Hi guys,

I have a 1st gen b16 (1989 jap motor )
It is currently tuned @ 12psi = 318whp & 218wtq.
t3/t4 to4e with a .63 a/r and a .50 intake.

Best 60' = 2.0 ( ONCE )
Best 1/4 mile = 13.2 @111mph with 60' foot of 2.1 ....
MT Slicks = 22x8x15 on gs-R hammer head rims....

I know the rims are heavy and now have a set of 11lbs rims to go on the slicks...

But is there a better slick option? Should I go with a smaller rim ?

Im going to be getting the front end all done ball joints etc... and a full alignment with corrner weights also going to be raising the boost to 15psi want to hit arround 350whp.

I'd really be happy with a 12.0-12.3 constant pass with this set-up.

Currently building another b16 bottom end for 450+/- whp pistons/rods/block guard etc.
Also going to be getting a full 3" downpipe, a ramhorn manifold and a gt35 Turbo.....

So for the current set-up I'd want to hit low constant 12's.... clearly my 60'foot is killing me.....
I've had a couple of other people drive the car and no one got a better 60' foot then 2.0....
if I can SQUEEZE A 1.7-1.8 60'FOOT the car should go mid 12's as is.....

Also car seems to have some blow bye.... I was thinking of getting a catch can and putting two ports on the valve cover.....

Thanks guys.........

P.S : Car is a eg coupe 1994 so I can't put 13" slicks on unless I do some mods....
Im thinking my slick/rim set-up was messed up hitting 2.0 60'foots I'll try the lighter rims but I don't think there gonna do the trick of taking off .3-.4 off my 60'foot I think my slicks could be wrong for this set-up " 22x8x15 M-T-"

 

exospeed 13" fits over 13" brakes.

 

i dont see a 13" wheel clearing 13" brakes unless they are wayyyyy spaced out. the exospeeds will clear gsr brakes.

at your current power, a 13 x 23 may benefit you better. BUT at your 450who goal, you will be better suited with the 24.5's.

play with the air pressure. spinning a little out of the hole isnt a bad thing.

my car ran its best time with a 1.68 short time. 9.98.

you need to play with rpm / tire pressure to find the sweet spot.

my old set up we started with 7700 and 8 psi. spun. then 7700 6.5 psi. big bog.
8500 with 8 psi, bog. 8500 with 6.5 bog. but could do better.
sweet spot was 8800 and 6.5 psi.
