Swap or Boost

[Mario]

God I am so tired of going back and forth, these options are just killing me. :D

Here's what it comes down to: someone is finally making CORRECT motor mounts to do an h22a into the 88-91 Prelude. That means that the swap is possible over a weekend. Now, here's my dillema. I can either turbo, or swap:

Turbo: 7psi on a T3, apprx. 200whp, Hondata tuned, 440cc DSM Injectors, BOV, Tial WG, etc. $3000

H22A: N/A (for now), apprx. 160whp to start, intake and exhaust to start, hopefully done for $3k (motor = $2100 | mounts = less than $500 | custom 250whp axles = $400 | wiring = $100)... I could then either turbo that, or just stay N/A.

What are your thoughts, pros, cons, on both?

i think you can get that kit for a little cheaper than $3K, especially if ou are piecing it together. My vote would be for the boost.

Yes, I am piecing it out together:

JDM B20A Motor = $400 from HMO (no way am I gonna boost on a 177k mile engine)
Turbonetics T3 = ~$500-$600
Manifold = $225
30x6x2 FMIC = $300 eBay
Downpipe = $200
IC Piping = $200
Tial 38mm Wastegate = $200
Walbro 255lph = $100
Oil Stuff = $140

What would be some good fuel management stuff for a mild turbo app like this? I don't plan on running more than 7psi tuned.

The intercooler piping with silicone couplers and stainless steel clamps
I can get for $200, or with $230 high temperature coating.

The downpipe would be $180 without flexpipe, or $210 with flexpipe.
The oil line kit (with all stainless / aluminum fittings and steel briaded
lines, gaurnetteed to never break) would be $140

Intercooler piping = mandrel bent? Same with downpipe?

I may pick you up on that then... :)

Mandrel bent

get some DSM 450CC injectors and a nice FMU. You can always find good deals on turbos, intercoolers, wastegates, BOV's etc on ebay, so im sure you could spend about $2K instead of 3 if you look hard enough.

[Mario]

Ok cool, I'll contact you once I am ready to get that stuff made. :) So any more ideas would be great, whether h22a or boost.. especially for engine-management for OBD-0 car.

Ok - well, I am very wary of buying turbo's off eBay... so I might just suck it up and buy one new. So DSM 440cc Injectors... and what is a good FMU? Hard to tune, will it work ok with this setup?

Intercooler, Wastegate, and BOV will be from eBay. :)

What's wrong with boosting it at that mileage?

I went jooce on my Lxi at 183k miles.

I would say go H22, gives you more potential (sp?) in the long run.

Engine is dripping oil, head was rebuilt 60k ago, the engine just seems unstable and for $400 shipped for a new engine, the investment will prolly be worth it in the long run... the previous owner hasn't seemed to taken care of it. Basicially, if the car didn't drive, then it was time to fix it. :o

d16_kickass (:D) - yea, I also thought about the loath of aftermarket support for the h22a... everything is pretty much buy right off the streets which would be really nice.

[john]

boost > swap. Every day.

I think I decided to go H22 in my car so thats what I said atleast:p

and your right, I do need a new name [ponder];ScratchHe

[Mario]

Seeing you are kinda in the same boat... what are you gonna do?

True, as long as your compression and leak down numbers are in line and decent, it could probably handle the boost.

I'd say boost it. You can go the FMU route for probably $150ish+ or just spend around $1200 and be fully dyno tuned with hondata+boost option and injectors.

save up a good whad of cash. Buy an H22 complete swap with HA mounts. Save up another good sum of cash and throw a garret turbo on it, save up more and forge it out, mess with the fuel system and up the boost. Be a damn fast car;)

not sure if thats my final decision but its up there:o

Haha... yea, now that I look at it, h22a just too expensive for the power it'd give me... like others said, I could prolly pull a decent $2000 turbo setup and be right around 200whp @ 2500lbs.

[Prelude97]

Mario, I would boost it. 4g63, I wouldn't do an h22 swap if you were planning on boost also (stock internals that is). H22's have very weak ringlands and they have FRM sleeves, which requires you to resleeve the block for any type of forged piston, its not cheap.

http://www.hmotorsonline.com/shop/sc2000search.cgi?what=page&item=30015 How can you say no to that?

hmm, maybe I should re-think my plan. I still got a long ways to go still, im broke:(

[AgressivMX3]

I definately would go turbo instead of the swap, I'm working on putting together a turbo kit for my 86 crx si. So far I have an intercooler... ;ScratchHe ...that's it.

[LeonZ]

yeah, i would boost it also. less money, more power and fun

[Derrickcxhatch]

I ordered a B20 from hmo and it was $975 whare are you finding it 4 $400?

Sorry man - my engine is a b20a... JDM Preludes - yours is prolly a b20b/z from the CRV's. :) They are totally different.

[djet820]

Boost it. Then just build up the internals and then boost MORE! And how cool would it be to pick with ricers when they see your car and all of a sudden a BOV scares them away.

I know... especially with my car, cuz I am positive most people who see it (even on this board) think it's a piece of shit (and it sorta is now.. till new paint job and suspension setup). :D

[djet820]

When I get my turbo setup done....
We should run....
it'd be fun....

We will. :)

I say boost it. There aren't too many boosted 3rd gen preludes. I am also currently working on turboing my car. The best deals are to be had on ebay.

I don't know anyone else on the board who has a 3rd gen (except Weston)... so I think it'd be pretty unique as far as the HAI-clan of cars. :) Yea, eBay has good stuff.. I refuse to buy a turbo off eBay, but pretty much anything else I can get I will from eBay. :)
