Only one way to find out!

Worst case it comes off and I hate it and have to re-install. I've driven these stock before and I'm happy with what I've experienced. I'd rather have the money anyways to do other things that make it more of a drivers car. Might be an expensive mistake but it could also be re-purchased in the future.

I spent 12 years with a 1997 Integra-R as my weekend toy, so I understand your background.

The Harrop really makes this chassis/engine combo shine. I liked the N/A V8, but especially at high-elevation where I am at, the lack of torque started to frustrate me.

My best advice, given I installed a second-hand kit on my car, is to reference the installation manual and build a complete 'kit list', and bounce that off of the images out there (good search) of the entire kit contents. The handful of things that could easily be missed:
  • Check Valve
    Intercooler Install Grommet
    Misc. tube clamps
    Misc. fasteners

With that said, hopefully you have the OE items (injectors, manifold hose adapters, etc) that go back on the car.

Good luck.

Maybe. I don't know what audible noises the bypass valve makes when it opens/closes.

I tried a hard launch today and replicated the noise, it only lasted for about 1-2 minutes this time.

I'll do it again and record the audio.

I'm with everyone else here; I would reconsider if I were you.

I completely understand your thought process, but the linear curve that a harrop produces is so much smoother than others can offer and I think you'd have a lot of fun with it.

I'm sure very few have gone the removal route but anything I'll need to purchase to re-sell it as a complete kit that's hard to reuse?
If you do decide to sell the kit I know someone that would be interested.

Finally harrop boosted!

After a couple days of tire roasting I can say this thing is awesome! I've had a vf650 kit on my e93 for a year or so along with about every other after market part you can think of and decided I wanted a track ready supercharged e92 and street tire smoking e93. Put the vf650 on the e92 with all the other aftermarket goodies(brakes, suspension, diff, wheels, straight pipes) and got a harrop for my e93 b/c of the added weight of the vert I figured the low end torque would help it out.
Exactly as I expected! Harrop is a masterpiece of engineering and looks/feels like factory as opposed to the centuri feeling like an add on. With the top down there is a firetruck siren under the hood! The low end is outright nasty on the harrop and really shines on the street, sooooo much more fun. You can feel the HP difference on the top end but when stage 2 hits for the harrop its game over the for centuri not even close. The fit and finish on this unit and install is second to none. Bra-fucking-vo!!! No doubt a harrop is going on my e92 very soon!

Planning to add a Harrop to my car at some point in the future and curious who all is running a different differential with the Harrop? Any considerations with that in mind? Aiming for something with good street manners but also useful at the track, will likely grab a custom diff from driftflo. Car is DCT, also planning on full do88 cooling before the Harrop goes on.

For those wondering......the car is fast with the Harrop. Maybe a bit more punch than I was expecting in the midrange.

I finally gave it all the beans

Hi guys,
I was wondering if anyone had thoughts about running a catch can with their harrop s/c motor? I would expect it is worthwhile but I haven’t found much information about it. I guess it would be good preventative maintenance?
Thoughts?

Also Steve! Glad you are enjoying it! Are you going to keep the s/c after all?

I don't think so. For how I like to use the car and the things I'd like my money invested in it's just not anywhere close to the top of my list. And if I didn't already have it I can just about guarantee you that I'd never buy it.

The kit is wonderfully put together and you could easily pop the hood and it take a minute for people to realize that what they are looking at isn't OE.

I'll certainly drive the car around once it's off and figure out whether I'm making a huge mistake selling it before I actually let it go.

I will no longer be posting on this thread as I am tired of certain people and their negativity. There are existing customers out there that have Stage II, and those that are interested may give me a call should they be interested in upgrading. Merry Christmas and happy holidays everyone. Hoping 2020 is a much better year for all.

Hey Mike, sorry to hear that and apologies for some members who have been on the hate train as of lately. I know you've posted about your family/issues in the past few months and my condolences and I hope it gets better for you. If you never come back to the thread, totally understand and thanks for all the support you've provided to me and others over the last couple years. When I'm ready to buy a Harrop kit next year, I'll give you all a call and talk shop, thanks!

Guys, let's be honest with ourselves...it's almost a 7 year old platform, was never meant to be a 'super fast' car (more a fast and amazingly well rounded car as most BMW M cars are), and has always had issues making a huge amount of power unlike other BMW's with turbo setups (lookin at you 335i).

I think everyone needs to take a step back, look at what is out their right now, and just buy something that makes them happy. It's hard from a cost benefit analysis to continue to produce S65 performance parts when a ton of other models exist and are way easier to tune/upgrade (ANY new BMW).

And that's OK, all of you just need to come to terms with that and enjoy the shit out of your kit, whether that be a Harrop, Gintani, ESS, VF, Active, etc. If you want something to brag about, go purchase a used M5 or any used/new M3/M4, spend ~$2K and instantly have a ~525+ HP monster.

Come on man, not only has Mike posted about his issues in this thread specifically in the past, he's also posted about Stage II and how he is helping out customers who want to step up - simply giving him a call or a chat and he's responded.

It's the holidays, take a step back and just breathe man, if you want a Stage II just give Mike a call and I'm sure he can help set it up for you.

Thanks Mike, sorry to hear about the additional family trauma. Hope the community respects your privacy and focus on what really matters!

To everyone else, I'm preparing to install my Harrop kit, probably start sometime next week. Thinking 2 days should cover it. Any DIY install tips are appreciated but the instructions are very thorough.

As part of the install, I ordered a Turner oil catch can. Anyone have any experience getting one to fit? My car gets 10+ track days a year so I'd like to find a worthwhile solution.

DRLane let me know if you have any luck with the catch can. I have bought one but haven’t installed it yet. When I checked my breather tube seemed very clean on the inside after 12k km supercharged and 4 track days. I will probably still install it, but might see what you do first. Also I have bought a HARD Motorsport disk ventilation system that I need to try and fit...

Started the install this evening - Only made it through the injectors, and changed the spark plugs.

Noticed the injector boxes were all opened, safe to assume that was to record the ID numbers for tune? Anyone know if I need to save the boxes and respective ID numbers?

Probably put a few hours each day and take my time. Was going to document, but honestly the instructions are incredibly thorough albeit backwards because Australia...
