currently I have a stock L98 with an exhaust and runners being the only mods, but want more power up top than what my TPI allows, so what would I need to buy in order to run this intake? I plan to do headers, and cam soon so I'm just wondering what fuel rails, injectors, etc. do I need to change, thanks in advance guys

before someone replies and throws this at you..all the info needed for what to do and tricks of installing the hsr is found with a simple search.

look up "my hsr swap" and you will find a thread by a well known member on here that goes over his entire swap and the parts he used to make it work.

use holley fuel rails for the hsr
reuse throttle body or upgrade to 52-58mm
buy vacumm fittings
and change the water neck to a more standard sbc angle and change the upper rad hose...i got away with keeping the tpi rad hose and slide it over the waterneck with another buddy using some wd40..and lots of elbow grease to push it on lol

also recommend using the kirban fuel pressure regulator to start with on the fuel rail.. the holley ones are garbage out of the box.and have fuel lines made to reach the rails.

the swap is very easy from there providing you have everything there to do the job.intake gaskets..basic tools it wont take long and easily done in half a day.well worth it if you plan on modding more than this in the future.

 

You'll make a bit more peak power. And you will lose some bottom end (not much really). However it will pull EASILY above 5000rpm. When TPI says its time to stop playing the HSR is just beginning to wake up with the right cam.

A vortec head/HSR setup with a hot-cam should make 300rwhp easy. Its basically the same setup as a hot-cammed LT1 which can make anywhere from 320rwhp to some freaks as high as 350rwhp. As long as you have the supporting mods though. Long Tubes are essential to make the higher HP numbers. So is a good cold air intake.

I was happy with my HSR'd L98.

HSR
Lingenfelter 211/219 cam (LPE74211)
Fresh valve job on L98 heads
Hooker 2055 headers
SLP 2otL cat-back.
