Gud man Martyn, an easy solution make sure to try a 35 aswell on the same car so we can compare

The Gaffer

Hi,

thats the whole ethos behind the 33 Billet, spool of a GT30, power of a non billet GT35.

Martyn, one on its way for testing.

cheers

Good man, happy to be of service !

Ok, im going to have to ask this as tbh i am not the best at reading dyno print outs.

Kev, you said that the GT33 billet will spool like a Gt30... is that A gt30 billet?
And on a 2.35 with sti5 heads and standard cams, wgat sort of spool would i have on both?
From what you have said, why are people buying the 30 and not the 33?

MartynJ

The way I interpret it Ken is that it will spool like a stock GT30 but perform like a stock 35R. Could be the perfect combination for those with the smaller capacity engines, but I would put a Billet 35 on yours and not look back.

I wouldnt be pushing the 35 to near its potential, think it was yourself Martyn that said with the standard cams, they would limit me, to maybe 530 to 550 with a drop of meth.
I would be very happy with 500, of course all the better if i can get up to the 550 mark without having to change anything else.
Reason i thought of Gt33 was that i allowed because of say my 550 cap, the turbo wouldnt be running its max, and i would be more sure to get good power, Fuel here in Ireland is a bit of a disaster, and of course if i could make good power without using meth, well all the better.
Would the gt35 Billet be much more laggier than the GT30 billet?

The Gaffer

Hi,

the GT33 BILLET should spool as good as a stock GT30 non billet, and give the power of a GT35 non billet, thats the theory at least.

For a punchy, quick spooling car the 30 Billet seems un beatable which is why we have not tried the GT33 Billet, it may be a belter but as of yet customers have opted for the 30 or 35 billets as they are proven by now, both being fitted to our Time attack car, time restraints stopped us trying the 33 Billet.

We were still mapping one of the 6 cars entered in the Birket relay endurance race at 11.30 PM last night, this car is on a 35 Billet, time restraints if you see what I mean.

Looking forward to see the results of the billet GT33.
Would you think the turbo will be any good on a forged EJ22 and STI V6 heads?
Or will the heads be on their limit then?

Maybe a S206 is for sale soon?!

MartynJ

Saw near as dammit 560bhp from my mildly ported version 5 heads and cams on the S206 albeit on race fuel (20% meth yielded 531bhp and a 10.889 1/4 mile), so as a basis for the 33 Billet your heads should be ok to start with.

I think I have to get E85 until Simon comes again to Austria for mapping in Spring!
I need the 10s on the dragstrip!!!!

Hi,

for those interested yesterday (Sat) was the Birket 6 hour relay race at silverstone.

We had 6 cars entered all sporting Billet turbo,s.

Many drivers in the pits recognised some of our race drivers greeting them with comments like, "6 hours racing in a Subaru, you must be joking" we were not joking at all, we won our class and got a 7th overall out of 61 teams entered.

Some teams were made up of Le-Mans cars, radiclals , purpose built kit cars with bike engines and of course Caterhams etc. etc. some serious machinery was out there, all in all a fantastic result for the cars and their pilots.

Lets also not forget the team supporting the vehicles including mechanics, tackle passers and photographers, pics to follow.

Cheers
Kev

top results lads.... Congrates on proving them wrong mate

The Gaffer

Hi,

thankyou.

The best bit was to shut up the disbelievers, especially the ones with purpose built race cars costing 3 and 4 times what our cars have cost, in fact two cars in the team run standard STI 8 engines with Syvecs ecu's and SC36 Billets.

Its now shown the big boys that the Subaru's are here to stay, get ready next season.

Great to ***** the pomposity of 'car snobbery'.

Except it's more than merely pricked - you've positively sledgehammered 'em!

Excellent stuff.

GT33 Billet received, just need to build the 2.1 stroker engine to put it on now, lol.

Many thanks Kev !

Hi Kev

Continuing to enjoy this thread as ever.

Just like to add our congratulations on your great achievement

Hope you get your just rewards for all your hard work, with more new business.

Maybe there'll be a traffic jam on the Farm road soon!

Hope Adam is up to speed on his traffic management skills.

Well done Kevin and drivers.
If my car was ready for a turbo i would have gladly sent her over to be a test mule.
I wonder will the billet 33 spool much later than the billet 30.

