Advice needed

rupteur7000 · 05-28-2002, 08:33 AM

i will be going with a ludespeed Stage I w/ or w/o a front mount intercooler (not yet decided) sometime between now and the winter.

what i need advice on is:

- Should i get Borla headers, i got a good deal on the last gen, or should i just keep the stock ones?

thanks

Stay with stock. The Borla headers are NA headers and are not designed to work with a turbo. They just do not keep the exhaust velocity as high as the stock ones do.

That's not necessariy true.... The Borla gen 3 headers do in fact work with a RS-T. They do an excellent job or reducing EGT's and increasing spoolup times.

I had them on my RS-T (prior to going RS-TT then back to broken RS-T) and was getting 250 RPM's quicker spool and about 200 degrees cooler on the EGT's (probe is in the collector).

The question really should be will they work with the Ludespeed kit. I know that they work with the FAT kit.

Yes, they will work with the Ludespeed kit. The Ludespeed kit bolts straight to the stock header location, so any NA header will work.

I'd personally stay away from the Borla.

jewbaru- why is that?

Kaste ~~ How would the headers improve EGTs? The only reason I can think of would be around the fact that the headers were dissipating heat quicker than the stock ones.

Doesn't that mean they are just disapating heat (energy), basically wasting it, instead of pushing it all through the turbo?
How can headers keep the egt's down... they aren't changing the mixture, are they?

rupter, the reason Steve just stated is why I'd stay away from them. The Borla's don't really do a good job of keeping the heat energy in the gasses, which is bad when it comes to turbocharged cars.
