AFTER SOME ADVISE ON WHICH ENGINE TO PUT IN MY 240Z. HAVE JUST REPAIRED ALL THE RUST AND UPGRADED THE BRAKES TO TOYOTA CALIPERS.

 

AS I LIVE IN AUSTRALIA AM I BEST OFF BUYING A DONOR 82 280ZX AND DROPPING THAT ENGINE, FUEL INJECTION ETC INTO MY Z OR SHOULD I GET A QUAD CAM LEXUS V8 AND SUPRA FIVE SPEED.

 

WANT ABOUT 180-200 REAR WHEEL H.P AND WILL USE THE CAR FOR THE ODD SPRINT EVENT OR CAR CLUB DAY.

 

CAN SOMEONE TELL ME THE PROS AND CONS OF EACH UPGRADE.

Rover,

Welcome and I am not alone in what I am about to tell you.

Search.

It is a cool button right between register and FAQ up top.

For the power you want, there are about 100 different options...and it has been covered a bunch of times.

Your power requirements are rather low, and a Lexus V8 is a bunch of work,(as noone has done it with a Supra 5 speed before, and only one Z with the V8 at that...but you can find all this by a search).

Happy hunting with your:

Search

Let us know what you find.

-Bob

The 1UZ-FE (a.k.a. the quad cam Lexus v8) is one of the strongest import engines ever produced. There have been people pushing 1800 to 2000hp out of them (I'll grab the link for you later). If you're shooting for 400 or 500, it's going to do that easily and still be a perfect, smooth daily driver.

 

Like Bob said though, it will be a lot of work, where as the 280ZX motor will be bolt-in and go. You have to ask yourself whether the work is worth it?

basically taking a L28ET would give you the power you want with just a little bit of work and its a direct bolt in

 

you can take 200ZR mounts and put a RB25DET in turnthe boost up get a R34 GT-R fmic w/ custom endtanks and a good boost conroller and you'll be set w/ more htan enough power

Your HP requirements seem very low. For the amount of work that you're going to do swapping engines you could have twice the HP for hardly any more work. If you are really considering using the Lexus engine, you might as well work it to put out big numbers.

If a lexus v8 puts out about 280HP stock, what sort of Hp can I get out of a l28 without making the car undrivable on the street. What sort of dollars does that amount to in Oz. quite happy to go turbo if required.

 

More worried about weight of motor than anything else (hence the ally V8). Want my car to handle very well.

 

Lexus motor is about $3,000 in OZ. Found some place that does bell housing conversions for the supra 5 speed manual. Did the lexus have a manual box or just all auto's.

 

Does the l28 bolt straight onto my 240z 5 speed.

 

What about later model RB motors what manual box do I need to run with them.

 

Probable very basic questions but can't seem to find basic answers in these forums yet hail.gif .

 

Thanks guys

The most commonly, and i think only box used with most RB's is the RB25's 5 speed because it is a RWD and lines up nicely, or so ive heard. that would definately be an easier swap then a 2JZ because it has been done a few times and people are starting to produce conversion parts for it. good luck on your search though, the RB stock would give you an awesome little dragster with a z.

You can get 200RWHP (and more) with a high compression well tuned triple carbed normally aspirated L28 or even use the first generation Diesal Maxima crank and stroke it to 3.1L (if these cars were available in Australia) but you will need strong rods and pistons if you take the compression high (10.5 or 11.0 and beyond). Of if you want you can go with 6 individual throttle bodies which would be awesome (more $$) but you get adjustable and fully prgrammable EFI.

 

L28 Turbo sky is the limit based on how much $$ you have to spend. But 250WRHP is pretty realistic for a well tuned L28 Turbo with larger injectors, larger fuel pump and a decent front mount inetercooler and boost in the 13-15psi range. This engine will phsysically bolt into your 240Z and also your 5speed.

 

All Lexus QuadCam V8s are auto and the Supra manual tranny conversion is fairly popular.

 

RB motors require RB 5 speed.

 

Best bang for your buck? L28 Turbo.

all coolness of 2000 horsepower aside

 

i vote for l28 jsut for the ease of install and real world power production capability

 

but a quad cam would be just plain cool...you could put a 2JZ 6 speed on it..instead of teh 5 speed...and not to mention the fact that it can make 600 hp relativly easy?

Look at it this way...

 

When the time comes that you want more power, it would be cheaper to achieve 500+ HP out of the lexus than out of the l28...(if it is even possible to build a 500+ HP l28 that would have any notion of streetability..)

I would go for the lexus just the "COOL" factor...

 

Just my opinion,

Joe.

Here's a simply chart showing a comparison between the two engines.

 

engine_comp.gif

 

As you can see, stock for stock you're already 100+ hp ahead. With a full forced induction setup (#2), the gap widens. Under heavy modifications and very high boost (#3) you can see the difference.

 

The only downside is that the 1UZ-FE will cost a couple thousand more to start out with. You really have to gauge your horsepower goals vs. cost you're willing to pay. If your goal is 300hp, installing a 1UZ is kind of a waste of money. If you goal is much higher than that however, that's money well spent on the 1UZ.
