I want to put a B16a into a 1991 Si hatch. My first 88-91 swap.

Im buying this swap on hmotorsonline.....

http://hmotorsonline.com/shop/sc2000...age&item=30002

So here's my questions...

1) Do I have to get their mount kit for $300 which is hasport? Or can I get various mounts from junkyards?
2) I do need to get their linkage for $110 right? I don't wanna mess around creating my own.
3) Would it be easiest to buy their wiring subharness for $60? Could I wire it just as easy without their subharness?
4) I'm assuming all cable trannys will work with no problem? I want the integra XSi YS1 tranny instead of the civic SiR Y1/S1/J1.

Thanks.

 

1) Yes, you will need B-Series motor mounts for 88-91 Civic. Hasports are nice mounts. You can go cheaper on e-bay.2) Buy the linkage, save yourself the hassle.3) I made my own subharness. Secondary Oxygen sensor, VTEC Oil Pressure, VTEC solenoid, and Knock Sensor. http://www.hasport.com/tech/wiring/EFSi-VTEC.PDF4) Gear Ratio's should be about the same.

 

 

Okay thanks,

Now anyone done this exact swap? Have you run into any problems?

 

Be sure to have money set aside for ANYTHING, that might come up, broken sensors such as TPS, knock sensor, O2 etc that might break in the process of the swap. Remove the crank pulley/alternator belt before putting the b16a in, ANY part you take off or think you do not need during the swap you should KEEP IT. Check for any type of leak (oil etc) before installing the motor, you would rather install gaskets/seals while the motor is on a stand, not underneath the car. Take your time and double check everything, good luck.

1 - Hasport mounts are great, they place the motor for axle position and therefore making your axle life longer, ALSO - Lifetime Warranty
4 - If you want the YS1 strictly for Limited Slip Differential the Y1 also can come with LSD (stamping on transmission), and it came out of the crx SiR

 

Okay thanks,

Now the stock B16a header won't align with an '91 Si stock exhaust right?

Also, how much of a "dent" do you have to make in the frame rail for the alternator pulley?

Also, I understand you use a 92 GSR upper radiator hose and a 90 integra lower radiator hose. Now thats with a stock '91 radiator, can you swap in a 92 civic radiator?

 

Help.

 

Bump.

 

i'm pretty sure the end of the header is different and won't mate up but mine is fine and has stok cat, but then again everything else in the car has been changed to da stuff like the complete harness. to make your 92 civic radiator work i think you have to make the brakets to hold it cause your car is set up for the full size one.

 

The exhaust will be about 3-4 inches off to the left and too short iirc.

The dent you'll need to make is just about 3/4 of an inch deep.

 

So can I put the '92 radiator in with the '91 radiator mounts and kinda create some makeshift thingy???

 

Okay like how big of an area? Like 4"x4"? And how long with a hammer is that going to take hitting that by hand?

 

"Now the fun part (no, it really IS fun!)

How often can you hit your car hard as hell with a sledgehammer, and not have to worry about it? Well now you can!

In order for the B16 alternator pulley to fit perfeclty in the engine bay, the drivers side frame rail needs to be bashed in about 3/8". Go to the HAsport web page for the EXACT location, but it's a square area, below the shock tower. Right on the frame rail. You can probably see where, but check HAsports page just to be safe."

"You need to make a large dent in the frame rail right below the shock tower (right under the rectangular hole). This dent clears the alternator pulley. NOTE: if you’re putting a JRSC in this dent will NEED to be further forward and a lot deeper. Trust me. Experience talking. We pulled the motor a few times messing with this. "

There was a link on Hasports website - clear instructions on how to do it with pictures, but its broken,

here we go:



" Get a hammer, and beat the crap out of the right side of the frame on the car, where your alternator is going to go. you need to make a dent roughly 2 inches in diameter and the dent needs to be at least a half inch. its in the same location as your right shock just alot lower. "

^^ This should help you out

 

Also, all the cable tranny's will work, you'll just need to make sure you get the right clutch. (big spline shaft vs. small)

 

Thanks it does help me out.

Last question for now, what short ram intake works well with the B16 without having to relocate the battery? A integra DA short ram intake?

Also short shifters (like skunk2) are the same for the 88-91 like you use the same short shifter for the 92-00? So do all skunk2 B-series short shifters work from 88-00?

 

i've had an eg radiator in a crx before but the person before me cut the bottom support out and it fit like crap my ef radiator in my b16 hatch fits fine though.

 

Do you still have your ef radiator fan wired and working?

 

ebay 88-91 civic/crx si intake...

 

ya it was in the and worked but was all rigged.

 

i don't have the rex any more though.

 

and do you want those ctr cams?

 

be very careful ordering clutches for the YS1, i've had like two customers come back with exedy stage 1's when they ordered it for the s1/y1/j1.

Also, the nice thing about the ys1 cable is that you can stuff hydro internals (persay an ITR 1-5 +diff+final drive) into a ys1 case, something that (from what I understand) is impossible with all other cable trans cases. So you can have the best gear ratios, FD options and still keep the feeling / setup of a cable. The YS1 has a 26mm input shaft instead of the 25mm like all other cables.

 

...So with YS1 tranny I can use 90-93 Integra axles, like str8 outta the box?

 

yes, and use the 90-93 halfshaft.

be sure to remove the dust rings from the end of the axles

 

no need to bang on the wall for the alternator it fits just right.
mine doesnt rub or knock.
