Hi All, Bolted up the head today using the 1/2 arp studs (ford cleveland) and the factory type mls gasket.I enlarged the gasket hole with a stepped type bit. Eric's comment about crap getting between the layers is true ,but the lexus gasket is not crimped around the cylinder and only in...

Thanks its good to know that this is a std thing to have to do.

Bottom end is off being balanced,but will be putting it all together in the next few weeks and wll post a few pics. Darren

Not to smart, I to have spent way to much on a Supra as well.

Anybody else had the problem of not being able to fit the cam drive gear over the new camshaft without machining a piece out to clear the lobe.

Us Aussies are pretty smart bastards.

I have a milling machine in my workshop. After much asking I have MLS 1uzfe factory headgaskets. If you try to use the wrong tools for enlarging the holes you will have problems.

The holes in the std MLS lexus gasket is just over 12mm std,so it only requires a small amount of dremel/die grinder work on the gaskets. My heads and block are done .A friend of my has his 1uz now running with the 1/2' studs and the mls gaskets and is happy with how it all went together.(He...

I have gone to 1/2 arp studs $260 AUD makes for a much better deal than $750 USD . Yes there is a couple of hours work to drill and tap the heads and block,but I feel it is a much better job than Cowbobs set-up of L19s . Darren,

After reading through this and the last thread I think we will just disagree. Eric will use 10mm L19 @ 100lb and I will use 12mm studs @95 lb (in a alloy block). Good Luck

A mate of mine is have head gasket problems with his 1uz in a mq patrol.He is running twin gt28 making 580 rwhp.I have just lent him a set of mls late model gaskets and he is going to studs as well.I have had headgaskets blow on the 2jzgte (hks & arp studs). So I am thinking for an hour or so...

12mm or 1/2" appears to be a good up-grade after reading that thread. Problem being the drilling and tapping is the easy ,just that ARP have no listing on replacing the 110mm bolt with a 12mm / 1/2" stud or bolt.I supose a 12.9 grade cap head bolt would do the job (unbrako or similar). Darren .

Anyone have any ideas on part No. for some 12mm head studs for a 1uzfe,as I will be running high boost and would like to go to 12mm over the std 10mm. Darren

How did you go with the sm4 set-up. Darren

It two would have had bad compressor surge as well ,I have also driven a supra with twin 3540's .so what is your point?????????

I think he means 2.5" to feed the turbos.

2 x Gt3540 60lb = 120lb compressor flow. Have run 2x gt3040 on a 2jzgte . check the maps.

I would think that twin gt35 would give you a major compressor surge problems .

I removed the filter mount and made up a 12 mm alloy plate to match ,drilled and tapped two 3/8bsp to -8 fittings this morning.I will then run an external filter mount and cooler.Trying to open up as much area as I can for the turbo pipe work.
