which turbo for a b18c2?

Hey guys

im in the planing process of turbocharging my dc2 integra (b18c2), and have no clue on which turbo 2 chose as i dont no any ppl personaly that have turbocharged a integra. my goal is to have a good quartermile time , and not exactly try and be king of the dyno.

ill b running stock internals so max boost will be 10psi. currently looking into the t28bb of the jap spec s15. What do you guys think of the t28 ,, or is it better to go for a t3? keeping in mind i dont want to be waiting for boost to kik in for 10 years.

thanx for the help guys

i dont know much about this stuff, but i see a few honda turbo inc a guy i know that use the t28, thats the most common one i know of and some with t3, but i havent heard many use them as much as i have heard t28 being used.

Get something bigger. A nice GT30 =)

depends, want, power wise, and how linear you want the power as well.
also driveability as well.

i had a t3/4 hybrid attached to my B18c..
full boost be 4500rpm to 8000rpm
t28 would be good but u will be limited top end and power wise..
Lag hurts but if its tuned poperly (my wasnt) will kik ass

either t28bb, great turbo, enough to pull up to 200kw.
or a gt28rs, better turbo, very good repsonse with up to 250kw
figures are atw

well im limited to the fact that i cant boost over 10psi, so i guess i want a turbo that will be in its most efficient point of that presure range. not much use in getting a massive turbo if its not gonna be boosted high?

im a bit confused here.... say i get a t28bb, at 10psi how much power will i get compared to a bigger turbo at same amount of psi. will the engine still be able to handel more kw's even tho its still at 10psi?

i used a GT2871 on my first setup on the stock internaled engine.....it had full boost at around 3500rpm and held strong with no boost spike.
if i had my time over again on the first setup i would most probably look into getting a GT3071r with a .86AR exhaust housing......i think these turbos would be well suited to the b18c and would make a shiet load of power on a low boost level.

If the goal is drag racing a gt30 or gt35r would be best and then just set up a two step. It will boost somewhere from 5000 - 6000rpm but it wont matter because the engine won't drop off boost. DL001 has a gt3037 on his stock b18c dcr2 that just got tuned by Dave today and made 204kw at 8.5 lbs. Kick ass setup.

You're asking a question without giving enough information.

Draw a picture of what you'd like your power curve to look like then the answers will come. No one knows how you drive your car other than you.

For example, I don't like to wring the neck of my motor every time I come out of a corner so I like to stay lower rpm in 3rd as opposed to high second. A larger turbo would be useless to me, so I opted for a smaller one in sacrifice of peak power.

If however you just like to go fast in a straight line, the bigger the better.

true..

however working out the size of the motor with the right turbo application is crucial considering the high compression of a b18c.

IMHO i think its best you consider internals as you are going to realise that boost will in the end cause wear and tear on a high compression vtec motor.

If its just a turbo your interested in i would recommend a GT28R turbo.

its a nice size for the application it spools up quite quick (mine spooled up full boost at 3200rpm and pulled to 6500 in my b18b2)

GT28R is better for street application and might not pull big numbers on the dyno as opposed to a T3/T4 turbo (due to the smaller sizging) but it will be a difference when it comes to tracking or dragging the car as boost is near instantaneous.

I believe a GT28R kicks off the fact that the bigger the better cause its a decent size seeing your only pushing it 10PSI (make sure you get a electronic boost controller as the bleep tap ones will spike) and it pulls you to close to redline.

MRJDM on these forums as well as chi at GPC have seen my teg turbo and the size and the application were right up there.

consider at least hi flowing your injectors (around $40 a injector) where they drill into your standard ones to make way for more fuel.

and make sure you change your oil to something more light duel to the turbo needing its bit in it as well.

Sparkies are a must and coolant as well.

if you need any other info or got questions feel free to ask

ok guys i have decided to go with the t28 tubo of a s15. as my mate is upgrading his s15turbo so i will get the t28 for cheap... i was just thinking about a decompression plate? any 1 know much about them? would i get more power with 10psi on high comp compared to 14psi on low comp?? and what kind of power figures should i be expecting with the t28 on 10psi?

thanx
