Turbo Diesel Sierra

[Graphite Moose]

Does anyone have any info on installing a Mazda RF-T 2.0L into the Sierra?

[Reedy]

No!!!!! Thats a different one!!!!:o

[Graphite Moose]

What do you mean Reedy??

[grimbo]

the main one that has been successfully used is the VW 1.9 TDi. These were done in the US as thhey had the engines and a company called keltec made a kit.

In my opinion a DIESEL IN A SIERRA ISN'T THE BEST ENGINE SWAP. THE WHOLE THING WITH SIERRAS IS THAT THEY ARE LIGHT AND (damn caps lock) perfrom better with a light revvy engine and gearing. By chucking a diesel engine in you get a heavy engine that throws the balance out and lightness goes as well. Then on top of that you have an engine that just isn't suited to a Sierra.

We had a guy in our club put a Gemini diesel in. he doesn't have it in anymore as it just wasn't a good engine option.

Stick wih the tried and true 1.6 Vitara engine because it works or if you want something different try the 660cc turbo out of a Cappucino. they absolutley rock in a Sierra we have one in the club and it is awesome

Good call Grimbo, I had not considered the weight!

Just after more torque really. Im running 30's on it and it just seems to run out of puff, normally 3/4 the up a sand dune!!!!!.

Do you think the 1.6 efi is worth the extra hassle vs the carby option or should I forget the engine altogether and re gear the transfer case????

[grimbo]

you need gearing not an engine change. By putting the larger tyres you've affected the overall gearing of the car. By getting transfer case gears of arounf either 4.9 or the 5.14 it will make a world of difference. Also alot cheaper, easier and legal

[Reedy]

What do you mean Reedy??

I just hav'nt heard of putting that kind of motor being put in a Dook and as I said it would be different!!!!

But I agree with Grimbo, I've got stg3 Rockhoppers in mine with a basically stock 1.3 appart from extractors and 2" exhaust and it has no dramas pushing mine around with 31x10.5x15 Maxxis Mudder Buckshots!!!!!!! I'd go reduction gears first bud!!!!:thumb:

Or you could get a GTi swift motor.

I did this and it screamed. Very good choice. All up about $4000 incl motor.

[Graphite Moose]

Thanks for all your advice, I think I will try the gearing first. Its such a reliable little donk, it would be a shame lose that.

I bought mine with it in there already, whole thing cost me $3000 :D

That long wheel base would be a good thing still, it just wouldn't act like a normal zook because it is heavier and has the conversion gear so probably a better hilux in esscence.

[Smithy's Suzi]

na sorry mate, don't know anythin about that conversion

[cj]

Does anyone have any info on installing a Mazda RF-T 2.0L into the Sierra?

No, but it was a standard fitment to Vitara's and Grand Vitara's overseas. I was recently considering this conversion for a Vit. I have driven a GV with one fitted to an auto and it actually went pretty good. The downside included trying to source a front cut (seemed to damn near impossible) and they are renowned for cylinder head problems. This appears to be caused by cavitation and I believe I had some solutions for this worked out but the $$$ were starting to add up. As pointed out it really is a weight issue in a Sierra and things like the Vit 1.6 are such a relatively easy and well known conversion that works it is hard to go past it unless you have good fabbing skills and want a particular engine. We have an SR20 in one Sierra in our club that works nicely. I know of a VW diesel conversion being done but it is only the 1.5 (I think) but it delivers so little power I don't think it is really worth it IMHO. The VW 1.6 & 1.9 are not common enough here unlike in the US. The Jimny has a Renault 1.5 diesel in Europe which would be nice as these have a relatively good power to weight ratio(can be easily tweaked) but again not a common engine here. We had a member who had put an Isuzu diesel in his lwb Sierra but I always thought it was too front heavy and the same goes for one that put a Gemini diesel in a swb. As we get more of the modern diesels in small cars they may offer better solutions down the track.

