yep, the 2 orders are in and just waiting for shipping.
2 1/2" lift complete with caster bushings and shocks, $790 OZ. i was going with the JDM kit but the cost was too much for my budget.
Dobson kit.
i will give them a try and if i am happy then i will be offering the kits. or you can order your kit through Slee off road, West Coast Cruisers, Spector.
shipping is the killer...

Will you be selling the kits yerself Wayne, I would much rather just get it from you pay the little extra to not have to deal with duty etc.
sorry to walk into your conversation fellas but i got two questions for you 1. would wrapping your exhaust manifold and where your exhaust drops out lower engine temp(decreasing convection to the engine head because i think you are trying to avoid a cracked head) 2.i saw a program on t.v. where instead of using the wastegate diaphram to dump exhaust around the turbo they used it to recycle the compressed air back into the air intake before the turbo, in order to limit boost psi and turbo speed but still keep the turbo spooled up(i.e. carrying over boost while switching gears). so the question is, are you worried about just the boost to the engine or also about spool speed.

I'm not a expert .. but betweem shift you have vaccum in your engine, so it means turbo lag .. vented ir in the intake again reduce it, in order to keep the turbo spooling at same ( or like it ) speed.
this help .. ?

Why not start a new thread? I'm sure it would be an interesting topic, worthy of its own thread.
Hi there
My name is Bong.
Your mods on your LJ78 2L\TE are quite interesting and the best part about it is that you're happy about the results. GOOD JOB!
I bought an LJ78 in 2003 used and have had similar experiences with the blown cylinder head gasket, cracked cylinder head and very hot temperatures even on a slight climb. I'm not going to bore you with the history of finding a fix since you're already familiar with it, so I'll go straight to my version.
I'm not really equipped with a whole lot of equipment so I oicked up a couple of used 1 ft by 1 1/2 foot 2-inch inlet and outlet pipe radiators, bent some 2-inch stainless steel pipes connected them with hoses and front mounted the contraption(dual intercooler) slightly below the airflow to the radiator. I'm not equipped with a pyro so I have no idea of what the exact exhaust temp is. Anyway, I road tested the vehicle today by going up and down a 15deg slope for a whole hour. My engine temp maintained at operating temp and never went at or above the halfway mark which was what normally happened before the mod. I thought I hit the lottery with the results of my mod until I read your mod results tonight. Now, I wish I knew how to get a 14 PSI boost increase. Any help you can extend would be much appreciated.
Cheers

My personal opinion is that the engine temperature gauge is a very poor choice to monitor what is happening in terms of heat in the cylinders and turbo. I have had two Land Cruiser engines with boost gauges and pyrometers installed, a 13B-T and now a 12H-T, and with both engines, the engine temp gauge has not moved despite pushing the engines to high EGT's. IMO by the time you see that needle creep up, it may be too late to prevent damage.
An ISSPRO pyrometer costs less than $200, and is certainly much easier to install than a fancy dual intercooler. I would have placed a pyrometer and boost gauge much higher up on my priority list than that...especially now that you're considering bumping up your boost to 14 psi on a 2LT-E?
Then again, there's a good chance you have much deeper pockets and a lot more time on your hands than I do.

Hi all... recently picked up a 3600 psi cng tank / system for my LJ78.. after exhaust & intercooler I will be engineering & installing this system. Looking also to control by boost pressure.. but will be installing a stepper type of flow control valve..

I think I mentioned this to you before, but will again as I looked up the specs. I run methanol/water injection. When I run more than 50/50 meth water in summer, the methanol auto ignites BEFORE TOP DEAD CENTRE of the piston travel. This is very hard on the engine and can ultimately result in broken pistons etc. It's clearly audible as pinging/knocking. I looked up the auto ignition temperature of CNG and Methanol to see if it would affect you also. CNG auto ignites at 540C and Methanol auto ignites at 470C. So I'm thinking you'll have a similar problem to what I have. Why does this auto ignition happen? Basically 21:1 compression ratio, plus boost, plus high intake temperatures results in very hot air at near TDC. Also, the precombustion chamber and glow plug stay very hot even after the combustion process.
I think your CNG system will potentially be pretty neat, but it's worth considering this auto-ignition (pre-ignition) problem carefully. Has CNG been adapted successfully to similar indirect injection turbo diesel engines?
BTW, interesting thread bump. I don't think I've read this thread before, and I have done a lot of reading on 2LTE stuff....
GTSSportCoupe... you are correct.. the system will need to be properly engineered/designed & debottlenecked... I'm looking to incorporate PLX controls & sensors.. they make a nice bluetooth package with no physical gauges.. all gauges are displayed on your phone... techy silicone valley stuff...

Then will run all thru a new ecu.. which will control denso+cng... but I have a lot of engineering stuff to figure out..

Right on! Would love to know what aftermarket ECU you're looking at. I wish I could customize the fuel/timing maps for my engine....
