I have a '95 Integra GSR. I bought the car w/o drivetrain. My original goal was to put a stock ls motor and a T3/T4e and run about 10-12 psi on pump gas. I'm planning on running dsm 450cc with the hack or smc. I figured that if I blow up the motor (given that the sharpnel doesn't get into the turbo), it's just a $3-400 dollar replacement for the longblock.

I've recently come up on a good deal for a set of Wiseco pistons. If I get pistons, I might as well get a set of Eagle rods too. However, I'm probably not going to get the block resleeved (too much $$ at this point). As you can see, this project would snowball into much more money that I anticipated (kind of a lesson I learnt the first time I turbo'ed my car).

I know it's all in the tunning. Provided that the a/f ratio and timing is in good accord, how much power could 450cc injectors, forged pistons/rods, stock sleeve handle on a daily basis? Is the sleeve the weakest link in this setup?

I've read that Inline pro is making crazy power on stock block (except for hg). Are the pistons the weakest link in a stock block?

In short...I'm poor and could only handle replacing a stock longblock if my current motor blows. If I get forged pistons/rods, I would be quite upset if the bottom end goes in less than a year. For fuel management, 450cc and a hack solution is the most I can afford now. Would the stock internals be able to maximize and come close to the limitations of the 450cc?

Is a low compression hg necessary for the LS (since it's only 9.2:1)?
I just want to get the most economical performance (is there such a thing?).

I'm probably going to run a gsr or b16 tranny. I just want 12's on drag radial or slick but with full interior. I'm pretty close to that in my NA Crx ( but w/o the comforts) and I'd like the new car to be quicker or as quick.

Sorry for asking so many questions, please add any positive inputs if possible. Thanks.

 

Inline Pro do sound great most of those guys will be using better tuning then just the hack!! You perhaps should look at http://www.hondata.com Inlinepro gasket then worry about the rods failing as they are the weakest link..

 

Thanks.

Would I be able to run 12psi with the hack and stock internals? I'm not too sure about the hondata fundage right now.

 

12psi and the hack I wouldn't.....with hondata and stock internals only at the track yes. Have you actually priced it up hondata is not that much more the and afc + injectors+ resistors.... If you want to run a decent amount of boost on standard internals this is the way to go.

 

This idea, in my opinion, is the BEST route to follow for street cars. However, I would use a B18C or B16A instead of the B18B...but either way, you have the idea right. There is no need to build the motor, you can easily sustain 12-14psi on a T3/T04E on those motors, given you have ample fuel and tuning. I ran for 2 years and elected to build out of a lack of knowledge. Had I known better, I would have just waited for my stock motor to go, and drop another shortblock on for $300. Much less expensive than building it, and even when you build it...who cares, what the **** good is a 500hp FF car on the street anyway?

I know exactly what you mean by the snowball effect. I say get a stock block, which ever you choose will be fine, and get a hondata or some standalone to use. The headgasket is a waste imo, especially for $300. Just don't get too crazy with the boost, and the motor will hold together fine. 12's on street tires should be easily achievable w/ a stock motor, ls, gsr, or b16a.

defentially get a hondata, its ~ $100 more for s100 w/boost, vs v-afc and no way to adjust timing, and it hides boost instead of reading it...talk to 2kteg for a good hook-up on the hondata system...

and i say get the forged internals, you can then safely boost, and NOT blow your engine, im not to sure about b-series but i would say that the sleeves would be the weak lionk, so if they go, get another bare block and throw this setup in that

 

my LS is tuned to 13psi, its a stock motor but im running hondata. if the vafc set up is done right 11psi should be fine, just make sure u retard ur distributor back 3deg or so.

 

if you dont get hondata and just buy an smc w/ 450 injectors as long as you retard the timing on the distributor you should be fine. as for the weakest link, the pistons definitely are in a b-series motor. if you cant afford sleeves you could always go block gaurd, just make sure its welded in and the coolant passages line up. str has a good one.

 

What's the best deal for Hondata (probably the 2b). I live pretty close to VaporTrail, so I guess I have someone to tune it.

I was leaning towards the AFC hack b/c a unit could be found used for about $200-250. But I guess the cheaper solution is usually not the better...

Hondata + stock internals + 450cc= 12 psi on 93 octane w/o problems? Sounds good guys?

 

... with this setup... what would be some expected numbers?... i know it is hard to say since every engine is different... i am just curious on some estimated performance numbers... like hp, tq, et... thanks...

 

yeh thats basically my set up. no problems at all. afc hack wont let u control timing, hondata is worth it.

 

... and 274whp/ 237ft/lbs...
... what turbo are you running?...
