Question Q: Upgrade a Series I to a Series IV

Hi,

I found a used Series IV with 30k miles on it, and was wondering if its worth the 3k the seller is asking for it to upgrade my Series I in my 99 Saleen? I would like to keep it as close as to OEM Saleen as possible.

I did some searching here, and the Series I puts out about 280 HP, and the Series IV is around 370 HP...so its about an 90 HP gain?

Im running all stock for the exception of some BBK long tube headers. Would it be worth it. What is your thoughts?

I’ll sell you my steigemeyer ported series 4 with three pulley combinations (stock saleen/2.8/innovators west 10% overdrive, trick pony heat shield, mo saleen tensioner, lightning force heat exchanger, accufab TB, tunable induction cai, and walbro 255 fuel pump for $3k bud.

Blower had 18k stock miles. All mods less than 6k miles

Couple other goodies I’m not listing.
You will need injectors unless you can wait a couple weeks for me to take my 39lb uscar cobra injectors and adapters off my 4v.

Text me if interested and we can chat
