XE Tuning

[ant_tay]

Hi guys/gals

Pretty soon i will be looking to get more power out of my XE i will have a budget of £1500- £2000 possibly more can anyone suggest what are the best products for the job and NO TURBO

Thanks Anthony

Throttle bodies :D

[ant_tay]

was thinking Throttle bodies but i want more and any other routes i could take

[Big_Chap]

keep an eye out in the for sale sections on vauxhall forums, good condition used parts will save a fortune, throttle bodies, btb/SBD manifold, new cams & new vernier pulleys and conrod rod bolts can be had for you budget, that's what I did

[Jack]

LSD? Ok so it won't up your pub horse power, but will effectively make your car faster through usability.

what he said i would be more than happy with that 200ish bhp

[ant_tay]

i was thinking about boring out to a 2.1 aswell i will be buying a spare engine for all this work to be done so the time frame to get it done is not important and will be able to gather more monies to what i want

[blue_peg_16v]

throttle bodies, would be the route id take to start with

[philip]

buy yourself some arp rod bolts and tbs to start.

for £2k thats about all you will get, unless get bodies, loom, ecu 2nd hand.

dont get conrod bolts or conrods that have been used, otherwise there chance they will **** themselves.

you could use: tb's, q38h cams or q42h cams with pocketed pistons, arp rod bolts, decent manifold and head work and see a gen 200-210bhp or so, over that look at doubling what you want to spend really. ive got £6-£6.5k in my xe and thats going for about 250bhp!


o you could also probably use 100bhp of nitorus on a stock xe :D

[ck]

full rebuild, a set of r1 carbs maybe, which would then leave plenty left over for an L.S.D some cams and rolling road time...

how does it drive with that going through the front wheels?

ill be wanting to uprate my XE at some point, but i wanna see if it excites me as it is first

bin quoted £3k fom bodies with independant ECU set up with about a 30BHP gain ?

and about £6k for full rebuild and like uve mentioned above and about 240/250 BHP but surely thats too much for the baby vauxhall, but please tell about urs

[Sloth]

id happily lob a n/a 250bhp xe into a nova, just use the correct suspension and brakes and gearbox, and youll be ok.

[philip]

cars not finished yet and its not fwd:thumb: - well sort of lol


if want a motor building/speccing let me know, i do all own engine building, head building for myself and local lads.

£3k is quite abit tbh matey. ill give my mates a ring and get a rough price off them.

but if want anything just drop a pm and see what can do:cool:

[Sloth]

i got quoted for tbs and standalone, £2k. id also fit n.o.s aswell just for a giggle...

[geth_xe]

turbo?

[Pistol Pete]

Read his first post...


and NO TURBO

:)

[geth_xe]

Read his first post...



:)lol i must have missed that part

[Adam]

Fit some ARP rod bolts, and 100hp nitrous through a controller.

If you want good power NA then you really need TB's, or inferior twin carbs....

[Will F]

Always makes me chuckle when people quote power figures for XEs, especially 'modified' ones! lol

With decenbt TB set up (£1200 2nd hand with management) and mapping £400 and a decent exhaust manifold £300 (2nd hand) you should see a genuine 185 ish, which is more than enough for a relatibvely small outlay.

There is no way you will get anywhere near 250 for £6k, unless you buy all second hand I suppose, but then you risk reliability/who did the work etc etc...

The engine I have cost in excess of £14k and is reliably 240 ish, which is lovely! ;)

[ant_tay]

i aint got a clue and wouldnt want to guess or know what my engine is running at atm but i know it aint gonna be 150bhp

[ant_tay]

Adam just to let you know i got the exhaust fitted and it sounds realy nice and fits perfectly and i didnt know it was a scorpion system either but any thank you very much again

[ant_tay]

if my engine had the 150BHP what would the gain be from TB's

[Will F]

20 - 30 bhp depending on manifold and exhaust.

