Td05 18g Onto Rb25

[gtst93]

Hi I have been looking at upgrading my turbo with something that will just bolt straight on. I am looking for around 260rwkw. But I want to keep the lag right down to a minimum I have been looking at a Trust TD05 18g. I just want to no if anyone else has used these turbos before or no of anyone who has and what results they have had.

My car is a R34 skyline

thanx

No way on earth it will make 260rwkws. It should be responsive though as its a pretty small turbo.

This is a guess, but std EVOs use to come with turbos from the TD05 series... for that power a TD06-20G is more the go, though im yet to see a T3 flanged internal gate one make that sort of power.

General consensus is a 2535 or a GT-RS is the better avenue to pursue, or try reading bullant_47s thread in forced induciton on the GCG Hi-Flow with VG30 rear housing

You don't need to get the VG30 rear housing if you are starting with an R34 as you already have a larger exhaust housing.

GT-RS or GCG Highflow are the best bolt on options.

2835ProS for a bit more power.

Evo Turbo's up to EVO III are TD05 16G.

the newer EVO's have been using something else.

I had a 16G on my VR4.

it was pretty responsive on the 2L.. I'd say 1bar boost by 3500rpm in somparison to the stock turbo (which is a td05 14B) makes 1Bar by 2900 I think

TD05 on an RB20 sounds like a winner.

[BHDave]

td05 18g's seem to be good for around 220-230rwkw on sr20's. I think you'd really be pushing it on a 25 as it would choke up at the top end.

cant go past a well matched garrett GT series turbo, they are so cheap now

I had a the same turbo on my GTT and it made 350HP at the Hubs so about 250 hub kw which would be 240rwkw at 1.2bar. It is strangled up top tho, dropped to 1.0bar by 6000rpm

This dyno shows it (the software says Flywheel but it's the power measured at the hubs)

<{POST_SNAPBACK}>

TD06-20G is pretty good balance between response, a reasonable power figure at sane boost, and the good old turbo kick/feel....on an RB20 that is.

Even on an RB25 where it should be able to punch out 260-270rwkws, i would be surprised if on an RB25 a GT-Rs or GCG Hi FLow could match it for response and power...

[gtst93]

^^^^^^^

So it I able to make the sort of power that I am after then.

how responsive was it?

Was it nice to drive?

I just want it for drifting so i want minimum lag that is why I was going for the smaller turbo over the bigger.

I have a mate that has a TD06 25g and it is to lagy for what I would like. I have been also told that their I a guy over in Victoria with a GTT with the same set up as mine and he is producing 270rwkw on 1.2bar.

[IanH]

Here's the Boost Graph - It made 1.2bar by 3200rpm and held that til 5000rpm before slowly dropping back and holding 1.0bar by 6350rpm til 7250rpm

Ignore the spiral effect - the operator over-boosted it at 1st

That was with a completely standard head/cams etc just lots of bolt on bits. I was aiming for Tomei 260' Cams and Pulleys for even more poke.

It was fantastic to drive - good off boost preformance too.

year thanx

did you have an electronic boost controller when you had that done

i have looked at the TD06 20g and their is not much difference between it and the TD05 18g. but the TD06 would have a lot more lag.

go BB high flow yr stock turbo at gcg

So much money & hassle for so less gain with the td05

[gtst93]

a HKS GT2535 output is 340ps

a tD05 18g is 300-400ps
