Got another year til the car goes together but in the meantime im collecting parts. gonna be an rsx street car lookin to make max power on the turbo then detune for street use.. that bein said wondering about this turbo i wanta try to get the spool time down in the 4500rpm range so far ive got a sidewinder made by jesse from afi, jb vband in out 6266 .82ar hot side, now my past experiences with b's makes me think 11.5 compression and some stage 2 cams would prolly get me there, or changin the vtec crossover, wanting thoughts from everyone...





next question what size injectors should i be lookin at to max this turbo? would i be better off with conservative sized injectors and an alky kit since it wont be on kill mode all the time?

looking for ideas cus i havent started collecting parts for the motor itself yet and i wanta stay with a full k20 motor. gonna be running kpro thanks to marylands emissions laws

 

Go with 1000cc FIC or ID style injectors, and I wouldn't use an 11+:1 comp ratio, I would run something around < 10.0:1.

 

i figured maybe the 11.5:1 would speed up spool time and meth/alky would make up for bein able to use smaller injectors/ lost timing due to the high compression? when i was workin in the dsm world it seemed to work pretty well the shop evo was 32lb on stock turbo and motor on aem and stock injectors..... i see that u own a dsm if youve used both before, and it may be just an assumption on my part, but what kinda differences are there tunin link vs. kpro

 

anybody else got an opinion? or thoughts?

 

I have never used K-pro, Link is a lot more of a user friendly kinda thing, I know with a lot of honda tuning devices like hondata you need a license to tune with it, and a lot of them are just chips that you burn setups on to, not like dsmlink. But like I said, never used Kpro. Go with bigger injectors and just have them tune duty cycle and pulse width, that whay when you want to go for more power you have room to play with the injectors. And I would just stick with lower compression, less chance you have to pull timing and such and worry about detonation/pre ignition, and worry about running meth.

 

First off, what's the power goals and/or track goals with the car?

Second, don't bother with water/meth. It's just one more thing to go bad.

Third, you're not going to get a 2.0 liter K-Series to "spool up" by 4,500 RPM with the Precision 66 exhaust. You'll make some boost, sure, but expect it realistically to be a 5,500 RPM and higher car.

 

you don't need a license to tune s300 or k pro.

 

I know for the s200 you do, I was just saying, most honda tuning devices aren't as user friendly as DSMlink and such.

 

as he has a k series, he will likely use k-pro or aem. s200 isn't even available anymore.

 

mid 10's for compression. you start getting into the 11's for compression your really pushing the threshold of detonation and even with a good tuner things can go horribly wrong really quick. 6262 would be better suited for the streets. the 66 wheel is fo drag cars mainly. it wont be a suepr streetable turbo but wont be to bad either and like stated above expect to be a 5500+ car.

Go with stock type s cams or some skunk2 all motor cams. do NOT use stage 2 turbo cams if thats what you were refering to. Honda engines dont respond well to turbo cams they work better with stock cams than turbo cams. There is nothing wrong at all with kpro and its fully tunable on an RSX and doesnt require licnce or chips its a real-time ecu.

 

They are pretty user friendly now. Plug in the laptop and go. The S200 is so 6 years ago, lol.

No need to use cams on your setup, just get some stock TypeS cams. Cams like to destroy tensioners and on a street car that is absolutely no fun to deal with, either that or you get to pony up for the Hybrid ones lol.

Compression is a little high, while you can certainly deal with it you're going to be limiting yourself on the street. Higher comp isn't going to make the turbo spool immensely faster, a few hundred RPMs at absolute best and even then it's not likely.

If you want a 4500 car you're going to need something like a 5857. Even the 6262 won't spool that fast, let alone the 66. How much power are you looking to see from this thing with such an early spool?

 

Dude I was sayin that as an example, comparing honda tuning devices to DSM tuning devices.

 

lookin for as much as 750 for track but building the motor so upgraded turbo is possible when a trailer can be afforded, id like to run 400 on the street give or take, i know suspension wise these things dont like to hook on big power and theres no good cure, i built a hatch b4 strictly as a street car now im lookin to do something more race but on friday night take it out and make some mouths drop open more like a street rod kinda thing meets honda, take the wife to get ice cream and destroy some rubber, ill definately be usin kpro since its still gona be tagged here in MD aem doesnt pass emissions tests, the idea behind tryin to get it to spool sooner was so if i did take it out on the street i wasnt ringing that crap out of it constantly to play and gettin a power band in a more streetable range without bouncin top of rpm range, now as far as the cams ive got stock type s cams in it now, will the springs and retainers hold up and would it be worth it to put 1 over valves in it make it flow a lil more? my end goal will be 9's when it can be a dedicated track car, just figured building the motor the first time rather than after breakin stuff again and again makes sense since i have a year worth of time to gather parts, the hatch reached full spool at 5500 on a b16 but even with a 10k redline streetable it really wasnt, but i got a good deal on a brand new 6266 so thats where im startin with this one

 

You think you are going to reach 750hp on stock cams/springs/ and retainers. Sounds like this is going to be built off hopes and dreams. I hope you got pockets as deep as the grand canyon my man.

And your run-on sentance/paragraph gave me one hell of a headache.

 

mechanic here not an english teacher, and the whole point of the post was lookin for people that have seen good results with parts hopefully in turn speedin up spool time, not lookin for anything stock, just put the money where itd be most effective, and as far as grand canyon pockets, im in not rush the cash flows like the nile nice and steady

 

wouldnt be mentionin +1 valves if everything wasnt gettin upgraded

 

Seen a few 600hp k20a2/z3 all stock just slapped a turbo, injectors and fuel pump. I would def go with 10:1 CR. If you want to rev to 10k you need an a2 or modified s2k oil pump.
