Ok, I know this is one of the more difficult swaps to do - although not as crazy as the h22a... Who here has done it? How do you like it? Any understeer problems?

My buddy and I are both contemplating this swap (he for his '88 crx si, and me for my '91 si hatch...)

Any advice for us? I'm shying away from the place racing kit, HA Sport is looking pretty good. hybrid-honda.org is very helpful, but I wanted to see how others here felt about their rides.

Anyone?

 

No one else replied so I'll throw some stuff at you...

Expect mid-to-low 14's dead stock. Like the Hybrid site says, the only problem is you utilize 3 motor mounts instead of 4, so it can be a little shaky in their opinion. From what I know the engine weighs pretty much the same as the B16A, so there shouldn't be any real understeer problems.

I'd advise the HASport kit... sgT says that one works best, and will fit the B18s into the bay with no clearance problems at all. For axles you need '90-'93 Integra, and you can just modify an Integra shift linkage to fit.

That's about all I know... HTH a bit. I'm also thinking about this same swap, and selling the B16A to my brother .

 

I was thinking about doing the same with my blown GSR motor, rebuilding it or what is left of it, then putting it in my Si. However, I am leaning towards just turbo'ing the Si and selling the GSR engine.

 

I have a b18c5 in my 91 hatch with the hasport mounts and theres hood clearance problems. I had to cut a rib out of the hood with a die grinder on the timing belt side. I also put some washers in between thehood and the mounting brackets+latch to raise it up a little more. You would only notice it if I told you though Understeer is not much of a problem for me.

 

i have a b18c in my 88 hf with a hcp kit no clearance problems

 

Be careful with the hpc kit, it makes the motor sit a little lower. Its only a problem if you have a 4-1 header like me and your car is lowered. Even with the hasports I have crushed my header 2 times.

 

Actually, i have noticed the same thing with my hpc kit... Like you said though, its only a problem if you have a header. The stock down pipe doesn't really sit any lower than the cross-members. Not really anything to be concerned about unless your really lowered.

 

hasport sits it engines a little more lower than hcp i have seen a hasport kit with a gsr i have the new kit but the old kit sucked and the header i use is the JDM 97 type r 4-2-1 w/2.5 collecter and a spoon top piece so it's much the same as the stock header but i don't have my car dumbed so it's not that low

Well actually when I first did mine I took it to a shop and they rewelded. They did an ok job and the weldes are strong,they've held real good. But i really recommend going with the place kit. I know it's a lil more in price, but hey I beleave you get what you pay for. Place has some good quality stuff. I just put in there front radiator support, so now I have awhole lot more room for my turbo and the double core radiator fits perfect. As for only runnin 3 motor mounts instead of 4 I would just have the rear mount welded solid. You eliminate alot of the vibration but it does stiffen it up alot more. But hey I need the extra supprt for all the tourque i'll be putting to the ground now. But I would definately throw in the GS-R motor and then turbo that instead of the sohc motor.

 

xtrafast, what hpc kit are you referring too? If the hpc kit is higher then there would be hood clearance problems like with the hasports.

 

the hcp kit pushes the motor towards the back more so the hood clears

 

Xtrafast I had the 1st gen hpc before my hasports so thats where I got my info, but I'm not sure about the new ones. Could you please measure between the IM and the firewall on your hpc's if you get a chance

 

the closest point is a little less then a inch

 

Tbone,

Have you ran your car down the 1320? Does the light weight chasis deffinetely help out? What is the weight of your car and mods if possible?

Im debating if i should swap out my setup which is pretty close to a b18c5, into a lighter shell..

 

Dragdc2, I only ran it when I had my 1st gen b16a 2 seasons ago. I ran a 15.2 with I/h/e with full interior and spare. My car was really heavy at the time 2440 with driver. Havent been to the track to race since, only to watch. The car is probably making 60 more horse to the wheels now. Somewhere around 190-200. Im not going to dyno it until I get my smsp header. Sorry if this didnt help much I know my freind ran a 12.1 with a fairly stock prelude motor in a 1800lb-1900lb crx.

