Tigra x16xe -> rebuild by LBperformance Bulgaria

[Method3288]

hello mates .. decided 2 share my project with the migweb forum

started 2 do myself a mantzel copie .. posted a thread in the forum .. but things didnt go like I expected with my work on the project so I take the car 2 the LowBudget performance team ... this is what it happened

I dont have fancy aftermarket parts like SBD because the budget went for rebuilding the f**k'd up ecotec :/ and it was done what it could with the stock potential

specs:
.intake
-custom made intake manifold with trumpets
-x16xe lower part of the intake/runners ported 2 fit the head intake ports
-bigger throttle body from x18xe ... ~53-55 mm
-cheap cone filter .. till i can buy a panel one 2 fit the tight space
.exhaust
-custom made 4-1 manifold 45mm runners 63mm straight pipe with 1 silencer .. no cat
-thermo isolated
.headwork
-port polish .. about 10mm in diameter
-polished valves
-some headwork 2 rise the compression ratio
-the stock exhaust cam was replaced with intake one .. so now is running with 2 intake cams ..
-new head bolts
.block
-polished pistons
-new rings goetze
-all bearings changed with new ones
.ECU
-map on a aftermarket forum bought 7.3k rev limited chip
-new lambd sond
.fuel
-3.6 bar on the fuel rail
.OIL
-YACCO Galaxy 15w50
.EGR system- out!

still breaking in the engine ... dont know what kilometers i must wait for it is okay to take the car to 7.300 rpms .. I'm afraid 2 push her hard because it isnt gonna be pretty if things go wrong ... now i have 750 km on the clock .. (cylinders havent been touched)
the car gave a monster consumption of 10l / 100 km on freeway driving (maintaining about 3000rpm) and 15l/100km city driving .. max 4000 rpm so i switched of the lambd senzor and leaved the car runing on the MAP schemes ... consumpion did go down .. but not enought ... :S around 10l/100km city driving ..
the car pulls quite well .. little mood on the low revs .. but after 4500rpm the things changes ..


still 2 go: lightweight flywheel ..
DYNO

what performance do you estimate from this conception of the engine ?

[TigraTurbo]

Good luck with ur built! i would say 130-135 hp

[Method3288]

yeah .. i am hoping for 130-140tops ...
this things with the hp-s doesnt work the way most ppl think .... chip 10hp + intakebox 20hp + exhaust manifold 17 hp + cone filter 5hp + straight pipe 5hp + port polish 10 hp + nice paint 1000 hp = veyron

[TigraTurbo]

dont worry about numbers,if it satisfies u more than it used to,then u're ok,the thing is that u get used of horsepower quick

[Method3288]

like I said .. nor now she can't satisfy me like she can .. cuz i fear not to f**k u the ngine .. but it's like vtec after 4.5krpm the pull .. the sound ..

[TigraTurbo]

I know believe me when i had it 1.4 with mantzel/schrick cams/full supersprint ex,etc,etc,......ure right,it DID sound 99.9 like a vtec,just less hp

[Kev_G]

ill be looking forward to this & to be honest the little ecotecs do work well with power boxes etc

[Method3288]

for now .. on performance level .. this much .. when i have extra cash .. will go for daily driving cams .. and lightweight flywheel .. but before that ... maybe brembo 236mm discs + brembo braking pads + calipers from .. astra maybe ... dont know .. must be something bigger that will be bolted on without modifications on the chasi

[Kev_G]

why dont you go to 256mm brakes off a astra GTE / GSI? nice looking car

[V37_Redtop]

Really like this car, never seen anything like it!!

when you put the intake cam instead of the exhaust one was it on the same timing mark's? and also is it worth doing it to a stantard x16xe.

[Method3288]

i can't tell u if it is on the timing mark .. you will have 2 synchronise it .. i think it goes half tooth back .. but i can't say 4 sure ..
is it worth doing it .. 1 friend told me that the exhaust cam is smaller from the intake .. so I bought an extra stock intake cam ... when i opened the head .. it turns out that they are almoust identical ... some of the 1.6 engines have different intake/exhaust cams.... dont know which exactly .. mines were the same ..

[TigraTurbo]

had done the same cams on my stroked 1.8 motor,and it felt really good,but dont have any dyno print outs to compare...

[cosmin_cosmin_1]

are you running adjustable pulley for the exhaust cam? i'm interested of the intake cam mod, havent heard about this before

[DrewyCoupe]

nice tigra mate nice colour

[Method3288]

no.. stock pulleys , the intake cam is the same as the stock .. i thought that the exhaust and the intake cam are different in stock condition .. but it turns out , that they are the same on my engine .. so in generally .. i bought a cam that i didn't use nice ah ?

[Method3288]

ok .. so this video shows the car running with the 1.8 throttle body from 1.8 ecotec .. .. that throttle body was with f**ked up TPS sensor , and the MAX indication that we get was 60% open throttle this means that on the video the car is runing on MAX 60% and that is under question mark becouse it is with unluged lambda sensor ...
becouse of that , i was forced to look for a other throttle body .. witch had to be from GM engine 1994-96 year and must be bigger then that one .. so i went with the tbody from 3.2 V6D1 engine .. isuzu trooper / opel/vauxhall monterey with ~68mm diameter .. > and propper TPS .. i hope ..
*the other mod on the car is new lambda senzor , mounted on another part of the 4-1 exhaust manifold .. the reason for that was .. the wrong data that we get from it ..
*other mod is upgrade of the front brakes 256-> 280+mm disc and calippers from fiat coupe 2.0 > which doesnt goes in the stock tigra 15inch rims , so in the winter i must find another 15`rims or 16`...
for now that's the update with the project .. so .. stay tunned cuz tunning never sleepZ .. i hope soon everything to be in order and get a dyno results
