GTO (3000GT) manifolds + turbos on 8G VR4?

[Gly]

any one tried this or even compared manifolds for fitment

got a bit bored, so started googling parts,

the VR4 and GTO manifold gaskets look very similar to me....

legnum vr4 gasket HERE (http://www.japaneazicarparts.co.uk/proddetail.asp?prod=Legnum%2FEx%2Fman%2FgasMR21227 4%2DMR281718%2DMR281720&cat=16)

3000GT VR4 Gasket HERE (http://www2.partstrain.com/products/Engine/Exhaust/Exhaust_Manifold_Gasket_Set/1991~MITSUBISHI~3000GT~6~3.0~3000-GT4WD-001.html?index=1)

could make it easier for those looking for big turbo upgrades?

[bradc]

worth a shot, could probably find some 6G7x series manifolds fairly cheaply. I would imagine that all the models from 2.5l to 3.8l would share the same cylinder spacing?

[zedy1]

hole spacing is different so wont bolt on straight

[Eurospec]

Correct. It wont go.

The turbos wouldnt be bad if you could get them on though.

Cheers,

Ben.

[Gly]

is it even close?
could the holes be redrilled to fit?

[bradc]

Are they completely totally wrong, or just a wee bit wrong?

[Kieran]

Correct. It wont go.

Ben -

Do the GTO turbos flow much more than the little TD-03s we've got already?

General consensus (though I must admit this is NOT backed up by flow maps) is that the JDM turbos (TD04-9b) don't offer much above our TD-03s, though as I say, this is conjecture and not proven, as far as I know.

I imagine the UK-Spec turbos (13's aren't they?) are a better bet?

[Gowf]

The UK 3000GT's came with 13G's. The 9b record is 440bhp out of a 3l lump, with the 13g's being in the high 400's. It is now being thought that the 3000GT actualy comes with 11g's as people who have been taking them apart are finding that they are not true 13's.

Should have some interesting results for you soon though....

[bradc]

my car isn't much behind the 9b's then, and considering how much effort it would be to fit 9b's, I doubt it would be worth it. Plus they won't spool as low in the rpm range as mine.

Some large TD04's are probably the go then, or some TD05's

Just out of curiousity... what do you recon twin TD05 20G's will make then?:thinking: :afro:

Errr.... A 6A13 that sings 'Please release me, let me go'?!?! :speechles

[bradc]

I'd say 750-800hp. There are lots of EVO's out there with 400hp on the stock turbo.

I assume this is what you're fitting to your car?

Just to answer some of the questions:-

The GTO Manifolds are not even remotely close- miles and miles out. The block is much wider.

The TD04's can be made to fit onto the stock 03 manifolds, but the front becomes tricky for space vs the engine mount (you have to cut it) and the oil filter housing. Dont underestimate it though, its a lot of work.

Much easier would be to use Scooby turbos, the fitment is much much easier and you can get them on with a little drilling.

Cheers,

Ben.

Which scooby turbos would that be?

[Eurospec]

Which scooby turbos would that be?

Sorry- i might have made this sound too easy. Its not just like you drill a hole, bolt it on and go. Its simply that the scooby exhaust flange is much bigger than the mitsu one, allowing you to get the scooby tub onto the galant manifold much more easily.

You still have the physical space issues, the turbo clocking issues, oil drain and feed etc.

I would think a set of 13T's (Std TD04 tubby from a scoob) would go on, but the housings are bigger. The compressor housing at the front may well be an issue vs the engine mount. These will flow a lot. Very similar turbos have been shown to make over 500bhp.

Ben.

The engine mount isnt really the issue, its the oil filter housing... if you mess about with the 13g's you can get them to fit on to the stock manifolds (rear is not too bad) but if you mount the front one on the manifold it becomes hard up against the block, so you idealy need a filter relocation kit and to extend your manifold by 1 1/2" and then you start having fan issues along with the engine mount.

The 13T's as Valmes has posted in the past will indeed go on to the standard manifolds with modification, but you still then have the oil filter, engine mount and fan issues issues. The rear will be fine as long as you dont have a compressor housing thats any bigger than a 13G, otherwise i do believe that your into bulkhead modifications

[Eurospec]

....... believe that your into bulkhead modifications

FBH Mod!! Or cut the bulkhead like Marks!

Well this is true. No need for a heater then or a passenger as you can have quite the conversation with your turbo.
