40k for a 700 whp turbo brz? Pics inside

I bought a 2017 brz new from the dealer several years ago with the intention of doing a turbo build when I finally finished schooling and got my first big boy job.

It finally happened about two years ago. I got in contact with a reputable local shop and asked them to do a build for about 400 whp with a budget of 20k.

It has taken legit almost 1.5 years from then for them to almost have the car done (still not done). So the initial plan was going to be a closed deck IAG engine, my heads, turbo kit, tune, and fuel system capable of e85. They did that plus a lot of custom fabrication and added a gigantic precision 6870 turbo.

The car made 480 whp on the dyno yesterday without turning up the boost. It had a misfire and sounds like it blew a valve spring.

They gave me a new invoice for the work done so far. In total so far I will have given them about 34k. They have gone way over budget but they did do a lot of custom work and the car is pretty bad ass. I’m pissed that they didn’t ask me before going overboard like this, but I am excited to own this car. It is something truly special. They think that it will be another 3k or so to take my heads off diagnose and fix the problem.

Does almost 40k sound reasonable for a completely custom build capable of over 700 whp or are they using me as their personal bank?

I’ve never done a custom build like this so I have no barometer for how much this is supposed to cost.

I’d really appreciate any help or advice.

There is some miscommunication here from either the shop, you, or both. What did the build so far entail? Did it include any valvetrain work or anything in the heads? Did the shop state that the car should run 480hp on the valvetrain you have? or did they basically say, in so many ways, that anything can happen and you are responsible for additional costs to anything breaking?

Also, where exactly are you getting 700hp from? How can the car make 700hp when it can't even run on 480?

well all i can say is that 700 on this car is crazy insane i would say that 40k for what they have done is a little far fetch since you can get ahold of a custom block from Crawford for 6 and build from there good luck with this cant wait to see the YouTube videos and pics of this beast

I told them I wanted to make around 400 whp but wanted to build for the future in case I wanted more later on (I meant more like 500 not 700+).

They did not replace anything in the heads. They thought that the heads could take the power. The stock heads are really strong but I guess not strong enough. Anyway, the heads are being swapped for a ported and polished head with gsc valve train.

Any of you have a place I can stay at when my wife kicks me out? The car is kind of small.

For sure. I’ll update this thread if it ever materializes.

As for the Crawford block and building from there, this is the block I went with (with the bigger studs):

Yeah - it's playing the role of a fuse, lol.

Yup, 7+ trans in less than a year, I wouldn’t consider a reliable proof of concept either lol.

I also think it's way over spent
I wouldnt spend over 15K

I think there's two issues, here.

One is, did the shop do work you didn't authorize? Because if I agreed to a $10K build and they tried to deliver it two years later with a $40K bill I'd leave their shop and drive straight to a lawyer's office. In fact, I've never had a performance shop change an agreed-on price by more than a couple percentage points in overall price (IE, extra $200 on top of a $18K invoice) for any work I've had done.

Two is, is $40K for a 400 HP, 700 HP "possible" build*, reasonable? Well, anything's reasonable if you think it's reasonable. A 700 horsepower air-cooled Porsche build would be way, WAY more than $40K. OTOH a 700HP Mustang would be quite a bit less than that. The FA20 isn't a strong platform to build big power on, so - maybe? What's the cost of other 700HP FA20 builds? Personally I wouldn't aim for another over 300wHP if I wanted to stick with a FA20 engine.


* 700 HP possible build is, in this context, worthless nonsense words. If it's running 620HP on your "street" tune and 700HP on the "track" tune, that's a 700HP build. Non-running at 480HP "built for" 700 HP is worth nothing. You're looking at paying $40K for a 480wHP dyno queen.

this popped up in my news feed the other day

https://www.reddit.com/r/ft86/commen..._am_i_getting/

it's funny to read this thread, and then read that one. different people, exact same comments.

if one were so inclined, they could make a bingo card out of the 2 threads, and have a fun little game of catchphrases.

Op still hasn't posted the invoice and parts list... :/

[soundman98]

i'm wondering if there is even a compiled invoice/parts list.

sorta sounds like the shop keeps asking him for money, and he just brings by another wheelbarrow on his way home from work.

First thing I’d be doing is asking for a detailed list specifying EVERYTHING done or added to the car and the price at which it was supplied. .

That is a huge amount of money when a new box and rest of the drive train or brakes are not factored in.

Thinking you should have just gone for an LS build. Good chance you’d have still come out in front.

Sadly you live and learn..

That would be on the invoice when he paid the 40 grand. If not the shop opens themselves up to more lawsuits.

This really depends on your income. For instance for the same build, a person with half the income will have twice the time in his and it all boils down to time spent.
