Hi all, getting closer to start spending stupid amounts of money on my car and am starting to wonder about turbos. I've been told all sorts of different things in regards to which turbo I should use. I'm starting to think the T04Z would be a lot of fun as searching through the forums itseems it has only been bolted onto GTRs.

Does anyone have any suggestions ideas regarding one of these turbos being fitted to a 34 ?? the engine will have all the supporting mods done at the same time as the turbo.

I'm not chasing any specific power figure or have any set purpose for the car.

Cheers

Hey mate, I just realised that was you leaving Bel on saturday when I arrived (with my dog). I was searching my head for your plates but couldn't remember who you were.

The T04Z is a pretty bloody big turbo. You would need to do some farily major internal work to raise the rev limit to make any use of it at all.

I seriously think you are better off deciding on a power figure, maybe go for a ride in some powerful cars to decide, and then pick your parts to suit that.

Hi mate, I didn't see your car anywhere, which is probably why I didn't say hi :)

I was out on saturday night with an R33 with roughly 320rwkw and it really looks like a lot of fun :)

what would be needed/recommended for 270-300rwkw ?? I would basically like to keep the engine internally stock unless something happens/is needed.

A T04Z is too big (overkill) for 270-300rwkw.

I'd look along the lines of a GT3040 or similar, plenty of guys on the forums with setups using that turbo in your desired power range. I also wouldn't push it any harder than that - as the bottom end is only limited in that sort of power application.

Ahhh, ok. I had originally been told a GT-RS would be the ideal turbo for what I was looking for, but I keep getting people telling me different things.

For the second round of mods I was looking at turbo, cams, fuel system, coils, oil cooler.

I already have FMIC, PFC, filter, full 3" zorst with hi flow cat, EBC.

What sort of power would be possible with a GT-RS and those mods ??

As Morgs said, a T04Z is way to big for 270-300rwkw.

Something like a GT-RS would be perfect in a low mount setup, or there are a couple of high mount options you could choose (ie GT3040, Trust TD06 etc) but these would up the costs by the time you buy a manifold, wastegate and the required fittings.

GT30 lowmount.

Stock head

270rwkw @ 17psi

Do a search. 270-300rwkw is an extremely common question and many people will have asked, and had answered all your questions that you havent even thought of yet.

Its approx 10-12k adventure if you plan on having it remotely reliable

yes and no. either the GTRS or GT2835Pro will be fine on a stock motor provided its healthy. My unopened (not even a head gasket!) 1993 rb25 was well used and abused on track and strip, running over 260rwkw and still has near perfect compression, so if your tune is good your stock motor might last indefinitly especially if its a street car.

the GTRS will probably be a bit shy of your target, you might see 250rwkw with a good setup. (has anyone seen more than this yet from a gtrs?)

im making just over 280rwkw (at 17psi) with small cams and a cheap cooler. IMO if your gonna chase 300rwkw and over, your best going gtr of some sort.

cheers

start by upgrading fuel pump and injectors to get the 250rwkw i mentioned above (may have to lose the "highflow" cat, as its probably not that highflow). might be possible to stretch the stock injectors with a FPR, as its rumoured that they actually flow around the same as r33 ones?!

I think the low mount GT30 is the best idea - good response, cheap to fit (low mount, internally gated), and plenty capable.

:P

You can get them relatively easy too...

That said, a 3040 should enable you to run more power in the future if you build the motor etc... but will be a little more laggy and more expensive for the time being.

Hey Binky1970....were you at the recent circuit club wakefield day ?

I think I saw your car parked outside the timing building.

Anyways your pretty much at the same stage as I am...except it looks like I might be spending the money on the exterior first cause of some pricks keying it.

However Ive been doing research on the turbos for my 34 for awhile and if you want good response and around 270 -300rwkw id say HKS 2835 Pro S hands down. along with some injectors, thicker metal head gasket and some cams and port and polished head.

If you get the one that comes in kit form than you MAY find it hard to reach those figures as it only comes in the 0.63 housing.....a custom manifold made to suit a 0.86 housing might get you what your after.

You dont HAVE to but for a high mount setup id prefer to change the plenum first to a forward feed style.

Goodluck trying to find a "bolt on" one for the neo....im still searching.

