Hi Guys, Ive got basicly a stock R34 GTT.

The wife has said I can spend a few $$ on it :D :D

I want to warm it up a bit.

Budget is somewhere between $3000 and $5000.

Cant be too loud or Droney afterwards, its a car for daily use.

Whats the recommendations for the best bang for the buck?

I was thinking along the lines of

Pod Filter

Bleed Valve

Exhaust

Intercooler

Is that a reasonable start?

Any recommendations on brands / things to avoid?

Whats the Turbosmart E Boost like? Someone recommended one to me. Better getting this than a mechanical bleed valve?

Any ideas what increase in performance I would be looking at?

Lastly, wheres a place that does a good job at a reasonable price?

I bought it from Unique Autosports and Im quite happy to go back there. Anyone have good or bad experiences from them?

thats a start,

1st things i done

hks pod filter

bleed valve- boost up to 12psi

3'' exhaust,3''high flow cat, 3.5'' cat back

yet to get cooler but its in the process of being made.

saving up for apexi avcr- elec. boost controller

performance gain would be noticible with a good dyno tune,

UAS is where i get alot of my parts from and find them very good.

with just pod,zorst, and boost up i hit 146kw@wheels..

hope that helps..

cheers...

get a full exhaust and dont buy a bleed valve get an electric one instead. you can get fairly cheap second hand items such as the profec b. if your not looking for big hp you dont need the front mount intercooler. air filters also dont do that much. spend the rest of the money on some good suspension and a power fc. :(

I dynoed my car with a K&N panel filter and got 176kw@6007rpm with 1304Nm @4713rpm.

I fitted a 2 3/4 in stainless cat back exhaust and had the cat removed(because we can in NZ:p ) and then redynoed it and got 195kw@6660rpm and 1398Nm @4655rpm

This was on a dynapack pro V5 hub dynamometer.

All figures are at the wheel hubs.

You seem to on the right track, apart from the bleed valve. Forget about that and get an electronic boost controller. But a SAFC might be a good idea as well, to keep it from leaning out at higher boost.

19kw just from removing the cat?

I didnt think they were that restrictive.

Im assuming that was the factory one you removed?

I removed the cat and fitted a 2 3/4in kakimoto stainless cat back exhaust. That gained me 19rwkw.

A SAFC is a super air flow controller, it enables you to controll the air/fuel mixtures by tricking the computer some how. I'm not really up to play with them, but have heard a few success stories from people fitting them.

i'd go:

full aftermarket exhaust (one with centre muffler aswell as rear, since you dont want it too loud)

front mount intercooler

electronic boost control + apexi safcII, or can go for a more serious aftermarket ecu. try get these ones installed at the same time so you don't have to tune it more than once (save $).

Turbosmart E Boost is probably good, but you can also get jap brand EBC (electronic boost controllers) for a similar price. its up to you really.

instead of getting the safcII why not spend a little more for a greddy E manage. You can even find second hand power fc's for a little more than a thousand that will save you from spending money on the safc now when you will probably uprgrade to a a programmable computer in the future anyway.

GTS4 - are your kw readings to the wheels or to the fly wheel?

Check out this months issue of "Speed" the magazine. It has a RB25DET tune guide. It's worth a little look. Also got info on the V35 GT-R as well. Personaly I am adding a R34 FMC, Apexi Power FC with hand controler, air pod and exhaust to mine. Should go well I reckon. You'll get plenty of power before you even think on engine internals :P Just remeber they love to breath and the standard ECU's are full of holes.

the R34 intercooler is plenty big enough for the stock turbo.

It's thicker than the R33 cooler. If any of you R34 guys want to palm off your old stock intercooler let me know and I'll ping you $150 for it.

Get a light flywheel (and clutch while your at it).

Do the exhaust, all the way. Thermal wrap the dump & front pipe.

Diff cradle kit

Panel filter.

Boost controller.

For starters.

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      S1 rb25/s14 starting problem

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
