009's with 6152 turbo??

[87NAT]

I have a ta-60 turbo at the moment with 009's. Just took out my 9/11 converte(3400 stall) and put in a PTC 10''L/U 3000 stall. I felt my car was not pulling hard on the top end.(Valve springs are fine) !/8 mile times are fantastic but it seemed to lose steam to the 1/4 mark.

Still not impressed even after converter change.

My friends GN is down right now. His 6152 turbo is available to try on my car.
Questions are: Will I notice a big difference swapping to his turbo and if so will my 009's fuel it. I am running alky also.

I dont mind turning the wrenches because it wont cost my any $.

Please give me some thoughts on this.

yes, 43s and alky will work.

IMO, you would see a significant difference in power and times if you run the boost over 20psi. In other words, if the TE-60 was a 20 and the 6152 was a 20psi, the 6152 would make significantly more power. The 009s can safely support 510 fwhp before you would need to supplement them with the alky. Which means that at around 24-25psi you would be reaching the limits of what just the injectors can safely handle. Here is a compressor map of the 61mm wheel, which is the wheel used in the GT35R. This is taken directly from Garretts website.

And here is info on how to properly read a comp map.

Now, even tho the comp map tells alot, there are things that will dramatically affect the hp levels. These being, what compressor cover is used, what turbine housing is used, what size inlet piping is used, ambient conditions and pressure drop across the intercooler core. So basically, comp maps give you a general ball park of the flow potential of the wheel.

I would advise caution and really stay on top of your tune if wanting to run thes injectors and high boost levels over 22psi with the 6152. Just to give you an example, I ran those injectors with a TE-45 (63mm comp wheel) a long time ago on my old Limited. (circa '98) I was running 27psi of boost and eventually had to run 50psi of static fuel pressure with a Lubrant race chip that had 100% injector duty cycle to keep from blowing head gaskets. This was before 50#ers and alky kits existed. This combo was fast, but it was very lean and needed larger injectors very badly. It did run 120, but those passes were not clean and there were a few degrees of detonation.
The alky will help you push the turbo higher, but just be careful.

Hope this helps.

Thanks for the info.

I have always planned to get some 60# inj in the future. Its just that I have already laid out some cash for this new converter and trying the 6152 wont cost anything...unless I really like it in which case I will be ordering one.

My long term goals are the bigger inj but I just wanted to know if I can utilize what I have in the meantime to see if it makes a difference. I know I will just be using my "seat of the pants" dyno because I wont make another track trip for a while...hopefully I will "feel" the bigger turbo.