On the topic of high mounts...im very tempted to go for a 3037s highmounted with a external gate. This should definetly get you the power you want and will also look awesome in the engine bay !! hehe yes im a ricer ! :)

If I cant find a bolt on style aftermarket plenum that im happy with than ill most probably go for a 2835 Pro S or maybe even a 2835R with an external gate again this will require some more work with manifolds etc.

Or depending on budget might look into getting either a Blitz K5-660R or an Apexi RX6B......just to be different. everyone seems to go for garrett/HKS or trust.

hope this helps....let me know how you go.

T04Z......hehehe would be awesome but you`d get beaten by most cars out there with more responsive turbos...cause even when you do finally get boost youll be going sideways and not forward ! :)

Yeah I was down at wakefield for the track day. I was driving a mate down there so he could take photos of another mate. I'd like to take my 34 for a few laps but i'm pretty sure the stock turbo would spit the impeller really quickly :D

I was looking at the Trust turbo for the same reason of just being different.

won't the Greddy 33 plenum fit the NEO ??

nope the 33 greddy plenum doesnt fit the neo......you either need an adapter plate which is almost impossible to get a hold of or drill new threads in the cylinder head to make the 33 one fit. The second option is not one I would like to take....so im still searching for that elusive adapter plate.

the trust TD05-18G you mentioned wont make the power your after.......need at least a TD06-20G I reckon.

hahha your car will be right if you just run 0.6 bar of boost ie stock boost. I have been to wakie many times with my car and have never had a problem. But I have heard of reports of 34s running stock turbo and running 0.8 bar or more and blowing up their turbos.

I was there on thursday but I was with the pro concept civic....my car was out of action for track duties...blown turbo to dump gasket.

    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
    • OK, now we are ready to get started. You need to remove the air boxes on each side for clearance. The cover is straightforward, undo the clips on the top and lift the front cover out of the rest of the housing. If it is tight you can remove the air filters first. The rear section of the airbox is trickier. On each side you need to remove the Air flow meter wiring which is held to the airbox with a clip; you need to get behind the clip on 2 sides if you want to remove it without breaking it - unclip the harder side and pull on the clip with medium force, then unclip the easier side and it should pop out The airbox is held onto the intake hose with a spring clamp; you need to get a flat bladed screwdriver behind the spring on both sides and pop them outwards. When you have got them in the right unclipped place they will stay there and the airbox slips out pretty freely. Put a rag in the intake to prevent anything getting dropped in there, and also to prevent you seeing that the turbo seal is leaking oil (as they do). Then. The top of the radiator is held by a steel plate, it is secured by 2x10mm and 2x12mm headed bolts . Remove them and remove the plate Also grab the bushings that hold the radiator to the plate on each side so they are not lost!
    • Next, remove the upper and lower radiator hoses, both are held with a spring clamp. While you are under there, tackle the Auto Trans cooler lines.  Again both are held on with spring clamps, and as mentioned above you should cap them on the radiator side with an 8mm cap, and on the car side loop them with a length of 8mm pipe - this will stop you losing a dangerous amount of AT fluid during the rest of the job If you've been meaning to add a sender for AT trans temp, this is a great time to do it; put a sender fitting into the passenger side line as that is the inlet to the cooler/radiator.
    • Next you need to remove the intake duct (as with pretty much every job on these cars), it is a series of clips you gently remove with a flat bladed screwdriver. They do get brittle with time and can break, and I have not found a decent quality aftermarket one that fits (they are all too soft or flimsy and don't last either) but the nissan ones are a couple of bucks each (ouch).  Once the clips are off (either 8 or 10, I didn't check) you lift the intake duct out and will see the reservoirs Undo the line into the radiator side cap (some bent needle nosed piers are awesome for spring clamps) and then remove the 4x 10m nuts that hold both in place.  I didn't get these pics, but remove the line under the radiator reservoir (spring clamp again) then remove that reservoir. Then you can get at the intake reservoir, same thing, spring clamp underneath then remove it. BTW This is a great time to put in a larger (+70%) combined reservoir that AMS makes..... https://www.amsperformance.com/product/q50-q60-red-alpha-coolant-expansion-tank/ They also make an Infiniti branded and part# version if that is your thing
