My 30DET is now running TDO6H 25G, budget build with Hybrid manifold and 50mm Turbosmart gate. Turbine is the 11 blade option with 12cm housing. Tighe camshafts correctly dialled. Track car, chasin

With the 12cm a bit more energy was put into trying to get it to hold boost. Didn't exhaust ourselves as I dont want to spend too much $ fiddling around when the setups are going to get swapped. Main thing is we get to see the character and idea of response and numbers. But curious that it wasn't anywhere as simple as getting the other combos to hold boost.

This is similar to what I found with the 1.06 tial. Nothing in the Turbosmart instructions worked so I had to design my own setup using the 5 port. Buggered if I would be paying a workshop to diagnose all the issues I have had so far...

Anyway, good luck with the HTA, should be a good thing on the 25.

Well after some head scratching found a problem with the Turbosmart gate. Will be surprised if its the cause of the boost problem but either way the thing needs fixing as the bottom of the alloy housing is pissing air through the valve stem due to a failed o-ring. Seems to be made of rubber which has naturally hardened and failed. So in theory that would make the thing spike or run higher boost than expected but will see.

just got my rb25 tuned the other day with the td06sl2 10cm, greddy copy, 440cc injectors, aftermarket throttle body, custom low mount steampipe manifold, full 3 inch exhaust.

Car made 268 hp on 15 psi and it started to lean out on full throttle.. and this is my problem now D:

wasn't your tuner able to diagnose this on the dyno?

I can have a guess and say it was your............... wheelnuts? I mean it was on the dyno... why couldn't the tuner work it out? Its almost impossible to guess what did it without getting you to check nearly everything including the wheel nuts, but it would have taken said tuner under an hour MAX.

Argh this R32 seems very resistant to do what it should do. How was the 73HTA behaving in terms of spool compared to the other setups? It's a shame to hear it sounds like it might now get its chance in the sun due to external factors.

Very keen on this also :yes:

Nothing amazing. Nbew fuel system is about finished. Turbosmart parts arrive today. So hopefully over the weekedn get things sorted and get theh thing fully tuned on Monday. Only the 73HTA is already off :) I looked in the mirror and deep down inside I knew I wanted to run the TD06H-25G...ie a Man's Turbo :)

The 73HTA had near identical spool and looked as though it would tune up ok but ran out of fuel. I canned it as wanted to see how the gruntier 25G was going to go response wise with the smaller 10cm housing. Also want to make sure that I have the biggest dirtiest turbo I have on there to check the engien as there is possible there is a restriction somewhere in my setup that is capping power as nothing tried to date has allowed the thing to make the power of the RB20 :(

So need to rule out the fact that my kinder surprise engine isnt somehow a bit ordinary at making power. Its got good bits, Good compression, pressure. No blow by. Tunes up right...we did run out of fuel but it doesnt really make any more power at 20psi then it does at 15psi so ?!?!?!

^ ditto, but I can see where you are coming from. Shame about the resulting what-ifs, but if it spooled well and we know that it is only a few lb/min lower flowing than the 25G (~54lb/min vs ~58lb/min?) then it isn't a bad indicator.

Will see how the 10cm housing goes. If it is somewhere between teh 8cm and 12 cm (makes sense) than I will grab 40-40rwkws through the midrange which given the 25G wheel gives me the sort of power that I am after ...well not being able to put a 10cm housing on the 20G or 73HTA is a killer.

Gutted this hasn't gone smoothly as it should have, especially for you - thanks for sharing the results and big ups on trying! I know how much of a mission a SINGLE turbo swap can be.

:blink: i made 267kws on pulp @ 15psi...you should be pissing in around 350hp atws...

You need more fuel? E85 Walbro pump, Bosch 1000's and ethanol in the tank... Win.

I think he has bigger issues at hand man...e85 is your answer to everything...:laugh:

stock GTR injectors yeah....invest in IDs...Nissan will love you :D

from my experience, unlike bigger turbos the SL2 doesn't get a huge improvement from e85 anyway...its great on Pulp too...18psi should see you around 280kw ish...

I agree with the above. The L2 20G is a fairly efficient item where it gets close to its maximum flow without the need of E85. Dont need to convert to ethanol to get the right power out of it.

      GReddy Injector Help!

      By Duncan · Posted

      Ultimately, if the tip is not far into the runner and the o-ring seals, then you are in business. Have you applied pressure to it as is? It is not really a problem for the injector to twist once it is bolted down, the oring seals it and you don't want it jambed into the oring too hard The plenum is intended to take multiple size lower injectors with different adapters, but the way you have it is fine if they seal.

      Compatible rear drive shafts R34 N/A?

      Are these the Dmax ones you are in reference too? https://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35#description Not a bad idea to get the uni flange ones. I have sent just jap an email too. Will see what they say lmao. Only thing is the Dmax ones are on a big back order. Low key anything will be better then my OEM ones I got as they are sounding like popcorn when I go under load lmao 😂☠️🪦.

      Compatible rear drive shafts R34 N/A?

      By GTSBoy · Posted

      They should do. I have S14 (or something S chassis, anyway) driveshafts in my R32 (because my diff flanges have 3x2). They're the right length. When you go looking for R32/3/4 driveshafts (for turbos), they're all the same thing, so are the same length. So there really shouldn't be any reason why those cheapies from JJ won't also fit an R34. R32/3 NA should also be the same thing. The (3x the price) D-Max ones are uni-fit. They have 5x1 and 3x2 bolt holes and say they cover all the cars. So that would also suggest that they are all the same except for the flanges. And in that case, the flange goes both ways. I'd be buying the D-Max ones if I ever have to replace a shaft. Because that will open up diff options without needing to juggle shafts also. Juggling shafts is gay.

      By ChoppedSpots · Posted

      Yeah with the adaptors they do look like the photo above - just the fitment within the plenum itself and then further with the rail to the intake is questionable - we shall see tomorrow hopefully once I get some replies from Aeroflow, maybe those bosses are the missing piece....

      Should be fine, if you have it sitting too far in, you end up just spraying the walls and have shit idle. You "can" run them like that, however I don't think it's a great idea (also depends on your plenum, might be good to just get the injector bosses first, mock it up and see if you need to get the bottom extension) Ideally your injectors, with the extension should look like this  (Not my photos, just Google)
