just been sooooooooooooo F-in busy with work sorry everyone
I managed to get to a test and tune at the pod the other week for the coupes first outing, I broke it of course
I just thought that some of you would like to see/know the latest
Here are a few snaps from the first days testing only four runs were possible until I broke it
Nothing to do with the running up the strip, and should be a case of just remove and replace

Not bad for first time out, having only driven up and down the drive at 10mph, and theres plenty more to come, as it wasn't a full bore run
no nitrous either
Definetly in the right place it would appear from the specs you have posted above that the previous owner has forged the engine.
sorry for the war and peace reply and if i end up teaching you to suck eggs.
Pleae treat me as stupid, as I find it covers all bases when asking questions, give me
obvious answers and I shouldn't get confused
3sgte Rev2 engine is a good place to start due to it having thicker/stronger walls than the other revisions of 3sgte.
I had read that somewhere so thats a good start
Group A Crankshaft and conrods It is Possible he has had it lightened and balanced and forged conrods.
Seems silly to keep the stock rods when fitting forged pistons.
I don't recall asking about the con rods
](./images/smilies/eusa_wall.gif "Brick wall")
ARP bolts are the dogs danglies when it comes to engine building I dont know if they make bearings though its possible he means ACL bearings which are very good.
I didn't think they did bearing I thought I'd post just to put myself straight either way
Superchips programmable Ecu if you say it is a small slightly larger than a matchbox affair sounds like the ICON model.
The ICON is designed as an ignition only chip.
Basically it is able to advance
(or retard) the ignition timing so improve efficiency.
It works by fooling the cars original ECU into thinking the crank is in a slightly different position to where it actually is so tricking the ECU into an advance in ignition.
In an engine with a poor original ECU/ignition timing this method can show some improvements and the extra retardation for your Nos will be beneficial.
I have had a look at this and it has 2 LED's on it 1 red and 1 green.
It also has under the superchips logo the letters ABC in reflective blue, does this help with identification of this box?.
NGK Plainium plugs dont know whether that s just a typo from you.
NGK Platinum plugs need changing less often but with your nos and other mods i would still change them find out what grade they are as you could probably do with going a grade cooler with the Nos.
I will change these for a colder set when I get to that stage, but I have a long way to go before I do
Adjustable boost controller may just be a grainger valve fitted between the actuator and the inlet manifold in the vacuum piping.
look at the actuator on the turbo and follow the pipe back you may find one ther or you may find an electronic solenoid if it is the latter follow that to some form of electronic boost controller box will be about 1/4 DIN size.
What boost are you running with your stage one ct26 should be a max of 1bar.
I did get a squint at the boost level during a test and tune day and it read just, just over 1bar so maybe it needs backing off a bit.
I have had a good look and maybe I'm stupid but I can't see anything
HKS 272 camshafts are a good upgrade over stock retaining drivability but improving the top end.
do you know if you have vernier pulleys fitted?
I have no vernier pulleys
but I intend when I'm ready for the engine build to purchase a set
JE forged pistons are a popular choice amongst the MR2 turbo people having forged engines built.
with supporting mods you can run alot higher boost
I've used JE pistons before with pleanty of boost/nitrous with no problems
205cc I dont know much about but you say it has a small ice tank Does it have a rad at the front of the car but on cars i have driven with them fitted because of the shorter more direct charge route and the cooler charge temps achieved throttle response is snappier and boost comes on quicker.
I fitted the ice tank as a quick fix as I havn't sorted the front end layout permently also I don't have a cooler rad
TRD steel head gasket on the Rev2 3sgtes the Headgasket is one of the weakpoints over the rev3+ which have Multilayer steel headgaskets as stock.
good upgreade for reliability/increased boost do you know what thickness gasket was fitted as they come in various thicknesses.
I have no info on this item
(I thought it might be a thicker one for allowing more boost by lowering the compression ratio)
Fidanza flywheels are a common upgrade for the Mr2 turbo owners and are very good freeing up some parasitic HP losses.
Fidanza state a reduction of the flywheel weight up to 55 percent of the original, and reducing the flywheel inertia up to 80 percent of the original.
fuel economy suffers though through the lost inertia but tacho snapping is fun.
another good thing
(as per my past life with A series)
stage 1 fensport CT26 fensport state Ideal for cars running up to 1Bar boost, full boost available from 2,800 rpm, power up to 270bhp.
It does depend on what the previous owner selected for his actuator though as there is a choice of pressures.
I might have to research this in depth as I want more power when I do the engine build but I don't want lots of nasty lag
(the eternal quest as we all know)
Cat removed the majority of Rev2 engines were fitted to MR2s up till August 1993
"K" reg so you dont need a cat for the emissions test.
The previous owner may have just gutted the original cat or fitted an aftermarket decat downpipe.
You can pick up decat downpipes from lots of different places but there are a few out there which are prone to cracking due to poor design/welds etc.
The GTS chris/BERK decat downpipes are highly regarded as they have a flexi section and this appears to have solved the cracking problem.
Just at the drag track stage at the mo so at the 90 degrees bend it just goes straight out the rear of the car
Nitrous speak to i think its either Michael or Scott Barton they are both mods/commitee members one of them i cant remember which have nitrous fitted to a 3sgte's.
All knowledge I welcome as I'm sure the nitrous rules cross over but jet size and progressive rates help to keep your engine safe
( I just blew the sh*t out of my A series when the rules were pushed just that bit past what we all agreed was safe
)
5 speed box with LSD from memory The E153 box code should be followed by a three digit axle code.
735 and 738 refer to LSD-equipped E153's
Where is this code on the box
(I haven't looked yet but I just broke it a the pod, I can't seem to select reverse???)
uprated clutch without paperwork your guess is a as good as ours is it snatchy/grabby at all?
Its very very snatchy but the master cylinder is just a bit bigger than a standard Mr2 item
.
15" A539s Very good tyres.
Oldie but goodies
What are your plans for the car are you going to put it back to the road or is this going to be a track weapon?
Its going back on the road eventually but I'm trying to compete against a fellow GTM'er( the rival is the red coupe in the pictures above,)
.
we both work in F1 for rival teams and I chased him for a while on the strip he had fitted a Honda
when we were competing with A sreies, he had the 1.6 I had a 1293 turbo and we were evenly matched but he had the edge just.
then he fitted the B series V=tec
no thats just plane taking the pi**.
so brain stoming ensued and what better way to beat your oponent at their own game than to go bigger and better
Id love to come and have a look at it
as i had a GTM coupe with a 1340 mini engine and that was more than enough fun
that just sounds suicidal.
