Haltech Nexus S2 ECU + plug&play adapter harness (Honda Civic/CRX/Del sol/Integra 88-01 with OBD1 Conversie)
80% of the products in our store are in internal or external stock and we can often process your order quickly (varying from a few hours to a number of business days).
Naturally it is possible that a product has an (unexpected) longer delivery time.
Upon receipt of your order, we will always inform you about this and offer any available alternatives.
We deliberately provide stock information about our products afterwards, because many suppliers do not offer a ''stock link system'' and we do not want to show '' estimates '' in advance, like many other webshops do (which are often incorrect and give you wrong information in advance).
We only want to give our customers actual information on the moment of processing the order so we don't mislead our customers.
If you need a product VERY quickly and you need to be sure that we have it in stock, please e-mail or call us or send a message via ''ask a question about this product''.

PLEASE NOTE: This system is originally designed to work with the specific chassis models with a B-serie engine between 92-95, but when an OBD1 conversion has been made in other chassis/engines Like the EK (96-00) or ED 88-91) models with for example a D-serie engine, the system is also usable.
As long as the OBD1 conversion has been done right already.
