advise needed..
Hi all,
I have the following setup:
4g93T+Mivec top with HKS GT2835 Pro-S turbo. AR.48 on the hotside.
currently running internally gated, with 2.5" Downpipe.
Stock intake manifold and throttlebody, Evo9 intercooler,
Forged internals + ARP studs.
Currently running 4x560cc injectors from evo9, I have another set of 800cc injectors by sard ready to push this baby up.
Most of my friends and workshop are suggesting me to run it with external wastegate for efficiency and stable boost but I'll have to re-do a brand new manifold, and it also defeats the purpose of getting the Pro S version of the HKS2835 as they have another externally gated 2835.
The next thing im going to do would likely be:
1. Alu intake manifold + TB
2. Replace injectors and retune
2.5. downsize current injectors and add 4 more injectors and retune
the Last tune achieved about only 300whp @ 1bar, ran into 3 problems,
unable to hold boost
fuel press drop after 7k
TPS sensor fluctuating.
Right all this 3 problems has been resolved,
What should I do next? This is a daily driven car and im only getting about 6.4-7km/L with light footted driving on my Microtech LT10s. If possible I would want both power and alittle bit more fuel economy, maybe about >7.5km/L I'll be very happy
Would downsizing the injectors and add additional injectors improve on fuel economy for daily driver?
I would hope to bring this up to 1.5-2bar efficiently, can I get some advice from Sifus here?
Regards
Jeff
