Turbo the 2H

Joined: 22 Aug 2005 Location: Eaton, WA

I want to put a turbo on my 60 series. It has the 2H engine. I only want to run a few psi as a slight power increase and better economy. Roughly how much can i expect to fork out and what for? I know i need the following (may or may not miss something so please enlighten me if i do): Turbo, turbo exhaust mainfold, timer, intercooler (is it gonna be necessary?).
I'm going to get a friend to fabricate dual snorkels for me. Will 60-80mm tubing be enough to feed it as i know ARB wont fit snorkels to a turbo'd engine (according to catalogue)

single snorkel will be fine

probably about $3grand for someone else to do it all, you might be able to get a kit for about $2grand and do it yourself.

exhaust will need at least a new engine pipe made up, a full 3" system would be better

pyro guage, so you can monitor the Echaust Gas Temperatures.

If I'm only running 3-4 psi (heard that'll be enough), will I need the pyro guage? Does it just tell you exhaust temp?

I was getting dual snorkels anyway cause i want to Very Happy

2 grand seems like a lot to only run 3 or 4 psi.. once u get it on there u may as well make the most of it.. pyro isnt nesicary.. just get it tuned by a profesional.. intercooler isnt necicary if yr only runnin low boost.. pretty sure these motors can handle big boost no worries like over 15 psi??
i run 10 on my lux with no cooler and its fine...

2.5 as a minimum or some will say 3 inch zaust alll the way from the turbs.. timer isnt needed either, but its only another 100 bucks so what the...

duel snorkel = ghay.. spend the money on somethin good! if u like twin shit get twin lockers, or duel transfers...

wont handle 15psi too well, anything over 9psi would be pushing it due to indirect injection.

id probably run 9psi, very easy to set it up for 9psi.

pyro guage isnt necessary but helps diagnose problems before they cost you a new engine.

Nooooooooo. Big boost on the 2h, no intercooler means melted pistons. Even with intercooler, the lack of piston skirt cooling means the motor will suffer from thermal stress.

Having said that, I am running 13psi of boost, and have a large front mount intercooler and have had no issues to date, even though so many people said "don't do it." I think the 2h's are a little hardier than some people give them credit for. Important thing is when setting up the turbo properly is that you don't over fuel them. My 2h goes like a cut snake, and never overheats.

I wouldn't be bothered setting up the turbo if you are only planning on running low boost, like 4psi. For the $$$, you will be extremely disappointed in the power gain.

You can run 17psi of boost if your turbo will produce it, no worries....just a 2h wont have a real long life span if you plan on making it a longer term solution.

I was just wanting something that would behave a bit better on road (acceleration and hills) yet not overdo it off road. I didn't want something that would cook itself whilst off road doing some harder stuff. So, wont be going high boost but may go up to 8 or something. Not sure yet.

Also have plans on a round Oz trip in a coupla years and my cruiser is the one I'm working on for it so must also be able to handle high temps like NT and so forth.

Don't want that much boost that tyres'll chirp everytime i leave the lights or a carpark.

there no point, the extremely small hole of the precombustion chamber only allows so much air to flow. If you wanted to boost it to that get a 12HT as this is direct injected and would take 15psi no worries (dunno how long the head would last though)

maybe this was the motor i was thinkin of all along, sorry dudes.

Sorry to change the subject but......

How hard would it be to fit a supercharger onto the 2H.
Dad has a 60 2H and it gooooeees a biiiiit slooooooooooooow Laughing

I said to him why not supercharge it but we are unsure if it will work.

Yeah, my flatmate reckons go the super. I just think it's not such a good idea as everyone turbos and there is easily more parts and such for a turbo setup. A super would be good in the regards that there is constant power and no lag but there just isn't the demand.

I think we should test this theory on your 60. do it. do it now.

How about i just remove the wastegate actuator line and disconnect the EDIC. Set the pump for continuous over injection and see how much power and smoke I can produce???

hmm peak power is developed from only slight overfuelling so we won't disconnect the EDIC, just wind the pump up a couple of turns. other than that, it sounds like a good plan to me.

theres a guy on her that had his 2H supercharged. do a search you might find something.

There is a complete running turbo 2H on the 4wdMonthly forum for $2500.Whack it in yours and have a spare engine as well.

Can someone please tell me what make and/or model turbo is the best suited to a 2H engine???

one of a 12HT Very Happy

Look for something off a 3litre petrol engine if you want something secondhand.

im told the turbo off 300zx's is a good match.

my turbo 2H just spat the dummy...
(due to previous owners lack of servicing and general wear and having 370 000ks when i put the turbo on...)

but i have now got a:
turbo hitachi ht18s-2s from series 4-5 rx7
turbo manifold- simple log style
3" dump pipe
oil feed (braided steel) and return line
water feed and return lines
intercooler piping and silicone joiners
intercooler 600x300

that i guess i wont be needing... PM me if your interested

there is a BOV on the pipe from the intercooler to the inlet, the bit on the crossover is where the BOV is plumbed back to. we went with a plumb-back BOV to keep it water tight. BOV only becomes necessary with the intercooler - it's not so much the boost level but the inertia of the big mass/volume of air in the cooler - without the BOV, boost was spiking to 25psi+ on gear changes - not good.

thats not the same setup dybes is talking about tho is it?>

no its not the same setup.

That is the setup that was on my 60, before i chopped it to bits.

I miss my old truck.... Crying or Very sad

So, is the hitachi ht18s-2s a low mount turbo, or a high mount?

can someone possible draw up a digram of how to set up a turbo onto a 2H? ie, from airbox, to intercooler, how the BOV should be placed into the whole set up etc etc etc.

Sorry to be such a bunny on this, but im just starting to learn about this lol

Also, if someone has a zorst manifold, i may be inerested in buyin it

I agree with all of this! I did the same on 3 different 2Hs Cool