I did the Isuzu 1.8lt engine into my brothers SWB sierra that Grimbo and CJ talk about and I tell you what the only reason it came out was that the engine was too unreliable and sourcing a replacement was not easy as they were getting to old.....

Apart from that the engine did in no way unsettle the SWB.....in fact it suprised quite a lot of people when the added weight saw it climb places other cars struggled to climb.....Yes it had stiffer springs in the front to handle the weight but the car flexed and drove everywhere you pointed it........

Apart from reving hard on road it was an absoluted gun offroad and would still be there if the head gasket didn't fail on it's second trip out after being replaced

At the end of the day he went back to 1.3lt sierra engine cause that is what I took out of my LWB sierra and it was cheaper than another head gasket ....

Extra weight up front did not unsettle the sierra if you have the right springs in it....

Are there any lightwieght alloy blocked diesel engines that woiuld suit a sierra?

[Dave_STR]

You could possibily use a Nissan CD20ET out of a U13 Bluebird, get a front cut. Use R31 CA20E engine mounts and gearbox. The CD20ET is a diesel version of the CA20E.

Option 2 is a LD20 out of a U12 Bluebird and use L20B engine mounts and gearbox out of the old Datto's. There both cast iron blocks, but wouldn't be that heavy.

Thats funny cos I was looking at and measuring an L20B with a 6 cyl Datto auto box with a 4 cyl torque converter!!!! I use to own and rally a Datto 1600 running an L20B and my brother has heaps of motors and parts lying around so the cost is going to be very low!!!!! I know its not a diesel but I thought I'd let ya's know!!!!:thumb:

[Marc 1]

Fiat do an alloy blocked 1248cc litre common rail TD, outputs are 66kw (about the same/a little more than stock) in power so no real win there BUT, 200Nm @ 1750rpm - about double standard torque. So torquey and light hmm nice. Backed by a 6 speed box too so it wouldn't be screaming its head off on the highway. Not sure if you could use this though as its normally a front drive unit.

The catch is they have only been imported into OZ for the last year (Fiat Punto). So you may have to import from Europe $$$.

[GRPABT1]

Sounds expensive, wouldn't want to ask the price for parts.

[Gadj]

I wouild like to know what 3.1l donk was used in that lwb monsta (Isuzu?).
I have long dreamed of putting a 4JB1T 2.8 turbo into a lwb sierra as I have experienced the performance of that engine.
I would like to hear if it has been done & how it went - I doubt I will be able to do it myself for some time - money is my biggest hurdle for now. Just had a carpal tunnel release opperation & haven't been able to work for a while.

[GRPABT1]

A diesel sierra isn't really a good thing. There are kits available for VW turbo diesel conversions but those engines are rare on our shores, I think they are 1.9L engines.

The sierras suit a high revvy motor like the 1.0L, 1.3L and 1.6L suzuki motors. What you loose out in torque can be gained in gearing.

The only reason I can see for a high torque motor like a diesel or V6 etc in a zook is a rig running 40"+ irocks and full exo cage etc, and then it won't drive like a zook anyway.

I suggest you get the lowest transfer case gear you can find then get road tyres in the size to suit, you'll be surprised.

[rustyzook]

1LTR motors aren revvy lol there clunky!

[GRPABT1]

1LTR motors aren revvy lol there clunky!

That's probably from all the rust in your piston bores lol.

[rustyzook]

LOL hey i layed it over the other day and it dosent tick anymore :D

[GRPABT1]

LOL hey i layed it over the other day and it dosent tick anymore :D


Maybe it finally got some oil up the top end for once lol.

[rustyzook]

lol funny i say that i just drove it to moonbi to see a friend and its tickin agian! lol

[cac]

I wouild like to know what 3.1l donk was used in that lwb monsta (Isuzu?).

thats my guess....the diesel out of the early to mid nineties jackaroos was a 3.1L....i can't think of any other 4 cyl diesels of that capacity off hand....
