Turbo on 95 vtec prelude

[SRV BOY]

What do I need to prepare my stock h22a motor to put on a turbo
with i guess 7-8psi. The compression ratio is 10:0:1. The only thing that has been done is I changed the intake system with a K&N cone filter and an arm.

Resleeve and get forged pistons.

Resleeved and Forged Pistons just for 7-8 psi...
From the answers i have gotten you need 455 injectors and a larger fuel pump. Along with that you need a piggy back ECU like hondata. With the things i've listed and a GOOD dyno tune you should be fine for 7-8 psi

For just 7-8 psi, you should get the larger injectors, piggy hondata S200, probably a high performance fuel pump just to keep ur a/f ratio not too high. Dyno tune if for sure. Also, Id susgest to get something like MSD's boost retard management i think its called. It retards ur timing 1°-3° per psi of boost. It will make sure detonation doesn't occur. The forged pistons and sleeves id only susgest if your gonna go to like 10 psi, cuz the compression is failrly low on the lude and the H22a block is strong enough to handle the 7-8 psi. Make sure your head is also in a fairly good condition, cuz thats where the most moving parts are and they'll be moving faster w/ a turbo. Lemme know how your set up goes w/ the 7-8 psi, im gonna turbo mine this summer.

wow, thats a lot i gotta do to get turbo man, how much do u think all that will cost me around?

[dbebesi]

why don't you look it up on some website's (DUH)

i just can't believe you are able to run a turbo with 38 pounds of boost on you engine already (he claims this in another thread-nos/turbo)

also.... fellow AF members, how do we go about banning someone?

Fairly low? A Prelude VTEC's compression is anything but low. It's the sole reason turbocharging a Prelude isn't the most popular thing to do.

What do you need to do to prepare for a turbocharger? Well first, you block needs to be resleeved, you'll want lower compression pistons. From what I hear, it's the ringlands that are the weakest thing in the h22a. You might want high performance rods and some head work is a probably good idea. And of course, fuel management. I highly recommend a standalone instead of a black box.

You don't HAVE to get stronger parts, but don't cry when your engine blows in a year. I believe the general consensus is that 7psi is a good number to stay at. You can also keep compression high if you want, but it'll probably lead you down the road for detonation.

You can buy a turbo kit, but it's better to build your own to get the parts that match your goals for the car, rather than having to later replace parts. Cheap turbo parts don't last very long. In the case of anything turbo, I do recommend going brand name.

Ya thats what I was trying to say, keep the boost low and the compression on lude will be able to handle it. Its still lower than some integra VTEC engines that you see some people putting like 7psi on. Its like this, u inflate a balloon too much, it pops. You put too much boost in ur cylinders, they will "pop". When there is too much pressure, it will want to go out the weakest area. So make sure your car is well tuned, especially the timing becuase if it is advanced too much, ull have serious detonation. I'd say if you have a tight budget, the re-sleeving is the best way to go. If you cant even afford that right away, get the low compression pistons. Problem is, its really annoying to have to put low comp pistons, sleeves, and rods in all at different times. Now I'm not too famillar on how to install sleeves, but I'm pretty sure u need a professional to do it. I think it involves heating ur block up so it expands. Rods and pistons are easier to install, in my mind.

If you want lightweight, forged pistons, you have to resleeve anyway.. might as well just do everything at once.

Ok so he is lieing then. Its ok, he dosent know much about the car anyway. Hell just be blown up on the side of the road along with all the other kids who add power to the car without knowing what they are doing.

[SRV BOY]

Ya thats what I was assuming, thanks for all the replies, I would hope that the motor would last me at least 2-3 years, but how accurate would you say your estimate of a year is? aces?

[AcesHigh]

It was a random number I threw out. There are alot of variables to it; how hard it's driven, how often, what kind of turbo, what boost... I think the number could range from a few months to a year or two. This is if you don't strengthen your internals.

If you do, your motor probably won't wear out.

[SRV BOY]

what if I were to just take the supercharger path?

[SRV BOY]

I also read some other forums and sites where they say they have blown their h22a motor when throwing a turbo on it, is it common blowing an h22a motor? If it will last me up to 3 years I will be happy

[dbebesi]

built the internals. do it right. or don't do it at all.
