R34 GTT Upgrading Stuff

Okay, so I've got my dream car, until I can afford myself a R35 haha. I love my 34, it's a manual 98 model. So far, engine wise, I've added a GFB 6 Preset Electronic Boost Controller. On the way, which will arrive in the next week and be in by the 28th, is a 6 boost Exhaust Manifold, 1000cc Injectors, Nistune ECU, Madcat intake manifold, fuel rail and 90mm throttle body, Walbro 460 Fuel Pump and my big 900mm Front mount intercooler. I'm planning on getting this all in within a few days of flying back home from work. I know what I'm doing adding all this stuff, it's really not hard, just a bit fiddly. I've got a few questions though..

 

So obviously the upgrades listed are quite substantial, and will allow me to handle quite a bit more horsepower, but I'm wondering what Turbo to upgrade to? Or even better, whats an easy way to know what turbo I can fit? As most of you would know, my manifold turbo mount supports a T3 fitting. I'm wanting at least 350HP at the wheels, but if it's possible with these specs, I'd love 400HP at the wheels. I understand the turbo plays a bit part of this, hence why I need some advice. And yes, I am aware a tune would be needed to support the rest of the mods.

 

My second question is related to Anti Lag. So my Nistune ECU I'm getting is plug and play, and I've heard that when it comes to anti-lag, you can have it wired to a switch. Firstly, is this possible with a Nistune ECU? And if someone could explain how it actually works? As I'm genuinely curious how a little 12v active cable being cut on and off can enable something that's programmed inside the ECU? Unless there's more to it.. cheers everyone!

Anti lag in bin. Just not worth doing.

You can fit any T3 turbo, because you're going to need a lot of fabrication anyway, and anything T3 both can and must be made to work.

Get a EFR 7670 in the T3 format. If you can return the manifold get it in T4 TS. This is the best option as it comes with a bov and boost solenoid too. If you can return the manifold, I'd just say go buy my kit which comes with literally everything.

Failing that, GTX3071 0.82 rear. But if you are buying new, the EFR is a better unit, and well, WELL worth the small price increase which is probably absorbed by not needing to buy a BOV which you would for the Garrett.

It is triggered by road speed and can also be wired to a switch. Once a particular defined road speed is set, it is turned off.

It is for launch only and can't be used as rolling anti-lag. Also it is limited to only 0 degrees of ignition timing and can't take negative numbers. Great for building boost for good consistent launches at the drag strip.

Just wondering why you'd request I return the manifold if I've got a top of the end manifold for the T3 fitting, which if you research, 99.999% of manifolds available are all T3, so there's something working right with that size turbo fitting and the Rb25 engine. I knew there would be someone with sarcastic response tell me to do something completely opposite to what I've requested. I asked what turbo I should use, not what turbo I should use if I had a totally different turbo fitting, which is impossible to find anyway. And for my turbo lag question, It was for show, and the occasional launch on the drag strip from a standstill. I've seen a few r33's and r34's parked up at car meets revving, then a few seconds of silence, and their revving turns into popping, and spitting flames at redline, instead of just the normal redline effect.

The turbo is the most/only important part.

It is the part that defines if a car is decent or not. The best turbo really right now is not T3. You buy a manifold to fit the turbo you want, not the other way around.

Can buy plenty of OK choices for the T3, but if you are going to the considerable expense of a full build, its better to start with the turbo first, then get all the pieces to support that.

So my entire build is out the window and is total dog shit because I have a T3 instead of a T4, that shitty T3 isn't going to get me any horsepower at all hey

What about, a T3 to T4 adapter flange? In my head out kinda doesn't make sense because it's still going to be restricting airflow that tiny bit, only a few mill difference between T3 and T4, however, the bigger better turbos can go on it, so the end result would be better if I just used the adaptor right?

      Did this end up working? Did you take some pictures?

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
