turbo question for 5th gen
If i get a turbo, and wanted to run only 6psi on my 98.. how would it run without building up the engine? It will be my daily driver keep in mind..
Is there a high risk involved with running a stock prelude +6psi or is it reletivly safe. What else would be needed.. blow of valve and intercooler.. that it?(just 6psi) thanks

Let me start off by saying that I'm not a turbo expert or anything. Fritz or someone may be able to give you a much better answer but I'm going to try. First off, 6psi of boost sounds pretty moderate to me and it doesn't seem like you would have to do a lot of internal mods to get that to run good. Second off, are you planning on buying a kit or what? If you do buy a kit it should come with a blowoff valve, and maybe even an intercooler. Theoretically you don't have to have an intercooler with a turbo kit but you will definitely make more power if you do. An intercooler will cool off the air going into the engine, this will improve the turbo's overall efficiency and make more power. If I was you I would wait for the Greddy turbo kit to come out.

Ok thanks, im more concerned right now with what i NEED to do to keep the engine running good. I dont want to blow anything up after a couple months, or even years, thats why i want to stay with the low boost. I do plan on buying a kit, or maybe a custom one
thanks

I hear the DRAG turbo kits for the Prelude are pretty good.
If you're looking for reliability then why not go with a supercharger? It seems like the better choice for reliability and ease of configuration.

Well from what ive been told a turbo(?) would be better as a daily driver because its not constantly working as is a supercharger(?)
correct me if im wrong please, because at first i was looking to get a JRSC since i only want 6psi. Also, anyone know what kind of gains i would get with 6psi boost? im guessing around 40-60 hp?

Actually the Jackson Racing supercharger isn't "on" all the time. It actually has a bypass system that virtually disengages it according to the throttle position. :cyclops:

at 6 psi, you could gain about 40-60hp at the wheels if tuned properly.
if you want a complete list of parts required for turbo, try here: http://store.importparts.com/cgi-bin...11.storefront/ it's a complete list of parts that comes with a drag system.

drift are you still making custom turbos? Are you running one?

yes, i do custom turbo kits, and yes, i am running one based on the Garrett/AiResearch T3, .42A/R compressor, .48A/R exhaust. they're not a drop in installation. these are DIY kits, but come with everything you need to make it work. the kit is also custom tailored (and price adjusted accordingly) to meet your needs... in my case, mine is set up for low rpm boost, 6-9psi, for autocrossing, with all safety features to prevent breakage since this is my daily driver car with higher than stock compression. hit me up on aim for details if you wish.

true on the s/c... they are better for lowend power increase... and a turbo is still spinning all the time, b/c it is driven by exh gas...
drift is the guy to talk to though... but... anywhere up to 8 or so psi on a stock motor should not be a prob... but i would again, talk to drift to find out what you need... also... the intercooler most likely is not necessary, but it will help in making power... the same car with an intercooler makes substantially more hp with it than without... but it also increases compression, making it a good time to switch pistons, etc... and im babbling...

everything was goin good til this part. intercooler lowers charge air temps. like with a CAI, colder air is denser air, and harnesses more power per stroke. non-intercooled systems are more prone to detonation, especially in warmer climates since the air is heated when compressed, which is especially bad when it takes in hot air in the first place. the intercooler would bring it down to acceptable levels. hot air can cause leanout detonation. not a good thing. intake charge temps can be monitored by watching your exhaust gas temps... hotter intake air will cause exhaust temps to also rise.

Drift, would a turbo kit bring down the life span on my engine with stock internals if i run the right psi of boost? I have been told that turbos arnt good for a daily drivers and that a jrsc would be the better choice.

i think that its going to decrease the life span no matter what psi you go with because your straining the engine more.. i could be wrong i dont know. The reason you were probably recommended a JRSC was because it does run low boost, so its not bad running on stock internals. You can run a turbo low boost also, and not have to worry about changing the belts as often as you need to with a JRSC
Ive been contemplating this in my head for awhile now and ive chosen the turbo. Im going to run on stock internals (for awhile anyways) and only run 6psi, and keep it as a daily driver.

that sums it up. boost is boost, no matter how you cut it. low amounts of boost will not destroy the car, but running it harder/racing it will. the boost can cause seals to go a bit faster, but i've seen turbo cars run for over 100k miles before needing a rebuild. best to guess you may lose 20,000 miles off the life of your car... instead of 200,000 miles for the first rebuild, maybe you'll get 180,000 miles The bottom line is TUNING... you could have 6 or 60psi of boost. if the fuel curve is not optimized, you'll blow something up, one of which being your wallet

what i meant is that you can run w/o an intercooler on stock internals, but adding one in means higher compression with cooler air... which could cause problems... but it also adds tons of power...
on most of the buildups i have seen, once you add a cooler on there, it usually means you want to up the boost, which means its time to go to low comp pistons...
