Turbocharger discussion

[bonus12]

does the engine size (Liters) have anything to do with turbos? will the engine size affect the amount of psi the turbo is capable of?

the ct-26 adds about 30 horsepower to the supra. would the same turbo add a different amount of horsepower to lets say a 2.0 Liter? does the amount of cylinders matter?

if i am being unclear, lemme know. i am just curious about this.

Not only engine displacement, but RPMs, fuel used, and exhaust energy all play a roll in how a turbo opperates.

so would less displacement give for more psi, or less?

and isnt fuel usage alterable with a fuel pressure regulator?

i am thinking about getting a crx si for a DD. they are light and semi-quick.
do you think this 1.6L I4 is a good vehicle for a turbo? 108 HP stock, FWD.

thanks for the good help.

Displacement does not effect psi, it effects the response. The wastegate will control max pressure.

A Honda is a great daily driver. Cheap on fuel, and they rarely break. But being old, it will need maintenance.

so the displacement of the enigine will not affect boosting power... will a smaller motor respond quicker? i'm guessing yes.

does anyone know of a good turbo for a crx si? thanks guys.

It will respond quicker if you select a turbo that is the right size. a big T would push higher numbers but can be completely unusable on the street.

interesting. then i guess i am looking for something in the range of 6-10 psi. in a crx si, shouldnt this add about 50-60 hp? i heard somewhere that most turbos add 40-60% more hp.

any suggestions based on these preferences. you cant tell, but i very new with custom turbos. I'm just exploring this option, which looks great at this time.

This is a pretty good read when it comes to understanding what too look for in a turbo http://www.turbominivan.com/tech/turbo201.htm ,

I would also suggest going to Honda-tech since there is a great chance you will find your setup on there and what different size turbos did what.

Is there any comparison with the CT26 to the Garrett T25 Hybrid that was used on the Escort Cosworths?

 

[Nick M]

I would suggest a smallish Garrett GT for that little ass engine. And rebuild it first. High cylinder pressure is not what Honda had in mind.

Oh, Bonus12, is that CRX you're thinking of getting got a D16 engine in it, or a B16? I had a Rover 216 GTI with the D16A6 in it and was looking into a turbo conversion for it. Best thing i came up with was something like this: http://www.turbo-kits.com/crx_turbo_kits.html

thanks for the link. actually, i don't have the car yet, but it will probably have a stock motor. i dont know the code of it, though.

man when i hear honda i just :barf:.
maybe cuz my school is 80% honda owners.
but this is different. put some ketchup under the valve covers, they'll still run.
thats what some kids were doing at lunch break some time ago...

 

[TurboWarrior]

Hondas are good at 6PSI daily and a few higher. But 10 I don't think will last.

i would only use the crx as my DD. everything else is left up to the supra.

still, i think a turboed crx would be cool since they are so light.

I remember seeing a thread somewhere about an integra that used a modified manifold with a ct. Im not sure what it put down but it was definetly a "budget kit"

Depends on the motor, most B series (B18c,B17,B16) are good at 9psi with a t3/t4 57-60 trim. Ls motors, B18(non-vtec) can be safe at 12 psi.

how about the stock Si motor, D16A6?

I'm not sure, but I found this website http://www.turbod16.com/

Okay, it'll only be either the D16A6 engine (16v SOHC, 115bhp), or the B16A1 Engine (16v DOHC VTEC, 158bhp). By the the data table i'm looking at though, only the EUDM and JDM had the VTEC B16, so you'll more than likely have the D16A6 engine.

Dont worry though, cause there are two pre-turbocharging routes you can take to boost the power. Theres the D16Z6 cylinder head, which is almost identical to the A6, barring the introduction of VTEC, or theres the D16A8 & 9 Cylinder head that comes off the British Rover 216 & 416 GTI's. Thats a TwinCam head upgrade that never made it to the US - was strictly for European markets only. That'll take you from 113bhp to 130bhp instantly, even in stock trim with no exhaust, FIPK or AFPR mods.

Exhaust ports are the same config too, so you'd still be able to bolt on that turbo kit.
