ok i want to purchase a greddy turbo kit for my sohc and want to make about 200 WHP daily (250 w/ a 50 shot for racing) anyway my set up will be as follows:

everything that comes with the kit (minus the blue box)
greddy intercooler
greddy type s BOV
HONDATA s200B
550's
custom 2.5 inch DP
2.5 or 3" exhaust
rods and pistons


NOW...for the concerns. ive heard of the greddy kits not pulling all the way to redline...im hoping with a 2.5" DP this wont happen and it will pull all the way to 7200. or should i get a 18g turbo from the DOHC kits? my other concern is which exhaust to go with...2.5"...or 3" thank you for the help.

 

my greddy kit runs out of steam up top... it just doesnt pull as hard near redline as it does at around 4k-6k.
I am thinking its just the efficiency of the small turbo. with a decent exhaust it can spool at like 3k but it heats up the air so much up top that you dont make as much power.

ive seen people using the dohc turbos and getting better results. ive "heard" it bolts right up to the sohc mani but i dont know personally.

turbo/NOS may be a little too much with stock sleeves dont you think?
isnt shooting 50shot w/ boost = 100 shot

 

bump...anyone else?

 

someone point him in the right direction... i saw this post just as i was leaving my house...

boost + juice on stock motor? good luck

 

well with 200whp as your goal that should be fairly easy to do with stock rods and pistons. The d16 rods are like freaken toothpick compared to b series rods so you can only make about 220whp MAX. pistons..... ringlands are going to go first at about 11psi. But if you want to make it a safer block...get the rods and pistons

you'll be perfectly fine with 2.5 exhust. going 3 inch exhust will not yeild only very small gains at peak power and at the same time negatively effect your entire lower rpm powerband. If you were making more power then yes going 3inch would be worth it.

WHY the 550? you should be fine with stock injectors at 200whp if your worried about it get some 310cc or 450.....but 550cc is overkilled.

The greddy 15G should pull nicely for a 1.6 sohc! It's made to be ideal and proportional to the displacement of the application/motor. It should pull nicely all the way to your stock redline. Slaping on the 18G will suck ***** an you will NOT even start spooling until about 3,300rpms and reach full spool at about 4,500-4,600rpms..... with a fairly stock motor setup and low boost not to mention stock redline----> it's simpley not worth it when you look at what streetable power you loose compared to the the little extra hp you might get above 6,000rpms.

if you get that tuned well you should make about 210whp at 10-11psi
Your stock sleeves be your limiting factor after the rods and pistons. Stock D16 sleeves should hold up to about 14psi.
