keep the XE.

Turbo's rule man, but getting a LET in a Nova is feck loads of work & $£$£$£.
You may aswell be out enjoying Xe power, not scouring ads for mechanical drive F28's, equal length shafts & chopping gear linkages to clear steering racks & scratching your head over pipework blah blah.

But the sound of a set of carbs or throttle bodies is just orgasmic :p

Not for a month or so ...................
I'm in the same boat but every time I think about the hassle involved putting a LET in I change my mind.
N/A is the expensive way of going slow btw. lol

let's do look like a lot of work, but could a lot of fun as a result!?
I'd say LET as XE's really aren't all that but I expect to be shot down for that comment. Spend £300 on Phase 2 and fmic on the LET and have power and torque that an XE will never match!

or spend £300 on an XE thats ready to go in....lol
General rule of thumb I go by is if your building a fast road or 1/4 mile car, go for a LET, but if you're building a track car, a tuned XE is the better option due to the thrashability and higher revs.
Purely my opinion :)

Thats how I see it Lee.
Turbo's always FTW when it comes to traffic light GP's.
XEs aren't that slow tbf, but once you own a car for a while you always want more power.
LET would be crazy on track if you can make it go round corners, watch this video:

I agree with that too, but in my opinion its also down to how you set it up, if you set it up purely for the 1/4 mile then that's were it will succeed, set it up for track racing and it'll show its colours on track. But I'd go for a good spec XE on track personally.
3.2 v6. best of both.
Is that before or after you drive through the corner and the xe/let goes round?
i honestly belive, if it is set up correctly and is done right, a v6 will handle as well as a let/xe

let had a tuned xe and the let is on a different planet, but agree with lee for track the xe was better

I cant remember who said it but either Dave or Linden Dixon said to me that the white V6 Nova was actually just as good (maybe better) handling than a valver (this one (http://www.youtube.com/watch?v=VWbRAt7NiBs))
and tbh if that came from dave dixon, i believe it.
Like I said, it was either him or his brother Linden. Both of which have had plenty of experience with Nova XE's LET's and V6's.

i wish i never took the xe out of my blue nova and put the let in it may still be on the road if i didnt
for every hours road use it will spend 5 hours in the garage beeing worked on (if you drive it to the limit and if you dont theres no point in having it)
There is another option!!
450 bhp let
space framed kit car inspired chassis
4 wheel drive:thumb:
it was dave on here the other week mate think he on a mission to show v6 are just as good or even better than let's but say that he on building another let now lol
I'm sure I remember Linden telling me before we got into the Vectra to go to York, but at 7:30 am I don't really take much in. Either way the point has been made, V6 Nova's are teh fewcha y0!

True that, I was stood at the bus stop a few months back when my car failed its M.O.T and I heard a car coming up behind me, just as he got next to me he let off the gogo pedal, TISHHHHH, I thought, awesome mate you have a dump valve +50 BHP fo sho y0, now if that wasn't enough he drove past someone stood at the bus stop on the other side of the road and did it in front of them.
I hope the old man at the other bus stop was impressed with the sound as I wasn't.

i had one on mine but that was because the standard recirc had to be welded up as at 22 psi it used to leak and i didnt fancy stalling an 18 year old turbo at a over a thousand degrees and spinning at over 100,000 rpm
not when its attached to a block ect that has cost over 6k to get to the spec its at
smart man /\
peg, yours was mint at scarbroooo that day, the noise was epicly ftw.
Spud, check your rep.
How very rude i aint a taker :p
One question, has anyone ran a F20 on their LET?
What would kill them? Hard launches?
ste porter
14-05-10, 01:18 AM
i went through about 20 f20 clusters i used to strip all the teeth of fith gear also i snaped 2 input shafts cracked a casing and abliteraited a diff which resulted in parts of it making a swift exit and embedding itself in the floor plan and lower bulkhead
it was usualy hard acceleration from about 50mph in fith that did it its when its using full torque
Even on a standard engine?
If I get a LET I want F20 so whats the things you need to avoid to make box last longer.