For some strange reason i have a feeling that the GT33 Billet could well be an over looked gem of a turbo,
am i being unrealistic to maybe think it may well spool same as GT30 Billet, but have benefit of the higher power??? And could be the turbo to go for

The Gaffer

Hi,

sometimes a combination of turbo with fmic, inlet manifold, headers etc works and sometimes it doesnt, take for example my car, 2.35 non avics, DH22 profile cams and an SC54 billet direct fit turbo, stunning ! great figures and on the road a complete animal, same bottom end but with avics and some wild cams, SC54, fitted to a hawkeye, spool was poor and power was a struggle, swap it for an SC46 Billet and its stunning, why ?

Its a case of different combinations of parts, some work and some dont.

We do now have a growing portfolio of combinations that do work, at least with all the testing and racing this year we can advise the correct choice of parts, matched to the correct turbo.

Quite often we can save people a lot of money on completely unnecessary parts.

We will put the 33 billet through its paces as soon as we can, in fact a poster on this thread dropped his 2.35 hawkeye in fo a GT30 billet..... mmm...

Cheers

Nice photos above Kev and the team. An exceptional result and isn't it sweet when things come together especially when doubting Thomas's have to take note. Not only a great result for you but a great result for Subaru marque too.

MartynJ

And never mind the fact that even the same combination of parts can produce different figures on different cars, lol.

Hey Kev,

I've been following this thread and the litchfield one for awhile, since pretty much nobody in the US have run these turbos yet it's hard to make a decision. But I've been seeing some great numbers/curves so far..... just hard to decide when some are running E85 (I will) and others VPower (I assume it's like 100 here).

Do any of you have experience with both the litchfield LM450 compared to the SC46 twinscroll? Trying to decide between the two, from what I've seen they are pretty similar apart from the SC46 costing a lot less.

BTW I'm running a full JDM STi twinscroll engine/drivetrain. And since your on the topic of "what works" I was going to run this by you. I had my VF37 reworked to be a PE1825..... which ended up working like crap.

Here is the dyno on 93octane, hot day. As you can see the spool is horrible due to the turbo.


Now my plan is to run the following, with the goal being response and good power (350-400whp).

SC46 or LM450-S60
Process West TMIC with splitter
ID'1000's (for E85)
APS inlet
APS 70mm CAI
Port/polish throttle body
Cooling mods (turbo blanket/titanium heat shield/DEI gold tape and wraps)
It currently has a Hayward & Scott downpipe matched to MRT exhaust
3 port solenoid in a hybrid setup with MBC (to keep it from exceeding the ECU boost numbers)

Any tips you could offer, things to ditch or things to get? Any help would be greatly appreciated. And while the SC46 is cheaper.... in the states it requires me to send my VF37 in to be machined..... while if I went with litchfield I could sell my VF37 and bring the price down to about the same as the SC46. Decision decisions haha, the billet wheel on the SC46 is nice though

Fill yer boots kiddo!

Methinks the spool on that SC46 billet will be a hard act to follow though.

The Gaffer

Hi,

we have the SC46 Billet twin scrolls ready to ship, we dont have to PX your housing we simply charge an extra £150.00.

You mention selling the VF37, who is going to buy it, this is the question we asked ourselves when we needed the exhaust housings back, there is no market for that turbo, in England at least, as anyone who has the twin scroll set up would upgrade in the event of turbo failure and no one would be looking for one to retro fit a single scroll car.

I wont be drawn into a debate on whether the Litchfield turbo is better than ours just take a look at the graphs.

Thanks for your input.

cheers

Hi Martyn,

So true, we have seen this so often, weird.

Thanks for the respone Kev,

That is def interesting to hear, as it's only an extra $250 US for me. And in the US there is a decent market for stock VF36/37's as they regularly sell for $900+ US. I'll buy up your stock VF37's for cheap and sell them over here

Sadly due to the exchange rate and international shipping charges, my costs would be the same to go through Blouch vs you even though with you I get to keep/sell my turbo...... assuming I get $900 my costs are nearly identical (got my hopes up haha).

So if I were to run the SC46, how did the rest of the supporting mods look? Anything I should add to it?

John

The Gaffer

Hi,

mod list looks fine, add a syvecs ecu to release the beast.

Would this power level not really warrant an FMIC rather than TMIC?
