MX5 engines, restoring and conversions.
The MX5 is based around the idea of the driver being at one with the car (Jinba ittai togetherness), it is main reason we love the MX5’s at Basset Down Balancing. Yes, there are faster cars out there. Yes, there are higher specification sports cars out there. However, when it comes to driverbility and fun factor, the MX5 does just that. The two main parts of the car that in our mind, needs upgrading is the suspension performance and the Engine power. We offer a multitude of areas to improve on. Scroll down and take a look.
A focused damper package is a must have. Our brand of choice is Miester-R, we find them to be priced right and overall a very reliable unit. Most importantly, a great looking upgrade for your pride and joy.
For those who only need a small jump up, which is based around the stock ECU. It’s ideal for a stock MX5 hill-climb/sprint championship. We see a average rise from 115bhp to 130bhp, with some help from replacement cams and cylinder head work. More if you decide too. This can be done if we use an after market ME221 ECU and remove the air flow meter.
This is our recon PLUS unit. We offer a standard exchange recon engine with H beam steel conrods, Cometic head gasket, Arp head, main and conrod bolts, boundary oil pump also, compression is 9-1 factory standard. This engine is ideal up to 300hp turbo package. We can offer this package with a higher compression ratio and some higher lift cams with ITBS. Which we can supply along with a ME221 ECU.
For the more adventurous out there. We offer the option of stage three engine builds with high compression forged pistons pistons, steel H beam, Conrods high lift cams and ITBS (from CAM EFI)and after market ME221 ECU. All plug in and play. This will slot straight into your existing car. At this point we can offer a range of options: different heads, cam profiles, adjustable cam pulleys and valve options. All tailored to exactly what you want to use the car for. All you need do is tell us your overall goal between 150-170bhp.
Stage 4 300-400hp
This is our turbo or supercharged engine package. The basic package is a recon exchange unit with a full reconditioned cylinder head, all new seals also, comes with low/std compression forged pistons, H beam steel rods, cosmetic head gasket, ARP main rod and head bolts or studs, boundary oil pump. This package is aimed at 300-400hp. We suggest we look at changing cams and valve springs, if your looking for power closer to 400hp. A full head port with 1mm bigger valves would also be needed. However, we can fit around your budget and aspirations, we just need to know what you hope to achieve.
Stage 5 1600cc MK1
This engine is our Mazda championship engine. This engine is a fully reconditioned exchange unit with a big nose crankshaft with 0.50mm, overbore genuine Mazda pistons and rings, crankshaft.

As with all of our engines they are run in on our super-flow engine dyno with power runs to prove power. Also, checking for oil pressure across the rpm range. This engine comes with a dyno sheet.
