Jou930 Posted 20June, 2011 Report Share Posted 20June, 2011 Is it safe to have a 1.2 bar spring with a stock intercooler and wastegate? Link to comment Share on other sites More sharing options...
Guest vas930 Posted 20June, 2011 Report Share Posted 20June, 2011 A very bad idea. Link to comment Share on other sites More sharing options...
Chris-p Posted 21June, 2011 Report Share Posted 21June, 2011 I agree with Vas, you would be putting enormous strain on the engine and things will defnitely go wrong. Stick with what JNR356 suggested. K27 turbo upgrade, one bar wastegate spring and change the cams to something like SC cams. This is exactly what I did in mine and it was awesome. More than enough power to frighten the day lights out me. Cheers Chris Link to comment Share on other sites More sharing options...
Guest vas930 Posted 21June, 2011 Report Share Posted 21June, 2011 Even .8 Bar on a stock engine is more what I would run. Chris is spot on ,with some small changes these things can frighten the hell out of you. I dont want to sound repetitive, but I think you need to have a more complete plan. The whole thing must work together or you can end up with a lagy time bomb. Read more on the info I gave you, have something thats reliable and reduce the lag with the changes you make. Please take note of what I said on the fuel supply, if you increase the air, the fuel must also. If not KABLAMO ! You may also want to talk to Loui at Motion Automotive. He builds great turbo engines that last. Be warned, he is a no BS guy that tells it as it is, but a great bloke. Good luck. Vas. Link to comment Share on other sites More sharing options...
jnr356 Posted 21June, 2011 Report Share Posted 21June, 2011 stock fuel system can handle the above mentioned mods,although i'd check your warm-up reg is in good knick Link to comment Share on other sites More sharing options...
Jou930 Posted 22June, 2011 Author Report Share Posted 22June, 2011 Thanx guys... Can I remachine the cold air side housing on my stock turbo for a larger impeller, so I can gain quicker boost down low? I can't get out of 2nd gear anyway....

Guest vas930 Posted 22June, 2011 Report Share Posted 22June, 2011 I would just get a new turbo. Tech has come a long way in the last 30 years. Why cant you get out of 2nd gear? Link to comment Share on other sites More sharing options...

Guest vas930 Posted 23June, 2011 Report Share Posted 23June, 2011 Hey jnr, would you go with the older kkk style, or a new ball bearing type eg GT35 ect. Link to comment Share on other sites More sharing options...

You guys are champions!!!! I will buy the new Turbo K27 HFS, and do the cams. My mechanic has recommended me to a fantastic exhaust manufacturer, who will put together a 4" dual exhaust (In black), Schnell Headers with heat for those drives to Olinda, followed by a EVO cold air intake and a Tial Wastegate. Do I need to adjust the WUR and fuel? I am thinking these modifications should be enough power for street use. I don't drive the car much and generally not on open roads, hence in 2 nd gear all the time. Once the vehicle is complete, I will consider having a quick run on a track. Thank you Link to comment Share on other sites More sharing options...
jnr356 Posted 23June, 2011 Report Share Posted 23June, 2011 i prefer the kkk k27,good performance and reliability,relatively easy fit(important to me ,cause i despise butchery) tried, tested and proven imho but needs to have cams ,waste gate spring,performance exhaust system and preferably a slightly larger intercooler for the package to work Link to comment Share on other sites More sharing options...

Is the KKK K27 a bolt on unit? Who would be the cheapest and reliable supplier? I like the Kolkeln intercooler and have read all positive results. I thought about the intercooler down the track as I am told that the stock intercooler should be the last modification. What work is required for the fuel?

jnr356 Posted 23June, 2011 Report Share Posted 23June, 2011 i did about six 930's ,like that just over two years ago at my previous employer over an 18 month? period nearly one after another ,full engine builds plus extras(brakes g/boxes suspension)etc,etc different combo's,with some engine components(be wary ,some well known heat exchangers fell apart at the flanges rapidly)some of those had scary hp ,not to be driven in drizzle out of date with suppliers atm,been doing 901's,911's more recently Link to comment Share on other sites More sharing options...
Guest vas930 Posted 23June, 2011 Report Share Posted 23June, 2011 Great advice jnr. I also hope your mech is familiar with Porsches, If not, give Loui a call at Motion Automotive. Good turbo man. I also would be getting a good look at fuel pressure. These changes are starting to push the limits of a stock fuel set up.Please stay away from adjustable boost control,have it set at a safe level and be happy. Good Luck.
