snails ep91

So Good! keep the updates coming

this is a great build. very similair look and design ive gone for to be honest. can you give any information on the rear camber modifications youve done and how you did it? can you notice a considerable improvement?

no ones actually made one for the n/a from what i know

lovely looking ep82. This has always been what drew me into starlets. the glow up gt panel and the mk1 front bumper! really nice example you've got bud.

my bank account doesnt lol. I wish i understood it more to take on a more hands on approach but this is all a learning curve isnt it. Im hoping replacing the likely now 30 year old rx7 injectors with modern larger units will be a big improvement.

So ive had a message to say the car has been back on the dyno since the block to chassis earthing issue was identified. They have apparently leaned the car out and have now made 270hp but they do not like the fueling at this level and want to richen it back up and change injectors. I have ordered 1050cc injector dynamics injectors which should be here in the next week or so so will have the car remapped with these and hope it performs better. Im hoping its the current injectors that could be limiting the power but we will wait and see what happens.

Thanks for the link though very helpful!

thanks for the link though very helpful!

I am really tempted by one. another £500 to spunk on the car though.. anyone else invested with any feedback?

assume nothing ever happened with this..

I have my custom starlet ep91 exhaust for sale. Only selling as I have upgraded to a 3" v band system. This has seen about 1500-2000 miles in its life so has been used very little the flexi is in perfect condition. and has been dry stored on the car in between. its in very good condition and sounded great. quite loud on a td05 setup but nice and raspy and gave some really good pops and bangs. very Nice subtle tip at the back. Front and rear section is heatwrapped. never finished actually wrapping the centre section but this will come as is. Also has a wideband boss welded in for use

I had a new battery installed last year which should be capable from its size. when i gt the car back im going to look into earthing some additional parts to improve upon this. thanks for the tips. the car is going back on the dyno this week to see what impact the new thicker earthing has if any and then im purchasing some 1050cc injectors to see where we go from there. more money! We'll see what comes of it this week and ill report back.

pm'd

car was taken to get alignment done and there was a starting issue when left there. they got the vehicle back to the garage and investigated that there was an earthing issue. they have upgraded the chassis to engine earthing and it is firing up no issue now. they said they would have expected a misfire if this was causing a major issue when dynoing the car before but still, an issue has been found. we are going to run it on the dyno this week now there has been an issue identified and hopefully this could have been the problem we are looking for..

Im being told its holding 4 bar fuel pressure no problem, so im hoping it is an injector issue. im certain they are rx7 550cc injectors. but its been so long since i bought them i cant say 100%. im going to replace them to be sure. will send you a pm regarding those inectors mate. yes i believe they will have used their own lambda sensor but ill ask the question tomorrow. I have relocated the battery to the boot and have a large cable earthed to the chassis. its bolted to the area where the spare wheel would sit as that is where the battery sits. i dont know if this needs imp

Im going to discuss this with the mapper. i was told it was holding 4 bar fuel pressure consistently. I did have them cleaned and tested but that was in the build process and was some years ago. unfortunately i dont have any information more than that as was done with other works. I have a brand new AEM Lambda gauge and sensor with only 5/600 miles on it in the car. dont they also put their own lambda sensor in the car exhaust when tuning? this would be obvious no? its a walbro pump (i really cant remember which one but is uprated) but is quite old now tbh. pro

I was assuming similair figures, approx 300-330 with my setup, mildly ported head but standard inlet cams springs etc. good news on dizzy as wont change right now if not needed as added expenditure. ive never seen/heard of n/a fuel lines being different but just tryng to rule any potential issues here. thanks for your input. The mapper said the AFR's were where they needed to be and were good he mentioned over the phone 11-11.4 something like that. dont have info on injectors but can ask. got your pm and will respond now cheers

Hi mate, yes will keep you updated. this car has fought me every step of the way to be honest so im not even surprised with the issues im having now. just dont want to run the car if there is underlying issues causing it to be so relatively underpowered. your comments on the denso injectors. can you elaborate?

I also messaged Sacha at WEPR who i bought the kit from and he definately thought it was down on power. Mattwho is tunning it does say his rolling road dyno reads less than other but i dont know. the head i have is mildly port and polished nothing crazy but standard cams, springs etc. From what ive read over the years 300-330hp is achievable on standard head and inlet.. that's what i was working on really and wasnt planning at this stage going for a fully built head. I had considered coil on plug conversion to improve the ignition side of things but have believed that people ha

Matt at motorsport electronics who is tuning has clarified we are making about 245hp at 1.3/1.35 bar boost. Having spoken now with ricky at racetech as he has experience with high power starlets (my tuner suggested a quick call with him for his input), hes also advising that we are about 100hp down on power at this boost pressure so does seem to be an underlying issue somewhere here. They are going to do a leak down and smoke test to see where there may be a problem.. I had a greddy tdo05 14b turbo kit on the car before and this only made 190hp when tuned by them before covid. d

Thanks rob your reply is very helpful. I’ve referred this back to my tuner and they are investigating. they are saying it’s holding 4 bar fuel pressure and it’s stable so unsure really. the only fuel lines I’ve had changed is from the standard hard lines to the adjustable regulator to the fuel rail and then back to the hard line. From what the tuner has said this is 6mm like and should be adequate for what we need in this application? I would take your advice with the injectors Thankyou but just a little concerned about maxing the current ones at this level. I don’t really kn

Hi guys, My starlet was being mapped today and my tuner ran into some issues maxing out my injectors. Im looking to replace the injectors but looking for peoples opinion on what injectors to go for please. Im wanting to push for 300hp so was thinking 1000cc injectors would be sensible. I currently have rx7 550cc injectors which though they would be sufficient but obviously not. it made 215hp at 1.3 bar boost. upped to to 1.5 bar and made 240ish hp but maxed out injectors at this level. Brief spec of the car is; 4efte with forged rods and pistons - new beari

wiring looks class mate. Whats the purpose of coiling it like that?

definately keep it blue mate. looks great and a lovely colour. hope you get it on the road soon
