OMY31T

im acutally chasing 350rwkw+ with my auto(lose about 10% in power transfer) but for this build and tune, im hoping for 330rwkw with the stock plenum. as for ported head and cams, i have a set of tomei valve springs and lifters in my garage, waiting to see how the stock setup runs fisrt so i can give results, then i will be looking into some tomei poncams to go with the springs and lifters, and migh also be purchasing another head which as already been ported and polished to go on the car with an oversized head gasket. My engine has never been openend, still running factory headgasket etc etc. its only ever had a timing belt done. the thing which worried me, is oil pressure, which ive had issues with in the past. to the others who are worried about me damaging the engine - those squirts were for VIDEO purpose only, the car is in my garage not being driven until tuned, i think you misunderstood the excerise. 2ndly i know what pinging and detonation sounds like, this is the 8th performance car ive built, 2nd skyline, last was an rb20 r31. if i thought the engine was being damaged, i wouldnt have driven it. so please keep your comments to yourself. anyway, as said above, when the tune is done ill post from dyno results, its only going to be a "safe" tune im not pushing it to it limit just yet, im building an rb30 bottom end for this car, once it completed ill re-tune the car hopefully with the new head and push it out as best as it will go and then if it pops, its not a big issue. GT30 was sold along with everything else exhaust side to make way for the new setup

funnily enough the tune thats in it runs the car better than with my old setup, it has been tuned before(shit tuner shal remain un-named). rear tyres a Falken Zeix, they held 225rwkw fine, but they arent sufficient for the new setup. Also the HKS coilovers are extremely hard, even with the dampners set soft, the rear hardly moves which doesnt help.

short vid of a couple of half throttle squirts from about 40km/h in 2nd gear, im just pussy footing it around until its all completed and tuned i was backing off as it started to break traction lol only got 235's on the rear and lst traction around 10psi.

ok this is before with the GT30 lowmounted, and a return flow FMIC. and this is what it looks like now with the upgrades. ill give you a rough mods list. XSpower s/s highmount thats been HPC coated 44mm external gate plumbed back into the exhuast with 2" s/s pipe. T67-25G(obviously) 3" mandrel stainless exhuast with very minimal bends, only 1 muffler in the middle pipe and a hi flow cat. 800hp rated walbro fuel pump(not sure of model number) 700cc highflowed injectors splitfire coil packs z32 AFM blitz LM suspower pod XRacing bar and plate FMIC 3" in 3" out but only running 2.5" pipework to it. auto box, shift kit, with a Keys valve body( waiting for 3800 stally and transbrake to arrive) HKS hipermax II coilovers all round and some cusco adjustable bits to help it handle. all running on a Power FC. going to be tuned at Cosmic Performance in the next week or so after my turbosmart type 3 plumback bov arrives and the rest of my T clamps, as you can see some are missing on the inlet. cheers.

i have build pics, ill chuck some up 2 nite, also have a short vid of it coming on boost. its not booked in yet, i still have to get my bov plumbed in and waiting on a few more T- clamps to finish it off. hopefully it will be tuned next week. its not going to status anymore either. taking it 2 another guy, hes acutally got the import rights to KAMAK done a fair bit with these turbos. hes taking the car for 2-3 days and doing a full remap from scratch.

had a drive of my 33 today to see how it was for lag as ive gone bigger in intercooler and pipe size + .82 rear vs my old gt30 was a .63. All i can give is good results, turbo comes on nice, maybe a little to hard for my liking, but nothing some wider rear tread wont fix, felt great, and with all the mods and bigger rear, it seems to come on about 500rpm later, around the 3000rpm mark to a full 17psi. all i can say is, thanks to GTScotty for putting me onto simons thread, and thanks simon for taking the time out to post your build and results - very happy customer. im hoping for 330rwkw after the tune is done, but that might be a little over my head as atm i only have a 17psi spring in my wastegate, may need to go up a bit in boost.

i have just finished a build with one of these T67-25G turbos + supporting mods. its going in for a tune in the next week or so, will post results. Previous setup was a GT3076 internal gated on 17psi made 225rwkw also, my car is a manualised auto, so the power figures will be down a bit compared to a manual.

just looking for a run of the mill muffler, somthing with good flow, but not to noisy, i dont run one in the rear of my car at all atm, and now that ive done alot more mods, i dont want the attention. cheers. im located in vic, west gippsland.

hi guys, anyone around west gippsland area (drouin / warragul) got a car trailer i can borrow?? willing to throw some cash to whoever can do this. only need to get my R33 5km from my house to an exhaust shop so i can finish my rebuild. thanks.

housing is SOLD . thanks.

will ship anywhere in aus.

oil lines are SOLD. thanks. housing can go back up for sale, i havent heard from the guy in a few days, was supposed 2 ring friday, left plenty of msgs for him. ill drop the price to $150 firm with a pair of brand new gaskets(one for the 4 bolt and one for the t3 flange. i also have the compressor housing if anyone wants it, or ill throw it in with the rear housing for next to nothing. cheers.

very interested... i have a manualised auto box.. but no stally as yet, and im almost finished building what i hope to be a close to 400rwkw build. i do have a Z32 AFM but its in my car, not sure if i can part with it. ill see if i can come up with the cash.. if not, i might be willing to trade the afm for it, only prob im in vic. can u work out a postage cost to vic 3818. thanks.

hi guys, im chasing a splitter thats on the charcoal canister... its looks like a little diaphram type thing right up near the top of the canister. one line runs to it from the plenum and the other from the throttle body, then single line to the canister. also chasing the right angle breather for the cam cover, not the one with 2 outlets, just the single right angle. for rb25 btw. cheers.

hahaha nice vid man.

awsome time man. woohoo, my T67-25g turned up today, im gonna have fun building this weekend.

rear housing sold pending payment. someone buy the oil/waterline kit... will suit GT30's aswell. for those who dont know kinugawa is not a cheap chinese brand, it is made in japan, they are high quailty fittings, and high quality braided teflon lines. ill also throw in a brand new oil drain pipe + bolts + gasket if i get the price im after. cheers.

come on guys, surely someone wants this stuff... need it gone.. throw me a decent offer.

hi guys i have a .82 rear housing here to suit a GT35R - $200 ono - no reasonable off refused. Kinugawa braided line kit suit GT30 and GT35 on an rb20/25 - $70 - firm pickup from drouin vic, or will post at buyers expense. can get me via sms or pm on the forums 0416718140 thanks.

w00t all set for the T67, just waiting on some cash 2 morrow and it will be orderd. then its just a matter of a new dump/inlet and changing my intercooler piping a bit fun times ahead. thanks for this build thread man, it is a good read and hopefully i gan get the 350rwkw im aiming for this time round and it tuned at status also.

might make it... not sure if the car will be finished by then, but if it is, ill definatly be in for some dynoing and membership. will be cutting it close though, i dont think it will be tuned by then.

ill be in depending on the date, car is in my garage in bits being rebuilt would be good to get out with SAU anyway as im planning on joining the club sometime in the next month.
