Not 1000bhp per ton - but its got a Nissan engine :p

We've been working on an SR powered Westfield recently and thought people might be interested in the work we've done so far.

This is how it was delivered to us:

Some of the structural parts of the chassis had been hacked out so we had re engineer these parts:

The inside of the car wasn't much better:

Some of the suspension arms were bents:

We had to strip the whole car down, clean everything, sand back the chassis to metal and respray.

We then made new engine mounts:

The original engine was scrap, so we built another one:

Fitted it:

Got the intercooler and rad mounted:

Made up the pipe work. Just hope the radiator is big enough to keep it all cool, especially with the IC in front. You can just about make out that we've fitted an Accusump to help prevent oil starvation. We suffered oil feed problem with my S13 on fast corners - this car should be similar power to weight so we wanted to minimise the chance of it happening here.

We're about to finish off the brake pipe work as this was also unusable. My next job will be to make up the dash board - we're ditching the original and going with a carbon dash board, digi dash and some nice push button switches - similar to this:

The amount of time spent on this project has been immense - mainly because everything needed re-doing. Should be great when its done though.

I'll update with more pics as we go :)

now that looks mint, definitely the way to go too with the strip down, that loom looked a right mess,

are you making a whole new loom?

Yeah, pretty much - we'll use a std Nissan engine loom but modify it for the Westfield chassis. Then hopefully tidy up whats left of the Westfield lighting loom and modify as appropriate. Going to try to hide away most of the relays and fuses etc so it all looks neat.

Nice work:thumbs:

What sort of power are you going for?

is it still on stock management then? be a shame not to fit something aftermarket. they always seem a lot neater

It'll be 250-300bhp. The owner hasn't driven on track before so it should be quite funny to watch. Might have to wedge the wastegate open initially. Even at 150bhp it'll be 300bhp a ton...

It'll be on standard management - it'll be adequate for now and still be pretty neat.

That will be more than enough, 150bhp makes for a quick 7 type car, 300bhp makes them VERY quick!

I'd love to do something like this one day. How many hours has it taken so far?

I thought the idea with kit cars is to have a light engine? Is the SR suitable?

Not sure to be honest - I think it'd have been quicker to built it from scratch.

I don't really know how the weight of the SR compares to other more conventional engines. Probably not a huge amount in it and having almost double the power of the NA engine will help.

I'll get it on the scales when we're done.

Has to be around 10hrs at least I guess?

If someone was do to this in their spare time I guess it'd take many, many months.

LOL - more like 100.

Oh right lol :eek:

I didn't see the sand back chassis bit. :o

Or the engine rebuild bit :)

Everything takes ages because so much is custom made.

Yeah, that too. :o

Think I'll re-read it again when I'm awake. :nod:

some nice work you've done there
I assume that's your new engine mount vs what it came with - can't believe someone would make that and think it good

looks like it was made well initially and whoever decided to fit the SR afterwards wasn't really up to the job

Cheers - most of the credit goes to Kyle though, he's been doing the majority of the work :)

Yeah, new and old mounts

Very impressive. I bought a westfield last summer with a poxy little 1.7 ford cross-flow, this thing will be fing immense.

I've often thought about dropping in my 300bhp ca from my old s13, but as you said about the radiator, was allways worried that i couldnt get a bigger enough intercooler and rad in (that and not haveing the mechanical skill).
I allways thought if i did it it would probably have to have an exposed airfilter as you see on a lot of the 7 cars, pretruding from the bodywork. Is the positioning of the air filter in the pictures the final positioning? if so you're obviously confident it will have enough cold air flow positioned there?

Dans old westfield? If so remember going out in it running a pretty much standard SR and was the quickest thing i've ever been in! Cant begin to imagine what it will be like with more power!

It'll prob be a little higher than it is - not made the brackets up yet. Even if it is a bit warmer than ideal it'll still go bloody well.
