4BD1 LR 120 Turbo?

Thanks JC. I will sort the surge problem for now and see how it goes. Unfortunately I have to keep it fairly bullet proof as will be the main work truck here other than a Toyo HJ75, HJ45 and Hj47. Land Rover S111 X2 and S11a X2 . Obviously the 120 will leave the others behind;) So is earmarked as No 1:eek:. Better off road, Better on fuel and more load space etc. I just want it for a TOY:(. But has to go to work.:( Dont worry I will have it 90% of the time:). I just hate having other people using my truck in the bush:( Be good if it could be governed back for low range work while its out of my sight. May be a few zippy ties on cable:twisted:
I will sure fit pyro and boost gauges. Not sure how yet as dash is booked out with Volt, Aux Fuel Clock etc. I dont want pods on dash. Spoil it:(
Sure will look you up if I need any thing to sort this one. Thanks Tony

That sleeve nut on the wastegate rod (in pic 3) is used to adjust the boost.

Get thee some gauges (boost and pyro) to see what's happening.

Well seen Dougal,

I must be blind:o. Mine is a solid rod, and is set to 7.5psi. I didn't even look properly at the pic obviously:(

Shortening the rod will give you more boost, but fuel will have to be adjusted aswell.

As Dougal says, gauges, gauges, gauges!

Just a tip with that banjo fitting under the injector pump. If you find it really close to the engine mount, check the mount is not broken over on the engine. Even made a special spanner before i looked there in my case. D'oh.

Do you think the exhaust pressure is blowing your wastegate open?
I cut the rod on mine and welded in a nice adjustable threaded section. With the wastegate adjusted up to give 20psi boost it's got a hell of a lot of preload on it, spring can't have much travel left.:D

If the bracket bolts to the back of the compressor, you can just use a stack of washers and longer bolts to get more boost.

Looks like I'm up for Boast and Pyro again:( I'll get VDO they dear but good.
Not sure how to fit them yet as has to be out of harms way.
Workers that chuck things at the dash:mad:.
See how it goes with a tune before looking into intercooler. I put an intercooler on my 4D56T mitsu (Have Pics) and made more improvement than the Turbo its self. I put a spacer under waste gate on it as well then played with fuel. The 4D56 made a heap of power but got to hot on Phyro. 850deg after the Turbo. It didn't last long. Now runs 650 on the dump pipe. Would be a lot warmer pre Turbo:eek:.
As advised I will try to fit phyro pre turbo on the Isuzu. I just don't want it to blow head gaskets o, Drop valves or kill Turbos etc. Will order boast and phyro tomorrow so we can try to tune it. Thanks Tony

I'm afraid so:( May be I need another Yota:angel:. I purchased it for a farm hack :eek: This 120 is to nice to trash:( . Has a few minor isues but now have realized I'd like it for my self.:) I'm fitting some armour to it to it shortly. Diff guards,Stearing guards etc. May be a hidden camera:angel: Tony

Done the fuel system over today. Got the fuel suply to lift pump banjo out and no screen filter:mad::mad:. So pulled all lines off and blew out. All new filters. It still surges at 2800 rpm:(. On road test on hill can lug well up to 2200 rpm then not so good. Under light load will get to 2800 and surge. If reved with no load hits govenor at 3400rpm and runs clean.:confused:. What is going on here? Pressurized lines and can't find any leaks. Got me buggered:( Tony

I may have to fit the phyro post turbo:( As I'm not prepared tp pull the manifold off to drill it. If I get it close to the turbo should be ok?. Just have to allow for temp drop when tuning.

I've changed the exhast a bit. Only 2 1/2" though. :( IT has made a huge improvement in mid rev range and has a huge turbo whistle even at idle:angel:.

Have any of you got pics of pyro and boost fitments? Thanks Tony.
