Which do I go for? I've got to the conclusion of the VF35 but although I'm only after about 330-350bhp as my gearbox can only deal with that. I have all the required stuff for my bug WRX jdm to make that just no turbo. Any advice would be great.

Hi Kev best turbo for you is VF35 or TD05-16G,problem with TD05-16G out is so many chinese fake/knock off which will last maybe few days or just don't get usual boost or just blown...
VF35 is best turbo for you at the moment,if you find genuine TD05-16G,take it...

Yeah theres one for sale on here a genuine td05 16g. I think i'm going to take it then, what will i get out of it?

TD05h-16g is a good choice I think, but you will need a compressor cover converted to front entry as the original and real TD05h-16g where off early classics so had 90 degree bends on them.

See Andy Forrest, he sells the front covers

Should get 330-340 max from a 16g I think.

My friend brought TD05-16G recently refurbished Turbo Dynamics for 350£,i think 350£ is fair price for genuine TD05-16G.
SC36 is great turbo,but price around 800£ is little bit pricey.
If is possible contact Bob(Aztec Performance ltd.) about the price and i think this turbo will be good for 330-340BHP(some good one have proven 350BHP)

352BHP is great result for TD05-16G,this is something which i've seen on some TD05-18G on WRX.

Yeah so I'm guessing the VF35 is the better option as I do not have to change the compresser housing? I'm to keep my eye out for one, the TD05 16g i was going to buy doesnt have much history with it so.

The guy PM'd me about the TD05 16g and its a genuine td05 16g,was on a car owned by john felstead previously and have been assured its a good one. I dont know who John Felstead is?

Hi Kev PM here Bob about the TD05-16G at first.
How change compressor housing,i'm sure someone know how to do(just ask near to you),new housing cost around £90(maybe more)
And if you are need housing check the breakers these usually have,if no drop email to info@andyforrestperformance.co.uk
And about the John Felstead here is profile Scooby Sprint Championship http://www.scoobysprint.com/scooby-s...mpetitorid=102

Yeah its got the the compressor housing changed so its all good, sounds like a decent one doesnt it. I'll check out the guys profile. Cheers Jura your a star.

One advantage of the TD turbos is that they can be serviced. The IHI VF series (or at least the VF35) cannot. With similar spool characteristics, I would go for the TD (should be cheaper new or 2nd hand also).

I'm quite lucky as turbo technics like 5 min away and is just around the corner, I'm going to ring them up tomorrow and pick their brains.

I got it wrong its actually Turbo force. http://www.turboforce.co.uk/sports.html - I'll give them a bell tomorrow and see what they have to say before I finally make my decision....haha

kevaldo

iTrader: (4)

I jut spoke to the guy at turbo force and he suggested that a VF30 or VF35 would be ideal, as for the TD05 turbos, you can change the housing but even then he said they then do not seem to fit the best. Mounting points are different and other stuff regardless if you change the housing.

VF35 quickest spooling turbo next to TD04. Will produce 340 bhp and similar torque with the right supporting mods. Had one on my MY99. Cracking turbo.

WhiteWagonMan

iTrader: (34)

yeah the 35 is a superb turbo for a fast road car,also had one on my last car.DONT change the oem intake pipe for a silicon version tho(LIKE I DID)as this will create bad surge problems which is a nightmare and almost impossible to map out.

John is one of the 'Old Guard' on here.

I was at Zen speaking to him when his car was on the rollers with that turbo, iirc it was about 340bhp but I'm sure I remember him saying it was a big 16g rather than just a normal 16g with front entry conversion.

A front entry td05 is a cheap way for a decent turbo, I'm just sorting one for my mates bugeye and I bought a front entry converted cover 2nd hand for £60 and a td05-16g off an early wrx for £110. So for £170 I've got a turbo capable of 320 or so bhp.

For some reason anyone selling one with the cover fitted (which takes about 20 seconds to undo the large C clip holding 90° elbow on, lifting it off and then putting the FE cover on) wants loads of money for them. You can get a front entry cover from Andy F for about £70 and (if you're good and keep an eye on eBay) a Td-05 for peanuts, especially when someone just lists it as 'impreza turbo'

When I did a power hike on my uk turbo a few years back I went for vf35 but didn't really think about the td05 route. If I was doing it again I'd go td05 fe purely because most people want £300 for a vf35 and I reckon a FE td05 is possible from as little as £150. They are good strong blowers too and I've always liked the power delivery from them.

sorry to but in but what is ment by td05 16g, is that a standard turbo on a early classic and what is ment by swopping the housing,,,, what car would you get a housing off ?

kevaldo

iTrader: (4)

TD05 16g turbos are originally used on Evos, thats why the housing is different. I few of the guys on here can change the housing for you. Andy forrest can sort that out for you as it said further up. I have not got myself a TD05 16g and its MINT!

Ginge !

i currently have a VF23 on my classic STI so is this upgrading or not

id like to do DIY as much as poss if im honest with my car as its part of the fun owning it

jameswrx

iTrader: (4)

I'm referring to the td05 (like you say) that's fitted to 92-96 wrx's. They come with an upswept inlet as the inlet pipe doesn't pass under the inlet manifold like your sti.

You can get a front entry converted cover which is just the original cut off and a straight inlet alloy welded on. Fitting is as easy as I explained above.

You can also get a 'big' 16g but I'm not 100% what makes it 'big' think it's a larger exhaust housing?

As far as upgrading from a vf23, I think they'll ultimately give slightly more power but probably not enough to justify the swap. I don't think the vf23 is too bad, if it was a vf24 then it'd be worth it. I think I remember reading vf23 will do up to about 320bhp. Personally if I was wanting an upgrade from a vf23 I'd go vf34 as it's a good step up from the vf23/24/28/30/35

Mind you saying that it depends what you're doing. If you've got an ecu to go on and it's getting mapped anyway then it could be worth doing as you'll prob gain a bit.

Ginge ,what mods do you have fitted to your car,and what bhp/torque is it currently running at ,as i have seen a few newage wrx's with a vf35 fitted making 320-330 bhp,which should not be too far away from your a well sorted vf23 .

Time moves on guys why not move with the times fit a billet Sc 36

johnfelstead

James is correct, mine was a Big 16G, it uses a larger inlet compresor wheel, it's great if you want an engine to produce lots of mid range torque, which was my aim with that engine.

It produced 338BHP, 347lbft on Zen's rollers on that day, with over 300lbft between 3700rpm and 5500rpm.

if im honest i dont know the power of my car but it is a sti V3 with a mines ecu and it goes average well if that makes sence and holds around 1,2 to 1,3 bar and peaks around 1,5 bar i think

im changing injectors, fuel system. 3ins decat to tail, equal manifold, erm other stuff oh and ecu and just looking at mods for it for when its bolted back together without going silly or no benifit

basically im interested in how it drives rather than what i number i get on a sheet of paper Vs overall cost to find a balance if that makes sence
