Hi Guys,

I have just bought my first R33. Yesturday the rubber pipe broke off from the boost controll and my boost was hiting (whats looks to be) 5 on the in dash display. before i this happened the boost was only getting up too 1-2 on the display. What is the standard boost the car should run. I have also been told not to boost the stock turbos as the fins with break. :P..

The car has a boost controller but its turned all the way down.

How much would a after market turbo cost?

Thanks for the help,

Kyle

Hey buddy

Stock boost is about 7psi.

Have a read through the forced induction section of the forum, you will find heaps more info there :P

You can boost the stock turbos up to no more than 14psi which is what is recommended, but thats with supporting modifications such as FMIC and turbo back exhaust.

It should run on or around that line between 0-7, and a turbo upgrade can cost from 1-5k for something good!

I think high flow'd turbo's are around $1700 all up, but there not gonna do you any good with the stock ecu.

Thanks guys, its a good place to start. how much would a good turn cost, I was speaking to a guy on the Gold Coast and he said he spent arund $700 for a dyno turn,

What does FMIC stand for, Sorry for the stupid questions but im new and its the best way to learn. lol

Where could i find instruction on how to hock up a boost gague.

Thanks in advance.

You'll need either a piggyback ecu or replacement ecu to be able to "tune" anything at all. Otherwise the most you'll be able to do is adjust ignition timing which is hardly worth paying that much money for.

A good dyno tune will normally cost around a minimum of $150 just for the tune. The $700 you mentioned would have included extra stuff, and maybe tuning more than one thing. I've only had a Apexi SAFC piggyback tuned which isn't that hard so cant give you a good estimate for say a full replacement ecu sorry.

FMIC is Front Mount InterCooler. You should be able to find some good info on these forums by using the search button... :P

there is a small nozzle on the back right hand side of the engine (if you're facing forwards, or left if you're at the front of the car looking in the engine bay) - it has a small rubber thing on it to block it off - you just remove the rubber stop and connect your boost guage hose to that nozzle. as for mounting it etc. well thats a bit more difficult and entirely up to you...

generally, if you're not sure, get a friend or workshop to do it...I'm kinda in the same boat as far as my technical ability. I know how to do fairly simple stuff but I'm no mechanic. :(

Oh, and stock boost is 5psi up to 4500rpm where it increases to ~7 psi. But if you've replaced the stock boost solenoid with a boost controller you'll probably want to set it anywhere between 7 and 10psi but no higher than 10 to protect the stock turbo. If the turbo shatters (which it will at anything around 14psi) it'll cost more than just a replacement turbo...

Like others have said, to make an aftermarket turbo worthwhile, you'll need to spend around $5K including the turbo itself...and maybe more to get the best from it...

    • 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
    • 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.
