Amazing. Job well done. Drive safe my friend.

You will walk out of this car entirely unnerved......have to experience it to really know what we are talking about here.

Below 3,000 rpms, it feels like "just another" powerful car. The clutch takes some getting used to. It is hard, about 5x that of my diesel Jeep, and is basically like an on / off switch. However, 50 meters and I got used to it. Its pretty driveable in traffic...light steering and slick gearshift helping. Cross 3,000 rpms and you know this is a special car. She pulls strong and clean, until 5,000 when all hell breaks loose. Literally. Few cars spin their wheels in 2nd / 3rd / (possibly) 4th gear at 5,000 rpms but this beast is one of them. I could see fellow BHPians R.P.M. & Rehaan shut their mouths and hang on for dear life. The thrust you get is forceful, aggressive, and one is literally shoved back into their seat. We were overtaking a VW Passat, and its driver thought someone is braking (hence the tyre noise). Hell, he was shocked to see tyres spinning, but the car accelerating in 3rd gear! Short-lived joy though, as we didn't have a chance to go all the way up to 9,500 (though I am so looking forward to it)!

One thing : This car is safe only in the hands of an ace; Jitu was super calm when working her through the revv range. He's obviously learnt how to tame the beast. Butttttttttttttttt in the wrong hands, this car is a widow-maker. Drive safe, Jitu. Congratulations. The mega-achievement was written all over your face.

Small detail I missed out in my driving post. When Jitu handed over the keys, I asked him if there were any special instructions. Pat came the reply "Keep her straight"

I've had a brief taste of this mad machine myself, and I'm hungry for more. Pulls like nobody's business.

The point is, this is what you need obviously. a discreet set of fender flares:

Fitting even 225's is a problem Ananth, and the OHC already has slightly flared fenders as a design feature! But, I was talking to him & after he gets his suspension, we'll try & fit 225's or more based on what we can get away with.

Another factor we'll need to figure out is it get some negative offset wheels or use spacers to put the wheels clear of the inner arch.

Correctomundo senor!

[pranavt]

So won't it hit the fender flares from the outside then?

First and foremost, congratulations on the first major milestone of the epic build. Was following it through various stages via various sources over the past years. Doing something of this magnitude in India isn't a joke, given the fact that it is a complete DIY project.

Thank you D.D.


That apart, I would like to know a few harmless details about the setup.

No, pure pump gas, i am doing a slight change in setup & tune now, with this i shall be able to extract more power at same boost at 17psi but with 93 octane fuel. & for Drag race the boost will be upped to 22 psi range on 97 octane fuel once i upgrade the fueling, thats the limit i am reaching for pump gas in forced induction.

All this kind of setup run an external wastegate, i am running 44 MM External W.G.

Cams are Honda OEM, Dual Valve springs,Titanium retainers & Forged Int/Exh valves.

Honda Cranks are very strong, Crank undergone balancing, nitriding after Sizing new bearings for Rod & Mains. Extensive modification to oil journals so that sufficient oil pressure is maintained for Rod bearings in high RPM high Boost application.

What driveshafts are these?

Yeah, my bad. External WG is the only way to go in these kinda setups.

You would be using a tubular manifold for the turbo. Is it a custom-sized and fabricated or an off-shelf item since B-series has massive aftermarket support compared to some other engines running on Indian cars.

Wow, thats a lot of work into the OEM crank. Where was this undertaken since its fairly high-precision stuff. Same question about the Darton sleeves- was the block sleeved here or abroad?

Thats quite conservative, but bang on for a daily drive pump gas setup IMO. No wonder fine tuning can yield substantial gains. What kinda numbers are you shooting for in your drag tune with 97-oct??

You had mentioned that you're running the injectors at 100% duty cycle. Do you plan to retain the same injectors past the 400whp mark. Will merely hiking fuel pressure help at that point?

One last thing (for now), , has the head/valves been worked on in any way even though these B-series heads flow pretty well from the factory. Also, is the block posted or a block brace used?

Edit-

@v1p3r- Jitu has mentioned in the previous post that the driveshafts are stock items.

I noticed. Stock Civic driveshafts or stock OHC driveshafts?

No chance of OHC driveshafts making it here dude.

Reason- the tranny is completely different, S21 box I think. Its hydraulically actuated, needs half shafts and AFAIK b-series driveshafts are equal length as opposed to d-series ones. Also, this particular tranny on Jitu's car has a factory LSD so any hope of d-series shafts being used is thrown out of the window.

The question is why? When d-series guys have found ways of swapping in the more robust, hydro b-series trannies with more gear options why would someone do the exact opposite and try using d-series shafts?

[v1p3r]

You're missing my point.

Jesus, those driveshafts must be pretty strong if they're holding over twice the whp they were designed to.

Pray, enlighten us mere mortals about that point.

Seriously, somehow Honda OEM driveshafts can hold crazy power levels. The mid-13s nitrous OHC from Bangalore is also running bone-stock driveshafts with close to 100 shot fired upon launch in first gear itself. Crazy!!! Gross over-engineering I guess...

[ananthkamath]

Its not gross over-engineering. Driveshafts in japanese cars have been known to hold over 3 or 4 times the torque that the stock engine puts out, PROVIDED street tires are used. DSMs and Evos running 1100 whp use the stock shafts, but a few drag launches on slicks will naturally break them. So I say its all dependent on the tires being used.

I was using Log type manifold which i bought off shelf.but now planning for something different.

The entire job was done here locally including Sleeving, i have some pics of install of entire process as i was involved with them during each & every step of process.

At 22 psi on 97 Octane Tune i wont be surprised if i come close to 430-450WHP.

I wont be going above 17psi on current setup, once i upgrade the fueling that includes 1000CC injectors,fuel rail,etc etc which comes in next month, i am not keen to run higher fuel pressure & strain everything.

Exclusive Head Job with Radius Valve Job

You dont need all that once block is sleeved.

Drive shafts are JDM with JDM S21 Tranny with OEM LSD which you will find in cars in Japan's Integra type R. that's one good thing i got.

Correctomundo senor!

I would go for negative offset rims as against spacers. At the kind of power levels the car is putting out, spacers MAY not work well, just my opinion.
