I have an ed xr8 engine which I want to convert to carb. what exactly is involved? do I need to change the timing cover? what dizzy and coil can I use? its got gt40ps, and I think that should be an issue. the engine is midly worked. strong bottom end, and a baby cam. I plan on using the edelbrock air gap manifold and maybe a holley sec vac or dp. can the btr be used without the ecu? or I might go AOD as I still want to have 4 speed. is there any other trans I could use? cheers

a small fortune $400, for carby, $300 for inlet manifold, $100, for gasket kit. New dizzy and coil and an auto elec for the tps. A grand? yeah right.

decided to stay EFI for the time being, Im getting it dyno tuned with full diagnostics. See whats going on. Ive gone this far now, it will cost me a small fortune for the conversion

ported gt40p heads, ported au lower/upper manifold (with 1 inch plenum spacer). 70mm EGR and TB, AU XR8 S3 MAF. BA 6 cyl injectors and J3 chipped. going in for a dyno tune on the 20th Jan, for diagnostics as it doesn't run properly. Idle hunt and too rich.

Hi. Just a quick question. Whats a good dizzy and coil upgrade for an ed xr8? Nothing too expensive. If you have part numbers, that'll be great. Its pushing almost 200rwkw. Cheers.

turned out to be the TFI module.

Hmmm. Sounds interesting. Im in the RAA (SA's version of road side assistance, so i might push it out on the street and give them a call. When i described the cut out at high revs. It was when im cruising along at, say 90, and i nail it. Itll drop to second, and will cut out at approx 4500rpm and start surging. Ive got fuel, as im running 29lb injectors and a walbro 255lph pump. Fuel filter is new

No and still original one.

Yes its the original unit. A couple of days ago it started and stalled after running for about 15 secs. Tried to fire it up again and nothing

Are you saying 200kw at flywheel or at the wheels? It already has a msd cap, rotor and j3. Im losing spark when its underload from standing start. Fails around 4500rpm.

i have gt40ps on my ed xr engine. they've been opened up quite a bit. bigger valves and lots of porting. I also run an au lower/upper manifold which has been port matched to the heads. 1 inch spacer for the plenum. edelbrock 70mm egr and tb. au xr s3 maf. BA 6 cyl injectors (which are 29LB). Pushing almost 200rwkw. Opened up the engine quite nicely. Oh, its J3 chipped too.

I do, its over on xfalcon. Ill locate it and put up a link. also, how does one upload a pic to your profile? im trying, but its not working

Hi James, here is mine. Its just a standard Davies Craig item

I have an efi 302 in my zk. engine had to brought forward 40mm as the aircon comp was hitting the strut tower. btr will fit with a small amount of mods to the crossmember. I have an engine and trans from an ED XR8, tailshaft is NC, diff is EF XR6, with ED brakes, lmao.

what ECU are you using?

Cant legally put a carbed v8 into a xf/zl. However you can go an efi engine. Cant go backwards - so to speak. Ring DTEI for more info. Been there done that with my ZK

They dont!! Hahaha

This is what is in it now. this manifold had a crack in it and i replaced it with the same one, but not polished

I did think about carb, but i wanted something different, more reliable and better drivability. When you start modifying you sacrifice something. I would strongly advise doing your homework before even contemplating an efi conversion. Ive had quite a bit of small issues that have been hard to diagnose. If i could go back and start again. I would go carb. The amount of money ive invested, i could of had a 450hp stroker. Instead i have a 180rwkw engine. Mind you the bottom end is stock. Mines a 1984, but v8 was still an option before the release of the ZL/XF. If you want to do an efi conversion in a ZL/XF. You can. Just cant go from efi to carb. Im running a btr 4 speed from the same car (ED XR8) My console is still standard. Hasnt been modified. The engine and trans ECU are mounted in the passenger footwell. I used a NC Fairlane loom with ECU and J3 chip.

Yep!! Only because the zk was released with an 8

The only things that are good is the gt40p heads and the explorer manifold. With the right combo, they can perform really well.

I asked regency what i had to do and i just went to rego office and filled out a 'change of engine' form. The list they gave me was all common sense really. Upgrade brakes and suspension, cat converters.

Hi dave ZK was released with a v8, so easy done. Had to inform them of the engine change and number. they gave me a list of what I had to do and I did it, however, they wanted access to the ECU, and its not stock, the engine you see here is the old one, NC V8, I now have an ED XR8 engine, GT40P heads, with Edelbrock gear
