Turbo: Help me help my mate!!

[Rough_Rider]

I know this has been done to death but im new to the forum. My mate has a tb4.2 patrol swb. Hes lookin at slapin a turbo on it. I hear that the td 4.2 manifold will bolt straight on. What sort of kw gain should he look for and with what turbo set up garrett ect????? Any help would be muchly apreciated.

look in the bible... there are countless posts on this.
just the turbo on its own will do bugger all.. you need to tune it to suit.

I have to ask the question, what gives people the idea it's really that easy?

Mate i know there has to be more involved than that. I have absolutely no idea about turbos and when my mate asked me i said id drop a line on here to see what i could find out. Nothing about modifying an engine is realy that easy. Just trying to educate myself on it thats all.

Thanks for the push in the bible direction tomo.

Try searching for "TB42" and "turbo", or a combination of both. (set the filter to nissan and 4x4 tech too). As said, HEAPS of stuff on here, some pretty good results too.

JFYI, the TD42/TB42 and TB45 can use the same exhaust manifold. You can get them with a T3 flange too. I'd probably go straight gas while he's at it.

-Turbo
-Manifold
-Plumbing (oil/water/air)
-GasResearch TB mixer
-B2s converter
-Gas conversion stuff if not already dual fuel
-Tuned at a workshop that actually KNOW nissan/lpg/turbo - very important.

Thanks Coxy. I must admit im also in the market. But straight gas doesnt apeal to me. Im seting up for winch comps and straight petrol or dual works better for me. Ill keep hunthing for insperation (cant spell). Thanks for the insight mate.

I got the new Engel Winch Challenge dvd the other week, and from what i could hear, there were a few TB42 turbos and possibly RB30 & TB45. I'd say there's be a combination of straight petrol, straight lpg and dual fuel between them all. I'm sure someone will pipe up with more info.

It can all be done, it depends on your buget. If you want duel fuel you really need EFI. From $5000 to $50 000 and from 150 rwkW to 400 + rwkW. A little more info on what you want to acheive.

My mate his hoping for around 160 rwkw and wouldnt care if he went dedicated gas. I am of the oppinion that gas is for barbques and would just rather go straight petrol. Kw gain ...... i dont know realy 180 would be nice. Got a few mates in the comps and wouldnt mind giving them a run for their money but i think i need to get some events under my belt and learn to drive em properly before i put more balls in it. I think anyone who plans on starting out and bringin home trophys is kidding themselves.

How was the engle dvd Coxy???? I was there on the sunday and it was prety full on!!! I am eager to see the dvd. I may have to go out and pick it up.

[coxy321]

It was great! Not a huge range of different trucks (90% were GQ's), but plenty of different tracks, some technical, some speedy, and some with dirty great big slush pits.

There was a HUGE range of different driving styles too - some conservative and some HARSH. Its interesting to see what sort of approach/attitude towards different obstacles proves to be the best.

Go hard or come last is what i figured was best. The DVD is definately worth buying though.

Anyway, back to your question. If your mate isn't stressed about petrol or LPG, search through the nissan forum and see what other people have done. Either way, big power means more setup cost, but obviously LPG will be cheaper in the long run - PLUS theres the $2000 gov. rebate. There's always LPG kits going for GQ's cheap as (under $400), so maybe a conversion, and use the remaining $1500 to put towards a turbo conversion....

For PGS 4WD say how much do you think for 175kw at the wheels, running straight gas, does it help if the car was alredy duel fuel or is all the old crap just crap

[coxy321]

The other stuff can be used, but you'll have to make sure the gas lines have a big enough ID to power "xxx"kw's. If you're going GasResearch you'll need a GR throttlebody and a "B2" (or B2-S) mixer (or something that allows a balance line with positive pressure).

As said earlier, make sure your ignition system is 100% as it is absolutely crucial with performance LPG, and even moreso with LPG & forced induction.

I'll leave the rest up to joel.

175kw at the wheels is, high output ignition (I would suggest ICE ignition) twin converters and twin lines to the tank. I'd suggest Gasresearch. It is borderline on valve springs, personally I'd fit them, about 8-9 psi boost with a stock engine and a decent intercooler. With valve springs it would be good to about 200 rwkw, 220rwkW with a camshaft, beyond that you need to think seriously about a built engine (pistons and rods). Bearing in mind thats on my dyno with SAE accuracy, there are dyno's that will show what you want as opposed to whats real.

sounds good to me deffinatly something to think about, can you give everyone a ruff figure on price.

[PGS 4WD]

It's hard as it depends on quality, a cast manifold or custom, tig stainless or alloy cooler pipes or mild steel painted, or powdercoat, does the lock off and gas line suit as one or the two or are two new ones needed, whats under the bonnet for fitment room, custom air box and so on like duel batteries? The list of modifications to these vehicles is huge abd they can have an impact on the cost. If anyone is interested I'd rather see the vehicle so it can be assessed. It can be done to work, done to work well and done to work well and look top notch, the reality is materials and fabrication time varies depending on the desired result.
You could spend $6000 to $20 000. A lot of our customers do what they are able to do themselves and we finish off and tune.
