Hey I have a question. I did a search and nothing came up on the topic. I was saving to get a B18C5 but my current engine has way too many issues. I'm getting a B16A with an lsd gearbox for a good price and I'll take it as I can afford that right now.

A friend fully built a B18C1 and it met a sad end on the dyno. A valve dropped.
The head's totally gone and one of the pistons melted. The cylinder wall also got a hairline crack by that piston. He can get it repaired but nobody locally can do this well.

This block has a new water pump, oil pump, cant remember what rods he used with the Weisco pistons.

I'm thinking about buying the B16A swap and using the B18C1 parts he has. The crank, rods and 2 pumps.
I know theoretically this should work and give me a stroke to 1.8, but did anyone do this before? Can anyone confirm that I can do this?

I plan to use the P30 pistons, and if the rods he has can't work with them I'll get another set.

Will the crank fit?
Will I need the B18C1 sump pan also?
Will the pumps fit in my block?

Any advice would be appreciated.

 

If your friend dropped a valve then I don't think you will be able to salvage any parts.

As for stroking a b16a, search under user crx=si. He has been the most successful with these types of set-ups I've seen on here.

The bottom line is you can use a stock crank and rods but you will need a custom piston with a raised wrist pin.

 

Well maybe it floated, I can't remember exactly what happened to the valve.
Bottom line is that the head's fugged up good. Only the Cams and gears were salvaged, and I don't trust them. His mechanic said only damage to the block was the piston and crack on cyl 4. I'm guessing the rest of the parts will be ok because he scrapped it out.

Why a custom piston with raised wrist pin if the rods are stock? Clearance?

 

Lol. Yes, clearance would definitetly be a problem with a stock piston.

You realize that a stock B18c/B16B is about a 1/2" taller.

 

Your B16A block is significantly shorter than a B18C block, hence leaving less room for the larger crank.

 

Well this kills the idea. I didn't know that. I thought since the b16b was a destroked b18c, and assumed that the b16a and b were the same height, that it could work easily.
Assumption fail.

So If I use pistons with higher wristpins can this work and give me 1.8l?
Or just forget the whole idea and sell b16a then buy b18c5 when I could afford it?

 

search tech43 lololol

sorry, had to.

 

B16B block is taller than B16A block. Why not rebuid the B16A and use B16B pistons and cams? Just have it tuned properly for it to make good results.

 

Lol, only if you want a smoke machine.

 

you can run the pistons with the wristpins moved up for the 95mm stroker motors, which are usually off-the-shelf along with some B17-length rods to run the GSR stroke in a B16A. The only thing you could use from your friend's motor would be the crankshaft. Not sure if it's really worth the trouble, but it would make more torque than a regular GSR motor.

 

Will a B17 rod work with a GSR crank? I thought the B17A, B18A/B, and B16A all had the same width on the big end of the rod.

 

the only selling point IMO of doing the GSR crank is that you can get minimal machine work done to get everything done. I'm pretty sure you are right, but a local machine shop can get you fixed up on the rods.

my buddies and I generally do LS crank in the B16, running B16-length rods along with custom pistons. The custom pistons are not off-the-shelf parts, though. But the GSR stroke B16A is also a viable option if you want it done without waiting and can get a local machine shop to help you out.

 

Thanks for the help guys. I looked up crx=si. He did work on B16's, but not this. He did some extreme work on it.

I wish those pistons were off the shelf. I'd get them and go with it.
I don't live in the US and getting them made would be difficult.
Guess I'll just go back to the original plan. Get the B16a and leave it alone until I can afford a B18C5 swap.
It does have some mods already. A pnp head I believe and c clutch. I'll have enough fun for the while with it.

 

I know crx=si personally and yes, he has built a GSR stroke B16A with the setup I described. Not sure if he ever posted it online though. If you don't want to fiddle around with customizing or tracking down parts for such a build, you may want to consider getting a B20B/Z block to build a 2 liter motor with all off-the-shelf parts.

 

What about the weak walls of the B20?
I sorta wanted to have the B16A stamp on my block, but 1.8 displacement y'know. It was for um.... competition class purposes

I still haven't gotten the B16, getting it next week.
I know someone in NY who may get those pistons for me, so it's still undecided.

 

Just buy the eagle stroker kit that's 1 I got for my b16 n I love it it put it at a 1.8

 

It is all a misconception! B20 last just as long as any other motor! If done right will last just as long as a b16/b17/b18! If you honestly want a motor to last don't mod keep it stock and stop worrying...
