turbo size ?

[86gixxer]

I am new to DSMs (as most could tell ) and just picked up two from my cousin. Ones a gsx and ones a GS. I am swapping everything from the GSX over to the GS (with the exception if the AWD drivetrain) and using a VCE.

My question is, since this will be a DD for when I cant ride my bike, whats a good turbo size for it? I am dumping the blown 14b and want a little more power. I am adding a TBE and wires and plugs (bigger wires) and probably a FPR and larger pump. I am replacing all seals and elimintating balance shafts while the motor is out. I am also going to do timing components and belt also along with the water pump.

Give me some ideas and thanks ahead of time.

Also if I am missing or incorrect on any of the supporting mods let me know.

I know the FWD trans doesnt have a VCE, I am using an AWD trans and have to put the VCE in to use it on the FWD car.

As far as a waste of time/money goes, you tell me where you can find a running 1st gen GSX for 500 bux. Hmm you cant. Like i stated, I am getting BOTH cars for 500 from my cousin and this is why I am swapping parts. He traded a pickup for these and then had a WP problem which turned into a head going bad (guy he let work on it was a dumbass who knows NOTHING about cars) on the 94. The GSX is complete and runs minus turbo being bad on it.

So all in all taking the time to swap it over isnt a waste of time at all. Also i could probably get close to what I paid for both cars out of the shell with complete suspension/driveline of the GSX.

For the price I am getting them at its worth it IMO

Alright, relax Chief. Don't let my post count fool you, I'm not new to this game, I'm speaking from experience.

Have you considered looking for an AWD shell and swapping the parts into that? AWD FTW!

yea, thats what i thought. Just like a step bigger turbo and supporting mods. I know from my honda days the 14b is an efficent turbo but not much over 10 psi. Anyways I will look into that.

whoah are you talking about a 14b on a honda or on a dsm. Because 10 psi is weak for a 14b on a dsm. Im running 13psi on my 14b right now with a boost leack and im not even scratching the surface of performance from this turbo.

Know your turbos before you post about them. The wastegate opens above 10psi.

DSM Dyno Challenge - 14b
DSM 1/4 Mile Times - 14b

+1 thank you 10psi is nothing for the 14b

really, see i guess its different between the cars then. We were using them til 10-12 psi and then having to swap to a 16g on the hondas (I never personally ran one but knew guys that did).

Hrmm kinda makes me think a rebuild of the 14b and an safc with an fmic would be suffice, be it I swap in bigger injectors and stuff??

I could see that being that Hondas(ie d series and b series) have a much high CR than our cars.

 

[86gixxer]

yea the guys I know were running them on f series motors with 8.8 CR but i guess they were playing battle of the turbo size evidentally.

If you use a SAFC, you'll need a logger to see what you are changing and it will only adjust fine up to 750cc injectors. The 14b is good for around 25psi and anything over 15psi you will need larger injectors and a bigger fuel pump to push the extra fuel needed.

Had I had a s2000 with an f20c I would have been happy with staying at the 11.1:1 CR. 8.8 seems redonkulous unless you planned on running 30+ psi.

You know that evo pistons are at 8.8 and the 2g is at 8.5. The 1g is even lower.

Im sorry....Im trying to figure out if this is a serious question.

But yes, I am quite familiar with the dynamics of my own engine. Thank you for the input.

Haha ok, I just wasn't sure if you knew that from your above post. It sounded like you were saying that 8.8 compression is crap and only for high psi applications. All cleared up though yes?

 

[86gixxer]

haha no they were on 90-93 honda accords. F22aX series 2.2L non vtec. 8.8 CR. The dsm manifold fit the motors with a little drilling of the mounting holes.

anyways, I will look into the logger and SAFC. Im sure the 14b will be sufficient then. The FMIC will help though Im sure.