[ant_tay]

thats not alot considering its 200-300 to get the car chipped and get 20 ish out of that and a cam bigger injectors and possibly NOS

[philip]

will - slipper pistons, steel rods, crank, newman full race cams, dual springs, caps, solids, wasted valves, qed dth bodies, s60, tony law fold and 2.5 system, etc etc, im pretty confident i can get near to 250.:thumb: evreything was new except the bodies...you justy need to know the right people.

i do all my own engine building, maching, porting etc, so im gona save a hell of a lot than paying someone to build it. you also end up paying for the name too despite what people or yourself will say. its a fact, just to say ive had my engine built by sbd, qed, jre (besides the potential reliability factor

im guessing you have the toovey motor? before commenting, try and find out a little bit more first matey:cool: if you have the toovey lump i thought that was 2nd hand?

[scott.parker]

Chipped ECU's are balls! 2-10 bhp max gain..

A remapped ecu is better (with all the right complimenting parts, eg exhaust, manifold, filter-induction) you could maybe get 20-25 bhp but that's still going to coast £400 for the remap, and allot more if you don't have a good manifold/system/etc.

2ND hand independent ecu and throttle body set up, with the right manifold and system is the way forward.

My engine use to be 165bhp it was rebuild xe with standard manifold and a 2" system and ITG cone filter into a powercap and ARP rod bolts, we rolling road-ed it at a reliable place stealth racing of southam http://www.stealthracing.co.uk/ we did several runs, and on one run we tried a Courtnay "chipped ecu" that was ratted to 20bhp gain, and it gave 2bhp @6600 rpm :roll: totally pointless in bhp terms, but it did drive on the road a hell of allot better, so it's not always what the power graph shows, it can be felt/seen more when driven on the road.

Anyway, my engine now has sbd TB's mbe ecu, sbd manifold JP system, quaife diff, it's using a "standard map" I'm quite confident to say it's 180-185 bhp

And i can tell you that on the road it's more then enough this sort of set up is in a light FWD nova.

What are 'race' cams? Whats the spec?

Steel crank too? What are you expecting to rev it to then?

What compression are you running?#

And yes, I have the Toovey motor and I have receipts for £14k for initial build, plus 2 freshen ups which were half that - twice.

Hope that's OK?

[Will F]

thats not alot considering its 200-300 to get the car chipped and get 20 ish out of that and a cam bigger injectors and possibly NOS

PS that IS a lot of bhp/per pound for an N/A lump.

Like Scott says, Chips, Filters etc wont really do anything.

[philip]

valve lift In Ex Cam lift In Ex

11.80 11.75 11.80 11.75

0.465 0.463 0.465 0.463


newman cams. kent never seem to be anywhere near what they qoute. dont rate piper either. might go for some larger cams again next year if stick with the XE

running 12.5:1, only want to rev to about 8.5k, and its for a road car.:cool:


half that price for freshen ups - glad i do all my own and dont have to pay anyone labourlol what specs the toovey lump? anything like giles' xe?

[Will F]

12.5:1?? Whoa! I would have thought that isnt necessary for 250?
Neither is a steel crank, but if you have one lying around - fill thy boots! XE OE cranks are good to 9k all day long.

Well they werent £7k, but due to the slippers making the bores oval the first time, the first was more of a rebuild....

Kent and piper are a bit hit and miss, but cant see why they wouldnt produce the power? They are bits of measured steel at the end of the day! lol The problem I had with them is that the lobes wear uneavenly.

My spec is as much as I can go on 4 injectors - and my cams are restricting me a bit, but I dont want to rev it more than 8.5k really.

What injectors are you using btw?

[ant_tay]

i think it would be more cost effective for me to go turbo then me thinks

20-25 with just a remapp?

my c20xe:

-280* dr. schrick cams
-lightend flywheel
-60mm stainless steel exhaust
-dyno remapp (with limiter set at 7600rpm)

total outcome: a good 170ish HP. i'm loosing some horsies due to running with stock timingwheels (correct word? camwheels?) so i cant adjust my cam timing. with them, and remapp again, i most likely be looking somewhere near the 180hp line.

ant_tay: whats the deal with bigger injectors? OEM xe injectors are capeble of more then the give, a remappe engine with cams doesnt need bigger injectors. hell, when running 250hp from a XE (no turbo,nitrous,compresser, the thing was all motor) G60 injectors are doing the job.
