What do you guys recommend for main bearing clearances as well as rod bearing clearances for high HP turbo motors? I'm kinda thinking about running the mains a little looser than teh .0016" max recommended by the shop manual to maybe .0025. The rods I was thinking about .0025 too. What do you...

Hey guys, I'm putting in an ls motor in the crx for a little while until i get the gsr motor built. Just wondering if that throtle body will fit the ls intake mani. Reason for this is I didn't get some of the brackets with the motor that the cable attatches to, i was hoping maybe a throttle body...

well I went to the dyno today to tune my haltech ems. fuel was fine and as was timing, but every run made just around 140whp. The motor I have is a jdm b18c1 and I'm really confused. The low speed lobe made perfectly flat torque at 112ft-lbs and when vtec hit it spiked to 125ftlbs and just kept...

Well I finally finished my crx this winter. I put in a roll cage, stripped the interior, made a sheetmetal dash, put in a gsr motor, put in a haltech e6x, got it painted etc... its been a 3 year project working on in weekends when I'm in town from college. I went to the bmv a little while ago...

I really want to know how to select turbine wheels and turbine housings for turbo's. I know a good rule of thumb is to select the housing/turbine that will flow roughly half the volume that the compressor will flow... But I'm kinda confused on some things... like a original gt30r ( the...

I've been reading about people milling the main cap's and saddle's for more crush on the bearings... I've also read about people honing the big ends of the rods. Is there any real benefit to doing this? Is there an engine builder here that does this?

can anyone tell me if a 99-00 civic si vss will work in an s1 cable tranny??!?

I have a jap gsr motor and I'm thinking about going turbo. The thing is the compression ratio is 10.6 and that scares me. If I rip the block to change pistons I know I won't just stop there. I'll want rods, sleeves, cams and everything else I can think of to make this a decade long project, and...

Well this sucks for me. I've been working on swapping a b18c1 into my crx this summer and I go back in 2.5 weeks. I ripped out all the wiring and crap and I installed a haltech. I think I wired it right because I get the injectors to fire, motor to crack, etc... But as for spark, I dunno, I'm in...

hey everyone, I have a 90 crx with a b18 swap and an s1 tranny. I bought the clutch cable for an 90-93 integra and it doesn't fit right. The adjuster is maxed out and I even had to pull the lever arm on the tranny with a prybar to slip on the cable end... I don't think this is how its...

I'm almost done with my b18c swap into my crx and I was wondering if the stock 22" core radiator is ok with this motor. I don't have much money but I was maybe wondering if some other honda radiator would work better. Let me know what cools you guys down.

If anyone has a base map for a jap b18c1 can you please let me know what the timing is through the rev ranges? I need to tune my haltech and I just want to have an idea of where to start. Also, if anyone knows the rpm vtec engages and the rpm the IAB opens, I'd really like to know that too. Thanks!!

I'm tying the rest of a haltech e6x system to my 95' gsr motor and I'm kinda stumped on what the heck the idle air valve does. If someone could tell me how it works, or better yet, someone who has a haltech tell me what wires go where I'd greatly appreciate it :blink: . I think I have a good...

does anyone know if the 94-95 integra gsr's have saturated or peak and hold style injectors. And while I'm at it, does anyone know what cc's they flow? :blink:

I bought an e6x haltech system recently. I've sorted out all the wiring and all. Just curious to know if anyone here has put one on thier car. BTW: I did this to a gsr swap on a crx hf

there's a little hole in the crank between two of the threads for the flywheel bolts. I'm hoping that that hole is just a reference for TDC or something. Is it ok if I just install the flywheel in any position or do I need to install it a certain way. I hope to god these things are internally...

is just the bare casting of all b16 heads and the ITR head the exact same? I know that the cams(obviously) are different, and the ITR head has a mild port job, but can I make myself an ITR head out of a sir-1 head? I'd really also be interested knowing the differences (if there are any) between...

I'm swapping in a b18c in my 90 crx, and I'm looking for a descent radiator to fit. I was looking at civic and integra radiators and I would like to know if they fit ok without much modifacation. Particularly, if I can use 90-93 integra hoses with a civic radiator? I can make myself a new...

I'm buiding up a honda challenge car that currently has a gsr motor in it. I'm only allowed factory parts for the whole car except for heads/cams, which are completely free. so my question is this, I know that there are differences between the b16 head and gsr head, but which would be a better...

anyone know the torque specs for the flywheel, pressure plate and tranny bolts for a b18c1?
