What MOD next? TT or SC?

haddy98

I've decided on getting the GTM S/C kit. Hopefully I'll be getting it by next year. Still saving up some $$ though. Can't wait!! Are you planning in getting one?

Yup, doing research but I'm leaning more towards S/C over TT only because of cost and the S/C gives me the horsepower i'm looking for. Now its just of matter of preference GTM vs. Stillen. Any opinion is welcome...

Do you want to upgrade your tranny too? The S/C gets you close to the max HP/ TQ I'd be comfortable with on a standard tranny (auto or manual). TT gets you in the higher HP/TQ ranges but you will probably want to upgrade the tranny as well. The SC brings on power slower w less TQ so it's not nearly as hard on the car as a TT setup is. If your goal is to get well up in the HP range, skip the SC and go straight to TT.

Not planning on upgrading tranny.

Mr.Squeeze

No need to upgrade the tranny if its a manual 6 speed.All you would need is a clutch and CSC upgrade if you have a auto thats a different story.

To the OP what is your budget and power goal's ? A SC 370 with 400whp will hang and beat a lightly modded evo. But if one of your friends decides to go get a bigger turbo your going to need more.

Hmm, how much power those evos put on the ground with bigger turbo?

Mr.Squeeze

It all depends on witch Evo and turbo evo 8/9 can push more on stock blocks than the newer evo 10's.They can make 400-500whp depending on witch turbo they choose ,500whp would be pushing it on a stock block evo 8/9.I have a friend that has a evo 8 build motor 550whp low boost just for the street on a 35R turbo his high boost is 725whp.There isnt even a 370z that has even come close to making that much power.

My budget range is only up till the S/C kit. The turbo kit is out of my budget. Currently I'm on 316.5 whp with HKS exhaust and custom test pipes. My goal is to reach at least 400whp on my 370.

The Evo has been around forever though, we will get there. Also, I kinda disagree that a lightly modded evo will keep up with a 400whp 370z. Lightly modded is probably like stage 2, maybe 350whp. I've been in many evos at varying stages of power. Driven them stock, stage 2, and with a 30R and 450whp. I think It would be a nice race with a 30R evo8/9 and a SC 370z. Of course they can ramp up the boost, but they still have pretty bad lag from the 2.0. Hell they lag bad even with the miniature stock turbos.

If the GTM S/C claims 550 hp, wouldnt that add up to more than 400 whp on the car? just curious but I thought the conversion was roughly 15% from fly to wheels....

haddy98

I'm curious how the conversion is with the hp and whp. I know it's different for auto and manual transmission.

You are correct that drivetrain loss is somewhere between 15% - 17% on a manual transmission Z. The big part you are missing is the torque difference between a tt and sc Z. The hp numbers are similar but the sc makes power higher up in the rev range. TT makes power in the middle of the power band and makes more torque.

HP = (Torque x RPM) / 5252

In general torque is king in a drag race. HP comes in to play at top speeds. In short if both a tt Z and a sc Z have 550hp, the tt Z will have more torque and be faster in a straight line. The benefit to me of the sc is that the power curve resembles that of a stock Z and retains driveablity on a road coarse.
