Hybrid turbo

[willsf1]

Im nearing the completion of a gze-gte conversion on my aw11 im gonna run a td04 since i really dont want the lag associated with a t28 or td05. Many people tell me the td04 will be too small, im only running stock injectors on stock ecu but plan to upgrade those soon and I dont want to have to upgrade the turbo then. I was wondering if its possible to put a td05 compressor and housing on a td04? I dont know much about hybrid turbos but figure why machine a td04 comp housing if a td05 one will fit on a td04 core? Any input would be hepful

get a t3/4 hybrid, lag smag youll love the power. Are you running stock 4agze gear (injectors ecu...) or bluetop? If gze, a td04 will be too small, i saw a td04 dyno running 10psi and a link, max power- 113kw atw.

You want a t3/4 running about 15 pound, will be absolutely perfect running 90% duty on the injectors, and youll be up around 160kw atw... just trying to help

every1 says they dont care about lag til they have loads of it... tdo4 can do 135-145kw and will still have a fairly usable powerband. if you want any more you are going to have lag , its up to you to decide how much
pick your target power figure and choose a turbo that will be capable of that but still retain some response. no point having a moster turbo but not utlising it.

personally id say a td04 is too small, fine for 1500cc's
no a td05 cover wont fit on a td04 core, i pursued this a few years back.

FWIW someone on this forum has an aw11 that does 12sec 1/4 miles with a td04 IIRC

[Malcolm]

also worth noting that GSR's can do 12's on the td04 also, and they're 1.8L

[crnkin]

very true, but you could do 11's on a t3/4 and lag is just one tradeoff for mega power i guess...

Thanks for all the input. I was thinking T3/T4 but im a student on a budget! Also ive become used to the driveability of the sc and dont really want to loose that but was hoping for 150+rwkw. Ive heard of guys using vf8's and td05's but with useable power from 3500-4000? Im not after a drag motor but a more flexible street/track application. Would a td04 supply say 14psi to redline or would the volume be insufficent after say 6500?

learn to read compressor flow maps and find one for the td04, then you will know! Seriously I think the td04 will be great, and you wont need to worry about upgrading injectors, ecu etc. a t3/t4 of any description would be a waste without fueling upgrades to allow you to use it to it's full potential.

agree. TD04 is pretty well suited for the standard setup.

Although if ya want to get some real potential out of the motor go bigger with the likes of a T3/T4 or td05h. Lag aint that bad at all and the difference in overally power can certainly make up for it.

As all_fours said, don't worry about ecu or injectors, they'll be sweet.

Speaking of compressor maps and turbo reading heres a few links:

bah td04 blows goats ..
run either a t25g or ballbearing t28 turbo ..these are your best option for minimal lag and good power..
the t28 can hit 150kw@wheels no probs
but bare in mind that your injectors will be pretty much on their limit at that power

i had a td04 14b on a sohc vtec turbo, 1500cc, and it was pushing its max.

I agree with matt, look at his dyno graphs! cant argue with that!

Which SIZE of td04? There's 9b's, 11G's, and 13G compressor wheels on them, makes a lot of difference. If its not enough for you, go up to an ex - VR4 td05h-14b, that'll be MORE than enough and its comparable in size to the T28. Also only costs about 250-300 second hand....

[willsf1]

Thakns again for the input I think a td05 is on the cards once i get feul and comp sorted. The td04 is out of a late wrx not sure on the specs and turbo flow charts only tell half the story , depends on geometry and VE of the engine. The "real world" of experience is much more hepful.

my old setup was with a td04, on 10psi it made 137fwkw, but i'm going for bigger cos i want more power!
