turbocharging a prelude???

what would be a good turbo for a 2001 prelude???

None! Turboing an H series never holds up unless you only run 5-6 PSI. So if you want to only run 5-6, a T3/T4 is good.
Unless you want to build the engine first - Pistons, rods, and sleeves. Then you can run more. but that costs thousands on top of the price of a turbo kit.

id say that 6psi probably apllies to the B series too but some of that has to do with compression also, but you could run more with just the pistons and rods, sleeves might be overkill.

6 PSI? Maybe on a B18C5 which has 10.6:1 CR. You can run atleast 8 PSI on a C1. 12 PSI on a stock B1 which has 9.2:1, the rods can't handle more than 12 though.
With pistons and rods you could run 10 PSI on the H. More than that and the weak cylinder walls on an H series will start walking on you. But why go to the extent of pistons and rods to get 4 more PSI? Just get the sleeves and you could probably run 18 PSI with 8.5:1 compression.

you can do a turbo on the h22, and have it turn out pretty well. greddy makes a mild turbo kit that's pretty reliable. if you want more power but without the quality rep of the greddy, fmax makes a pretty good kit for the prelude. but yeah, h series in stock form aren't known to be friendly to high boost.

i guess im thinking of my dinky D16 :( . so the Bs have better cylinder walls then Hs?

Yeah D's can only handle 6 PSI also, but only because of the rods - not the cylinder walls. D's have better walls than H's!
Yes the B series is the best to turbo.

wow! thats cool to know. since im on the subject, if i had my rods balanced and shot peened and broke in some new piston rings do you think 35-50hp N20 fogger would be ok? ive been told it would but i realllly dont want to mess up my engine before the 240z is running (think hitchhiking)

D rods can handle 200 crank HP, so a 50 shot is no problem. So with that work you could probably handle 60, but why take that chance for only 10 more HP. What mods do you have now and how much HP do you think it has.

crane cam, springs and retainers, new piston rings, copper gaskets, cooler plugs, wires and intake.

What about exhaust, how free-flowing is that? And how much power do you think you are making now?

my exaust is still stock :(. I hope around 115hp?

Huh? You mean 115 to the wheels? The Z6 is one of the best D series and makes 125 stock on the crank.

yea im talkin about wheel hp

OK
If it were mine I would do a 50 shot on it no problem. Especially if you do that work you said you were going to do with the rods a rings.

cool, im looking at a nitrous express wet fogger

do any of younz have a turbo or know anyone with one?

h series motors have nikasil coated sleeve's, they are much stronger then d or b sleeves. thier problem is weak ring lands that sit way to high on the piston. the solution...getting forged pistons. well it doesnt work well because forged pistons score nikasil and you blow your motor, so you need to get pistons coated or you need it resleeved

as for b series motors my freind chris runs 10psi on a stock b16. most of the guys at hybrid dynamics (a shop around here) run about 8-14 on stock gsr's and one guys runs that on a type r and all with simple fmu's except chris who has the vafc fix.

and d series motors can hold it too, our boy jim ran 10 psi unintercooled with a greddy kit for months till he swapped in an h22, not to mention countless kids we meet up with every weekend from around the city that run 10psi+ on generally stock motors.

honda motors can handle the boost, they just like to be tuned right, plain and simple.

10 psi on a stock h22a is asking for trouble, as i know. I ran my car fine on 8psi with standard internals but as soon as i went up to 10psi it threw a rod out the block. This was whilst it was on a dyno getting tuned for the extra pounds.
If you want to make good cheap power out of a h22a i recomend you drop in a thicker head gasket and run no more than 8psi, it with 98ron fuel will run forever.
All the best :flash:

ok i just want to say one thing and if im wrong... then im wrong but not all h series suck for turbocharging. The H23A1 has a 9:8:1 compression ratio and is closed decked. doesnt that mean anything?
