Rebuild Prices

[scottee]

Hi Guys

Just a bit of advice. Pre CAT damage to my 1zz, so i've had a price for a rebuild. Im just wondering if this seems alright, or if I can get parts cheaper somewhere else:

big end bearing set 43.00
main bearing set 45.00
complete gasket set for engine rebuild 144.75
new head bolts 30.00
pistons 200.00
rebore 100.00
oil filter and oil 25.00

Which comes to £587.75

Then £525.00 labour, Total £1112.75

Sounds about right to me.

Have you considered upgrading the engine while you're at it? Tuning parts aren't much more than stock parts, sometimes even less.

Thanks Tem

I was looking on MWR before you posted hehe. I seen the wisco pistons on there for about £240

[markiii]

bear in mind they wil need to use slightly oversize pistons duie to cleaning up teh bores.

[scottee]

I assumed it would be sleeved?

[markiii]

I beleive Toyota make a couple of different sizes to allow for honing teh bores.

we are only talking a couple of mm at most, I looked into a 2litre overbore a couple of years ago and had that interesting discussion with the insurance co.

might be worth checking how Toyta would plan to do it, and if sleeves are available

in principle either should work

It won't, unless you want to.  s8) s8)

"rebore 100.00" sounds like the price for basic reboring. The sleeves themselves cost extra and the work required to fit them will be more than £100. I'd guess closer to £500 or thereabouts.

I assume you are showing us the quote for JUST for the engine. The replacement of Main Cat and whatever you are doing with manifold is extra, because they must be done as well.

Main cat and manifold has already been replaced... well the manifold pre-cats have been gutted, and i have a sports cat fitted now  s:) s:)

[scottee]

I've just mailed MWR with a list of parts and see if they can get a tidy price including shipping on them. ah well, almost got the mr2 back on the road now! hehe

I think its a very good price after paying £730 last month for a head gasket!

A veritable bargain! The rebuild on my TVR V8 (by the previous owner I may add) came to an impressive £5,995!  s:shock: :shock: s:shock:

[markiii]

good god, I take it thats not a standard rover engine then  :-) :-) :-)

[scottee]

£5,995?!? bloody hell!

Atleast my rebuild will be done ready for my ring trip next year  s:D s:D

That's roughly what it costs to fix a blown engine at Toyota too. 3rd party companies can't charge that much, or they would be out of business.  s:lol: :lol: s:lol:

The rebuild was done at TVR Power in Coventry; these guys built ALL of the RV8's for TVR. They were sourced directly from Land Rover at Solihull, the stripped, gas flowed, port & polished and vast amounts of parts were swopped for uprated items. Not exactly the standard 3.5l V8 that left the LR factory  s:) s:)  
As it was Power that did the build, it probably explains the cost - there are a few 'indie' RV8 specialists who would most likely have been cheaper.

scottee mate,

Are you running NA or turbo? If you are the former, changing the pistons and/or touching the bottom end would be the last thing you would do. Stock piston and block should be good for 200hp or so, and unless you have an aftermarket ECU, upgradess like pistons and cams would need tuning. Turbo on the other end would benefit more from internal upgrades especially the conrods and pistons, which I think (rods) are the weakest link in any car.

Thus it is my good old conservative/thrifty opinion that if your 2 is stock, it's very likely you would find the upgrades overkill.

Thanks Simon  s:D s:D

The guy just mailed me back with this:

they would be oversize pistons because of the rebore either be
0.5mm or 1mm oversize depending on how badly the bores are scored i
will ring u on saturday if thats ok to discuss timescale and the clutch
if u want me to do the job or not.

Bearing in mind, I have very little knowledge on this, if it was to be rebored by 1mm, would that mean the engine capacity would be increased above 1800cc? If thats the case, in theory, its something that the insurance company should be informed about, or is it just a tiny difference?

Thanks for all the help so far, its appricated!

scottee,

I'm trying to save you some quids since obviously while I was severely addicted to modding the 2 back when I got it 2 years ago, I had the same urge as you to do anything and everything that seemingly looks cool and *ideally* adds power to it.

However, the sad but true fact of NA modification is hindered by the cost because the power/cost ratio is a bloody nightmare unless the name of your pet is called VISA. Sleeving is redundant for NA rebuild unless you wanna go overbore and increase your engine displacement. For street driving, "overbore" is overrated. The 1zz bore and stroke specs are 78.74mm x 91.44mm just for your information.

The formula for engine displacement is this:-

displacement (cc) = bore x bore x stroke x no. of cylinder x pi/4

An increase of 1mm in bore would net you a total of 1827cc.

and the theoretical increase in power due to this increased displacement would be 3.3bhp. That translates to 2.7 wheel hp. You do know you need to send your short block bored and sleeved right?? Who is gonna do it for you?

But if you truly wanna go overbore which like I said is not practical for our engine NA or turbo otherwise, then yes you would need to inform the insurance company.

I sincerely hope you would think twice though. In my utmost honest opinion, changing brand new OEM parts should be the end of your story, and spend the better half of your time driving your 2 and calls it a day!

EDIT: I edited the figures since I've made some calculation error.

Hi Simon, aprt from the the rebore/pistons, i think everything is OEM. Like I said, i have very very little knowledge of all this, and im just letting the guy whos working on it do what he does best lol. I jsut want my car back so I can drive it this summer. I havn't asked for any thing to be done to get more power, but from what hes doing, it looks like it might be a by-product?

A rebore will require new oversize pistons. Watch out for what they are quoting you mate. If your wallet is bullet-proof enough, I say the choice is yours.

If your engine damage warrants a rebore, then do it. If not leave it.

[markiii]

piston price will be teh same as stock kore or less, toyota make 3 sizes precisely to cover this scenario

it's standard practice to slightly increase displacement when honing the bores to remove damage

[Anonymous]

Stock compression I believe, else it needs a retune.

So you still using Toyota pistions eh Mate?

Hi mate, just a quick question, where are you getting this done? As I have had a quote for a rebuild and it stands at 3k, so if i could get one done at this price, it may be worth some investigation. Thankyou.