my firs box lasted 2 months on a standard engine then when it went i went phase 2 a big intercooler saab reds 2.25 inch boost pipes enlarged top hat and vxr actuater and after that i was fitting boxes as often as i filled with fuel then after i spat a rod i went silly steel rods woosner pistons 22psi with 28 psi overboost 9k rev limit hybrid turbo reshaped combustion chambers over sized valves bronze guides arp's everywhere multilayer head gasket ported head bigger throttle boby 2.5 inch boost pipes even bigger cooler ect ect and to be honest i was scared to use it properly as i was scared of it just shattering in the end i think it was only the fact the clutch was slipping that the box didnt go at pvs i even took a spare cluster with me ther though and about 3 days after it let go again lol
it doest realy matter what you go mate they let go when they want to i have raged hell out of it and its been fine and then on other ocasions they will let go under normal conditions if you want my advise get an f28 get it rebuilt and a diff fitted and put it all in together as you will only regrett it at a latter date if you want to up the power and you will lol

this is the box now on nobbyz v6 lol

tbf when i rebuild it i think it will get an f28 but thats mainly cos i want the 6th gear on the motorway
i honestly belive, if it is set up correctly and is done right, a v6 will handle as well as a let/xe
You could get it close, but you'd need to load the back up with ballast to offset the amount of engine thats in front of the front wheels, so ergo you'd need plenty of power to offset the extra weight, which then renders it a bit pointless imo. You could get one to handle well yes. Handle as well as an XE? Im not so sure.
End of the day, porsche managed to make the RR setup work, even though it really shouldn't, but then again they have a bit more money than us lol

Dump valves were briefly cool in the 90's.
No doubt the turbo is more powerful and cheaper (initially, before breakages etc) but I personally would be half thinking about it sh!tting it's pants every time I gave it shoe. When I decided to go tb's over turbo I said I wouldn't rule out going let eventually but after two years and no probs I'm still content with the way things are.
I ain't slating lets, just my view. But also some of the best cars on here are lets which tells you something.
surely if a LETs looked after properly it will only be as realible as any other engine looked after properly
you cant give an XE death/high revs etc everywhere and it will last, it will last longer (unless it lee lol) but it wont last
indeed. imo lets have a bad name for reliability as people expect to take them out of a 100k plus cally and fit straight into there nova and give it death straight away.
A conversion done properly with a full engine rebuild etc 'shouldnt' give any problems. Most common thing to go wrong is old sensors

lmfao
that would have been a quaife 6speed kit then.... NOT designed for big torque ;)
and at £250 I'd expect it to have stripped teeth since the kit new is £2Kish
is this the replacement for the Big/Small debate. booost vs Atmospohere lol
Despite no mech speedo, cable shift and hydro clutch, I'd really look at F23's
They are cheap, UBER strong and less likely to be shagged than an F28 (which even the newest one is going to be a minimum of 10years old, if not more)

Nail head, same money to same money the lighter car with better weight distributions and moments of inertia will handle better on a similar suspension set up, spend more, or push more expertise into a V6 and you can get it to the point of a lesser XE, etc etc. then once the money runs out and you're down to direct competition, it unlevels the playing field again.
I was looking at an f23 on a mates astra the other night. I like the idea of the linkage. are they 5 or 6 speed stuart?
5speed.
Cable shift is great imho. Less problems with floppy engine mounts lol, easier to route as you can put stuff where the rod would go etc.

This question has been asked a million times.. I had a Let for over 12 months as a daily, the gearbox (F20) lasted, no problems what so ever.
Mine was running a stage 1, with a FMIC..
Rolling roaded @ 245.5 bhp.
Now i have an XE Egg, i would swap it in a heartbeat for a Let.

had carbs sounded good but let peformance is on another planet in comparison, and rick has sampled it and wants the carbs as he says the egg is slow compaired to the nova it still will be even with the carbs so imo hes better off getting a let

LET all day.
You must do it right though. Big shafts (equal length of possible), hubs and c.v's. F28, Diff. Rebuild the engine, get a very good condition loom, make sure all the sensors are up to scratch and you should never have any major issues.
I tend to give mine a good thrashing when i'm out and it's the most fun you can have with your clothes on. Performance is superb, most cars just never come close.
Another question, is there any point having a LET without a diff? In the straights it should be alright but what about corners?
I've also heard a diff'd F20 on a LET wouldn't last 20 miles, is this true?

Depends on the box. You either get a goodun or a crapun. Jack has had a bad run of boxes recently, but my last F20 I had before I split the car just kept going, and Dave Marshalls Stage 2 LET was running an F20 with an ATB and as far as I know its still on the car after quite a few track days.

I've driven my friends Nova Turbo which is on an F20 with no Diff, and its not really any use until your in 4th gear. It "one wheels" and pulls you to the left.
I'm not sure if a Diff in an F20 would cause it to fail anymore than without.
I think it would cause it to fail quicker as an F20 will never break while the cars wheelspinning. If it has grip due to the diff it will put more strain on the gearbox, shafts etc.
N/A can be fun but pound for pound an let wins all day long for me. ;)
