hello everyone, im new here..

i have a 85 model prelude that i dont know much about. and im basically getting tired of its stock performance..

i have around $1000 to spend.. what sort of work is recomended to help bring up the power output?

its the twin carb model with ALB..

 

sell car, add $1000, buy a 3rd gen lude or something else... CRX???

 

well ive thought about that.. but if i wanted a new car i sure as hell wouldnt get the same newer car.

so wat mods can be done?

 

nothing that will give you any REAL significant increase, sell it please! for what-ever you can get and buy something else. no company even makes an intake for that car!

 

ive heard that 45mm side draft weber carburettors are good

 

The engine is an A series with an iron block. I've also heard good things about the side draft carbs. The later Accord Lxi (?) is basically the same as the '85 SI Ludes but with different con rods and pistons. I don't know how similar the Lxi's is to the carbed version but they are all A series. Talk to Jamie and Niphty87 on hpoa.com. They know allot more about the 2nd gen Ludes.

 

except he probably has a base 85 prelude with a 1.8l.
in any case, the aftermarket support is very limited for that car.
modifying that car would be nothing else but a waste of money.
for god sakes an 85 lude runs a whopping 18sec in the 1/4mile, and lots of mods/money later it will still be nowhere near 15s. its just not worth it.

 

"Don't chrush 'em, restore 'em."

Oh yea, DriverGT5 is also someone to talk to. B16 in a 2g

 

yeah i see, thats cool, but im not building a drag car, i just want it to have a bit more punch thats all.. and be more responive, just for normal every day use.

 

engine swap

I agree

Any accord engine up to '89 would be drop in and pretty inexpensive. Then theres the everything custom route with a b or h series. The advantage (or disadvantage, depending on how you look at it) would be to lose some weight by going with an aluminum block.

 

well.. how much would i be looking at to swap an engine??? and what sort of mods would i need to do to the car to acheive this?

 

Price I dunno. Thats not a highly sought after engine like the usdm version of the zc. You could probably find an engine and tranny for around $700. You'd need the engine, tranny, ecu and harnesses (preferably from same car as engine), axles, and hubs. Theres some other stuff that you'll need but thats the main componants. You might be able to use the brakes off a newer Accord along with other random upgrades.

Although I hate to say it, but you could also spray. Its an iron block so its definatly capable harnessing lots of power in stock form.

 

spray???? wat do umean?
apart from that, im not sure that i want to go as far as carrying out all that work. for a start its going to cost quite a bit for all those parts, then let alone modifications.

what do you think if i was to put a lumpy cam, extractors, head flow work, and 45mm webers?

 

nitrous.

Thats another route you can go. Although I don't know how much aftermarket support there is for the carbed a18. I do believe Webber makes individual carbs for it. Then port and polish. Who makes cams for your engine?

You might be able to swap some parts from another a series. For example, the only difference between a 2g Lude SIs engine and the Accord of the same year is the compression ratio. If the bore is the same for the SI and the carbed, that might be something else to consider. Theres also a chance that you could swap a head, ecu, and intake manifold to make your engine fuel injected. That would probably cost about the same as the mods you listed and give you more options in the future.

Don'ttake what I say as golden. I only know some of this from a roommate who had a '85 SI. If you talk to Jamie, Niphty87, or Drivergt5 on hpoa.org, they would be able to tell you much more about what you can do than I can.

 

aahh yeah, well prob with NOS is its illegal for street use in Australia.. and it SUX big time.
is it possible to swap a twin cam head onto the original block and keep the existing carbs.. and maybe swap the carbs for webers later???

 

That, I don't know. I'm pretty sure that all twin cam a series engines are fuel injected. If I were you, I'd look at Accords up to 1989. I don't know about Australia, but in the US they all came with an a series engine up to '89. Parts off another a series engine are almost garanteed to fit yours.

Go look up hondaswap.com and accordinglydone.com for more info on those engines. It would all be an experiment due to the a series not being an engine people usually swap or modify. However, all the same rules apply. And theres a real potential to make that engine very unique and definatly more powerfull.

 

cool. finally some posotive information!! yeah wat do u reckon if i just increase the compression a bit, port polish, stage 2 cam, extractors, and maybe webers?

 

Sounds like a good start Although, you'll probably have to mill the head to raise compression. I could't find any stock pistons that would fit that bore. The a18 has a bore of 80 where the SI has a bore of 81. Down the road, however, you could over bore your block and get the pistons from another engine. Just be sure to clay them first.

 

clay???? i was thinkin to just mill the head.. im not really interested in changin the internals yet
