Guys im looking into fitting and moding a GTM tuner kit to fit my RHD car. After speaking with George the right hand side downpipe looks to be the only thing that will need modifying to get it to fit.

I have read the FI forums for well over a year now and read threads on home TT installs. The last DIY install i read was the gtm kit, and it was installed with the motor in the car.

For people who have fitted there own TT kits would you take the time to buy an engine craine and pull the motor or just work on the kit while the motor is in the car?

Ive never pulled a VQ engine before and and would like to fit the kit with it in the car but i have been following JETPILOT's GTM TT install and Quadcam and Jet both said the install would be hard with out pulling the motor??

Im not sure what to do guys? Ill have the car off the road for 7-10 days that i can spend all day working on the car so i should have the time to pull the motor of fit the kit in the car?

Any help would be great!

 

Pulling the motor and trans together is the recommended way to make install the easiest. Actually, putting the car on a lift and dropping the motor and trans out the bottom may be the easiest method. Not sure if that is an option for you though.

To pull the pair out from the top, take the entire front off and come up a forward at the same time. Many more pieces need to be disassembled to do it this way though.

 

you almost have to pull the motor to be able to tq everything correctly. it will also frustrate you beyond belief so its just a better step all around. if not, you will end up blowing out gaskets due to bolts and nuts not being tqed to spec.


have fun and good luck!!

 

for the GTM kit, I would definately pull the motor!

You'll drive yourself nuts trying to get to everything. Even with the motor out, it is hard to get the right angle to torque all the fittings on the turbos. the turbos don't come clocked in right positions for either the compressor or turbine housings. it is recommended to get the turbos in the car before tighten down the housings to the center section. I think I'd shoot myself if I had to do that in the car!!!

 

Thats what i thought you were going to say! haha...

the next question is how hard is it to pull the motor?? In terms of hours of labour 3-4 Hours to get the motor out ?? or more ?? I would want to pull the motor and trans all together if possible and from the top using an engine hoist.

 

Do you have a lift? It took me about 2 hours on a lift.

 

HAHA yeah right! All ive got is a huge cabinet of hand tools and a few jacks and axle stands!

Yeah i lift would make things 100 times better!

 

Its always good to have friends with lifts..

 

pulling a stock motor should be pretty easy from the front. We took the LONG way to JEtPilot's motor a few months back. We took the wiring harness off of the motor / trans beofre pullign the motor. that added alot fo time. it is easier to just pull the wiring harness out of the passenger compartment and leave it attached to the motor. also, we got stuck trying to get his motor out because we left the 3" greddy downpipes attached to the motor. after alot of back and forth, we reinstalled the motor and then took the DPs off. then the motor came out if about 5 minutes!

 

I am a fan of leaving the motor in the car as much as possible, but I think you really should pull it for the GTM install. If you were doing a greddy TT, I'd say leave it in the car.

 

Why with the GTM kit do you think you should pull the motor where as with the Gready leave the motor in the car??

The GTM instructions are for fitting the kit with the motor still in place arn't they?

 

the greddy is barely installable in the car......the GTM kit has more to do and more fittings than the greddy, too plus the grinding of the motor mount (makes a big mess...watch out for flying aluminum shavings getting into the motor!)

Don't let me stop you........if you are set on doing the install in the car, go for it! that's what I did on my greddy a couple of year ago against everyone's advice. I don't regret it.

 

If i did it all over again i would pull the motor.I installed the Greddy kit with the motor in the car 2 years ago and it was a total pita to do.

I think myself and QuadCam just wanted to be stubborn and do it with the motor in the car when everyone said its to hard to do.

 

Quadcam you say about grinding the motor mounts? I'm only fitting the 28rs kit so from what I have read I do not need to modify the motor mounts or knotch the frame rails?

The reason for me not wanting to pull the motor out is to me pulling the motor out seams like a big job (read, to big for myself to do! ) I'll be fitting the kit in a twin garge which still limits me for space to work on the car.

There are local shops by me willing to fit this kit but have NO experence fitting or working on 350z. There a subaru specialist and seam to know what there doing but you guys no what were like with our pride and joy cars. I hate people working on it when I know I would take more care and do a better job if I had a lift and air tools!

 

The pax side motor mount need to be ground a decent amount for the GT28 compressors to fit. I have the GT28 RS also. I couldn't imagine doing the install with the motor in the car either.

 

im doing the greddy tt kit with the engine out but i drop the whole sub frame and struts...its my first 350 build

 

You can do it either way, when we install the kits in house we do the install with the motor in the car.

We have also had a few customers install the kit themselves with the motor on the car, in their garage, on jack stands.

It will definitely be easier to fit everything with the motor out of the car, I am not arguing that point, but it is not mandatory.

Just go with whichever method you feel more comfortable with.

Let me know if you have any questions.

I am very very happy with the fitment of the kit so far. The motor is in and we have the intake piping to install. We checked fitment by hanging some pipes without clapms and it looked like a very good. No doubt this is the best kit on the market in my opinion. The bar and plate intercooler is one of the best intercoolers I have ever seen. Very nice job by GTM!

 

Thanks Jet, we put a lot of hard work into our kits and appreciate your compliments!

I am sure you will be even more impressed with the kits performance
