ok, im planning on gettin the Drag turbo kit for my 2001 Prelude base. But everywhere i turn, i hear "Dont do it, dont do it" i would like to kn0w why the "F$%K" not...i mean, ok so i dont have the $6-$7 g's to build my motor to be in a magazine, but i just simply want a bo0sted 'Lude...i mean am i playin' with fire when it comes to bo0sting this motor...or will the kit under 9psi's and proper tuning be fine, for the stock internals...IM LO0KING FOR THE BADS OF TURBO-ING THE H22A4...Would u do it???? What would happen in the long run in terms of bad things???

 

Is this going to be a daily driver car?? Do you have a flexible budget for when the engine fails/needs repairs?? Are you willing to have down time for when it does need repairs?? Do you know a good tuner??

These are all the questions you need to answer

I have said it before..I will say it again...Preludes were NEVER meant to be turboed. You want a fast car.....then you bought the wrong car. The Prelude is a great car...but it was never meant to be turboed.

Good luck.

lots of info here

 

i searched that , but everyone always gets off topic...i mean im lo0kin for an answer here not everyones opinon on what manifold they need or what whp they got...and for the above post, i do have a go0d tuner and yea i got down time, but what problems tend to happen when you turbo the h22a when bo0sting >9 psi. i mean if im going to be putting in $1000 a month they obviously i cant be doing that. what problems do you kn0w of, off the top of your head that are going to happen.

Thanks for the replies!

 

well, from my research for getting my turbo together. it seems that as long as your keep the boost levels below 7 psi and you make sure you have good fuel management you should not have to many major problems arise.

The main thing that seems to happen is the fuel system leans out which causes detonation. that in conjunction with the higher cylinder pressers can cause the weak ring lands to break.

from what i read it seems that if you keep up on maintenance, oil changes and what not more often, and you dont raise the boost it should be possible to have a turbo for a while with out problems.

This is only my opinion from what i have read, i do no claim to be a turbo guru. If others have more information or want to correct my info it is appreciated.

 

Problems for now??? so i should expect pr0blems later on>?

 

you might, remember what was stated above "preludes were never ment to be turboed." If i were you I would save your money and build ur h22. Your car won't break down as much and be 4x as realiable (if your still running under 10). I saw a poll with stock internals running 6 psi and only a few made it passed 20k without having to replace anything.

 

If you want to go turbo buy the greddy, better quality. As far as turbo problems go, this goes for ANY honda engine they were not designed to accept boost, and you have to build the internals. When a car comes factory with a turbo the block was made to handle boost, the cylinder head dissapates heat better, pistons and piston rings were made for boost. You can boost a prelude on stock internals up to 10 psi at the track only, anything over 7 psi needs intercooler. 7 psi for daily driver. If you want reliabilty go supercharger, you don't even come close to the power of a turbo and it is more expensive but it is more reliable. So in the end your turbo honda engine will end up costing you about 6-7K with intercooler, turbo, internals.

 

So even if i stay @ 6-7psi and with a front mount interco0ler...your still saying hands down to the turbo kit? i have an explorer as well so it wouldnt be driven everyday...also to the reply about having to replace things...what did hey have to replace?

That isnt true. What do you have to back up that claim? I know quite a few people who have had problems with poor quality with greddy honda kits. I would rather go with Drag or FMAX if it was up to me.

You can say that about any NA engine, not just Honda. Again, where are you getting these #s? "up to 10psi" etc, I know someone turbo's an h22a to 10psi and the crankshaft itself broke... So you cant tune a stock internal'd h22a turbo to run 11psi? ever? its never been done?

Why track only? The car somehow knows the difference between accelerating down the freeway at 10psi than it does on the track?

Thats not true at all. Jackson supercharged honda's are just as unreliable as any turbocharged honda

These absolute values of __psi, __ much money its not beneficial to throw around hard numbers like that.

This all sounds like a bunch of internet message board myths and rumors that have been around for years.

 

well what do you think nick???stock internals under 9psi's or am i setting myself up for disaster? I REALLY need an honest answer please...

 

if you want to run stock internals, use a thicker head gasket to drop the comp. ratio, get a standalone ecu, use proper injector/fuel pump size, and dyno tune. or if you want to be really safe, spend the 2k on sleeves and forged internals.

yep. do it right and save for the rebuild. if you cant afford a rebuild then you cant afford to turbo IMHO. turbo is expensive to do, maintain, and fix. budget boost is BS. once again this is all IMHO.

I have seen these kits side by side and I prefer the greddy. just as you stated that is what you think, a personal opinion. I never said those brands were bad. It is simply my opinion the greddy is better quality. And it is not up to you, it is up to the guy who posted this.

