1st Gen Rx-7 owner here. For all my Rotary haters, I have almost 200k on the original unopened 12a with years of hooning under it's belt. Love the build but I will never put anything but a rotary in my Rx-7. Good video David!
EXTREME SCALE PERFORMANCE RC I also have a rotary engine on the other four cars. I have a 20B rotary and 13B rotary ! I just decided to do something different.
But that's what you need to do with a rotary, you need to hoon and rev the hell out them regularly or they don't get the oil feed they need. Can't drive around at 1k rpm and expect them to last long.
cody roland Exactly. People treat them like piston engines and baby them then wonder why they don't run for shit or last long. I let mine warm up for a good 15 - 20 minutes before driving and always walk it up to high revs even when cruising. Redline a day keeps the carbon away 😎
1UZ engines will never make LS power, but you sure can’t beat the refined smoothness, the way they sound, and they way the power ramps on so linear. These engines are masterpieces!
Great video sir, 1UZ is probably one of the most underrated V8's out there... very light weight and can clearly support a good amount of power! That fuel pump is why I've always like running MKIV Denso fuel pump(s... if you need more fuel). They're quiet like a factory pump but keep up or outflow the Walbros etc. I had a Walbro (whiny-bro) 255 in my first RB swap and just couldn't do it after that...
stefan samotulka no I know these engines are super reliable I'm a 1uz fan I love the 1uz engine I was just telling him that they wasn't putting n/a 600+ hp engines in cars in the early 90s
I've seen some nice 240SX 1UZ swaps on youtube. If only the Lexus 1UZ and Nissan VH45 had more aftermarket support these engines would become more popular for swaps.
It's actually not to bad if you know where to look. There are many options for tranny you just have to drop a few $100s to get the bellhousing and adapter made.
I agree! I had one and wanted to swap into my HACHI until I realized how shitty the aftermarket support is. don't get me wrong there is some support for it but the price you gotta pay for it is kinda high. yes I understand you gotta pay to play. but hard when there is other RWD engine setups to run that's more affordable. and depend on what country your in also. good thing is if you do swap it in something you could blow it up every weekend lol because they are easy to find and relatively cheap or free to obtain. lol if my pockets was deeper I would make one for my HACHI.
then why doesn't it make any power? A LS 4.8L will make 425hp with just a $300 cam swap, this needs turbos to keep up with N/A push rod 2 valve engines
and a 4.8L is 4.8 liters :/ but with a quarter as many cams and half as many valves and it actually gets close to 100hp per liter unlike a 1uz which should because DOHC 32v but no :(
I'll be Frank I'm Leary about using my name, 1uzs are plenty capable of 100hp per liter. This 1uz makes 150/liter, you can do that on a stock 1uz engine, ive seen more. But so can an ls. The aftermarket is bigger for an ls though which makes it easier. 425hp with just a cam..thats not likely. To get that you need supporting mods as well, headers, exhaust, intake, tune, etc. Both great engines.
I'll be Frank I'm Leary about using my name, another funny detail, 1uzs in the mid 90s were making 290hp and 300ft/lbs, while the 4.8 when they started in the early 2000s made 275 hp and 285 ft/lbs. Hp per liter right? Or was it the valves..? Now im not bagging on the ls series, great engines. But the 1uz is one of the best. I own one with 250k and factory compression.
People can say what they want, but with a small aftermarket, people were making 1000+hp with these small displacement V8s years ago! I remember a Australian build back in 2014 that was making 1200 with a restrictive manifold and some other stuff that could have been better. They were planing on changing a few things and getting 1500 out of it. It's capable. Light and can last a good bit. Say what you will, but if you have to compare this engine to a 6.2L or any other big displacement V8, clearly the 1uz is doing something right. Also won best engine award.
your right. I mean it was my excuse on why I decided to not use the 1uz. but then it comes down to time and money. with the right amount of money you could make a 3 cylinder geo fast lol. or could be like some of the aussie guys and fab your own parts which is mad respect! but takes time. the thing I like about the 1uz is like you said its the smaller v8 of the world lol which makes it so much better when you beat people with bigger more expensive engines lolJUST MY OPIONON
The 1UZFE is an underrated engine, it can get expensive to build though since parts are usually hard to come by. I have an SC400 that I really wanna stuff a W58 or 350z 6-speed in to, but at a swap cost totaling around $5000, I don't know if its worth it. I could just put that towards a Mustang or a 370.
