Is this V8 a good deal???

[FJ40Boy]

An the gurlz like the vibrations going through the car when the V8 is rumbling

[adventures_more]

on a bike you mean , chicks love sittn on a road bike that vibrates , probably reason that sit on the back near the exhaust pipe-lol

Gents, maybe a bit late posting but FYI

The Lexus V8 can be run with a factory computer with a manual transmission, some earthing of wires is required but it can be done just like a Nissan VH41 VH45 can be done. The Lexus has a removable bellhousing on the auto trans which could possibly with an adaptor plate be changed to suit the cruiser pattern, just a thought.

Chevs into Land Cruisers go well, Adaptor kits can be purchased or you could obtain a chevy steel bell housing and either one run a three speed cruiser box which would only require a spacer plate between gearbox and bellhousing for input shaft clearance or a special plate and spigot to get the 4 speed to fit. Just other options.

Autos go well but can be expensive to set up. LS1 is a great Engine but you incur additional costs with the Engine management as the Anti theft removal will cost approx $400 minimum, and then if you want to get rid of the need for Vehicle speed sensor, MAF sensor etc the cost keeps going. Ongoing from this the earlier chev bellhousing will fit but there are more bolting points on the LS1 around the bottom, I assume for strength against the aluminium block and the offset of the flexplate/flywheel differs from earlier chevs.

Please also bear in mind that the old chev could be fuel injected (TBI, TPI) at a later date. Another consideration could be to use a holden 304 V8 not bad torque rumbles ok and seem to get most stuff for $2.5k, also available in chev bolt pattern around the bellhousing. I've seen a holden V6 3.8 go well in a FJ40 cruiser to believe it or not and a super 6 is another option but can get expensive also.

Anyway regardless keep your overall gear ratios (Tyres/ diffs/ transfer case/ gearbox) in mind in whatever combination you come up with as disappointment can come from mismatched combinations.

Just my 5 cents worth

everbodys 5 cent's or 2 cents is better than none at all , everyone generally has different experiences & knowledge , put it all together & the info is mind blowing,

Fclass , your right about combinations , in my book anyway mate. the V6 holden ( Buick ) engines can be picked up so cheaply , remeber when i was living in Brisbane, this one bloke would thrash them , buy another for a few hundred bucks and go again- ,

I am startn to realise that its better to have a petrol engine here in NZ as you have on road diesel tax's , lpg is near $1 ltr ( LPG injection ), etc , But most car manufacturer's are realising the potential of diesel, reason why theres alot of development going on recently in that area. I personally think 4x4's are better off with diesel's as set up with snorkells , etc - they can run under water, mud , less hassle with ignition parts , have a longer life span between rebuilds , good for towing/grunt & economy .

I could be gettn a latemodel Jap import petrol engine foi my bundy !

LEXUS RULE I've have one in my fj40 best thing I ever did get rid of those cast iron chev rubbish,way easy to fit with factory computor I did the wiring myself never played with fuel injection before.I'm using the lexus auto with a landcruzer transfer case hilux diffs 4.5 ratio its awesome power compared with the THREE Chev v8's I had in it before as for Skids comments I've never seen him putt around anywhere I always thought his throttle was weld full open LOL a skid

[FClassOutlaws]

Thats great that the Lexus works for you but I assure you a decent Chev will rip the arse out of a Lexus V8.

I am running a Fuel injected 383. Does your lexus wheel spin in top gear on the tar seal in high range top gear with 4.1:1 ratio diffs and 34" tires I doubt it..... Skids wagon performs well as far as I've seen, a pitty your previous engines were not up to the task.

In comparison to the Lexus unfortunately unless you ratio down they wont get up on the cam, they lug and do bugger all. Just cause a motor revs doesnt mean its making power.

[Cruz]

Yea can spin did it at the Motorshow at Mystery creek brunout pad on Kumho 35x12.50x15 got the crowd going then specialy in 4WD

[FClassOutlaws]

Compare apples with apples.... 4.5 is not 4.1, I'm talking high range not low range, no wheel brakes, no line locks just acceleration. Open road acceleration top gear I dont think so, burn out pads are a waste of time. Enjoy your lexus

[MNC]

Yip I've heard the lexus lacks a bit of power unles you get the revs right up there. Solution is to supercharge it

Also already has fuel injection which helps when you are a mechanical retard like me

Check out Jono's supercharged Lexus - its farkn fast And can spin em up with the best of them

[Furgus]

Thats great that the Lexus works for you but I assure you a decent Chev will rip the arse out of a Lexus V8.

