Tu5J4 Approx Bhp?

[Zacky-94 7 2 Cars]

Was wondering if anyone knows a rough bhp figure of a tu5j4 with cat cams billet steel flywheel , induction kit 4-2-1 manifold ported and polished head? Cheers

120

 

 

which cams, and is it mapped to suit.

 

 

flywheel doesn't do jack to the power, neither do most induction kits, and most "porting and polishing" jobs make it worse.

Think there 708's mate not mapped no goes well tho!

Around 135 - 140 bhp realistically.

Thats fair enough sounds about right been told could get 160 with a remap but i didnt think that was true thats why i asked!

160bhp is entering ITB territory really. 150bhp is around the max for a remapped J4 with 708s...depending on the rolling road used

flywheel doesn't do jack to the power
