I was planning on getting a turbo for my 93 prelude so I did some searches in the archive and most of the info I found said that its not good to turbo a prelude because ringlands, cyclinder walls, pistons, etc.

What you guys think ... should I spend money on a turbo? (planning on using stock internals with prolly 7psi) is this a good project to invest my time and money into? any help or advice would be nice.

You can do anything, with enough money.

 

eh don't believe any of that BS. the h22 is an awesome engine to turbo, your stock ringlands are fine for 7psi. most of the bad comments about the ringlands are from idiots who tried boosting 20 psi on their stock engine.

 

there is no "good engine" to turbo, some are better prepared than others.

if you prepare a block and install quality parts that work together and get it tuned correctly you will be fine.

some say a DSM block is sooo much better to boost, maybe, but it will blow out just as easily as an H22 block if it isnt prep'ed

just do your research and make sure a reputable tuning place does your work, dont just bolt it on a go.

 

should you turbo? a little more info is needed about you and your car before someone can answer this question specifically for your situation- like what is your car's condition and mileage? i suggest you should have a compression and leakdown tests done to help determine the condition of your motor.

but if you have to ask should you even spend your money on it - i'd have to say probably not right now - not till you have a well thought out plan and realize what that's going to require from you - more than just money (though it will require money, and a lot of it.... a lot).

but as mention above, if you do decide to boost it, tuning is key.

good luck.

 

I wouldn't waste the time and money to turbo it. It's a waste....and will only be headaches in the longrun.

By the time you are done "prepping" the motor, you've practically replaced all the internals.

dude thats a retarded statement. itll only cause headaches if you dont prep the engine right.

 

well my lude is stock with CAI and headers, has bout 110,000 miles. Engine runs great with no kinds of problem.

What if I just want a 7psi daily driver (but leave room for future upgrades ... prolly boost 12-15psi at the most) would i be fine at 7psi on stock internals? if so, for how long?

I was thinkin bout goin all motor but that cost too much and doesnt put out as much ponies as turbo for that price.

btw thanx for all the advice

one more thing ... where is a good place with a good rep. in So Cali to get a turbo car tuned with e-manage? or hondata?

there's no way to tell you long your motor will last with 7psi, or any psi for that matter, there are too many variables in play. again, tuning will make last longer and safer.

just buy a spare h22, build that one, get it tuned, etc and keep your current h22 as a spare

 

The main reason why people say h22a's are not so good to turbo is because the cylinder walls are made of FRM (Fiber Reinforced Metal) which is basically an aluminum-oxide alloy with carbon fibers in it, this makes the cylinder wall very strong and it also makes it lighter than a regular iron walled cylinder liner, the downside to this FRM cylinder wall is it is very abrasive (But not as abrasive as it was in the b21a1 in the 3rd gen preludes!) and forged aluminum pistons that are required for a good turbo setup are not compatible with the abrasive attributes of the FRM lining, so a special piston skirt coating is really needed to combat this, Search around for some good forged pistons for h22a's that claim they are compatible with FRM sleeves, I believe Endyn's Rollerwave pistons (made by Wiseco) claim to be FRM compatible....
Otherwise, if you plan on retaining the factory honda pistons, go ahead and boost away, just dont go too high otherwise your pistons might give way. A low pressure boost with conservative ignition timing would probably be key for an internally stock daily driven h22a.

 

Also if you do turbo make sure you get a good tune. Alot of the people that blew/blow there piston rings are running FMU's, AFC Hack and no tuning. Get Hondata or Uberdata.

 

thx for the info.

btw is 7psi coo for a daily driven h22a1? or should I go 6psi

 

Go 6 psi for reliablity its not like your going to drag or anything, right? I would always chose reliablity over speed, but thats just me. Do whatever sinks your boat!

lol .... well I just wanna go a little faster then I am now, but Im leaving room for future upgrade. Then go to the tracks.... its down the street from my house btw

I agree that you have to replace almost all internals, but dont agree its a waste of time. It can be headaches but if done right the first time it will save a lot of headaches. It's you not me. (not trying to start a debate or anything haha)

 

thx for all the input

 

i run 5 pounds of boost on a daily driven lude with a built bottom end. 9.0 compression. dont think ill be blowing anything inside my engine anytime soon. p.s. i tend to shift at less than 3k rpm to save gas i have big rig's passing me up!

 

Boost it to 8psi, add the proper fuel upgrades, get a nice EMS, and have it tuned to a tee.

You'll be fine if you follow those simple rules. I have plenty of background experience with these motors going turbo.... listen to those who have done it right instead of half-assed it or heard from one of their 'boyz.' End of discussion.
