the thing i dont understand is why all honda turbo kits seem to be all or nothing, meaning lets slap on a big ole T04E to get some nice peak numbers. id rather have a 16G on there or something semi-small and just boost the fuck out of it. of course then youd probably have to go with sleeves and such but i dunno i guess i just dont understand the point of puttin a bigass turbo on a 1.6 and daily driving around on it. just my 2 cents.

 

keep in mind i understand the fact that many of the kits out there for hondas are based around near stock (high) compression and thus they supply a turbo designed to work at lower (safer) psi numbers.....but whatever if youre going to throw lower comp. pistons in there anyway why not go even lower than the usual 9:1 etc...............and then i guess there goes drivability again ahhh fuck it.

fuck hondas buy something stock turbo

 

Well there are also turbo's out liek the t3/t4(b) which HAVE hit full spool by 3100 and that is FULL spool, so 4 - 5 psi on that turbo @ 2500 which is a bit bigger than a 16g and comparable to an 18g has the SAME comparison as your 16g "id rather have a 16G on there or something semi-small " And can STILL flow high-end. I guess it is all preference. Either way, first gear will blaze open the tires

 

having 7.5:1 comrpession in my v6 i find running high boost is a fun thing, but one thing you have to keep in mind is that the efficiency of the compressor raelly needs to be suited to your engines cfm requirements and the exhaust side and tubine really needs to be matched to your engines displacement size in order to properly run the boost levels you want without chokeoff..

 

the way i look at it is you have a small 4 banger(b16/b1 that makes no power downlow what so ever...and you knew that when you bought the car. the only way to get the damn thing to move was to romp on it and rev to 6000+rpms. then you go ahead and throw a turbo on it(not good for the motor). if u put all small turbo on there thats spooling at 3000rpms(if not lower) your constantly puting strain on the motor even during daily driving becase the turbo is so small and spools extrememly easily even when its not intended or necessary. sure it feels cool but its aweful on a honda motor to always be in boost. your getting that awesome lowend/mid range power that was never there but at the expense of the motor life. it completely changes the characteristics of the motor. good pick up downlow but nothin up top. the opposite of that it was designed to do when it was built(headflow, cams, vtec, tec). also making it completely pointless to rev it to 8000rpm...also bad for the turbo because its always spinning at its max speed to try to keep up with the high revving motor.

NOW....if u put a bigger turbo on it, lets say something that spools around 4500-5000rpm your not going to be beating the shit out of your motor during daily driving. as long as its tuned right you wont lose any low end power compared to the stock all motor setup(maybe a little if u lower the compression). and when u want to get on it youll have to make that usual downshift that was expected on the all motor setup(higher rpm powerband). max torque is usually reached when the motor hits full boost which is still alot lower than the stock motor and max power will still climb to redline as intended.

its simple, if u want low end power dont get a 4 cylinder because it wasnt meant for that.

 

Sounds kind of Honda Specific to me. Here is a quote from edmunds.com
I have a NA 2.5 SOHC 8v Chrysler 4-banger at my house that will produce 136ft-lbs of torque at 2800rpm, with TBI and a manifold that makes the engine feel like its breathing through a straw. Boosted versions of this engine make insane amounts of torque for a 4cyl and with the long stroke of the 2.5 crank most of the power is made down low. Even the smaller 2.2L turbo 4cyl from Chrysler produces a good margin more torque than hp.

Then there are the 16v 2.2/2.5 which are even more insane as Levi pointed out. How many boosted Hondas do you see making 500+ ft-lbs on 16psi?

Well anyways I am just trying to make the point that what your saying is engine specific.

 

i was talking about big vs small turbos

 

My T3/T4 hybrid hits 20 psi of boost before 3000 rpm, but it only hits boost numbers like that if its WOT. You can use part of the pedal and not get anymore than 5 psi and this is on a 2.2 litre engine with 8 valves.
