Hey guys, my name is randy, and im considering buying a 94 prelude from a co-worker.

The guy bought it as his first car, has some basic boltons (AEM CAI, DC header, some cat-back exhaust, springs and shocks)

Well i already have a car, a 1992 miata with a lot of suspension work, and a mostly stock motor. I also have a 2002 GSX-R 750, all stock.

I think if i got this prelude, id want to turbo it i think. I found a website called turbo-kits.com but it is very vague on the contents and gains of the turbo kits. Ive considered peicing together a turbo kit of my own, but i dont know much about turbos.

I know they require a lot more maintnance than stock or lightly modded n/a setups. I know they give good power in the mid/hi range of the powerband. I guess i know about as much as any noob, but im not much of a motor guy. I really like the way it drives, i think its a nice mix between luxury and performance.

I think id be happy with 300-350 whp. I dont want to modify the internals just yet, but i have hard that there are 'turbo' head gaskets. They are strong to withstand the excesive pressure of boost, and they are a little taller than stock to drop the compression ratio, im fine with that if i need to for that power.

I know my way around a car pretty good, im a diesel technician by trade, but ive done all the work on my miata and my fiance's celica (she has some boltons and suspension work)

so what do you think? can i do 300-350whp on stock internals? I think id run around 8 psi (mabye 9, i think 10 is pushing it on stock internals from what ive read)

About the car... its a 95 prelude VTEC. He said it has about 230-240 bhp now with the boltons. It has just under 100k miles. I know he raced it, because ive raced him. He keeps up the maintnance pretty good, he said he uses that 5000 mile oil, and usually changed it on time. The interiror is MINT. no tears or anything anywhere. He doesnt smoke, and its never been in an accident. He said he got rear ended at about 5-10 mph, but the subframe was untouched. He wants 4000 for it with the mods, or 3500 back to stock, and without the 17" no name wheels.

What do you think? what should i do turbo wise? a kit or build one myself? thanks.

I say go for it. about turbo-kit.com... I would recomend the rev-hard kit. it comes with everything. I seriously dought that you'll be anywhere near 350whp with just the turbo pushing 8psi. Also I don't think he is make 230-240 hp to the ground. Have you ever seen a h22 dyno graph before? With I/E/H etc they are more like in the range of 150-180whp depending on the dynoe. With intake header and vafcII I was at 175whp and 136ft/tq.

Besides that I say go for it. If you go boosted you can tune it to run on 10psi but I wouldn't go much higher than that with stock internals.

heads up for you. a 95 usdm vtec gives 190. adding 40 to 50 horses with a cai, header, and catback is a little far fetched imho. :)

ok, do you guys suggest buying a kit or peicing one together?

if i ran open downpipe would i be able to get ~300hp?

also, there is no revhard kit for the 4th generation preludes on turbo-kits.com

that's not even a little far fetched..that's impossible. The amount of work it takes for people to hit near 200 at the wheels is insane for the pretty much minimal gains you're getting when compared to what you could have with other cars for far less money.

I honestly think you're rushing things and you could end up paying more later if you don't do things right from the start. Why don't you take your time and build the engine first before doing any boosting? The stock engine won't last long even if you decide to run low boost 6,7,8 and 10 forget about it that's an even shorter engine life:eek: . Then after that what? build the engine which it was what you should done in the first place, to me it doesn't make sense to have fun boosted when I know it won't be for long and be worry all the time while driving it hard. I recently purchased my 94 vtec and I'm in the same boat as you, I want to go with boost, but I will take my time and build the stoutest angine I can get. Just my 2 cents:D

To get optimum performance from a turbo, sell the H22 and get the H23. As stated above, dont go too high with the psi with stock intermals. Good luck with the Lude!

h23s are way more responsive to bolt ons then h22s.....i would never turbo an h22.....maybe a frankenstein....but not h22 block and head

your right! I just went on the site and its only for the fifth gen preludes. Sorry. I haven't been on that site in a while. If you want to make power, you have to pay to play. h22's don't hold boost really well on stock internals man. I'm trying to tell my friend the same thing.

+1..

The H23 is an excellent setup for a turbo.

I also recommend piecing a kit together. It's a much better alternative to those "Holy Moly" kits.

I wrote a good sized post on this on H-Forums, but I'll find it later.

Also -- upgrading stock internals is almost a must. Even if you're pushing "only" 300hp, it's better to be on the safe side. Blowing something up is going to be expensive.

Thats not to mention the extra power gains you get from building the engine alone. I'd also reccomend building your own kit. In the end, it's often times less expensive as well.

Oh yeah, its half as expesnive as a GReddy/Garrett (do they make kits?)/HKS kit, but.. you might even be able to pull it off for less than the XS power kit.

GReddy T3/T4 - $300

Godspeed FMIC - $190

OBX turbo manifold - $300

Wastegate + BOV - $70-80


That's what is included.. but not everything you need.

yea that sounds great man...I've been eyeing a couple of turbos since I got my 94' Si...I found a site that is relatively cheaper and has the whole setup...

havent heard ne word on it, but sounds okay to me...I have a long way to go before I can even think about droppin in a turbo...
