Choosing the right Buschur Racing engine for your build.
I look at It like this. When a customer comes to me for a tune I ask him two questions. 1. Which fuel injectors are you running? 2. What octane gas are you running?
I don't need to know what compression it is, what turbo is on it, who ported the head, what intake it is, the displacement or anything else. It is completely moot. With the correct parts WINNING (haha, celebrities!) happens, with one incorrect part suck happens. I know for a fact that 33-34 psi of boost on 93 octane and 11.5+:1 is NO problem, the compression is moot.

Thats what im talkn about. I ran 30-32 psi on my 2.4 with 10:1 cr (BR 2.4) on pump and was PERFECTLY fine.
Most people were like, "OMG r u crazy!?",... no im not.
I never heard of the Winberg crank until a week or so ago. The price when I found out about them was more than a shortblock. It's in interesting looking piece.
I've been extremely pleased with the service and parts we've gotten from Manley. I'm a loyal guy. I've got a call into Manley with some requests for some custom parts to be built, rather than jumping ship to unproven parts I'll stick with a company I've got a good relationship with and see what happens.
I'd be willing to use the Winberg crank in an engine, someone just has to step up and pay the price. They are also 6-8 weeks wait time to get one from what I understand.

Concerning the crank, we'll talk at the end of the month- i think you found your Guinea Pig David...

David,
Winberg crankshafts for the 4G63 have been available since January 2009. I currently have 88mm & 100mm Winberg crankshafts in stock, no 6-8week wait time. The 88mm & 94mm are our most popular selling stroke sizes. I am currently having more 94mm crankshafts being made that are about 10weeks out.
We also have 6-bolt 4G63 crankshafts as well. Got a handfull of guys in south Florida & Puerto Rico that love them.
Check out this thread below for more info on the crankshaft.

Thanks for all the information. I have a question in regards to your motors. I am sure you have probably answered this question before in another thread, but unfortunately I couldn't find anything with searching the site.
When it comes down to the motors you build, which one to the best of your knowledge has been the most reliable for your customers when comparing the 2.0 or 2.1 to the 2.3. I understand there are several contributing factors that can cause a motor to fail prematurely, be it a different tuner, driven hard on a base tune, not broken in properly, poor maintenance and so on.
The reason I ask this is because of the different styles of engines you make can contribute to engine failure, when you look at what they are built for. Like your high revving 2.0L. The power down low isn't as good as say your 2.3L, so you have to rev the crap out of it to make power/be enjoyable. Those high revs all the time could cause eventual failure. Then you have your 2.3L. Doesn't rev as high, but makes gobs of down low torque. That extreme tq will also have an affect over time.
Coming from a Honda we always keep the tq down for two reasons. One is because of good old FWD lol, and the other is for reliability. The motors I am used to can rev high all the time and last.
Since I am looking at an EVO in the near future, your thoughts on this matter could greatly help in my decision of which way to go when looking at a high revving motor, and a low end tq street monster.
Thanks for your time.

I was looking for this thread to bump it to get some much needed information out there and see I missed some old responses.
I did look into the Winberg cranks, thanks for the link.
As for the most reliable engines, that is impossible to say. Seriously, if we haven't built 1,000 4g63's by now I'd be shocked. I wish I had kept count all these years. Considering in a few short years just for the EVO we've built over 500 double pumpers a 1,000+ engine count has to be more than possible.
Anyway, I can't even guess. Personally, I really-really like the 2.3 for nearly every single build there is out there. If it's not an all out top end drag car it's what I recommend.
Emery at STM has had some great success with our 2.0LR engine and is recommending them for a lot of his guys. My only problem with the 2.0LR is it seems to make the least amount of torque and for an autocross or fun street car it's not the best choice. Should live forever though with the rod ratio and such.
So there is my "bump".

how is the RPM2.3 customers holding up? what power and trq are some of the higher guys seeing and what rpms are they touching. i know your car is a 2.3 but are you still going for 8s with it?
do you think ''if one had the option'' the winberg crank would make is ''more safe'' to rev to 9500 or no. it sucks there expensive.

Not gonna lie, I really love this motor! We just made some pretty good numbers with it on a red. 500+ ft lbs of tq and about 580 whp. This car is full weight and runs bottom 10's at around 138. Still even has AC.

2.3RPM's are holding up excellent. I've run mine to 9500 rpm, yes, the plan is still to try for 8's with the 2.3RPM.
I will build one with a Winberg crank is someone wants to pay the additional money.

Do you ever notice 100mm crank motors vibrating bolts loose? I have heard of this a lot and experienced it some myself. Curious if it was a poorly balanced rotating assembly or if this is the norm in your experience. The off boost drivability and tq is unmatched.
Thanks!
Thanks!
