On a side note I hope you have plenty of gas stations around as you will be visiting them more than you think haha Great build man
Lpg vapour injection.
It's excessive but full height.

The research I did on other 20b applications applying this radiator have yielded great results plus the radiator itself is not in an outrageous price range. ;-)
Which koyo did u use, model specific?

So with this design, the three runners are pretty much equal length, which is suppose to be a good thing. Oil cooler arrived- ordered the mishimoto universal radiator, which will be here next week id say. Thinking bout stacking the oil cooler and w2a intercooler with ducting just in front of sway bar with the massive radiator north of the hood support and stacked with the AC condenser with just enough room for a large single fan.

Measuring up the boot and undercarriage for lpg tank dimensions. Trying to get as big as possible without sacrificing ALL the boot space.

Trying to get hold of one of these too. Alloy and fairly conformable

Been spending way too much time on my misses fd trying to fix her drivers door lock issues, grrrr!!
So nothing to report at mo, tho I did treat myself to some engine bay bling, took some time to track down the manufacturer of this discontinued limited edition brace, but worth it

I thought about the mishimoto radiator but it is too wide. The distance between the frame rails in the engine bay is only like 28" so good luck with trying to fit it anywhere.

I'm looking at a Griffin NASCAR radiator, has AN inlet/outlet and can fit between the frame rails. It is also 3" thick. It's a monster.

Well as it turns out, the rad DOES fit in the bay.

This thing was packaged so well!!

Just gotta decide if ill put it up front like originally planned or in the bay. I'm thinking in between the crash bar to free up the space in bay as I think it'll be hard to position the ewp. The an20 fittings are rather large.
I knew that mishimotto box would come in handy- my lpg tank test model, checking for fitment.

What the heck? Can you take a measurement of how wide it is? Maybe the specs on their website are wrong because when I measured it looked like it wouldn't fit.

Looks like a pretty tight fit too, but just the right size to fit it in there.

I'll be doing a v-mount.

I'd say there specs are based on its widest point, which is not at the top. Ill measure it in next few days. I haven't tried to get a fitting on that top hole yet either. For me it's no good there cos of ewp.

So close I can taste the lpg.
I'm wAitin on lpg tank quote at the mo.

There's been a small development- I WILL be putting this in my street car now. May as well get my money's worth, it's costing a fortune!

So last week I removed the fuel tank, engine and subframe from my st car.

So now the race is on to prep the car before the tank arrives so I can keep on schedule.

Omfg!! Beware. This may be common knowledge or common sense when fitting brand new alloy products but I didn't know.

I hand tightened the -20 to metric adaptors to the radiator and ummmm- couldn't get them out!!
I did get one out but the other is never coming out. I actually put the adaptor in the vice with the radiator still attached and tried turning the rad. No go. Unbelievable. Spent 40min trying back n forwards. I guess I shlda lubed the threads first but I was only test fitting the adaptor. It's def NOT cross threaded. It hand tightened no problem. Weird. Lesson learnt. Lube people LUBE

The attached fittings. And test fitting.

It's tight up in there but mainly due to the top fittings nut not sitting flush or parallel with chassis. I'll prob grind the one corner of the nut just a touch.
Need to fab support bars for bottom with rubber mounts.

I had my first attempt at tig welding today. Gotta say I'm a bit embarrassed by my attempts. Tho I don't think I have all the settings correct on my welder, lol so let's blame that. Grrr

Ooh man, what size/grade rod are you running, what size tungston, what gas(c25), what does your tungston look like, what amps are you running, and polarity?

If you contaminate your tungston you have to fix it. That would be my first guess of your problem. Also you should clean the metal a bit better to start with.

You should be pushing the pool with the torch that way it preheats the rod and how much gad are you running theres a lot of perosity.

That sucks man I can't believe that fitting is hanging on for dear life..... Your option may be to heat the fitting and have another go at it... Just a suggestion.. Did you get the turbo manifold straightened out?

Still trying to decide on manifold design but I do have a mate who's great with the welder so should be close to being sorted.

Hahaha, so many questions, so many variables.

Tungsten was perfect at start but I kept contaminating it. Had to grind it like 4 times.
Metal was shiny along the weld area to start but I somehow made it brown lol.
I followed some guides online regards to settings but it didn't seem to be welding very well so I kept turning amps and gas up but the truth is I'm clueless. Gonna need some YouTube tutorials.
Peak current and basic current ***** had me baffled.
I had peak set 80amp and basic at 50%
Gas started at 7lt per min but increased to 15.
Rods 1.6mm and tungsten is 2.4 I think.

Lol i know, if you contaminate the tungston then break off about 1/4" or so before regrinding to a fine point. Im pretty sure the gas was too high thats why you had the perosity.

If its just you fumbling it i can understand that. If its from the arc you should probably change the polarity.

The gas can make a big difference. Id have to loom it up but I'm pretty sure c25 is what you need for steel.

Im not sure about the peak or basic ***** but Current sounds about right 30-40 amps for thin stuff.

Are you actually using tig rod? It looks like theres some slag on the weld.
