im getting a 2.8L gtr and need some help!!

**supramike** · 08-25-2011, 09:13 PM

Ok so I've been a supra owner for the past couple of years, but that will all change soon...I'm getting a 2.8l gtr skyline....the supra and skyline are my 2 top cars ever so I'm very happy to be or soon to be a gtr owner.
So this is what the gtr is running on
Oversize 2.8l
Ported head
87.5mm Forged pistons and rods
Tomei ajustable cam gears
Garrett gt35r ball bearing turbo
balanced engine
Stage 3 clutch
44mm tial wastegate

The next step for me would be a stand alone system like a aem ems but I'm really looking to get one used. Because with out it the car dosent run good at all..

Since I am new to the gtr world, I'm looking to get some feedback,help to find parts and some kingld of guidance to make this car run great with out loosing 2much throttle response for big hp.

So let me know what you guys think about this skyline setup

Does the car have a chipped ECU or does it already have an aftermarket ECU. I doubt that someone would have spent the money on a 2.8l kit and not take care of that too.

Was it built here or in Japan?

Does it actually have a stroker kit or is it just oversized pistons and the owner thinks that makes it a 2.8

Factory stroke crank

86mm =2568cc
86.5mm =2598cc
87mm =2628cc
87.5mm =2659cc

Thr car is running on chipped ecu ans is having alot of problems with maf and boost readings...
The guy ran out of budget on the build so he had to cut corners on the electronics in the end.

And yes everything done to the car was done here

Ok so I checked with the shop that built the engine this morning,they tell me its nowhere near a 2.8l stroker kit...all they did to the internals was forged it and shave and polish the cylinder walls to make it at most 2.7l but they told me to keep thinking it a 2.6 with 87.5mm pistons.....

The builders also told me all the car needs is a ems and change the air intake to a single cos he has single turbo setup but still 2 air intakes with 2 mafs....would it help if I switch the mafs the the 300zx ones...I heard they run better with that kind of setup
