Outer Limits 4x4 Board

No tuning required, just turn the pump up half a turn on the fuel delivery screw. On the dyno I achieved 90 horse power at the wheels (37" boggers) 1900 foot pounds of torque, which calculates to 170 horse power at the fly wheel at 2400rpm. 3 pound at idle and 8.5 pound at 2400rpm. Waist gate will not work on a blower because the idea of a waist gate is to let excess exhaust gases bypass the turbo, which stops it continuosly boosting and destroying itself.

The year of the Toyota Supra, I don't know. Just go to a wrecker and ask for a 2L supra blower.

These two Types your after the bottom one.

Toyota SC12 From a Toyota 4A-GZE, 1.6 Litre SuperCharged Engine.

Toyota SC14 From a Toyota 1G-GZE, 2.0 Litre SuperCharged Engine.

If you are going to the effort of fitting a supercharger - fit an Eaton M90 from a Commodore or a Buick (better manifolding and bypass). They can be bought new $2900ish or good second hand for $500 to $900 (check out Parts Peddler magazine for ads). I have one new one in stock... anybody?

The M90 is a helical rotor design which is much more efficient than the Toyota, and their flow matches the TD42 motors much better. If you want big grunt you can run them up to 14000rpm which gives just over 600cfm. Also, you can buy different noses for them to make the mounting more flexible.

I was going to supercharge for torque and turbo for power / fun (like a Detroit truck motor), the transition could be handled buy adding a A/C type clutch on the supercharger pulley...

If you are stuck on the Toyota idea - don't spin them too hard because they destroy their seals easily (or maybe I was just abusive). Castlemaine Rod Shop sells Toyota based kits for Holdens etc but they might be worth a call, or SSS Automotive in Sydney have them in stock.

Ive got a Turbo in my Patrol92 and if you drove a standard then a turbo one i think you will get a turbo by next week i run mine at 10psi and it keeps up with some holden v6 with 35 muddies and i can also smoke 35s on the spot but i think they a wearing to quickly to do it any more so no more smoking 35's

cheers WHITTY

Have started some chasing regarding the blower option. Available readily in Perth, prices started at $330 plus freight. I think I like the idea so will probably go for it. Nissan is not a daily driver so I can afford to take the time. I will try to take pic etc as I go throught the process.

In your research, did you happen to get the engine codes of the variants that have superchargers? The two 4 cyl.'s mentioned further back surely couldn't be as good as the 2.4 six cyl. variant, could it??

I too am looking at this seriously but am still looking for info regarding what the standard drive ratio of the blower as well as the power characteristics of the original motor. In a small petrol six, it'd have to rev to 5500-6000 rpm, Marko had his setup at 2:1 and Peter Christie had his set up at 2.8:1.

I never rev mine past 3000rpm so I think I could drive it at 3:1 and still blow less than some the turbo's I've heard about.

Anyone else got any suggestions/advice?

P.S. $330 is a good price, I've been quoted $385 for the unit off the 2.4 litre 6cylinder.

yea then go beggin for a Dtronic...

Was talking to AWILL about this last night at a club meeting.

One thing with blowers, on downhills, they aid the car in accelarating even on no throttle, as they are always boosting..


Just a thought.

Remember he has a Shorty so it would go pretty good I would think on the M25.

I am pretty sure the two Toyota blowers have a clutch type arrangement like a aircon that is vac controled (dont quote me) or controlled via a sensor anyway that can be fiddled with. I found this on one of the zuk forums when looking for S/C 1.3's. It has something to do with either not providing boost at idle or it comes of boost once the vehicle hits coasting speed one of the two I can't quite remember.

thats a good answer to a good point. i was wondering what the deal was with enging braking.

thats a good answer to a good point. i was wondering what the deal was with engine braking.

the stardard ratio the toyota rans 1:1 ratio and has a clutch arrangment on the pulley system. Ive removed that and machined up a 50mm pully.Im runing 2.8:1ratio.I suggest you dont run it any faster than that as it will become ineffeiant and most likley destroy its self. The bearings are little pissy things on pulley end and are only grease filled. Do you want to put it on a diesel or petrol?

