Need a little help from the pros in here. For those that have done it themselves or had a shop do their installs, could you guys give me an idea of the hours required for:

2018 C63s Sedan with downpipes, intake, mechanical bov already done.

Upgraded Turbos (PTG or Pure)
3 heat exchangers (CSF or other)
Meth Injection System (Weistech or other)
High pressure fuel pumps (Spool)
Low pressure fuel pump
Transmission extended pan (Weistech)
-transmission separate cooler
Spark Plug Change

I assume it’s one thing to do each of these one at a time and another to do it all at once. So, I’m considering doing it in 2 stages. The first being Turbos, heat exchangers, spark plugs and Meth, and then doing the fuel pumps, trans cooler and trans pan at a latter time.

Also anyone close to Indy you guys can recommend I’d be extremely open to referrals.

Thanks!!!

 

I would try to cluster similar jobs if I were you. Heat exchangers and divorced trans cooler are bumper off jobs and you would save hours by removing it only once. HPFP/spark plugs/ turbos also probably easier to do together.

Trans pan is a pretty easy DIY also if you want to save some $. You will end up doing a fluid flush during the change so you'll save a few hundred there.

 

Thanks! I originally planned to do it all at once, but the quote I just got from a local performance shop has me rethinking that. I’m hoping some folks here can help me figure out if they’re taking advantage or these things really take this long to install.

 

I'm sure they're calculating the hours based on whatever the time is for each as a single component change. I doubt they would reduce the time because bumper is already off as will save them time overall.

Spark plugs are also pretty straightforward and will save you a couple hours. Minimal tools are required. Does take a little effort though.

 

*****If the shop is familiar with the platform (M177), most of that work is relatively straight forward but the fuel pumps as well as meth injection will require significant amounts of time to do right, do the testing to insure no leaks that could burn your car to the ground, etc... The heat exchangers are bumper off, and require drain, refill, etc...of the coolant, and the turbos - even though they are right on top of the motor require significant time to remove the originals, make sure the new ones mate up with the downpipes, no leaks at the downpipe or at bottom of turbo and that there are no coolant or oil leaks once all of the O-rings are replaced of which there are quite a few, etc...

Spark plugs are easy enough, and so is the transmission, but fluids as well as new filter is like $180 on its own, and you *really* should change the motor oil after initial turbo break in, or even before if the oil was dirty. That just adds cost.

It's honestly a pretty big job overall and must be done with some planning. I'm gonna do an estimate of at *least* 15 hours do do everything right, including testing and tuning, shop parts and labor at $150 an hour so approx $2250 ish + an additional $750 ish for shop provided fluids like oil, coolant, trans fluid, and turbo install kits including the O-rings and special crush gaskets to insure a leak free seal, etc... The low pressure fuel pump requires some work to get out, and it's just grunt work that eats up time and requires care to not damage the harness nor the interior, etc.

Anyway, total ball park, and I have no clue where you are located or who is doing the work, nor what their experience is working on this platform of car. Definitely a learning curve with some of the aftermarket stuff for sure - especially fuel pump upgrades since they are aftermarket and AFR and EGT testing plus some tuning should be done to insure everything comes together nicely and is doing what it is purported to do without the ECM pulling an *** ton of timing due to detonation or pre-ignition at higher boost levels due to not enough fuel/meth or both, etc... I did all of the installation for my rig myself but had several hours of professional dyno tuning done afterwards to verify everything came together ok...







*****It sounds like a great project for sure though! Good luck whatever you decide to do.

 

What were you quoted by that shop to do it all?

Spark plugs on this car are a pretty straightforward task that you could do on your own if you are used to wrenching on your own cars. The ignition coils were a pain to remove but once I used another tool I had in my garage to help me get a better grip, they came off fine. You could save some money changing those out yourself.

 

Thank you so much!! This is exactly what I hoped for clarification on and exactly what I was thinking. I’ve always wrenched on my own cars, my business is just busy at the moment and I don’t have the time. The shop I was referencing below quoted roughly 49 hours for installation and then 16 hours dyno time….

I’ve since found a new shop and he is more in line with what you said. She’s gonna be a beast, can’t wait!!

Thanks again!!

 

They quoted 49 hours install and 16 hours dyno. I thought it was a typo so asked for clarification and he confirmed that it was correct. He did say I’d only pay for actual hours, but it’s hard to trust that now. Found a new ship though that I think will do a great job!
