3RZ-FE

[johno88]

cause they shit on the diesel, take up less room an effort then a V8 and will shit on a V8 with a snail added plus cost next to nothin

What have you needed to get the turbo going?

-Complete motor
-T3/T4 or GT30r turbo depending on budget
- A custom clutch with ova 2500lb clamp force
-2nd hand cleaned/flowed RX7 S4 550cc injectors
-adjustable rising rate fuel reg
-walbro 600hp efi pump
-microtech LT10s ECU, available with 3rz base map
-turbo manifold
-intercooler or your choice
-3" mandrel exhuast
-assorted plumbing and adaptors from ebay to get everything connected
-dyno tuning time

I think thats it, Once u factor in that you can probably sell ur old diesel, turbo diesel setup for more then the complete 3RZ it doesnt get all that expensive.

You dont hav to do anything to the motor if staying under 10psi of boost, There weak spot is the rods and If u start goin for bigger power (ova 300hp ) then u will need to either decompress the engine or fit forged rods, if u buy a shagged motor to begin with u can get complete forged rebuild kits from the states which r bullet proof.

Cheers

If running say 5 psi would the car run on a stock computer? adjustable rising rate fuel reg, and bigger injectors?
cheers

[johno88]

sorry i mean would they be nessesary?(adjustable rising rate fuel reg, and bigger injectors)
cheers

[Rory]

wont run to well...berad can tell u more bout running them on stock ecu. But 5psi with a aftermarket computer def does get them moving abit better

[a1 mech]

wont run well at any positive pressure ova about 2psi I believe with standard computer will hunt and stall, Injectors will max out about this to so bigger ones r required. I picked up a set of cleaned/flowed 2nd hand RX7 550cc injectors for $200 off ebay which is pretty cheap, apparently hyundai excel injector plugs can be used also if u cant source RX7 connectors. You will need a rising rate fuel reg to increase fuel pressure as boost rises. Berad will hav more info about this im sure.

What kind of final price are you looking at to turbo it.

Would supercharging it be a better idea?

[a1 mech]

either supercharger or turbocharger is a completely custom fit, both will require new ECU, injectors, intercooler and tuning etc to do the job correct, Just depends wat ur preference is, if anything I rekon puttin together ur own turbo kit for it wud be cheaper.

I havent added my whole conversion up but takin into account the sale of my old diesel and turbo gear as well as a few other bits an pieces associated with it, the turbo 3RZ probably will cost me about 5-6k maybe.

Cheers

[Rory]

iv heard of the hyundai plugs for the rx7 injectors, but i didnt need them, my stock 3rz plugs clipped straight on. Have u checked yours to see if they fit?

[a1 mech]

I havent actually, I will hav to check i guess lol

[bendev]

these are a great motor
here are some pictures of my Hilux featured in the ZOOM magazine with a 3RZ-FE





and here is a photo of me torturing it on the dyno

looks the good mate, ur intake manifold is alot cleaner then the stainless one I hav, Mine still utilises the bottom half of the factory intake manifold. Does it effect its response having a shorter distance from throttle body to cylinder?

The only thing bad about those LCE kits is the average joe wud hav to folk out 3mths pay for one lol.

[berad]

Indeed, sites to look at in the us are

lcengineering as has been said
paradise racing also does alot of custom parts eg adj cam gear etc.

Its the same as all kits, there expensive but they are complete and hassle free,

Ussually with intake runners, shorter runners encourage more power where as the longer runners are used when looking for more torque.

ummm TURBO 3RZ SHIT ON A V8 - I DONT THINK SO... Unless you throw BIG $$$ at it. 320bhp from a stock gen3 and being stock will easily outlast the turbo in life..

[hixi126]

its really the difference between a 2 stroke and a 4 stroke , if you plan on running a huge turbo on a 3rz it will be un usable i think , thats why im getting rid of my 3rz

[berad]

ummm TURBO 3RZ SHIT ON A V8 - I DONT THINK SO... Unless you throw BIG $$$ at it. 320bhp from a stock gen3 and being stock will easily outlast the turbo in life..

Not if you dont keep topping up the oil to the busted arse thing

HAHA your obviously a v8 nut , bhp yes, take 30-40% for drivetrain loss and what does it give you.. A gen 3 with a set of extractors aka mild work will be eaten by a turbo 3rz, granted a v8 with a turbo or 2 will eat the 3rz but this is not the debate.

You wouldn't drive a red ss would you haha.

Take mine for example which is now in rorys 4x4,

haltech ecu (could have chosen a cheaper ecu to do the same job), $1600
exhaust $600
Manifold, turbo and lines $700
injectors $150
fuel pump $100
Dyno tune $500 (mines self road tuned)
Intercooling $300 (600x300x76, 2.5inch stainless mandrel pipes)
Custom built clutch $600 (could have bougth a hd for $300)

$4500 roughly, not bad for a 300 (RWHP), car/truck that will be reliable, and 400-500 rwhp for not alot more for dynos and running down the strip, off road the motor never see's positive pressure unless you put the boot into it trying to man handle something, but in saying that the aftermarket ecu is programmed for more ign advance off boost so throws the torque through the roof when needed most, mine made 1050 ftlbs on the dyno (ill upload the sheet if you would like ), i believe this is similar/more than a gen 3. ( no this is not nm). I've never been beaten by any v8, granted i have not raced highly mod'ed ones and trust i will loose, but ss's, clubsports, maloo's, xr8's, xr6t's were never a problem. Power to weight is the winner not bulk wheel spinning meaty power.

here is 3 quarter times you'll find interesting. Three runs stand out 12.4@ 84mph 11.8@ 101 12.3@119 if i can put those 3 together for 1 good one it should be ok

The whole motor including buying it was built for $6500, including forged rods and pistons.

