I have the ls1/6 rails with brackets and skinny ls1 injectors. Im just not sure if i can tighten everything down then instal the intake in the car?

You can't use the LS1/6 style fuel rails with the 102. The 90/92 intake will accept them but not the 102.

The only way you can use the LS1/6 style injectors with the 102 intake is to use the FAST 102 rails with the LS1/6 adapter brackets and appropriate O-rings.

i have all the correct parts. Im just asking if i can bolt everything up(rails and injectors on the intake) then put the intake in the car ??

I had one and sold it and went with a 92. For what I'm doing and the extra stuff I had to get for the 102 I decided to go with the 92.

^ 146032 Is the correct FAST LS1/102 Rail kit p/n. The other is a Gen IV number. The mount locations are off and TR has yet to update the p/n on their site.

146032 = LS1 injectors
146033 = LS2 injectors
146027 = LS3/LS7 injectors
146029 = LSXRT for OEM truck injectors & LS2 injectors
146020-kit = OEM style (LS2/LS3 rails) with LS7 injectors, injector cups
146021-kit = OEM style (LS2/LS3 rails) with LS1 injectors, fuel rail spacers

Ive installed a few of these.....

^ The wrong kit was sent to me. That's how I figured it out. But there's prolly a couple different p/n's for combos.. So we may be splitting hairs here. And I'm not sure what the poster above was referring to, just trying to help a little before someone makes the same mistake I did.

p/n 146032 =

There is really no reason to not know what you need because of this......

^ I just went off Thunder Racing's site for the rail kit I needed. They had to wrong p/n listed ergo I got the wrong kit. I trusted their site and still do.

maybe this question has already been answered and it so sorry.

If you use the LS2 90mm TB on this intake do you need an adapter plate?

LilJayV10

You can but apparently it can cause some turbulence issues. V max makes a ring that fits inside the intake to help smooth the transition out.

im have stock LS3 injectors and a stock LS3 fuel rail with the FAST spacer kit. getting ready to assemble the long block now.

also, what MAF are you guys using?

bayer-z28

iTrader: (14)

^ No MAF here.

It runs fine without the VMAX ring. I have run the LS2 throttle body on many vehicles with the FAST 102, including my own truck! (see avatar pic)

How do you think the the VMAX ring removes turbulance? It simply moves the step back farther in the plenum? There is no radius or bellmouth to help smooth the transition, its just hits an edge farther back.

what are most of you guys using for a bellow for the 102 to 85 MAF?

you should be able to use a 4" silicone coupler since the inside diameter is very close.. maybe some slight stretching over the intake but mine fit fine over the 92mm NW tb and 85mm GM Maf
