Hey guys,

I'm just wondering if you guys could help me out here.

I have been offered an R33 GTR LM from Japan and the seller has sent me a few pictures of the underbody.

They are a few surface rust patches on the underside and the compliance place said it may or may not need to be sand blasted + sealed + painted.

But he wasnt happy that on some of the factory underseal it has blue paint,

My question is are all factory underseal supposed to be black only or it colour coded to the body colour ?

I have attached a few pictures so you guys can have a look at it

Many thanks guys

Ronny T

Look the snow tyres on it. Snow country vehicles are never a good buy. Surface rust today, swiss cheese in 10 years.

Unless of course you decide to spend thousands disassembling the car after purchase and de-contaminating/rust proofing every single surface.

Have family that live in Osaka and while it snows there its never heavy enough or frequent enough to warrant snow/winter tyres. They make do with all-seasons.

If you are or know an expert with paint n panels, go for it. The LM is worth it for the colour alone IMO

Better question, how long are you planning to keep the car for?

SAU can recommend a few reputable dealers with which to dispose of the vehicle once you've had your jollies ;)

that is surface rust, and by the looks its also factory underbody guard. i had the underbody sandblasted on my car and it is the biggest bullshit pain in the arse job its a very big job, newer cars have alot better rust protection than the ones from the 50s and 70s

this car needs a good steam clean and scrub and to go from there.

Id be asking for plenty of detailed pics of the strut towers, which can and do rust frequently on 33s and 34s, and would make it not compliable, even on cars with 'good' auction grades. The stuff underneath is as mentioned fairly normal, and to me, a sign that it hasn't been hidden under a fresh coat of under body blackjack ie what you see it what you get. Would check the seams underneath are ok too, that's where the rust forms in areas of trapped moisture.

The 3rd picture looks like its bent underneath where the factory jack goes. It also looks like the circles there are from a hoist with the rubber feet have pushed up into the floor

Doubt it. The rubber on hoist arms do a pretty good job of keeping things square. I and none of my other friends have had a problem. If it was bent previously then you used a hoist it may bend the pinch, but they usually have a 10-15cm radius.

I'd say if you can still see the over spray underneath, it's been well looked after.

They rubbers probably do but when you put them where the floor is it bends the floor up and leaves those circles you can see in the 3rd picture. My car dosen't have those circles and neither do others I have looked at. Obviously none of you and your friends are that silly to raise a car up by the floor

    • Update for the sake of closure   Ended up getting the intercooler piping all sorted, new plugs and yellow jacket coils, and she was idling mint until it warmed up while I was bleeding the cooling system. Found the misfire to be localised to cyl 3 by unplugging coilpacks, ran a compression test, that checked out, then decided to get a mate to check if that spark plug was firing out of the motor. Upon cranking it over, with the injectors disconnected, the car actually fired and ran on a couple cylinders and heaps of fuel came out the top of cyl 3 I'd say that injector's either spraying incorrectly or spraying far too much, which is fine as I'm planning on replacing them anyway I'm planning on making about 250kW on flex fuel, and have a set of 1000cc injectors from ozautosport, obviously overkill but I'm planning on building the motor and running more boost further down the line, do you reckon they'd be too big for a smooth idle on 98? Thanks for the replies gents, much appreciated
    • I'm confused. You said you want to "remove the clear coat from most panels" but it sounds like you are actually doing a full respray? Few random things to add -  If you chase the blistered paint with 120 grit, I can almost guarantee you'll chase it down to bare metal (that's fine). But if you paint the car from here, you'll have nice little indents where ever the blistered paint was. The new paint won't magically level out the low areas, you need to fill them. Which leads me to the main point I wanted to add, make sure the whole car is flat before you paint it. All those areas with blistered paint you sanded out, make sure to fill them and triple check they are flat with a block guide coat. I'd also check the whole car is flat with a large block and guide coat but yeah up to you if you want to go that far.   
    • 300hp (225kw) is barely outside the standard turbo's range with a bit of extra boost in it (200ish). If you are going to change the turbo you should aim for 250-300kw (330-400hp) to make the expense worthwhile
    • A couple of things, firstly omg that turbo is expensive! $3,000 USD for dinosaur technology is robbery. You could buy a G series turbo and have a good amount of change instead.  If you want a good budget option, have a look here - https://hypergearturbos.com/product/rb25dethighflow/ If you are keen to spend more, have look at the modern turbos, Garrett G series, Borgwarner EFR, etc. Have a look at the RB25 dyno results thread for inspiration.  If you upgrade your turbo to something that will support the 300hp you want and only "probably" have Haltech ECU, your car will only "probably" run. Actually, no it won't run. You are going to need the ECU and injectors at the time you do the turbo upgrade.  No thoughts on "this much boost" as you didn't say how much boost that actually is. Having said that, plenty of unopened RB25's making even more power then what you are chasing.
