Critique My Set Up

[R31Nismoid]

Thanks Adam, I figured the 20% additional flow should be able to cope at this stage. Seems like I was right, I just saw Nismoid mention minimum 700cc in another thread and started to wonder...

500-550cc injectors will not allow -5s to perform to their full potential power wise as they will not slow enough.

700 are needed at a min, which is the next "size" up in the jap brands IIRC as there is a gap between 550 and 700 where nothing fits

[GT-R32]

Just as my stockies would top out at 305rwkW these will top out at 360rwkW... My bottom end will be annoyed prior to this though.

Cam gears and 100k service bits to buy, then I'll book it in. Might leave it a month or so and revive this thread as I have a bill coming up on another car this month...

[Nee-san]

im with you GT-R32 everyone always burns -5s if the word "response" is in the thread. Im about to upgrade to -5s on my 26, ive got old school Nismo steel wheels on my car now, it makes 311kw and they are maxxed, it makes more boost on a cold night lol but if its warm im lucky to make the 18.5psi its tuned for, even in 4th gear with a full pull. comparing my dyno sheets to the cars with -5s, my car will be the same if not less laggyer with the -5s bolted up. The power line will just keep climbing instead of flating out : D

True that,

Got R33 N1's on my now old dinosaur things making 330kw, looking forward to better response plus lots more power

Nismo 600 purple tops? Prob still not big enough though.

[R31Nismoid]

Oh ye - I had a set of those LOL

600's would come close you'd think. Still one would like a bit of room.

[Ziller]

I have a built forged engine running standard cams with Tomei cam gears, standard head, air box and running -5s at around 20 psi on a safe tune.

The exhaust is 3.5" with a matrix 3.5" cat, this reduces down to a 3" exhaust about 600mm past the cat which includes two 3" elbows and a 3"muffler.

The cars at the workshop now and they are changing it to a full 3.5" system with a dyno run for minor adjustments to suit, its currently pulling 338Kws, this is a genuine back to back dyno run with an exhaust upgrade so it will be interesting to see what and if there is any differance in the power levels running the same psi and safe tune, results next week, Cheers.

To all the exhaust buffs.

Just picked the car up now with a full 3.5" exhaust, its gone from 338kws to 355kws and spools a lot earlier.

Happy Happy

Nice Nick, probably all in my head but my car with a 5" cat feels like it just comes on harder and earlier... Sounds poppier and louder anyway.

Thanks for letting us know. Thats a handy little increase and it confirms what is expected WRT power and spool. If it were me, next step would be to try a decat on the dyno to see if there's any potential for a better result with a bigger (5 inch?) cat.

Still haven't done anything (I know!), the car has sat unregistered all winter. Thinking of not fitting the Blitz injectors, but I'm having trouble finding Sard 700s and don't want to pay Just Jap over $1k for them.

Are these bolt in, with nothing else to be done as per the 700s?

Going to get some new discs and pads and it's time to decide where I get the work done...

[Moodles2]

800's will need new plugs, 700's have the right plug

have you looked at Deatschwerks injectors?

straight drop in (they're high flowed stockers)

That add says twin spray, but single hole - is that possible?

Shit they look excellent.

Any one had any experience with them? 750cc or 880cc is sweet. Given they are both $549, I'm tempted to go for the 880cc!

ID 1000's. Done!

[R31Nismoid]

800's will need new plugs, 700's have the right plug

Spray/nozzle is also different 700 to 800

I cant remember exactly which way it is, but one is twin and one is single.

Im fairly certain the 700s were the twins... (but please dont take that as 100%, cant remember when i looked @ mine )

[Beer Baron]

nah, the sard/denso 700s are single hole for sure. nothing wrong with that though, they have perfectly fine atomisation and spray patterns.

[R31Nismoid]

Do ya know if the 800s are different?

I remember there being a difference at the top, just not what

Yeah man. My 800's were a duel hole injector that needed new plugs (although I believe you can get single hole 800's, but I could be wrong), 700's are stock plugs and single hole.
