Hey SimonR32,

As little as possible :whistling: But probably 7500. My 25 used to make 430hp@7400 and still make power on the way to 8000 but i didn't like revving it that hard. I should post up a dyno graph as its interesting to compare it to your T67 result on E85. Actually your graph was what convinced me to go T67!

In a nutshell 3037 in front until 3500 from my hazey memory from last night while i was trying to digest all 90+pages... but after that the T67 romps away :thumbsup:

Do any of you guys with the T67 have a torque graph you can post- I don't care about the numbers or scaling, i'd just like to see the shape of the curve?

DVS JEZ- i run -5's on the 26/30 in my GTR. Just awesome. Its in the shop now for it's final tune...before i sell it :( to provide me with some more fun tickets so i can finish my little track car :D

The 6boob jobbie really does make quite a difference- i picked up 30hp while dropping 2psi on the 3037!

BTW the 26 is going in my S13

8000rpm minimum on a RB26, I think that's even stock... If it's built well 9000rpm shouldn't really be an issue either!

Yeah the internal gate one they do comes in an L2 rear, might be worth trying.

I had the crazy idea that this one would be better though:

www.ebay.com.au/itm/Turbocharger-SR20DET-SILVIA-S14-S15-TD06SL2-18G-Turbo-/270893185830?pt=AU_Car_Parts_Accessories&hash=item3f127dfb26

The TD05H-18g has about 280kw in it with a 10cm housing, maybe the L2 rear in that one will free it up even if its a 8cm.. Thats my thoughts anyway.

Bro can you PM me a price to put a gate adapter on a stock manifold, cut and shut my dump and weld on a screamer? Seriously thinking about a kando again lol

Simon,

I was being facetious- sorry. It'll rev to whenever it stops making useful power. That said, yes built balanced blueprinted etc etc. But i will probably stop around 8000. I remember when Gibson motorsport stopped revving them past 7000 towards the end of the Group A era, i don't remember the exact figures, but engine rebuilds went from a a few hundred km's to into the low thousands.

I'm not chasing every ounce of power, solid performance & reliability is my goal.

Thanks for the torque graph.j I'll scan my 25 printout tomorrow as a comparison and post it.

Doing the dame thing for dori34 this sat

blakes work is sexy and he knows it..

very happy with the way he done my mani job :D

GTScott, Just go with the kando man! everyone says how brutal they (and the trust series) are on boost, i cannot wait to experience this myself.

kekeke, just need to keep control of det on my setup.. remember its sitting on 10:1 CR and i dont really want to decompress it

if i can find evidence to support that ill be fine ill probably look at getting a TD06SL2-18g 8cm T25 and get Blake to hook up a gate for me and mod my dump.

Here is the 3037s graph showing torque and power. The pink run was the original turbo, the red one was after it was rebuilt by GCG.

Look for a faint pencil line, that is SimonR32's run on E85. It shows T67 a little behind the 3037 until 4500- there's nothing in it so you can say they are roughly the same- after which, the T67 walks away.

Both my runs are at 19psi

I know i said mine made 430, it did, this was re-tuned after i plumbed the external gate back into the main exhaust which lost some power in the top end - not shown in these graphs.

Why if only running a 2L would you want to run the bigger turbine and associated lag of the TD06? Especially if you are only flowing the lbs of air from the smaller 18G compressor?

Any change of a bigger dyno? cant see anything :)

If you attach the full size it will shrink it down for normal view then you can click on it to see the full image.

Its only a smaller trim compressor, it should breathe easily through the L2 rear. I want to keep my rear side fairly free flowing because I have the little 10:1 issue to keep in mind.

I consider this: if a td05h 18g 10cm can do 280kw, a td06sl2 18g 8cm with an external gate should be able to match it. hopefully the 8cm vs 10cm can match in spool also.

On the same token is Eiji could make me a T25 10cm TD05H-18g I would go for it :)

Yeah can't see shit! But if you want to compare a GT3076R (same as HKS 3037) with the T67 see this post

And here is a comparison of a 3076r with the same fuel, on the same dyno on the same day... Mine runs a little more boost, but this one has tomei poncams

Am i missing something re the compression of your motor? Compressor wheel gives you certain cfm of air. The engine makes a certain amount of hp with that airflow. The compression ratio doesnt increase or decrease back pressure or flow. It influences where you make your power and the amount of ignition the engine can take.

So not sure I would agree that because you have a higher compression you need to run a bigger housing.

OK more or less the same CFM of air (with a resultant HP) will have a higher EGT with the higher comp.

The TD05H-18g Jez tuned for me recently on a 9.5cr motor would start pinging once we hit 16ish psi. Pulling timing wasnt helping..... I have a feeling the 8cm IWG TD05H was just a shit balance when driving a big compressor on a high comp motor. It comes on boost very early and strong, just didnt want to take the boost.

It did make 207rwkw @ 15psi on a Mainline dyno, but hey we wanted more :whistling: It did not appear to be an issue with the way it was being tuned as I was on site watching timing and fuel trims being altered to combat the ping.

well i have decided on the T67-25G

will be putting it on a 6boost mani with either a turbosmart ultragate 45 or tial 44mm gate laugh.gif

just have to save money over the next 6-12months but ill be buying turbo first in the next 2 months so i don't change my mind

You can thank photobucket for resizing it, I'll have another go tonight when I'm home.

Are they both on E85 or 98?

Both on jew mix, 50% E85 and 50% BP98

Which is the T67 and which is the GT30R?

T67 is the slightly lazier 480rwhp and the GT3076R is the 436rwhp

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
