Toyota Hilux RV8

[Risky]

Hi...back again.
After succesfully doing the RV8 swop into my Hilux Mk3 and enjoying the burbling exhausts I was just looking at a few other options for my truck. 1st ideas was to possibly remove the RV8 and stick in a Lexus 1uz-fe....all very nice and returns it back to Toyota again but I am also toying with the simpler idea of a TVR lump.

So after sniffing around e-bay and realising that there are a fair few differant motors available I decided to seek advice from here again.
My engine is just a basic 3.5 with a Edelbrock (weber) carb conversion rather than the Efi system. All works OK and is fine...BUT, just fancy a bit more Oooomph.
So...what would you peeps recommend as a simpleish swop working with what I already have?

Cheers

Phil.

Stick a bigger Rover V8 in there !!
Thats as simple as it can be

You might as well go for a 4.6 block and heads as the base unit as all your other bits will drop straight back on.
The Eddy 500 carb will be fine with the 4.6 litre engine.

I seem to remember that a 4.6 running 100% VE at 5800 rpm only needs 470cfm?? I'm pretty sure thats right.

So carb wise it will just be bigger jets / needles.

You will be surprised at the increase in torque from a 4.6 over the 3.5 and with the cam timing tweaked a couple of degree's you can shift the torque up or down the rev range to suit your needs.

That will give you a better motor that drops onto your existing mounts as stage one. Then you can alter other stuff for max power tuning as funds allow

Thanks for reply..

Okaaaaay, firstly I am running the truck mainly on the road as opposed to playing at off roading so it's more for the extra power/sound. I was just curious to see that a fair bit of BHP is coming out of the TVR lumps as "standard" (240+bhp)..is that about right?
So if that's the case then it kinda makes sense that if the tuning is internally sorted in the TVR lump then it seems to be a case of drop it in and awaaaay we go, or is that being too simplistic?
I don't necessarily need that much HP running through a Hilux box but i can be gentle on the gas....well try to be!

TVR engine in a heavy truck might not be a good idea. A TVR is probably half the weight so if you get your gearing wrong you might find you have to buzz it a lot. For a truck you should be looking at low down torque rather than high rev HP. Doesn't sound so good in the pub but it will feel loads better to drive.

Hi
as a chevy fan I can recommend,
A small block chevy , bore it +30" put in a neutral ballance 3.875" cast iron crank in it with hyperutetic pistons with a small dish in them, aim for 10:1 compression, and I beam rods, should give you 396 ci roughly 6.5 litres, get it as a kit from the states. Add a hydraulic roller cam of about 212 degrees inlet duration 218 exhaust at .05" on a 112 LSA with a set of aftermarket ally versions of vortec heads, 64cc chambers (but with old style bolt pattern) some roller tip rockers. A set of long tube headers and a dual plane manifold with 4 barrel throttle body running an extra efi controller and coil packs for the ignition. Stick it on an 4 speed overdrive automatic transmission on it, or a suitable manual if you must.
That lot should give you about 350 to 370 bhp, a torque curve flat from about 2k revs to about 5.2K and pull in top from idle to 5600 but over rev to just beyond 6K. it will pull the skin of a top of a jug of custard and could be geared high for motorway cruising.
All those are budget parts and would be about the same cost at a top hatted rover 4.6 build of about 100 bhp less.
Best regards
Mike

And what do you know about motors huh???

jeeez, it never ceases to amaze me the information that just floods from some peoples heads....humbling! I suppose you could be talking utter rolloxs but I'll take the above as a given.
Thanks guys for your info....that's why I read these forums because I find them so facinating what people come up with and what goes where to make poop happen..brilliant.

I'm kinda thinking that LEXUS with standard LEXUS autobox now after being told that a standard half sensible RV8 can destry the hilux box let alone a TVR lump....so I then go back to plan ???? lost count!

Anyone playing around with 1UZ-FE and Hilux's on here recently?
My only real concern with the Lexus is the Electrics and mating the Autobox to the transfer box etc...oh and mounts, exhausts...Hmmmm.
My head starts spinning thinking about it but it just keeps saying GO FOR IT!

Hi
I think the lexus route will be the simplest if you are happy messing around in wiring looms, the cheepest too as a running old lexus is well under a grand. If you are concerned about the transfer box needing parts machining (like the RR case has to) then look out for a transfer case from one of the US 4x4s, they generally are a seperate unit with a prop shaft flange on the input side. I still think a long stroke small block chevy is your best bet, but I am biased!

sounds good, (I'll bet literally too ) but how much would all that weigh compared to a RV8? genuine question. The ally heads you suggested will help but surely must still be a mighty lump?
