swap to gsr - Honda Forum / Acura Forum

hey again guys. my 94 ls engine has racked up 175000 miles and i want to go turbo on the car. alot of problems have came up, and everything is leaking into the wrong places. i have decided to swap my engine into a b18c1 gsr engine, and then go turbo. what are your opinions on this? i have no clue if any internal of my current engine is on the verge of breaking, so i dont want to risk it with a turbo. so far hmo.com has the best responses for good engines, can someone second that. i would like to try to swap the engine myself, (noob question) is there some site or book that can tell me how to do the swap? i dont want to pay someone close to a g to do something i have potential to do. thanks for any help you guys can provide

http://helminc.com/ you can buy a helms manual from there. That will tell you how to pull your old motor. Then you just have to wire it up for vtec and switch out the ECU.

Why not just rebuild your engine and turbo it? Have you considered that? If you have, the B18C1 engine is a very strong engine to start a project from. I would buy a manual and do a lot of research on how to do this swap so it goes as smooth as possible.

Why not turbo LS? Everything is way cheaper to buy/replace and you'll have plenty of potential.

thanks for the reply's so far, as for keeping the ls and do a rebuild to it, i considered alot into choosing a gsr swap.
ls: ups and downs
already have the engine +
easy to boost on+
needs complete new internals-
175,000 miles on it already-
comparably low redline-
comparably low stock hp-

gsr:
still need to buy engine and install -
will need better tune - (not really)
can use stock internals+
> 35,000 miles +
better redline+
better response and power for time out of boost +

im trying to get around 280+ whp and stay street legal fyi

there are more things that also affect my decision, but i cant list them.
thanks for all help you guys provided. what should i do with the b18b?

LS:
+For the price of a stock GS-R swap, you could rebuild the internals with bulletproof stuff (and virtually have ZERO miles) and run boost levels a stock GS-R could only dream of

Who cares about stock hp levels when you're going to be highly modified and at 2-2.5x stock hp levels?

And how exactly does the GS-R have better response and power off-boost? Last I checked, the LS has longer stroke/powerband more suited to midrange/more low-end torque.

Your logic so far seems kind of strange to me. You're spending way more for a block that is no stronger... when you could spend the same building up the LS, have better reliability, effectively lower miles, and a much stronger block in the end. You're taking a stock 10.0:1 compression block with some miles on it over a freshly rebuilt strong as a mofo block that will have whatever C/R you want and will be easier to tune for about the same price.

that does seem logical. you have a good point with what you said. can you or anyone throw me a decent setup below 2.5g's that will keep me passing somg w/ a greddy turbo kit and would be good for 300 hp? thanks for the help on this, im goin back to the drawing board.
peace

edit: juss going to start a list of what might need to be replaced...cams, pistons, rings, arms, crank?, gaskets, valvetrain (need more specifics on what parts) anything else? is it possible to hone a block in my garage? cuz my auto teacher was honing a inline 6 in the shop with just an air rachet with some spring loaded device at the end of a flexishaft. i dont think that would bee too accurate, right?

If your shooting for 300whp, Your better off doing a custom build. All the bolt-on turbo kits are made for the street / daily driver type cars generally shooting for 200-250 range.

Piece one together, better parts, and economically smarter. My .02 cents.

For all the money you're talking about getting rid of your motor for a b18c1(which is a nice motor i must say so myself ;-) haha ) and then prepping it for boost and then boosting it. You coudl either rebuild your current motor than boost it. OR you cuold just go N/A for now and get a k20 swap and make 210-220 hp and have over 220 whp and have insane potential, but that is mucho dinero.
