Default SC36 TD04 Swap?

Hi all,
Quick noob question. Will an SC36 billet turbo from a Bug bolt straight onto a Hawk WRK TD04 out of interest?

Thanks,

Max

Yes. But will need a remap. What supporting mods are you also planning?

Sorry about this I know it’s an old thread. A guy is selling a refurbed sc36 and I wanna swap it out for my td04 on my 08. What effect would this have on the internals when fitting this ? would it be okay to fit an sc36 and map it to 300bhp without any issues ?.

cheers

If your target is only 300 then buy a turbo rated to 300bhp

Billet your td04 or stick a vf 35 on there

Although you will have room for improvement with the sc36 as at 300 your not seeing its full potential

My target is 330/340.
I was thinking about billeting my td04 actually.I know that I can’t reach anything over 350 because of the gear box unless i fit blast plates to the box.I am ideal world it needs to be forged but it’s running nice at the moment with the map I had put on their last year.

Blast plates are a joke and a waste of time and money

Be as well wrapping your box in cling film as the case flex myth is B.S

You would need an uprated gear set to strengthen it

I doubt you would see much over 300 on TD04

VF35 would be your cheapest and most responsive as well as that SC36 would be fine there too just depends on costs.

I’ve heard conflicting reports in regards to blast plates myself. Na, the td04 is constricted on what they can make unless they have been billet’d. My current td04 made 283 with a map which I was pleased about. I’m assuming the sc36 would only fit with an sti intercooler ?.I did think about a vf35. Rm performance also modify a vf38 by using the flange on a td04 and placing it on the vf48 but want nearly £1600 which also includes returning the turbo, fitting, mapping it in and also an oil change. Ideally I’d want a cheaper option than that.

It's not hard to understand why it's nonsense



A VF35 would only be around £300

Sell your TD04 on Glanza page and cost will be reduced a little more,

Plus I can billet the vf35 if I wanted to do that. Good for 325 aren’t they the vf35 ?.That’s interesting reading, and if it’s come from Andy Forrest it makes me happy. How much would updated gears cost ?

Not cheap, could replace a few boxes before you get to gearset costs

Tbh unless you plan on chasing 400+ i would stay 5 speed, and throw a box at it if it went.

I read that the later ones from the 2.5 are a little stronger

Yep Vf35 can also be billet if you want more in future as well.

Good few folk have managed to survive on 5 speeds below 400 so should take all the vf35 can puff out at least with some sympathy shown.

Once again you need to acquaint yourself with the differences that the 2008 onwards Hatch WRX has with other Imprezas and the WRX STI Hatch.

Your TD04 looks like this with a bolted compressor exit flange to suit the Hatch WRX intercooler


A current SC36 looks like this with a sleeve type compressor outlet which would require the ditching of your Mishimoto WRX intercooler for an STi style one and all that that entails.



You could go for a Blouch GT 380XT as it's made to suit the Legacy and WRX fitment

I would want the Sti intercooler if it were mine anyway.

When I spoke to the guy who’s selling the sc36 he said to me that it would fit but looking at the pics I didn’t see any flange on it that was similiar to the one on my td04, which is why I asked the question on here. If I had a process West intercooler it would be problem solved.

Speak to Scoobyclinic - their turbos are blouch derivatives so maybe they could source you one to suit.

Don, you beat me to it! Was just going to point out the SC36 wouldn't fit, or a standard VF35 for that matter either without a change of housing! LOL

Get the Sti I/C on there then your not limited to what you can fit,

Be much easier to get hold of turbos as well i bet.

Could do the full vf35/TD05 swap with I/C for price of a new Blouch £££

Looks like a vf48 conversion from rmperformance or the one that don pointed out is the direction I’d be going to when I come to doing it 😂

There are other things to take into consideration which would dramatically increase the cost.

With those blouch turbos not a kick off £1500

Im pretty sure there would be enough in the budget to cover it,

Other than the actual cooler what are the major costs involved ?

Some pipes ?

Scoop % Undertray ?

Or is the swap not as simple as on newage ?

The reason I bought my wrx is because I wanted to see it develop into where I want it to be. It put me off reading about the sti piston and ring land problems involved with the hatch sti’s, not saying mines bullet proof in anyway but I read all the problems being associated with an sti hatch. With the wrx having different piston compressions etc. if I was too sell up, in which I’mSure I would in the future I’d go down the jdm hatch route definitely.

Like I said mate. Rmperformance do a vf48 conversion involving the td04 which involves taking the flange off my td04 and placing it onto a vf48, which includes a full refurb of the vf48, fitment, map and oil change for £1600, which considering isn’t a bad price. I can understand why people say buy an sti though.

£1600 tho

For essentially a vf48

Why would you not want the Sti Hardware ?

Surely the I/C is better to begin with,

It also does away with the hassle you have now trying to find upgraded turbos that mate up.

Folk say buy an sti because the price of forging it to make reliable after ringland go would prob be less than cost of your vf48 upgrade plus a gear set,

If you're doing it then you may want to consider:


Uprated turbo
Fitting


Plus......
STI TMIC
STI TMIC brackets
STI scoop
STI scoop under tray
Better exhaust
Decat or sports cat downpipe
3 port boost solenoid
Uprated fuel pump like Walbro 255 or SWRD
Uprated panel filter
remap.


Recon there are £1-2k in additional parts there on top of the turbo price depending on what you go for.

I’ve already got the exhaust, mishimoto tmic, sports cat, 3 port, fuel pump, panel filter and a remap. It’s the turbo holding me back mate.

I absolutely see where you coming from bud!. If I was to replace mine I’d only want another hatch, I love them. price of a hatch though compared to a blob or bugeye are quite different. Saying that hurst sell a lovely forged 330’s for £16,000 but I’d like a jdm but they are from £16k onwards. If I had the money I would.

True.


You're a little screwed on turbo choice unless you change to STI TMIC or FMIC then Matty.


Either spend a fortune on a bespoke turbo for the WRX setup or sell your TMIC on and but something that suits the VF48 STI turbo. Would be a lot cheaper in the long run.