You can say that about any NA engine, not just Honda. Again, where are you getting these #s? "up to 10psi" etc, I know someone turbo's an h22a to 10psi and the crankshaft itself broke... So you cant tune a stock internal'd h22a turbo to run 11psi? ever? its never been done?

I do believe he was asking about a honda engine in particular so there would be no need to mention other NA engines,
Where did I say 11 psi?????? I never said it would last at 10 psi let alone 11 psi where ever you got that number from?


Why track only? The car somehow knows the difference between accelerating down the freeway at 10psi than it does on the track?


obviously you are not a drag racer, that is where 10 psi comes in. It is all about pushing it for those extra tenths of a second. I have seen preludes blow the motor at 10 psi, and I have seen just the opposite. Keep in mind that you do not run at 10 psi daily, let alone the freeway, and requires extensive tuning to run 10psi at the track. Again factors of engine conditions come into play as well as tuning, so the car is not running lean and has enough fuel as to not dentonate. Your statement is moronic and uncalled for as well as completely off subject.

This statement is an example of putting your foot in your mouth, Superchargers usaully are not operated over 6-7si, keep in mind I said the word USAULLY.Because superchargers make power differently than turbos and not as much they are more reliable, and GENERALLY considered better for daily driver where ultimate power is not desired, but more power is desired.There will always be people for supercharging/Turbocharging and against, It is up to people's own personl preference as to what thier fancy is. I never threw a hard number around, it was a generalized number. A hard number would be if I claimed it WOULD cost such and such for this turbo. The reason for the intercooler over 7 psi is because honda engines run a little hot without, and because the intercooler add considerable amount of power due to cooler ambient temps. Again This post was asking about how much it would cost, and side affects to turbocharging, not insipid attempts at slander that are completely off subject. I chalk this knowledge up to the fact of experience at the track and working on cars where POWER is the number one goal. No where did he say that this was going to be daily driven, as well. If you want to post you personal views and attack other people's them Nick M start your own post.


Mr shakes has the right idea, if you want alot of power save for the rebuild. You can budget boost, but what is the piont. Forced induction requires money and time for tuning and maintenece, if you do not have either don't mess with it.

 

ok, well the last post was somewhat what im lo0kin for...all im saying is, i kn0w i will have to maintain the car, and yes money into the car after i turbo it is essential...but you all make it seem as if i turbo my prelude that im going to drive off my drive way and the motor is going to explode...i kn0w it requires maintainence...but if i take care of it is it a reasonable car to turbo...all i want is a drag kit @ 7psi and power range over 230whp...anyone else want to put there input on here...

 

From what I have been reading around in different places, the number one thing that is mentioned always is TUNING! If the car is tuned right with the right stuff under the hood, you got a reliable daily driver. I think a tuned intercooled turbo is more reliable than a supercharger.
This is really good info though, I hope more people give their thoughts!

 

WHere is there a go0d online place to buy a turbo kit....so far i think im going to go with modacar.com but is there n-e-where else?

 

I'm running 9 PSI on stock internals with a Revhard T3T04e... I am using the missing link check valve and Vortech Rising rate fuel pressure regulator that came with the kit, and an APEXi VAFC to fine-tune the fuel.

I have been doing compression tests weekly since the install with no changes in compression. The "weakest link" in a h22 are the ring landings. If you start loosing oil/smoking or see a compression loss, they're probobally gone.

 

Oh yeah, about the supercharger mentioned above, I've had both... The jackson racing is probobally more reliable than MOST turbo kits due to the sealed lubrication system, computer controlled boost dependant timing retard, and overall quality of the kit. JRSC's are basically OEM grade stuff, but my turbo makes more power

I myself don't like the extra injectors and controller in the intake pipe on the FMAX, but the Drag, Greddy, and Revhard are all about the same with the exception of the greddy having a smaller turbo, internal wastegate, and lack of an intercooler with the base kit.

What made up my mind with Revhard? Price! $2850.00 gets you a good T3T04E .60-.63 turbo, 24x8x3 intercooler, nice piping, Turbosmart external wastegate, Vortech blow-off valve, Vortech RFPR, and a Missing Link check valve.

 

so far no problems with your rev hard i assume...so i would be ok then with the drag kit and some go0d tuning??? i cant wait to get the kit, but i still need to save a little more$$$! WHat other mods do you have? are u using the stock clutch/flywheel? and how was the install on the rev hard kit???i would love to see some pics...thanx for the info

 

I installed a ACT HD pressure plate and Street/Strip disk when I installed the JRSC last year. For exhaust, I am running a 2.5" custom downpipe to a Greddy PE catback, no cat, TurboXS boost controller, HKS turbo timer, APEXi VAFC.

The install went okay, only a few minor details to iron out. If it's a first time turbo install, beware... No instructions are provided with the kit. I will post pics soon...
