1.6gti Engine Setup

Recommended Posts

willmounsey

Evening all,

 

I'm posting this for a friend who bought a rally spec engine from LAD motor sport a while ago, now he's had numerous problems with this company as he paid for this engine in full and over a year later is still missing parts and having problems getting them from LAD.

He's now thought sod it and is going to source the rest himself but has a few quires, he's not computer minded at all thus why I'm posting on his behalf.

 

Please bear with me as i know very little about engine's and tuning.

 

LAD wouldn't give out the full spec of his engine (or what he got from them) and so what is written below is what he's been told by them.

 

His engine spec is:

 

-1.6 gti engine

-bored to 1600cc

-Ported and polished head with 3 angle seats

-10/11-1 CR (they wouldn't say but he's guessing 10-1 CR)

-Rally cam, 305inlet/295 exhaust

-Lightened and balanced bottom end (crank and flywheel)

-forged pistons with flat tops

-std rods

-vernier pulley

 

They also said the engine was jetted for carbs but he's a bit dubious of there claims because of the problems he's had with the company.

 

What he would like to know is either to run carbs or TB's? he's been speaking to a friend in Scotland and he's saying TB's as there a more smoother power delivery??

 

Also a clutch option?

 

Please excuse my lack or knowledge in this as i feel I'm in way over my head here because i don't fully understand much of this, as i said its for a friend who's in doubt of what to do.

 

oh and the car is used for road rallying.

 

Any info and advise is welcome and if there's anything else you might need to know then i can ring my friend and ask.

 

Thanks in advance

 

Will

Unfortunately seems to be common-place with this company these days. And unfortunately i'd be a little dubious of the spec, especially considering the very little info they're reluctant to give.

 

Bodies and management will give better drivability, smoother delivery and suit the engine better, and arguably easier to set up once and forget, then make easy changes if necessary. Carbs will be nearly as good with mappable ignition, the dizzy will always be limited, and at the very least needs to be a re-weighted/curved item for this spec.

 

Clutch-wise, a good OE one should take the power ok, budget comes in here though, depends what you want.

I know he is leaning towards bodies and management but was in doubt about what to do, he doesn't mind paying a bit more for a better setup (eg TB's and management over the carbs) as he's gone so far with the engine but its which setup to go for.

What about the Jenvey setup you have for sale Baz, would that work with the right manifold as its for the MI iirc?

 

As for the clutch he doesn't mind paying a couple of quid for a decent ceramic as he's finding the OE one slipping with his lightly fettled 1.6 he's got in the car now.

 

Cheers

Yeah sure, with the correct manifold will all fit! I keep toying with the idea of ditching my carbs and fitting this set-up on my Longman 8v too!! :D

 

The clutch if a decent make as OE; Valeo/Luk/Sachs etc, really should be well up to the job of harnessing up to 200bhp, so there may be something up with his!

Ooh right, i did mention your TB setup to him earlier and he seemed quite interested.

 

It could be a different make of clutch he has im not 100% sure.

 

Pm'd :D

The most common over bore size take the engine to 1598cc iirc with easily sourced 83.5mm liners but afaik using forged pistons mean the rods will also have been bushed to suit because the set I have here for a 1.9 engine are & afaik they have to be like this.

 

How is an engine be jetted for carbs unless its sold with them fitted ready to run?

 

Like Baz says, mappable ecu & TB's will be the best if its set up by a reputable company using their preferred mappable ecu (Emerald, DTA etc).

 

I agree with the clutch remark from baz but maybe he wants to go for a paddle clutch if he's that worried.

I'm sure LAD where meant to supply carbs with the engine but this being one things my friend never received (I'll find out more about this tomorrow), he's been taken on a bit of a ride with this engine and is getting sick of chasing LAD up about things.

 

As for the bore size LAD where reluctant to say much but my friend is saying to me 1600cc, but from what you have said it could well be 1598cc as he is a little unsure himself.

 

I'll also ask about the clutch again tomorrow as he didn't mention paddle clutch to me but ceramic (sorry if i'm being dumb, i'm not really clued up on this myself :ph34r: )

I was speaking to my friend today and found out he's been screwed quite badly with this engine.

He paid nearly 5k for ths engine and over 18months later he's still missing the carbs, manifold and clutch. on top of that he also paid for a 22mm ARB, group n gear linkages, bigger front discs and mounting brackets and a distributor for the carbs all of which was not recieved.

 

He been a bit unlucky but is soldiering on regardless, as for clutch options Graham mentioned a paddle type clutch where would be a good place to start to look for one? He would just like one that has a better 'bite' than an OE one.

 

Thank you for your replys so far it has been a really big help.

 

Cheers again

Shenpar list a ceremetallic clutch plate (~£200) but other places such as Demon Tweeks might have these bits.

 

Special tuning UK sell ceremetallic plates also.

Thanks for your reply Graham, I'll forward this info on to him so he can see for himself and make a decision of what he wants to go for.

 

Cheers again

I don't want to put a dampener on things, but are you allowed to run tb's on road rallys ?

Tbh I not sure myself but the lad who's engine it is never said that there not, I'm unsure if the reg's are different across here but he's been rallying his 205 for a good few year's now so he's probably aware of whats allowed and whats not.

 

Cheers for pointing that out anyway though :D
