Al,

Nice choice to go with the stroker set up! hopefully i will be doing the same next year. how does the spool up of the turbo feel? the reason i ask is i would see the same spool in a 35r and 2.0 at my elevation. if i get the stroker kit, then it would be 4500rpm, which i still dont know if its worth it. i dont expect stock spool, but i want a usable power band. the turbo decision has been very difficult for me, im sure you know since i have been trying to figure it out for months now.

 

Cool, thanks for the response

I've been doing a bit of research into the methanol injection, which i'm planning on buying next. I just want to make sure I know as much as I can before jumping into anything..

1. because of the corrosiveness, do you recommend people to stay away from methanol for a daily driver?

2. if i run methanol injection (with bolt-ons and a WR turbo or 20g tme turbo), how often should I change my oil? and should i stick w/the oil that mitsu recommends? or should I use a different oil?

 

What up Al, After blowing my stock motor up with Alchohal injection, I had asked you which build I should go with the Buschur 2.0 or 2.4, your responce, "Always go with a 2.0", Its a good thing I didnt listen.
Im glad you see the light now, good luck with your new setup....

 

On standard cars with normal pistons, normal piston ring gaps and resaonable boost levels which use the methanol injection to LIMITED amounts - such as the relatively small 7 jet we supply in our alcohol kit I doubt that there will be any contamination what so ever.

Remember, my car is set up for 700 whp use levels and everything is super LOOSE on the piston set up. Also I dump 10 times the normal amount of methanol.

With 40 lbs of boost there is so much blow by that you must literally zip tie down your dip stick or it will hit the top of the hood.

With a standard road car on alcohol injection I would suggest use factory oil and change every 3,000 miles.

 

how did u blow ur motors w/ alcohol injection?

 

Sadly his kit was malfunctioning or misinstalled and he went drag racing with the kit working intermitently. He held down the gas even thought the a/f was reading lean.

Its super imporant for those with alcohol kits to check them on a regular basis and to STOP boosting it if there is any problem with the function of the kit.

 

thanks for the quick replies Al, much appreciated!

 

Not quite how it went down, but I dont want to ruin Al's or SMC name here so Ill leave at that, but surely dont make me look like a ****head by saying "even though the A/F was reading lean he held down the gas".
Or to even say that maybe it was misinstalled, even though you drove/tuned this car to see everything was in perfect working order, come on Al.
It literally took about .0001 seconds for the motor to nuke, fun was over after that, and there were plenty of witnesses to account for what happened, people who where actually there (smogrunner for one).

 

I really do not know whay you bring up your alcohol kit problem in the first place in this thread as it is a totally unrelated subject.

but - bringing it up - people are asking questions and should be given clear answers.

No one is trying to make you look like a * * * * head as you are a stand up guy for sure.

However in your case, I clearly recall with vivid detail our phone conversations before the incident in question in which you described the a/f going lean intermitently. I recall my advice - "TAKE OUT THE ALCOHOL KIT AND SEND IT IN FOR WARRANTY REPAIR TO SMC" and / or go over install to make sure there are no loose connections, etc.

Obviously when and alcohol kit is going on and off and spraying part of the time its a serious condition

For WHAT EVER REASON you elected to continue using the car - and the next thing I hear is that you were at the TRACK of all places and the car went lean due to alcohol kit failure

People who are reading this with alcoihol kits or considering alcohol kits must realize that constant monitoring of the alcohol kit is REQUIRED and ANY instance of improper operation or problem must be followed up and tracked down

 

Glad you are happy with the engine Al, can't wait to see the records you are going to set with it.

The stroker for sure makes a larger turbo'd car more streetable. The low end on a 2 liter with a GT35R, for me, sucks for daily use. Up top it is fine, down low is horrible. Putting the stroker engine in the same car really wakes it up. Running a stroker engine with the GT40 to me makes the GT40 feel like a GT35R on a 2 liter.

We just finished dyno'ing a car that went from a 2.0 liter to our 2.2, both built Stage 3 engines. NO other changes except for the shortblock.

The power over 7,000 rpm was the same but under that the HP and torque we much better with the stroker engine.

Your blowby is not normal. I run 37psi on my 35r with a m15 and m7 for alky jets. My dipstick don't pop up and its old and hard. I dont even run a catch can. The only vent is the valve cover one wich is just left to dangle over the tranny. I figured when I see oil gather I would add a can, but I never do.

Here is the setup for those that might be interested. JE pistons with .065 piston to wall. Yes they are noisy when cold. Hastings rings with .018-020 end gaps. The alky does reduce bore life as it washes oil off the cylinder and ends up diluting the oil. I change the oil at 7-800 mile intervals and it prolly should be done sooner.

 

change oil every 2000 mi should be fine? w/alky kit

 

When we last left this thread it was last week I was finished tqing down the head and ready to pump up the boost. The car felt strong, real strong, all that awaited my next chapter of vehicular madness was a prefunctory pre-boosing compression test. Sadly the compression test identified generally low cylinder compression and a high variation between individual cylinders.

This sad turn of events lead to a quick investigation which revealed that the pistons had hit the exhuast valves

it seems that when Buschur configured these pistons they did not anticipate such ultra high lift cams as I use with 1 mm extra sized exhuast valves.

In any event - make a long story short and my pal David Buschur came though with flying colors - offering me a brand new STROKER engine with some larger exhuast valve reliefs cut in

So i tore apart my engine shipped the parts to Buschur last thursday and loaded up my car today on the trailer and took the ride out to ohio to get my new Buschur Stroker engine installed

Buschur is a good guy to take care of my whole problem - no questions asked

Also - he also redesigned the piston and orderded a new batch that will have the larger valve relief to prevent this problem from occuring again

right now i am feeling STROKED to know that ALL that power I felt last week on this engine was with all the exhuast valves bent and not sealing - translation - MORE POWER COMMING SOON

I never worked so hard in my life - I landed at NY from LA at 2:00 a.m. Tuesday AM and by the end of the day all my gear, parts and car were loded up and I am in Ohio ready to drop my car off tomorrow am at Buschur for his master work

More updates tomorrrow

 

Nice to se things going well for you. A stroker will aslo let you get away with running a more aggressive cam since they will pull more vaccuum. You might want to give Robert at FP a call and see if he can whip up some of the DSm "stroker" cams for your evo.

 

Don't get too "stroked" Al. I need you to be well rested and fresh for tuning my car Oct 22. Moreover, take your time building your new motor, we're relying on you to set some records.

Got any extra parts you want to get rid of, cheap? JK, well kinda .
