Oh shit that's not good

[luvpsi]

Sorry mind my language

[ARTZ]

Damn I'm going to be running this setup on my 25 and I have a 3" looks like I'm upgrading to a 3.5"

or just run a screamer

[Bsa]

In just pulling the head off going to need a gasket one day and if it's more then a gasket a 25 will be on the cards

[luvpsi]

or just run a screamer

That's what I plan on doing

[STATUS]

We went till 12:45am Dave. But then we had to send him to fix it up. His screamer was basically aimed at me so was too loud and couldnt hear what i needed to hear.

Finish it off this week hopefully.

Might have to change my name to midnight tuning

get some decent knock ears, or are you running some already?

impossible to tune without them, you cant hear det audibly till way to late and headgaskets are gonna blow left right and centre.

So 25 seems to be happening head bolts are striped where already a bit damaged and they are way over torque spec. Unless anyone knows how to remove a striped headbolt. The bolts under the cam coveres where 10mm Allen key then the 3 in the centre section are just under 12mm Allen key head so I'm thinking it's been tampered with once apon a time in jap land or is this normal on a 20 as iv never done one before?

[Bsa]

Got it dont worry haha

[BOOZTJUNKEY]

Just ear muffs with hose we used work great can hear everything. I'm looking at going that way money is what's holding me back. Just got the head off. Bottom end is stock but head is warped needs a quick skim. Might be worth just getting a 25 as a decent gasket is 450 then need to have the head machined then new head bolts. So that's near 1000 I'm guessing. I can buy a 25 for that and use all my 20 stuff seems to be the smarter option. Not to keen on buying a new 20 tho it would be cheaper

[BOOZTJUNKEY]

Yeah but what ever engine you buy may have underlying problems :-(

I have a spare engine here preety sure it had bent valve ur more than welcome to take it as parts

[Bsa]

What engine is it?

[BOOZTJUNKEY]

It's a rb20det

I have kmon ears. But i prefer to have my head over the engine. I know its risky but i havent mastered the kmon to my liking yet.

I have never missed a ping yet. Just that some people want to push limits (BSA).

[Bsa]

If you do it then do it properly I asked him to push it my fault

How in the hell did you warp a head though? The motor must have been cooked at one point or another. I had a session where a lower hose came off my radiator and the coolant temp sensor was reading air temp whilst the car was at speed around Calder. As soon as I backed off and started my cool down lap the coolant temps shot up over 110deg C at which point I had no option but to shut it down hot. Got to the pits , fixed the hose and started filling it with hot tap water and started engine to circulate. 20,000kms the engine is still ok....so it must take a bit to warp a head!

Provided the base engine doesnt have issues you can push a 20 pretty hard on the dyno. We pull safe 275rwkws, cant get it to keep pulling higher numbers with more ignition when all the temps get up high like they would on the track

[Bsa]

It's never over heated while I have owned maybe previous owner cooked it all in all its going to require money. I would rather make 270 kw easy rather then stress the motor to get it

You can pick up a half cut r33 for about 5k or less