Bahahahahahaaaa.... that sounds like its been read straight out of the text book...

[TheBigBoy]

Im not a V8 nut at all. I dont even have a V8 4x4 anymore. But all the turbo petrol engines ive seen have been unreliable. Stock gen 3 made 320 RWHP and 1100 ft. So I guess thats the bench mark. But remember its stocko.

True, your is much lighter.

[Matt_85Lux]

Not all of us V8 fans think like that. Yes a turbo'd 4 will usually sh1t over a stock V8. But obviously it will have a bit more difficulty if the V8 had the same extent of mods. Also comparing a turbo 4 to a V8 is like comparing apples to potatoes, as in they are two totally different things

[TheBigBoy]

AWW cmon Matt, dont be like that . Im not talking so much about the speed of them. Ive seen alot of turbo 4's, 6's and 8's with mind boggling power. But ive also seen ALOT of them go bang. Thruth be known they where probably done half arsed and on the cheap. But thats why im saying they need alot of dollars to get them right and to be reliable. And have good life.

Berad sounds like he knows what his talking about, especially with those pics.

[Rory]

mine will be on the dyno very shortly, we will see what a road amature tuned 3rz will make b4 a pro gets to tune it.
Yes the v8 may make that stock, and yes they do push a commy well but u have to look at other things,
A. You have to buy a gen3(alot more than a 3rz)
B. Your have to install the gen3 with all assciated adapters, may need modded extractors, twin cross over pipes if u plan on running one system, or more mufflers if u plan to run 2 pipes back. Maybe a diff radiator to keep it cool.
(Im just taking guesses at some worse cases as iv never done the conversion of looked into it)
By the time you have done this, it realy has ended up a expensive experance.
You could do a turbo 3rz abit cheaper if u were pretty handy, and with the inital outlay prob only slighty more then the gen3, it is certainly is alot more work-able later down the track, set of forged rods and pistons(from the states pretty cheap when the dollars good, prob the price of having the heads off the gen3 n some work done).

thats my take on it, and i know this isnt a topic bout gen3 vs turbo 3rz rah rah

[Matt_85Lux]

If you spend 4000-5000 on a 4 turboing it is going to go better than a stock V8. Berad stated 300rwhp on one he did which is better than a stock LS1 (mine stock ran about 240rwhp). But for 1500-2000 you can have just over 300 in a LS1. ei it is cheaper to get realiable HP out of an 8 mainly because of it having a larger capacity to begin with.

ALso I have had a variety of engine configurations over the years:

turbo 4
straight 6
Rotory
V8
diesel4
petrol4

yes they were in diffrent cars but you can still tell the different ways the power would come on, and IMO the turbo 4 had no where near the low down grunt an 8 had but it had better top end than the V8

[berad]

haha as it's obvious the debate could go on forever, i've also seen lots of n/a 8s kick a leg out of bed from people thinking there a supercar, stock v8 rods = not a fan of big revs , if you want me to upload the sheets im more than happy to, im not into having conversations with no experience and/or knowledge of what im talking about.

Which is common practice for this site in this school holiday period.

Come on lets not talk learner plate rwhp figures, show me one gen 3 motor thats stock punching out that much power, its almost laughable.

[Rory]

Matt_85Lux - that may be true, but for that money u could also throw rods n pistons into a 3rz and make more power, and be as reliable as he ls1.
So by the time you have paid for a ls1, then all the costs of the install, then the 1500-2000 on the engine, im gunna put it out there that you would be up with the cost of the forged 3rz, for less power.
The next step in price tho is most likely were the ls1 will produce more power for the $$$

stock 320rwhp? I call bullshit, mine with exhaust and intake mods hasn't even cracked 300 and most likely won't unless it gets tuned. the only way it would have that stock is if it was a C4B out of a GTS/SV300/Senator300, in which case it isn't a stock one as they have a cam and a tune. Also Gen three isn't the designated engine it is the engine design

So Gen 3 design covers:
LS1 - 5.7L car engine
LS6 - 5.7L car engine
LQ9 - 6.0L truck/SUV engine
LQ4 - 6.0L truck/SUV engine
LM7 - 5.3L truck/SUV engine
LR4 - 4.8L truck/SUV engine
LM4 - 4.3L medium size SUV/SSR engine

But seeing as most people assume that an Gen3 was the motor in the vt-vz range I assume it is an LS1 you are talking about

[Sic Lux]

So how did last semester go for you also in this carry on who's running a gen 3 in a lux or you guys just talkin numbers

[Matt_85Lux]

That right, as I never thought of the install costs till your other post.

But that being said IF you were thinking of a late model 8 why go an LS1? I have one in my SS not he best motor for a swap, I'd go a toyota 8 or if you wanted a chev the L98 from a VE. And to put one in I'd be budgeting around the 10g mark anyway so the 3RZ turboed is a much cheaper and easier conversion

[Rory]

oh the ls1 was just a example as old mate b4 was rattlin on bout them.

[Matt_85Lux]

fair enuff

[TheBigBoy]

Stock as a rock apart from extractors.... After I fixed up the air flow and a few other bits it made over 300. There is/was a difference in hp figures between the import ls1's and the aussie gen 3's. It was a VY ss engine.



Budget, yes ofcourse the turbo 4 is going to be cheaper. I spent a rediculous amount of money on my engine as it was 1 of the first in aus. But almost all the turbo petrol 4x4's ive seen compete or at the parks have stuffed the engine/turbo after a year. Otherwise thats the way I would have gone...

Rebuilt aussie gen 3 stock everything..
