CJ Posted February 24, 2012 Author Share Posted February 24, 2012 Stronger, newer spring, less prone to boost leak/creep. Newer design. For me, it's a £50 win. I like you Johnny - so much nicer than that jock bloke Quote Link to comment Share on other sites More sharing options...

Scott Posted February 24, 2012 Share Posted February 24, 2012 Stronger, newer spring, less prone to boost leak/creep. Newer design. For me, it's a £50 win. If it wasn't a budget project car then I would agree, as it is I don't. There won't be any boost creep with an EBC. The spring strength won't make any odds with an EBC and the strength and design also won't make any odds to the application. For me, in this instance, it's 50 that could have gone to the boost controller. As it stands CJ thought this item would do away with it's necessity saving him £150. As it stands it's cost him £50 with no functional gain over stock with an EBC. Quote Link to comment Share on other sites More sharing options...

That's what annoys me (as in annoyed with myself) as you are correct in saying I thought it would replace the EBC and therefore save money. Ah well, if that's the worse thing that happens this week then I will live with it. Quote Link to comment Share on other sites More sharing options...

It won't go wrong CJ as said it's a nice bit of kit, but for a stock tubby with stock-ish boost it won't really get you any closer to your goal. It's something to note when you are selling though Quote Link to comment Share on other sites More sharing options...

It's something to note when you are selling though It will probably come into its own later down the line as if past history is anything to go by, the chances of us keeping things stock-ish are pretty slim The great thing about this project is that it has really given me a new lease of life, which considering my circumstances sounds rather strange, but I am sure you know what I mean. It is great getting back into the sourcing and planning of parts and the design of body kit etc. Josh and I are really loving it! Quote Link to comment Share on other sites More sharing options...
CJ Posted February 24, 2012 Author Share Posted February 24, 2012 Well, hold on. That Forge actuator only has a single port output on it, direct to the wastegate. Boost control solenoid sits inbetween. The stock one has two ports. One does the same - goes to the wastegate, the second port goes to the VSV for the cold weather boost adjustment - and when you fit a Boost Controller, it's a best practice to seal it up. I'd keep the forge actuator with a 1bar setting on it, Col - then use the Boost Controller to run it up to 1.25bar. After re-reading this am I right in thinking that the Forge unit will set the boost to 1 bar and therefore negate the need for a boost controller as I will only keep that as set and had no intention of going bigger? If I utilised a boost gauge to keep an eye on things (which I would do if using an EBC as well) would that offer some kind of insurance?

johnny g Posted February 24, 2012 Share Posted February 24, 2012 It would offer some. Just be careful and make sure you take the boost pressure reference from a good source. AJ will know what he's doing. Quote Link to comment Share on other sites More sharing options...

It should work fine, it'll be like a manual boost controller though so it will change depending on the weather Quote Link to comment Share on other sites More sharing options...

garethr Posted February 27, 2012 Share Posted February 27, 2012 I came across this the other day, and thought it might be worth noting: http://www.mr2.ie/mr2-forum/27-conversions/40370-gazs-mk2-big-brake-upgrade I completed this upgrade on my car a few months ago, and have since sold a number of kits to allow others to do the same. This allows the fitment of bigger discs on the rear (Mazda RX8 front 323x22mm) but keeps the stock rear (Rev2+) calipers, and allows the fitment of bigger front discs (Supra Twin Turbo UK spec 323x30mm) and Nissan 200SX S14a 4 pot calipers. The brackets are CNC machined from a solid block of aluminium. The reason I chose to base the kit on these calipers, is because they're relatively cheap and easy to find. The 300ZX and i've been told R32 GTR calipers also fit, as they share the same bolt patterns. Quote Link to comment Share on other sites More sharing options...

TubbyTwo Posted March 2, 2012 Share Posted March 2, 2012 It will give you advance warning of when your turbo seals are going by leaking oil out all over your engine bay? Actually now you mention it, I seem to remember the stock valve doesn't seal closed until it sees a certain amount of boost pressure, much higher than aftermarket ones. So if you're modulating the throttle a bit you won't see boost. Aftermarket ones seal as soon as there's no vacuum (i.e. positive boost pressure) so you get on boost a milisecond quicker, but you might sometimes get some small amount of boost when you don't particularly want it. Yeah im pretty sure that the stock recirc doesnt seal when off boost, allowing air to pass through both the turbo AND the recirc valve helps a bit off boost. The OEM recirc does make some turkey honk noises once all the stock intake boxes are gone Quote Link to comment Share on other sites More sharing options...
CJ Posted March 6, 2012 Author Share Posted March 6, 2012 Due to me cooking my engine over the weekend (and warping the head ) the swap has now taken on a more urgent aspect and so I am sourcing and buying parts accordingly. One quick question I have is regarding spark plugs. I will be running 1 - 1.1 bar of boost and was thinking of putting in the BKR6ES or slightly colder BKR7ES copper plugs as I don't think there is a real need for iridium. What are your thoughts?

Guest toxo Posted March 6, 2012 Share Posted March 6, 2012 7's, don't bother with iridiums. I would advise you get all sections of the cooling system checked out for leaks BEFORE fitting the new engine, unless you know FOR SURE what cooked it. You don't want to cook the new one too, and all it takes is a pinhole in the radiator or a leak from the hoses over the fuel tank. Quote Link to comment Share on other sites More sharing options...
CJ Posted March 6, 2012 Author Share Posted March 6, 2012 Thanks Toxo - and good advice regarding the leaks. I spoke to Alun last night (AJ Engines) and he said the same to me. Quote Link to comment Share on other sites More sharing options...
CJ Posted March 6, 2012 Author Share Posted March 6, 2012 Best place to buy spark plugs? Quote Link to comment Share on other sites More sharing options...
Guest toxo Posted March 6, 2012 Share Posted March 6, 2012 There are 2 pipes that go over the top of the fuel tank known in the MR2 world as the 'heater pipes from hell'. You can't get to them without dropping the tank (which I guess you would do anyway if doing an engine swap to uprate the fuel pump as there's no other way to get to it) and they can crack where their mounting brackets are brazed on. In case you haven't found it yet, the fuel tank is in the transmission tunnel When they fail it's common to replace them with a bit of 'normal' flexible heater hose from a motor factors - the same sort of stuff you'd use for a chargecooler install, slung underneath the fuel tank and then connected back to the cooling system at either end of the car. However if you plan to drop the tank anyway then it would be trivial to check them for faults. I buy my spark plugs from Toyota but then I have a trade discount which makes them as cheap as buying online, but without any delivery charges.
