Turbo for Lewd! (dependable??)

I have a 95 lewd with a H22A1 it has just about 140k miles on it, runs very strong (no smoking, knocking) and very well taken care of. I was thinking about putting a turbo on it right now, and run 6-8 lbs of boost. I want to know if done right will the engine keep on going for another 100k. Hoped out there has some kind experience with this kinda thing.

thanks

I dont have first hand experience with turbo-ing ludes, but ive heard that the h22 isnt good for turbos...If you want it to last on 6-8 pounds for 100k miles then youll have to put a nice set of rods, pistons, probably valve springs and valves, and maybe even a sleeve job. CAuse on stock internals youll never last for 100k.

Well I know that people say that H22a are not good for boosting because of the high compression ration (they were mostly made for all motor not forced induction) but if I upgrade the rods pistons and a valve job, (if smart lower compression ratio) I would think it would be easy to run run 10-12 lbs of boost daily, and 14-16 for the track. I know this is extremely hard to guestimate but if done right and not "too" abused how long you guys think it would last?

It will run fine and last 100K on low boost providing you have it tuned correctly. I have a buddy who is boosting 14 psi on a stock h22a (race gas) and making around 430whp. Not completley advisable, but it can be done. Boost doesn't hurt the motor, bad tunes do.

YEah man, with upgraded internals (dont forget headgasket!) and a lower comp ratio you can run it with that boost all day long. I was just saying the unrealiablility of it with stock internals. Build your motor right and it will last longer than it would in stock form!

Another question... Would the stock fuel system be alright with just 7-8 lbs of boost??

Nah.....youll more than likely need 440cc injectors and some form of fuel management. Maybe a new fuel pump.

Another Question... Do you guys know what kind of Turbo would work the best for my application... I've asked around most of em said T3 or the T3/T4 Hybrid not quite sure what would be better... Any ideas??

thanks

try a 67trim may be a t04e with a 67 trim you want some thing that flows at least 450lb/min.. tha will give you room to make at least 450hp, fuel mods, 255 in tank. adj, fuel pressure regulator, fuel rail to go with the 450cc+ injectors, and a s-afc to tune it also look into msd for ignation system..

bah...s-afc is poo poo for fuel management on a turbo car. after reading up on the hondata system a bit, i would get that over everything else if you still want a nice idling everyday street car.

Isnt the hondata system quite spendy... I understand putting a turbo on your car isnt exactly cheap but I am just lookin to get a some boost goin until I can afford the whole Shabang

yes engine management in general is very "spendy", and i would suggest a small turbo, i plan on using a garret gt28, the disco potato, it should work great on an h22

fuel management is the most vital part of a boosted car, and is often not addressed properly or sufficiently. dont cheap out on it.

hondata=$$
thats why i suggest the safc..

go all out, if you are gonna tune it and expect it to live you have to be able to manage every thing, timing, spark, fuel, air, boost, i'm planning on just forking over the $$$ for an AEM EMS, about $1000, but it's a do it yourself thing, tune it yourself on your computer, and make it work

hondata isnt that much doesnt s afc run like 450 same has hondata s200 with boost option so whats the problem he wont need a fuel pump or internales boosting so little and lowering the compression will make you spool slower dont lower the compression unless your gonna boost alot and build you whole motor

It all really depends. Detonation is the number one killer of a turbo-charged engine. My suggestion would be to replace your internals and lower the compression ratio to 9:1 or lower. Sure you can get away with 10:1 with good fuel management and good tuning but one bad batch of fuel will send your engine to the scrap yard. A good intercooler is always a good idea. Depending on how much boost you want to run you might want to upgrade the injectors and pump. For fuel management I would go with the Hondata, it might be expensive but they what they are doing. Personally I think the Apexi unit is crap and I would never buy it after looking into a ton of fuel management systems. Don't forget to have the car tuned, and tuned well. Not an afternoon on the dyno, but as long as it takes to get it right.

Play it safe and you will still have a fuel conservative, fast, reliable streetcar.

I agree 150% Keep it in tune and Keep the pre deationation out of the engine. Spark knock will kill any forcefed engine. Also SMC Alcohol injection Thats how I get 24 PSI on pump gas.

...Also SMC Alcohol injection ...

What exactly is alcohol injection? does it just add alcohol to the fuel mix or somethign? because i know like methanol and ethanol can increase your octane rating, but im just wondering about how the alcohol is delivered.

youngster, please use periods. it helps everyone understand what you are saying.

jermonsta, why not haltech?

haltech??? don't know much about haltech, but i'm not sure about AEM, it's the best way too do it but... i was looking at the prices and, about $2,000 just for the ems unit, so hondata might not be bad, i'll have to check out haltech, anything that controls everything is good, but don't go afc unless you are boosting real low prolly, does hondata control VTEC engagement????? what about Haltech???

Don't use Methanol!!! Denatured alcohol is alot ezer on metal parts. Methanol is cheaper but moe crrosive *sp* The alcohol is deliverd into the aircharge after the intercooler. It is pumped through nozzles. Whhen the alcohol hits the Hot air it evaporates lowering the tempature of the air dramitacly. (Same priceapal as A/C) Here is alike to the SMC system I run.

So its similar to nitrous injection in delivery? COuld you use denatured alcohol like you can buy at lowes or does it have to be a differnt grade or whatever?

I get mine at menards

haltech does look interesting, you might need two different modules but that might be ok,
