Turbo Comparison

[32DET]

After searching on the internet i was unable to find any turbo specs on the Trust TD06-20G (8cm) and was just wondering how it would compare with say a GCG highflow RB25 or even a 2530. Is it a bigger turbo than the other two or approximately the same. Have seen results where it seems to make a bit more HP than the other two on an RB20 engine. Will it be a bit too laggy compared to the other 2 for a circuit/sprint car on a stock internal rb20?

Am looking to make approx 230rwkw

Cheers for any help

Go the GCG high flow because its a stock replacement job. With the TD06 you have to get a new manifold/gate etc but its capable of 250-280rwkw.

[32DET]

So the TD06 is capable of 250-280rwkw and the GCG will reach about 220rwkw tops on an rb20? Is that about its limit?

My engine isn't high on compression all round and makes 223rwkw with a GCG hi-flow at 20psi with quiet abit of fuel put into it and fairly conservative timing (I don't want it to blow lol)... Id suggest with a rb20 that has good compression and a good tune (not so rich + some more timing) 230-240rwkw would be achievable.

I get full boost by 3900rpm with standard cams/camshafts in place and the motor has never been opened. All in all i think too much lag on an rb20 would just be sh*t for street driving as mine's bad enough hehe

Thats what i want to hear cos i bought a CES racing twin dump so i'd like to be able to keep it when i upgrade the turbo as it cost me a frekkin fortune. Also keeping standard manifold etc is a huge bonus money wise. Anyone else have an opinion, anyone with a td06 on their rb20?

If you are in Melbourne then you are welcome to go for a drive it. Im happy with it, but the few 2530 RB20s i have been in have left me very impessed. They dont have the top end but really i dont think there is much difference based on seat of the pants...dont really know how the High Flow compares to the 2530

So were you saying that you were very impressed with the 2530's compared to your td06?

Sorry, just a bit slow today

Cheers!

Different sort of setup really. The TD06 has taken a while to get right with regards to heat shields and thermal control etc. It looks suss as soon as you pop the bonnet.

The 2530s have been punchy, use the std heat shields and are relatively fuss free. A much simpler solution and on a std RB20 you can get 85% of what the 2530 has to offer. The TD06, well most ppl will be content to run 1.1bar and the 220rwkws odd it will make whixh is probably only getting 75% of the fun from the thing. The 2530 seems to need more boost to make that sort of power.

If you are not worred about leaning on the std motor, you can run 1.4-1.5bar with the TD06 and get a bit over 250rwkws. 2530 will never do that.

Personally, having owned the TD06, and gone for a drive in a few 2530 equipped cars...i would go something like a 2835/GT-RS/TD06-20G or something bigger then the 2530. The extra pull is well worth the slightly doughy response.

But hell, its a low compression, short stroke 2.0L, its never going to be great down low, may as well have something worth waiting for

bloke in my town has one of those in his s13 silvia ca18det he made 255hp on dyno last saturday. dam laggy on it but...

[sweetr33]

hey guys, not sure if its relavant coz mines an rb25 but my gcg highflow with vg30 exhaust housing made 258rwkw with 15psi boost. i'd go highflow anyday, although i have a boost control issue its still responsive and not laggy at all. cheers

[Roy]

Just looking in your sig...thats a great result. How do you do that with the std ECU?

[sweetr33]

believe me i've searched for answers, i've pulled the computer out and opened it up to look for a blitz, hks, or whatever chip in there somewhere but its all blank, it has been tampered with though coz i dont have a speed limiter. I have no doubt its been modified somehow coz it does seem odd that mine performs so much better than others with stock ecu.

ive driven a tdo6 rb20det - motor was stock, maybe some cams. stock manifolds, everything. adaptor plate onto stock exh manifold. it was nasty, didnt hit boost till really late, then came on really hard.

nasty, but fun. definately much better choices out there.

[32DET]

Yeah fair enough, so may be a bit laggier but my car isnt a daily driver, just weekender and getting into the sprints/ track days so it doesnt need the best driveability. Will probably end up going the GCG option though due to ease/cost effectiveness of installation etc.

Thanks for replies and if anyone else has opinion/input go for gold!

Cheers

i think the td06 is fine for daily driving... mine was quick only on 10psi with around 185rwkw

checkout the rb results thread my dyno sheets are posted there

given though that my engine may be stroked looking at roys graphs i would hardly say the lag is that bad

however if you are only aiming for 230ish then i would say go the high flow route ... if you want more go the td06
