Raise b18b1 redline
 

so guys, I am doing a little project before I go to college, a fun turbo build, here is what I am doing,

eagle rods with arp rod bolts

wiseco pistons with 81.5mm bore and 9.3:1 ratio

stock sleeves

kings rod and main journal bearings

arp head studs

then a nice turbo kit and looking for around 325whp-350whp

and I already have a b16 tranny with yonaka stage 3 clutch and act streetlite flywheel

what I want to know now is can I build the head with all brian crower parts and a stage 2 turbo cam, would it be safe to rev up to 8k rpms?
with a build head of course

With the correct valvtrain I would think so.

Re: Raise b18b1 redline
 

8000..probably but with the rocker arm design i personally wouldnt go over that and would feel more comfortable with like 7500-7800.

dont get a turbo cam if you want cams i'd say to go with the 403's.

if you are going to rev over 7500 you need to use a 22 tooth vtec water pump.

final parting words: you are going to hate having a straight b16 transmission over time. it will feel like it runs out of gearing especially up top. if possible i would recommend a gsr trans or at least a gsr 4th and 5th on the b16 1st thru 3rd gear

Re: Raise b18b1 redline
 

Balance the cost of all that against a vtec conversion. Then the sky is the limit and the low end is better too.

Re: Raise b18b1 redline
 

if I don't build the head can I raise the redline to 7500 with no problems? and I have been looking into a gsr transmission because the b16 is so short geared I feel like it tops out too fast as it is, but thanks for the input.

Re: Raise b18b1 redline
 

I was going to do a ls/vtec at first but then the head I wanted got sold so I decided a turbo build would be fun too, im trying to make it last a few years so I can get through college and maybe build the motor into a track monster!

Re: Raise b18b1 redline
 

valve springs and retainers are cheap and extra insurance, if you're upgrading cams they're almost a must. yes I wouldn't push a stock ls head past 7.5K on a daily basis or even at all.

Re: Raise b18b1 redline
 

TBH there is not much need for 8k redline. You can get plenty of power for the street with a turbo at stock revs.
