polly_x Posted March 18, 2007 Share Posted March 18, 2007 OK, quick one hopefully. Trying to finish the conversion to V8 today and getting round to the exhaust system. I have the manifolds and downpie/V section from a Range Rover Classic. Upon a quick mock fit I guess these are totally different from the defender V8 version as they look like they will foul where the removable cross member goes? A couple of bits to help me move forward: 1. Are the actual cast manifolds the same on a 3.5 Carb and a 3.9 RR Classic? 2. Is the V section the same? Meaning I can just get the correct downpipes? Anyway, as ever any help appreciated. Stu Quote Link to comment Share on other sites More sharing options...
Mark90 Posted March 18, 2007 Share Posted March 18, 2007 Carb and efi manifolds are different. Efi ones are better and have a more efficient flow, these have twin downpipes. Can you not use the gearbox crossmember from the donor, or do you not have it? As the engine, gearbox and crossmember mounts are the same spacing on a RRC/90/110 this should fit ok. I'm guessing the doner crossmember would be the type that has the ends bent upwards and allows the tubes to the Y-piece to pass under it. The drawback to this setup is teh pipes area bit more vulnerable to damage off road. On my conversion I used the standard 90 square crossmember and had a custom stainless system made by Longlife. I was very pleased with their work they din't have a lot of room to route the pipe, and the price they gave me for the Y-piece alone wasn't much more than an off the shelf one from the likes of Janspeed, I already had Janspeed headers.

western Posted March 18, 2007 Share Posted March 18, 2007 the 3.5 engine came out of V8 Freals 110 which now has a 3.9efi fitted & still on the road, so there's no donor vehicle to rob parts from. Quote Link to comment Share on other sites More sharing options...

Well not technically speaking............I know where V8 Freak lives and maybe I could pop round later under the cover of darkness........

Nice Pipes! OK, next question. Is the standard crossmember on the 2.25 different to one from a V8? Just to make things clear. I have, 1. V8 3.5 Carb in a 90 2. 3.9 EFI cast manifolds with the twin downpipes from a RR 3. Standard 90 2.25 crossmember From what you say above, that lot should go together no problems? The 2 down pipe outlets seem to be sitting exactly where the crossmember should go? Driving me bonkers now! Quote Link to comment Share on other sites More sharing options...
Mark90 Posted March 18, 2007 Share Posted March 18, 2007 Nice Pipes! Thanks, I wish I could do thet kind of work myself. OK, next question. Is the standard crossmember on the 2.25 different to one from a V8? No idea what a 2.25 crossmember is like, square one above is as standard on a V8 90, but some RR V8's have different crossmembers. Certainly those with 3.9 EFI do as mentioned above. to make things clear. I have,1. V8 3.5 Carb in a 90 2. 3.9 EFI cast manifolds with the twin downpipes from a RR 3. Standard 90 2.25 crossmember From what you say above, that lot should go together no problems? Maybe, but finding or making a Y-piece that fits will be the tricky bit. The 2 down pipe outlets seem to be sitting exactly where the crossmember should go? Aye, like I said above RRC with 3.9 EFI does not have a straight box section crossmember, the ends bend up allowing the exhaust to pass under the crossmember. This is why I mentioned the donor vehicle, I thought you where fitting 3.9 along with 3.9 EFI exhaust and if you had the original vehicle you may have the required crossmember. Driving me bonkers now! Been there and got the t-shirt, I tried a few Y-pieces to see if anything came close that could be modified, but with me having Janspeed headers to I gave up and spent the money on custom built.

polly_x Posted March 18, 2007 Author Share Posted March 18, 2007 don't fancy your chances of getting away with that OK, still looking around at options. Anybody used this system from Rimmer Brothers? Seems a good price for the complete setup? Cheaper than Janspeeds at £469 all in? http://www.rimmerbros.co.uk/cgi-bin/rimmer...fender/exhausts Any views?

V8 Freak Posted March 18, 2007 Share Posted March 18, 2007 Stu.. Looked through my collection of "Why the "F" did you take that shot" pictures.... Shot from rear forward when gearbox had been refurbed, original 3.5 engine and transfer box way back then.... Cross member is tubular....

Mark90 Posted March 18, 2007 Share Posted March 18, 2007 Either that tubular crossmember or the square one in my pic will be fine for a stardard carb manifold/downpipes/Y-piece. However you will have problems using a 3.9 EFI manifold/downpipes/Y-piece unless you use a crossmember from a 3.9 EFI RR. Quote Link to comment Share on other sites More sharing options...

Need to find myself one of those 3.9 EFI RR cross members or just buy a whole new system designed for the car! Anyone know any LAnd Rover breakers in the Herts area? Stu P.S......Cheers for all the help guys! Quote Link to comment Share on other sites More sharing options...
polly_x Posted March 19, 2007 Author Share Posted March 19, 2007 Well, after considering loads of options and spending too much time laying under the Landy in the cold at the weekend pondering exhaust options I decided to just bite the bullet and buy a complete system. This should be arriving in the next day or 2. Its the Rimmer Bros system and seemed like a good deal for 469 all in delivered with all fixtures and fittings included. Will let you know how I get on when it arrives. Quote Link to comment Share on other sites More sharing options...

Ozyboy Posted March 19, 2007 Share Posted March 19, 2007 Mmmm, i had a rimmer sport system on a v8 90.... Bit of a tail. Sounded lovely when i eventually got it to fit. Advice mode. Watch out for the starter wiring, as it gets pretty hot, and in my experience needed to be re-routed to avoid melting. That was after 5 different manifolds sent as they wouldn't clear the starter... From memory they are made in Devon, as i ended up dealing with the manufacturer over the whole fiasco. Hope you have better look than i did. Recently used Zorstec see www.zorstec.com in Bradford. Very good service. Loads of work on Harleys etc. Will make what you want... Full system for a TDI 90 well up out of the way, to my spec 2.5 inch etc. £50 more than a rimmer, and this is stainless, not the rusty version... Hope this helps.

V8 Freak Posted March 19, 2007 Share Posted March 19, 2007 You see Ralph... I kow where Stu lives and I could go hunting for a nice shiny exhaust... Would have to add in about 10 inches somewhere though !! Quote Link to comment Share on other sites More sharing options...
western Posted March 19, 2007 Share Posted March 19, 2007 you could do a swap his new exhaust for your x-member Quote Link to comment Share on other sites More sharing options...
polly_x Posted March 19, 2007 Author Share Posted March 19, 2007 Well cheers for the advice. I guess I will find out how good it is or is not at the weekend!!! Neil, keep your grubby little hand off my shiny new exhaust. If you do feel the need to lay under my landy, I will give you a wire brush and some paint so you can tidy up the chassis!!!!

Nope, ive been assured this will fit with the current one. I dont think its any deeper than yours. Just square. Quote Link to comment Share on other sites More sharing options...
