tridentt150v Posted April 6, 2011 Share Posted April 6, 2011 I had a hiflow at 250rwkw and it was sometimes pretty hard to drive. Made heaps of boost and came on hard way too early in the rev range. On wet days if you tried to accelerate in 4th from say 70 to 100km/h you'd get wheel spin all the time. Fun but a real PITA, you couldn't always count on controlling it. Not saying all hiflows are like this, but mine was. Stopping at uphill sets of traffic lights on wet days - just thinking about it used to make me break out in cold sweats. I'd plan my route to avoid having to go through them. I went to a 3076 with external gate and WMI at 300rwkw and its a totally better vehicle all round. Good reliable steady progressive power. Transformed the car, made it a damn sight easier to live with. So its not called lag, its called control to me!!! But buying and installing such a turbo takes more effort and $$$$ than one that bolts up to the std dumps etc. It really depends on your end goals and what you want to do with the car long term. Also - if you buy say a hypergear hiflow as an interim step - how easy would it be to resell later and get your $$$ back when you decide to up size??? Simple things like this can help make your build more progressive and easier on the bank account.

GeorgesR34 Posted April 6, 2011 Share Posted April 6, 2011 High flow would still be an option and there are high flows today capable of pumping out very decent numbers, how ever results of high flowed turbos varies depending on turbo work shops whom did it, since you are in UK sending it back n forward is not really practical. GT3076 is a good option, its not going to fit without much headaches and I'm aware of how expensive good mechanics are in UK. Other option is Hypergear atr43 "SS" series, which are very outstanding performers, they would also be the nettest turbo to install with every thing bolt up.

zoidbergmerc Posted April 6, 2011 Share Posted April 6, 2011 I dont know why people say 3076 is laggy. But then, comparing any turbo to a stock RB25 turbo its laggy. I thoroughly enjoy driving Lithiums 300kw 3076 .82 R33. The extra "lag" actually makes the car quite nice to drive. Your not constantly making boost without trying haha. But if you want it, its not far away! Plus.. the turbo spool noise is orgasmic. Everything this man said, plus 3076R + external wastegate & 2" screamer = epic symphony of orgasmic turbo spool and ear raping gate. Best ever.

rondofj Posted April 7, 2011 Share Posted April 7, 2011 Hi all, sorry for hijacking thread, just want opinions on hypergear atr43 G2 (260rwkw) and atr43 G3 (300rwkw) - anyone driven bothe setups?? What are the differences / opinion? Of course I know that the G2 would come on and die off earlier, BUT i would like to know what are they both like to drive on the street only with some spirited driving - its for a RB25DET NEO on a R34 and I'm deciding which one to get in the future - current mods - full exhaust, FMIC, Nistune, manual Boost controller @12psi, pod in box, NGKs gapped at 0.8mm. Tuner says that for 260rwkw all I need now is a Z32 and turbo - no injectors, dunno if thats true. Fuel pump Walbro GS3442 goin in on the weekend. cheers Ron Link to comment https://www.sau.com.au/forums/topic/359838-which-t3-turbos-do-fit-without-too-much-headache/page/2/#findComment-5749763 Share on other sites More sharing options...

Thus 370cc injectors will probably max out at 370hp = 277kw, which would probably result in something like 240rwkw.

rad100 Posted April 7, 2011 Share Posted April 7, 2011 If you get a 3076. Do not get the Nissan 6 bolt housing. It is restrictive and plain garbage. To fit a 3076 with the proper Garrett housing requires: Spacer plate ( so comp housing doesn't touch manifold) Extended studs Lines Dump pipe -all this comes with the kit and is not hard to fit up Only thing you will need to do is get a 4-3 inch reducer and make up a custom intake pipe It's well worth it And for response? I'm hitting 18-19psi by 3500 rpm. On the 3076 with .82 rear housing shit.. im making 20psi by ~5000rpm.. thats with e85, poncams and stempipe manifold Link to comment https://www.sau.com.au/forums/topic/359838-which-t3-turbos-do-fit-without-too-much-headache/page/2/#findComment-5750219 Share on other sites More sharing options...
rondofj Posted April 7, 2011 Share Posted April 7, 2011 is it a tyre fryer in spirited street driving? what is the kick like - sharp and punchy or gradual/ linear ??

rondofj Posted April 7, 2011 Share Posted April 7, 2011 take off / point to point, then yes for sure, if both stock then sti is quicker (cos of AWD??) but not by much, but i think the nissans respond much better to simple mods - even stage 1 mods - the modded sti wasnt all that quick - maybe it was farked, but u do have to rev the guts outa it to feel all the torque.. It was 99 model 4 door. I think EVOs respond better to mods than STis Link to comment https://www.sau.com.au/forums/topic/359838-which-t3-turbos-do-fit-without-too-much-headache/page/2/#findComment-5750258 Share on other sites More sharing options...

gotRICE? Posted April 7, 2011 Share Posted April 7, 2011 (edited) Not having VCT is costing you spool. Id expect 17psi by around 3500-3700rpm. On stock manifold, stock cams and 98. Internal gate too.
