what chassis is it going in to?

 

sorry its a 94 lsi coupe

Edit:

had a better look and the harness is different

 

well the z8 engine is OBD-2 and the chassis and current loom is OBD-1. its going to invole alot of splicing on the engine bay end i would of thought.

you can convert the ECU end with a simple harness, and maybe use the b7 IM on the z8 block for the senors.

why have you swapped the d15b7 for the d15z8? why not swap a d16z6 into it?

 

just wanted a replacement d15b7, the muppets sent the d15z8. just wonderd if it could b done b4 i play F*** with them. paid on tuesday and took them till friday to send it, they only sent it then because i was p'd off.

 

well if you can send it back and get either the d15b7 or a d16z6 as it will be far easier.

 

i just wanted a straight swap to get the bugger back on the road does the d16 fit with the b7 gearbox?

 

yep staright bolt on, all d-series boxes are interchangable apart from the DOHC d's.

the d16z6 box has the cloest ratio tho.

you will need a P28 ECU though to run the engine.

and the d16 has an extra 25bhp over the d15

 

i wouldnt even bother telling them lol.

 

your jacking the gezzers thread lol, make a new thread about. sure a few people will be able to advise you. but i know you wont be bale to bore the OE sleeves out that much, you will have to stroke it aswell.

anyway make a new thread lol.

 

well the guy felt like a plonker methins. afetr he pulled another motor which wasnt right. tho he spotted it this time b4 it got sent out.

As ive already paid in full they offerd me a b16vtec and all the relevant parts to convert at no extra cost so long as i let them have the bits that come out of mine and the dead d15b7. result.

so guys correct me if im wrong and just to make sure this goes as smoothly as poss il be needing:-

gearbox
ecu
loom
driveshafts
hubs and disks
calipers
exhaust header
engine mounts

obviously the motor too!

Anything else?
Oh i understand il need to add 3 extra leads to the ecu for the vtec?

 

they are offering you a b16?! Take it dude lol

 

yup his arm is snatched

will i need an obd1 to obd 2 conversion harness?

 

What b16 is it BTW? What did it come out of?

 

you want to run an OBD-1 ECU, so you need to rip out the existing loom in your car an replace it with the OBD-2 loom then buy a conversion harness so you can plug the OBD-1 ECU into it.

 

not sure which b16 yet will find out monday morning.

eh??? you lost me if i did that id end up back where i started. its alredy obd1 (d15). maybe what i should have asked is, are the b16 motors obd1 or 2?

 

if its a b16a2 which it most likely is its OBD-2, you can fit the loom and ECU and it will run, but if you ever want it chipped and mapped you need run OBD-1 ECU which has been pre-chipped with a B16A2 base map

 

got ya, cheers.

so thers no chipping of the obd2 ecu?

Thinkin for now il just get it running on whatever i can...........for now

 

nope, not at this moment in time.

yea once the b16 is in and running on the OBD-2 system it wont be hard to swap it over.

 

whers everyone stand on the hondata ecu's? wasthinkin about one of those as the next mod.

 

if you have a spare £600-£800 that you can throw at it then go ahead.

i would go with crome though mate, where are you from?

dont bother mapping a stock motor, wait till you have all your bolt ons then get it mapped.

 

seems pricey, there on hodatas website at $595 was planning on fitting it myself if i got one. was thinkin of the v3 since i can tweak it as i add bits.

so if i went for a chipped ecu id have to take it to somone with a rolling road, not really a problem thers one about 5 miles away. im in rhyl in north wales. in that case then i see your point with waiting until ive done everything im going to do to the motor.

decisions to make here.

cheers for the help again lads

 

you cant just go to any rolling road, it needs to be somewhere that can actuali use the software and chip the ECU, most dyno's just do power runs and club days.

craig is down south wales, dont know how long it wud take you to get there?

 

aaargh. pain in the arse. no gearbox for the b16. i am getting mmore and more p'd off with this place. if u wanna know who pm me. so they say they have a b18 in with everything i need. should find out in the morning if its a go'er. if not its refund time. plus ive found another b18 a little closer to home thats still in the car.

will i need to fabricate mounts for the b18 or is it a drop in swap?
