OK, I am planning on converting my 1991 Firebird 3.1L V6 to a L98...I see stock L98s run low 14s stock.....What should I run with just the HSR as th only mod?? Also, How does this compare to the Miniram???

Thanks

 

The HSR on an L98 with no other mods will not improve the ET substantially. The lack of torque will negate the added hp.

 

I agree. I think you would be better off upgrading the exhaust system first. Headers, 2 1/2 inch pipes into a 3 inch system and a good muffler. You will see good improvements right away.

Those manifold are for higher rpm. To take advantage of them you need a good exhaust system, cam and heads.

 

Yes - the HSR on top of a stock L98 is a waste of time and money.

The exhaust will open up the top end potential of the TPI system a little, and the car won't lose it's great torque which in my opinion makes it more fun to drive than a lot of faster cars.

 

Bigger Cam
Better Heads
Exhaust
High Stall TQ

These w/ the HSR will make her scream

(Doesn't have to be AFR's - there are plenty of budget heads w/ alittle bit of porting that flow decent for the $$$)

PS I think the V6's had 3.42 gears which would be ok, but a set of 3:73 and posi might be nice w/ that V8 - one wheel peel sucks!
