2L Stroker Build

[cmiguel32]

My current Frankenturbo setup is a lot of fun, but I've decided to eventually go with a bigger turbo. Started this thread to document the process.

I recently picked up a used 2.0L stroker engine with the 034 06a stroker kit (less than 10k miles on it).
I just got the head back from my local machine shop where they swapped the components over to AWM head and will post pictures soon.

The AWM head now has the following:

Ferrea valves
IE titanium valve spring/retainer kit
IE valve guides/stem seals
IE Street/Strip Cam set

I'm in the process of tearing down the bottom end. It's going off to the machine shop to get inspected, hot tanked, crank polished, etc. I'll be posting photos of the tear down next week.

I plan to drop the engine in with a stronger clutch and mate it to the F21 set up.
The eventual plan is to put together an EFR 6758 w/ a T4 twin scroll housing and the Full Race tubular twin scroll manifold.

Any clutch/flywheel recommendations would be greatly appreciated!

Why not do an efr 7163 twin scroll?

Thought about going bigger, but I'm fairly concerned about breaking 5-speed transmissions.

Clutch:southbend

what are your power goals for this setup??5 speed transmission doesnt like more than 350whp.If you want more you should look at a 01e bulletproof up to roughly 800whp.

Nice build specs! I'm in the midst of a 6758 efr build as well. There's not enough info out for this turbo on our platform. Mine will be 1.8l, 8.5:1 compression, stock head/cams. Vband turbo and manifold.

I too am concerned about the stock 5spd, but have found very limited info on rebuilding/upgrading the internals.

I plan on using the jhm rs4 clutch kit. Can't beat oem equipment. I've not heard good things about southbend in my research, lots of premature failure/wear complaints.

JHM clutch kit hands down..

What brand of vband housing are you mating the EFR with? Have any pics?

Pag parts vband manifold. They then modify the efr 6758 .64ar from the original t25 flange to vband. I don't have the kit in my hands yet as its being fabricated.

Here's is a picture I was able to find the assembled unit.

Looks nice what kind of number are expected with that setup????Also I wasnt aware a .64ar was available for the EFR.Or is it a custom one off??I'm looking into a similar setup but most likely will be using a s257 super core.

[Mr.Avant]

.64ar is avaliable on the b1 efr frame. The Vband flange is a custom job. I'm really hoping for 350whp with 93 Oct + water meth. We shall see.

I had a southbend clutch at one point and it ended up breaking the clutch fork.

Everyone has their preference.Ive had a number of southbend clutches in a few of my cars.I never had any issues.All I can say is they stand behind their product.I wouldnt recommend spec because the clutch material like to delaminate.I guess each clutch has its flaws.

Awesome to see you take the plunge! I was in your very shoes 6 months ago so good luck with the build. My target hp is about 400 whp and im probably pretty close to that on e85, so my suggestion is why not go e85? As far as the clutch goes I chose the jhm rs4 kit and have nothing but good to say about it, very smooth engagement no chatter, very stock like feel. After it heats up from some hard driving I dont feel any fade still grabs quite well.

Unfortunately e85 is not avaliable around me (Canada). 93 Oct + meth is the best I have at my disposal for a daily vehicle. Are you using the efr series as well?

No unfortunately not. I bought a whole gt3076 kit, needed to stay within a budget that I had set but as things came along I spent more money than expected. It always came up to where I needed this part to make it work then that part. I'm finally to a point where all the time, money and effort seems justified, the cars hauling ass lol. Ive raced some pretty beefed up cars running very respectable times at the drag strip. Once again im reaching the limit and need to spend a little more money to go up in power. Currently im at 98 % injector duty cycle at 7200 on 22 psi. The next step is a return style fuel system which I am in the process of sourcing parts for.

[Mr.Avant]

What fuel pump and injectors are you using?

I just finished converting a b5/passat rail with adjustable regulator to -6an lines. I intend to run new feed and return lines with 1:1 regulator.



Sorry to thread jack OP. But it's good knowledge.

I'm running the bosch ev14 converted to 1000cc with a aero 340 lph in tank pump. I've reached the ceiling of fueling pretty quick due to loss of fuel pressure in the manifold during boosting. I'm going to use the n80 line as my return to the tank and re route some lines. I to will be sourcing a b5 a4 fuel rail. Maybe you can give me an OP some ideas of doing this if he ever chooses to go return style.

Yes, please! I'm looking to continue using e85 and a return system is definitely an eventuality.

Yeah e85 on a big turbo feels real good. Never been in a meth injection car does it allow for the same amount of timing advance as e85 or more?

[Mr.Avant]

Quoted from my build thread.

I'll put it here so we don't clutter his thread.

After cutting of the return barb, I was able to use a 3/8 (0.375") compression fitting. The line on the rail measures 10mm, or 0.393". With some careful bending and sanding I was able to get the back of the fitting and the compression furl far enough onto the line. Some people are skeptical of compression fittings, but because it's only return pressure, plus how tight it went together, I have no worries.

The feed fitting was much tougher to find, it's a m14x1.5 inverted flare to -6an adapter. 034motorsports makes one thankfully.

Not true at all...
It can hold a lot more than that.

Paging Mhood....

[PreciseD]

I would definitely go with the EFR 7163... It is a better turbo all around and your 5 speed should handle that with no problem...

That's a relief. I know a guy using a 5 speed with a 2.7t making way more power than me and it's been holding up fine for a while. I do cringe at times when I'm beating on the car but she responds very well.

Didn't you break a transmission? What was the condition and power level?

Haha I split a syncro in half.. I had a grinding issue going into third before I built my engine.. My replacement trans has been solid for the last 1500 miles of hard driving... I would say I am over 400hp right now on the base tune.

Im right around the 400 mark but after a night of racing these ss camaros and scat pack challengers I need a little bit more power. After I beat the scat pack I got approached by a ls1 z28 with a 200 shot of nitrous. Thats how much pu$$ies these guys are.. Anyways I need more power and I really want to know when the 5 speed will be stressed. Guess I'll find out lol.

Guess you will have to be the guinea pig.... But I have seen 5 speeds pushing more TQ than we are... That is the limiting factor not HP...


Which track are you running at?

Racing in the street. I'm contemplating building my small port head or my AEB for high rpm. I've been doing some research and I find mixed reviews.

[demonmk2]

It's all about shift management, especially going into third.
Might want to consider a flow control valve too

Mike hood has run 10's with a 5 speed.

Shift management is not going to control where my shift point is.

How you shift gears...... Not when.

Or you can learn how to use a clutch lol...

[demonmk2]

Well, it's mainly used when running an aggressive clutch
Third gear engagement and release is where things can go wrong because
Of the way the transmission is designed.

So my very aggressive clutch is why by 3rd gear syncro exploded? Or just a weak syncro?

It blew because you're one hell of a driver going into 3rd!

Precise is this an 01a? What power level are you planning on stopping at?

I have an 02x in there now but I have an 01e ready to swap in, just need to find the time.. I was thinking about going to the EFR-8374 but I haven't even seen what the 7670 can do.. I was supposed to take it to UM this week but work is too busy and I can't get the time off.

If I can get to 600 I will be happy...

[cmiguel32]

Update:

Bottom end is in great shape. Just finished sourcing the rest of the parts. Block is going to a local shop for assembly next week -- Obviously after the deck is cleaned up.

Ended up going with the stage 4 JHM rs4 clutch/flywheel set up.
Picked up another IE billet crank pulley/arp bolt combo and adjustable cam gear kit.
