33's under an 85 hj60

[joel HJ60]

Hey guys, blew a cv joint or axle today at sugerloaf so maybe my question won't be relevent until I get more cash, but how much lift will I need to fit 33x12.5x15 under my stock '85 HJ60??

And is extractord, and 2 1/2" exhaust the way to go for a bit more power. And how much has it cost everyone else?

No Lift!!!!!!!...well unless maybe if your springs are well sagged. Im running 33" MTR's and they only just rub on the inner part of the rear arches on full compression

I put some custom 2inch extended shackles and reset the springs, and mine fit well. Just got to watch that the rear guards don't cut into the lugs on the top outside edge of the tyres when going over those washout humps etc.

The front ones might scrub a litle on the front edge of the gaurds too.... a couple of good hits with a lump hammer and block of wood will fix that... mine only had to be hit in about 5-10mm to clear.

Hope that helps.

Oh, and you'll need 15x8 inch rims... incase you needed to know that too.

You will need about 2 inches of lift to fit 33's comfortably.

You can do this by having your old springs reset ($60 per spring roughly), buying a set of 2 inch lifted springs ($1000 for whole kit) or getting a 2 inch body lift (about $250).

Extractors and new exhaust will get you a bit more top end power, but the way to go if you have the cash is turbo.

I have an 85 HJ60 with aftermarket turbo and have spent about 4k all up on getting turbo and front mount intercooler fitted and i run 35's with no effort.

I take it that you run hardened pistons, and have re-built the motor?

The many people I have spoken to said that turbo charging a 2H is the fastest way to kill it, and the 12H-T is the way to go if you can find a decent one.

No, i havent rebuilt the donk. It is running standard pistons. Its been turboed for 18 months. Hasn't missed a beat. Got the big end bearings changed last week as a precaution. Doesn't use oil between 5000km services, and doesn't use coolant either.

The secret for setting up the turbo properly is setting the right fuel mixtures. Sure, you can overfuel them to the buggery, and you WILL melt pistons, but get a lot of power before doing so.

Intercooler also plays a big part. Cooling the inlet air helps reduce some of the thermal stress on the motor, and also increases HP. I am currently running 12-13psi of boost (which is heaps), but have a large front mount intercooler which reduces the inlet air temperature pretty much back to ambient air temps.

The temperature gauge sits just on a quarter the whole time except when you are flogging it. Highest I have seen it get is just over half way.

Exhaust temps haven't gone over 480 degrees, which suggest we could give it more fuel if we like. But seeing as though i am happy with its performance and reliability, I'll leave it as is. Piston skirt cooling would also be great.

A 12h-t is definately the way to go if you have the money. But a good one will set you back probably 7k or so. For that money, i could destroy 2 2h's and still have change.

Serious, I'd say they could fit under my current stock setup, but the second it went off road they'd rub to buggery.

Carts could you send me some pics of your rig and specs. PM if you want. Thanks JOEL

With my 2" OME springs 33x12.5's still rub on the edge of the guard i reckon by about 15 mil when flexing.

I had some 33x10.5 jt2's on they fit perfectly and do not rub at full lock at all, and they are really about 34"

This post from shadow is interesting where he mentions the size of a 7.50R16LT traction tyre to be 31.96".. so 32" standard its not very hard to turn a 33 my stock 2h had no issues.

I was after 33's but was not keen on 10.5" I went 32x11.5 mtr's.. they are sweet.. i'd guess that an additional 1" body lift would see the 12.5's fit like a natural.
