My LS/VTEC build up

Just thought I'd tell you guys about my LS/vtec conversion project.
I've been collecting up the bits and pieces for the last few months now, and soon I'll be ready to do the deed!

I'm doing this to my 89 DA9 LS tegra, as I'm into mods and engineering etc. (want more go LOL).

The engine itself is in good nick, so it'll get new rings, bearings, balance, water pump etc.
Just did the research on the net and this site, pros and cons, and worked out what parts are needed.
Parts I have got so far are:

GSR head
GSR intake manifold, I removed the dual runner butterflies.
New OBD1 dizzy, my car is OBD0
OBD 0-1 conversion harness
GSR ecu with Hondata s100 chip
LS head gasket
braided line and fittings for the vtec oil feed (from pirtek :thumbsup:)
ARP head stud kit B16A
ARP 8mm rod bolts and nuts
build and tune

Getting a vtec solenoid off ebay as they are rare as hens teeth lol.
Also want to get some second hand pr30 pistons to bump up the comp ratio to roughly 11.5:1 instead of 9.8:1 if I use stock pistons.

I can forsee a clutch upgrade coming too!

Not worried about the cost too much, and yes a B18C would be straight forward.

good stuff

got any pics of the IAB plate or the inside of the runners at all?

if she throws a CYP fault code, try reversing the orange & white wire on the end of the dizzy plug

Might wanna change your gearbox. Swap in a Short ratio B16 box.
LS gearing is too long. Otherwise looking good.
Never knew you could remove the dual stage thingo in that intake mani.

Yep, just for you lol. But I already reassembled the manifold.

Cool I'll keep that in mind, I do have the colour codes for the connection to the obd0 loom so we'll see if it's good or not.

I thought about the manifold and didn't want the extra stuff so I pulled it apart, cleaned it then reassembled using 26mm shorter bolts, as the butterfly assy is around 26mm thick. It all lines up too.

Also pic of ecu and harness.

Gearboxes, especially VTEC B series are pretty hard to grab lol. I'll try though, as the LS one is shagged anyway. Input shaft bearing, synchros etc all shagged, still works though with 130-140w oil!

hehe, good luck bro.

I want to see better times come out when the swap is done :)

Second that :thumbsup:

ahhh,so thats what those little bastards hiding in my manifold look like........
thx for the pics
twas me,id prob just ditch the manifold alltogether,but will be interesting experiment none the less.

be careful of the obd0>1 CYP & CKP sensor colour swap,dont know if its the same on the B18A but on the D16A8 it happens & the last conversion harness i dealt with actually accounted for the swap anyway,so maybe check it before u go swapping wires at the dizzy end.
still... the CYP wires on your new dizzy look arse about anyway,but who knows how they wired it internally...

Trying not to go too overboard on a budget car so thats why I'm using what I managed to find. We'll see how she goes on the tune and strip though!

I'll let you know if the wires needed to be swapped or not!

You also need to get roof racks for the car :p

Lol, might just leave them off for this one lol!!!! You need em on your beast, helps with aerodynamics on 80's model civics!!!...proven already!

nice u gonna hav alot of fun, mate got LSVtec on da :D

cool build.

Thanks, we'll see :D

Picked up another piece of the puzzle tonight.

These will bump up compression from 9.2 to around 11.5 to 1, definitely NA now!

Hey I have LS/Vtech race integra, For sure a good package. I have the TypeR Hydro box with 4:751 final. The B16a box has a very good ratio for track but very weak syncros.
Let me know more when you can Happy to speak to you more about your build. You can see more of my build on the temple of vtech asia.... the black beast ...

Cool! I'll have a looky. Would love to take mine to a track day!! but it would need suspension...bad!

Definitely looking into that option. I've been told the internals are very similar and a different final drive, eg Type R etc can be bolted in...

Do you have one available :D

Sorry sold my old B18a box and my old B16a.
I have the TypeR hydro box in the car now...
I do have a nice LSD to suit a B16A box... it's a clutch pack type I also have a TypeR LSD to suit B18 box

At least someone on this forums knows what there doing

Keep up the good work!

thanks guys. It's pretty fun at the moment reving it out!!

Reving out to 8k + will be more fun!

Still need to get a few more things before I pull it apart.
BTW this is the car thats having the operation!!sleeper lol.

Kewl build im keen to see wat kinda improvment u get when its al done

how can it be either? :wave:

it is most certainly 4.4.

4.7 if he finds a type R FD..thanks for stating the obvious :)

Only the later model DC2R's came out with the 4.7 ratio?

DC2R boxes are like gold lol!

I just might pull apart my box and get a hold of a R diff and see what fits...

Car doesn't start now, starter motor shagged so I gotta pull it out and inspect. Must be telling me something lol!

Also head stud kit part number is 208-4601. I guess I'll find out if it works....

Its a sign from the Honda Gods...

Do it already :)

Doh!!

Looks like I might have to buy some 4306's after doing some more reading on other forums...

