I know it is far from ideal but I have my reasons so hold off on the flames if possible. I'm just curious if the turbo @ 250whp would be a dog and the same question @ 300whp.

Combo will be stock LS motor, tubular log, 3" downpipe, etc.

I think if I ask Shodan anymore questions he will shoot me so I'm asking here lol. He has been an immense help thus far and I'm very appreciative!

Oh and .63 A/R

That's entirely too big for either of those power goals.

Stopsign32v

iTrader: (1)

I know that

At those power levels how will the turbo act though?

I dont think it would be "a dog" but agreed that its too big. You're in GT25 or GT28 territory.

I looked at the GT2860R and while it looks great the more I dug into old threads and the more I read the more I began to realize 2 things.

A)I will outgrow it
B)I will have traction problems from its aggressive spooling

The GT3071R is sitting right where I ultimately want to be once I decide to build a motor. But for now I want to have fun with the stock motor.

I don't think 300whp would be too far out of it's "fun zone". But then again I don't know near as much as you guys, I've just been reading reading reading and trying to soak up some knowledge.

You'll be outside of it's efficiency band. If you have a proper transmission, suspension, and tire setup, you won't have traction "problems". Yes, traction issues come with power - it's part of the world of speed - but for a modest 250-300, it's easily managed. Besides, Garrett turbos hold resale well. Either build to your final goal now with the GT30xx, or build to your 250-300 "I'll grow out of it" goal with a GT28xx, and when it comes time to upgrade, you'll have no problem reselling and upgrading.

That being said, have you thought about a 2871? It might be a fair compromise for fun now and fun later. At least, a better compromise than a 30xx would be.

I read everywhere that the 2871 is "mismatched". How true that is, I don't know.

The 3071 is a 300-400hp turbo so not sure how far out of efficiency it will be at 300. I don't want to buy a turbo now just to sell it later at a loss and get another. Another main reason I don't want to go that route is possibly not warrant...I plan to have Go-autoworks or Spoolin make my manifold/downpipe combination and if I design it around a 28 now I don't want to have to buy new exhaust parts when I go to the 3071. I'd rather just do it one time. I know it isn't an ideal idea, but is it really that bad?

GTX2871R has a mismatch, not the standard cast GT2871R

Stopsign32v

Ah in that case I might look back into the GT2871R or 2876.

Not for 400whp.. I've already told you why.

Stopsign32v

iTrader: (1)

Yes I've come to realize I might not hit that magical number. Still unsure...it seems @ 400whp a lot of things change.

I'd like to know what cars a 350whp RS Integra could hang with or beat.

LightningTeg

Thats like stock eaton cobra / c5z territory.

I edge out / am pretty close with pulley/exhaust/tune eatons @ 400whp.

You shouldnt have much traction problems unless you have some cheap tires.

Stopsign32v

That's slightly disappointing...so we are talking 115mph car territory?

TheShodan

iTrader: (14)

You're thinking specific drag race, and you shouldn't do that with this type of car. Lighteningteg is looking at this from both a realistic standpoint from his experience and a power-to-weight-ratio standpoint.

I don't see how a 2500lbs car capable of catching these vehicles are disappointing. its actually a LOT of power to control.

Stop thinking mph, and start thinking your driving ability. You can be in a 600whp and not catch any of those, if you don't adjust your thinking and your skill to this.

I understand completely Shodan but I'm actually not that bad of a driver and have had everything from this to a 700rwhp car. I'm just new to FWD and Hondas in general. I'm very good at controlling throttle though, so that's a plus lol.

TheShodan

iTrader: (14)

Its different driving. I'm not saying you're bad, I'm saying no matter how much you're used to 700rwhp. Its a different kind of power delivery and control ability on higher HP FWD setups that are using the same wheels to both turn AND provide grip.

But there's still no need to be disappointed when you have a bone stock block. Very few other manufacturers can make over 200% more power out of the factory with no modifications.

LightningTeg

Basically. Probably a bit faster. I trapped 112 around 300whp.

I would be weary about pushing a stock block past 350 anyway.

Stopsign32v

iTrader: (1)

That makes perfect sense and I'm sure torque steer will be something else to get used to! Not looking forward to that.

Crap, didn't know that.

Stock BLOCK can't handle more than 350 or the internals?

TheShodan

iTrader: (14)

Very risky at that point.. 300-320whp is the maximum reputable safe limits I've partially experienced on a Honda b-series for almost 20 years

Stopsign32v

Are we talking stock shortblock or are we talking the BLOCK even though it has forged internals

TheShodan

iTrader: (14)

A stock block is the oem engine block.

Anything with upgraded internals is obviously no longer "stock", right?

A stock sleeved block can hold about close to 500whp, with the upgraded internals.

No one would logically use aftermarket sleeves in a block with stock internals..


When we say a "stock block" we mean just that; no hidden meaning

Stopsign32v

iTrader: (1)

So what is the weak part of the stock block? The sleeves I assume? Sorry I know it sounds trivial to you guys but I'm used to cars that the actual block is the weak point, nothing you can do to it to make it stronger. So to me the stock block in this situation isn't a problem unless the block itself is the weak point and requires a different block to go past 350whp safely.
