Hey guys and gals.
I'm a first time skyline owner and first time poster. I've recently purchased a very modified r33gtst. It's had extensive work done on the motor and impossible for me to list all the modifications but I'll try.
Fully forged rb25 only 20000kms old.
Cp pistons
Manley rods
Crack tested block machined and decked
Recon and hiflowed head
Massive garret turbo
Greddy forward facing plenum
Greddy fmic
750cc injectors
550lph fuel pump
3 1/2 " tbe
Microtech lt12s with a maffless tune with just over 300kw at on 18psi.
And that's only what I know about the car.
Now I'm having a couple of issues right after buying it. It blows a lot of smoke on full boost and there is a very strong non fuely almost chemical smell after you give it a bit of a boot. I've spoken to the guys that done a pre sale check on the car and they said that the motor is still brand new and has 160-165 psi on all 6 cold and hot.
Also it's first start of the day it runs very rough for about 5-6mintues then clears it's throat and all is happy again.
I used to own a heavily modified Subaru and know absolute jack poo about Nissans let alone a maffless tune. I have suspicion that something maybe wrong with the car with all the black smoke it passes the strong smell of something on full boost and these horrible cold starts. Despite having spoken to nearly everywhere the car has been worked on in the last 5 years and being assured it's fine by the likes of boost works jaustech southern performance and a few others. I still think something might be wrong. How much smoke is normal for this kind of turbo car? If anybody could shed some light on this or if anybody I'd a maffless tune guru please give me your 2cents. Any help is much aprectiated.
