Have a b18C5 with 8.5:1 CR looking for 450-550 whp. Motor will wind up to 9000 RPM. I was thinking t3/to4e or t3/60-1 HIFI? Any suggestions please!

 

IM Arturbo, he can sell you exactly what you are looking for at a great price

 

60-1 .63 a/r HiFi or standard (4" inlet) T3/T4 will do it
GT-30 .63 a/r will also do it plus it will will also spool up quicker
Percision SC-63 will also get the job done

I can get a T3/T04B with 60-1 Hi-fi, A/R .63 stage 5 brand new . $550
IM or email me.

 

t3/60-1 should the trick. Get it in BB for even faster spool up time. Is this a street car or mostly track car? If it's mostly track and you dont care about the lag on the street go with t4/60-1 or maybe even a 62-1.

I have a 62-1 P trim, .72 A/R and it not too laggy on the street and I made 426whp on 21 psi with it, and there was more untapped power left.
