I've just bought a fresh 50,000mile evo 8 engine which I'm gonna build into a proper badass. I've read, read and read a little more on various stroke or not threads, but I don't seem to come any closer a decision.

Here's the deal. I want to make reliable 600ish hp but i can't figure out whether i should go 2,3 or 2,0? The car will be used primeraly as a streetcar, but deff gonna be used on tracks aswell.

If anyone can make af complete setup (crank, rods, piston etc) I would be very thankfull.

 

BR2.3 rpm, 6266.

 

BR2.0LR would work as well

 

Well, thanks but that did'nt help much..

Maybe I should mention that I'm new to 4G63 and pretty much all other piston engines, as I previously had RX-7's..

What does i take to make 600ish relieable hp from a stock engine, assuming I'm going 2.0. New crank, rods, pistons? which brand, comp ratio, and so on. It sound stupid, but I love an race-like engine, aggressive idle and things like that. I don't know any other way to descripe it. I'm from Denmark, so my english isn't really the best.. Thanks

 

Bump

 

A stock block has been proven safe at that level assuming tuning is done well and the torque is well within reason. With that said rods and pistons are about it.

 

They are many shops you could call to get some advice. I'm sure they don't mind helping.

 

crank: in order of cost
stock 100mm
stock 100mm nitrided
manley forged 600$
manley billet 1400$

wiseco asymmetric pistons 600$
rods: 600 hp doesnt need billet rods
any after market rod would do.
300-750$

fp black BB.

 

I would love to call experts and get advices, but as i live in a non car friendly country which hasn't got a single evo or even JDM car tunershop it's kinda hard, but thanks for the advice.

..

If i understand correctly, a stock crank would hold up, but a aftermarket is preferable? What about the comp.ratio of the pistons?

Thanks for helping out with these (probably noob) questions

 

Stock crank is fine but some prefer a lighter, stronger one so they go with billet cranks. I'm not sure what fuel you plan on using but a 2.0L 600awhp pump gas car is not the funnest thing on the street. At 530awhp on my stock 2.0L, it was fast but the fun didn't start till 5k and peak torque wasn't until 5.8K. Not the most fun. A strokers the way to go for a primarily street driven car imo. Comp ratio really all depends on what fuel your running. If it's difficult for you to call some of the big shops, send an email. I'm in Europe too and MAPerformance has helped me out a great deal thru email.

 

what kind of track?

 

Mostly time attack, maybe a couple of drag passes a year

 

In that case I would go with stroker motor, either 2.3 or a long rod 2.4. All personal opinion tho.

 

Okay, it seems like there's about as many opinion as people.. I'm used to rotary so i don't think the lag would be too much for my drivning style, but then again, I got no experience with piston engines so i can't really say..

Keep the opinions comming, I aprreciate the your experiences..

 

I too came from rotaries. In my opinion I like the 4g63 a lot better. To me it's more simple to work on.