Tbone,

Geezz a 12.1 in a gutted crx...with a h22 swap...damn.... weight i guess is the key factor..... i seen on a web page someone runnin 11.9 on a gsr block with a type R head in a fully gutted crx... so i guess with a car weighing only 1800 lbs with driver is the way to go for all motor....

Hey Tbone...what mounts did you use? Also was it hard to modify the shiftlinkage?? Any other major modifications...knocking back the firewall or using certain front hubs for the axles???

 

Dragdc2, Was the site you saw Ellis racing? I know fred from the track . I had 1st gen hpc on my b16 and hasports on my b18c5. I use jdm sir shift linkage, no mods needed. With the hasports I have plenty of firewall clearance, I even have a phenolic spacer between the head and the intake manifold and still have room . I have a si so no need to change my hubs. your axles will depend on what intermediate shaft you use. Check hasports web site, it explains it well. The crx I was talking about now has Roger Sangco from AEBS motor in it. you will see it in the mag's this season. I think his best time with the h22 was also around 11.9 but dont quote me

 

Hmmm cant remember if it was ellis racing..but i due remember he is running a b20vtec setup now..... heck im running a gsr block, everything type R up top, jdm 4-1 header, and a type R ecu. If you know the guy, how was he able to break into the 11s with a similar setup i am running? With my current setup in a gutted integra...dont know weight figures never weighed it....most say best i can do would be mid to low 13s. I will be running the car in street form this coming wednesday so I guess i will see what my car can do. But still how was he able to accomplish breaking 11s without internals???

 

Quick questions for you guys w/ B18C's in your CRX's...

Does a B18C engine harness plug into the existing CRX harness? Also, is there enought clearance to run a DC header w/ a Hasport mount kit? And lastly, I'm, assuming you have to change some plugs around on the ECU side to use the GS-R ECU, but how/ where do you change the wiring to get both the secondary butterflies _and_ VTEC to switch over?


Thanks,
ronb.

 

gsr and crx harnesses are not compatiable i had mine done by somebody else. yeah you have enough room to run a header the dc header is just as big as the stock header unless your talking about the 4-1 w/2.5 collecter and to dragdc2 he never said stock internals probably not i think it's pretty easy to hit high 11's wit a b18c in a crx high comp pistons cams headwork but the only prob is money i'm trying to see what i can hit with all honda internals exactly what is your setup

 

I guess it was ellis racing....i just went to the website and before i swore it stated his prior setup as a stock b18c block with a type R head running an 11.9

But i guess it was someone else who was running a stock b16a motor who goes by the screen name of poorboy on the clubsi.com board. he ran a 12.8 best in a stock motor..heck i would be happy with a 12.8 at this time...

My setup:

Chassis:
1995 Integra RS
Fully gutted interior
No ABS system, No Srs system, No Ac, No Power steering....
In the process of skinning doors and making a fiberglass hatch and front end...

Weight figures i dont have a clue...

Motor:
b18c block
b18c tranny
type r head (cams, intake mani, and throttle body)
type R ecu
Jdm 4-1 header....
cam gears dialed in at +2, +2

and i think thats about it......

 

i can get you a carbon fiber hatch for a pretty good price and why are you running a type r ecu get something better or just get a vtec controller and a FPR and tune it

 

I actually just made a fiberglass hatch myself... just need to finish it up and slap it on...

As far as the ecu..well i purchased it as i guess u can call it a package deal with my head...wheeled and dealed to get it for a real good price. Yeah my next step is to get a FPR and AFC. But first my clutch is slipping so i am going to be changing that when i pull my motor back out to check on some other things too......

 

o yeah im gonna run the car for its first time on wednesday...So ill see what it is capable of in its current status.....

 

Drag, Fred had a few tricks up his sleeve (nothing like cheating) but mostly his ddriving skills. He is probably one of the best drivers I have ever seen . He did run the 11.9 at the end of last season. He will be running in a integra this season, b20 powered. Theres a guy I know here in ct who ran a 12.8 in a gutted 95 rs with almost the same set up as yours . I think the thing that will hurt you is your low compression. He had 13.0 je pistons but the rest of his set up was like yours. Did you convert to obd2 to use the r ecu?
