GTM 1.5 need suggestions on build

martin82 · 02-04-2014, 03:44 PM

So no one is buying my gtm 1.5 kit, so this weekend going to get the car picked up.

Planning on the following:
1)Install CJ Motorsports RRP fuel starve fix
2) Radiator upgrade, either GTM 70mm plus shroud+spal fans, or other ideas?
3) Need clutch/flywheel ideas, this car is driven on the street and hpde trackdays/time attack competitions
4) Will need an upgraded CSC (stock one failed twice already), Z1 motorsports is testing out their new fix but I don't think I can wait for it to be released.
5) misc?

Huge thanks to Baer for the SC hook up!!

Call joe at zspeedperformance.
He has the clutch you need and upgraded cscs.

martin82 · 02-04-2014, 04:53 PM

thanks for the suggestion I will call him TWICE LOL

Radiator options also include CSF with upgraded fans/shroud but is a bit smaller on capacity versus the GTM one. Also a more OEM fit with the CSF as the extra space is towards the engine.
Clutch I cannot help, still on my OEM at 75k miles with my SC, partially being a little lazy with it but also it has lasted.

Besides that get it installed and properly tuned and hit the track. Only other thing I could suggest besides getting the system cooled is extracting the heat as much as possible.

I probably not bother with csf or mishimoto rads. Found out who makes the radiator for gtm and they are a legit company, but it is a single pass. I am talking to them see how much a double pass radiator would cost custom made.

The GTM radiator is the shizzle. I recommend the SPAL fan upgrade too. My water temps average between 170 and 180 with spirited driving and cooler weather. With HPDE's, I would look into twin 25 rows. I have twin 19's, and I truly feel it's not enough. It also might be worthwhile to look at their baffled oil pan. I have the Zspeed CSC and it's been good so far. Absolutely do not buy a JWT clutch or any organic clutch. I have the JWT and it's at it's limit. I feel the clutch get soft and the engagement is nearly to the floor when I'm beating on it. It could also be the fluid getting hot because the line runs near my PPE headers. Maybe get the SZ clutch and flywheel from Seb @ Specialty Z.

Did you already do the LSD? Also, what's been done for the brakes? Lastly, not sure if it's an option of if you'd need, but I use meth to cool my intake charge, it might help prevent heatsoak.

os giken all the way the green one twin disk is the **** for clutches.

martin82 · 02-05-2014, 01:07 PM

Car already has OS Giken LSD, I am on my 2nd broken rear driver's side axle, the CV joint keeps busting, you guys don't have that issue? Could be because majority of the tracks here are CW direction?

I will probably go with GTM 70mm rad and HO spal fans unless Ron Davis says I need a dual pass custom radiator.

Clutch, OS would be nice, need to find some sponsors for clutch!

I already have Baer's gauges, A/F gauge, temp gauge, boost gauge. Prob need to add oil pressure

Joepro · 02-05-2014, 01:18 PM

The giken sure is nice but holy expensive...rather change out the single disk a few times...of course I can do it myself

martin82 · 02-05-2014, 01:52 PM

Just spoke with Sam at GTM, have to request my rom tunes for uprev, he picked right up! Supposed to get them later today.

Car will be picked up on Friday night and it will be trailed to San Diego for the SC install.

snowsurfdirtx · 02-06-2014, 02:23 AM

Who's doing the install? I'm debating which clutch to go with too.. the OS Giken is pricey pricey but then again you don't skimp on boosted builds so why skimp now. I did talk with Joe@ZSpeed, and he had some great info. I'll be on the 92mm pulley till the weather warms up, and then I'll upgrade the clutch as well. Lemme know what you go with. Also, what pulley are you running and what are you shooting for number-wise?

martin82 · 02-06-2014, 08:33 PM

My friends over at Sportcar Motion in San Diego will trailer the car out and take care of the install. Will be running the 88mm pulley and also have the other pulley to run about 8psi forgot the size.

Have an issue trying to see if anyone knows, Is there any room to keep my Z1 34row oil cooler behind the intercooler 1.5 Stage, I want to add a 2nd 19" row. The car is a heavy track duty car so I need as most cooling as I can get thoughts/ideas? We are building a differential cooler as well.

Stole these from the net:

2nd oil cooler by fender liner:

And this is the same 34 row oil cooler I have and installed location:

You might need to move it in closer if you can fab a bracket. Mine are up front but my ICs are thicker.
