264/272 or 272/272

[lanevo]

Hi

i have a 1995 evolution 3 same as your 2nd gen 4G63.

The way it is now it has:

exhaust (3inch)
Filter (k&n)
walbro fuel pump and fuel reg
profec b
FP3065
tial 44mm external wastegate
Ported evo3 manifold
HKS head gasket
HKS cams 264/272
adjustable cam gears
JE pistons
rods
ported head
injectors 800cc
Large bar and plate intercooler
computer Autronic

I had it on the dyno and got 305kw at the wheels on pump gas 98oct. (20psi)
0 timing on the cam gears

My question is:

I got a crack in my HKS cams (have to buy a new pair)

Should i upgrade to 272/272 or keep it at 264/272

It is a street car but i go to the drags in weekend.

my 264/272 set up wasnt laggy for street.
will the 272/272 make it bad for the street?

will re dyno when back together

Any help will be greatful.

What turbo does that have in it?

read his specs...fp3065

If you're staying with the fp3065 turbo it is best to stay with 264/272. 272/272 are for big turbos that spool later and are looking for maximum performance in the high rpms.

Oh must of skipped it sorry, anyway you have a pretty beefy turbo most people dont notice a difference with good turbo, usually its the stocker where they have issues on low rpm's

Other people make up for it with a tune anyway..

forgot to add

its 9:1 comp ratio

I'd go with the 272/272.

would i lose much low end power with 272/272


how much more lag will there be?
