75coupe

I did give the tuner a manual turbotech boost control bleed valve, and he tried that and it made boost control worse... I'll play with wastegate preload and boost control gain on the PFC and see what happens....

exhaust housing, wastegate and manifold flange area... Im interested to know what they have changed??

yep its on a dyno dynamics, Im keen to get home now and try the gain change

ok Im convinced time to move onto other things (of course checking the boost control gain first), like installing all of the CF Ive got coming, and rip through the masses of tyres Ive accumulated for destruction...

Yeah I want mine to come on boost like that... I'll try changing the gain and see, although its going to hard to tell the difference without hitting the dyno again, $300 for a tune touch-up yesterday doesnt exactly make me want to keep seeing improvements on the dyno printouts.

I agree, any ideas on what could help the response and get a flatter boost line? I expected it to ramp up smoothly and a tad steeper. and whats with the dip at 4800-5400rpm???

yep its the .6 housing for sure... here are the dyno charts, if anyone has any critic please comment... Havnt had a good drive of it yet, but it feels good and thats the main thing. and this time I got rmp, power & afr, easier to read.

Im fairly sure the 2835 all have the .63...

Well all the reading and research lead me to believe this was the best choice turbo for response vs power, the tuner believes the turbo is too small, but maybe he thinks Im chasing power beyond the 2835s range, I would of been happy with 275-285rwkw tbh, which I thought the turbo was well able to do, much less and it would be in gtrs rhelms really wouldnt it... I cant wait to post dyno sheets and see what people think... Im eager to see afr's myself

Finally got the car back in for another tune with adjustment made to the wastegate... now making 290rwkw, I'll post the dyno sheet once I pick them up... this time the dyno print should have rpm, boost & afr for a better overview...

heaps for sale still...

yep the r34 turbo will fit the std 33 manifold

can there be a diffuser over the indicator/parker LEDs so that you only see them when they are active??

I'll see if I can make some time for this...

I design and produce vinyl graphics for street, track & race cars, and not crappy off the shelf type stuff, this is full custom designed to suit the style of the car and owner... www.metal-ink.net generally though if your after cheap, it will look cheap... do it once do it right...

would be such an awesome xmas for me if they turn up before then.... fingers crossed....

well all that being said, go the HKS 2835 GT ProS... with full front facing plenum, FMIC, 3.5: all through exhaust no cat, 800cc + injectors on e85 tune... then just pay for tyres...

no fuel reg needed if upgrading injectors... 3071r will do more, do a search for it on here heaps of people have them.... and yeah stock manifold..

stock highflow would be cheaper to reach 240rwkw, hypergear do some good highflow stuff and can steer you with which one... 3071r will do it too... need an ecu, I dont recommend piggybacks... PoweFC is my recommendation but others will suggest nistune cause its cheaper and I hear does the job... injectors possibly, 740cc will be overkill, SR20 JDM injectors or 500cc, you could possibly get away with the stockers with a fuel pressure bump... I'll recommend new injectors though, get a new fuel pump as well of course... and then onto boost control... its starting to rack up huh.... do the installs yourself to save a heap though... then when your finished you get the mod bug and want more power... so plan ahead maybe...

oh an easy one, aerocatch ftw.... got em love em...

do you have a budget in mind? What your power goal?

isnt there also a temperature factor to take into account as hotter air moves faster so if you were to wrap the exhaust somewhat you get faster exit of exhaust gases or does that get cancellled out due to air density changes???

was the exhaust leak at teh manifold, turbo, dump or lower???? I wouldnt have thought an exhaust leak would do this..???

me too, update us...
