1jz clips/engine sets have the same automatic (A340/341) transmission as the 1uz, so in either case, you have to swap the transmission.

It's also not about PEAK power, look at the power bands to see where and how wide the power band is. The only real downside is that there's pretty minimal aftermarket support for the 1uz, but, if you're going for unique, that's the way to go.