& that's why the D-class trucks that win are running chevs.....................

[FClassOutlaws]

Like I mentioned in my earlier post compare apples with apples and yes I see the winning D Class has a lexus v8 in it dan cowpers and have you noticed that the two following trucks of similar shape run supercharged v6s not lexus's, I had a lot of involvement in their design, not that that will ever be publicly known.

Just to concur remember your overall ratios the Lexus is not the be all and end all that people think it is if it works for you good on ya, but they are not low torque engines which is what is needed. The supercharged v8s I have seen on the rally scene are pathetic and that does include a lexus version.

I could go on about this topic chasing my tail wasting my time But I've got better things to do than to try and explain how things work ratio calculations, expected power output, power to weight blah blah. But I agree the only way to get a descent torque range out of a lexus is to supercharge it.

Funny though lexus has the same stroke as a 327 chev.....

Just for the record watch out for D class chevs next season the LS1's are taking off.....

[Furgus]

have you noticed that the two following trucks of similar shape run supercharged v6s not lexus's, I had a lot of involvement in their design, not that that will ever be publicly known..

Yep I know what the other Cowper buggies run they're NOT Chevy V8's

Just to concur remember your overall ratios the Lexus is not the be all and end all that people think it is if it works for you good on ya, but they are not low torque engines which is what is needed.

Yeh right Graham K's truck is apile of kak

btw who are you?????

[FClassOutlaws]

They were going to be chevy v8s, but their are some issues around using them, such as length but given that the vehicles would be perceived as a cowper design I limited my input as I'm working on a project to promote the GM engines further, dont forget about Wayne Osmond. if you remember Stealth or know of the vehicle then you'll know who I am. My user name should give that away.

[Mattman]

Well this thread started as a repower question for a road legal truck not a comp rig so cost and a bunch of other factors are important.

If we go back to the original requirements and look at it again, in my opinion you cannot get a better cost benefit ratio than the Lexus V8.

The cost of installing an injected alloy block quad cam Lexus will be the same as running an old iron block carb'd Chev or Holden. Not to mention that the fuel costs of a street truck are worth considering and the Lexus motor is pretty economical, certainly more so than a carb'd Chev or Holden.

The power outputs will be the same except the Lexus makes it slightly higher up the rev range but the thing to remember is that these power outputs are still well above the factory motor's that are being replaced and the weight advantage of the Lexus only helps the power to weight ratio.

You definitely do need to gear your trucks down to run the Lexus but if you are doing a motor swap then the gearing shouldn't be a problem to also sort out.

If you have the money to run an LSx motor then go for it, an injected alloy motor with 260+kw is wicked but that will cost a ton more than installing a stock 190kw Lexus.

FJ40's are pretty light in comparison to full body trucks so the Lexus makes a great swap IMHO reducing weight even further.

Anyway, at least we all agree that V8's rule!

Matt.

[FClassOutlaws]

Matt thanks for putting that back into perspective, in regards to the holden engine I was talking injected for the cost. The Lexus is not that light, the block maybe alloy but the top end has a few more cams etc. Yep road going their ok.

[petefj40]

has anyone seen how much you can by a second hand LS1 for these days? One that's done under 100k will set you back just over $3k. That's almost half of what I paid to by my one. Mine was out of a VX SS ute that had done 66k. But I know you can buy a Lexus V8 for less than that. In saying that. Has anyone heard the specs on the brand new V8 Lexus they have in the latest landcruiser? I think you'd be surprised.

Pete your a grave digger

[petefj40]

Pete your a grave digger

So did you buy that LS1 you were raving to Rick about PR?

(I'd say, no)

[PR]

No it had a bad piston slap might just have to buy a Jeep Wrangler

[petefj40]

No it had a bad piston slap might just have to buy a Jeep Wrangler

Ah piston slap is easy fixed.

I do like Rick and Nic's Jeep's though. Throw a LS2 in em and I'd be keen.
