I am a Porsche advocate and owner . I owned stock GT3, TT 997.1 with 750hp by Evolution Motorsport, stock Cayman 987 Edition 1 and now a 987 Cayman modified in all aspects as a new project.

This is a 987 Cayman that I want to enjoy at the track so decided of giving it a facelift in looks and performance. After a body kit change is now undergoing the process of a complete power and performance increase. Why a Cayman, because is the best platform that Porsche has build so far, the middle engine is a true plus that just lack hp for the perfect track car, to my standards.

A few months ago, I posted recommendations about Proto-Tech and David Hart as a tuner and fabricator. I did not know this tuner but it was fully recommended to me by TPC Racing since they are an installer of their systems.

I received many words of advise, some favorable and some not so favorable about what I was attempting to do, after a deep thought, I decided to try what Proto-Tech and David Hart were promising. Here is the interesting part.

These are the numbers that Heart is promising of achieving:

Current car 2.7l, 6500rpm, bore 85.5mm, stroke 78mm, compression 11, boost @ peak -0.02 bar -0.25psi

Projected performance: 7200rpm, same bore and stroke, C/R 9, boost 0.95bar 13.75psi, new twin turbo at 76% efficiency, effective C/R 17.42, projected HP 544 at a torque 428.

In addition, Proto-Tech is installing their E85 fuel system that they advise should increase HP by 40-80 hp for a total of 500+ hp after is all done.

It is also important to note that a suggestion by the tuner was to make the engine stronger to allow the new increment in HP so the engine was removed and is re enforced with stronger rods, pistons among others.

The car has been at Proto-Tech for 2 + months now and is on the final stage of putting all back together and should be done in 1 week or so.

I seen some post of TT Caymans but no final outcome so it will be interesting on the final HP and performance that will be achieved.

I will continue the post with pictures and videos of the making as well as the final dyno outcome and some video at the track.

I am looking forward to see what the final outcome will be and how will the car performs with higher hp.

I know this is a crazy build and if we get to the numbers projected by Proto-Tech, this will be a very unique Cayman to really enjoy at the track and street.

 

this is simply AWSOME!!!!!!!!!!!!!!!!!!! cant wait to see the results keep us posted please..thanks

 

Sounds great! Looking forward to seeing build photos!

Wanted to add what is being done to the engine:

Upgrades in Rods, custom head studs, bearing main and rods, Crank cradle bolts, custom turbo pistons and rings, viton gasket and seal, custom baffle & door oil pick up, sump pan mod, IMS upgrade, Oil and filter.

Regarding the new turbo system, this is what is going in:
Custom twin turbo, charge cooler assembly, radiator, carbon fiber air shrouds, custom header, custom stainless steel exhaust, custom variable vain turbo, new air induction system, new program DME

Need some help in any recommendations of what type of Gauges to install, i am trying to make it look as factory as possible. If someone uses some at the time, please recommend

 

Not sure how many gauges you want to have, but I would look at an Android Tablet + ODBII Bluetooth Scanner + Torque App

You can make any gauge you want, and make them look the way you want from any information you get from your ECU through the OBDII

I use it on my track only E36 M3 with LS2 engine, and it is very useful, besides that you can log info as well

Thanks Mike


I neve seen something like this it sound interesting. If you can, send me some pictures.
In addition, I am trying to get gages for the new turbos to show the Boost and Air Flow, I am planning to find a gage that will fit in the center electronic chronograph space, any ideas or suggestions

 

The car engine is done, the tuner is just waiting for the new gear box Limited Slip to assemble it all and put it in the car. After that what is left is the fabrication of the headers, turbo installation and mufflers.

The new suspension, brakes and other cool toys for the track should also be in and on the process of installation

We are in the final stage; hope to get the car done by next week.

I am posting some pictures of the engine work. I got lots of videos of the process, I will try to put a video together because its been an interesting build

Cheers

 

Would love to see this in person when it's ready.

 

Sorry I did not make newer posts but was traveling; anyhow,the engine is all done and back in the car. Before we could get to that someadditional work was done to the transmission and clutch, as I explain below, Ipost some new pictures of the engine done and others like the new clutch

This is the other work, we are doing:

Clutch and flywheel: because the new hp, and for bettertrack performance we decided to change the clutch with high clamp load pressureplate, Kevlar carbon fiber hook stile center disc, light weight fly wheel withremovable friction surface.

Limited Slip dif: since the original car has more tractionthan power, since we turbo the car making new great hp, we are using a limitedslip at 45% on acceleration and 60 on the negative side when you lift and geardown

Manifold tie downs and resonance flaps: made tied down onmanifold so they don’t blow up and the resonance flaps are adjusted to handlethe new boost and does not close these valve so the performance is not killed

Deep Sump: added new sumps & baffle plates to allow forbetter oil flow, very much needed for track use due to high runningtemperatures and different g forces

 

Took some pictures today from the fabrication of the Turbos, charge cooler, and rest of build, this are very cool pictures because now is going from a project to the actual finish product. Their are doing the last steps on the fabrication making sure it all fits in a reduced area, should have it all done by the end of next week.

 

Looks great!

 

I havent had the time to make new posts. Take a look at the pictures, we are almost done, looking real good.

Cheers

 

so this car was origianally a 2.7 liter ? same as mine so this is very interesting to me .. I wonder what the cost to do this transformation is costing ..over 20K i assume ..what is the liter size now ?

simply amazing thread and car I would love to do this to my cayman

 

Hey Fluid987:

Thanks for the comments, yes is originally a 2.7l and it will remain a 2.7l. All the added power will come from the TT turbo and the e85 fuel system. It was probably not needed but I paid to get the engine (re enforced) if I can call it that way. As posted, I changed and upgraded some parts of the engines like, pistons, rods, heads etc to make sure the engine was on the safe side and under its maximum capacity now that the rpm & psi will increase.
There was no need to increase from a 2.7l but it was possible since the engine was taken out so some extra work was possible. Anyhow, I decided not to and agreed with the tuner that it was not necessary since my goal was to be around 600hp and it will be easy achieved with the 2.7l.
I guess there are a couple of ways of increasing HP, one is by increasing the engine size and the one we are doing which is by adding hp via the turbo and psi.
I see some Caymans with bigger engine and they drive excellent and have the added power so I guess is a preference on the tuner of what to do.
The cost is around the 20k to 30k you mentioned; however, I am spending much more but due to engine work, suspension, brakes etc.
If you want to do it to your car, I recommend that you call Proto Tech, David, and chat with him. Moreover, wait till my car is done, hear my comments, and let’s see what it ends up making on the Dyno.
It’s been a good 3 months of work and wait but we are almost there, the car is in the last part of the fabrication, the final stage and the car should be running by next week, then the details with ECU and tuning will come into play and I have to put some miles in the car before we take it to the Dyno, then the actual numbers and performance will be proven.
I did not know what to expect from Prototech at the beginning but I can now say that he might take some time in its work, but things are done right. I like where we are now and promised things are done, besides, I seen some cool and powerful builds while my car has been there, hopefully mine will be another one; the guy knows what he is doing. Check his web page and go to you tube link.
I will keep you posted, you have a great advantage, you will see the results on my car and this will give you all the heads up needed.
Cheers
