a 2.3 mated to evo green, bbk, or htagreen is a match made in heaven for street fun

 

Sorry, my head is gone by Friday with my job eating away my brain cells. What turbo are you using? FP Red?

Do you already have your 2.3 or are in the process of building one? The problem with the smaller turbos (green, BBK, HTAGreen) and the 2.3 is above 6.5k the turbo would be hurting, unless you were keeping the power level under 450 DJ. The instant spool is really nice on the smaller turbos but you don't want your powerband to be dead above 6.5k... I think having a 2.3 or 2.4 you really need a min of a BBK-B, Red, or Black.

For a staight up street car I think the BBK-B would be the best bet with great spool and still having the power potential up top Great turbo Chad

I'm seriously thinking about staying with the stock VIII turbo for about a year before buying a larger. If I find a nice price on a used FP Red, I'll entertain the offer. JMS in San Antonio is doing my 2.3L build. I'm familiar with the 6.5K "sweet spot" but I typically shift at 7.2-7.5 during spirited driving. I'm really interested to see what 500whp feels like as I was previously tuned at 394whp and 411wtq. Sorry for the mini jack...

 

If I can find a nice FP Green (non-HTA) that would be great to use in the short term.

 

My good friend has a Brand new FP Red 84mm for 1500 shipped and it comes with the new FP oil line. Ended up buying a Black instead. lmk

you give lots advice on very little experience.

I have actually driven stroker engines with the following turbos
14b, 16g, 20g, 25g, 57trim, 50trim, FPred, 35r, HTA3582, HTA3586, and 67mm. and there are likely some that I forgot.

I absolutely loved the 2.3 20g. lifted the front end of the car all over the place. cant tell you how many asked if car had nitrous. it did not lay down till over 7000rpm. it had right here right now powerband. no lines no waiting. was the most fun I have had in a street car yet. but that is just my opinion from my limited view point. take it for what its worth.

I have the hta green on 2.0 in my evo 1. felt laggy for my tastes. I am building a 2.3 for it now.

Very true, one thing that many people don't consider many times is the area you live in. Take my city, not that big and freeways are not very long, and surrounded by mountains. This is not the ideal place for a gt35R set up for top end, you will never get to use it all, and a huge NO NO in tight mountain corners. The environment you in plays into how to set up a car also.

 

After this past week my opinion has changed on small turbo s / stroker combos

My rod went through the block


I was running around 35psi and floored it in 5th from a very low rpm -- engine went out right around peak torque..

 

Awesome to read. And you're talking about the old school 20G turbo, right? I'm actually considering going with a ported stock IX turbo on E85 if I can't get the funds to line up right.

This is so true. I'm in Sierra Vista (southern Arizona) and the nearest freeway I-10 is about 30 miles away. There are NO "real" highways within the city either. BUT, there are plenty of nice stretches (3/4 of a mile) between stoplights and even a few short straights all over the place. Traffic is always low around here (even during rush hour periods). This is my thinking considering that once something with a larger turbo catches up, based on the environment, the "sprint" will be over and they'll be in catch up mode the entire time.

 

That is very unfortunate. I would say that it was unwise and I'd ask what you were doing in the process.

What are your plans for your 2.3L as I could probably use most of those parts for my 2.3L build. Not trying to sound funny or sarcastic but the EVO world is built on the loss of others as I threw a rod in my stock 2.0L on 26DEC only after one week of having it tuned from returning from Iraq. I sent you a parts lists via PM for you to look at.

Again, sorry to hear about your engine.

 

thats a result of poor tuning. dont blame the parts. making low rpm torque is not hard on parts by mechanical definitions. high rpm torque is hard on parts. I.E. 300tq at 8000 rpm is harder on parts than 500tq at 4000rpm.

 

What was you hp on your 2.3L 20G?

OP what HP are you looking at getting with your 2.3L 20G

This statement just killed my theory (concern) about a smaller turbo with a stroked engine. Since 500whp and 450-500wtq is my goal I was always concerned about having to beef up my drivetrain. I'll spend 98% of my time on the street. Because of the extra displacement and smaller turbo (stock IX), the drivetrain will be safe if I'm in the 450-500wtq region from (let's say) a 25-40MPH roll. I do not want to have to worry about my drivetrain after spending $ on having this 2.3L engine built. That would be a morale killer!

Your drivetrain is fine with that much tq on a roll. The only time you will run into a problem is if you start launching your car. Your t-case will be the first to go, and it won't take long!
