Hi guys

I have an r33 Series 1.5 i recently converted it to manual as it was auto. now when it was auto i was running 10PSI fine car ran great now that i have converted it and replaced computer with the manual comp it will only do stock boost 7Psi i modified stock actuator to go staight to 7 psi so no in between. so when ever i try and boost it over the stock boost to like 8 9 or 10 psi its almost like i hit detination or something like fuel cut. it feels like a bad coil pack as i had that problem when i bought the car but fixed that with split fire coil packs

Also i have a stalling problems mainly in reverse revs just drop and don't come back any ideas??

i have PWR front mount

Split fire coil Packs

Iridium Plugs

lighten fly wheel

blah blah and more

car was dynoed and it made 245HP 183kw on stock boost

any ideas guys car runs fine untill you try and boost over stock boost

Sounds like the stock ECU have a fit @ too much load - try searching with "R&R", happens to just about everyone.

As for the stalling, do you have a ATMO BOV? IF so, thats the cause.

If not, you need to clean the AFM, TPS and so on... there are guides in the DIY section

was it making this power with the auto? when you do a conversion you up the rwhp by about 30 to 40 hp, i done one a few years back and went from 215 rwhp to 250 rwhp with just the conversion and a FMIC. as with all boost problems and no piggy back or after market ecu, sounds like you have hit R&R. need one of these to fix your problem. dunno about the reversing problem.

      The spray cans were in the "Kiln" room whilst I was preping the parts,  so probably around 2 hours to get them warmed up, the kiln room has 3 small ovens running at 100°c, 3 medium sized ovens running 100°c, and the large one I used running at 80°c, the room itself was about 28°c, I also spent a bit of time taping up the parts in the room as well, and by the time I was done I would assume that the parts were around that 28°c As for power, I expect a couple of Killerwasps up high would be achievable with the current mods, I'm still running the MZR 2.0 intake and throttle body, and there is a slight mismatch with the 2.0 intake (smaller) and 2.5 intake ports (larger) on the head, this intake is matched and specifically designed to fix this issue with the ports mismatch, the throttle body is also a couple of mm larger, OEM is 65mm, the Bosch is 68mm In the end it will look "prettier" than the molded plastic thing that is the OEM MZR 2.0 intake As for the LSD, it's the OEM Torsen which works fine for what I use the car for, plus, basically no maintenance apart from the occasional oil change

      Mate , I have the same issue right now with the exhaust noise , if you can tell me what your local guy did , I'll talk to my guys and see if they can do the same. Power is good but it just too loud when put it down.

      The other trick I've found with wrinkle black is to put the can in hot water for a bit to warm the paint up, and to pre-heat whatever you're painting. It'll be interesting to see if you pick up any power with the intake, following with interest. Got a proper lsd for this?