Here's one of the things I read too.
http://www.modified.com/tech/0411scc...ine/index.html

Pulled out starter this morning inspected and fixed it. It had been replaced before I had it. The solenoid contacts were worn so no power to electric motor. Piece of copper and some soldering fixed it good as new!

im seeing if im inspired to do this conversion on my DA9 aswell or just drop a whole B16A in it. Just kinda iffy on the drilling the hole part.

My lil bro owns the car now, and he has driven it (thrashed it) for 9months, but it's back down in my shed to get a VTEC conversion woot!

Pulled the engine/gearbox out today and used a Karcher to blast all of the oil all over the engine and engine bay from all the oil leaks! All the engine mounts are shot so they will needreplacing too.

Went to Toda yesterday to sort out the ECU with a base map, so I'm glad that's sorted, thanks Adrian!

More parts have been ordered in such as, timing belt type R, water pump Type R, oil pump, head studs, spark plugs, gasket kit, bearings.

Getting headers, adjustable cam gears, and hopefully Type R throttle body too. Engine will be on a stand once I get some long bolts to mount the bloody thing! then I can start pulling it apart and checking the innards! Last engine I built was an R32GTR with an RB26DETT with forged innards etc, ran 480RWHP for 2 years then sold it, and a 1litre 3cyl turbo charade engine with a T25 lol, so I have the gear and experience to build this baby up!

Okay, engine stripped down to bare block and inspected. Deglazed bores, and there were still hone marks evident, gotta love honda engines!

Rods and P30 pistons taken to engine reco place to get fitted and ARP rod bolts fitted and big ends resized/checked.

Everything else has come in, just waiting for the heavy duty clutch kit. Then collect it all and pay for it!

So parts ordered were:

clutch kit
water pump 22T
B18C timing belt
tensioner
spark plugs
leads
VRS gasket kits for head and block= $$$
ACL bearings

Just running the GSR cams and throttle body, pretty much out of money now, but some performance cams would be nice!
Will look funny when it revs into the DA9 tacho red zone as tacho only shows to 8000RPM and redline starts at 6500RPM!

looking good, will make good power

Hope so! Thanks.

Got all the gear today as well as a bolt stretch gauge for the rod bolts. ARP recommends .0053-.0057 thou stretch, so I went with .0055. Measured up all bearing oil clearances, ring end gaps etc, and all is good and within factory specs. No rags used in assembly, just paper towel!

Bottom end is all done and sump is fitted, now it's all the external stuff on the block as well as the head to sort out and fit up.

Drilled head to suit dowels, modded B18A head gasket and fitted head studs, head and nuts to 80FT/LBs. fitted up adjustable cam gears, seals, timing belt, water pump etc.

Then fitted up breather box, intake manifold and oil feed line for VTEC oil feed. Got up to fitting the fuel rail and found out that you cannot re-use the B18A fuel rail and fuel reg. Rail bolts up and that as far as you can go, short of modding it to an end mounted fuel reg, and blocking off the original mount. I put up a wanted to buy instead!!! Pretty sure the VTI R and GSR intake manifolds are the same.

Managed to buy a golden eagle pro series fuel rail and stock regulator (thanks Benson), and fitted it up along with a short length of 8mm EFI fuel hose so it still has a banjo fitting to the fuel filter.
De-pinned both OBD0 and the new OBD1 dizzy to use the OBD0 connectors and fitted leads.

Today was spent looking for a radiator hose adapter that bolts to the head, as the PR4 and PR3 one's don't fit. Also today, the front cross member was removed, modded and headers fitted while it was off, then put back on. Nearly complete! Just have to:
Get hose adapter fitting
lengthen wiring to air temp sensor
reconnect rack to steering wheel
feed VTEC wiring through firewall and wire up
fit radiator
fill up fluids
sort out exhaust and o2 sensor
run it in and tune

Wiring done, and 02 sensor, may need one or two other things hooked up or fixed as engine light comes on after starting it.

Cranked it over with no spark and fuel till oil pressure came up, then fired it up straight out the headers, far out it's loud! So engine runs, just need that damn radiator hose adapter part.

Mig welded the exhaust up and bought a flange to suit the outlet of the header and welded that up too. So close!

geez you move quick. good work on the build.

Thanks, looks like you have been very busy in the past too :).
I've been rushing around getting bits, working then working on this when I can. I have to get it finished asap as my bro has to drive it back to Bundy lol.
Hopefully all goes according to plan!

good job,
i wish i had the time to do my car,
but working 6 days a weeks leaves me with no time at all, hence why its in the garage, lol

Thanks guys, yeah it was a relief to get it going :)

Yeah, toda put a base map on the s100, but it will be taken in for a check/tune on the dyno, once I get the last damn part I'm waiting on. Running out of time, that's for sure.

Managed to modify a standard B18A head coolant fitting and bolt it up. Lil bro took the car by tow truck to Toda to get fixed up and tuned. All good with 107.1 FWKW, Rev limit at 8000.
Glad I got it sorted, and in the future it will get cams and springs!.

Thanks to Adrian at Toda for helping out at very short notice, and you other guys (you know who you are!!!)

Excellent work bro.

If you're in Brisbane for long when coming to Bundy hit me up mate, live up here now :wave:
