the inlet is indeed one of the most restrictive parts the ma12 head is not to bad on air flow but to get the best from this a bit of head work is required but on its own should yield good results iirc kev got 75bhp at the wheels from his twin webbers and they never ran right which is a shame, still the proofs in the rolling road

nice work, good to see some unusual mod's. you Micra owners are quite inventive!
How about lowering the compression and getting it blown. a t2/4 would be ideal and could run with the carb well. you wouldnt need any forged pisteons just get a slightly thinner head gasket made up and get the head gas flowed. I would bet with a little tact the R5GTT system could be adapted.

I think you meant thicker gasket?driftworx said:
I'm building one MA10 engine during winter and I'm going to put Garrett T2 from my other Micra to it, because I'm atm installing T25G to it. I'm going to use Datsun A15 engine's carb with the MA10 and maybe make new inlet and exhaust manifolds. I did a little head work with the critical parts of the ports, but nothing enormous. Hopefully I'll get it ready in nexy year if I have some time to it from my other projects

Nice, well you should see some impressive gains from this. Keep us posted and please share any findings you have Mark!

I already have all the information I need, I have sources for all the tuning parts needed for my K10,
I know people who have built/race engine K10's who actually know what there talking about, unlike some who have never done anything to there's and think they know it all.
Either way if anyone wants any information then add me to msn messenger and i'll gladly share findings or anything.
Lastly I dont need any proof from a rolling road, all i have to do is sit in the drivers seat and put my foot down to know how fast my car is.

The car will be going on a rolling road because it will need the carb setting up.
If Kev's old one litre ran 75bhp at the wheels and it wasnt running right then why is it apparently impossible to get 88bhp at the wheels with a 1.2 race spec engine which obviously is running right?

No it didnt. Kevs old 1.0 was not anywhere near 75bhp@ wheels.
You cant break the laws of physics Mark now matter how much you say you can. Infact I've never seen a rolling road print out of a normal K10 1.0 or 1.2 that has even looked slightly realistic. They always have totally unrealistic cost down losses that wildly exagerate the results as the MA10 and MA12 engines produce relativly so little power.

i took the inlet manifold off my 1.2 yesterday and can honestly say the inlet is of crap design if you want to get power out of it, its fine for 60bhp though.
the ports on the inlet are smaller than the head and dont match up correctly, the head dosent seem that bad for a 1.2, im sure the head is not a restrictive part of the engine and noone will out flow the head when tuning a N/A engine, on the other hand a turbo MA will struggle

from my experiances the k10 1.0 and the k11 1.0 there is no diffrence whatsoever, to be honest a k10 1.0 high comp would beat a k11 1.0
ive drove a standard 1.2 k10 but not yet drove a k11 1.3, remember the k11 is heavier than the k10, there probable aint much in them to be honest and i wouldnt be surprised at a tuned up k10 like marks beating a tuned up k11, the k10 is going to have quite a bit more low down torque than the k11 due to the fact it being a 8 valve also the power to weight will be better.
to be quite honest though if you want a fast car buy one in the first place, k10's and k11's arent fast imo, thats with the standard engine's, im not going any further than dropping in a ma12 in mine, tuning that engine would be a waster of time considering all the money i would have to spend on it, it would be more benificial saving up my money and put a diffrent lump in there that responds well to tuning ie a turbo lump like a ca18det or a sr20det.
i do take my hat of to thoes that have squeezed every extra BHP out of there little MA's and CG's

I am in the situation where I cannot drop another engine in my k10, I would if I could but I could not do it myself and nor do I have the money to do it all, the K10 super s is possible my favourite car and I don’t want to change it for a faster one just yet, if i made a list of all the parts I have bought to tune it up then you'd be suprised how little i have spent

i recon we should do a k10 V k11 challenge down the pod and see if im talking out my arse lol

The last two times I went to the Santa Pod meets I was the only K10 running, apart from the super turbo so it was k10 v k11 the whole time,
What we need is more k10's running, I hope at the next santa pod arnold, elliot and Micraman will be running as well as myself which would be really good

I couldn't do the 16v 1.0 K11 in my K10 previously (without the kit) although i did have an exhaust that was killing off my top end revs, lower down it was much quicker than with just the stock k10 exhaust (IMO) but obviously with my high revs being non-existant and the K11's being that much higher output at higher revs it killed me after about 3,500rpm.
The car's finally in the workshop so with the sr20 lump i should be munching on Nova's all too soon

Must say I am impressed with the progress you have made. Make sure you let us know how you get on and where you actually get all these bits from lol. Looking forward to seeing the power outputs of this... and yes next year I should be running. Nice to see that moving along too Batch.

Lads I dont mean to #### on your parade but that looks to me like a Escort RS Turbo manifold which flows like a bag of #### naturally but which isnt an issue since this manifold is usually force fed. The SU carb is old and a bit crap. Why not use a Nissan based manifold? Im not too impressed with the way the standard manifolds flange face has been grafted into place theres bound to be a restriction inside unless you extrude hone it to get rid of any imperfections.
In addition since when did adding more fuel ONLY make a performance difference? Surely you need to be thinking about improving the air flow through the head not to mention your valve lift is going to be the same unless you fit cams to increase the lift amount to then allow more air in to the engine.
I could be wrong so I will await the Rolling Road Before n after results.

gartracs2 i have already thought about improving air flow
I already have:
piper 270 cam
4-2-1 exhaust manifold and full stainless system.
I cannot make an inlet manifold myself in a million years so i bought the only one that was for sale, I've never seen another forsale so its not as if there widely avaliable, The SU carb came with it so that is what i will use, the manifold is off a class 2 autograss race car so has been used before and compared to the standard manifold it is a vast improvement.
inside where it has been welded has been smoothed out and there is no restriction

if you saw the standard manifold chap you would think the rs turbo manifold flowed like a fine wine at an italian restaurant lol the standard inlet is like trying to drink a thick milkshake through the worlds smallest straw lol. it is the most restrictive part of the cars system, but then saying that its also what makes the car economical....

LOL relax lads didnt mean to cause upset, but to be honest I think its a bit of a turd effort myself, like I said lets see the results as proof. Lads ive been tuning cars for 10 years, Im currently working on Skylines and supercharged 350Z`s at MidMo, after being headhunted by themselves enough said I think. I work with Elliot. PS Arnold I love the Welding runs !

they dont mean anything anyway,,best way to see an improvement is a 1/4 mile before and after ,,and like you said before mark,you will know yourself just from driving it how much difference it makes
but saying that,,some people say they feel alot quiker from a k&n ,lol
