Well im still in the dicision of the gsr vs lsvtec...I want to do the lsvtec but i cant have a motor go on me since this is my only car as of well for awhile..long while..I beleive im going to go with the gsr...my question is i know my car can run 14.8 consitently so im guessing an SiR(B16) rex runs around about 14.2?? Ive heard the ls vtecs run from 13.5-14.2 but it leaves me thinking well would a gsr run the same 1/4 as an ls vtec or would it be off by like .2 ? OH another ? i love the sound of Vtec from the B16 because its a single stage and wicked sound but i dont really hear that with gsr's why is that? it sounds just smoother and a queiter vtec???

 

ls,vtec with a b16 head is better from what i heard its a "mini type-r"

 

b16 head the best flowing head of the b series... Thats why the head from the b16 is used on ls vtec setups and not a GSR head

average time for a b16 crx is 14.7... 14.5 wit a good driver and on a cool day

 

Yea i figured it was a little better cause i guess the block is actually a tiny bit bigger with the ls...im not sure if this is dumb but has anyone ever put a b16 head on a gsr??? My whole problem is the OBD thing...i can get an sir head and be odb0 but then i come into visual problems with smog because vaccum lines...i can get a gsr but then its obd1 or 2..i would be guessing on a 94-95 gsr cause its obd1 so its probably just easier to convert.

I beg the differ.

So the factory port job on the ITR dosent increase its ability to flow better?

FYI: Somewhere i seen a chart, a GSR and B16 cylinder head where put on a flowbench and the B16 outflowed it by like 5% up top, down below they were dead even.

LsVtec will stay together all day long if you build them right, and you can build one right for cheaper then a gsr swap. Plus they make more power and more TQ.

the only diffrence between a C5 head and a B16 head is the P&P. Same head besides that.

 

Damn you guys are making my mind crazy!! Ok damnit its final....im doing lsvtec...i have an ls motor in my rex BUT im going to buy another one so i can work on putting it all together then sell my motor stuff i have as a swap for around 1000 so i can buy either a b16 or gsr tranny and my ecu...setup below
B18(A/B) Block
B16 Si-R DOHC Vtec head
B16 Pistons
ARP rod bolts
ARP head studs
ARP crank main bolts
Vtec oil pump (B16)
Vtec water pump(B16)
B16 Timing belt
B16/GsR tranny
Crank Pulley
Flywheel (ITR 14lbs or Chromoly 11-12lbs)
Clutch

Sounds about right? i put the pulley clutch and flywheel just cause its my list of stuff i need and want. Also now the axles are suppose to be ls axles even with b16 tranny but what about the intermediate shaft??? Ls or Vtec????

No.

C5 head, has different cams, and better valvetrain.

The only difference in the casting is a factory PORT not <U>polish.</U>


Your setup sounds good. Remember to replace all gaskets and bearings.

You will also need a lsvtec oil line kit.

Axles use 90-91 LS axles, along with intermediate shaft. You can use any b series intermediate shaft. Just make sure to get the proper seal for the 90-91LS (or whatever transmission is used) rule of thumb. Match the seal to the transmission.

Good luck!

 

B18C in a CRX would run easy 13's up here.

14.3@97 with basically stock B16A. My vote goes to LS/VTEC with B16A head

 

ls/vteck is the way to go for the tQ. gsr has a whole lot of rms and they go up fast but they die out at top. and in our shoe boxes tQ is what you need so the car can strech to the finish line. MY VOTE IS LS/VTECK.13.89 ON NITTO 555R, GSR HEAD LS STOCK BOTTOM END! OH YA FULL INTERIRER.

 

why not just build b18 vtec block with b16 head

also.... Which head do yall prefer for B20? GSR or B16?

 

I've asked that question to 3 engine builders (locally), and the consensus is the GSR head is the best.

 

ET depends on alot of other stuff besides power, like traction and a driver's ability to launch well. For this reason, it is hard to estimate ET. But trap speed should be 96-98MPH.

 

Just to give you an idea.
My B18C5 with 182 HP at the wheels does 105 MPH at the track.
Fast enough for high 12's but I run a consistent 13.4
