hi guys,

i just had an intercooler and electronic boost controller installed on my r33 this week and on friday she went on the dyno to get the mixtures right at the boost setting.

So far the one and only boost setting (atm) is 8psi and the car made 215HP at the wheels. However, i arrived a little later :Oops: ,and they did another power run and we got 210.4 HP. I was happy at this result as it is relatively low boost on an AUTO R33 (93 model) Gts25t.

I will be going back soon and we will boost it to around 10-11psi as that would be the max i would probably want to go with stock turbo and see if i can get around 230HP. Then take her to WSID :aroused:

The mods on her are:

- Greddy v-spl intercooler kit

- blitz dual sbc spec s

- k&n pod filter (need to box it up so it doesnt such hot air)

- custom 3.5 inch exhaust with 4inch dump pipe with a twin 3inch hi flow cat setup

the cosmetic add ons are side skirts and rear pods, GTR front bar, lowered kmac springs, 18inch rims and my boom boom system :)

my dyno graph had a little dip in it at around 150kph but was overall was a fairly good curve. What you guys think?

sorry, i should also add that me mechanic said that the drop was due to a stutter and suggested that i get the spitfire coilpack to fix the probelm for good. However i probably jsut do the easy thing and gap the sparkies to 0.8mm as its still at the standard gap.

Go to 0.8mm, you could run 1.2bar=16psi for short runs with the mods you have.  I was doing that with my stock turbo [not ceramic].  Is the ecu still std???, 180km limiter etc?

yeh still a stock ecu

twin 3" hi flow cat set up, i thought it would have been just as good to get a 3 or 3.5" turbo back exhaust with a single hi flo cat...

perhaps, but the guy that did the exhaust did the same system for a 32 GTR and the results were fantastic, so he did the same system to mine and i was very happy with the end product.

Yeah that dip will be at about 5000rpm where the stock computer dumps in extra fuel you would see it if you had AFR plotted on the printout.

It just gets bigger when you up the boost more. Mine is running 10psi. This run was in 3rd gear.

Speaking of boost, Don't try more than about 10-11psi on a stock ceramic RB25 turbo unless you want an excuse to hi-flo it.

Hey mate i have the exact same car i have a blitz front mount ,sbc id 3, 3.5inch exst and a k&n fillter at first i had a apexi safc 2 as well which was pushing 169 rwkw at 11 psi (I still have the safc 2 if interested) then i upgraded that to a uni chip computer now it has 200rwkw at 9.5 psi i have been told i need some new coil packs and injectors before i up the boost cause it can't handle the power but for an auto it goes alright dont get a blow off valve it made mine run like crap idling up and down. i could of put the $500 from the blow of value towards some injectors !!

Yeh i am keeping the standard bov as i dont see any need to change it unless its leaking (which it isn't)

thats an impressive power output you have at that boost level, but i didnt think that there were ecu's from uni chip for the r33...guess i was wrong. How is the gearbox hadnling the power, are the gear changes any different from before the uni chip?

PM sent about the safc II.

All stock GTS skyline turbos are ceramic(turbine). From the R32 to the R34. The series 2 33's have a composite compressor aswell as a ceramic turbine and give the best response by far but are prone to breaking blades.

      Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.
