OK, heres the set up so you guys can further help. Ive done plenty of re-search, but im still IFY on the set-up im attempting.

Set-UP
B-series GSR block sleeved 83mm (guessing 1.9L)
Ported B16 HEAD/Skunk1 Pro1 cams/Dual Springs/retainers/Edelbrock mani/
Tiltion Twin Disk Clutch
9:7:1 Compression, Eagle Rods.

Goal: 720WHP.

Turbo Choice: GT4202R
Manifold choice: AFI NEW BTM T4 twin scroll/ Dual Tial 44mm Wastegates.
Tuning with HONDATA.

1. Since i chose a faitly large turbo I'm afraid that my small 1.9L motor will not be able to spool the turbo as fast as i would like. You guys know any Pros or Cons to this??

2. Since spool will be a tad bit slow. I wanted to incorporate a 20 Shot of nitrous to help build the spool. (BUT) since im not familiar with nitrous, im not sure what kit would go best with a Turbo set up. Ex. wet kit? Dry Kit? and what kind of Nitrous control??

3. Whats boost control and dataloging system the best out right now???

4. As far as reving high, (seeing how im going to need it to spool the big turbo) what RPM would guys reccomend me to REV up to with my setup>>?? What additional parts can i get to make sure the motor/head hold up at those high RPM's. IF ANY.

5. I know i will need 1600CC injectors to get to my Horsepower goal, BUT this going to also be a streetable car that i will ocassionally take out on weekends, or to the local meet. But ive heard that 1600cc injectors are very unstable. They are rough on street driving. I was wondering if maybe i can get away on 1200cc for my goal, or if there is another injector out there that has proven otherwise>?? Ive heard of 1850's being more reliable, but i dont see how???

PLEASE ANY HELP WILL BE GREATLY APPRECIATED.

 

Can anybody help?

 

get rid of HONDATA get the Bosh injectors

 

ectune!!

 

The 1600 Bosch Injectors??

 

Ive heard of it, what adavntage does it have over Hondata???

 

If you're really looking for that much power, streetability isn't going to be your top priority. With something as larger as a 4202R, you wont have much fun driving on the street anyway.

As for the injectors, the Bosch 1600cc's will work nicely for you. I would be more concerned with your EMS. I personally wouldn't be all over Hondata...i would check into AEM or Motec at that point. Also, why did you decide on the GT4202R when there are other turbos that will suit your needs better...?

 

What would you reccomend for 720 WHP, that is fast spooling???


Why are you concerned witht he EMS. Ive seen plenty of Honda in the 800's with H-data??

 

evo guys are using HTA3586's and precision 6262's into the low 700 whp range

 

You're going to get so many different inputs on ways to do this, tons of guys are going fast with such different ways to skin the same cat.

For your HP goal, the 4202r is not neccesarry, however if you're looking for headroom and room to grow it is a good option. The 4088r or 4094r are great options for your goal of 700-750whp. With a properly paired divided manifold, such as the AFI BTM Mount, spool shouldn't really be a concern for you. I personally would stay away from the nitrous.

I'd replace the Eagle's with either Manley's/Pauter's. Don't be concerned with what you need to rev to, be concerned in choosing the right components to be able to take what the overall setup will need to be efficient. There's no reason to put additional strain on components by having a "Rev Goal".

For 700-750whp, you don't need 1600's. The Bosch 1000's at 60-65psi base pressure will get you to your HP goals, and be great on the street.

If I can give further insight, feel free to PM me.

 

Hmm i'll look into it.

 

Do you really think a small 10/20 shot would be dangerous???

Are the Manley or Pauters made of different material???The onlt reason i "had" a rev goal, was that the powerband would not be sufficient for a 42R.

Here in El Paso, The "race cars" have been maxing out there Precison/RC 1000CC injectors at abut 620/650WHP. Does Bosch make 1200CC injectors???

 

there are more features.

if i was you id definately ditch the 4202r,that turbo isnt going to be fun at all on the street,lots of lag then a bunch of tire smoke..plus that turbo is good for several hundred whp more then you are shooting for....if you already have hondata use it,it works fine from what ive seen even at 700+whp levels plus the s300 has a boost by gear feature that works well

 

A 20 shot of nitrous sounds like a waste. Either hit it or don't go through all the hassle. Hondata would definitly work great at that power level especially on a street car.

 

Cool, what turbo would you reccomend??

 

You dont think a 20shot would be a good spool helper or maybe if im loosing by a bit i can engage. Im not looking to make alot of power off the nitrous. I want to max my turbo as much as i can, using nitrous as second source.

you think its tht much of a hassle??
