What is needed for a high revving 2.0?

[stockfornow]

Ok, after this thread:

http://www.dsmtuners.com/forums/showthread.php?t=239473&page=2

I decided to sell my 2.3 stroker kit, and go with a 2.0 since it will be more easier to build for my first engine, and besides the rod angle is kind of a bit harsh for a daily driver. And I want to go longer in each gear, with a higher revving 2.0. I was also considering a 2.4 block at some point, but yet from all the people I talked to the 2.0 will be a higher revving out of all of them. So, I'm wondering what would I need for my bottem end, would just some Eagle H beam rods with some JE 8.5 pistons work? And what would have to be done to the head? And how high would I be able to rev it up to, and it'll be a daily driver also. I also heard of the 2.1 block, but I tried searching it here, and don't seem to find any info on it. Can someone tell me about it? Thanks, to all of you. It was kind of hard for me to decide what to go with. And by the way if anybody is interested in the 2.3L kit, I still have it, just pm me.

I dont know about your decision to go with a 2.0 block. For a street car that is going to be daily driven you are going to love the low end power of the 2.3 compared to the 2.0. Also another point you might want to consider is that with a higher reving engine you are going to be beating up the transmission a lot more. And you really dont have to be conserned about the rod angle so much because that only comes into effect when you rev out a 2.3 L engine past 7500. If I was you i would stick with the 2.3, it is just so much easier to make horsepower using the same turbo/boost you would run on a 2.0. The only down side is going to be you shouldnt rev the car past 7500 with a balanced engine. But this shouldnt make much of a difference because it is hard to get a stock trans to shift above those rpms anyway. At worst you are going to have to replace the 13 dollar rod barings about once a year if you really beat the crap out of the engine.
A 2.1L engine is a 2.0 liter crank in a 2.4L block. This increases the displacment because the 2.4L block is a little taller than the 2.0L. You would have to get specialty rods to run a 2.1 and the problem with the 2.1 is that not a lot of people use them and they make all there power in the upper rpm range. No one makes good cams for a 2.1, stuff like that make using a 2.1L engine a real specialty job. Basically a 2.0 is for race cars, a 2.3 for street cars, and a 2.1 for someone who has a lot of money to spend on custom everything.

After you posted this up here I don't really know what to do, stick with a stroker kit that I already have or build a 2.0 or try to find and build a 2.4? I'm really sorry to bring this up again, I would like some people to vote here if you can just to help me decide on what to do? I honestly need your help, DSMers! And please consider what other people have said in the other thread. I just want something really fast, but also something that I wouldn't have to go and rip my engine apart every single year. I would like to to last at least 50K miles, but to be still beating on it.

slowboyracing.com has a 2.1 destroker kit. with that and a built head (cams, springs and retainers) you should rev near 10k

Those are almost unrealistic goals, depending on what you think really fast is. When you start to tune your engine and push it hard, things will break, and it will see faster wear. Having to replace something once a year isnt really a big deal either; just think, you have 12 months before you have to do a few hours of work to your car. I am currently in your place, looking at how to rebuild my bottom end, and out of everything a stroker is right for me because it is on a street car and that is what the stroker is good at. If you want something that will rev high, build your 2.0 but remember, you will rarely get to use the power you have built (unless you like reving to 8k on the street) while the stroker will give you power all across the powerband.

Titanium nitrade coated valves, bonze valve guides, dual valve springs, titanium retainers, kevlar timing belt... Alot of head work. Eagle rods are rated up to 9k

You will need a built head and cams to be able to flow at higher rpm's. Will also need a shortblock that can take it. As well as a turbo that will carry into the rpm's. If you wanna rev anywhere near 8.5k you are going to be spending a lot of money on turbo and fuel supporting mods and tuning. Or you could buy a Honda.

i think one day im going to do the slow boy 2.1 set up.
Anyone running that? I hear you still benefit in torque but are able to rev high like a 2.0

 

[wvturbo2]

what is fast and how much can you actually use on the street ? Is it just for bragging rights or what? I used a 1.8 kit and i can rev to 12k. J/k. 2.3 have better torque, increase in hp and have a nice daily driver. On the street i would think a car that has more low end and doesnt have to wait to 6k to make power is gonna burn you. I;m in the same situation as you I've looked around and been reading and i think i'll end up doing the 2.3 stroker. If you want a car that can rev to 9k with no problems or modifications buy an rx-8

 

[95blackGsTurbo]

For the right price you can rev anything high. Shep revs out to 10K and AMS revs out to 9.5K on there 2.3L.

 

[wvturbo2]

Shep runs a 2.0

 

[beating4g63s]

after seeing evil_eagle make a 9.0 pass I think I'll just save the money and invest in my motor rather then get a stroker kit. 9.0s are well past my goals oh yeah I'm pretty sure yall know his car is still street legal.

 

[95blackGsTurbo]

Shep runs a 2.0

That was implied.

slowboyracing.com has a 2.1 destroker kit. with that and a built head (cams, springs and retainers) you should rev near 10k

didn't they have alot of problems with this motor ?

That was the motor Curt Brown ran in his Evo and it was giving him problems left and right ...then he switched to the Buschur Block and has not had any trouble sense

 

[stockfornow]

So, since I already have a 2.4L crank and H-Beam rods with stroker pistons on them already, I should go and build a 2.3L and don't go thru all the hassle of selling and buying parts??? If that's what you think I should do then I will do that. I also found out that with 2.0 high revving I will need I better transmission to shift at high rpms, where as 2.3L will make power earlier and will only be redlined at 7500rpms, so the trans will handle that easier. I'm really sorry for this thread, but I just really need help. Thanks to all of you.

P.S. Fast (for me): mid to low 11's

And if I can get high 10's I'll be really happy.

 

[DankDSM]

stick with the stroker kit. From all the people i have talked to at the track it is just easier to make more horsepower out of a 2.3 than a 2.0 at the same boost. 2.0's are better when you are running 30+ pounds of boost because you get 2-3 thousand extra rpms to make crazy power. If you already got the stroker kit just stick with that.
And also you would only have to drop the oil pan once a year to replace your rod bearings. Takes about 2-3 hours if you have never done it before.
This will easily hit your goal of 11's and maybe break you into the tens depending on turbo/boost.

 

[stockfornow]

10's......... SWEET. I also found another engine for dirt cheap, it's a 6 bolt 2.4 block G4CS, and I might build the stroker, and then in couple years I can save up and build a real 2.4L block, and maybe break into 9's. Unless some people like 1993EclipseGS won't rip me off, here on dsmtuners.com then I will have some finances to finish my project. Never buy from him, however he might sound sleek and very honest person, but he's not. That stuff I hate the most.

 

[nightspeed87]

anyone with the 2.1? Whats the advantage/benefit of that?
I thought that would be ideal since you could still rev high but maybe it gives a lot of torque still? I dont know, im just speculating. Im not going stroker any time soon so just asking questions for my knowledge.

 

[stockfornow]

Ok, then here soon I'll be picking up the 4G63 block and continuing that other thread. Thanks.

There are a couple threads in the Cylinder Head and Shortblock forum with good info, one of them might be in Stroker Tech.

 

[nightspeed87]

ok thanks

 

[chetvram]

Don't forget to factor in the price of a transmission that can shift at 9K+ RPM

 

[stockfornow]

As for the transmission I will have to get it rebuild anyway. I will do shep stage 2 or 3. We will see.