I don't think so either. Idealistically I'd do the swap the right way and put in an LSD to match the transmission which will probably add another 1000-1500 and none of that is taking into consideration the suspension and tire setup I'd like. Ultimately, I'd make the SC4 into a driving enthusiast car... maybe one day if I ever have a few thousand dollars burning a hole in my pocket.
UZ is a great plug and play engine, here in Russia it is significantly cheaper to get than an ls, its very reliable and those 300-400 hp these engines make is stock form is plentiful for a street car. But if you want to get more it’s going to get really expensive very quickly as there aren’t many aftermarket parts available
I love this old rx7 reviews keep em coming, a little upset I didn't get to hear that amazing brap brap brap from the rotary but still a crazy cool build and it's Mint! Love it
I'm a 60 yo male petrol head from sydney Australia my daily is a 1uz with a tr6060 in an e30 and LINK computor, I also run a standed e46 m3 as a luxury car for social events. Though I think your a nice looking young man and a cool guy I would prefer to look at my wife for that amount of time. perhaps in a few years when your not so photogenic we may be treated to some proper car camera footage. other wise good feed back from a timid driver which is completly real and honest so yep i will persist with more of your reveiws at the same time hoping for more.
All that power and yet you smiled and laughed way more in your first FB video! Proof, a rotary is unlike any car you will ever drive. I have an FB and it makes me smile evry time I drive it! Keep up the great videos!
These reviews are getting hella boring. The least you could do is get some exhaust/flyby shots. Watching you just talk the whole time, so meh for a car review.
great video! it deserves more likes! also i miss the beginning glamor shots, i know it gets repetitive, maybe you could throw it in the middle of the video while youre driving describing the car.
Was doubting the car cause there's no roll and and no slip proving it's running 9s... no idea what track would even allow this. Hearing it spool up and go it sounded beautiful though. Beast none the less
I only reason I like this video is because it doesn't have an LS in it. I love my RX7 with their rotaries. But since this isn't just a usual drop a deuce LS and go I appreciate the craftsmanship
I’m currently in the work of getting David to drive my 1990 st184 gts with a 3sgte gen 4. Having to finish up some repair work but will try to contact him shortly after the car is good to go.
GhostAlpha10 that's sick I got rid of my Celicas one was stock 2.2 the other a GTS with a BEAMS swap and now I have a DA9 Integra. Is it terrible I miss my Celica so much more?! Can't wait for the review of your car!!!
I think I heard some compressor surge (not the good kind of turbo flutter) at 3:23, and given how David reacted (immediately shifting and easing off the throttle a bit), I'm inclinde to believe even more so. How much boost and HP is that thing pushing. I can imagine that the stock block wasn't handling it that well, especially considering what Dave said about the previous 1UZ blowing up. @ThatDudeinBlue
For starters a seven without a rotary is like a R34 GTR with a Honda B series in it with out boost. Secondly I’m not a fan boy I’ve never owned one (too much up keep & no where to rebuild one) but I do appreciate the engineering concept. The smoothness of the operation, The HP Per liter, size, power to weight Ext. Thirdly reliability is what you make it. if you suck building engines then you’ll suck at building a “reliable” engine. & to the guys that built it. Reliable was what you were going for good job. Only what u guys think counts. It’s you money & idea Just not my cup of tea..
Had a 90’ LS400 with the 1UZ that I drove back in high school and college years ago, great reliable engines. Also the FB rx7 looks great. Thanks for the review david :)
my girlfriend gave me the same hoodie for my birthday a couple years back theyre really nice and soft and very warm, i love it. they come in many different car lines, supras, wrx, skylines, silvias ect
David you should come to Australia, and Review all the MCM cars, the Honda Swapped Mini, Super Gramps, Double Unicorn, The Mira. So many cars to review
