to all the turbo'd h22 ludes out there

i was just wondering how much boost you run with stock internals and with out sleeves i've heard you can run 5-6 psi comfortably with a daily driver, but i've also seem some people running 8+ psi with stock internal's and no sleeves

i heard 6 psi, i think im getting a greddy turbo soon

H series motors are strong, you could, and I stress could, push 6psi without changing the internals, but that begs the question why? Engines and turbos are expensive, why would you risk the life of your enging by pushing it past its safe limits? If your going to spend the money, save a little bit longer and buy the internals and lower the compresion, that way your safe and you can increase your boost later down the road. IMO the 60ish horsepower gained form a turbo at low boost isn't worth the risk.

its not a risk, 6psi on a stock engine is fine, i have heard that from a lot of different people

I agree i've heard from people with b18c1 swaps run 6psi and have no problems, correct me if im wrong but arent the compression ratio's of a b18c1 and a h22a the same? as for building internals first, i ask this question becuase on Preludeonline, there is a guy selling a Greddy turbo kit for 2,300 which is just in my range.

yea i just picked up a greddy turbo kit for a great price, whats the site for prelude online?

about 6-8psi 10 being dangerous

preludeonline.com :laugh: freat forum best prelude one around in my opinion i think a few members here are members there as well like Del ayways the guy was selling a used greddy kit for 2,300. My name on Po.com is the1986 by the way

So do you know if your gonna go turbo, on all stock internals. If you do tell me how it goes.

Im running a custom t3/t04e turbo kit and its running 6psi on stock internals. Everything is very safe and reliable. You can go up to 8psi safely but even that is pushing it.....6psi would be a safe place to stay until you buy internals. And I have been running this setup for 7 months now and have had no problems.

well im probably gonn go turbo on all stock internals, but it will probably be a little later, im about to pick up a set of LE37's for 1,500 so itll be atleast a month or so but ill keep you updated when i do

what kind of turbo timer are you using?

what cars have you guys raced with the turbos? how did it go?

I use the A'pexi turbo timer.

I have raced many a Civic, Eclipse, Mustang, and Camaro. I have beat every Civic, Eclipse, and Camaro I have ran against. There was a Mustang that smoked me....I later found out he had about $10000 in the motor and was running nitrous on top of that so I had no chance.

Hey guys, this is my first post, I have a 92 Lude Si, mods include: 17in wheels and tires, AEM Cold air intake, Fuel Rail, Brembo Brakes, B&M Short throw Shifter, Centerforce Stage 2 clutch, Apex'i Stainless Exhaust, Integra Type R shift knob and boot. Ground Wire kit, Hose kit. My questions is, when u say "redue internals" What exactly does that entail? My car has 110,000 miles on it but i wanna keep the motor. I contemplaiting swaping to a VTec or I would like to swap out the internals, what would be the price difference? What does "Internals" mean, what would all the internals consist of? COuld somebody E-mail me with a list? Thanks!!!!

i would like to know also

internals are RODS, PISTONS, and CAMSHAFTS. When you replace the Camshafts, which isnt necessary to replace, you usually need to replace the stock valve train. This consists of INTAKE and EXHAUST VALVES, VALVE SPRINGS, and SPRING RETAINERS. These would be enough to run higher boost very safely and would help in adding power as well. If you are wanting to run high boost though you would definently want to SLEEVE your block. Darton makes good sleeves and there are others out there as well. This will require machine work to be done to you block if you choose to sleeve you block as well. I don't know everything, but if any other question let me know and I will try to help you out as best I can.

if u get forged pistons, you have to sleeve your block. :grinno:

what is sleeving?

sleeves strengthen the cylinder walls because the block is made out of aluminum which is weak. You install sleeves which are made of a stronger metal like iron and it makes the cylinder walls able to withstand higher pressures.
