Want to turbocharge
Hey guys I'm Shawn, and I'm new to the forums. I've been wanting to slap a turbo on my car for years now but haven't had the money. Well, I recently got a good paying job, so I figured Id make my dreams come true while the money is still decent. I own 2 integras, an LS and a GSR that's totaled at the moment. Bought the LS to swap my GSR motor into. The donor LS body is extremely clean with no rust on it.Anyways, I've done a good amount of research lately on what it would take to turbocharge my car. And I think now I have more questions that are unanswered than before. Ive done a lot of reading, maybe not enough though. So let me explain what I want to do here.
My objective: I want to take my car out once every few months on the streets and do the occasional quarter mile in it. NOT a daily, but also not a full on race car. It will be driven pretty hard when it is driven though. I want power steering (I think) and definitely would like to keep A/C for hot summer days. Since this car is my baby, I'm probably going to keep it for the next 20 years and I'm looking for ultimate reliability, no shortcuts.
My power goals: ~400-450whp
My solution to get there: sleeved block, connecting rods, connecting rod bolts, pistons, ported and polished head, valves, retainers, and springs, bigger injectors, e85 conversion, engine management, type r oil pump, new water pump, new seals all the way around. Probably forgetting some things as well. A friend I know claims the stock sleeves in a b18c1 can hold 700hp on the right fuel and tune. I've read 500 on here. So, lots of inconsistencies and hearsay. What I want to know is, am I going way overkill for the project at hand?
I found a Sheepey built top mount manifold thats compatible with PS and A/C. The only problem is it only comes in a Precision or Tial flange style. So, I went and looked at turbos and mostly what I see is T3/T4 flange. I'd like a reputable brand turbocharger in the car, something that I can achieve my power goals with and still be able to spool somewhat quickly for street driving. What turbo can I use to get me there? .63 A/R or .86 A/R? What size turbine wheel? 76mm?
Also, I've read forums that say you don't need to worry about sleeving the block, the stock cams are fine, the pistons are fine, etc.. but I've also read it's only a matter of time before something goes horribly wrong making that kind of power on stock internals. I've read about detonation and how important it is to get it properly tuned and run the right fuel.. I'm thinking of running e85. I probably will be running Hondata s300 in the vehicle too, and taking it to a tuner to get it tuned and dyno'ed.
So anyways, I'm very confused on where to start my build. I think the best first step is the fact that I've identified what I want to do with the car aND keep my PS and A/C. So, I have the manifold picked out. But now the questions are:
what size turbo to run?
what kind of internals am I going to need to make the engine bulletproof?
what compression pistons should I be looking for?
Are rods rated for 275hp/cylinder better in terms of not stretching or snapping than rods rated for 175/cylinder? Especially since the desired goals are expected to be 100-115hp/cylinder?