Bigbluemav,
To be honest I never really looked at other options past the 2L blower, they were quite common when I spoke to the wreckers - I found 3-4 in about 5 phone calls. I saw Marko's setup in Perth at the comp and it appeared to be fairly straight forward - so will see how I go

I also had a look at his set up looked sweet and went realy well is it true that post 92s had a seperate pulley driven vac pump never new that while we are on the subject dose anyone no of a company that sells electric vac pumps
when you say you machined up a pulley for the super charger and puley of the crank did you make new ones or modify the old ones and if so what belts are you now running are the pulleys tooth driven or v belts

Any updates on this subject???

It was suggested that I look into the SC12 / SC14 on my TD42. Must say the idea is VERY appealing.

How about reliability?

How does a supercharged diesel drive compared to a turboed? Smoother power / torque delivery over more of the rev range?

But you're already squeezing every horse out of your engine, hence the sad condition it'll be in if it ever makes 500,000km.
But if I turbo intercooled my TB42, you'd be the one under powered

We got a couple of blowers of a 4agze soarer if i recall. Stuffed if i can work out how to fit them. In the end even though you have all the exhausts, snorkels etc it'll makes a little difference, but not not a whole lot, especially if you run 35's. Putting twin thermo's on it helped without the clutch fan, but still more oomph! Trying a turbo off a ZD30 now with intercooler.

How do you quantify that statement you know someone that has tried to squeeze more out of a ZD30 without success?

How many ZD30's you seen at 500,000km in poor condition?

How do the 3 litres go without a turbo & intercooler?

Wouldn't have a smick but I would suggest like a 4.2 aspirated a slug.

Your Question was in relevance to what ?


You summise that bombing a 4.2 to go harder than a ZD30 is going to guarantee you 500k out of it I suppose?

So why doesn't Nissan do just that to compete with the Yota Direct Injection 4.2TD?

Yeap, much stronger motor built well for milage. They do a 4.2 turbo still
AFAIK, as the ZD30 isn't as good towing and still a new kid on the block as far as long term reliability goes.
There's no subsitute for cubes, if comparing a 3.0litre to a 4.2 litre and saying one is underpowered it should be done either both without turbo & intercooling or both with. I realise there are some design enhancements in the Valving etc, but think the ZD30 would have to be over 3.5litres to be on the same field as 4.2TDi.
Why didn't the 2.8TD kill off the 4.2NA?
Why didn't the RB30 kill off the TB42? It's a more advanced design too.
Nissan probably is quite happy with it's 2 motors aimed at different markets, commercial is going to be more interested in a 100% proven reliable product even if it doesn't have sportscar feel to it.
500,000km out of a 4.2TDi is no problem.

AGREED. TWO DIFFERENT ENGINES. TWO DIFFERENT OBJECTIVES. NOTHING ALIKE

if u want performance ... u can get what i have ... and many others have
T3 garret turbo(same as VL) get a hiflow kit put through it .. prolly $1.5k for hiflow kit .. duno how much the turbo is

custom intercooler big! .. prolly get one of these for a $1500

3" intake pipes

3" exhaust

good for 15psi boost

and good for a giggle when u burn the 4bangers off at the lights

you had to get custom turbo manifold ?

Luke you pull off the safari shiz?

dreamer you own a jeep - get over it!!! and diesels - performance in the same sentence the mind ponders how many dreamers own patrols.....

its a safari kit i have ... they supply the manifold

still got it singo ... i just got a bigger intercooler ...

so if any one is lookin for one in the next few weeks i have one forsale

one off a safari kit ...

Thanks for the link. Interesting article although to me it did seem a little biased. Did it read this way to anyone else?

I wonder how the SC14 would fare against the Sprintex?
