Cost of 400 h.p.?

[Nader]

What would it cost to get a solid 400 h.p. out of a 3.2 Carrera non-turbo engine? Let's assume I farm it all out for the turbo conversion, and the engine will be rebuilt with new P/C (maybe bigger displacement), cams, etc. A quality build. Just testing the waters, build up my car vs. get something faster...

[quattrorunner]

A zillion $ if you farm it out.
If your careful, and do most the work it will be about $8k for parts and stuff.

You don't need bigger anything. Just lower compression ratio and run a turbo to whatever boost achieves 400hp.

The stock Carrera 3.2 cans are the exact same profile as the highly sought after SC cams a lot of guys here have.

I suspect 10-12 PSI of boost on a high-50/low-60mm compressor sized turbo will get you there easily.

I believe Los Angeles dismantlers has a factory 3.3L 965 turbo engine complete for about 12K(listed on Ebay)

Sell your current 3.2, and you'll only be about 7K away from a turn-key turbo engine.

[Nader]

Not to be rude, but when I say farm it out for a quality build, that means me not touching it myself, and not swapping in a stock used engine.

Throw out some numbers; $20K? $40K? How much for a stout, reliable, streetable 400 h.p.?

[jpnovak]

Drop the compression to about 7.5 or 8:1, add 1 bar boost. A K27HFS would easily do it. Play around with different turbos if you want. Add aftermarket EFI so you can tune it right. You already have ported heads, great manifold and running Motronic EFI. Just plumb exhaust, turbo and intercooler.

Whoosh! Enjoy.

Since you already have a G50 car you are all set.

Thanks for that. So are the Turbocraft guys zillionaires?

Not looking for instructions on how to get there, just dollars. I've already had the experience of building/rebuilding race engines for motorcycles and vintage race cars. I don't have that in my anymore. I just want to drop off the car, and pick it up 6 months later (or however long it takes) with 400 h.p.

Exactly. Thank you.

Talk to Chris Carroll of TurboKraft and Todd Knighton of Protomotive. 2 different approaches to the end goal (aftermarket EMS vs Motronic).

[cole930]

If you want horse power the Turbo God is your guy. He can get you 600Hp on pump gas. Horse power costs money so it's just a matter of how fast you want to go. And Chris is one of the finest people I have ever known.



91-octane gasoline:

600whp / 488tq @ 1.0bar

672whp/530wtq @ 1.2bar


100-octane

721whp / 583wtq @ 1.3bar


E98 ethanol:

652whp / 510wtq @ 1.0bar

800whp / 680wtq @ 1.5bar

Just my estimate. You can easily go upward very quickly in cost from here. I have indicated a comparison with upper and lower limits.

EFI based on Megasquirt, new injectors, wiring, connectors, ignition upgrades about $1500. AEM is above $3K last time I checked. Motec would be about $5K.
New pistons - JE $1000. Mahle
930 headers ($400 - $2500) Upper price range is Rarelyl8. Do you need heat? Then look at a custom conversion with 993 Heat exchangers. (They work very well)
Turbo could be $800 for a good used or $2200 for brand new.
Custom intercooler can be welded using a $300 core or go all out with one of the many excellent choices. I think TurboKraft makes one specifically for the 3.2 manifold. I am not sure on current price.
I would probably add another $500 to $1`K for misc stuff like BOVs etc.
Then there are all the installation and fabrication costs. There is a lot of time putting together a system. Consider your local shop rate when calculating costs.

You can do this on a budget if you are savvy and shop carefully.

[quattrorunner]

An engine rebuild with p&c etc is going to run $15k
Then the turbo goodies to run with stock motronic would run from 2k-$5k depending in your parts used or more. Then to have someone put it together might cost another $1500?
A shot in the dark sort of. This is a zillion to me cause I'm cheep. Would be awesome project good luck.

[Tippy]

Protomotive used to charge I believe $25k for rebuild and 500+hp, but that was years ago.

[speednme1]

Nader, prices will vary from shop to shop. What parts you/builder choose.. will also keep your prices up or down. Keep in mind that your budget should include suspension and brake upgrades as well.

The thought behind my build was reliability first....then hp. Choose your builder well, and discuss all aspects of the build including the time frame....oh and $$$$$$$..

[Tt surgeon]

20k for that kind of hp from a na engine. I'd call Patrick motorsports.

[Robbbyg]

Another way to get the performance of 400hp with the hp you currently have with 0 dollars

By making the car lighter

Getting the weight of the vehicle down to roughly 1500lbs...that would be a neat trick!

[krasuskyp]

I no jokingly hope / ASSume you are factoring in the cost of:

enhanced brakes / suspension / wheels & tires / trans beefification...

...when yer calculating the cost of yer query?

otherwise

you've got a 400hp turd

a dangerous and particularly pointless one, at that

Please oh please don't let this devolve into (yetanother) I T/C'd My Car and Now I Regret It saga... just sayin.

Whatever rocks yer world otherwise, I guess.

If I'm completely off base (blame Kettle One, GennyCream on Wed Sabbatical - hey, it's a SNOWDAY tomorrow werk already bag'd, have fun @ werk tomorrski all you fargin sneaky sunbelt bastages!), then... doooo eeeeeeeeet / enJOY in good WOT spirit!

[jwasbury]

So many variables to be considered...

You could get meaningful power gains doing a low pressure turbo set up and retaining the stock P&Cs. Assuming your engine is on good shape the could be done without opening it up.

Give a call to Chris at Turbocraft and let him talk you through the options.

If you go the full monty route with engine rebuild and send the car to someone like Chris, don't get any dirt under your fingernails, I say plan on 40k...

Would be a cool project, but then you have to ask yourself why not sell the 3.2l Carrera and pick up a 930?
