He has always come through with very good and attentive customer service. My salesperson was Kenny, and I've dealt with Mark as well. Everyone I've dealt with at Stillen has been great to work with. Send them an email and they should take care of you.

Edit: so email address don't get posted. PM me is you want their contact email addresses.

 

I got mine used from a 370z and I've had no issues to date. The kit isn't a direct swap though. I messaged Stillen and they knew exactly what I needed for the swap. It was probably around $200-300 total in brackets and whatnot.

 

Thanks. I was able to get in touch with a salesperson. Hopefully should have a parts list and prices by today. She said she they had to go through the parts lists one by one to compare parts.

 

I've done a good amount of reading and want to make sure I've got this right.

Stillen SC Tuner Kit: $6495
34 row Oil cooler with thermostatic plate: $650.00
Frozenboost Intercooler Upgrade: $500.00 (which model is it and does anyone have a breakdown of the exact parts needed)
Level 10 Bulletproof Valve Body Upgrade: $998.00
EcuTek re-tune

I have a Stillen Tranny Cooler, EcuTek tune, Headers, RHFC, ARK CBE, ported lower plenum and 63MM TB's. I always read more flow is better in an FI system as it helps evacuate the cylinder better on the exhaust side allowing that cylinder to pull in fresh air faster. In FI environment the exhaust velocity should be high so having stock headers and cats should work against you I would think. I read a lot about people on here having to go back to stock cats, this makes no sense to me. I'll likely leave my exhaust alone unless I make poor power.
I plan to run 8PSI possibly forever, but at least for now. Should I upgrade to 725CC injectors right off the bat? Also are Injector Dynamics preferred injectors over Deatschwerks? Deatschwerks has 750CC for $599 on Z1 while Injector Dynamics has 725CC for $720.

Anyways have I missed anything major above as far as cost. Install will not be an issue as I have a lot of friends that are mechanics to help me.

 

Take a look at the Level 10 Torque Converter upgrade and then Fast Intentions Billet Flex Plate as well.

I suggest you go with test pipes, as HFC burn out a lot faster than the stock cats with the Stillen kit. I used to run stock cats and they blew out within 10k miles of install.

ID is much better than Deatschwerks. Do you have E85 in your area? If you can run flex fuel, it will help with temps and give you more power as well.

 

I am considering doing the Stillen SC on my 2015 Nismo Z and i've been reading that the 7AT trans don't hold up very well with boost. Some get away fine with just the trans cooler and others end up doing a heck of a lot more.

Im curious what is recommended trans work if i were to boost mine? I would rather be safe than sorry but I am also not looking to spend a fortune on the trans.

Thanks

 

It really depends on how hard you drive your car. I usually only hit 2.5psi MAX daily (3500-4000rpms), which is nothing honestly. Due to the design of the V3, the torque is very low with the stock 8psi pulley. If anything, people tend to blow their block instead of their trans. I didn't do the full transmission upgrade through Level 10, which is about 4k+ if I recall. I did the torque converter and the valve body through them and I've been running fine for over a year now. I just recently did the flex plate for peace of mind, but I don't think it's necessary.

 

Do you recall how much the torque converter and valve body was?

I dont plan on drag racing the thing but i want to enjoy it so getting on it, WOT, every now and then is probably what will happen. Granted it is not my daily driver so it wont see constant "abuse" if you want to call it.

Also are you running the trans cooler as well?

 

Yes, you definitely want a trans cooler as well as the oil cooler. I highly suggest getting the Frozenboost IC, as it's much larger than the stillen one.

I'd figure around $1200 in parts alone for the torque converter and valve body. You can give Level 10 a call and they can give you exact figures though.

 

Issue with replacing he torque converter are you have separate the trans from the motor which is very labor intensive. Valve body is not so much. Also what are your thoughts on injectors? Size and brand recommendations?

 

We like Injector Dynamics for upgraded injectors 725cc or 1000cc are both good.

 

I've been fine with the injectors that came with the kit. I'll be upgrading to ID1000 when I move to flex fuel.

 

Thanks guys. I'm going to do the Valve Body upgrade in the next few weeks then oil cooler. The it will be saving up for the kit and I may go with the Injector Dynamics 725cc off the bat.

 

The Boch EVO injectors are good also. I ran those 750's. Shawn I have every part number you need ( I started the frozen boost mod) parts are only like 250$

Thanks man. I will shoot you a PM.
