Turbo 1600dp streetcar 28+psi
I am going to build up a 1600dp with a turbo and efi to handle 28+psi for a 1969 beetle street car. I'd like to make at least 200 whp on street tires, 0-60 in under 5 sec, redline at at least 6000rpm. I'm currently thinking this build:
CB Performance 044 Super Mag Heads std bore 40x35.5
Chromoly pushrods
Titanium Retainers
Dual Valve springs
CBP 1.25:1 rockers
CBP low profile high flow center mounted manifold
CBP 40mm efi throttle body
CBP gen4 efi and ecu
Mahle forged piston and barrels still bore
Stock case
CBP 4 quart oil sump with FRAM oil filter adapter
CBP Lightweight 8 dowel flywheel
My main concern is are those heads good for this build, are the rockers too big or too small and I have no clue what cam to get, is the stock case good to use or should I upgrade.
Is there anything else I should consider, thanks.

Re: Turbo 1600dp streetcar 28+psi
What fuel are you planning to use? Why 28 psi? Don't buy rockers till you have a cam. I highly recommend upgrading the springs to CBP VW650s if you plan to run that kind of boost at big rpm. Are you planning to spin the stock crank, rods and pistons above 6000? That's brave. Not to say that it's not possible, just not a great combo for long term reliability.

Put your money into an intercooler and ignition control.
E85 fuel will help a lot.
200 whp would be about 240 crank hp or somewhere around there.
Using the RB Racing calculator you should be able to get that at 21.5 lbs boost at 130 degree IAT's and 6000 rpm.
Your intake temps will be 262 degrees out of the turbo so to get 130 degrees after the intercooler you need an 80% efficient intercooler.
You will need 327 cf/min of air so find a turbo that will put that out at a minimum.
If you increase your rpm you can lower the boost or get more hp.
Start a build page and post pics....we all love pics.

Re: Turbo 1600dp streetcar 28+psi
I did plan on going with vw650s. Originally I was thinking 14psi with a gt2554r with a misimoto intercooler and turbosmart bov and wastegate but I don't think that will put out 200hp, maybe 150. I want to compete against the naturally aspirated guys with 2275, 2332, and 2387s that's why I say 200+ hp that's about what those motors run in street cars. As far as rods go I planned on chomoly ones in stock size but I don't know if aluminum ones would be better or weaker. Reliability is key with this build I want to build my car to seem like it came factory with a turbo. Thanks for your 2 centsChip Birks wrote:What fuel are you planning to use? Why 28 psi?

Re: Turbo 1600dp streetcar 28+psi
I want to keep run 93 pump gas cause I don't want to go out of my way to worry about finding a gas station with e85 around where I live. I plan on getting an msd 6al ignition and 2step and a top dollar Misimoto intercooler. As soon as I start the build I start a build page I want to do as much research as I can before I dump my money into this.Clonebug wrote:Put your money into an intercooler and ignition control.

Re: Turbo 1600dp streetcar 28+psi
What are you using for an EFI ECU???
Why waste money on a MSD ignition when you can have direct control with most quality EFI setups.
Megasquirt will take care of FI and ignition in whatever way you want to set it up.
You might want to do a little research before spending money.
200 whp is doable but 28 lbs on pump gas is going to be a challenge.
I have been running 21-22 lbs for most of a year but not without issues so be careful.
Make sure you pick your parts carefully all the way through the build.
You will need injectors, heads, cam and exhaust along with the correct turbo to make what you want.
Since it is a street car the turbo will be an important decision in order to get the horsepower where is usable on the street.

Re: Turbo 1600dp streetcar 28+psi
Thanks for the point out. I plan on getting cb performance gen4 efi ecu but I might go with a megasquirt or haltech ecu what do you recommend. If I went e85 with 21 psi will that be a more realistic build. I am only doingredients research now I'm new to efi and turbos so I want to plan it right before I start it.

Re: Turbo 1600dp streetcar 28+psi
Sounds like you have some studying to do. Aluminum rods have no place in a high mileage street motor.
Where do you plan to mount the air to air intercooler on your rear engine VW? Do you plan to run a deck lid?
The CB gen 4 ecu is a very capable computer. You will have good support from Mark and Pat over there. It definitely will have 2 step capability, as well as offer good distributor less ignition control.
I will put in a plug in for my friend Mario at thedubshop.net. He is a stand up guy who cares about his customers. I highly recommend him for all of your fuel injection needs. He deals mostly with megasquirt, but has also gone through the effort to bring a sweet new ecu to the vw market. Also, he is in the middle of a nice sale that ends monday. Lots of good deals on VW efi parts.

Re: Turbo 1600dp streetcar 28+psi
Thanks for the info. I plan on placing the intercooler above the engine underneath a dragster wing with a big hole cut in it for the intercooler to get air. I'll have a decklid mounted far from its stock position Ike AZNs dung beetle. I'll check thedubshop.net out.Chip Birks wrote:Sounds like you have some studying to do.

If your goal is "only" 200hp or a tad over I would say it is just no need to go turbo. You are only over-complicating things by going turbo. I would much rather build a 1915 NA or something similar. With a good combination of parts you will reach 200hp.
If you are set on turbo I would build a really good, strong and future proof long-block. If it was my engine I would use Mini Wedge port heads, a mild Engle turbo grind cam, CB650 springs, a DPR crank, good rods with good rod bolts, choose a ECU where you will easily get the support you need (important), crank trigger, AA thick wall 92mm barrels, Mahle pistons and set your goals higher. 300+hp should be rather easy at decent boost with those parts. A lot more if also build a good exhaust and a good, efficient intake system in combination with a good turbo.
