i have an r33 rb25 and i looking for a good turbo that has plenty of low-end, good responsiveness, and pulls all the way to redline. I'm looking for 375-400 whp and am stuck between a td05h-18g and a td062-20g. which turbo suits the rb25 better and uses the stock manifold? this is my set-up for far:

-nismo 550 cc injectors

-sard fpr

-greddy fmic

-greddy intake plenum

-3" cat-back

-3" down-pipe

I dont think the td05-18g will get you to 400hp the td06-20g should. Mine made 339hp @ 1bar the engine has gone in to be rebuilt with forged pistons and I expect we should see 400hp at reasonable boost levels. Before I killed the engine I drove around on 1.2bar (thats how I killed it) and the difference between 1 and 1.2bar was huge in the seat of pants region... didnt get a chance to dyno it as it developed a misfire and then piston 3 and 6 ringlands went. I also think on trust's website they recommend the td06-20g for the r33 and the td05 for the sr20, i have the huge 16cm^2 exhaust housing and it makes full boost by 4300rpm if you went for a 12cm^2 it should come on a bit quicker but you might loose a bit of top end, my car pulls hard all the way to the redline (which was set at 7500) but we might take it to 8000rpm as it still pulling hard. The only problem with my car (nothing huge) is that to get the most out of it you have to pull it to the redline and then shift, any short shifting will result in dropping out of the power band and the turbo having to spool back up again. If you want more info PM me.

do you think a td05 has the potential to dip me into the 12's? i'm really shooting for 375ish whp and want something a lot more responsive than a turbo that's going to spool at 4000 rpm.  what hks turbos compare to these size mitsu turbos? what about a gt2530?

A 2530 will give u good low down power but not much top end. Its only slightly bigger that the stocker. If u want a HKS turbo go for a 3037.

U will always have to live with a bit of lag if u want near 400rwhp.

u dont need a big turbo to dip into the 12's. Infact from memory someone on here has done a 12 with stock turbo. Something a little bigger would easily give u the power thats needed to pounce ur car across the line for a 12 but its not just the turbo thats gonna help u reach that goal. If u got the launch, traction, gear changes right then ur looking good. TD05-18G would do a 12 in ur car, if a stocko turbo can get someone into the 12's then most turbos wil. goodluck.,

i think i'm going to use the td06-20g with a 10cm^2 exhaust housing. i believe that this turbo would be well suited for the street and still be able to put down 350+ hp. As for 1/4 mile times; the engine is an R33 Rb25...however...the car is a 1996 240SX(lighter) so we'll have to just wait on times slips, and dyno runs.

banzai have Td06-25G's for sale for 2300 brand new. www.banzaimotorsports.com.au

They are advertised for $2400 and Banzai rate them at 600hp. (don't think so)

Very plain compressor housing...looks like a cheap copy...Doesn't look like a Greddy Turbine and isn't plated as such. The picture of the TD05 above it, is a Greddy turbo. The two TD06 SL 20G's I have, looks the same as the Banzai picture of the TD05...except larger in size and rated at Genuine 450hp each. The quality of my TD06's is a lot higher than the Banzai 25G pictured.

Though the Greddy TD06 - 25G had an internal wastegate, not external?????

happy hunting

Phillip

      Wheel refurb?

      The powder coating came in at $250 EACH. The TRX rims got a coat of clearcoat on the outside only.

      Pops when backing off throttle, rough-ish sound through rev range.

      Keeping in mind that I am currently getting flat 10 L/100km on my RB25DET, which means >>500km/tank. I would test this car for vacuum leaks, check codes and AFM signal with NissDataScan as D says, check plugs, do a compression check while they are out.

      It is hard to be specific half way across the world...but it *seems* like it might have a minor issue. Is the idle stable and does it rev smoothly? I would not expect any pops out of what I am assuming is a standard ECU, standard tune, standard exhaust. You can use Nissan Data Scan to find out exactly what is happening when it runs, the cable/software is reasonably affordable if you are not planning on changing the ECU (which hopefully you are not with an NA skyline) BTW your mileage may not be that far off, these are heavy old tech cars, and being NA might mean you use a heavy foot to keep up with traffic....

      Hey guys! Y'all are the masters so figured I'd check in on a few items here. - My engine sounds ever-so-slightly more raspy than the other NA RB25s I've listened to. It's barely noticeable but definitely a slightly different sound. - When I back off the throttle at high RPM, I will sometimes get a pop out of the exhaust, assuming this can be diagnosed as misfire. Some history on the car: - Had an exhaust leak in auction sheet but was claimed to be fixed by seller (bought from USA importer).  - Car's coil packs and sparks were replaced when it was sold to me, but unsure on what the gap is and whether the coil packs are correct.  - A prior mechanic had misdiagnosed a pilot or throwout bearing sound as LSPI/detonation. Had played with timing a bit, pops/raspy sound of engine just got worse. Got timing reset. - Had failed emissions a few times. First time went in as is, failed. Second time, replaced cat, still failed, running rich as hell. Third time replaced o2 sensor, passed. Car still smells gassy though. - Timing belt and valve cover gasket also replaced.  - Gas mileage is... low. about 350-400K per tank.  Any idea if I'm having any serious issues here or does this all sound like normal old NA RB stuff and I'm fine to drive it with the pops/slightly raspy engine? If it'll help, I can get drop a video of the sound of the engine.
