silva33 Posted November 23, 2005 Share Posted November 23, 2005 it looks like you have a bit more top end than me... ill have to see you at the next meet!! my knock is never over 20ish and injectors usually 85% and jump higher rarely Link to comment https://www.sau.com.au/forums/topic/95854-my-rebuild-and-what-ive-found-out/page/2/#findComment-1737267 Share on other sites More sharing options...
Abo Bob Posted November 23, 2005 Author Share Posted November 23, 2005 So you guys really rate the GCG hi-flow as the best option for the 34GTT? I have an auto as well and probably chasing 250rwkw for the time being. How much extra kw will this turbo give just by itself I'm currently on about 200 so I don't know. If it's a long way off, I might as well get a different turbo. <{POST_SNAPBACK}> We rate it as a good comprimise. An upgraded turbo needs supporting mods like injectors, fuel pump etc. to be used properly. Pick a power figure then pick a turbo to suit. You don't want 250rwkw with a 2835ProS because you are wasting the turbos top end and therefore introducing needless lag. But if you can get 250 with a GCG highflow without getting out of its efficiency zone then you have chosen the right turbo for your required power. (And saved yourself a big pile of money in the process:D) Link to comment https://www.sau.com.au/forums/topic/95854-my-rebuild-and-what-ive-found-out/page/2/#findComment-1737297 Share on other sites More sharing options...
Bass Junky Posted November 23, 2005 Share Posted November 23, 2005 I'm not even into the efficient range of the GCG. 14psi is quote low.

satanic Posted November 23, 2005 Share Posted November 23, 2005 Ok so if I was to go GCG hi-flow... what else do i need to do with the engine? Or is this going to be a direct plug and play (of course a re-tune is expected) Link to comment https://www.sau.com.au/forums/topic/95854-my-rebuild-and-what-ive-found-out/page/2/#findComment-1737340 Share on other sites More sharing options...
satanic Posted November 23, 2005 Share Posted November 23, 2005 And more importantly, will the GCG take me to 250? Link to comment https://www.sau.com.au/forums/topic/95854-my-rebuild-and-what-ive-found-out/page/2/#findComment-1737343 Share on other sites More sharing options...

Beeble Posted November 23, 2005 Share Posted November 23, 2005 (edited) Search!!! Since i searched this to death recently... : without cams most are getting 230-250rwkw, mostly 240-250, some are around 220-230 (and seem to have been a little disappointed) with cams up to 265 eg SK's cars I spent a lot of time trying to compare GCG hiflows Vs HKS GT-RS, but i can't find many power figures for the HKS item they seem fairly similar though...

Abo Bob Posted November 23, 2005 Author Share Posted November 23, 2005 All the information you guys need is already on here. For a GT-RS or GCG highflow you will need injectors, fuel pump, probably a fuel regulator, full exhaust, high flow panel filter or pod in a box, some sort of engine management and modification or replacement of the AFM to turbo pipe which will suck closed at this power level. A GT-RS is a slight step up from the GCG HF. People have achieved 300rwkw with cams. If you high flow an R33 turbo you will not get as much power as a highflow of the R34 turbo as the exhaust housing is bigger on the R34. An alternative is to put a VG30 rear housing on the R33 turbo. I've got 480cc Nismo injectors. I don't know/remember what Bass Junky has used. Also, did you go to Z32 AFM Bass?

mad34 Posted November 23, 2005 Share Posted November 23, 2005 i had my car dyno'd the other day as i had a ebc fitted to stop rich retard or boost cut or whatever it was. With stock computer and boosted to 10psi i only pulled 160rwkw. I have blitz lm fmic 3" exhaust filter. That seems a little low what do you guys think. Its and auto r34 by the way.

Robo's Posted November 23, 2005 Share Posted November 23, 2005 Bass,Id like to compare your car to mine as i pulled 244 rwkw in my R33 HKS 2535 on 14psi (no cams), on the Racepace dyno. It would be interesting to see how they compare! <{POST_SNAPBACK}> Can i race the winner, ive got a 2535 and only pushed 231rwkw.

mad34 Posted November 23, 2005 Share Posted November 23, 2005 thanks bass. was that with same mods as me? ie I/C exhaust? i have bought emanage ultimate and am waiting for an ignition signal adaptor to come so i can fit it. I wonder how much more power i get. How much did you get with computer?

Sydneykid Posted November 23, 2005 Share Posted November 23, 2005 SK's 265rwkw figure was recorded in Shootout mode which at 250rwkw reportedly gives about 10-15 rwkw higher figure. Quick clarificatin, we have been able to duplicate the 265 rwkw (+ or - a couple of rwkw) in non Shoot Out mode. Several times during winter with ambient temperatures in the mid teens and inlet (to the filter) temps just under 20 degrees. It is one of the reasons why I can confidently say that Shoot Out mode doesn't ALWAYS give higher power readings. Well, not on our dyno anyway. cheers Link to comment https://www.sau.com.au/forums/topic/95854-my-rebuild-and-what-ive-found-out/page/2/#findComment-1737808 Share on other sites More sharing options...
Bass Junky Posted November 23, 2005 Share Posted November 23, 2005 I was wondering how long it wopould take for SK to see this. Any further thoughts on my 250rwkw ceiling SK? 14psi, very conservative timing......

That's on Sydney Optimax. If I remember rightly Bullant (Ian) acheived similar with his R33GTST using a VG30 turbine housing. Using Elf TurboMax I have seen 310 rwkw. cheers Edited November 23, 2005 by Sydneykid Link to comment https://www.sau.com.au/forums/topic/95854-my-rebuild-and-what-ive-found-out/page/2/#findComment-1737825 Share on other sites More sharing options...
satanic Posted November 23, 2005 Share Posted November 23, 2005 OK so a GCG hi-flow would be good for up to about 250rwkw... after a decent tune. I'm assuming that the SAFCII won't be good enough for tuning purposes? So for all supporting mods: 1 x hi flo turbo or similiar 1 x new fuel pump 1 x adjustable fule reg 1 x new management system??? Would you guys reccomend getting new injectors or would the R34 stock injectors be good for 250rwkw?

Bass Junky Posted November 23, 2005 Share Posted November 23, 2005 Stock injectors are about done at 200.
