Thanks for the info mafia .. do the garrett gt3071 turb need new lines too ?? i have a stainless manifold... but i will need to get a new one for the external wastegate if i go down this path..

thats exactly right - GCG highflow is the most cheapest upgrade ($2k) and it bolts straight back on, no adjustment to oil or water lines.

2530, you'll be spending $300 on oil and water lines, and lots of time and stuffing around... I've been there and done that, pain in the ass.

If I could do it again, I'd get a high flow. But, I can't do it again..

unless the kit specifically says that the turbo will use all standard RB25 oil and water lines then yes.

ALL non RN25 turbos need new water and oil lines, except for the kits the specify that they will use the existing factor ones - which are rare as f**k.

i thought i would quickly check with yall first...

i have a 33 with ems cooler exhaust new turbo manifold etc..

and want to upgrade my turbo... i have decided on a Garrett gt3071 with .63 exhaust and with an internal wastegate....

does this all sound like a good setup ?

Cheers thanks for any feedback

I know a couple of people who have fitted these 3071r .63's to SR20DETS and they suffer from really bad boost creep. One of them is having the internal wastegate modified (enlarged) to try to alleviate the problem.

surely you have learnt something in the last 2 pages of advice and previous topics in the forced induction section.

cheap turbo's are cheap for a reason

ebay turbo's are a no no

mystery (unknown spec) old school t04 combos are lag monsters usually

what do you call a laggy turbo?

one that comes on at 3000?

one that comes on at 3500?

one that comes on at 4000?

one that comes on at 4500?

one that comes on at 5000?

hehe thanks paul i know you get what you pay for !

so a 2530 hks would be a good upgrade on mid to high boost ?? compared to the 3071 ?

The GT-RS kit, for what it's worth, was a pretty easy thing to install.

Turbo bolts up to the existing manifold and exhaust no probs.

New oil and water lines need to be used (come with the kit) and are also pretty easy, with the exception of the water line at the back of the engine block which is a b*tch to get to.

It's a solid day's work, but will net you 230-260rwkw on an RB25.

Worth considering for what you say your goals are. I imagine they would be pretty responsive on an RB20, as plenty of the SR20 guys use them aswell.

The GCG Hiflows (RB25) all seem to be getting similar power figures.

      Yeah since those first 2 replies I actually went and put some 98 in it and tbf it's already doing much better than the 95 (which is weird and makes my inner tinfoil hat wearer think the 95 was a crap batch), getting 8ish around town. Again, wonder if it takes a while to stabilize if the fuel is changed a couple of times. I swear cars used to just either run "well" or "s**t* in my 20s, none of this fuel optimisation business haha

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Any number of different ways. Have the coils draw sufficient current to provide contact wetting. Use different contacts in the switch, either by material or design, better suited to the low current drawn by a relay coil. Etc.

      Hmm, how does the R34 manage to have headlight relays then without getting excessive carbon buildup on the headlight switch contacts?

      Not R7R. Meant to type R&R, obviously enough.

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Bugger "making it look stock". I put one conventional internally fused Hella relay behind each globe. I just pulled the plugs off the back of the globes and built new loom segments with male and female plug parts to match up to the original loom and the globe, and used the original power wires to each globe coming from the switch through the original loom plug to trigger the relays. Ran a big fat (also separately fused) power wire across the front of the car to feed all the relays. It's as ugly as f**k, but it is wedged down between the headlight and battery on the RHS and the airbox and headlight on the LHS, and no-one ever looks in my engine bay, and on the odd occasion that they do I simply give no f**ks for what they think. Fully reversible - not that you'd ever want to. For f**k's sake. It's a Skyline. They made million of the bloody things. We've been crashing them into roadside furniture for 30 years now. There is a negative side effect to putting relays on the headlights. The coil current is too little to properly clean the contacts in the switches and they get blacked up and you have to open them up every couple of years and clean them manually. I have 25 years of experience on this point.
